I'm looking for a way to establish a _secure_ NFS connection in a WAN / Internet environment. I know NFS is not secure from this point of view, so I would ask if someone have a solution. Encapsulating over SSH is not easy with all the different ports needed by NFS, so what I could do ? Maybe running it over something like IPSec, VPNs, etc. ? Better alternatives ?

Tony, Actually, it turned out to be a little more subtle. The DOMAIN(generic) directive includes /usr/share/sendmail/cf/generic.m4, which has the line EXPOSED_USER(`root'), which was the exact cause of the error I was getting. I copied generic.m4 to int.m4, commented the offending line, changed kanga.int.mc to read DOMAIN(int), and everything was fixed. -- Kirk Strauser To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Sun Aug 5 19: 5:20 2001 Delivered-To: freebsd-net@freebsd.org Received: from firewall.crimsonwasteland.com (cx154799-b.btnrug1.la.home.com [24.181.119.107]) by hub.freebsd.org (Postfix) with SMTP id 2DC2337B403 for ; Sun, 5 Aug 2001 19:05:16 -0700 (PDT) (envelope-from lists-freebsd-net@crimsonwasteland.com) Received: (qmail 1342 invoked from network); 5 Aug 2001 21:02:19 -0000 Received: from travis.crimsonwasteland.com (HELO travis) (172.16.69.2) by cx154799-b.btnrug1.la.home.com with SMTP; 5 Aug 2001 21:02:19 -0000 From: "Travis Leuthauser" To: Subject: IPSec Question Date: Sun, 5 Aug 2001 21:05:14 -0500 Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 (Normal) X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook IMO, Build 9.0.2416 (9.0.2911.0) Importance: Normal X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4522.1200 Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I'm trying to setup a tunnel between a FreeBSD 4.4 Prerelease box and a Netopia R9100 dual ethernet router.

Per the dictionary definition of cache, perhaps, but 'cache' means something very different to those of us in router land. A cache based router (think 75xx Cisco _WITHOUT_ CEF), when a packet comes in for a route that has not been used the cache misses, the packet is punted to a general purpose CPU, the lookup done, and a cache entry installed on a linecard. Cache memories were limited, and were as such aged. This scheme had a number of problems: 1) High first packet penality of a flow. 2) The number of flows could exceed available cache memory. 3) The aging process hammered the box. 4) The aging process often removed active flows, causing a first packet penality mid-flow, sometimes causing TCP events (eg backoff). This became a larger problem day by day, as a larger percentage of the routing entries were sitting in the cache. So, router vendors went with cache-free designs. In a cache free design there is the RIB - Routing Information Base which contains routes the way routing protocols see them (eg, destination foo is in bgp which has a next hop in ospf which has a next hop out a connected interface), there are many levels of indirection there so recalculations can be done. At various checkpoints (typically after each protocol does a recalculation) the router builds the FIB - Forwarding Information base. This takes all the levels of indirection, and boils them down to where the packet goes (desination to connected interface). This table as such is smaller, and only ever requires a single lookup to know where to send a packet. The new routing designs then use the FIB (distributed to the linecards on the Cisco GSR and 7500 with CEF, kept on a central forwarding engine on the Juniper M-series). The important thing to note (which makes it not a cache in my book) is that it is th full table, need it or not, there can be no "miss" for an active route. Back to the original topic, small UDP packets from a DNS server. In the caching routers, each packet would generate a cache entry, which 95% of the time would never be used again before it was aged. The adding and removing of entries hammered the routers. Newer routers always have all entries in the FIB, so there is no penality for throwing packets at the box that go in different directions, or that go once and are never seen from again. So, if you want to call it a cache, that's fine. If you say that to a router jockey, you're going to give them the impression you're talking about the first setup though, which I don't think is what you want. -- Leo Bicknell - bicknell@ufp.org Systems Engineer - Internetworking Engineer - CCIE 3440 Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Mon Aug 6 8:35: 6 2001 Delivered-To: freebsd-net@freebsd.org Received: from khavrinen.lcs.mit.edu (khavrinen.lcs.mit.edu [18.24.4.193]) by hub.freebsd.org (Postfix) with ESMTP id 70D8637B403 for ; Mon, 6 Aug 2001 08:35:02 -0700 (PDT) (envelope-from wollman@khavrinen.lcs.mit.edu) Received: (from wollman@localhost) by khavrinen.lcs.mit.edu (8.11.4/8.11.4) id f76FYi949671; Mon, 6 Aug 2001 11:34:44 -0400 (EDT) (envelope-from wollman) Date: Mon, 6 Aug 2001 11:34:44 -0400 (EDT) From: Garrett Wollman Message-Id: <200108061534.f76FYi949671@khavrinen.lcs.mit.edu> To: Kirk Strauser Cc: freebsd-net@FreeBSD.ORG Subject: Can't get sendmail to masquerade In-Reply-To: <874rrm1e9p.fsf@pooh.int> References: <874rrm1e9p.fsf@pooh.int> Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org < said: > I'm using sendmail 8.11.5 on a FreeBSD-STABLE (4.4-PRERELEASE) system.

