showmount - Shows remote NFS compatible mounts on a host
/usr/bin/showmount [-adeT] [-t nnn] [host]
-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
Specifies a timeout value, in seconds. The default timeout value is 25
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 sys-
tems mounted from the server host. See NFS: Network File System Protocol
Specification, RFC1094, Appendix A for a detailed description of the proto-
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
Specifies the command path
Contains a table of local file systems mounted by remote NFS clients
