To look outside of mergemaster for a moment, on our systems (FreeBSD
and otherwise), we've traditionally used RCS to maintain system
configuration files. We keep the system-distributed files on branch
1.1.1 (known as the "vendor branch" in CVS speak), and these increase
1.1.1.1 ... 1.1.1.2 ... 1.1.1.3 with each OS release (we update these
manually). The trunk is used for our local changes, and we merge
the changes from the vendor branch onto it. Using RCS, it's easy
to see the local changes that have been made to the vendor release,
and to see the changes that have been made between OS releases.
For instance, to see the differences between a file and its distributed
version, we'd use something like this:
rcsdiff -r1.1.1 /etc/services
Since CVS is based on RCS (and it seems more appropriate here),
perhaps there could be a system CVS directory for /etc configuration
files. Using your idea of /usr/share/examples/etc containing the most
recent vendor files, there could be a tool which automatically merges
the files there onto the vendor branch in the system CVS directory.
That way, there would be no need for access to the main CVS repository
each time someone upgrades a server.
Just an idea.

I mount my /usr/ports, /usr/src, et al from an NFS server. Everything
seems to work fine except on one system where I've been seeing repeated
hangs. Of course the system in question is my main desktop one, sigh.
At first I was using gigabit Ethernet (Intel Pro/1000, 82545GM chipset)
but the interface kept wedging hard, also on this system (and _not_ on
the server, just on this one). I upgrading the system to 6.0-beta5 to
see if the interface hangs went away. (I upgraded by
NFS-mounting /usr/src over my parallel 100BaseTX network rather than the
Gigabit network.) The upgrade worked fine but the hangs didn't
disappear. I planned to swap out the gigabit card to see if it was the
hardware that was the problem, but in the interim (not having a spare
card lying around) I decided to do a complete portupgrade using the
100BaseTX network.
This is where it gets weird. Because of all the hangs I've run into, at
some point I made all the NFS mounts soft mounts. I've been watching
these port builds, and from time to time, with no obvious pattern that
can discern, NFS hangs. The server seems perfectly healthy and in fact
the _interface_ seems healthy, but the particular I/O in question just
hangs until it eventually times out due to the soft-mount.
After it finally times out, things pick up and keep going again. NFS
works fine for a while, then it hangs again.
I captured one of the hangs; this is from the client machine:
16:17:53.642822 IP realtime.exit.com.560259720 > jill.exit.com.nfs: 132
read fh 1070,983185/1114384 8192 bytes @ 1925120
16:17:53.643541 IP jill.exit.com.nfs > realtime.exit.com.560259720:
reply ok 1472 read
16:18:11.679433 IP realtime.exit.com.560259720 > jill.exit.com.nfs: 132
read fh 1070,983185/1114384 8192 bytes @ 1925120
16:18:11.680142 IP jill.exit.com.nfs > realtime.exit.com.560259720:
reply ok 1472 read
So the server gets the read and replies, but the client apparently never
sees the reply (despite the fact that it is coming in on the interface
and gets picked up by tcpdump).
I've attached the dmesg from the client, if it helps, but I doubt it
will. I can't imagine that this is hardware, although I guess it
_might_ be. It's just very weird. Any hints as to cause or further
steps I can take to diagnose it would be appreciated.

I want to make a freebsd port of JFS2. The source code is available at
http://jfs.sourceforge.net/

stop using ufs.

I will make it a seperate module (which is how it exists in linux).
It may not be appropriate to be used as a boot filesystem. If someone
from freebsd is interested in reviewing the port -pl. let me know.

It turns out that fill_kinfo_thread() grabs a bunch of locks to grab
things out of struct proc, which breaks badly if sched_lock is grabbed
before calling fill_kinfo_thread().
I refactored fill_kinfo_thread() into two functions, one of which
doesn't need any additional locks and only gathers per-thread data, and
a new function, fill_kinfo_proc_only(), which gathers the data that is
common to all theads and can be called before grabbing sched_lock. This
should be more efficient if there is more than one thread because the
per-process data is only gathered once, and only the per-thread data in
kinfo_proc is overwritten for each thread.

