Hi, Your dissector will be called a couple of times to build the various parts of the Wireshark GUI. If the user clicks on a packet it will be called again. So, it all comes down to carefull coding. I can't look at your code, but it may be that you keep state between packets in the dissector, which isn't the way to do it. Thanx, Jaap
_____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Roger Wu Sent: 2008-Jul-25 03:06 To: [email protected] Subject: [Wireshark-dev] interesting issues with multiple calls to dissector I'm working on a dissector for a proprietary protocol, and I'm running into some interesting issues. I'm running on debian 4, with wireshark 0.99.4 (for some legacy reasons). First, I'd like to know if anyone knows why exactly my dissector gets called three times for each single packet. If I just haven't been able to find it in a manual, I'd appreciate anyone pointing out the location. Anyway, due to the triple call, when I try to call a proto_tree_add_text(), I get some asymmetric results, sometimes I get one text item, which is what I wanted, other times, I get 2, which I can't explain. Any ideas? Thanks for your time, Roger
