showmount(8) -- Linux man page



showmount - show mount information for an NFS server  


/usr/sbin/showmount [ -adehv ] [ --all ] [ --directories ] [ --exports ] [ --help ] [ --version ] [ host ]  


showmount queries the mount daemon on a remote host for information about the state of the NFS server on that machine. With no options showmount lists the set of clients who are mounting from that host. The output from showmount is designed to appear as though it were processesed through ``sort -u''.  


-a or --all
List both the client hostname and mounted directory in host:dir format.
-d or --directories
List only the directories mounted by some client.
-e or --exports
Show the NFS server's export list.
-h or --help
Provide a short help summary.
-v or --version
Report the current version number of the program.
Suppress the descriptive headings from the output.


rpc.mountd(8), rpc.nfsd(8)  


The completeness and accurary of the information that showmount displays varies according to the NFS server's implementation. Because showmount sorts and uniqs the output, it is impossible to determine from the output whether a client is mounting the same directory more than once.
