* Prepare openSSH to accept sshv1 connections /etc/ssh/sshd_config:

Protocol 1,2

?HostKeys for portocol version 1

?HostKey /etc/ssh/ssh_host_rsa1_key ...
  1. generate rsa1 keyfile 
ssh-keygen -t rsa1 -f /etc/ssh/ssh_host_rsa1_key
  • restart ssh
/etc/init.d/ssh restart

Be sure to have either password, rsa, or tis(?) authentication enabled.


The ssh command never asks for a password itself, but rather asks factotum for the respective credentials. So be sure to have a factotum running, in case of doubt start it with auth/factotum.

The first time you connect to a server, ssh will ask you if you want to store the key or just accept it for this session.
