ok but still i did not get what this routine (capture_mtp2)is used for because libpcap is in charge of the capture and ethreal contains the dissectors for ss7 protocols .
And whether if i have to add similar routines for packet-mtp3.c , packet-tcap.c ......and other ss7 protocols 

Gilbert HOYEK



For Ethereal:

	1) Add a capture_mtp2() routine to epan/dissectors/packet-mtp2.c
2) Add to the switch statement in capture_loop_packet_cb() a case for WTAP_ENCAP_MTP2 to call capture_mtp2().
sorry if i had to send this message to tcpdump because it's the same topic .
I assume you mean here that you're also asking how to add support to tcpdump (if not, the topic isn't exactly the same, so the question should've been asked on ethereal-dev). 

If so, you'd:

	1) write an MTP2 dissector (print-mtp2.c);

	2) add to the "printers[]" array an entry

		#ifdef DLT_MTP2
			{ mtp2_if_print,	DLT_MTP2 },
		#endif

This is the tcpdump-workers list.
