Hi,
I used the Ethereal protocol analyser in workstationA to capture the packet form workstationB, but found packet lost, why ?
Do I have to install the promisculous Network Card in WsA or WsB?
And anybody knows if the Ethereal capture the layer 4 protocols ( like port number of an application ) ? it is because I want to find out the port number of some applications, especially these days, many illegal applications are using port number instead of Layer 3 ?
Or any protocol analyser to capture the layer 3 and layer 4 ?
Thank you Benson
