39078:save:PRC error
Hi Everyone,
I am running Neworker 7.5.1. alot of the servers are not backing up and getting an error:
39078:save:RPCerror:Aunthentication failed or no valid authentication methods supported by both client and server.
Thanks for any ideas.

Hi,
The most likely cause of this is name resolution problems between the client and server machines. Ensure that the FQDN,shortname and IP Address are present in the hosts file on both sides and that Reverse DNS lookup works for all names and the IP. You can compare the results for those that are working and those that are not which should help to sort this out. The best way to test the connection between the two machines is to use the nsradmin command:
From the server: nsradmin –s -p 390113
From the client: nsradmin –s
From the client: nsradmin –s -p 390113
If this gets through to the nsradmin prompt, then the connection is ok, otherwise it is not. Check also that /nsr/servers file on the clients is correctly configured with the server's name. If you have a firewall between the two machines, you might want to look to see if you have enough ports open also.

Hello,
Run the following command to verify the communication between them and the ports from both servers.
from the backup server
rpcinfo-p CLIENT_NAME
client from the server
rpcinfo-p backup_server
Also to check the DNS
nslookup CLIENT_NAME
nslookup backup_server

If auth model is the problem, you may wish to disable nsrauth on server and storage nodes (requires restart of NW after that).
