showmount(1M) — ADMINISTRATOR COMMANDS
NAME
showmount − show all remote mounts
SYNOPSIS
/usr/sbin/showmount [−ade] [hostname]
DESCRIPTION
showmount lists all the clients that have remotely mounted a filesystem from host. This information is maintained by the mountd(1M) server on host, and is saved across crashes in the file /etc/rmtab. The default value for host is the value returned by hostname(1).
OPTIONS
−a Print all remote mounts in the format:
hostname : directory
where hostname is the name of the client, and directory is the root of the file system that has been mounted.
−d List directories that have been remotely mounted by clients.
−e Print the list of exported file systems.
FILES
/etc/rmtab
SEE ALSO
hostname(1), exportfs(1M), mountd(1M)
NOTES
If a client crashes, its entry will not be removed from the list until it reboots and executes umount −a.
