NAME

6       showmount - show mount information for an NFS server
7

SYNOPSIS

9       showmount    [ -adehv ]   [ --all ]   [ --directories ]   [ --exports ]
10       [ --help ] [ --version ] [ host ]
11

DESCRIPTION

13       showmount queries the mount daemon on a  remote  host  for  information
14       about  the  state  of  the NFS server on that machine.  With no options
15       showmount lists the set of clients who are  mounting  from  that  host.
16       The  output from showmount is designed to appear as though it were pro‐
17       cessed through ``sort -u''.
18

OPTIONS

20       -a or --all
21              List both the client hostname or IP address and  mounted  direc‐
22              tory  in  host:dir  format.  This  info should not be considered
23              reliable. See the notes on rmtab in rpc.mountd(8).
24
25       -d or --directories
26              List only the directories mounted by some client.
27
28       -e or --exports
29              Show the NFS server's export list.
30
31       -h or --help
32              Provide a short help summary.
33
34       -v or --version
35              Report the current version number of the program.
36
37       --no-headers
38              Suppress the descriptive headings from the output.

BUGS

44       The completeness and accuracy of the information  that  showmount  dis‐
45       plays varies according to the NFS server's implementation.
46
47       Because  showmount  sorts  and  uniqs  the  output, it is impossible to
48       determine from the output whether a client is mounting the same  direc‐
49       tory more than once.
50
51       showmount  works  by  contacting  the  server's  MNT  service directly.
52       NFSv4-only servers have no need to advertise their exported root  file‐
53       handles  via  this  method,  and  may  not  expose their MNT service to
54       clients.
