NAME

     ggatel -- GEOM Gate local control utility

SYNOPSIS

     ggatel create [-v] [-o ro | wo | rw] [-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.

     -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 informations 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