Ok, what I am trying to do is to follow the example on the ng_one2many man page to create a network interface that will aggregate across my dc0 and dc1 interfaces. No where in the page does it show you having to setup the other netgraph nodes (which I was suspecting was the case). So a shot at this I would need to create some iface nodes called dc0, dc1 and trnk0? I do not know what the 'upper' node would be though. - JimP -- --- @(#) $Id: dot.signature,v 1.10 2001/05/17 23:38:49 Jim.Pirzyk Exp $ __o Jim.Pirzyk@disney.com ------------- pirzyk@freebsd.org _'\<,_ Senior Systems Engineer, Walt Disney Feature Animation (*)/ (*) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Mon Aug 6 14:22:52 2001 Delivered-To: freebsd-net@freebsd.org Received: from InterJet.elischer.org (c421509-a.pinol1.sfba.home.com [24.7.86.9]) by hub.freebsd.org (Postfix) with ESMTP id 61B7E37B403 for ; Mon, 6 Aug 2001 14:22:50 -0700 (PDT) (envelope-from julian@elischer.org) Received: from localhost (localhost.elischer.org [127.0.0.1]) by InterJet.elischer.org (8.9.1a/8.9.1) with ESMTP id QAA66940; Mon, 6 Aug 2001 16:31:50 -0700 (PDT) Date: Mon, 6 Aug 2001 16:31:49 -0700 (PDT) From: Julian Elischer To: Jim Pirzyk Cc: freebsd-net@freebsd.org Subject: Re: ng_one2many usage In-Reply-To: <01080612513307.04774@snoopy> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org On Mon, 6 Aug 2001, Jim Pirzyk wrote: > > Ok, what I am trying to do is to follow the example on the > ng_one2many man page to create a network interface that will > aggregate across my dc0 and dc1 interfaces.

There are 1 total nodes: Name: ngctl17931 Type: socket ID: 0000000c Num hooks: 0 > if they support netgraph they will already be present. They are Intel 21143 10/110BaseTX chipsets on the motherboard of the Alpha DS10. I also do not see anything but the default netgraph on a Dell Dimension with the 3Com 3C90x chipset, nor do I see them on an Intergraph with the Inter EtherExpress Pro card (fxp0). Since they do not show up on the netgraph interfaces, I would assume then they are not supported. - JimP -- --- @(#) $Id: dot.signature,v 1.10 2001/05/17 23:38:49 Jim.Pirzyk Exp $ __o Jim.Pirzyk@disney.com ------------- pirzyk@freebsd.org _'\<,_ Senior Systems Engineer, Walt Disney Feature Animation (*)/ (*) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Mon Aug 6 15:23:59 2001 Delivered-To: freebsd-net@freebsd.org Received: from odin.ac.hmc.edu (Odin.AC.HMC.Edu [134.173.32.75]) by hub.freebsd.org (Postfix) with ESMTP id A36C037B405 for ; Mon, 6 Aug 2001 15:23:55 -0700 (PDT) (envelope-from brdavis@odin.ac.hmc.edu) Received: (from brdavis@localhost) by odin.ac.hmc.edu (8.11.0/8.11.0) id f76MNqd22250; Mon, 6 Aug 2001 15:23:52 -0700 Date: Mon, 6 Aug 2001 15:23:52 -0700 From: Brooks Davis To: Jim Pirzyk Cc: Julian Elischer , freebsd-net@FreeBSD.ORG Subject: Re: ng_one2many usage Message-ID: <20010806152352.A22092@Odin.AC.HMC.Edu> References: <0108061452500F.04774@snoopy> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-md5; protocol="application/pgp-signature"; boundary="pf9I7BMVVzbSWLtt" Content-Disposition: inline User-Agent: Mutt/1.2.5i In-Reply-To: <0108061452500F.04774@snoopy>; from Jim.Pirzyk@disney.com on Mon, Aug 06, 2001 at 02:52:50PM -0700 Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org --pf9I7BMVVzbSWLtt Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable On Mon, Aug 06, 2001 at 02:52:50PM -0700, Jim Pirzyk wrote: > Since they do not show up on the netgraph interfaces, I would=20 > assume then they are not supported.

