Rsync problem

Hello Newsgroup,
I'm not an network expert.
In our Institut i was able to use rsync with ssh for backup my data from PC to linux server. Since we got a new server the ssh version has changed from ssh1 to ssh2. To access the server I have to use a vpn-client (Cisco VPN-Client 4.0.3).
I'm still able to get an ssh2 connection (only if i force ssh to use keyboard-interactive authentication). rsync is installed on the server as well. But when i try to use rsync with ssh2 i fail. (See my tries below.)
Thank you in advance for every help,
Bernd
