PKTSETUP(1) System Management Commands PKTSETUP(1)
NAME
pktsetup - set up and tear down packet device associations
SYNOPSIS
pktsetup packet_device block_device
pktsetup -d packet_device
pktsetup -s
DESCRIPTION
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 /usr/share/doc/udftools/README.Debian for more information. <>
EXIT STATUS
Pktsetup returns 0 on success, nonzero on failure.
OPTIONS
-d packet-device
Delete the association between the specified packet-device and its block device.
-s Show the current device mapping, one device per line, in the format
name : pktdevid -> blkdevid
(e.g. "0 : 253:0 -> 22:0")
EXAMPLE
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
FILES
/dev/pktcdvd0,/dev/pktcdvd1,... CD/DVD packet devices
