note that sometimes GSM equipment does add some "private" fields which generates BER_ERROR.

At least the SMSC I'm debuggin now always sends SendRoutingInfoForSM with an additional field which is nowhere in no standard so a BER_ERR shows up. However its not Ethereals' fault.

Hi all,

I’m using 0.99.0 release to decode GSM_MAP signalling on Windowx XP SP2.Logs are collected with Tektronix K15 analyzer. It seems that Ethereal has some bugs on decoding GSM_MAP CheckIMEI message. Here i have attached a sample of pcap file and text output of K15 of the same message.

 

Extra information :

We are using an extension to standard GSM_MAP CheckIMEI message that is the IMSI, which is sent to EIR with CheckIMEI within an extension Tag.Please find it in txt file.

 

Information from Ethereal about box :

Version 0.99.0

 

Compiled with GTK+ 2.6.9, with GLib 2.6.6, with WinPcap (version unknown),

with libz 1.2.3, with libpcre 6.4, with Net-SNMP 5.2.2, with ADNS, with Lua 5.1.

 

Running with WinPcap version 3.1 (packet.dll version 3, 1, 0, 27), based on libpcap version 0.9[.x] on Windows XP SP2, build 2600.
