-------------------------------------
Summary: Resizing window causes guacamole to disconnect
Key: GUACAMOLE-2060
URL: https://issues.apache.org/jira/browse/GUACAMOLE-2060
Project: Guacamole
Issue Type: Bug
Affects Versions: 1.6.0
Environment: guacamole server OS: Rocky 9.5
remote server OS: Rocky 9.5
deployment method: docker container
guacamole-server branch: staging/1.6.0
guacamole-client branch: staging/1.6.0
* Both the guacamole server and remote server are on the same private network.
Reporter: Aaron Iles
Fix For: 1.6.0
h1. Build Process
I built the guacd and guacamole images using the corresponding Dockerfiles in
the repos from branches `staging/1.6.0`.
{code:java}
git clone https://github.com/apache/guacamole-server.git
cd guacamole-server
git checkout staging/1.6.0
docker build .
cd ..
git clone https://github.com/apache/guacamole-client.git
cd guacamole-client
git checkout staging/1.6.0
# Had to make a small modification to
guacamole/src/main/frontend/webpack.config.js to disable ClosureWebpackPlugin
to get a successful build
docker build .{code}
Once the images were built I stood up guacamole, guacd, and postgres using the
instructions from the documentation.
h1. Reproducer
# Create an ssh connection in guacamole to any machine (this also happens with
RDP connections)
# Once successfully authenticated and the prompt is visible, resize the
browser in which guacamole is running.
# Wait 15 seconds or so and notice the connection drop with the error
{code:java}
The Guacamole server has closed the connection because there has been no
response from your browser for long enough that it appeared to be disconnected.
This is commonly caused by network problems, such as spotty wireless signal, or
simply very slow network speeds. Please check your network and try again.{code}
If you allow the connection to re-establish, all is well again. Resize the
window again and you may get an error like this
{code:java}
An internal error has occurred within the Guacamole server, and the connection
has been terminated. If the problem persists, please notify your system
administrator, or check your system logs. {code}
