Hi folks,
I've been trying to accomplish the simple task of mounting filesystems
from a central server 'hostA' onto a new client 'hostB'. the new client
has a basic 3.3 'bin' distrib installed on it and I am trying to mount
/usr/src & /usr/obj from hostA so that I can upgrade it.
the problem is that the mounts hang and never succeed. i've added hostB to
hostA's /etc/exports file of course. other machines are already mounting
from /usr/src etc. from hostA with no problems.
i've tried a different NIC, different machine and a 3.3-STABLE kernel with
no luck.
tcpdump on hostA :

..
notice the icmp port unreachable msgs, yet on hostB:
netstat -a :
..
udp 0 0 hostB.1018 hostA.nfsd
..
ps axlw :
..
0 254 1 0 2 0 340 200 sbwait D v0 0:00.01 nfs -o ro -o noatime -o noauto hostA /usr/src (mount_nfs)
..
any ideas ?
Thanks,
Cillian
