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 clients. Shows host's exports list. Specifies an infinite timeout. The default timeout value is 25 seconds. Specifies a timeout value, in seconds. The default timeout value is 25 seconds.
The default value for host is 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 protocol.
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.
