Hi Kevin,
I am able to forward and reverse lookup the server and client via DNS from both machines. The only change required from my setup to make this work is to replace the gss/krb with * in the /etc/exports file (and a service nfs restart on the nfsserver).

Any other thoughts?

Thanks!
Jonathan

On the server, in /var/log/messages:
mountd[2517]: mount request from unknown host myclientipaddress for /home/NFS4 (/home/NFS4)
I think it may be a dns issue, but I'm not sure why you wouldn't see the error w/o Kerberos. What does your /etc/exports look like on the server? Can you do a reverse dns lookup of the client's IP from the server machine?

Sorry, I know you had the /etc/exports in the original message. I meant to remove that before sending the message :-/

I've not ever seen this error personally. I'm still stumped on why you only see it with Kerberos.

What kernel and nfs-utils versions are involved here?
