Thanks Guy, now it's OK. >> 3. Why Ethereal's protocol dissector doesn't recognize Yahoo >> Messenger protocol (YMSG) packets, despite of its presence in >> protocol list?
er> Because those packets either er> 1) aren't being sent to or from the port the dissector thinks er> is the Yahoo port (port 5050) Packets ARE being sent to port 5050. er> 2) aren't at the beginning of TCP segments or don't begin er> with "YPNS" or "YHOO" Yes they are beginning with "YMSG", that means "Yahoo Messenger". And I couldn't find in internet a description of any other Yahoo Messenger protocol, whose packets to begin with "YPNS" or "YHOO". Maybe these ones are too old? >>And if "YMSG" means they >>begin with YMSG, then the reason why the dissector rejects them is >>that nobody's added to the Yahoo Messenger dissector the ability to >>dissect the version of the Yahoo Messenger protocol that uses YMSG. Has anybody in developers team intention to do this? Or one has to do it by himself? WBR, LV.
