The ,,wrong'' hostname is produced by x2golistsession on the server that the x2gobroker-agent gets executed on. Obviously, your external clients call the X2Go Session Broker. The session broker knows a list of possible hosts for sending the select_session query to. The server that gets asked responds with a hostname from the X2Go session DB, that is not necessarily what you configured in X2Go Session Broker's x2gobroker-sessionprofiles.conf. So, what is needed is a backwards mapping between the result that gets returned by x2gobroker-agent (i.e. the returned server name / hostname) back to the FQDN hostnames configured in X2Go Session Broker. The mapping is not bijective here, it is more about guessing and shooting blindfolded. /me scratches his head on the best approach for this...
