I don't have access to a Windows system.
The system that I am testing is LinuxMint installed in a Docker container.
Maybe this is a problem, however, after installing pulse-audio-module-xrdp (
https://github.com/neutrinolabs/pulseaudio-module-xrdp/wiki/README), I see
that 'pavumeter' is flickering when I play some sound, but I don't hear
anything.
Also, I cannot find the directory '/usr/lib64/freerdp2' on my guacamole
system (which is built on Ubuntu-18.04).

Re: No sound on RDP connection

[Greg_E]

Going to Windows clients I found a different thing to make it work.

After spending a bunch of time in the source files for the server, I found
that the sound routines had been moved to different folders compared to the
previous version. So it really was built correctly.

My fix was to uncheck the "enable audio in console" checkbox in the client
connection settings (in the web interface).

I only have one xrdp client on my network, so I haven't checked to see if
audio works in this client.

Re: Copy/Paste issue

[brian dodds]

Thanks for the response.  A new data point we ran into today, trying to
paste with a ctrl-v resulted in the application we were using on the RDP
host bringing up the 'open file' dialog, and it did it repeatably.  I think
I need to dig more into how all of this works, it's almost as if the ctrl
sequence is sending the wrong keymap - inserting a ctrl-o for some reason.
The ctrl-alt-shift works, but has been deemed too user unfriendly,
unfortunately.  A good sanity check, but not going to cut it for the
final application.  I know these clues aren't well-formed, I'm just hoping
some of these symptoms ring a bell for someone out there.

Brian,

When I tried to replicate your issue just now (Firefox and Waterfox) it 
worked perfectly. The only thing I found was that from M$ Word on the 
remote, with right-click / copy it wouldn't copy/paste, however ctrl-c / 
paste did.


I've not alot to contribute but FYI I have found the _direct_ copy/paste 
to be a bit flaky from time to time. In that instance I've used the 
Guacamole sidebar ctrl-alt-shift; it might be worth seeing if your

the issue is Guacamole <-> Browser, if not then Guacamole <-> target is 
perhaps where to look.


Particularly if the former then maybe you could try a different browser 
to see if the issue continues, I'd probably try it anyway as I think 
this would tend to narrow the field of possible contributory factors.


Otherwise if I notice any issues in the future I'll try the ctrl-c 3x 
and will update if that works and/or I find a solution.

Re: AW: Session timeout

[ivanmarcus]

Ah, thanks Nick, originally I read the question differently. Upon 
re-reading I think I understood the detail incorrectly.


Indeed if the first user *deliberately* logged out, then the second user 
comes along and can log into the original Win session that's a Win issue 
alright.

If a user hasn't correctly logged off then Guacamole has no way of
knowing if there is simply a 'glitch' in internet traffic,
someone's taken a quick break, or whether the user has indeed
gone. Because of this there is a specific session timeout value,
the default is 60 minutes.


It gets a little more complicated than that.  From the original e-mail...

"we have the challenge, that our users use common service accounts to 
login into a windows server with rdp"


So, the users are sharing Windows accounts, which is why one use can 
close/disconnect the Guacamole session and another user can come back 
and log in to that disconnected session and get the same session that 
the previous user had.


Again, I don't think this is a challenge with Guacamole, nor is it 
something that Guacamole can resolve - this sounds to me more like a 
Windows RDP session management issue.

This is described in the manual here: 
https://guacamole.apache.org/doc/gug/configuring-guacamole.html and reads:


api-session-timeout

The amount of time, in minutes, to allow Guacamole sessions 
(authentication tokens) to remain valid despite inactivity. If omitted, 
Guacamole sessions will expire after 60 minutes of inactivity.


From this, and to assist with your problem, I guess you could add the 
'api-session-timeout' parameter to your guacamole properties file and 
reduce the value to a minimal number of minutes, or seconds.


Obviously there is a trade-off, if the connection between guacamole and 
the user is flaky then with reduced timeout that user could be 
forcefully logged off despite being in a valid session. Also (I think) 
if they simply didn't do anything in the session for a period (no 
mouse/keyboard activity) this could also log them off. On this latter 
point I'm a little uncertain as it would depend upon how Guacamole 
determines 'activity', so YMMV...

This works fine and we are happy.

Sometime a user closes the browser without ending the windows

After this the session is not stopped and another user who logs
into guacamole and gets the legacy session of the first user.

Our problem is, the second user is not the first user, and see the
foreign content.

This reconnect is in a timeframe of seconds. We not need a
solution, that act in a timeframe of minutes.

Is it possible to force an automatic logout from the session?

We tried a lot of local policies on windows side. Without success.

Except the api-session-timeout I didn’t find another configuration

How do you handle this without Guacamole?  This doesn't seem to be an issue
with Guacamole so much as it is with Windows session management - that is,
you would have the same issue if your users were using a traditional RDP
client (MS RDP Client) or the Microsoft Web-based RDP gateway?

I don't think Guacamole can necessarily help you with this - since RDP
manages its own sessions, you would have to make sure that the RDP server
is logging the users off as soon as they disconnect.  I believe there are
policies for this that you can enforce in GPO, but it would need to be done
on the Windows side.

