NAME

  showmount - Shows remote NFS compatible mounts on a host

SYNOPSIS

  /usr/bin/showmount [-adeT] [-t nnn] [host]

OPTIONS

  -a  Lists all	mount points in	the form: hostname:dirpath.  In	this form,
      hostname is the name of a	client that has	remotely mounted a directory
      from an NFS server, and dirpath is the directory that has	been mounted.

  -d  Lists only directories that have been remotely mounted by	clients.

  -e  Shows exports list for host.

  -T  Specifies	an infinite timeout.  The default timeout value	is 25
      seconds.

  -t  nnn
      Specifies	a timeout value, in seconds.  The default timeout value	is 25
      seconds.

  The default value for	host is	the current hostname.

OPERANDS

  host
      Specifies	the name of the	NFS server for which you are displaying	mount
      information. If this operand is not specified, the showmount command
      uses the current hostname.

DESCRIPTION

  The showmount	command	shows status information about the NFS server on
  host.	By default, it prints the names	of all hosts that have NFS file	sys-
  tems mounted from the	server host.  See NFS: Network File System Protocol
  Specification, RFC1094, Appendix A for a detailed description	of the proto-
  col.

NOTES

  The mountd daemon running on the server only has an idea of the actual
  mounts, since	the NFS	server is stateless.  showmount	will only display the
  information as accurately as the mount daemon	reports	it.

  The default timeout value of 25 seconds can be too brief to read and verify
  an export list.  If you receive timeout messages when	using the showmount
  -e command, use either the -T	or the -t options to increase the timeout
  value.


FILES

  /usr/bin/showmount
      Specifies	the command path

  /etc/mountdtab
      Contains a table of local	file systems mounted by	remote NFS clients
