unfortunately ssh hangs up after login. Already uninstalled and installed it again. I can fix the issue temporary by erasing ~/.ssh and logoff and login on my system again.

Here is my ssh -v dump:

Does anybody have a clue? 'cause I am clueless...

Thanks in advance

EDIT: Also I want to mention that the terminal seems to hangup completely because Ctrl + C or Ctrl + X don't work.

EDIT2: I also tried ssh -v host ls and the dump looks exactly the same except there is

debug1: Sending command: ls

at the end.
