thanks :-) I must admit that Stevens says sth about that tool.

But there's still (at least) one thing I don't understand: how to enable
socket debbuging? Is it possible only when socket is created (fe: by some
special system call) ? If yes, does it mean that it depends on the
aplication itself, if it opens its sockets for debbuging and/or if it gives
a command line switch command to turn it on?

any other way to achive the goal? It could be also a kind of dedicated
benchmark tool (lice ttcp) that comes togehter with what i need, I don't
necesarly need to track existing sshd or apache owned sockets.
