Joseph,

If you want to build a display filter, probably the best bet is to use the "_expression_" button near filter entry box and use that to guide you.

TCP port display filters will look something like "tcp.port == 1234" (which include TCP port 1234 as both source or destination port). You can specify these exactly with "tcp.srcport ==1234" or "tcp.dstport == 1234". A range could be specified as "tcp.port >= 6000 && tcp.port <= 10000". You can also specifiy "udp' in the same way.

While this will help isolate the traffic (from other traffic on your network) it doesn't necessarily make your job easier. From a look via Google, it seems that a number of researchers have had a go at trying to decode it, but like any other proprietary and obscure protocol, the job seems pretty difficult when you are only reverse engineering. To be honest unless you are already familiar with how other well know protocols like say HTTP, SSL or RTP work, you are probably facing an uphill job unless you are prepared to put in some long hours.

Regards, Martin

CAN SOME ONE SEND ME A FILTER ALL ABOUT WHAT I HAVE MAKE HERE WITH THE TCP AND UDP BEGIN AND END CAN SOME ONE SEND ME A EXAMPLE OFF _expression_ FILTER
