mount.nfs: access denied by server while mounting (null), can't find any log information
- by Mark0978
Two ubuntu servers: 10.0.8.2 is the client, 192.168.20.58 is the server.
Between the 2 machines, Ping works, ssh works (in both directions).
From 10.0.8.2
showmount -e 192.168.20.58
Export list for 192.168.20.58:
/imr/nfsshares/foobar 10.0.8.2
mount.nfs 192.168.20.58:/imr/nfsshares/foobar /var/data/foobar -v
mount.nfs: access denied by server while mounting (null)
Found several things online, tried them all and still can't find any log information anywhere.
On the server:
[email protected]:/var/log# cat /etc/hosts.allow
sendmail: all
ALL: 10.0.8.2
/etc/hosts.deny is all comments
How can I get a trail of log statements to figure this out? What does it take to get some logging so I have some idea of WHY it won't mount?
On the server:
