rmtab(4)                                                 rmtab(4)



     NAME
          rmtab - remotely mounted file system table

     DESCRIPTION
          rmtab resides in directory /etc and contains a record of all
          clients  that  have  done remote mounts of file systems from
          this machine.  Whenever a remote mount is done, an entry  is
          made  in  the rmtab file of the machine serving up that file
          system.  umount removes entries. umount -a broadcasts to all
          servers,  and  informs  them that they should remove all en-
          tries from rmtab created by the sender of the broadcast mes-
          sage.   By  placing  a  umount -a command in /etc/sysinitrc,
          rmtab tables can be purged of  entries  made  by  a  crashed
          host,  which  upon  rebooting  did not remount the same file
          systems it had before.  The table is a series  of  lines  of
          the form

                hostname:directory

          This table is used  only  to  preserve  information  between
          crashes,  and  is read only by mountd(1M) when it starts up.
          mountd keeps an in-core table, which it uses to  handle  re-
          quests from programs like showmount(1M) and shutdown(1M).

     FILES

     BUGS
          Although the rmtab table is close to the truth, it is not
          always 100% accurate.
