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:

Any other ideas?
Thank you, Liz

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.
