Subject RE: Guacamole Dropping Connections
Date Thu, 12 Oct 2017 19:48:55 GMT
Everything looked good when I ran “journalctl –f” below is the output, but the connections
still died. I have another guac that uses version 0.9.10 and I can connect to windows2012r2
just fine which is all I need. Once im in, I can hit 2016 from internal RDP. Log Output=

I tried ssh, to a known good source and it just hangs. Could a ufw firewall be causing some
problems? Do I need to configure anything with the Guacamole Proxy Parameter’s (GUACD).
Or the Remote Desktop Gateway or Preconnection PDU / Hyper-V ?
Just trying to understand whats going on and why it doesn’t work!

Check /var/log/messages or journalctl = see screenshot attached. This is all I have under
/var/log. My Distro is Ubuntu Server 16.04. Any other locations where those guacd logs might
live?


You can check /var/log/syslog.  journalctl is a command, not a file - so you'd just run "journalctl"
at the command line, or "journalctl -f" if you want to tail the file.  I'm not sure if Ubuntu
uses that or not.  The /var/log/syslog file might have information for you.

Alternatively you can start guacd in the foreground with debug:
/path/to/sbin/guacd -L debug -f

(after first stopping/killing any running guacd instances).  That will print out all of the
guacd output to the terminal - then retry your connection and see what errors you get.
