FIXMOUNT(8)							   FIXMOUNT(8)

NAME
       fixmount - fix remote mount entries

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.

BUGS
       No attempt is made to verify the information in /etc/mtab itself.

       Since  swap file mounts are not recorded in /etc/mtab, a heuristic spe‐
       cific to SunOS is used to determine whether  such  a  mount  is	actual
       (replacing  the	string	"swap" with "root" and verifying the resulting
       path).

       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.