Hi,
I need to set serial port to given parity/speed/etc. and then cat from it...
when I: stty -f /dev/cuaa0 speed 1200
its still at 9600 (the default setting)
how do I alter speed of serial port? minicom/cu is able to do it but I want to
do it via stty.
how can this be done?
thnx for answer

See discussion of the initial-state and lock-state devices in the sio
manual page.
Another, hacky way to do it is like this:
sleep 1000 < /dev/cuaa0&
stty -f /dev/cuaa0 speed 1200
The sleep holds the device open so that the values set using stty remain
effective. Without the sleep the stty values are only effective while
the command is being executed because stty opens the device and then,
once stty exits, the device is closed and all the new settings are lost.

I don't think the dump problem is device/firmware related, as a
reboot -d gives me a dump just fine.

Hmmm, so we have a very elusive problem here, one that is not easily
pinpointed.. Somehow, this does not come as a surprise :)

Right, so perhaps i am missing something here, but this in my kernel
config should do it (full config included below for completeness
sake, as well as dmesg output):
# debug
options KDB
options DDB
#
options KDB_TRACE
#
makeoptions DEBUG=-g
# debug
Furthermore, since reboot -d does dump to swap now (by limiting
physical memory to just below the swap partition size in the
bootloader config), i would expect to get a dump also when a panic
occurs, and i would expect a ddb> prompt. Alas, this is what i get:
kernel trap 12 with interrupts disabled
Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 06
fault virtual address = 0x24
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc051c253
stack pointer = 0x10:0xe93efb3c
frame pointer = 0x10:0xe93efb50
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 6092 (postgres)
And that, that is all.. No ddb> no 'dumping xxxxMB', just that. So
basically, i fear this is a non-debugable problem, since putting in
witness and such slows the kernel to a point where the panic does
not occur anymore (at least, not in the 4 weeks i've been running
the box with witness & invariants). Clueless :)
Best,
Koen

Hi all,
I proposed to import bio aka RAID Management Framework from OpenBSD.
I have studied how bio is implemented in OpenBSD and here is a quick
resume of the 3 components that make bio:
- bio - ioctl tunnel pseudo-device
/dev/bio.c biovar.h
The bio driver provides userland applications ioctl access to devices
otherwise not found as /dev nodes. The /dev/bio device node operates =
by
delegating ioctl(2) calls to a requested device driver. Only drivers
which have registered with the bio device can be accessed via this int=
er-
face.
- ciss, amr - supported device drivers
- bioctl - RAID management interface
RAID device drivers which support management functionality can register
their services with the bio(4) driver. bioctl then can be used to mai=
n-
tain RAID volumes.
After analysing the structure of /src my initial idea was:
new /src/sys/contrib/dev/bio/bio.c biovar.h
new /src/sys/modules/bio/makefile
new /src/contrib/bio/bioctl.c
edit amr and ciss to register themselves on bio
1st: are these the correct places to be putting this files?
2nd: the drivers need to register to bio, this one being a kernel
module. If bio is not compiled in that can represent a problem. Ideas?

mpd-3.18 doesn't work on AMD64. Future mpd-3.19 will work. However,
the problem is already fixed in mpd port. You need to update your
ports tree and resintall mpd.

