How to Verify the NFS Service on the Server

1. Log on to the server as root.

2. Check that the server can reach the clients.

   # ping lilac lilac is alive

3. If the client is not reachable from the server, make sure that the local name service is running. For NIS+ clients type the following:

   % /usr/lib/nis/nisping -u Last updates for directory eng.acme.com. : Master server is eng-master.acme.com. Last update occurred at Mon Jun 5 11:16:10 1995 Replica server is eng1-replica-58.acme.com. Last Update seen was Mon Jun 5 11:16:10 1995

4. If the name service is running, check the networking software configuration on the server (/etc/netmasks, /etc/nsswitch.conf, and so forth).

5. Type the following command to check whether the nfsd daemon is running.

   # rpcinfo -u localhost nfs program 100003 version 2 ready and waiting program 100003 version 3 ready and waiting # ps -ef | grep nfsd root 232 1 0 Apr 07 ? 0:01 /usr/lib/nfs/nfsd -a 16 root 3127 2462 1 09:32:57 pts/3 0:00 grep nfsd

   Also use the -t option with rpcinfo to check the TCP connection. If these commands fail, restart the NFS service (see "How to Restart NFS Services").

6. Type the following command to check whether the mountd daemon is running.

   # /usr/bin/rpcinfo -u localhost mountd program 100005 version 1 ready and waiting program 100005 version 2 ready and waiting program 100005 version 3 ready and waiting # ps -ef | grep mountd root 145 1 0 Apr 07 ? 21:57 /usr/lib/autofs/automountd root 234 1 0 Apr 07 ? 0:04 /usr/lib/nfs/mountd root 3084 2462 1 09:30:20 pts/3 0:00 grep mountd

   Also use the -t option with rpcinfo to check the TCP connection. If these commands fail, restart the NFS service (see "How to Restart NFS Services").

7. Type the following command to check whether the rpcbind daemon is running.

   # /usr/bin/rpcinfo -u localhost rpcbind program 100000 version 1 ready and waiting program 100000 version 2 ready and waiting program 100000 version 3 ready and waiting

   If rpcbind seems to be hung, either reboot the server or follow the steps in "How to Warm-Start rpcbind".