Does anyone who is familiar with the problem and attack know if something like the following would be a useful temporary work-around? ipfw add 1 deny ip from any to any fragment Does the above drop the fragment and prevent reassembly buffer starvation? Of course dropping ALL fragments like that will limit the connectivity of the host to hosts and networks where fragmentation occurs. But, if the above DOES prevent the DOS, it may be a useful tradeoff to use it as a temporary work-around until kernels are patched (kernels with ipfw already enabled). Aaron out.

The only thing that sets F3 apart is the fact that any connection to it is done through a vlan interface. I have put tcpdump log on http://people.freebsd.org/~dcs/f3.log showing the problem. Host 172.31.199.19 is F3. I ssh'ed into it, cat'ed a file a couple of times, and, when it finally blocked, I ping'ed it. I then typed ^C a few times (just to send characters to the other side) from the client, ping'ed again, and then let the connection be resetted for timeout. There is one extraneous connection as I ssh'ed into it to get http://people.freebsd.org/~dcs/netstat.log, showing that the send buffer on the server side (F3) is full of stuff. Now... I cannot see how could vlans possibly interfere with the tcp stack. Any hints anyone? I can provide whatever logs and dumps you wish from the client side, but since I cannot copy any sizeably log from F3 itself... -- Daniel C.

The man page for accf_http states that: It prevents the application from receiving the connected descriptor via accept() until either a full HTTP/1.0 or HTTP/1.1 HEAD or GET request has been buffered by the kernel. What seems to be happening is Code Red II sends its 3.8K malformed request, but the accept filter doesn't recognize this request as being completed. So the connection sits in the established state with 3818 bytes in the Receive Queue as shown in the following netstat: Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 3818 0 10.1.1.1.80 64.1.1.1.2932 ESTABLISHED If you get enough of these (about 20-30 on a machine with NMBCLUSTERS set to 1024), your mbuf cluster pool becomes exhausted and network transactions begin to fail. This inadvertent side affect of the Code Red worm suggests that it would also be relatively easy to launch a denial of service attack against a machine with HTTP accept filtering.

This is somewhat true, however your machine seems to be configured quite poorly.

Yes, I agree that this machine was configured poorly to be a production web server. However, this machine was just used for testing and if it wasn't for Code Red scans would have practically no http traffic. I realize that most people would not be running accept filters on a low traffic test machine, but regardless, I though a mention of the problem would be warranted in case anyone else ran into this problem and was unsure of the cause.

Why not 1500 ? Per RFC2460: "IPv6 requires that every link in the internet have an MTU of 1280 octets or greater. On any link that cannot convey a 1280-octet packet in one piece, link-specific fragmentation and reassembly must be provided at a layer below IPv6. Links that have a configurable MTU (for example, PPP links [RFC1661]) must be configured to have an MTU of at least 1280 octets; it is recommended that they be configured with an MTU of 1500 octets or greater, to accommodate possible encapsulations (i.e., tunneling) without incurring IPv6-layer fragmentation." Actually I am wondering about it now myself. X.25 is one of the few link layer protocols left which has a MTU < 1500 (aside from 802.3's 1492).

What I understand is that using a MTU of 1280 guarantees no IPv6 fragmentation since it is the minimum supported. Of course, if a link cannot accomodate the MTU it must fragment at a layer below the IPv6 layer, but it will not be fragmented on the IPv6 layer itself. Of course, like the RFC says: "[...]; it is recommended that they be configured with an MTU of 1500 octets or greater, to accommodate possible encapsulations (i.e., tunneling) without incurring IPv6-layer fragmentation." So it seems that the IPv6 fragmenting is causing problems of some sort.

Why not 1500 ? It can't be 1500 because the tunneling protocol is designed to use an MTU which insures that packets don't get fragmented (except in one weird edge case.) Since there is a wrapping IP header, the MTU of an IP over IP tunnel can be no more then 1480 in the common case. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.

Hi,

Is there anyone know any software which can catch all the packets over the network (like tcpdump) and replay selectived ones to the network again? I hopet there is some hacking tool can do these on freebsd.

Hope someone can help me out, thanks in advance!

(therefore, gif MTU should better be statically defined) as others noted, if you set gif MTU to 1500, then you will see a lot of fragmented packet exchanges (= poor performance). if you use IPv4 as the outer header, MTU <= 1480 avoids fragmentation and more performant. as 1280 <= 1480, we avoid fragmentation with the current default configuration. itojun To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Wed Aug 8 12:58:22 2001 Delivered-To: freebsd-net@freebsd.org Received: from smtp1.sentex.ca (smtp1.sentex.ca [199.212.134.4]) by hub.freebsd.org (Postfix) with ESMTP id 5693B37B411 for ; Wed, 8 Aug 2001 12:58:13 -0700 (PDT) (envelope-from mike@sentex.net) Received: from simoeon.sentex.net (pyroxene.sentex.ca [199.212.134.18]) by smtp1.sentex.ca (8.11.2/8.11.1) with ESMTP id f78Jw3688741; Wed, 8 Aug 2001 15:58:03 -0400 (EDT) (envelope-from mike@sentex.net) Message-Id: <5.1.0.14.0.20010808155054.04d25380@marble.sentex.ca> X-Sender: mdtpop@marble.sentex.ca X-Mailer: QUALCOMM Windows Eudora Version 5.1 Date: Wed, 08 Aug 2001 15:51:49 -0400 To: Jun-ichiro itojun Hagino , Jeroen Ruigrok/Asmodai From: Mike Tancsa Subject: Re: gif MTU of 1280 ?

Yeah, configure your own DNS server and ignore theirs. At the very least, configure a cache-only DNS server or a forwarding DNS server. The O'Reilly books on "TCP/IP Network Administration" and "DNS and BIND" will be very helpful to you. Start with the TCP/IP book and buy the DNS book when you run out of help in the other one. -- "Where am I, and what am I doing in this handbasket?"

Nslookup is a client, which really has little to do with your nameserver (apart from sending queries to it), so what you see with nslookup isn't necessarily what other people see. And nslookup actually uses a custom resolver library that isn't the same as would be used by "normal" clients. There are many tools, such as dig, which will give you a much better idea of what's going on.

After some time the administrator deletes one of the prefixes and the future router advertisement will carry only one prefix. What will hosts do with the deleted prefix? Whether the addresses will be deleted after some time? What is this time? From the specs i found that the addresses are deleted only if the router advertises prefix with valid life time of zero. Whether the rtadvd daemon has to send any such message with deleted prefix life time set to zero? I feel that the addresses should be deleted immediately if a router stops advertising the prefix. regards ravi prasad. __________________________________________________________________ Your favorite stores, helpful shopping tools and great gift ideas.

We have tried to track down the problem and it seems to be a bug or a feature in gas or libbfd. It turns out, that the output from pxeldr before the binutils-2.11 import on 5/29/2001 was 500 bytes long. After the import the output has grown to 512 byte. The excess bytes contain a jump to the address 512 and a number of NOPs. The result of this is, that the loader image which is located imediately after pxeldr is shifted by 12 bytes and the address calculations in pxeldr.s are wrong now. Unfortunately we're not able to find out what new bug^h^h^hfeature of gas or libbfd causes this behaviour. A simple workaround is to strip the excess bytes from pxeldr just before building pxeboot, but that is REALLY ugly: Index: Makefile =================================================================== RCS file: /usr/ncvs/src/sys/boot/i386/pxeldr/Makefile,v retrieving revision 1.6 diff -r1.6 Makefile 36c36,37 < objcopy -S -O binary ${LDR}.out ${.TARGET} --- > objcopy -S -O binary ${LDR}.out ${LDR}.tmp > dd if=${LDR}.tmp of=${.TARGET} bs=500 count=1 regards falco & harti > Date: Tue, 17 Jul 2001 12:44:10 +0200 > From: Falco Krepel > To: net@FreeBSD.ORG > Subject: pxeboot doesn't work anymore > > I use the 3COM 3C905c TX-M with bootrom (PXE v2.20, MBA v4.30).

Yes, it would be evil to let an external node flood a subnet with broadcast traffic. However, there are legitimate uses for it. For instance, hosts in a DMZ may wish to broadcast snmp traps to hosts in the secure network. ipfw and ipf provide excellent ways to enable broadcast forwarding while preventing broadcast flood attempts. As for the external subnet, freebsd lets it pass because it isn't technically a broadcast till it reaches the last router. One more thing, -CURRENT will stuff two copies of any broadcast into bpf, it seems. tcpdump shows two packets being sent for every broadcast, and in actualilty only one is sent. I might look at this when I get some time -- unless someone else wants to take a shot at this. -Jon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Thu Aug 9 9:21:11 2001 Delivered-To: freebsd-net@freebsd.org Received: from beppo.feral.com (beppo.feral.com [192.67.166.79]) by hub.freebsd.org (Postfix) with ESMTP id 4B2E537B401; Thu, 9 Aug 2001 09:21:02 -0700 (PDT) (envelope-from mjacob@feral.com) Received: from wonky.feral.com (wonky.feral.com [192.67.166.7]) by beppo.feral.com (8.11.3/8.11.3) with ESMTP id f79GKxI16455; Thu, 9 Aug 2001 09:20:59 -0700 (PDT) (envelope-from mjacob@feral.com) Date: Thu, 9 Aug 2001 09:20:55 -0700 (PDT) From: Matthew Jacob Reply-To: To: Jonathan Chen Cc: , Subject: Re: forwarding broadcast In-Reply-To: <20010809113638.A9519@enterprise.spock.org> Message-ID: <20010809092010.M69994-100000@wonky.feral.com> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I haven't consulted the RFCs either, but, ahem, I thought this was a major point of netmasks and routers and why multicast was invented- to keep broadcasts from clogging the world. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Thu Aug 9 9:24: 3 2001 Delivered-To: freebsd-net@freebsd.org Received: from bilver.wjv.com (dhcp-1-3.n01.orldfl01.us.ra.verio.net [157.238.210.3]) by hub.freebsd.org (Postfix) with ESMTP id 11FC137B401; Thu, 9 Aug 2001 09:23:54 -0700 (PDT) (envelope-from bill@bilver.wjv.com) Received: (from bill@localhost) by bilver.wjv.com (8.11.1/8.11.1) id f79GNrr32952; Thu, 9 Aug 2001 12:23:53 -0400 (EDT) (envelope-from bill) Date: Thu, 9 Aug 2001 12:23:52 -0400 From: Bill Vermillion To: Jonathan Chen Cc: net@FreeBSD.ORG, hackers@FreeBSD.ORG Subject: Re: forwarding broadcast Message-ID: <20010809122352.B32613@wjv.com> Reply-To: bv@wjv.com References: <20010809113638.A9519@enterprise.spock.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i In-Reply-To: <20010809113638.A9519@enterprise.spock.org>; from jon@FreeBSD.ORG on Thu, Aug 09, 2001 at 11:36:38AM -0400 Organization: W.J.Vermillion / Orlando - Winter Park Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org On Thu, Aug 09, 2001 at 11:36:38AM -0400, Jonathan Chen thus sprach: > On FreeBSD -CURRENT and -STABLE, packets to broadcast addresses > are not forwarded.

