How do you think the US Air Force and the US Department of Justice
websites were hacked? Grab the passwd file, run crack, log in and 
slash and burn. Good thing FreeBSD uses shadow passwords, eh?

But the spammers use this trick too so just make sure that you delete the
useless phf program from all your servers if it is still there.

You can all thank 2600 Magazine. last month they did an issue on phf and
how to crack it. Interesting article, but since the problem was solved a
long time ago, the article is useless.

You can get the SMC Elite Ultra (8216) cards from Onsale for
somewhere around $10 each.  Since it is an "auction", the price
varies, but the six-packs usually go around $60 or so.

They are selling 10bT cards now, but I got 84 of the 10b2 cards
a couple months ago for average $8 each.  They're ISA, but make
the NE2000 cards look like the crap they really are.

I recently FTP'd some 600 megs from a Pentium with PCI Ethernet
to another Pentium with the SMC (ISA), and got around 1.06 meg/sec.
CPU utilization on the PCI was ~20%, on the SMC ~30%.  Not bad.

If you want a good PCI card, get the Kingston KNE40.  It has the
DEC chipset and works beautifully on FreeBSD.  Costs around $50.

Now stop recommending NE2000 cards, PLEASE!

All the best,

-Richard

For an ordinary little phf probe from some h4ck3r-wannabe, I might let
it slide. If it's something more determined, or if it's coming from a
host that shouldn't have regular lusers on it, then definately inform
root or postmaster at that site and the technical people for that
domain and network, as listed in the whois database.

Not all hackers are clueless wannabees. Once root is cracked, it's
possible to be completely invisible on that system. The legitimate
operators of the host have a right to know what their resources are
being used for. If you don't tell them, they might never know.

Take a loot at your named.root (cache) file and make sure you have the 
approriate addresses for the root nameserers. If you do not, just query 
the addresses by using someone else's nameservers like
nslookup
>server [ip address of a ns here]
then query for the addresses of the root nameservers and plug them in.

Yes, check the advisory on phf that came out several month's ago :-) ..
phf I guess passes user input into a shell, so it is possible to trick 
phf into executing shell commands as the user of the webserver.

It depends on what was done, and how good ones logs (and the originating
ISP's are) and how far away it was done from.

Ive found government agencies will talk up how well they will pursue such
things, but it its not a death threat to the president, or obvious kiddy
porn - they dont act.

I've noticed some oddities over the last 6 months with some networks
or carriers. I can't pin down which. I have found two companies so
far that have trouble retrieving info from over here. Yahoo and 
Linkexchange are two. This is most noticable when they are trying to
retrieve something from my site using their cgi scripts to either update
search engines, or in the case of linkexchange, retrieve the banner.gif to 
put in their database.

Now this is the odd part. Both sites show that they have immediatly
accessed my site. They show up in the access_log as doing what they are
supposed to do. Then however they time out, or fail. Yahoo fails on
timeout, even though they have actually accessed the page being indexed,
and Linkexchange failes with a Server Error from their site.
I had a similar report from a person in Germany, but couldn't get back in
touch with them as they went to China!

My link here is only 28.8, and I know that this could be the source of 
some problems, however, I am beginning to suspect something much lower
down the chain.

SMTP also fails repeatedly, mostly with timeouts, on only certain sites.
Some (most) go through immediatly, others NEVER go through? yet if I rout
them to a nearby server at the local college, which is only one hop
away, they go on from there immediatly, over it's 64K link.

Now, is this purely a 28.8 problem, thus something I live with for the 
moment, or is there some sort of underlying timing problem here that
I can maybe fix in the kernel.?
Or indeed, is it even my problem at alll? I can't believe I'm the only
person in the world working at 28.8K?

Does anyone have any similar experiences, or ideas.

Please dont just tell me that I should upgrade to a higher speed. I can't.

thanks
Robert

Your problem is that eros.chalmers.com.au is an Annex, and Annexes munge 
tcp extensions.  Turn off the TCP extensions and you'll be happy.

HELP ETRN
214-ETRN [ <hostname> | @<domain> | #<queuename> ]
214-    Run the queue for the specified <hostname>, or
214-    all hosts within a given <domain>, or a specially-named
214-    <queuename> (implementation-specific).

 Using both this and the suggestion that David suggested would be the
 best IMHO.   Your host (freebsd workstation) is the primary MX which
 redirects mail to smtpgate.there.host which is queued when they are
 not connected.

 When they connect get them to stuff a ETRN at sendmail and watch it
 all start to flow.    Its probably worth getting the sendmail book
 and reading up on queue management.  The "new" version of the book
 should be out soon.

 If they say can't connect for a day or two you would then want to
 know how to stop everything bouncing.   Its pretty much a must-have
 if your working with mail :)

 Hmm.. think once I wrote a 12 line shell script that limited users
 in the dialup_users group to 2 hours per day.

 Its pretty easy.. just use a few unix utils grep'd, sed'd, awk'd and
 your done.   I've seen some interesting time-watching code based on 
 user classes and rulesets (email davo@katy.apana.org.au for more info)

 If your interested in that script I could dig it up and post it to ya. 
 Volume limiting would be more interesting, but I haven't done it. 

 You could also look at the login-classes stuff that David Nugent is putting
 into freebsd-3.0-current, or there is a "radius-terminal-server" package
 around somewhere that turns a PC+serial ports into a radius (tm) compatible
 box.

I don't use CRL directly, but I do have a secondary connection, with
Ironlight Digital, which utilizes CRL.

My experience has NOT been very good. However this is a Fram Relay
connection I'm talking about; maybe their pt-to-pt network is better.
However, I've experienced a LOT of routing problems and packet loss in the
past... It's definitely been annoying. :(

Do you know if Livingston Portmasters have the same problem?
I am seeing corrupted packets arriving at my Ascend Pipeline 50
from my ISP's Livingston PortMaster (don't know the model).
Most packets make it through, but I see certain packets in
FTP and HTTP connections that never make it through the
port master.

Thanks,
++Brian

 Greetings All,
 
 Is it possible to have multiple IP addresses on one machine without having
 multiple ethernet cards..
 
 Once I wrote a note about setting up user www pages, this question started
 a thread about how to configure your system as
 a new sysop, Anyways, people where talking about having different domain
 names IP addresses on one machine so that when you outgrew it, it wasn't a
 big hassle to change.
 
 Here is the deal, 
 
 We want to have one computer (for now) that runs DNS, WWW, FTP, TELNET,
 POP, PPP and anything else.
 We have a 2 mbit IP Feed, and will be the only service providers in the
 country (Alania, part of the Russian Federation).
 That means we will be the only providers in an area of about 2 million
 people. 
 
 We want to have
 
 www.rno.ssc.ac.ru 
 mail.rno.ssc.ac.ru 
 ftp.rno.ssc.ac.ru 
 telnet.rno.ssc.ac.ru 
 dialup.rno.ssc.ac.ru 
 admin.rno.ssc.ac.ru 
 
All running on one machine, whith the ability to expand and move each
 service to it's own machine without having to have all the user change
 thier configurations.
 
 I would assume it would just be a matter of putting multiple names in the
 /etc/hosts file and using the same IP address
 for the every aliase. (How would this look? would I put a local host entry
 in front of every aliase?)
 
 But moving the service from this machine would have to change the ip, is
 there anyway to aliase IP addresses and
 have that address move with the aliased hostname?
 
 Those replying, (I'm not on the list, to this address) plase send your
 address, We'll send 500!!!! Russian Rubles for your answer <grin>
 
 Thanks a Million,
 Dave

Check with your ISP to see if they have any filters setup on the
PortMasters.  They might have something incorrectly configured.  However, I
have found the Livingston boxes to be very reliable...

And if you reply to his request you won't find him.  The domain he used 
in his address is "shopnet.com", which just happens to belong to us.  I'm 
sure he meant to use a Russian based domain name.

I am finally sick of my pathetic NT Webserver.

I feel comfortable enough now with FreeBSD to move
my Websites over to Apache.  Even with my limited UNIX experience
FreeBSD *HAS* to be more reliable than my often down NT server.

I am writing in the hope that more experienced FreeBSD 
WebServer operators can give me some tips and pointers.

I would like to be able to host about 2000 personal 
Web directories, and a few business sites.

Some Questions:

- Users should be able to FTP to their directories,
but I don't want to allow shell access. What is the
best way to set this up?  Is a shell=/nonexistent
adequate?

- Do you think this hardware would be appropriate?

Pentium Pro
Tyan MB
64 megs EDO ram
Quantum Fireball 2Gig scsi
Seagate 1Gig scsi
Adaptec 2940
Intel EtherExpress Pro/100b

- What partitioning, and directory mounting strategy would you recommend
with the drives stated above?

- Also, I'm concerned about the 8 character limit on usernames.
Is it safe to modify the username char limit on a machine that
will be a webserver only?  And if any wants to save me a trip to 
the list archives, how is this best done?

Thanks in advance, as always,

Matt Eagleson

I'm still on the trail of this ratty connection. The really odd thing is
that SOME people practically can't connect at all, yet others have no
problems and simply stream through. Take this person for istance;
Out of many so far who have connected and ftp'd the nslint program with
apparently no problems, ( maybe they have just put up with theproblem?)
Philippe doesn't seem to be even able to connect at all. His message
shows the classic symptoms. Bad sendmail exchanges, and ftp simply dying.

Hmm.  I saw his e-mail address as <dave@ssc.ac.ru>.  Are you sure your

Wierd, in the from address in Pine it had: ssc.ac.ru.shopnet.com.  
Somehow his address got appended to ours.  I've never seen that happen 
before.  Gawd, don't you love computers sometimes. :-)

This is really a candidate for the upcoming HowTo section of the Handbook.

You don't need multiple IP addresses for this.  You want to use the DNS 
to manage this.  Simply list each service separately in the DNS and make 
sure that users use the correct name for the service.  When you want to 
split to multiple machines, simply reconfigure the DNS.  Easy.

Start:

(zone file for rno.ssc.ac.ru)
admin  IN A 1.2.3.4
ftp    IN CNAME admin
www    IN CNAME admin
telnet IN CNAME admin
mail   IN CNAME admin 
  
Note that a CNAME record *must* point to an A record, not to another CNAME.

After split:
admin  IN A 221.2.3.4
mail   IN CNAME admin 
telnet IN CNAME admin

www    IN A 221.2.3.5 
ftp    IN CNAME www

Yes, but don't use the hosts file, use DNS.  There are some DNS primers 
out there on the 'net. (Can anyone recommend URLs, please - I'd like to 
digest them into a FreeBSD HowTo)

You can put multiple IP addresses onto a single machine.  There are two 
basic cases:

1.  The aliased address is part of the same subnet/network as the primary 
    address.

In this case, you need to specify a netmask of 0xffffffff (8 f's) and put 
the alias onto the primary ethernet interface, e.g. ed0.
# ifconfig ed0 221.2.3.4 netmask 0xffffff00
# ifconfig ed0 221.2.3.5 netmask 0xffffffff alias

When this happens, the machine will respond to arp requests for both 
addresses.

2. The aliased address is part of a different subnet/network from the 
   primary IP address.

I find that the best place to put these aliases is onto the lo0 interface.

# ifconfig lo0 219.5.6.7 netmask 0xfffffff0 alias
# ifconfig lo0 219.5.6.8 netmask 0xffffffff alias
# ifconfig lo0 219.5.6.9 netmask 0xffffffff alias

Note that the first alias in a given net/subnet must have the correct netmask
for that net/subnet, while additional aliases use the netmask of all 1's 
(0xffffffff, 255.255.255.255).

Since these aliases are part of a different subnet/net from the local 
ethernet, other machines on the local ethernet must be given routes to 
the network using the aliased machine's primary ethernet IP address as a 
gateway.

Danny

Don't know.  The symptoms are a "connection" followed by no data flow.  
Is this what you see?

Diana, I'm not sure where you looked, but all of the headers I got from him
reference ssc.ac.ru, which is where he is at. I have dealt with him before
and he is legit (I even got a couple of ruple notes). Maybe you were
looking at how the mailing list was addressed?

 Hmm.. i'd suggest running something like nntpcache that allows you
 to then have like a web-cache type arrangement for nntp traffic.

 When your clients have requested/read an article via this "cache"
 software, which pretends its a normal newsserver, it is cached
 and expired etc.

 The amount of bandwidth utilized for this arrangement is *tonnes*
 less than even a partial news feed.  The only disadvantage is that 
 you then can't provide active feeds to sites.  

 Also there is a leafnode news package which is sort of similar.

Okay, it must be my system.  Running PINE on my FreeBSD box, 
ts.shopnet.com, showed Dave's address as <dave@ss.ac.ru.shopnet.com>.  I 
don't know why, it's never happened before.  I've been running PINE for 
a couple of years and it never did this before.  Anyone have any idea 
what glitched?  Someone did suggest that possibly my system didn't 
undestand the .ru root domain and therefore it appended my domain on it.  
I get mail from all over the world and this has never happened before.

So, I apologize for the waste of bandwidth.  This is the last I will 
waste on this topic. :-)

It's not PINE, it's the wildcard MX record you have for shopnet.com

Robert,

I can't send mail directly to you either!

Try building a kernel with 
pseudo-device bpfilter 4
and then listen to the ethernet with tcpdump and see what happens.

I seem to be having the same problem no matter when I try the connection 
to the ftp server...always the same quick connection and chdir and ls but 
the actual get takes forever err never even transfers 1 byte. :-(

What are folks running news servers doing to keep /etc/security from
traversing their news spools?

It's too bad we don't have ncheck, but it looks to me like the next
best thing would be to skip any filesystems mounted "nodev", and either
"nosuid" or "noexec".

There's a similar problem with /usr/libexec/locate.updatedb that
/etc/weekly runs to rebuild the location database, and you probably don't
want to use the mount flags trick here.

So it seems that the Annex may be the culprit in my long standing 
connection woes.!!! bummer dude. Can't see anything else in the stream,
and I haven't got a hope of translating anything I see in tcpdump.
I like the line (You will find tcpdump most useful) in the man page. Really!
Need a short course in it I think.

Anyway, the saga continues. Now, I may try and set up ppp in auto mode,
only needing to dial out and stay connected. I'm going to have nightmares
over this I'm sure. I have read the handbook, and it looks easy. Famous
last words. How do I stop it from timing out, and hanging up though!
I have my own IP class C, so thats easy, static IP section. Gateway
and IP forwarding so the rest of my net can see out.

Seems overkill, when this outrageously expensive Annex should be doing the
job... oh well. see the manufacturers as they say :-)

In the hopes that someone more knowledgable than I may have an explanation.

I realise this is not in bug report format.
FreeBSD nanguo.chalmers.com.au 2.2-961014-SNAP FreeBSD 2.2-961014-SNAP #0: Tue Jan 28 14:23:53 EST 1997     root@nanguo.chalmers.com.au:/usr/src/sys/compile/MYKERNEL  i386

I am connected to the carrier (ISP) through my Stallion EasyServer 8 Port.
This is an Annex the same as the XYLogics Annex. Running V9.xx software erpcd.


The problem that has surfaced;

	Some, not all, sites around the world are not able to connect
to any of my FreeBSD servers to exchange information. Let me rephrase that:
They can connect, but not exchange information past that point.
I have no idea what OSs the other sites are using. The number of sites is
not large, but significant. I am currently logging over 4000 connections a 
month from individual places. Well over 1GB of data transferred.

the Problem.
	examples:
1.		mail (sendmail) to some sites can only deliver 1 line 
		messages. To other sites not at all. The sites report back
		with timeout and other messages indicating a failure to 
		complete transactions with my site

2.		ftp from other sites into the ftp server will connect then
		hang, and the connection is reset.
		Most interestingly, one freebsd site changed to a Linux
		server, and connected fine, and completed the transfer.

3.		http/web servers will connect and hang, others will go so
		slowly that they are as good as unusable.
		Most notable are yahoo.com and linkexchange.com. 

		All the
		other search engines connect and exchange data with no 
		worries.

		It should be noted that linkexchange.com will talk happily
		to this site, EXCEPT when it is required to SUBMIT my
		banner for its archive. It connects, then I get a server
		error from Linkexchanges server. Yahoo simply fails
		all together. The error returned is a timeout.


Systems known to work with my site with no worries.
	SCO Unix
	BSDI
	NT
	'95

I can connect to, and be connected to these OSs with no worries. 
I have tried setting tcp_extensions NO and YES. If set to YES, I am unable
to ftp to another FBSD site that also has tcp_extensions set YES (on).
The connection simply 'hung'. If I set rfc1323 to 0 (off) the ftp connection
worked fine, the other end being (on). The same happened at the other end, 
when they tried to ftp to me. set tcp_extension on, fail, set it off, fine.

The only constant is the Annex. However, why does it pass _most_ traffic,
if it is the fault of the Annex, and only fail on some.? 

If FreeBSD is
going to be so fussy about its tcp/ip flow, shouldn't it be reworked.
The world is still full of less than leading edge hardware! Some of it
brand new...

If anyone wants to comment or offer help, I'mm happy to keep trying to
track this bug(ger) down.

cheers,
Robert

me why the netmask has to be different.  Personally I don't specify
a netmask for the aliases and it seems to work out OK.   Any offers?

Hmm, I'm seeing problems with the Annex's too if I run with tcp_extensions
enabled. Somehow the Annex's turn some of the trafic into "chernobyl" 
packets (ie all lamps and bells set). This is only a problem
if the other end also supports the extensions (ie a FreeBSD box).
However all problems dissapear if I disable the extensions.
I guess the only solution is to bug the vendor to implement a 
modern IP stackc...

Disable the tcp_extentions is the only solution to the problems I'm
seeing as it is not the FreeBSD end that is at fault, and hence I
cannot fix it :(

I had similar problems using annexes as term servers with user - and have
posted numerous times that this problem only exists with freebsd  - sco,
linux, etc doesnt have trouble - only every time I post it I get bashed
about the head and lectured on freebsd having perfect tcp/ip and
everything else in the world having faulty tcp/ip.

So good luck to you sir!

I would certainly volunteer server space, we're an ISP in Michigan running
12 FreeBSD boxes with fully redundant Internet connectivity.

Xylogics Annex terminal servers running a s/w release PRIOR to 10.1 don't
pass the RFC1323 and RFC 1644 stuff properly.  If you set your
'tcp_extensions=NO' it should work just fine.  Also tell your ISP to
upgrade!  I did and it works just fine!

Hmmm...  

How does this work the other way; ie: users dialed in to an annex with
Windoze/Mac hitting a FBSD server somewhere on the net.  Do they see this
problem as well?  We've had *alot* of mysterious problems with our annexes
running R10.1A.  Users report similar problems; the initial ftp connection
builds OK, but then as data is actually transferred, it slows to a crawl.
Seen it with http as well, and an sz over a telnet connection.  Have yet
to track down why some people dialing in see this and some don't.  We just
purchased R3.1 (11.?) in hopes it will help.  What version of software is
the Annex you are using running?

Ok, I've obviously screwed something up.  I just did a fresh install of
2.1.6, and made the following changes to the kernel:

options         "CHILD_MAX=512"
options         "OPEN_MAX=512"

options         QUOTA

I also changed UT_NAMESIZE in <utmp.h> and MAXLOGNAME in <sys/param.h> per
conversations months ago in this forum.

Recompiled the kernel and now I can't do a simple ps -ax.  I get the
following error message:

yacko: {5} ps -ax
ps: proc size mismatch (17472 total, 620 chunks)

Anyone care to tell me what I might have screwed up.  I've tried rebooting
the machine to no avail.

Thanks in advance.

Have you tried switching off the TCP extensions? See /etc/sysconfig, you
can turn of support for two related rfc-s there...

I asked on this list not long ago for the MicroSoft FrontPage Extensions 
for Apache. Most people were under the mis-understanding that they do not 
exist. If anyone would like to install FrontPage Extensions v2.0 for 
Apache, they exist at http://www.rtr.com (link right off the page).

Did you recompile ps and the rest of the utilities?  When you change the
kernel stuff, you also need to let the utilities know that a change has
been made.

  FreeBSD implements T/TCP.  You can disable this via by turning
tcp_extensions off.  SCO, Linux do not implement T/TCP, which is to their
disadvantage.  T/TCP gives you big wins if opening and closing a lot of
TCP connections.

  Broken boxes like the Annex don't like T/TCP (it is broken, because if
the Annex properly implemented IP/TCP, it wouldn't have a problem).  Newer
software releases for the Annex fix this problem.

  I'm not aware of any equipment that doesn't like T/TCP that couldn't be
fixed with a software upgrade.

I don't understand what you are saying here; if you are saying that
it works with extensions off, then it is easy to explain:

o	All TCP/IP implementations *must* support extension
	negotiation for locally unsupported extensions (they
	are to negotiate them "off").  Not all TCP/IP
	implementations are conforming.

o	All TCP/IP implementations *must* support data in SYN
	packets, even though most implementations do not generate
	data in SYN packets.  T/TCP will generate data in SYN
	packets; so will the FreeBSD "finger" (man finger).  Not
	all TCP/IP implementations are conforming.

If you detect a non-conforming implementation:

1)	Contact the vendor for a fix; one probably exists.

2)	If no fix is available, turn extension off on the FreeBSD
	system, and submit a bug report to the vendor so that a
	fix will happen.

If you think things are bad now, wait until the net begins migrating
to IPv6 at the router level.

Please notify Annex that their TCP/IP implementation is non-conforming
int the area of option negotiation (the "Cherynobl packets", where if
any option bits are set, all option bits get set).

They are non-compliant with forwarding of SYN packets containing data,
since they strip the data.

They are also nominally non-compliant with extention negotiation, since
they should negotiate with the host to turn extensions they do not
support off (ie: RFC 1323 and RFC 1644).

They also do not implement RFC 1323 or RFC 1644 (they *must* implement
*all* extensions they fail to negotiate off).


In short, we *claim* they are broken because they *are* broken.


If you wish to be able to interoperate with faulty implementations,
you can always turn off the extensions which trigger the problem
with the faulty implementation.  Meanwhile, it provides a nice
diagnostic for detecting bad TCP/IP implementations, which will
only be going to hell in a big way all at once when IPv6 gating
comes online, otherwise.

Turning extensions off does not stop the problem.

I know you checked to see if the TCP extensions were the problem.
Have you checked for buggy V-J compression code on either the
Annex or whoever it's talking to?  I.e., try turning off V-J
compression on the Annex, and see if things improve.

Does the remote system triggering the problem have extensions enabled?

I believe the extensions setting in FreeBSD just changes the default
state, and if a remote host negotiates them on, they will be on for
that session.

Are extensions off on *both* ends?  If so, *exactly* what do you
see happening, and for what programs?

Yup - It was with users - only some - same problem as the other guy has..
They would connect to the news server, and not be able to pull headers -
or to the web server, and get the text but not the graphics.  It would
stall.

The bandaide I put on it was to number all freebsd boxes on class C's
other than those of my annexes, forcing the packets thru my cisco.
Everything cleared.

Then something else is wrong!  I used to have to turn the tcp extensions
off to connect to my annex but after upgrading to 10.1 it went away
entirely!  I've got about 400 users using my annex at this time, most from
windoz[95-n/t], but quite a few using freebsd.  works like a champ!

And you are positive that you are using Annex software 10.1 or better,
and/or none of the machines are sending data in the SYN packets?

The TCP extensions do not bear on whether or not data will be sent in
the SYN packet, I don't think.

Since there has been a great deal of discussion of tcp connections
hanging
when passing through annexes, I thought I would bring up the problem
that I am
having.  The symptoms are *very* similar but the hardware is different.
Perhaps my problem will shed some light on the other people's problem.

I am running 2.1.6-stable connected to the Internet via an Ascend
Pipeline 50
router on my end and a Livinsgton Portmaster (unknown model) at my ISP
over
two ISDN b-channels.  My ISP routes my traffic through a CISCO router
(unknown
model) to UUNET and then to the Internet.

The symptom that I encounter is as follows:

  * Client on my side opens ftp connection to certain sites.

  * Client begins file transfer and connection seems to hang after
    some data has already been transferred.

The sure way to reproduce the problem is to ftp to ftp.caldera.com, cd
to
pub/mirrors/redhat/updates/i386 and type dir.  Only about half of the
directory listing makes it through.

In addition, sup fails every night and I was unable to install FreeBSD
using
FTP because of this problem.  I have also seen the same lock ups as have
been
described by others including NNTP headers and image transfers for web
pages.

The problem happens regardless of the tcp_extensions setting in
sysconfig.
Also, I have seen the exact same problem with Windoze 95 clients.  I
also saw
the problem with linux 2.x kernels but not with linux 1.2.13!

What happens can be seen from the tcpdump output included below: The
Livingston/Ascend never manage to pass the packet containing octets
2485-3945
down to my network.  My FreeBSD box keeps asking for a retransmission. 
No
matter how many times caldera retransmits, the bytes never make it
through.
It appears from the Pipeline's stats that the Pipeline is rejecting the
packet
as having an invalid header.  So I suspect that the Livingston is
corrupting
them, but I do not know that for sure yet.

If anyone has any ideas or suggestions I'd be happy to hear them.

++Brian

PS - I used caldera.com as an example of a site that I have trouble
     communicating with.  I am not claiming that this is their fault! 
They
     are simply an innocent bystander.

Here is an excerpt from the tcpdump of my side of a hung ftp to caldera.

With a double lookup.  What a waste of bandwidth.
Q whois test?
A test=WWW
Q whois WWW?
A WWW=Zero-Cool, IP=10.10.10.1

Another common misconfiguration is pointing an MX at a CNAME, e.g. 
hades.org. IN MX 10 test.hades.org.
(Generates error "hades.org has CNAME and other data").

What version of FreeBSD are you running?  In the later versions, the 
netmask 0xffffffff is required.  I think it might be to do with 
preventing broadcasts multiple times on each interface, but perhaps the 
person who made it like that can comment.

Just wondering, but would it be possible to detect these bogus packets 
from the Annex and revert to no-rfc1323 for the connection?

And for Robert: If you read RFC 1323, you'll find that it deals with TCP 
sequence number wrapping on log fat pipes, so unless you have a 155 Mbps 
ATM connection to Melbourne, you won't need RFC 1323.  After having 
problems like this with someone in Melbourne who could not send me mail, 
or read my WWW server, I have disabled RFC 1323 extensions on my main 
boxes so that Annex-crippled people around the world can talk to me.  My 
512kbps link means that there is no point to the extensions anyway

I'll send you the RFC.

Danny

Jeez, I'm not sure why I'm getting involved in this, but Terry's
exegesis of Brian's packet traces is incorrect.  What's really
happening is that one packet from Caldera (the one containing bytes
2485:3945) is consistently getting dropped somewhere between Brian's
ISP and Brian.  I'd look closely at the link between Brian and his
ISP (Ascend Pipe50 <--> Livingston Portmaster, over 2 ISDN B-channels).
Possible causes include:

	* flakey hardware;
	* buggy MLPPP on either the Ascend or Livingston ends;
	* buggy V-J compression on either the Ascend or Livingston ends;
	* (your good idea goes here).

My bet would be that the Ascend is dropping the packet because it
thinks (correctly or not) that it has a bad PPP-CRC.

For masochists, here is my annotation of Terry's packet exegesis; my
comments are marked with -->, and Terry's with XXX, where I think he
went astray:

Well, turns out that a Linux 2.0 box also stalled on this.  However, 
methinks it might be time to raise the issue of default settings for RFC 
1323 extensions in FreeBSD boxes.

Since RFC 1323 deals with long fat pipes, which very few of us have, it
would make sense to turn the extensions off in the shipped /etc/sysconfig. 
Those people who are communicating with TCP between the two ends of a 1.5
Mbps satellite link, or an intercontinental 45 Mbps link, probably know
who they are and can turn the extensions on.  I know that some people in
the continental USA can claim a 45 Mbps path to their favourite ftp site 4
states away, but surely those paths are used by others, reducing the
'fatness' of the pipe for RFC 1323 purposes.  Local area ATM might be 
'fat' but generally is not 'long' enough to cause the problems with RFC 
1323 addresses.

Leaving the extensions on by default causes much grief for people with old
Annexes, prevents people whose ISPs use Annexes from reading FreeBSD box
web pages or sending mail to FreeBSD boxes, and generates enormous amounts
of traffic on the FreeBSD mailing lists.

Danny

Ah, but it does.  It's just that other FreeBSD systems (like Yahoo) still
have them turned on, so the Annex is dropping its guts regardless.

As has been mentioned, the _correct_ response is to tell your provider
that their Annex is _BROKEN_, and that they need to upgrade its
software (which I believe is a free exercise, but you can ransack
Xylogics' website for details there) preferably before you take your
business elsewhere.

We are not using T/TCP.  That is RFC 1644.  T/TCP may well be broken in 
Annexes, but it is RFC 1323 extensions which cause the current grief.

Hello.

Does anyone has a ftpd, where you can set the access control for
each virtual domain ? Like allowing anonymous, or not ?

agreed, although it is sad that such an approach practically bans
any TCP extension because some broken equipment won't support it.

not that it helps much since in many cases the application have
hardwired settings for small (<64K) windows. As a matter of fact,
has anyone been able to _actually_ make use of >64K windows (i.e.
withouth the system changing settings under your feet) ? If yes,
which version of FreeBSD ?

fast ethernet also peaks around 10 KB/ms, which means that going
through a couple of (fast) local routers (not switches) might as
well bring you close to BW*RTT > 64K

	As a data point - running a local-area ATM with "out of the box"
parameters (for 2.2 this looks to be 16K windows with no-scaling), I get
60 KB/s out of the box vs 3.0-3.5 MB/s into the box, [notice the really
bad discrepancy] via ftp. With larger windows (60KB), I can get in the
range of 3.5-4.0 MB/s [either 'put xxx /dev/null' or 'get xxx /dev/null'
so local disk access is somewhat unrelated. That is, the numbers don't
vary much if I'm sending from local disk or receiving to /dev/null.]

	Using ttcp (tcp user application, memory to memory), I've transmitted
close to 70 Mb/s, in the "local-area". I'm not sure that getting twice
the throughput counts as being 'not long enough'.

[I'm simply providing this as a data point for the discussion, not attempting
or interested in arguing for or against either side.]

   The traces that have been posted don't show that as being the problem. TCP
extensions cause problems at connection startup and the traces are showing
that a regular data packet is being dropped. One possible reason that this
problem is being noticed when FreeBSD machines are involved might be due
to FreeBSD's Path MTU Discovery causing the packets to be large. It seems
likely to me that the Annex can't deal with large packets some or all of the
time and drops the packet rather than fragmenting and/or without sending the
proper ICMP message (which would break MTU discovery).

   Oh, and BTW, only one side needs to have them disabled for them to be
disabled. I highly doubt that Yahoo has the extensions enabled, anyway. I
certainly don't on wcarchive.cdrom.com.

   Actually, the main reason it is on is for the other half of RFC 1323 which
specifies the "time stamp" extensions for better round-trip time estimates.
Unfortunately, I agree with you, however, that RFC 1323 extensions should be
disabled by default. The RFC 1644 extensions (T/TCP), however, should remain
enabled by default. This will only break "finger", and is useful for keeping
vendors TCP stacks compliant.

You forgot "and gets Annex box owners to take advantage of the free

   He's mixing bits and bytes. Pay attention to the case of the "b".

FYI:  I get the same failure on  Solaris 2.5 (from a different network
point of view even) as I do on the FreeBSD boxes at my shop.

So, anyone else got this file that wants to share it :-) :-) :-)

I have a Pipeline 25 (4.6C software) connected to a Portmaster 2-e w/BRI
board (ComOS 3.5). I see the exact same problems as well. I am unable to
use my FreeBSD laptop from the Pipeline LAN. It does get to the point
of transferring data, though. When I tried to install FreeBSD from the
Pipeline LAN the first few bytes of the bin dist made it through. The
laptop works fine dialed into the Portmaster via modem, though. Therefore
I do not think it is the Portmaster, although who knows? Maybe the
Portmaster is munging the packets and the Pipeline is less liberal in what
it receives than FreeBSD?

