[Support] jasonbean - Apache Guacamole

themahbfather · September 6, 2022

Im trying to set up this via docker on my synology. I cannot for the life of me get the default user log in to work. I got the username2 to log in but i cannot figure out what the admin default is. I have legit tried everything. I found the username2 in the user-mapping.xml but doesnt much access. Any where i can find the default info? Its not gaucadmin.

I did find the first user in that usermapping file but when i log in i just get this big red screen

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

with a reconnect and logoff button.

I don't know if the docker imagine is different in synology but the template page for ApacheGuacamole in unRAID says this,

Initial username and password are guacadmin

Are you using the image with or without MariaDB? Unless you’ve set up and manually initialized a separate MariaDB or MySQL database you should be using the image with MariaDB.

im using this: https://registry.hub.docker.com/r/jasonbean/guacamole/

so it is the one with maria db

That doesnt work currently. I try it for the username and password and i get invalid log in as stated above.

This container was designed for use on Unraid. While I know people have used it on other operating systems or NAS’s successfully I don’t own or have access to a Synology NAS.

The only thing I can suggest is looking at the logs to make sure the database is being created and initialized correctly. The only user that should exist after initial start is “guacadmin”. Not sure how “username2” would have ever been created as that’s nowhere in the code.

Another thing you can check is to make sure the PGID and PUID variables are correctly set to match your NAS. If they’re not set properly that could prevent the container from being able to write anything to its “/config” folder.

Thanks, my PGID and PUID are definitely correct because i use those same variables across many other containers without issue but i will double check

It looks like you're using the wrong image tag as I don't see that it's starting mariadb. Make sure you're using jasonbean/guacamole:latest (NOT jasonbean/guacamole:latest-nomariadb). This should be kind of what you should see on the very first start of the container that includes MariaDB:

used a different image ( jwetzell/guacamole) and the logs showed the starting of the db so looks like im in better shape. Thanks!

Taddeusz · September 6, 2022

I realize I've included Microsoft SQL Server support but not PostgreSQL support. I'll be working to correct that oversight for anyone who might wish to use that database over MSSQL or MariaDB/MySQL.

Looks a lot like the problem I described some weeks ago in this forum. I will try the jwetzell container now too.

I've installed guacamole via my docker.
And I am trying to get it behind a revers proxy via NginxProxyManager.

That step fails me until now.
I have set it to the other ip address internally 192.168.2.163, that is the ip where i set Guacamole to and locally that ip address works.
But now Ive set that ip and standard port 8080 as in docker to my NginxProxyManager but, when I am opening it on my subdomain/domain, I get 502 Bad gateway.

What could be the problem here?

Am I right to post the problem here, or do I need to ask this in the NginxProxyManager thread? I really not know.

Hope you'll can help me.

I've set up guacamole behind a reverse proxy via this video:

Hi,

i do have the exact same problem. Did you find a solution?

Yeah, I set my network to bridge and not as shown in the video to proxynet.
So setting your network type of the docker to bridge would work.

Guys is the @hot22shot fix the only answer to get Guac SSH to unRAID when configured on Bridge or Custom docker network??

_______________________________________________________________________________________

So the SSH connection fails because guacd and sshd couldn't find a common ground.

The only way I could make it worked is allowing ssh-rsa again in unraid :

***To permit using old RSA keys for OpenSSH 8.8+, add the following lines to your sshd_config: HostKeyAlgorithms=ssh-rsa,[email protected] PubkeyAcceptedAlgorithms=+ssh-rsa,[email protected]***

hot22shot · November 3, 2022

To my knowledge it's the only fix while we're waiting for Guacamole 1.5 release.

Thank you. Will I need to add these lines after each reboot or is there a way to make changes permanent?

To make it permanent you need to edit the sshd_config file located on your USB key in /boot/config/ssh

For some reason OPT_TOTP has stopped working for me.

When trying to login today I get an error saying the code is incorrect.

After messing around I disabled OPT_TOTP in the docker and could log in.

I created a new "superadmin" user and enabled OPT_TOTP again. When login in with the new user I get asked to scan a QR as per normal. I scan the QR with google authenticator on my phone but again I get an error saying incorrect code.........

Any clue on what has happened as it was working perfectly fine before for over a year.

Is this related to the SSH issue ppl keep discussing in here?

Hi,

I've done a NMAP vulners scan on my network and picking up loads of vulnerabilities in tomcat 8.5.73.

I noticed an update was made in github to automatically use the latest buid of tomcat.

I've deleted my guacamole docker and redeployed, but it is still building with this version of tomcat.

I believe 8.5.83 is now available.

Any hints on how I can get it updated?

Thanks,

CC

This is done at build time. I’ll have to build a new version to update the Tomcat in the container.

nik82 · November 10, 2022

So no one else has problem with OPT_TOTP at the moment?

Only thing I have done lately is upgrading Unraid to the latest version.
