Florent,

Are you by any chance capturing ss7 directly using Wireshark?

If so what hardware (ss7 card are you using, OS, etc...)

Thanks

Joe

      Joseph,


You could add your utility in the tools section of the wireshark wiki
http://wiki.wireshark.org/Tools

The datalink value for MTP2 is 140, so as the datalink is already
existing,
you do not need to use a User Datalink.
The value of the datalink are stored in wiretap/libpcap.c, or in the
libpcap sources.

Regards
Florent

Florent,

I already realised that, I have actually written a small utility to ever
come this i.e. to convert from hex text to Wireshark pcap in one go.

Where can I post this for other users with this problem?

One small question why did you specify -l 140 ? Does this indicate MTP2,
I am using -l 147 and then setting the payload to MTP2 under one of the
DLT user settings for 147.

Joe

      Hello,


You have to modify your test file to add an "ascii dump" at each end of
line, and to remove the lines containing a description
(see the attached text file).
Then you will have to convert the file with:
text2pcap -l 140 hex2.txt hex2.cap

The link layer for Gr interface is MTP2.

(See attached file: hex2.txt)(See attached file: hex2.cap)

Florent

Hi,

Totally new to the wireshark product:

I've captured the following on the Gr interface i.e. between the SGSN
and
the HLR on a Nettest MPA 7300 and save the capture as hex only. (file
attached)

I've tried the text2pcap ? l 147 hex.txt hex.cap ( Not sure if this is
what
I should be doing) this creates the hex.cap file.

C:\Programs\Wireshark>text2pcap -l 147 hex.txt hex.cap
Input from: hex.txt
Output to: hex.cap
Wrote packet of 15 bytes at 0
Wrote packet of 15 bytes at 15
Wrote packet of 15 bytes at 30
Wrote packet of 15 bytes at 45
Wrote packet of 15 bytes at 60
Wrote packet of 15 bytes at 75
Read 6 potential packets, wrote 6 packets


I open this file with wireshark, then under DLT user A I select the
DLT=147
and the payload as gsm_map but I get

"DLT User A: No such proto: gsm_map"

How do I go about to decode this file??

Thanks

Joe
