pktsetup - Man Page

set up and tear down packet device associations


pktsetup packet_device block_device
pktsetup -d packet_device
pktsetup -s


Pktsetup is used to associate packet devices with CD or DVD block devices, so that the packet device can then be mounted and potentially used as a read/write filesystem. This requires kernel support for the packet device, and the UDF filesystem.

See: HOWTO.udf (in the udftools documents directory)

Exit Status

Pktsetup returns 0 on success, nonzero on failure.


-d packet-device

Delete the association between the specified packet-device and its block device.


Show the current device mapping, one device per line, in the format
name : pktdevid -> blkdevid
(e.g. "0 : 253:0 -> 22:0")


The following commands provide an example of using the packet device.

cdrwtool -d /dev/sr0 -q
pktsetup 0 /dev/sr0

mount -t udf /dev/pktcdvd0 /mnt
umount /dev/pktcdvd0
pktsetup -d 0


/dev/pktcdvd0,/dev/pktcdvd1,...  CD/DVD packet devices
