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
          entries from rmtab created by the sender of the broadcast
          message.  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
          requests from programs like showmount(1M) and shutdown(1M).

     FILES
          /etc/rmtab

     SEE ALSO
          showmount(1M), mountd(1M), mount(1M), umount(1M),
          shutdown(1M).

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