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 processed through \`\`sort -u''. ## OPTIONS - **-a** or **--all** List both the client hostname or IP address and mounted directory in host:dir format. This info should not be considered reliable. See the notes on rmtab in [**rpc.mountd**(8)](/rpc.mountd/8.md). - **-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. - **--no-headers** Suppress the descriptive headings from the output. ## SEE ALSO [**rpc.mountd**(8)](/rpc.mountd/8.md), [**rpc.nfsd**(8)](/rpc.nfsd/8.md) ## BUGS The completeness and accuracy 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. **showmount** works by contacting the server's MNT service directly. NFSv4-only servers have no need to advertise their exported root filehandles via this method, and may not expose their MNT service to clients. ## AUTHOR Rick Sladkey \
