have you, in your professional experience, ever found a traffic where the reserved field was not 0000 ??
That's a field I've never paid much attention to, so I wouldn't be able to say one way or another. I've seen trailers at the end of packets containing random data (or not so random data, such as user data that the server was handling in one way or another). The reserved field is specifically a "MBZ" (Must Be Zero), so it should always be zeros and not random data.
I noticed that in WireShark 1.4 is possible to write a dissector with LUA...is this working well? Seems a great feature to me!
I've never tried using LUA scripting, but I see it mentioned often on the developers mailing list. ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
