(i got a suggestion that 'this' is an NFS issue, not just FreeBSD ...
i honestly don't know atm ...)

i'm running freebsd 6.2rp9.

i serve/mount via nfs between boxes on a regular basis w/o issues.

now, i'm trying to mount an NFS volume from within a jail.

@ the jail, when i

mount -v 10.0.0.2:/var/test /mnt

i get repetitions of:

[udp] 10.0.0.2:/var/test: NFSPROC_NULL: RPC: Timed out

i _thought_ i had the server/client correctly configured; apparently
not.

any hints as to what's wrong/missing?

details are:

@ server:

cat /etc/rc.conf

place of

nfs_server_flags="-u -t -n 4"
