Hi,

I've read the NFS-HOWTO and have drawn a blank, please can you anyone help?

I need to share some cert files on another box, however I'm getting a
Segmentation Fault
whenever I attempt to mount the NFS share. This was all working fine for
months until a
change was made to a CNAME on our DNS Server. The CNAME was changed from
pointing to
192.168.99.11 to point at another server 192.168.99.23. Since then it has
not worked, I
can't see how this change could of messed things up on the NFS has I've
always used the
IP addresses.

The other thing that is strange is that it works fine if I mount from
192.168.99.99
to 192.168.99.10, but does not work when mounting to 192.168.99.11. Both
machines
192.168.99.10 and 192.168.99.11 are the same build and configuration.

All machines are connected locally using a Gigabit Switch on the same
network 192.168.99.0.

Can anyone please offer any advice?

Many Thanks

Paul