More general forwarding of broadcasts is impossible without an appropriate routing protocol; all such protocols currently in existence are targeted at multicast, and not broadcast, since multicast is the correct, officially-sanctioned way to make such transmissions. (You'll note that multicast is a mandatory element of IPv6; IPv6's analogue to ARP uses it instead of interrupting every machine on the network.) -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Thu Aug 9 9:27:43 2001 Delivered-To: freebsd-net@freebsd.org Received: from enterprise.spock.org (cm-24-29-85-81.nycap.rr.com [24.29.85.81]) by hub.freebsd.org (Postfix) with ESMTP id 3FD2437B407; Thu, 9 Aug 2001 09:27:39 -0700 (PDT) (envelope-from jon@enterprise.spock.org) Received: (from jon@localhost) by enterprise.spock.org serial EF600Q3T-B7F; Thu, 9 Aug 2001 12:27:10 -0400 (EDT) (envelope-from jon)$ Date: Thu, 9 Aug 2001 12:27:10 -0400 From: Jonathan Chen To: Matthew Jacob Cc: net@FreeBSD.ORG, hackers@FreeBSD.ORG Subject: Re: forwarding broadcast Message-ID: <20010809122710.F9519@enterprise.spock.org> References: <20010809113638.A9519@enterprise.spock.org> <20010809092010.M69994-100000@wonky.feral.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: telnet/1.1x In-Reply-To: <20010809092010.M69994-100000@wonky.feral.com>; from mjacob@feral.com on Thu, Aug 09, 2001 at 09:20:55AM -0700 Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org On Thu, Aug 09, 2001 at 09:20:55AM -0700, Matthew Jacob wrote: > > I haven't consulted the RFCs either, but, ahem, I thought this was a major > point of netmasks and routers and why multicast was invented- to keep > broadcasts from clogging the world. It would be nice if all applications supported multicast. It would be even nicer if I could figure out why mrouted isn't doing what it's supposed to do on this machine, but that's a whole different problem... I might ask for help on that one if I still can't figure it out after some debugging... -Jon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Thu Aug 9 9:31:14 2001 Delivered-To: freebsd-net@freebsd.org Received: from enterprise.spock.org (cm-24-29-85-81.nycap.rr.com [24.29.85.81]) by hub.freebsd.org (Postfix) with ESMTP id A4C1637B406; Thu, 9 Aug 2001 09:31:08 -0700 (PDT) (envelope-from jon@enterprise.spock.org) Received: (from jon@localhost) by enterprise.spock.org serial EF600Q3T-B7F; Thu, 9 Aug 2001 12:30:56 -0400 (EDT) (envelope-from jon)$ Date: Thu, 9 Aug 2001 12:30:56 -0400 From: Jonathan Chen To: bv@wjv.com Cc: net@FreeBSD.ORG, hackers@FreeBSD.ORG Subject: Re: forwarding broadcast Message-ID: <20010809123056.G9519@enterprise.spock.org> References: <20010809113638.A9519@enterprise.spock.org> <20010809122352.B32613@wjv.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: telnet/1.1x In-Reply-To: <20010809122352.B32613@wjv.com>; from bill@wjv.com on Thu, Aug 09, 2001 at 12:23:52PM -0400 Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org On Thu, Aug 09, 2001 at 12:23:52PM -0400, Bill Vermillion wrote: > On Thu, Aug 09, 2001 at 11:36:38AM -0400, Jonathan Chen thus sprach: > > > On FreeBSD -CURRENT and -STABLE, packets to broadcast addresses > > are not forwarded.

I'm pretty sure my setup is correct here. So they are two separate networks therefore a broadcast for one should not go the other. If on the other hand you netmask was 255.255.252.0 then 192.168.0.x thru 192.168.3.255 would be part of the same network and you'd expect a broadcast to propagate.

