I suspect that the fix for bug #141773 (which is presumably a security
issue because bugzilla won't let me see it) mentioned in the changelog
for the updated package has introduced this problem:
* Fri Feb 25 2005 <SteveD at RedHat.com> 2.12a-20
- Changed nfsmount to only use reserve ports when necessary
(bz# 141773)
I've just observed the exact same problem with my RH9 NFS server and
also with an HP-UX 11 server, though my RHEL3 and FC3 servers are
unaffected.
I suspect it might be possible to work around this by convincing
nfsmount that using the reserved ports is "necessary" for the older
servers, but I haven't figured out how to do this yet.
Paul.
