Edit Summary: [SSH Login issue]

  At this time libssh, the ssh library used by X2Go is unable to work with an ECDSA key.
  However you may use an RSA key--if you need to--or go with the SSH default authenticating method using the remote user's password.
  
+ ==== SSH Login issue ====
+ If you already use openssh to get a shell on your x2go server, you may get this message when trying to connect with x2go:  
+ <code>
+ "The host key for
+ this server was not found but an othertype of key
exists. An attacker
+ might change the default server key to confuse your client into thinking
+ the key does not exist"
+ </code>
  
+ This is related to the ECDSA Key (see FAQ above). 
+ To solve this issue, you can disable ECDSA keys on your ssh server configuration, by commenting the following line in /etc/ssh/sshd_config file: 
+ <code>
+ #HostKey /etc/ssh/ssh_host_ecdsa_key
+ </code>
+ Then restart ssh service. 
+ Now you should not get the error message anymore.
