* From: Jeff Morriss <jeff.morriss[AT]ulticom.com>
* To: tcpdump-workers@tcpdump.org
* 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/200307/threads.html#00124
*
* August's thread:
*
* http://ethereal.com/lists/ethereal-dev/200308/threads.html#00193
*
*
* and one of the last messages--which is why I'm mailing you today:
*
* 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:
*/
typedef struct _rawss7_hdr {
/* NOTE: These are in network-byte order. */
guint32 type;
guint16 length;
guint16 spare;
} rawss7_hdr;
/*
*
* followed by protocol data for whatever protocol 'type' indicates.
*
* There was some discussion about these protocol 'type's being allocated by
* tcpdump-workers as well. In fact it would be handy to have one place to
* allocate such numbers, so what do you think about allocating 3 more (for
* now) LINKTYPE_'s:
*/
#define LINKTYPE_RAWSS7_MTP2 140
#define LINKTYPE_RAWSS7_MTP3 141
#define LINKTYPE_RAWSS7_SCCP 142
/*
*
* There is no reason this can't be used to store non-SS7 protocols, but
* it's what we need to use it for now...
*
