			The libpcap patch is now redundant as the necessary protocol identifiers have been added to libpcap-1.1 by the libpcap maintainers, so libpcap-1.1 is a pre-requisite to use of this patch.

			I have not yet ported the tcpdump patch.

			The main changes are the dissection of KISS & BPQ as separate protocols otherwise there is no change to the supported protocols.

Wireshark (formerly known as ethereal) is long with [[tcpdump]] the prefered general purpose network protocol analyzer. It's greatest disadvantage for the radio amatuer was the lack of support for [[AX.25]], [[NETROM]] and [[ROSE]], so the only tool left was the special purpse tool listen(8) which pretty much only supports these protocols. Richard Stearn <richard@rns-stearn.demon.co.uk> has provided patches to add support for these protocols to libpcap, wireshark and tcpdump. Below posting is mostly based on his announcements on [[linux-hams]] on 2007-03-18.

These are source code patches. The patches add to:
== libpcap ==
* recognition and capture of AX.25

== tcpdump ==
* decoding AX.25
* extraction from BPQ
* decoding an ARP payload
* decoding a TCP/IP payload
* decoding NetROM
* recognition of Flexnet
* recognition of ROSE

== wireshark ==
* dissection of AX.25
* extraction from BPQ
* extraction from AXIP (untested)
* dissection of ARP payload
* dissection of an TCP/IP payload
* dissection of NetROM
* recognition of Flexnet
* dissection of ROSE
* dissection of "No layer 3" payloads
** APRS (by the book)
** recognition of DX cluster

The dissection of APRS & DX in wireshark is controlled via your preferences:
: Edit->Preferences->Protocols->AX25 No L3

All others are treated as having no L3 protocol and printed in hex and ascii.

The patch is against:
: libpcap-0.9.5
: tcpdump-3.9.5
: wireshark-0.99.5
