Jimmy Chen created GUACAMOLE-435:
------------------------------------

             Summary: SSH handshake failing
                 Key: GUACAMOLE-435
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-435
             Project: Guacamole
          Issue Type: Bug
          Components: guacamole-docker
    Affects Versions: 0.9.13-incubating
            Reporter: Jimmy Chen
            Priority: Critical


After creating SSH connection configuration to a FreeBSD system, when attempting to access it via Guacamole, it fails to connect. Looking further into the errors being logged. This is shown.

Opening a SSH session to the same system via Putty works perfectly, so it seems like something about guacd is preventing from successful handshake.
