Thanks for the quick response @Taddeusz. It appears to have partially worked.  Now the files in the list above are still missing. 

 

 

The only thing I can think to do is remove the container and reinstall using your "my" template.

 

Oh, BTW, the failed message always shows in the Docker log. I don't know why. It always says that but seems to work fine. If you really can't load the login screen there's something else going on.

 

If the page loads but is just a white screen it has to do with database access problems. Could be extensions or libraries in that case. If that is the problem you might post your catalina.out file.

Ahh yes your suggestions helped me figure it out.

 

"If the page loads but is just a white screen it has to do with database access problems. Could be extensions or libraries in that case. If that is the problem you might post your catalina.out file."

 

This is exactly what was happening.  I found in catalina.out that it was an issue with the user mapping.  I had configured LDAP for authentication and mysql for connection definition and management.  After the update, database configuration was not updated because I had both opt_ldap and opt_mysql enabled.  I had to run the container with only opt_mysql, then recreate it with both enabled again and now it works again as expected.

 

I know I am using the container differently than you had designed it.  I appreciate your help it getting it running again.

Interesting. I'm glad I could help you get it working. If you don't mind could you post a sanitized version of your guacamole.properties file? I can test for this myself. What is your LDAP source? I once used LDAP through Windows Active Directory but I had some hardware failure on my domain controller so I decided to just use the built-in MySQL.

This use with Windows AD.  I'll post my sanitized guacamole.properties this evening.  Happy to help any way I can to make this docker better.

I may be doing something wrong but during Duo enrollment i'm not getting the option to add the account to the app? Does anyone have any ideas?

When will this be updated to the latest 0.9.14 release?  Thanks for your work on this!

My Docker is already updated to Apache Guacamole 0.9.14. Are you sure you're using jasonbean/guacamole?

hi, may i ask if there where any changes wich could cause a fast timeout on all kinda connections ?

 

i get a timeout on RDP, VNC, ... after ~ 5 seconds inactivity ... about high latency ...

all telnet sessions doesnt work at all here anymore too, but thats not a big deal here.

 

main start windows stays open, but all remote sessions just gets dropped off real fast ... on 2 different mashines here,

different targets ... RDP to windows, VNC to container, ...

any chance to manually revert back a version ?

To my knowledge there's nothing that would cause this. You can revert to the previous version by specifying the tag "0.9.13". In other words, change the repository to "jasonbean/guacamole:0.9.13" and apply. unRAID will download the older version.

 

If that doesn't fix things you may have a bad network switch or something.

thanks for the reply, didnt change anything, but i forgot  i changed from apache reverse proxy to letsencrypt ...

 

so thats the issue, may anyone with letsencrypt and reverse proxyknows what could be the timeout reaon ?

 

EDIT

 

i guess i got it, buffering OFF in nginx preoxy conf ... my fault, sorry, seems working now again

Check out this page: http://guacamole.apache.org/doc/gug/proxying-guacamole.html

 

You want to make sure you're also proxying Web Sockets.

thanks again for the Tipp

Nginx doesn't automatically proxy web sockets. You have to include the two lines so it will automatically upgrade the connection if a web socket request is received. However, it doesn't need a separate extension like Apache.

 

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;

had that aleady ... thanks for pointing out

I have Guac installed and a Linux VM but for some reason guac cant access the VNC connection. i can vnc to linux but not through guac. I have also tried with and without a password. any ideas?

 

This works in Chorme

http://192.168.0.100/plugins/dynamix.vm.manager/vnc.html?autoconnect=true&host=192.168.0.100&port=5700&path=

 

Also, windows VNC viewer works

 

Guac config

host: 192.168.0.100

port: 5700

pass: blank

 

 docker logs 6e5c1dbf2353

Feb 19 12:10:32 6e5c1dbf2353 guacd[803]: VNC server closed connection

Make sure you put your hostname and port under the "parameters" section. A few versions ago they added a "guacamole proxy parameters" section which confuses some people.

ugh, looks like i have the wrong docker, switching it now.

Is this my Docker? That looks like a REALLY old version. I can't remember how long ago the VNC settings looked like that.

 

Regardless, what does your log output look like from when you attempt to connect?

@Taddeusz  

At the risk of asking the most dumb Q ever... Does this Docker also contain a working Apache server that I can use for web hosting, reverse proxy etc. I could not find one if it does! And is there any noob friendly guide to setting up access to your VMs... I really like the idea of a client-less access to my VMs from my workplace (as they locked out all portable apps and disabled flash for using web client of Teamviewer).   

 

I asked @gridrunner if he might add this to his excellent guides videos but I know he's very busy with a pile of videos already!

 

Thanks for this docker anyway, Meth

No, this Docker does not contain the Apache HTTP Server. You would need to install the separate Apache Server Docker to do reverse proxy and other web hosting duties.

 

The only thing this includes is Apache Tomcat to run the Guacamole Client. Tomcat is built to run Java servlets. It's not designed to fill the duties of the Apache HTTP Server.

Thanks.. well I managed to move to Nginx (finally) since LS.io killed their Apache docker... but I'm definitely going to be trying to get this to work for the remote access

Since you've moved to Nginx here's my reverse proxy settings for my own:

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

location ^~ /guacamole/ {
	proxy_pass http://<replace your ip>:<replace your port>/guacamole/;
	proxy_buffering off;
   	proxy_http_version 1.1;
   	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   	proxy_set_header Upgrade $http_upgrade;
   	proxy_set_header Connection $http_connection;
   	access_log off;
}

The proxy_buffering off is very important if you read their documentation.

Thanks but that breaks my working NGINX with this error: nginx: [emerg] "map" directive is not allowed here in /config/nginx/site-confs/default:31

 

I tried adding map in nginx.conf but its not working for me!

In mine the map directive is at the very top of my default file outside the server directives.
