SYNOPSIS

       fixmount [ -adervq ] [ -h name ] host ...

DESCRIPTION

       fixmount  is  a  variant  of  showmount(8)  that can delete bogus mount
       entries in remote mountd(8C) daemons.  The  actions  specified  by  the
       options are performed for each host in turn.

OPTIONS

       -a -d -e
              These  options  work as in showmount(8) except that only entries
              pertaining to the local host are printed.

       -r     Removes those remote mount entries on host that  do  not  corre-
              spond  to current mounts, i.e., which are left-over from a crash
              or are the result of improper mount protocol.  The actuality  of
              mounts is verified using the entries in /etc/mtab.

       -v     Verify  remote mounts.  Similar to -r except that only a notifi-
              cation message is printed  for  each  bogus  entry  found.   The
              remote mount table is not changed.

       -A     Issues  a command to the remote mountd declaring that ALL of its
              filesystems have been unmounted.  This should be used with  cau-
              tion,  as  it removes all remote mount entries pertaining to the
              local system, whether or not any filesystems are  still  mounted
              locally.

       -q     Be  quiet.   Suppresses error messages due to timeouts and "Pro-
              gram not registered", i.e., due to remote hosts  not  supporting
              RPC or not running mountd.

       -h name
              Pretend  the  local  hostname is name.  This is useful after the
              local hostname has been changed and rmtab entries using the  old
              name  remain  on a remote machine.  Unfortunately, most mountd's
              won't be able to successfully handle removal of such entries, so
              this option is useful in combination with -v only.
              This  option also saves time as comparisons of remotely recorded
              and local hostnames by address are avoided.

FILES

       /etc/mtab           List of current mounts.

       /etc/rmtab          Backup file for remote mount entries on NFS server.

       Symbolic links on the server will cause the path in the remote entry to
       differ from the one in /etc/mtab.  To catch those cases,  a  filesystem
       is  also  deemed  mounted  if its local mount point is identical to the
       remote    entry.     I.e.,    on    a    SunOS     diskless     client,
       server:/export/share/sunos.4.1.1  is  actually  /usr/share.   Since the
       local mount point is /usr/share as well this will be handled correctly.

       There  is  no  way  to clear a stale entry in a remote mountd after the
       local hostname (or whatever reverse name resolution returns for it) has
       been  changed.  To take care of these cases, the remote /etc/rmtab file
       has to be edited and mountd restarted.

       The RPC timeouts for mountd calls can only be changed  by  recompiling.
       The defaults are 2 seconds for client handle creation and 5 seconds for
       RPC calls.