Re: No sound on RDP connection

[Greg_E]

I found the same thing with my Windows clients. Upon checking the guacsnd
stuff is missing from the 1.1.0 files, but is included in the 1.0.0 files.
trying to figure out what I need to move from 1.0.0 into 1.1.0 so that I can
make a new client and get this working.

FYI I used the .war file originally to get my system functioning, now I need
to backtrack and figure the rest of the process out. If anyone can lend a
hand to someone who isn't particularly savvy with CentOS, I'd appreciate it.

Second FYI, no problems with audio when I use the Windows RDP client to
connect to my workstations, but obviously getting all my users through a vpn
is not what I want to do, Guacamole looks like what I need to accomplish my
goals in the easiest way for the users to connect.

Copy-paste works fine most of the time, with ctrl-c copying something
inside the target container and having it immediately available on the
client system clipboard to paste. Then something happens to alter this
behavior that I've been unable to identify, and it stops working. But in
troubleshooting the problem I discovered that it still works if I hit
ctrl-c 3 times. If I hit ctrl-c once, the copied text is available inside
the Mate desktop environment but not outside guacamole.  Ctrl-c twice, same
situation.  Ctrl-c 3 times, and now it's available back in the Ubuntu
client! This is pretty repeatable in my production environment, but in my
development environment I still haven't gotten this failure state to happen
in the first place.

Anyhow, any thoughts on what to check or how to debug this issue? The usual
process of restarting services and clearing caches/cookies doesn't seem to
fix this situation, either, at least nothing I've been able to do with
regularity.

Many thanks,
Brian

AW: Session timeout

[Kaminski, Thomas]

Hello Georgi,
thank you for your answer. And yes, this would be a solution, that we internal 
discussed.
This solution force a big change in the eureka connection into our self-made 
identity management system.
I hope to bypass this big workload for my colleagues.

Regards
Thomas

I have a similar problem and for that, I have created different users on 
Windows, so each of the Guacamole users has its own account. But that way they 
will kick each other.

After this the session is not stopped and another user who logs into guacamole

Our problem is, the second user is not the first user, and see the foreign

This reconnect is in a timeframe of seconds. We not need a solution, that act 
in a timeframe of minutes.

Is it possible to force an automatic logout from the session?
We tried a lot of local policies on windows side. Without success.
Except the api-session-timeout I didn’t find another configuration items. And 
this is only for idle session in a unit of minutes.

Hi Juan, 

 

I think you need to create a new file with es.json, just copy and paste the 
en.json file and replace the login notification accordingly.

George

Hey guys, 

 

I have also recently done just this and downloaded from the internet a 
ready-made extension, hereto attached in .zip format. You need to extract all 
the files from it and create a .jar file. You can do that by just executing jar 
-cvf login_customization.jar * in this directory and then placing the jar file 
in the /etc/guacamole/extensions directory, which you might need to create 
first. 

 

You can customize the login message in the translations/en.json file and the 
size of the login box on the web/custom.css. Then you need just to change the 
logos in the web/images directory with your own. I strongly advise you to 
replace the files using the same names and do not edit the path of the logos 
defined in the custom.css file. If I am not mistaken the logo-64.png should be 
the favicon, but better check for yourself. 

 

And I agree with Nick that the customization Wiki page with all available 
options is a great idea. 

 

With regards, 

Georgi

Hi Nick,

thanks a lot – great starting point. I modified your extension and replaced the

Is there any means to use properties defined in guacamole.properties (or

Thanks & Best Regards, Joachim

decisions and sometimes trade-offs. 
What I believe we should agree on is, that it should be easier to customize the 
user interface, no matter what the reason is. I know it is possible to write an 
extension doing that, but an example extension with good documentation would be 
definitely welcome. Right now there are many extensions out for authentication, 
but I am not aware of any that comes without java code but extends the user 
interface, and if only adding a link or overriding an image.

 

https://issues.apache.org/jira/browse/GUACAMOLE-747

 

You're not the first one to ask about that.

 

Does anyone have source code and is willing to share it?

 

I just put together a pull request for the guacamole-client repo that contains 
some example code.  I don't know if/when it will be merged into the repository, 
but you're welcome to take a look at it and see if it's something that helps 
you out:

 

https://github.com/apache/guacamole-client/pull/508

https://github.com/necouchman/guacamole-client/tree/jira/747

 

This branding extension does the following:

- Changes the image used on the logon page

- Changes the title used for the logon page and browser bar

- Adds a warning banner on the logon page directly under the title and above 
the username/password boxes

- Customizes the font used throughout the interface

- Customizes several color schemes used throughout the interface, notably 
headers and buttons

 

Hope it helps.

 

-Nick

file transfer - custom guacamole with angular

[aleksandar89bt]

I'm using guacamole with RDP to make connection to remote dekstop with
angular like frontend. This works fine, but now I have a problem with file
transfer part. "enable-drive" is set to "true" and I have set "drive-path",
virtual drive "G on guacamole RDP" is already created, so is there any way
to make custom upload/download or drag/drop on files with angular using
functionalities of guacamole-client, instead of using existing one with
shortcut CTRL+ALT+SHIFT? The other problem is that "Download" folder which
is created is visible for everyone who is connected on remote desktop, I
want this to be private.