I'm looking for some tips on how to troubleshoot a possible driver
problem. Here is the scenario:
1. Using a Pentium II 333Mhz mobile processor, 82443BX motherboard, and
Intel i82559 NIC (fxp driver).
2. A combination of heavy disk I/O, high CPU utilization, and high
network traffic causes a solid machine freeze-up sometime between 10
minutes and 3 hours of running.
3. Replacing the NIC with a DP83815-based card (sis driver) seems to
solve the problem. I have run the problem load for up to 8 hours without
issue on this NIC.
4. The problem is reproducable on multiple identical machines with
multiple identical NICs. Also reproducable on an i82558 NIC integrated on
the motherboard.
How can I go about collecting useful information to troubleshoot this
when the machine locks solid? How can a get a core under this scenario?
Switching to another NIC permanently is not a great solution because this
is a semi-embedded application and I need to use the NIC on the
motherboard.
Thanks,
David Madole

You can't break to DDB in the usual way, right (Ctrl+alt+esc)? Try
turning on KDB_STOP_NMI instead. Also try turning on WITNESS in case
you're seeing a lock order reversal. Actually you forgot to mention
what version of FreeBSD you're running, those suggestions only apply
to 5.x and above.

After fixing a few whitespace nits and one minor buglet, I commited my
patch to HEAD, in kern_proc.c 1.232. I hope to be able to MFC it soon.

The normal method is to use a break signal to get into the debugger.
Depending on your hardware and software configuration, this may be more or
less easy. First, you'll need to configure options BREAK_TO_DEBUGGER into
your kernel. You can break into the debugger in one of three ways:
(1) Ctrl-alt-esc on a syscons console. Note that because the syscons
console is under the Giant lock, reliability of this mechanism to get
into the debugger on FreeBSD 5.x is reduced. It is quite a bit better
in 6.x, and will continue to get better as the use of Giant is
reduced. If this doesn't work for you, try (2).
(2) Serial break on the first serial console port. Because the sio driver
uses a fast interrupt handler, this is quite a reliable way to get
into the debugger unless interrupts are disabled, in which case the
serial port can't interrupt the CPU to drop into the debugger. If
this doesn't work for you, try (3).
(3) Break to debugger using an NMI. Some hardware, especially evaluation
hardware, comes with an NMI button, frob, or other way to initiate a
drop to the debugger despite interrupts being disabled. Hardware
watchdogs are often also able to generate an NMI.
I find that, except in pretty exceptional circumstances, (2) works quite
well. You can find a section on kernel debugging in the FreeBSD handbook;
my general advice is to compile in KDB, DDB, BREAK_TO_DEBUGGER, WITNESS,
and INVARIANTS, and see where that gets you using a serial console. DDB
is pretty easy to use for basic debugging -- i.e., checking thread state,
checking lock state, generating stack traces, etc. Depending on the bug,
you might also need/want to use kgdb via serial or on a core dump.

hello,
i was wondering what/where changes should i do to make files when
moving a file from directory to another in the kernel source.
for example if want to move all /usr/src/sys/i386 , /usr/src/sys/ia64
in /usr/src/sys/intel/i386 and /usr/src/sys/intel/ia64.
so can any one point me to any document or webpage that discuss this stuff =
?
thanks you very much
Maslan

Thanks for more answers :)
I has finished this. But i have one question, how to I should act with a
dummynet code?
Through a pseudo device /dev/ipfwctl we can control an ipfw state.
The access to ipfwctl device can be configured via devfs.conf.
User must have a write permissions to /dev/ipfwctl for change ipfw state
and a read permissions for read ipfw state.
Patch can be found here: http://butcher.heavennet.ru/ipfw_ioctl/

Thanks for reply.
Wow, postifx got their power. Very simple.
But I really want to know about Sendmail, because it's default in many Unix.
Checking out http://www.technoids.org/procmailfilter.html but it seems
quite complex.

I think you want sendmail's -X option:
-X logfile
Log all traffic in and out of mailers in the indicated log file. This
should only be used as a last resort for debugging mailer bugs. It
will log a lot of data very quickly.

John,
We tried this patch and were able to run our simulations (and top) for 3
days straight without crashing. Since we were panicking every 3-6 hours
before when running top, this seems to have fixed the problem.
We noticed the patches from Don Lewis, but have not tested them yet. We
weren't sure if we could just apply those patches against 6.0-BETA5, or
whether we should wait for them to be MFC'd.

