can you plz tell me what is wrong ?
when I send UDP packet to my PC NIC , number of recived packets in ethernet statue window increses and my packet sniffer shows the data correctly but when I sent TCP/SYN(request to send) , while number of recived packets in ethernet statu window increases , sniffer doesnt show anything !!!

You probably took my advice and are using Ethereal...

The sniffer does captures the tcp packets, it's just there is some sort of bug that you can't see the number of captured tcp packets. But once you stop the capture you will be able to see the tcp packets!

Another thing you can do, is to set the Ethereal to show you the packets in real-time. Simply play with the options.

Hard to really tell you without more information. You are opening a connectino right? Can we see the code? You havn't provided enough information to really help you.
