NFS problem: RPC: Authentication error

[dictum9]

Trying to get an Ignite image of a client (11.31) from an Ignite server (Ignite 7.8, 11.23) and getting the following:



May 6 09:41:29 portltst vmunix: NFS lookup failed for server a2opv: RPC: Authentication error

On the server, I get this:

rcmd_af: connect: portltst: Connection timed out


what does it mean?

The remsh command works just fine.

Hi,
Perhaps, you have a route issue, check client and server nfs
#netstat -rn
and check also the ping between them.

Hi,
I just search on itrc, there is a thread about this

Shalom,

The /etc/exports file on the server may have authentication protcols preventing a connection. Its pretty easy to filter based on hostname or ip address.

showmount -e a2opv

The server side stuff has nothing to do with this, at least not from an NFS perspective.

Setting Ignite aside, are you able to manually NFS mount filesystems between these two systems? If not, do you get the same error message?

Dear etc

make sure and entry of all host ip and name in /etc/hosts files

check in /etc/exports files if any hostname is there add it

export the files by using exportfs -a

thanks and regards

Turned out to be a firewall issue.