You can use mailsnarf (part of dsniff port) tosniff all the mails

This looks like a NULL pointer dereference in kernel code. Probably, this
is not a locking problem, so running without WITNESS to debug this should
be OK. Are you using a serial console? If not, you might find that it
increases the reliability of entering DDB. If this box is an SMP box, you
may also want to add options KDB_STOP_NMI to your kernel config.
Using gdb, could you work out what function 0xc051c253 is, and where in
the function. You should be able to run gdb on your kernel.debug (or
kernel on 7.x), and use "l *0xc051c253" to generate a pointer to the line
and snippet, which will give us a substantial hint about what is
happening.

Hello,
I've got an AMD64 compatible machine which dies with
"Too many segments in the physical address map, giving up".
This error is defined in src/sys/amd64/amd64/machdep.c
Changing the following define:
#define PHYSMAP_SIZE (2 * 8)
to
#define PHYSMAP_SIZE (2 * 16)
has solved the problem, the machine boots and works without any
noticeable side effect.
Are there any reasons to keep this and not to increase PHYSMAP_SIZE?
Thanks,

I'm applying flock() to a file that is on an NFS server.
The program calling flock() is built on a 4.5 system,
with the 4.5 libraries, etc...
The NFS server is a 4.5-RELEASE system. The program running on a
4.5-release system doesn't display any problems.
But - when I run that same program on a 5.3-RELEASE system,
flock() returns with a -1 and sets errno to EHOSTUNREACH.
Of course, the code is checking for EEOPNOTSUPP, but it doesn't
expect to see EHOSTUNREACH from flock(). We changed it to set
errno to zero to make sure that simply wasn't a dangling value
in errno.
Any ideas about what could be going on? Should flock() be
setting errno to EHOSTUNREACH? And, as the file can be read,
I don't understand where the EHOSTUNREACH comes from (the host
is very reachable.)
- Thanks! -

Hi,
I am trying to boot a diskless box (via PXE), both server and diskless
run FreeBSD 6.0-BETA4. The diskless machine hangs after printing
the date on the console. I added debug output to /etc/rc,
/etc/initdiskless and finally /sbin/init. It seems to hang in init
after calling multi_user().
A bit before the hang, rc.initdiskless does
sysctl -n kern.bootp_cookie and it prints:
sysctl: unknown oid 'kern.bootp_cookie'
Is this a known issue? I can upgrade to -current if needed.
PS in the process of setting up the diskless root I also updated
clone_root to work with fbsd > 4.x, retaining 4.x compatibility,
seems to work fine.
thanks
marco

It works for me basicly the same way it has since 4.x. I don't use the
clone_root procedure and use installworld/kernel with DESTDIR set.

I'd like to announce a new utility for FreeBSD, named "ggtrace". It's a
graphical (X11) utility that displays I/O on a ggate device in a window.
It can attach to any device or file, producing a /dev/ggateN device which
can be used as usual - for example for hosting filesystems. All I/O
requests are logged and displayed as a histogram of activity.
The sources are here:
http://ivoras.sharanet.org/stuff/ggtrace.tgz
You'll need X11, libpng and wxgtk26-contrib ports installed before
building it. Read the README file before using the application!
This is still software under development and I'd like to hear any feedback
you might have on it :)

I have the following rules:
$fwcmd add 600 pipe 602 src-ip 192.168.0.0/24 out
$fwcmd add 601 pipe 603 dst-ip 192.168.0.0/24 in
$fwcmd pipe 602 config mask src-ip 0x000000ff bw 128Kbit/s queue 10KBytes
$fwcmd pipe 603 config mask dst-ip 0x000000ff bw 128Kbit/s queue 10KBytes
And my test speed from ip 192.168.0.5 is:
Down 123.66kbps
Up 766.24kbps
Which the problem?

