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

NAME         top

       showmount - show mount information for an NFS server

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       -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.

BUGS         top

       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.
