Hi Brian, I experience the same session disconnects you are describing however we do not use no-auth and use various hosts (Windows 7, Windows Server 2008 R2 and 2012 R2). We do have RDP policies configured to keep the disconnected sessions running like in your scenario, however in your case, check the policy that kicks and disconnects idle sessions (this will keep the session still running in the background - https://technet.microsoft.com/en-us/library/cc754272(v=ws.11).aspx). Even though we have ensured this policy was configured properly on our servers the sessions still randomly drop (but much less!). We have particularly noted this behavior on slow or unreliable internet connections (like cellphone tethering) and saturated connections (shared wifi at a coffee shop).
The only thing we do that is different than out of the box is utilize mod_proxy and perform SSL on the web browser connection. This is the path: web browser (SSL) -> apache(reverse proxy – non ssl) -> guac daemon (same box) -> RDP hosts both on same segment and remote segments. From what I can tell after doing tcpdumps, the disconnects are due to chrome and how it handles the connection between the guac daemon and the client browser. We have not been able to produce reliable patterns however we are continuing to monitor the service and network.

Once reconnected to the RDP desktop all of the applications are still running. The configuration is setup in a No-Auth configuration which puts the user right at the Windows 2012 R2 login. Once logged into the RDP session, the guac session to the RDP server periodically disconnects at random times with no distinct pattern. The current version of guac running is 0.9.9 on the system. I can get the exact version of web browsers being used but are Explorer and Mozilla. v/r, Brian ________________________________ This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
