Help! I can't mount a NFS partition on the Linux server on my
FreeBSD box. After reading the various FAQs and mailing lists
on the FreeBSD site, I tried:

	mount annexia:/var/tmp /var/tmp
	mount -o -r=1024 annexia:/var/tmp /var/tmp
and	mount -o -P annexia:/var/tmp /var/tmp

All produced the same results - ``mount'' hangs. I can kill
it with ^C, but then any attempt to access /var/tmp causes
the machine to hang, and any attempt to retry the mount causes
a hang also.

Both machines are on the same segment, so I tried dumping
the net traffic with tcpdump. These are the results:

[ ... no activity for about 10 secs after issuing mount cmd ...]

The last three lines are repeated approximately every 2 to 3
seconds. The "port 1029 unreachable" messages look very
suspicious.

I can telnet, ping, X11 etc. between the two machines with no
problem.

Any help appreciated.

Rich.