I will have to get tcpdump running on the Portmaster LAN and the Pipeline
LAN simultaneously and see what I can see.

Don't you have to run apache as root in order to get the
Frontpage extensions to work? This is what i read in the docs --
if there's another option, please let us know.

Please put a stop to these "free upgrade" rumors...  I've called and
begged and pleaded with these people.  Without a support contract they
will not talk to you about the problem, and without the software-upgrade
contract they will not give any software away...  In a nutshell, they are
a pain in the ass to deal with.

Now, that being said, I'm not ready to start pointing fingers at anything
yet. It should be noted that using TTCP with window scaling and going to
large socket buffers, I've seen 68.58 Mbits out of the machine, and 96.97
Mbits into the machine. I have not run the simple ftp test over ethernet,
nor have I looked into why the ATM transmit is so slow. [We're gennerally
pretty good at figuring this stuff out, we do it alot over wide-area ATM,
including links with satellites.] I really need to do some more investigation
of the ATM software, as well as repeat the tests using ethernet. [I should
be receiving another pentium machine in the near future. I'm trying to arrange
for a second ATM card, as well as some 100Mbit ethernet cards.]

My point in the post was only to provide a data point that perhaps we (being
the FreeBSD community) ought to think and ask more questions before taking
the easy road of "turn it off." [Not that this might not be the correct
answer.] It would be more work to go back later and say "opps, we solved the
wrong problem and need to turn extensions back on as the default."

Anyways... like I said, just a data point for consideration...

No, you don't.

We support the MS Front Page Extensions for any customer that wants to host
the domain with us. The WPP kit allows for a SUID install of 12k binaries
that load the real program - however, with the ownership of the site's
owner, instead of as root.  That way, they can't do any harm; they don't
have root; and they still have FrontPage.  It actually works really slick
for this purpose.  I'll be giving the MS test to our site this week, and
then applying for the Bill Gates Seal of Approval [kiss of death?] to be
put on their marketing page.

For www/~username users... we're still experimenting.  I'm so far not found
of what I am finding for ~username handling, and resorting to making a
subweb off  of a specific virtual host for each user that wants it (and
then cutting off telnet/ftp access to their WWW directory).  The virtual
host hosting data for the individual users wanting frontpage style access,
forces the frontpage extensions to run as a user of "frntpage", and no user
is a part of the unix group that frntpage is in - hence, cutting out
external editing.  If they decide they want to stop using frontpage, I'll
return ownership of their www directory back to them :-).   Not elegant,
not the way I want to do it, but .. :(..

  I'm having a problem that my provider is unable to explain.  Let me
demonstrate by an example:

  from 207.141.254.20:  lynx www.sarc.msstate.edu

	The connection will be immediate, but it will be 2 minutes before
	any data is transferred back.  telnet/ftp will send the prompt back
	immediately (we're only 7 hops apart afterall).

  from outside of 207.141.254.:  lynx www.sarc.msstate.edu

	no slowness problem.

  from 207.141.254.20:  ftp ftp.netbsd.org

	10 seconds until the first prompt.

  from outside of 207.141.254.:  ftp ftp.netbsd.org

	3 seconds.

  See the pattern here?  Note that this applies to all 207.141.254.
machines.  Can somebody tell me where to even start
tracking down the problem?  If it's a reverse DNS lookup problem, is
there any utilities/commands that I can run to verify?  My provider is
handling my primary DNS, by the way.

  Thanks!

frontpage.rtr.com supports the unix extensions.  Micro(censored)
points people to that site when  you try and get the unix extensions.

Note: There are no "FreeBSD" extensions.  However, the BDSI ones 
are working quite nicely here.  (Complements and gratitudes to the FreeBSD
team for making BSDI compatibility work so well!).

I perpetuated the rumor, but I didn't start it.  Consider it quashed,
at least from me.

Isn't this considered a bugfix, not an "upgrade"?

In any case, it seems that it's not a very good idea to calculate
the price of Annex hardware without including the cost of a "software
upgrade contract" in the total when comparing them to their competition.

Sorry if I was a bit harsh, but my blood boils whenever I think of these
people.  I would call it a bugfix, but the coincidence here is that it is
fixed in the newer release (supposedly), so their opinion is "Hey, go buy
the new release; you get more features *and* bugfixes"...  Go to their
page sometime and look at release notes; they are funny.  In
9.2.something, you can crash an annex by fingering it....  Nice.

The simple thing to do is just to not buy their product.  It is merely
"OK" at best, and a nightmare on a bad day.  One klunky 486 and 72 ports
seems to be a bit of a stretch.

MS has finally gotten their head out of their ass and designed the extensions
so they aren't a screaming security breach (you don't need to run it as root
and you don't have to make all the files writable by the server daemon). 
However, be aware that you'll probably have to hack on their install script
to make it work.  Also, you apparently need to install DES, replacing MD5 for
encryption.  Of course, this means your password files are invalid and you'd
need to chpasswd every account.

Heh?  Why?!?

Unless you're running an ancient release of FreeBSD, installing DES
doesn't invalidate the MD5 passwords.  The system can still recognise
and validate the MD5 ones, it just gains the ability to do DES *also*
when you load the secure distribution.

Not true if you run > 2.1.5.  The libdescrypt library understands $1$ 
type salts and applies MD5, defaulting to DES if it is not given a salt 
which starts with $1$.

Check the length of the shared secret.  As I recall the Livingston code,
a secret length >15 chars will overwrite memory and is NOT checked.
Dunno if this is your problem, but in my working life I've seen the
code run on HP-UX and Irix and Unixware without much trauma.  It's not
sysv-specific, though.

Thanks for the indepth discussion of the Annex problems folks. It has
been a valuable exercise for me. While the Annex would seem to be fine 
for internal work, and has been ok up until the recent advancements
in software from various vendors, it now seems that it has reached its
limits in the Internet world. This it seems is due in large part to the
policies of the Annex manufacturers. If the thing cant be upgraded, at 
least for nominal cost, then it may as well be a small boat anchor.
I certainly wont be buying another one.

The probelm is compounded down under. The US company doesn't want to know
about anyone outside North America, specifically the US, and the Australian
company, and distributors simply don't reply to email, and plead insanity
when called direct! The usual "We'll look into it and get back to you"


So, does anyone know of a _good_ annex type device that will do the same job?
8 port, Rj45, Ethernet-UTP and can handle auto-dialing to
connect to the provider, .....and most of all :-) speaks rfc1323.


Thanks again folks.
Cheers
Robert

I thought total controls server just modems and not term server+modem

I am using the radius from ports, on a 2.1.6-Release box, with a USR Total
Control system.  I have not had the problems you describe.  You might want
to check the logfile to see if it tells why radius crashed.

Today an New York based ISP spammed our entire customer base. The
culprits are:"
Easyway Communications,Inc.
(www.easyway.net)

I sent them a bill for the delivery of the mail (which I'm sure they will ignore)
a) what more can I do?
b) is it possible for us to treat such people by collectively routing

Livinsgston's Portmaster 2e-10 has 10 ports, 10baseT Ethernet and can
autodial to the provider. I don't know about RFC1323 but if you send email
to megazone@livingston.com to ask about it he should know because he used
to be Xylogic's top tech support guy until about a year and a half ago so
he knows both product lines intimately.

grep -v usually works wonders for me.

MP=`mount -t ufs | sed 's;/dev/;&r;' | egrep -v ' on /news| on /nov ' | awk '{ print $3 }'`

find ${SRCHPATHS} \! -fstype local -prune -or -print | \
	egrep -v '^/news|^/nov' | \

etc.

It ain't artsy, but it works.

Incidentally: the latter find still traverses the spool.  I don't really
care.  I just didn't want it adding boatloads of bloat, I don't care too
much what disk I/O is like at 3AM.

Should be fine, except I would turn the 10 days into 7 if your going for
that number of groups.

