请问linux底下是否有sniffer之类的东西?

答案是肯定的了,那里可以当呢?或者其它类似的网管软件也行
thanks      

Ethereal is a powerful and user-friendly sniffer, usually comes with Linux (I know it comes with SuSe Linux). It runs X windows, and there is another version that does not need X. You need root previlege to run it though. Another tool is tcpdump, which is flexible too, but new users may easily get lost in reading the man-page of it.

Good luck!
