Enabling Audio and/or Drive Breaks RDP
Hello!
We have deployed Guacamole 1.4.0 on a Debian box and we are able to RDP
into remote machines through the web interface, so long as we disable audio
and prevent the ability to transfer files to and from the box.
The lack of audio isn't a huge deal, we don't really expect anyone to watch
the latest Avengers movie via RDP but we do need to be able to send files
to the remote machines.
On the box hosting Guacamole, we made a folder called "share" and (for
troubleshooting at least) set the permission to 777. This is located at
/etc/guacamole/share. Within the web interface, we set the Drive name to
"share" and the drive path to "/home/guacamole" (we also tried
"/home/guacamole/share"). We have tried both automatically creating the
drive and not auto creating it but it doesn't seem to make a difference.
As soon as we try to turn it on, the Guacamole server will connect to the
remote machine (with a black screen) but as soon as the mouse is moved, the
connection is dropped and we get kicked.
The guacamole .so file is where it should be in the freerdp2 folder based
on the guides I've read online. My team and I have spent time reading and
trying everything we can find online regarding these issues but it hasn't
worked unfortunately.
Is this something that any of you amazing people have run into? Any tips.
tricks, guidance, or even just words of encouragement would be great.
Thanks!

Yeah, the core.*.guacd files are the ones that you'd need to dig into, and
you'll want to use gdb to get the back-trace from those files.

Would the problem be found in the logs below? We have continued to
troubleshoot to no avail.

Moved it into debug mode, logs are below. If I had to guess, the
problematic part occurs just before the disconnect.

Re: Enabling Audio and/or Drive Breaks RDP
Posted by "Hankins, Jonathan" <jh...@homewood.k12.al.us>.
FWIW, a few years ago I had a strange crash that was happening with RDP
audio enabled. It turned out that I had some leftover files from a
different version of FreeRDP that were getting loaded when audio was
enabled. Check your ldconfig output and make sure everything looks sane.

Depending on what Linux distribution you're using, abrtd could be
abstracting this away from you. You can try looking through abrtd
and/or "coredumpctl" to see if that shows you where things are kept
and if anything is available.

Thanks Nick, sorry for the delay.
Due to ~reasons~ we had to put the mostly functional Guacamole server into
production so I had to wait for a new machine to be spun up to use for
testing.
Is there a default location where a Guacamole core dump would go? I spent
some time this afternoon looking in locations that seem reasonable, but
none had what I was looking for. /var/lib/systemd/coredump for example was
empty.

Two things stand out to me, here:
* First, you might want to fix the issue with the writable home directory
for the user running guacd. I would recommend just creating a guacd account
with a normal home directory and switching the service over to run under
that account so that FreeRDP can write out the server fingerprints.
* This is likely causing the issues you're seeing:
Oct 21 19:23:21 n114-251-182 guacd[213659]: free(): double free detected in
tcache 2
Oct 21 19:23:21 n114-251-182 coredump_handler: coredump argv[3] is
!usr!local!sbin!guacd
If you could locate this core dump and provide the output, that would help
in tracking it down. It's possible this has already been resolved in the
git version of the code, but if would be good to verify the exact location
of that and make sure that it has actually been resolved.

Re: Enabling Audio and/or Drive Breaks RDP
Posted by Dylan Francis <dy...@gmail.com>.
The logs generated from my most recent connection attempt are below.
It is now creating the user folder within /etc/guacamole/share after I
updated the web ui to /etc/guacamole/share/${GUAC_USERNAME}
There is no guacd user on the machine, if that makes a difference.
I have included the Device Redirection section below as well, if that is
beneficial.

PulseAudio has no bearing on audio for RDP. PulseAudio is used only to
provide audio for VNC, which unlike RDP does not have its own standard for
streaming audio.

Dylan, can you share your guacd logs for when the failure occurs? The log
messages should point to the cause of the behavior you're seeing. Without
the logs, we'll just be blindly guessing.

Hello,
You may want to make sure Pulse audio is installed.
For your file transfer look at the image below, the key here is the ${GUAC_USERNAME} this will create a folder in the path specified for the user account logging in.
Also never use 777 set the permission recursive chmod –R 755 /home/guacamole/share.
Then you will need to make sure the guacd service is owner of the folder path chown –r guacd: /home/guacamole/share
Note the –r maybe –R if you get an error.
Hope this helps.
Thank You

Subject: Enabling Audio and/or Drive Breaks RDP
Hello!
We have deployed Guacamole 1.4.0 on a Debian box and we are able to RDP into remote machines through the web interface, so long as we disable audio and prevent the ability to transfer files to and from the box.
The lack of audio isn't a huge deal, we don't really expect anyone to watch the latest Avengers movie via RDP but we do need to be able to send files to the remote machines.
On the box hosting Guacamole, we made a folder called "share" and (for troubleshooting at least) set the permission to 777. This is located at /etc/guacamole/share. Within the web interface, we set the Drive name to "share" and the drive path to "/home/guacamole" (we also tried "/home/guacamole/share"). We have tried both automatically creating the drive and not auto creating it but it doesn't seem to make a difference.
As soon as we try to turn it on, the Guacamole server will connect to the remote machine (with a black screen) but as soon as the mouse is moved, the connection is dropped and we get kicked.
The guacamole .so file is where it should be in the freerdp2 folder based on the guides I've read online. My team and I have spent time reading and trying everything we can find online regarding these issues but it hasn't worked unfortunately.
Is this something that any of you amazing people have run into? Any tips. tricks, guidance, or even just words of encouragement would be great.
Thanks!

Are there additional logs that could be helpful in determining the
underlying issue?

The box that is running the Guacamole server is Debian and all of the
machines we are trying to connect to are Windows Server 2019 with RDP built
in.

I didn't see a description of the architecture but are you by chance using
xRDP ?
