|
|
* Subject: [tcpdump-workers] request for LINKTYPE_
|
|
*
|
|
* We've had some discussion over on ethereal-dev about a "fake link" or
|
|
* "raw SS7" dissector that allows dumping an arbitrary protocol into a
|
|
* file without any (otherwise necessary) lower level protocols. The
|
|
* common example has been dumping MTP3 into a file without, well, MTP2 or
|
|
* M2PA.
|
|
*
|
|
* We want to store these protocols directly in PCAP file format because
|
|
* it's well defined and there isn't another (popular) file format for
|
|
* capturing SS7 messages that we can reverse engineer (and we want to read
|
|
* these files into Ethereal). Rather than creating a new file format, it's
|
|
* a lot easier to just allocate a LINKTYPE_.
|
|
*
|
|
* Here is the original post thread:

|
*
|
|
* http://ethereal.com/lists/ethereal-dev/200306/threads.html#00200

*

* July's thread on the subject:

|
|
* http://ethereal.com/lists/ethereal-dev/200308/msg00193.html
|
|
*
|
|
*
|
|
* Based on the message in the last URL, I'd like to request a new
|
|
* LINKTYPE_: LINKTYPE_RAWSS7.
|
|
*
|
|
* This packets in this file type will contain a header:
