NFS mounting issues

[pedeb04]

When I try to configure backupmon to backup to a Network-NFS I get an error.
My test confige is:
(1) : Test Target Media Type : Network-NFS

(2) : Test Target Username : admin

(3) : Test Target Password : admin

(4) : Test Target NFS Path : 192.168.50.46:/srv/nfsshared

|--- Test NFS Mount Options : nfsvers=3,nolock,_netdev,rsize=8192,wsize=8192

(5) : Test Target Backup Mount Point : /tmp/mnt/testbackups

(6) : Test Target Dir Path : /router/test-backup

(7) : Test CIFS/SMB Version : N/A

My message is bad file descriptor.
I also tried without the NFS Mount options, bad file descriptor
I can mount from the server nfs share from my linux desktop ok.
my server /etc/exports
/srv/nfsshared 192.168.50.0/24(rw,root_squash)

I am thinking that the root_squash directive on your server might be an issue. The router is trying to connect as user root which your server will change to an anonymous user. If your permissions on the server do not allow for an anonymous user it may be the reason it's failing.

It's just a thought as I'm no expert with NFS.

Following up on this while doing some googling, you could try modifying your exports file on your server;

/srv/nfsshared 192.168.50.0/24(rw,root_squash,anonuid=xxxx,anongid=xxxx)

Where xxxx is the actual uid and gid you want mapped when a root user mounts the share.

The anonuid and anongid directives work alongside the root_squash directive by changing the uid and gid of the anonymous user from the system default uid/gid to the specified uid/gid.