hello,
Im trying to install FreeBSD 6.0 beta5 on a samsung SP1604N hard
disk of about 160 GB.
The installer complains that it has a problem with the disk geometry.
The exact message is given below:-
------------------------------------------
A geometry of 310101/16/63 is incorrect for ad1. Using a more likely
geometry. If this geometry is incorrect.. pl. consult the hardware guide
-------------------------------------------
fdisk goes through the process of creating the reqd slices and when I
try to commit the new partition table -it says it cannot write to /
dev/ad1.
Can someone tell me how to get past this problem?
thanks
-kamal

I doubt it is your disk geometry. You will probably need to provide a
little more information. I assume you've got another OS on /dev/ad0 and
that you are letting sysinstall put 6.0 onto /dev/ad1 as a (dangerously)
dedicated drive? What does the BIOS report? How old are the machine
and its BIOS? What does fdisk say when run either standalone or from
the first OS?

ad0 is running windows XP and that works fine. ad1 is a new drive (I
delted the windows partition that existed on it) on which i wish to
install freebsd. I inserted the CD for 6.0-i386-disc1.iso and it gave
the msg I mentioned before going to fdisk. fdisk allows me tocreate
slices and then I can select mount pt etc.. on the next screen. When
we try to write that information, the operation fails. I mean, there
is a problem with doing an I/O operation on that hard disk

The motherboard is an "American Megatrends Corp" board with a pentium
4 chip on it
they ahve a propreitary bios on it -but its all post 2003 stuff.
Its the same result for fdisk whether you run standalone or from the
installer.

All,
again three month went by and exiting stuff has happend in FreeBSD. Many
subtle bugs have been identified and fixed during the most productive QA-work
in preparation for FreeBSD 6.0 (now entering final RC-phase). The Google
Summer of Code has produced a lot of exiting projects; either finished (most
visibly the new website) or still worked on enthusiastically. Work in HEAD
is also taking off and promises to bring even more exiting stuff for the
future ...
I am sure you have interesting things to share for this round and we are
looking forward to your reports. Please send status reports about your
project's progess between July and now to monthly@freebsd.org
To help you with fileing your report you will find a webform[1] or
xml-template[2] linked from http://www.freebsd.org/news/status/
Submissions are due October 15. Thanks a lot, and we are hoping for a big
turn-out.

Do you have additional rules that you haven't shown, such as a divert
rule for NAT?
Perhaps because of NAT the source address is not what you think it is at
rule 600 and you need to move that rule before your divert rule.

Hi guys,
me and other testers have encountered a strange problem when booting
=66rom CDroms created with freesbie2 toolkit: the date is set to
epoch. This don't happens with ufs image, only with iso with cd9660
root set.
The iso is created with:
mkisofs -b boot/cdboot -no-emul-boot -J -r -ldots -l -L -V ${LABEL} -p Free=
SBIE -o $ISOPATH .
which is almost the same way used in release scripts.
How can I help debugging this?
Thanks to everybody,
Dario

Hi,
is there any special reason for timeval.tv_sec being long?
--- sys/_timeval.h
/*
* Structure returned by gettimeofday(2) system call, and used in other
calls.
*/
struct timeval {
long tv_sec; /* seconds (XXX should be
time_t) */
suseconds_t tv_usec; /* and microseconds */
};
---
I just stumbled across this code in an application,
---
timeval tv;
gettimeofday(&tv, 0);
char tbuf[64];
struct tm tmp;
strftime(tbuf, sizeof(tbuf), "%b %d %H:%M:%S", localtime_r(&tv.tv_sec,
&tmp));
---
and this fails to compile on FreeBSD. I fixed the application code now,
but I do wonder why that XXX in sys/_timeval.h is there.
_timeval.h came into existence on 31-Dec-2002, before that timeval was
defined in sys/time.h with both tv_sec and tv_usec as long.
Could anyone offer any pointers?
Best regards,
--
Andreas

qmail:

Other than that, see also maildrop (same people) or fetchmail. Google
that or try the ports tree.

If you trawl the archives for comp.mail.sendmail you will find many solutions.
One of these is MIMEDefang, but there are a large number of others.

Certainly in the class of 'Doctor: If I poke in my eye it hurts; well
don't do that then') - on FreeBSD -current as of today.
Add /mnt to your exports file on an NFS server; and do:
mdconfig -a -t vnode some-disk
mount /dev/md0a /mnt
killall -1 mountd
..
let at least one nfs client mount it.
Then do
umount - /mnt
mdconfig -d -u 0
First XS by the nfs will panic the machine - the actual stacktrace it self
is too corrupted to see where.

tv_sec is presumably long becuase that way 64-bit platforms end up with
timevals that don't suffer from the 2038 bug. time_t is also long (or
rather synonimous with it) on all but alpha platforms.

You probably can just cast the tv.tv_sec to a time_t. Alternativly, you
could allocate a time_t and assing tv_sec to it since that will work on
alpha where the other won't.

Thanks for this explanation.
As SUSv2 wants tv_sec to be time_t[1], would it be possible to change
this to time_t on all but alpha? I guess alpha will not receive a switch
to long anymore[2].=20
This would still require workarounds as you suggested below for alpha
(nothing changes here), but would at least bring !alpha closer to
standards compliance, which would be a good thing IMVHO.

Yep, I did the latter, and it works. Thanks.

tv_sec and time_t are int on Alpha for compatability with Tru64. Since
the Alpha is now a dead architecture and no longer a tier-1 FreeBSD
platform, it's unlikely anyone will expend the effort to change them.

Both HEAD and RELENG_6 have been patched. I've tested the following
patch for RELENG_5 on a uniprocessor sparc64 box. I'd appreciate it if
anyone who was running into this problem on RELENG_5 with SMP hardare
could test it before I do the MFC.

All,
I'd like to set SENDMAIL_MC in my /etc/make.conf files conditionally
so that it is not set when I'm making {build,install}world. I
upgrade several machines over NFS from a single build server, and
of course installworld breaks if SENDMAIL_MC differs from what was
set during buildworld. At the same time, I'd like to have SENDMAIL_MC
set for the rest of the time on the machines because `hostname` is
not a suitable way to construct the .mc names on them due to local
setup peculiarities. Any ideas how to achieve this effect?

It is possible to override make.conf location via __MAKE_CONF variable
and use different make.conf at the build,installworld stages.
Perhaps that suits your needs.

I found out that my samsung 1604N hard disk can be partitioned
without any problem (it is now the primary master with a dvd drive as
slave).
.
The problem lies with disklabel. If I use 'A' option in the
sysinstall program's label section,.
it expects to find in /dev ad0s1a, ad0s2a etc.. but these don't show
up in /dev and the labelling procedure fails. Can someone tell me how
to fix this or if this is a bug in this release of freebsd?
thanks

If that is the only reason, make it use time_t and add a fake field on
Alpha before or after it (not sure of the byte order) to keep the alignment.

That's what I was implying, yes. So, is there any reason left (except
perhaps envious looks from the alpha guys :D) not to change it?=20
Shall I open up a PR on this?
The only thing I'm currently wondering if it would be better to do=20
--- sys/_timeval.h
#ifdef __alpha__
long tv_sec;
#else
time_t tv_sec;
#endif
---,
or creating a machine/_timeval.h.
#ifdef __alpha__ would probably okay, there are more files in sys/ that
do that.
I think this is an important issue, as it currently makes code not
compile on FreeBSD that uses standard interfaces.=20
Attached is a patch to at least update gettimeofday(2) with the fact
that tv_usec is suseconds_t, and add a BUGS section to note the problem
with tv_sec. I was unsure whether to add the reasoning behind the
problem (alpha, tru64), so I left that out.
Best regards,
Andreas

