    NAME

    

ggatel

 - GEOM Gate local control utility

 

    SYNOPSIS

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

    DESCRIPTION

    The 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 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, 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
