x2go passphrase prompt then authentication fail [closed]

Solution 1:

I know this is a few years old, but I found a solution to the problem here. http://www.procmind.com/blog/2015/11/21/x2go-and-ssh-ecdsa-keys/ It seems the problem is that newer versions of openssh produce an ECDSA key when the following is executed.

ssh-keygen -t rsa

The solution is to create an old-style rsa key like this.

ssh-keygen -m PEM -t rsa -b 4096

So apparently, the new ECDSA keys aren't supported by x2go. Also, I believe the old dsa keys are no longer supported due to security flaws.

Solution 2:

SOLVED: Stupid mistake, I were trying to load a key in .ppk format by specifying it in preferences, the solution, use Pageant and set as "Try autologin" in preferences instead.
