No SUMMARY: NFS mount problem

First I would like to thank all the people who took the time to respond to
my emails. Your time is much appreciated.

Unfortunately, however, I did not manage to solve the problem. I can rlogin
from the old equipment - SG or Linux - onto the new serva but could not
mount NFS file systems. I can only guess it is something to the version of
NFS, but another Solaris 9 box we have works fine, so it remains a mystery.
We are now looking at phasing out the old kit instead.

Thanks again for all your help.

David

Continued thanks for all your help. I thought I was onto the solution with
the output from the snoop command, but it turned out the server was replying
with another name - it is a long story why - but this is not the cause of
the problem.

I re-ran the snoop (results below) with the server called bacall mounting
ing a directory called junk, and the snoop below shows the response from the
server. The directory did not mount.

Thanks again for any more suggestions.

man snoop, but something like snoop hme0 should work.

Then try the nfs mount and see what the output is.

UDP is connectionless,
TCP is connection orientated

Your version of nfs might be different than the other
machine. They might be using nfs version 2, udp, while
your using nfs version 3, tcp. Since the protocol isn't the
same, you won't be able to mount.

IPv6 information as well as udp/tcp info is on the site
mentioned below.
