How to show who has NFS mounted exported file systems

[Jay Gaffney_4]

showmount gives me a hostname that hasn't existed on my network in about 2 years.
Is there a better way to see who has mounted my exported file systems?

Hi,
may be that IP was re-used by another hosts, and no-one update the DNS or /etc/hosts...

Check also with exportfs to see to which hosts is exported.

Showmount is the only one I'm aware of. Like Massimo suggested, I'd review your DNS server and hosts files to see if you've got an old entry that needs updating.

.. about showmount and statmon. The lsof is the tool you need.
Hope this helps ..

Does this help:

exportfs -v


Good Luck

Have a look in your /etc/rmtab file.
You might find your 'ancient' hostname in there.
If you do find it you can just delete it and showmount will not report it any more.

HTH,

Hello,

The /etc/rmtab file is populated by the rpc.mountd when an NFS client sucessfully mounts the NFS Server. If the NFS client does a umount, then the /etc/rmtab entry is commented out.
If an NFS client crashes, reboots, or is removed from the network, the old stale /etc/rmtab entry will persist as it did in your case.
The /etc/rmtab file really does not serve much of a purpose other than for the showmount command. Some sysadmins trim the /etc/rmtab file if it gets unwieldy.

Hope that helps,

Also have a look at /var/adm/syslog/syslog.log. I guess You need to enable NFS logging for this.
