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.

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.
