OpenSSH_3.8.1p1 on Mac OS X

Subject: OpenSSH_3.8.1p1 on Mac OS X

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 OpenSSH_3.8.1p1

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 Sebastian Wieseler
