[X2Go-Dev] Bug#1323: SSH proxy connection doesn't work for tunnel only accounts

Package: x2goclient Version: 4.1.2.1 Tag: patch

I use a ssh proxy server that allows only tunnel connections (i.e. doesn't allow the users to use the shell). After upgrading from Ubuntu 16.04 to 18.04 x2goclient stopped working with my ssh proxy server.

I believe the reason for this is the call to the "checkLogin()" function even for ssh proxy connections (which in my opinion is not necessary).

I attach a patch that makes x2goclient skip the checkLogin() call (as it does for kerberos connections) for the ssh proxy connection.

Thank you for considering this patch.

Kind regards, Arcadie Cracan
