README.DECT

Description:
============
DECT pcap files can be obtained by using tools included with the linux
kernel driver for the Dosch-and-Amand COM-ON-AIR cards. The driver is
called com-on-air_cs.

Wireshark cannot directly record from the DECT HW, as the driver
currently lacks a virtual network interface.

There is ongoing work to change this (see this work by Patrick McHardy):
git clone git://git.kernel.org/pub/scm/linux/kernel/git/kaber/dect-2.6.git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/kaber/libnl-dect.git
git clone git://git.kernel.org/pub/scm/libs/netlink/libnl.git
Also needed are a proper linktype value assigned by the libpcap team and
the proper patches for libpcap to support this (the value used in the
patch below is not officially assigned!):
git://git.kernel.org/pub/scm/linux/kernel/git/kaber/libpcap-dect.git

To nicely view DECT pcap files in wireshark, set up a custom layout:
