How to Check Connectivity on an NFS Client

1. Check that the NFS server is reachable from the client. On the client, type the following command.

   % /usr/sbin/ping bee bee is alive

   If the command reports that the server is alive, remotely check the NFS server (see "How to Remotely Check the NFS Server").

2. If the server is not reachable from the client, 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

3. If the name service is running, make sure that the client has received the correct host information by typing the following:

   % /usr/bin/getent hosts bee 129.144.83.117 bee.eng.acme.com

4. If the host information is correct, but the server is not reachable from the client, run the ping command from another client.

   If the command run from a second client fails, see "How to Verify the NFS Service on the Server".

5. If the server is reachable from the second client, use ping to check connectivity of the first client to other systems on the local net.

   If this fails, check the networking software configuration on the client (/etc/netmasks, /etc/nsswitch.conf, and so forth).

6. If the software is correct, check the networking hardware.

   Try moving the client onto a second net drop.
