RMTAB(4)                                                              RMTAB(4)


NAME
     rmtab - remotely mounted file system table

DESCRIPTION
     Rmtab resides in the 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 of a remotely
     mounted file system.  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 (this is done automatically during system
     startup).  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(1)
     and shutdown(1M).  Starting from IRIX 6.5.27 mountd(1M) can ignore rmtab
     completely and only use the in-core table.

FILES
     /etc/rmtab

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

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