This looks like the important bit: Aug 28 11:09:23 guac guacd[775]: guacd[775]: INFO: RDP server closed/refused connection: Server refused connection (wrong security type?) Aug 28 11:09:23 guac guacd[775]: RDP server closed/refused connection: Server refused connection (wrong security type?)
Could you take a look at the workstation's logs around that time and see if it gives any hints. Something like this: $ journalctl --since="2024-08-28 11:00" The logs you posted are hinting at security type being the issue. Double check the connection settings in the Tomcat web UI. My laptop and desktop run Ubuntu so I'll give it a go myself tomorrow, if the helpdesk allows me some respite 8) Cheers Jon On Wed, 2024-08-28 at 15:21 +0000, Randxm wrote: I can RDP in with Remmina no problem. I can also SSH to this ubuntu workstation using Guac without issue. Attached is the debug log. I hope there is nothing in the logs that will doxx me. I appreciate the help on this. I have a few people that rely on this Guac server I've set up.

I just installed 24.04 on a workstation and enabled desktop sharing and remote control. I see the username and password. I set all of this up in Guac but I keep getting the error "RDP server closed/refused connection: Server refused connection (wrong security type?)". Within Guac my settings are fairly simple: Protocol RDP, hostname and port set, username and password set, security type set to Any, Disable authentication unchecked, and ignore server certificate checked. This exact config has worked for me with previous Ubuntu versions. Can somebody point me in the right direction? Are you able to connect using a generic RDP client such as mstsc.exe or xfreerdp? Edit or create /etc/guacamole/guacd.conf: [daemon] log_level = debug See https://guacamole.apache.org/doc/gug/configuring-guacamole.html#configuring-guacd for more details. guacd uses syslog for logging so depending on your distro, you may have to hunt around for the output. Try /var/log/syslog or messages first. Let us know how you get on Cheers Jon --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected]<mailto:[email protected]> For additional commands, e-mail: [email protected]<mailto:[email protected]>