Here are a few suggestions for dealing with such bozos:

  * Send a complaint to Sprint, who provides intenet access to these
    people. Maybe if enough people complain then Sprint might shut them
    down. 
       
  * Send both root and postmaster at easyway.net an email message asking
    them to stop spamming your site. Include the following paragraph:

      Spamming is a waste of my time and resources as well as being against
      the law. By Spamming my site you are in violation of US Code Title
      47. The following is a quote ...

          By US Code Title 47, Sec.227(a)(2)(B), a computer/modem/printer
          meet the definition of a telephone fax machine.  By
          Sec.227(b)(1)(C), it is unlawful to send any unsolicited
          advertisement to such equipment, punishable by action to recover
          actual monetary loss, or $500, whichever is greater, for each
          violation.    

  * Have your attorney draft and send a letter by registered mail to the
    State Attorney General and US Attorney General in you state. In this
    letter inform the attorney generals of this violation of federal law
    and ask them they plan on pursuing the case. If they are not going to
    pursue, why not. Make sure easyway.net also gets a copy of this letter
    by registered mail.

Nope. You can drop Mr. NetServer card into the chassis and then it becomes
term server. I've got it grouped with 48 digital modems... and no method
of authentication :)

/var/log/messages is claiming a sig 11 and core dump... Now my first thought
was 'bad memory chip', but this is the only application that will dump
period. And I've got plenty else running...

You can block access at the router level, with wrappers, or with filtering
in your freebsds.

Oh - we bought 12 of the modem pools, and each and every one has had to be
replaced - they would go all lights red, never to work again.

This isn't an isp question, but I thought the isps would
have the most information in this regard.

I am having a heck of a time isolating an intermittent problem on
a dedicated 56K line.  The thing just decides to drop carrier on
occasion.  Plug in a multitech and it works fine; plug in the
old unit and it works fine.  It may be in the dsu, so I am
looking for another one.  Can anyone recommend any good sources
for an adtran dsu5600 or equivalent?  Anyone have any recommendations
for a specific 56K dsu?

We were as close as signing a lease agreement to buy four of these, and
then USR's "devel team" told the salesperson they would have to charge
$7000 to compile their special Radius to run on FBSD, and they still
weren't sure if it could be set up with a menu so users could select ppp
or an rlogin into our shell machine.  It dragged on for 4 months with no
resolution, so we dropped it.  I even offered access to a machine here for
them to use for development and mentioned that lots of ISPs use FBSD,
Linux, etc.  They only support Solaris and NT (blech).

What did you end up with?  It seems that the Livingston PortMaster 3
works better than the Total Control, at less than half the cost (and
VERY inexpensive if all you need is ISDN).

Ours is working like a charm, anyway.

For a thousand, I could put together an old NCR or AT&T tank, with a bunch 
of full height 5.25" hard disks..  a few hundred for NT server...  and 
another thousand for a really good UPS.  The balance would be used to 
charter a plane.

You then fully charge the UPS, plug in the NT server, strap the contraption
securely together, and load the running pile of hardware on the plane.  You 
fly the plane way up high, and circle Microsoft headquarters in Washington,
waiting for a software crash.  (It is possible that the software won't
crash, and the batteries will start running low.  If so, stop waiting.)
Next, induce a hardware crash by pushing the contraption out of the door
of the plane.

With some luck, it might kill Bill.  :-)  ;-)

(Well, that's how _I_ would build a killer Windows/NT box)...

For the humor impaired... it's a JOKE...

access control lists blocking  port 25(smtp) from that domain would be
eaiser, if you have a router like a cisco or whatever, not a unix box.

Then you would SYN flood yourself. That is not a good idea. :)

If you want to throw packets from these people on the floor, just filter
their IPs on your border router with the Internet.

FreeBSD can do this, probably more easily than if you have a Cisco, if 
you have IPFIREWALL in the kernel.  But that does not solve the problem 
(can you say "multiple MX records"?)

-------- REPLY, End of original message --------

You may have allowed them to obtain most of your client's email 
addresses list by leaving in.fingerd in your inetd.conf file!

I suggest you:

A) "rem" it out of inetd.conf or
B) use tcpd and block access via /etc/hosts.deny to all but "trusted" 
   domains or.
C) Filter TCP port 79 at your router.

Remember the key question is: How did they get your client's addresses?
The Finger daemon is your most likely cause.

Try: finger @clari.net.au and see what you get.

If you are running in.fingerd with the -w command you are telling the 
whole world alot more than they need to know about your system.

[Cross-posted to security and questions twice over a period of 4 days, but 
never got a response.  Please accept my apologies in advance if you feel 
that either of *these* lists is inappropriate for these questions, but I do need 
answers.  Feel free to trim responses to the most appropriate group, I am 
subscribed to both.]

Howdy, :)

	I have been doing some research on the security of various *nix's, 
and found some very interesting discussion in the mail archives regarding 
the security of freebsd vs. a sequence number guessing IP spoof attack.  
Without rehashing what seemed to be a rather heated discussion last spring, 
I am wondering if someone could fill me in on any changes, improvements, 
etc. that have been made in 2.2 regarding this problem.  Also, if someone 
could highlight the changes regarding security against syn flooding 
promised in 2.2, it would help.  Of course, if this information is already 
available on line, a pointer to it would be appreciated.  

	And speaking of security, I am looking for information on the 
relative usefulness and efficiency of tcp wrappers vs. Darren Reed's IP 
filtering.  I've read all I can find on both (including downloading the IP 
filter package), and I'm still a bit confused about how much overhead either 
will add to my system.  It looks like I'll be going with Darren's stuff because 
I need to filter access to ircd, and as far as I can tell the wrappers won't 
hook it.  Any information or pointers to more detailed documentation would 
be appreciated.

Thank you,

Doug

This is FreeBSD. It is just fingerd. No in. prefix.

Rem? Isn't that a band? If one wants to turn off a service, one comments
it out with an # (hash).

I got the standard "must provide username". FreeBSD ships with the -s
option to fingerd enabled in inetd.conf.

Again, this is FreeBSD. There is no -w switch to fingerd. To learn
anything from fingerd as shipped in FreeBSD, one has to know the username
one is fingering. If you already have the username, you certainly don't
need finger to build a spam list now do you?

The easiest way to build a list is just call up and ask for a shell
account. Then use a little perl script to extract names from /etc/passwd.
Solution: Don't offer shell accounts. You will probably lose at least a
few customers if you do that. Whether the business lost is worth the added
costs of shell accounts is obviously a business decision.

Hello,

Email is working ok on my server.  I have one question/problem.  When
someone sends mail to a nonexistant address, I get the famous "config
error: mail loops back to me" error message.  Mail to/from valid addresses
work fine.  Is this normal?  Or, is there something in the config file that
needs tweaking?

Thanks,

There are many, none of which you want to do because of extreme security
problems (basically the CGI would hav to run as root, plus you would want
to run it under an SSL server).

BUT, if you insist upon this unsecure method, just have a cgi script
running as root which calls 'passwd' with the correct username and
password.  Course, piping into passwd may be hard, use perl, or write your
own 'passwd' program..

You're using a wildcard MX, right?  So if someone sends mail
to foobarola.wtrt.net, it ends up on your mail host.  But your
mail host tries to deliver to foobarola.wtrt.net, which doesn't
really exist, so it falls back to the wildcard MX, and tries
to deliver to itself, and barfs.

Solution:  Either lose the wildcard MX (my personal preference),
or make sendmail on your mail server strip off any host stuff
to the left of wtrt.net before processing, so that, e.g.,
"joebob@foobarola.wtrt.net" gets rewritten to "joebob@wtrt.net"
before it attempts delivery.

Probably easiest thing to do is to hack poppassd so that it understands 
an http request.

Yep.  You're right.  I did have a wildcard MX record.  Notice the past
tense.  It has been removed, and it fixed the problem.  I didn't need it,
not sure why I had it, but it's gone now.

   There were changes made that made the initial sequence number more random.
See rev 1.29 of tcp_input.c.
   The random drop syn-flood protection was implemented. See rev 1.52 of

Not necessarily. I wrote a CGI programme in my system which calls
yppasswdd to update the users' passwords. I do not have SSL running
yet but I can restrict the CGI to handle requests only from our dial-up
lines.

