Two questions:
- Are the machines (HP-SUX server and Linux client) on the "same"
network (as in physical domain), or is some kind of possibly filtered
routing going on?
- I'm not sure whether you need the portmapper running on a
client-only nfs machine... You could give it a shot by issuing
service portmap start
before trying the mount (or use 'service portmap status' first on both
the working and non-working client to find out if it's running). I'm
not sure whether 'service' is available on 7.1, if not use
/etc/rc.d/init.d/portmap start
/etc/rc.d/init.d/portmap status
More thoughts/debugging ideas:
- Does reverse dns work for one of the linux hosts, but not the other
(as seen by the HP-UX)? Or is one of the linux hosts in the HP-UXs
/etc/hosts, but not the other?
(I.e. can the HP-UX determine the name of the working client but not the
name of the not-working client given its IP adderss - classical
headache.)
- Does the following command show you which exports are available
from the HP-UX host (try this on both machines as well):
showmount -e 192.168.69.224
(I've used the server IP you gave in the example above).
- Last resort, trace the network traffic at the linux machine:
tcpdump -i eth0 -s 1600 -v -v host 192.168.69.224 |& tee /tmp/nfsdebug
Leave this running while trying to mount (for best results, once on
the working and once on the not-working host again); then stop the
tcpdump with Ctrl-C. I'd be willing to look over the traces (saved in
/tmp/nfsdebug by the command above).
So long,
Joe
