showmount - Shows remote NFS compatible mounts on a host
/usr/bin/showmount [-adeT] [-t nnn] [host]
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. Lists
only directories that have been remotely mounted by

Specifies a timeout value, in seconds. The default timeout
value is 25 seconds.
The default value for host is the current hostname.
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.
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 systems mounted from the server
host. See NFS: Network File System Protocol Specification,
RFC1094, Appendix A for a detailed description of
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.
Specifies the command path Contains a table of local file