Ladies and Gentlemen,

This man either has too much time on his hands and isn't updating his 'how
to set up a screamin' deamon, newsfeed sucking and feeding, killer News

and is starting to become delirious in thinking that he can kill Bill.
After all Bill wouldn't be Bill if he was just Bill, therfore he must be

Is your badhost the same box?  I use mmdf mostly, but I believe you can
direct bad addresses to a baduser box (which is handy of you have some
users on 1 box, and some on another) - if that points back to the same box
it would get confused.

Hi All,

Well after all the comments about Annexes what do people recommend as a
terminal server for an ISP?. Looking for something expandable - starting
at 30 or so ports. Presumably support SLIP/CSLIP/PPP with authentication
on FreeBSD. Presumably they all will have ethernet of some form. How about
handling ISDN as well as analogue modems? AAny other helpful comments?

Someone told me Pormasters had a habit of spontaneous reboots. Anyone else
heard this?

Maybe they are running an old version of ComOS... We have several of them
and like them VERY much... Check out the PM3s from Livingston.. They handle
ISDN and analog quite well.... The other issue around reboots is memory.
If you are using a PM2E with an ISDN expansion card in it, you really
should upgrade the memory as Livingston reccomends.  Since we did that, we
havent had any reboots, and our dedicated lines have been staying connected
for over 70 days without a drop (the last time we rebooted it).  

Check out www.livingston.com, and have a read through the mailling archives
there.   I would say mostly happy customers.

Here is one of our boxes....

Livingston Enterprises PortMaster Version 3.3.1
System uptime is 196 days 9 hours 13 minutes

Also radius for Livingston (the ones who wrote it) runs quite well on
FreeBSD.  Have a look at the recent USR Total Control thread regarding
their version radius...

There's a bug or two in the beta software, but they've fixed it by
now.  I would highly recommend Livingston PM3s.. it may seem cheaper
to go with a bunch of analog modems, but you're setting yourself up
for problems, and will probably lose out in the long run to your
competition who did go the extra step.

Well for the best bet, a portmaster 3 works if you want dialup idsn
and normal analog modem connection.  Our PM2e and PM3 have not done
a spontanwous boot ever.  The problem with using a PM2 is that there
is alot of wireing for the 30 modems and the power supies.

If the 56k suff is a consern for you, then you will need something
that needs a pri, and the type of term servers take alot of cash.

Hi to the list,

Looking for used Cisco routers would consider AGS+/4.

That's all folks.

The script doesn't necessarily have to run as root.  The way we do it here is
the cgi contacts our POP Password server (written by Qualcomm) and lets it do
the password change.  This isn't any less secure than letting a user
telnet/ftp/pop3 into your server since the password is sent cleartext anyways.

Pardon the interruption, but I'm looking for some help.

We are adding a customer via direct ISDN.  We have a Livingston PM-2i, they
have an Ascend P50.  We are able to get packets to and from the 2i and p50
just fine.  Problem is, they run token ring and a windows NT server.  We
have installed an 10Base-T card in the server, and thought that we
configured routing correctly, but for some reason the server doesnt' want
to pass packets from the internal token-ring network to the p50 and then
out to us.  Each card has its own IP address, TCP is loaded.  The 10Base-T
card has the token ring card as the gateway and routing is turned on.  The
computer knows about both interfaces and seems to be happy with both of
them.

What else can we check or need to set.  Any ideas why this isn't working?

Thanks in advance.

Hallo,

we are running a very haevy loaded www-server (300.000 hits per day, 
45 MB data traffic per hour) on FreeBSD 2.2 (2.2 binaries, but 3.0 
kernel), AMD 133, 64 MB RAM, Apache 1.2.

The server has a lot of hits and especially amounts of CGIs running.

Few weeks ago I had to increase the number of process per user in 
the kernel, because the apache server could not spawn child processes for 
the CGIs. 

The only little problem is the increasing processor load between 0,8 
and 2.0, sometimes hihger.

For that reason I configured a new dual P5 with 2 x P5, 200 MHz 
(Gigabyte Board) with 3.0-972401-SNAP SMP. This is system has 
been running without any problem with about 50 virtual www servers and 
about 10 000 hits a day.

I changed the values in kernel tha same way also on the new server:
maxusers        100
options         CHILD_MAX=512
options         OPEN_MAX=512

Now, when I transfer the 300 000 hits server on this machine half of 
the CGIs can not be started. The error log of the server shows:
#--------
[Fri Jan 31 19:09:00 1997] access to /usr/home/pdecker/cgi/show_dat.pl
failed for c4.hrz.uni-giessen.de, reason: couldn't spawn child
process
#---------
The error log is full of theses messages.


What else can be the cause that the server cannot start the child 
processes?

I append the values of the kernel vriables to the end of this mail.

Thanks in advance

Richard

'routing' means ip-forwarding between the interfaces here ?

As I read it here you have the token ring card as default gateway for
the 10Base-T card?  It's supposed to be the other way around. On the
client it should read the server's token ring card ip-address as
gateway, and on the server it should read the Ascend's ip as default
gateway. If thee Ascend's ip is in the same range as the 10Base-T card
it will find it no problem.
If this won't solve your problem you should make a small drawing of your
configuration, and write the ip addresses and netmasks for each
interface.

- Rob.

Ok, here's our config:


Ascend				Server				Rest of Network
x.y.z.1			Enet Card	Token Ring		ip: .130-
255.255.255.128		x.y.z.10	x.y.z.129			|

|	|			|		|			|
|	|			|		|			|
|	-------------------------		-------------------------
|	  no hub, direct connect		       token ring hub
|
To PM2i

My drawing skills probably arent' the greatest, but hopefully this will
convey the point.  As I show in the diagram, we don't have a hub between
the server and P50, but the cable is good,  We have tested it with a laptop
and was able to telnet to the P50 and our network through the PM2i.  The
problem seems to be in the server.  We thought that it might be a problem
with the route table on the server, but there doesn't seem to be any docs
on how to change/delete bogus info from the NT server route table.

I posted my problem with our Web-Server that cannot spawn child 
processes.

Now, I tried to simulate the problem. In my tests I get the message
"too many open files".

But 
kern.maxfiles is 3240       

and 
kern.maxfilesperproc is 3240   too

Has anybody any Idea why the system cannot open more files (There are 
only a few processes running at the moment. There should not be more 
than max. 50 open files at this time.)

The system is a dual P5, 2 x P5 200MHz, FreeBSD 3.0-970124-SNAP SMP

Any help welcome!

Thanks in advance

Without getting into specifics, 300k/day on a web server with FreeBSD is 
nothing. 

We have boxes that are averaging over 40 million hits a day [average hit 
954bytes] without blinking. (over 50 conns/sec)

At command line do a "route ?" to add/delete/change route table on NT server and
workstation.  Their is also in 4.0 a rip capable router, that I am told will
take of all this for us.  I have not had a chance to give my NT server a second 
network card in 4.0, it did not work in 3.51.

   Wow! I think this is a stat we should remember. Would you be interested in
submitting something for the "FreeBSD Gallery"?

I've had alot of problems with 3.0 Snaps and allocating memory.  We tried
running a large volume news server on it and it crashed quite frequently.
You may want to try downgrading the OS & see if that fixes the problem,
of course, you'll be SMP'less but... It will run.

You can find wwwpass and poppassd at Chris Candreva's script page:
http://www.westnet.com/providers

wwwpass is at: http://www.westnet.com/providers/wwwpass.tar.gz
poppassd is at: http://www.westnet.com/providers/poppassd.tar.gz

Worked for me..  Although I remember poppassd not cooperating very well in the
beginning.

Best,

Yes.  Run 2.1.5 or higher.  Works fine, I believe.

Hmmm.  This is not my experience.  It instantly coredumps on 2.1.0-R(CD),
2.1.5, and 3.0-BETA.

Am I doing something wrong?

I have found that it was the perl binary that was causing core dumps when
I installed it on a 2.1.5 machine.  If you untar the file, replace the
perl program with one from FreeBSD, re-tar it, it should work fine.  I
have had it running this way on a 2.1.5 box and a 2.2-Beta box.

