[Support] jasonbean - Apache Guacamole

Message added by Taddeusz,

Before upgrading to 1.5.0 you need to have first upgraded to 1.4.0-3 of the container. I discovered that prior to 1.4.0-3 it was not shutting down MariaDB correctly and causing the database to be left in a dirty state.

 

If after upgrading to 1.5.0 you discover that MariaDB is stopping and the log mentions something about needing to open the database in an older version of MariaDB you should downgrade specifically to 1.4.0-3, start the container and make sure it's running correctly. Then you may upgrade to 1.5.0.

Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, SSH, and Telnet. This docker primarily has a MariaDB (MySQL) database built-in for authentication

We're getting closer to Guacamole 1.5.0. They've released RC1.

Yes, I’ve been working on it when I can.

I did. It made no difference

 

I’m sorry this has happened and sorry to be blunt but are you going to give me something to work with? I can’t help you if you don’t provide me with logs. If you’re worried about privacy then sanitize them or send them to me privately but continuing to tell me over and over that it doesn’t work does nothing.

 

I can tell you from a clean installation it works fine on my end. My production installation has worked fine this whole time. I have nothing to work from and can’t help if you don’t provide me with information.

 

I assume you are on unRAID and checking for updates to make sure you have the latest built image.

Still does not start for me either:

For some reason starting the tomcat service always gives that "failed" message. I haven't been able to figure out why it does that. What does your catalina.out look like? It should be located in ApacheGucamole/guacamole/log.

I've updated the template to make it a privileged container. Tomcat apparently needs this for it to run correctly.

 

I've also updated the image to show more detailed debugging information and prevent the database from being created if the guacamole.properties file doesn't exist.

I've been trying for hours to get this working.  
I was initially able to login with guacadmin/guacadmin and tried to create my first connection.  However, after I clicked on it (the first connection that I setup) to test, I keep getting 

"The remote desktop server is currently unreachable. If the problem persists, please notify your system administrator, or check your system logs."

 

I'm unsure how to find the logs... is that in the appdata folder?

nm, figured it out.  Blew away the entire app and then the app data folder for guac.   It seems if you only create 1 connection AS guacadmin, when you try to login as guac admin it tries to auto-initiate that connection immediately. 

 

Create an additional user for connections and give them permission to connect and only use guacadmin for admin purposes and issues go away.

I'm using Unraid with Nginx reverse proxy, I've spun up VNCWebBrowser and your ApacheGuacamole container.  Everything is communicating, however, I get (frequent) intermittent disconnects when the session is established, seems to happen only when I'm typing or clicking.

 

I've tried using VNC (port 5901) locally, as well as the HTML5 (port 6901), that works fine, its only when I'm accessing that container via ApacheGuacamole that I experience the disconnects.  

 

Not really sure where to go from here, any help would be appreciated.  Please let me know if I can provide anything else.

 

I have 2 different Nginx confs:

I’ve had this happen too when connecting to certain Linux distributions. I’m not sure why it happens. It’s a TLS communication issue between guacd and whatever VNC you’re connecting to. I’ve reported the issue through Apache. They at least know about it. BTW, it also affects their own guacd Docker.

I am having a similar issue with not connecting, but to RDP only (SSH works just fine and the 1 VNC I tried worked as well)

 

Here is the error from Guacamole's interface:

 

"The remote desktop server is currently unreachable. If the problem persists, please notify your system administrator, or check your system logs."

 

 

Here is the log from Unraid (Version 6.5.3)

Here is the output from Catalina.out

I also attached screen shots of the settings for the RDP connection, in case I missed something there. The logs haven't been very helpful from what I can tell as to why it is not connecting.

 

I have also tried to remove the docker and purged its appdata folder accordingly to be a fresh image so that I could make sure that it wasn't something else. Any and all help in fixing this would be appreciated.

Appreciate the fast response. Bummer tho! Glad it's not totally a one off issue.

Great work on the container, thanks again!
