NFS mouting with RPC: Authentication error

[sammysammy]

Server: DCSORA01, dcpbl03

System: Tru64 and HP Blade Linux



Problem description:

We have setup NFSD at DCSORA01 Tru64 server. The server is exporting a file system to one of the HP Blade Linuxs.

While we are getting the file system exported successfully to another Linux server, we are having difficulties to allow the HP Blade Linux server mounting the exported file system.

The error we are getting at the HP Blade Linux server is:



[root@dcpbl03 ~]# /bin/mount -t nfs dcsora01.com.au:/u01/oratst/tstappl/common /u01/oratst/tstappl/common

mount: RPC: Authentication error; why = Server rejected credential



Here is some more information about the NFSD setup:

Add NFS client's name and IP entry in NFS servers's /etc/hosts file.
