Hello guys, don't know if this is the right place, but maybe someone can
help me out.

And the server only says to syslog:
sshd[4380]: debug1: Forked child 4381.
sshd[4381]: Connection from $my_child port 49324
sshd[4381]: debug1: Client protocol version 2.0; client software version

sshd[4381]: fatal: Timeout before authentication for $my_client
sshd[4381]: debug1: do_cleanup
sshd[4381]: debug1: PAM: cleanup

This error occours only while my_client=Mac OS X and my_server=Debian
GNU/Linux; the server answers any other session from elsewhere.

But the strange thing is, that a ssh-session from Mac OS X to $the_world
works fine. :-/

Thanks for helping me out