I shouldn't write this while I'm frustrated. I just hope it doesn't
leak out, I know I tend to do that.
I'm having trouble getting my mounts to work with my newly attached
Zaurus, to my trusty FreeBSD server. I have gotten past several
problems, began googling error messages, and hit the /etc/hosts.allow
file. Here I've hit a problem. The file, both the internals of it
(which is a mass of examples with nearly no explanations) and the man
page, are either circular definitions, or missing ones, grossly
missing. One glaring example, in the man page, the single most commonly
used token is "ALL" but even though it's used more than any other token,
it's not defined, even slightly. What does ALL mean?
Hmm, howcome security info, which is the most important, is always the
worst documented, and set up with the most complicated syntax?
If you MUST use examples, they should only be used to illustrate items
that have explanations, they should never ever be used as the primary
explanation. I can't figure out how to use /etc/hosts.allow. I'm not
sure if it is, or is not, affecting my rpcbind.
Well, you be the judge, did I let my frustration out of the bag this time?

This kind of question is asked frequently. If your machine isn't
panicking (check the system console, and make sure you're not running
X there), it usually means you have failing or marginal hardware that
is unable to keep up with peak loads. Try replacing your power
supply, or putting it behind a UPS that can condition the power if
your AC supply is dirty or unstable.

Quoting the "hosts_access" man page:
ALL The universal wildcard, always matches.

The man page for rpcbind suggests it should, and you can find out (again, from
the man page):
-l Turn on libwrap connection logging.

My guess, and this is a wild one, would be:
All \All\, a. [OE. al, pl. alle, AS. eal, pl. ealle,
Northumbrian alle, akin to D. & OHG. al, Ger. all, Icel.
allr. Dan. al, Sw. all, Goth. alls; and perh. to Ir. and
Gael. uile, W. oll.]
1. The whole quantity, extent, duration, amount, quality, or
degree of; the whole; the whole number of; any whatever;
every; as, all the wheat; all the land; all the year; all
the strength; all happiness; all abundance; loss of all
power; beyond all doubt; you will see us all (or all of
us).

I could sure use some help here.
I have this Zaurus pda, running OpenBSD (FreeBSD doesn't run on arm,
last I looked), and I have just gotten usb networking to work. I am
trying to get nfs mounts to work, and I have very nearly got it working,
except for one problem: permissions.
For example, I have a /usr3/local that I want to mount as /usr/ports on
the Zaurus. When I do that (and it does mount), if I try to "touch
garbage", it comes back and tells me "Permission denied". I can't get
around this. The mount isn't ro, in fact, when I do the mount -v, I get:
april.chuckr.org:/usr3/osrc/ports on /usr/ports type nfs (rw, ctime=Sat
Oct 8 10:23:49 2005, v3, tcp, hard, wsize=8192, rsize=8192,
rdirsize=8192, timeo=100, retrans=10, maxgrouplist=16, readahead=1,
acregmin=5, acregmax=60, acdirmin=5, acdirmax=60)
Showmount -e on FreeBSD shows the right network (I was going to post it,
but I chickened out, it's got too much stuff I don't want publicized, I
have static IPs).
How come I can't get permissions fixed?

you didn't say whether you tried as a normal user or root, for normal
users you should use the same uid and gid on both machines, for root
you need to appropriate syntax on the nfs-server (you could show that
part of /etc/exports changing your ip-addresses)

Keep in mind that the root user isn't mapped across an NFS mount by default:
In the absence of -maproot and -mapall options, remote accesses by root
will result in using a credential of -2:-2. All other users will be
mapped to their remote credential.
If you want a remote system to have root access to the file system you *MUST*
explicity configure this.

Someone else pointed out hosts_access(5). I just wanted to point out
that unless you did something to it, it's probably not. The file is
run through first-match, and the first non-comment line in the default
file is:

Are you doing this as root or as an ordinary user? If the former, do
you have '-maproot=root' for /usr3/local in april:/etc/exports? If
the latter does the user have permission to write to /usr/ports?

I think that mount on the client will report rw even if the server
only exports ro.
