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
