Hello Vincent,

Hello Anders,

 

It looks like we all have a common mother!  J Interesting!

Many thanks for your hints!

Right now have the problem, that we receive a crash on wireshark, when we open the pcap file including one NAS-EPS(LTE) message.

The error message tells us:  “Runtime Error! – Program: C:\Program Files\Wireshark\wireshark.exe – This application has requested the Runtime to terminate it in an unusual way. Please contact the application support team for more information.”

 

What we have done before?

We “captured” a NAS (LTE) message outside of wireshark. This message was just extracted from a trace line, we receive from LTE platform (UE). This NAS message is expected to be correct.

Then we translated this text line (adding  a ‘000000’ in front of the NAS message) to pcap format. We use the command:

"c:\Program Files\Wireshark\text2pcap.exe" -l 147 NAS_message_test_6.txt NAS_message_test_6.pcap

We use a preference setup for the User 0 (DLT-147) and reference to protocol NAS-EPS in wireshark. (User 0 (DLT=147), NAS-EPS,0,””’,0,””

When we start wireshark, we crash.

 

Do we something wrong, or could it be an error?

 

Many thanks!

 

 

Best regards
Karl Heinz Eckstein

Hi,

Both the NAS-EPS dissector and the LTE-RRC dissector are fairly well updated however you need to call them by using a User DLT

or something like that.

Regards

Anders

Hello,

May I ask, which status is applicable on ASN.1, especially dissector of RRC and NAS-EPS.

I’m asking, because I’m trying to dissector a pcap file, which I had generated via text2pcap from a LTE NAS message.

The NAS message is not “decoded”/dissectored by wireshark in my example. But NAS-EPS is available in Filters but not in preferences.

I’m using latest 1.5.1 build.

 

Many thanks for any help about this.

Best regards

Karl Heinz Eckstein
