Nick Couchman commented on GUACAMOLE-1497:
------------------------------------------

[~joggs]: Yes, the Guacamole project is still active and maintained. The 
mailing list would be a much better place for a spirited and civil discussion 
of your concerns - closed Jira issues are not a great place for this type of 
discussion.

> Gaucamole fails to establish a connection to my piKVM via SSH.
> Guacd reports "SSH handshake failed" in the logs.
> I took a pcap and noticed that the guacamole client seems to only support two 
> server host key algorithms: ssh-rsa and ssh-dss. The ssh server doesn't 
> support either of those two. I infer that this is the cause of the ssh 
> handshake failure. 
> From googling around, openssh no longer supports ssh-rsa so it seems like a 
> deprecation issue. My suggested fix would be for the guac ssh client to 
> support additional server host key algorithms.
> PCAP attached. The client (guac) is 100.76.173.55 and the server is 
> 100.97.86.50.
