HardenedBSD/usr.sbin/nfsrevoke/nfsrevoke.8
Rick Macklem 03914b0bb2 Add two new utilities and two new daemons to /usr/src/usr.sbin that
are specifically used by the experimental nfsv4 subsystem.
  nfscbd - The NFSv4 client callback daemon.
  nfsuserd - The NFSv4 daemon that maps between user and group name
           and their corresponding uid/gid numbers.
  nfsdumpstate - A utility that dumps out the NFSv4 Open/Lock state.
  nfsrevoke - Administratively revokes an NFSv4 client, releasing all
           NFSv4 Open/Lock state it holds on the server.

.Os
.Sh NAME
.Nm nfsrevoke
.Nd revoke
.Tn NFS
V4 client
.Sh SYNOPSIS
.Nm nfsrevoke
.Ar ClientId
.Sh DESCRIPTION
.Nm
This command is used by a system administrator to revoke a client's access
to the NFS Version 4 server. All Open/Lock state held by the client will
be released.
After revocation, the client will no longer be able to use state on the server
until it does a fresh SetClientID/SetClientIDConfirm operations sequence.
THIS SHOULD BE DONE AS A LAST RESORT ONLY, when clients are holding state
that must be released on the server.
.Pp
The
.Ar ClientId
argument is a hexadecimal string, which is the last field
of the
.Xr nfsdumpstate 8
command's
.Fl o
and
.Fl l
options output.
.Sh SEE ALSO
.Xr nfsv4 4 ,
.Xr nfsdumpstate 8
.Sh HISTORY
The
.Nm
command was introduced as a part of the experimental nfs server subsystem.
