SHOWMOUNT(8)                           System Manager's Manual                          SHOWMOUNT(8)



NAME
       showmount - show mount information for an NFS server

SYNOPSIS
       showmount  [ -adehv ]  [ --all ]  [ --directories ]  [ --exports ]  [ --help ]  [ --version ]
       [ host ]

DESCRIPTION
       showmount queries the mount daemon on a remote host for information about the  state  of  the
       NFS  server  on  that  machine.   With  no options showmount lists the set of clients who are
       mounting from that host.  The output from showmount is designed to appear as though  it  were
       processed through ``sort -u''.

OPTIONS
       -a or --all
              List  both the client hostname or IP address and mounted directory in host:dir format.
              This info should not be considered reliable. See the notes on rmtab in rpc.mountd(8).

       -d or --directories
              List only the directories mounted by some client.

       -e or --exports
              Show the NFS server's export list.

       -h or --help
              Provide a short help summary.

       -v or --version
              Report the current version number of the program.

       --no-headers
              Suppress the descriptive headings from the output.

       rpc.mountd(8), rpc.nfsd(8)

BUGS
       The completeness and accuracy of the information that showmount displays varies according  to
       the NFS server's implementation.

       Because  showmount  sorts and uniqs the output, it is impossible to determine from the output
       whether a client is mounting the same directory more than once.

       showmount works by contacting the server's MNT service directly. NFSv4-only servers  have  no
       need  to  advertise their exported root filehandles via this method, and may not expose their
       MNT service to clients.
