    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?

    necesarly need to track existing sshd or apache owned sockets.
