on my home box (5.3-RELEASE) and there is _no_ _way_ I have ever been
able to make this work.
/etc/exports on the NFS server is configured correctly (other
exports to other boxen work fine)
my entry reads:
/usr/home/colin -mapall root 12.34.56.789 #home IP
Output of `showmount -e` is more usefull, then we can see what is
actually exported. NFS is very sensitive to errors in exports. You
probably don't want to use "-mapall root", but rather "-maproot=root",
see exports(5). Get rid of the comment, just to be sure.
Sorry, this got lost as I was replacing my server, just managed to get
the last dregs of data off the old one.

Second: What have you set in your rc.conf? Are all things up and
running?
>From /etc/rc.conf
nfs_client_enable="YES"
nfs_client_flags="-n 4" # Flags to nfsiod (if enabled)
from ps -aux |grep nfsiod
root 60 0.0 0.0 0 12 ?? IL Wed11AM 0:00.00 [nfsiod

root 61 0.0 0.0 0 12 ?? IL Wed11AM 0:00.00 [nfsiod

when - from the console as root - I do:
mount -v office.nfs.server:/usr/home/colin /office-box
You forgot to specify '-t nfs' or use 'mount_nfs' ?
OK, I now tried mount_nfs -LT office.nfs.server:/usr/home/colin
/home/colin/office-box (line wrapped in mail client only)
I get rewarded with this message:
First try:
[udp] office.nfs.server:/usr/home/colin: RPCPROG_MNT: RPC:
Authentication error; why = Client credential too weak
This time:
I get:
RPCPROG_NFS: RPC: Program not registered
quote:
Today I encounted this error for the first time. I was compiling a
kernel on my fast box and while I was waiting I set up the slow box. I
did this:
$ mount polo:/usr/src /usr/src
polo:/usr/src: RPCPROG_MNT: RPC: Authentication error; why = Client
credential too weak
That confused me. I checked /var/log/messageson the NFS server:
mountd[95]: mount request from 10.0.0.20 from unprivileged port
Ahhh! I wasn't root when I tried to mount! I su'd to root, and all was
well.
quote-end.
Well I was root when I did it, and that didn't seem to matter.
I think it would help following an updated guide :-), I have had no
problem exporting my /home. And, then post relevant settings from
rc.conf, exports, `showmount -e` etc.
OK, I'm in the FreeBSD handbook now
PS: I note you are nfs-exporting across the internet, are you sure that
is a good idea? Consider tunneling.
I tried googling on that, I wasn't successful in finding anything
relevant to FreeBSD, most of the stuff seems to be highly Linux
specific. It's a good idea, and one I'd like to do, but first I'd just
like to be able to prove it works...then work upwards to tunneling
Just a thought here, I'm behind an ADSL router, should I be port
forwarding some-port-or-other?
This should be *so* simple, clearly I'm overlooking something - and
knowing me - something obvious.
Sorry for the delay in responding, but at least now I found my missing
mail off the dead server.
