GGATEL(8)		  BSD System Manager's Manual		     GGATEL(8)

NAME
     ggatel — GEOM Gate local control utility

SYNOPSIS
     ggatel create [-v] [-o ro | wo | rw] [-q queue_size] [-s sectorsize]
	    [-t timeout] [-u unit] path
     ggatel attach [-v] [-o ro | wo | rw] -u unit path
     ggatel destroy [-f] -u unit
     ggatel list [-v] [-u unit]

DESCRIPTION
     The ggatel utility is a local GEOM Gate class consumer.  It can be used
     as a replacement for md(4) devices or as a “GEOMificator” for non GEOM-
     aware devices, but it was mainly created as an example on how to use and
     how to communicate with the GEOM Gate kernel module.

     Available commands:

     create   Create a ggate provider related to the given regular file or
	      device.

     attach   Attach a worker process to an existing ggate provider.

     destroy  Destroy the given ggate provider.

     list     List ggate providers.

     Available options:

     -f		      Forcibly destroy ggate provider (cancels all pending
		      requests).

     -o ro | wo | rw  Specify permission to use when opening the file or
		      device: read-only (ro), write-only (wo), or read-write
		      (rw).  Default is rw.

     -q queue_size    Number of pending I/O requests that can be queued before
		      they will start to be canceled.  Default is 1024.

     -s sectorsize    Sector size for ggate provider.  If not specified, it is
		      taken from device, or set to 512 bytes for files.

     -t timeout	      Number of seconds to wait before an I/O request will be
		      canceled.	 0 means no timeout.  Default is 30.

     -u unit	      Unit number to use.

     -v		      Do not fork, run in foreground and print debug informa‐
		      tions on standard output.

     path	      Path to a regular file or device.

EXIT STATUS
     Exit status is 0 on success, or 1 if the command fails.  To get details
     about the failure, ggatel should be called with the -v option.

EXAMPLES
     “GEOMify” the “fd0” device and use gbde(8) to encrypt data on a floppy.

	   ggatel create -u 5 /dev/fd0
	   gbde init /dev/ggate5
	   gbde attach ggate5
	   newfs /dev/ggate5.bde
	   mount /dev/ggate5.bde /secret
	   cp /private/foo /secret/
	   umount /secret
	   gbde detach ggate5
	   ggatel destroy -u 5
