And when you disable file and printer sharing in your X2GoClient's session configuration, the error remains?
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
I’ve attached a screen shot to this message.
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" x2go-WARNING-2> "Can't load translator: :/i18n/qt_en_US" x2go-INFO-3> "Started x2goclient."

Any other ideas?
Thank you, Liz

Weird, I am subscribed but again did not get the notification. Maybe we are blocking your domain.
Called ssh on the command line using the string provided and I logged into my host, no problems. What does this step prove? Other than I¹m using openssh keys to connect?
Did not change the client sshd_config file
We are testing X2go for our Red Hat 7 deployment. We are looking for a low bandwidth remote desktop solution for some of our users.

Stefan,
I did not get notified when you posted your suggestions, either way, which config file on the client does the HostKeyAlgorithms go into?
ssh -o HostKeyAlgorithms=ssh-rsa-cert-v01 <at> openssh.com,ssh-dss-cert-v01 <at> openssh.com,ssh-rsa-cert-v00 <at> openssh.com,ssh-dss-cert-v00 <at> openssh.com,ssh-rsa,ssh-dss yourusername <at> yourhost
By the way, I noticed HostKey /etc/ssh/ssh_host_rsa_key is commented out in the sshd_config on the client, should this uncommented?
Thank you, Liz
You could try (all in one line, no blanks at the mail-client-induced line wraps):
ssh -o HostKeyAlgorithms=ssh-rsa-cert-v01 <at> openssh.com,ssh-dss-cert-v01 <at> openssh.com,ssh-rsa-cert-v00 <at> openssh.com,ssh-dss-cert-v00 <at> openssh.com,ssh-rsa,ssh-dss yourusername <at> yourhost
Oh, darn it. The line wrap looks different in the sent mail than in the compose mail window. Of course, one blank goes behind the "-o", and one before the "yourusername".

Prior to reaching out to the x2godev group, I checked the sshd_config file on the server to ensure the rsa host key was enabled. I restarted sshd anyway, tried connecting from the client to the server but got the same error on the client:

s sh is not working. Can you send me other documentation you may have?
Uhm, no, I don't mean client SSH keys.
If you check /etc/ssh/sshd_config on the RHEL server, you should see a line like "HostKey /etc/ssh/ssh_host_rsa_key"
It may be commented, in the form "#HostKey /etc/ssh/ssh_host_rsa_key"
If it is, please uncomment it (remove the hash) and restart the the SSH daemon:
sudo systemctl restart sshd
After that, try connecting again.
Mihai
