Problem with File Transfer over RDP
Hello, We have been experiencieng problems when doing file transfer and
printing from a server connected with Guacamole.We have enabled device
redirection and when sending to print a document, the sesión stays waiting
for ever.On the other hand if I try to download a file, the sesión closes
immediately and the explorer Windows opens asking for the path to save the
file and all files downloaded are 4 kb although the original size is bigger.
Once downloaded, the files cannot be opened. I have tested with Chrome,
Mozzilla Firefox and Internet Explorer, Please help me solve this problem,
Best Regards,

Hello Mike,
We tried to install the module you recommended but could not find some of

Re: Problem with File Transfer over RDP
Posted by tedd77 <in...@quantiss.com>.
Hello,
I am encountering an issue with file transfer on Apache guacamole behind a
reverse proxy.
Protocol used RDP, any file size higher than 1M is failing with following
error :
“You do not have permission to upload this file. If you require access,
please check your system settings, or check with your system administrator.”
Being aware of file limitation on guacamole behind an NGINX, increasing the
file size using the client_max_body_size did not help,
Could be that I am not settings in into the right place.
I tried in /etc/nginx/nginx.conf as well as into
/etc/nginx/sites-available/domain_name.conf with no vain.
Tried to follow these links with no results either.
http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/file/t1136/nginx.conf
https://issues.apache.org/jira/browse/GUACAMOLE-1060
Could someone help me solve this issue.
Best regards

Hello Mike,
We have checked all configuration and set nginx.conf according to the
manual, please see the attached file.
After restarting services, Guacamole works normally but still not able to
transfer files.
nginx.conf

Could you please tell us what to do?

Your Nginx configuration doesn't match what we've documented for
setting up Nginx as a reverse proxy for Guacamole:
http://guacamole.apache.org/doc/gug/proxying-guacamole.html#nginx
You should use our documented, known-good configuration as a basis and
move forward from there.
I also notice the following comment in your configuration, right above
where there are a set of configuration lines relevant to WebSocket:
# Enabling websockets using the first 3 lines; Check
/var/log/tomcat8/catalina.out while testing; guacamole will show you a
fallback message if websockets fail to work.
Going forward, you should do as it suggests if things are not behaving
as expected.
Also worth noting, the following pair of lines was within your config:
# Just something that was advised by someone from the dev team;
worked fine without it too.
proxy_cookie_path /guacamole/ /;
Your current configuration does not change the path that Guacamole is
served from. It doesn't make sense to have this line if you are not
changing the path.

Printing via RDP within Guacamole uses the same file transfer mechanism,
yes.

What specific version of Tomcat 7?
Can you share your Nginx configuration?

I might be wrong, but if you don't strictly require file transfers, you can still print by setting up a virtual PDF printer, and I *think* the PDF should be downloaded even if websockets are blocked/disabled.
The local user will then decide what to do with that PDF.

Still haven't been able to make file transfers but I would like to have your

Our Guacamole is installed on Ubuntu, with Tomcat7 and NGINX

For Nginx, all you should need to do is what's documented:
https://guacamole.apache.org/doc/gug/proxying-guacamole.html#nginx
If your configuration already matches the above, and your Nginx supports
WebSocket (1.3 or later), then things should work fine.
Have you tried connecting to Tomcat directly, without any intervening
proxy, to verify that it is indeed the reverse proxy causing trouble? Are
there any other network devices between the users and Tomcat or your proxy
which might not be able to handle WebSocket?

Did you also configure Nginx with SSL/TLS (https) support, and are you
accessing the Guacamole install via https:// instead of http://.

If you installed Nginx you don't need Apache httpd - you only need one or
the other to proxy in front of Tomcat.

Re: Problem with File Transfer over RDP

Hello Mike,
We configured the server.xml with the recommendations on Guacamole Manual
(https://guacamole.apache.org/doc/gug/proxying-guacamole.html) in order to
enable reverse proxy.
We also configured the Nginx sites-enabled/default and still have the same
problem.
Guacamole is running but we cannot find evidence of Apache being installed.
So what can we do in order to transfer and print files ?
Thanks and Regards,
- Sebastian

The module is a requirement. Because of the issue I cited, you will not be
able to print or transfer files unless you configure your reverse proxy to
support WebSocket. The browser will block the transfers if the Guacamole
connection is using HTTP.
... however we found the Catalina.out which I am attaching now:
At this point, any further logs will really just be noise - the cause is
known. You will see errors in your logs, especially with debug-level
logging enabled, just from all the connection closures. If you are using a
reverse proxy and do not configure WebSocket correctly, you will
encounter this issue.

There should be a different log (catalina.out, or possibly via journalctl)
which contains the actual messages, warnings, etc. logged by the Guacamole
web application. This log is the Tomcat access log. That said, this may
already be enough: the fact that there are accesses to the
"/guacamole/tunnel" endpoint (the HTTP tunnel) indicates that WebSocket is
indeed not being used. There is a known issue which prevents file downloads
from functioning correctly while the HTTP tunnel is in use, likely due to
browser limitations on the number of HTTP connections allowed:
https://issues.apache.org/jira/browse/GUACAMOLE-506
I recommend checking whether there is something on the network between your
users and Tomcat which might interfere with WebSocket. A misconfigured
reverse proxy is a common cause.

Do you see any errors or warnings in the guacd or Tomcat logs? In
particular, do you see any warnings in the Tomcat logs about HTTP having to
be used instead of WebSocket? What about any errors in the JavaScript
console of the browser when this occurs? Is there anything on the network
between your users and Tomcat which might be interfering with the
connection?
