[X2Go-Dev] X2go Mac client and Red Hat 7 server

[Real, Elizabeth (392K)]

Same error (Protocol Mismatch) even with the 4.0.3.1, 4.0.3.2 and the new
4.0.4.0 OS X 10.9 release.

On the client: I’ve unchecked Media > Sound (enable sound support) and
client side printing support. The Share folders tab did not have any
information other than the ‘use ssh port forwarding to tunnel file system
connections through firewalls’

My session settings are the name, host: ip address, login and ssh port 22.
Session type: XFCE

Here’s the log:
% /Applications/x2goclient.app/Contents/MacOS/x2goclient ; exit;
x2go-INFO-1> "Starting x2goclient..."
x2go-WARNING-1> "Can't load translator: :/i18n/x2goclient_en_us"

2015-05-06 14:52:25.710 x2goclient[11110:826347] modalSession has been
exited prematurely - check for a reentrant call to endModalSession:
x2go-INFO-8> "Starting connection to server: 128.149.23.102:22"
x2go-ERROR-2> "Connection Error(Cannot connect to 128.149.23.102:22):
Protocol mismatch: "


Any other ideas?

Thank you,
Liz
