How to Check the NFS Server Remotely

  1. Check that the NFS services have started on the NFS server by typing the following command:


    % rpcinfo -s bee|egrep 'nfs|mountd'
 100003  3,2    tcp,udp,tcp6,upd6                nfs     superuser
 100005  3,2,1  ticots,ticotsord,tcp,tcp6,ticlts,udp,upd6  mountd  superuser

    If the daemons have not been started, see How to Restart NFS Services.

  2. Check that the server's nfsd processes are responding.

    On the client, type the following command to test the UDP NFS connections from the server. 


    % /usr/bin/rpcinfo -u bee nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting

    If the server is running, it prints a list of program and version numbers. Using the -t option tests the TCP connection. If this command fails, proceed to How to Verify the NFS Service on the Server.

  3. Check that the server's mountd is responding, by typing the following command. 


    % /usr/bin/rpcinfo -u bee mountd
program 100005 version 1 ready and waiting
program 100005 version 2 ready and waiting
program 100005 version 3 ready and waiting

    If the server is running, it prints a list of program and version numbers that are associated with the UDP protocol. Using the -t option tests the TCP connection. If either attempt fails, proceed to How to Verify the NFS Service on the Server.

  4. Check the local autofs service if it is being used:


    % cd /net/wasp

    Choose a /net or /home mount point that you know should work properly. If this command fails, then as root on the client, type the following to restart the autofs service:


    # /etc/init.d/autofs stop
# /etc/init.d/autofs start

  5. Verify that file system is shared as expected on the server.


    % /usr/sbin/showmount -e bee
/usr/src										eng
/export/share/man						(everyone)

    Check the entry on the server and the local mount entry for errors. Also check the name space. In this instance, if the first client is not in the eng netgroup, that client would not be able to mount the /usr/src file system.

    Check all entries that include mounting information in all of the local files. The list includes /etc/vfstab and all the /etc/auto_* files.