Thanks to all of you for your attention and responses!

Oh, dear.  I had tried the perl substitution on the 2.1.0-R box,
and that didn't work -- the Excite engines still bombed (even though
the netscape I use on the 2.1.0-R boxes is BSDI) so after that, I
used the perl as a "litmus test" for functionality.  It is now
clear that this was wrong.  The Excite engines *DO* run on 2.1.5
(and presumably later) even though the perl packaged with it does
not.  I was going to try it on my 3.0-BETA system, but it appears
I am have NFS problems with that system (old, slow 8-bit ethernet
card from the salvage heap)...

Do you think the person who sent in the original message is stupid? Or 
perhaps he is smart enough to realize that the "rem" quote was a figure 
of written speech and he really does know how to remove something from 
his inetd.conf.  Really, a # sign you say? Truly amazing->'Thanks Boy

And if he wasn't running fingerd with the -s? Does the -s option work? 
When did you last actually test it?  Not before before reading this 
reply!!!! If you had, judging by your "rem note" we would have all heard 
about it. Or do you actually believe there aren't any bugs in FreeBSD? 
But of course not, as we all know 2.1.6 didn't fix anything in 2.1.5 it 
was perfffffffffffect just like 1.0 

    A direct quote from the FreeBSD Man Page for Fingerd:

    If the line is null (i.e. just a <CRLF> is sent) then finger
    returns a ``default report" report that lists all people logged
    into the system at that moment.

By doing this several times over a period of days logging the results (a 
cron perl script, logging to a file) do you think they would be able to 
get list of users??

Right!!!!! Call Australia from New York and ask for a dial-up shell 
account. 

"Hi my name is junkmail from easyway.net and I'm calling from New York. 
I would like to apply for a dial-up shell account. 

Consider the reply "sorry but we don't offer shell accounts." ->'How now 
brown cow'?

And as we all know there's only a "few hundred thousand dial-up ip 
providers in the world, so this won;t cost too much if they all say 
yes". Besides why would anyone ever question some one from New York 
wanting a dial-up account in Australia, Japan, Hong Kong, Korea, etc. 

But Hey You Could Try This->'The dial-up service here is so bad and I 
get lots of free air miles credits from my long distance phone company. 
Do you have air miles?' Maybe it will work.

Plus giving out shell accounts isn't bad, since everyone is so honest 
what possible harm could it cause? Why I just can't wait to sign up 
more. That extra $10 a month is worth it

Hey, it never hurts to be clear when one is writing. When one is talking
about technical subjects, it's best not to use figures of speech. Don't
you agree Batman? :-)

Yes, the -s option works. That was fixed over a year ago (including in
2.1.5).

Which is diabled with the -s option.

Why not? I have a definite use for accounts at different points in the
network to test connectivity, etc. Of course, the proliferation of
traceroute gateways on Web pages is changing this.

As I said, it's a business decision.


Now, lest you patient readers think this message is a total waste of your 
time, I have a question. Is anyone hosting a Quake server using FreeBSD?
If so, how do you start it at boot? It seems to want to hang onto the tty.
Also, is it possible to buy the registered DOS version and somehow use it
so that players get all the levels?

I know somebody who did this every 5 minutes for three months including
a script to summarize the user list so he could keep track of the
competitor's growth. The reason he stopped was that he discovered that 
he could just tftp the /etc/passwd file from the competitor's SCO system.

It is possible to configure a shell machine so that the /etc/passwd file
does not contain usernames, only the userid numbers. This is especially
easy with FreeBSD where you have the complete source. Just change every
mention of /etc/passwd to /.etc/.passwd and then modify adduser to keep a
bogus /etc/passwd file in place for when you forget to modify a package
that you install. There are probably a dozen other ways to secure a shell
machine.

I am still trying out schemes to change passwords via a web page.

Most solutions that people have suggested seem to use poppassd.

I have compiled the port of v1.2 under FreeBSD 2.2-BETA but can't get it 
to behave.

It gets to the point where it asks for a new password which I submit via the
newpass <password> string but poppassd then returns

500 Unable to change password.

Noting other than a failed attempt gets entered into it's log.

Obviously other people have gotten the thing to run so it must be my
configuration.

Does poppassd require any special support programs, libraries, or kernel 
options for it to work? 

Or is there a better ISP quality password change daemon around?

- Ernie.

Sender: owner-isp@FreeBSD.org

Hi Guys!

First I'd like to say thanx to those that helped last time; sorry for my
tardy response.

I've installed FreeBSD and am being driven crazy by sliplogin; I've read the
man pages, FAQ's and doc's; tried lots of stuff, and I can not determine the
problem.

>The server answers and runs sliplogin, but any packets sent just idle to
nowhere; and, after 30 or so seconds, it drops the line.  Incidently,
>running slirp after logging in as a regular user gives no probs.

The problem has shifted:  I removed the arp lines in slipup and slipdown.
Now, upon establishing a connection, I can ping the world, dig, ftp, surf,
anything, for about 2 min 57 sec!  Then, even if in the middle of an ftp
transfer, poof, 0 communication, I can't even see a host on my own net, not
even the oher side of the slip.


Joe provided me with the following:

># sysctl -w net.inet.ip.forwarding=1
this was already done (kernel re-compiled)

># cd /etc/sliphome
># cat slip.hosts
>Saccount          206.55.68.1     206.55.68.2     0xfffffff8 autocomp
already done, with .17 and .18 (subnet of my class C)

># grep Saccount /etc/passwd
>Saccount:*:1000:66:Some Co. Inc.  SLIP:/etc/sliphome:/usr/local/sbin/sliplogin
already done, with group 69 (slip), login shell changed per above, (formerly
/usr/sbin/sliplogin)

and created:

># cat /usr/local/sbin/sliplogin
>#! /bin/sh -
>
>PATH=/bin:/usr/bin:/usr/local/bin; export PATH
>
>stty crtscts
>
>mesg n

done, I added the script.

my statement:
>The server answers and runs sliplogin, but any packets sent just idle to
nowhere; and, after 30 or so seconds, it drops the line.  Incidently,
>running slirp after logging in as a regular user gives no probs.
                (was incorrect, the problem manifests itself later (see below))
 prompted Danny to reply:
>What do you get if you do ifconfig sl0?  Is the interface correctly

I think so. Yes cslip at both ends. ifconfig is as follows:

Oh, Thank You, it would be most appreciated.

it is an internal modem, no lights, (I'm really in the dark :-)

Tumpet Winsock, ver 2 & 3; checking some others, too; yes I can & have
checked it.
Above log from ver 3; when I use ver 2, it does not timeout, but I can not
ping any machine, on or off my network

Basically, I have one class C address, subnetted as 255.255.255.248 (3 bit
hosts);

<mach a> --- <mach b> --- <main unix box > --- <mach c> --- <mach d>
: ethernet
                                                   |                   L---

                                                 <modem>

The (multihomed) main box has:  ed1 with ip .2 directly connected to the
router (pipeline) ip .1 via 10baseT (no concentrator)
                                                              ed0 with ip
.12 connected to the other machines (.9 thru .14) via bnc (rb58)
                                                              sl0 with ip
.17 (hopefully connecting to .18), 14,4 modem
I have repeated all tests with the modem on machine B (ip .11) keeping sl0
with ip .17; I've also tried two 2400 (genuine hayes), another 14,4 and a 57,6

The object is to allow several users to use trumpet winsock w/netscape.  I
have tried ppp, but have even more probs; ideally I'd like both to work.

Any ideas, or any sources of info will be met with great appreciation;  I
have read several books on unix and tcp/ip and bbs's; and the postings from
other FreeBSD newsgroups;

Thanks in advance,

Steve

Are you or the other end running routed or gated?  A three minute timeout 
sounds like a RIP expiry time.

If you are running gated or routed the sl* interfaces must be marked as 
passive, i.e. don't expect information from the remote gateway, just assume 
they are working.  Otherwise, gated/routed will expect the other end to 
continually annouce its presence, and if it doesn't, the route will be 
marked for deletion after 1 minute silence and deleted after a further 
two minutes of silence.