In plain english and without the use of confusing IP/netmasks: A machine connected to interface 0 of the router is sending a unicast ethernet packet (directed to interface 0 of the router) to the ip broadcast address of interface 1. It used to be that routers were expected to go ahead and broadcast the same ip packet on network 1, but a recently updated standard changed the requirements so it is no longer true. Of course, broadcasts from a machine on interface 0 to the ip broadcast address of network 0 is not expected to appear on network 1... -Jon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Thu Aug 9 10:27:17 2001 Delivered-To: freebsd-net@freebsd.org Received: from amc.isi.edu (amc.isi.edu [128.9.160.102]) by hub.freebsd.org (Postfix) with ESMTP id 9D85B37B405; Thu, 9 Aug 2001 10:27:06 -0700 (PDT) (envelope-from yushunwa@amc.isi.edu) Received: from localhost (yushunwa@localhost) by amc.isi.edu (8.11.1/8.11.1) with ESMTP id f79HR5n42812; Thu, 9 Aug 2001 10:27:06 -0700 (PDT) (envelope-from yushunwa@amc.isi.edu) Date: Thu, 9 Aug 2001 10:27:05 -0700 (PDT) From: Yu-Shun Wang To: Jonathan Chen Cc: , Subject: Re: forwarding broadcast In-Reply-To: <20010809113638.A9519@enterprise.spock.org> Message-ID: <20010809102555.Y42772-100000@amc.isi.edu> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Hi, I think it's specified in RFC 2644.

Looks like it is aligning the end of the text even though I haven't asked. A grotty hack would be to use a org at the end to force pxeldr to be 512 bytes.

I've recompiled FreeBSD to include the ti driver but have been unsuccessful in setting it to Half-Duplex. I'm currently getting info from a fiber tap which only sends and cannot recieve. When it enters full-duplex mode the software I'm using shuts down due to the lack of establishing link. The ti man page says see ifconfig. Ifconfig says its a driver setting. Rc.conf has been no help either. Has anyone here dealt with the same problem? Any help is immensely appreciated.

I believe RFC 2644 actually suggested that routers MUST default to disabling directed broadcast except explicitly configured to do so. But I guess one can never be too careful. :-) yushun. ____________________________________________________________________________ Yu-Shun Wang Information Sciences Institute University of Southern California On Thu, 9 Aug 2001, Warner Losh wrote: > In message <20010809102555.Y42772-100000@amc.isi.edu> Yu-Shun Wang writes: > : I think it's specified in RFC 2644.

I've found some instructions on the web on how to setup the PPPoE server and so far I've managed to make it run. We are using the RADIUS server of our upstream ISP for authenticating clients. Here's a copy of my /etc/ppp/ppp.conf: pppoe-in: allow users enable pap allow mode direct set mru 1460 set mtu 1460 set speed sync enable lqr accept dns set ifaddr 202.91.163.1 202.91.163.20-202.91.163.50 set dns 202.91.161.130 202.47.132.1 load server set radius /etc/ppp/radius.conf set log phase ipcp lcp debug Their RADIUS server sends a reply for Framed-IP-Address: 255.255.255.254 and Framed-IP-Netmask: 255.255.255.0 But upon inspection of the client, it shows that it got the 255.255.255.254 address instead of the IP address pool as defined in ppp.conf. What else could be wrong here? Where should I look?

Thanks go to Barney and Julian for suggesting these changes. I've done extensive testing with this patch, and all sysctls controlling its operation appear to work properly. However, testing would still be very helpful. I'll be on vacation from the 12th through the 19th; if no problems have been found during that time I expected to commit and MFC it on the 21st.

However, there are lots of ready-made utilities out there that I do not want to modify the source for, I just do not want them to use IPv6 addresses for the present. As I said, most of them already can do this with a command-line option, but it seems that there is no program-independent way to tell the resolver libraries to do it. > > getaddrinfo(3) have an IPv4-only command-line option, but is there a > > way to turn it on globally? > > resolver(3) mentions RES_OPTIONS Yep - and neither resolver(3), nor the src/lib/libc/net/getaddrinfo.c source (specifically, the _dns_getaddrinfo() function) seem to describe/implement a resolver option that forbids AAAA queries.

But, I believe it shouldn't cause any problem. However, current getaddrinfo() doesn't see sortlist at all. It breaks backward compatibility against gethostbyname(). So, I'm writing a code to add sortlist facility to getaddrinfo(). Though the patch I sent to cvs-all touches only IPv4 address, I have the version which touches IPv6 address as well here. Once the patch is applied, you can write as following into /etc/resolv.conf: sortlist 0.0.0.0/0.0.0.0 ::/0 It means I want to see IPv4 address 1st. There is a discussion at IPng about destination address selection. This feature may be conflict with it in the future. So, I'm wandering if committing it into FreeBSD is better?
