Package: x2goclient Version: 4.0.1.2-pre03 Hi Alex, with the latest GSSAPI patch in X2Go Client, I observe the following: Session profile options: autologin = false krblogin = true If GSSAPI fails, the underlying ssh process falls back to SSH-key based authentication. When this happens on passphrase protected SSH keys, I see this when running X2Go Client from the command line: """ mike@:~$ LANG=C x2goclient x2go-INFO-1> "Starting x2goclient..." x2go-WARNING-1> "Can't load translator: :/x2goclient_c" x2go-WARNING-2> "Can't load translator: :/qt_C" x2go-INFO-3> "Started x2goclient." x2go-INFO-8> "Starting connection to server: fylgja.das-netzwerkteam.de:32032" Enter passphrase for key '/home/mike/.ssh/id_rsa': """ ^^^^^^^^^^^^^^^^^^ At this point X2Go Client waits for the input and only continues with SSH key based authentication then (although autologin has been set to false!). Seems like you should limit the ssh subprocess execution to GSSAPIAuthentication only and disable all other auth methods (unless autologin is true).
