-----------------------------------------
Summary: Console codes crashing SSH
Key: GUACAMOLE-681
URL: https://issues.apache.org/jira/browse/GUACAMOLE-681
Project: Guacamole
Issue Type: Bug
Components: SSH
Affects Versions: 0.9.14
Environment: Newest docker versions of guacd and guacamole, running on
Unraid. Client is connecting from Chromium on Arch Linux.
Reporter: Patrick Collins
Based on
[this|https://issues.apache.org/jira/projects/GUACAMOLE/issues/GUACAMOLE-277]
issue, it seems Guacamole is supposed to work with Linux console codes.
I'm getting reliable crashes when printing certain console codes in a Guacamole
SSH session; notably ones printed by .bashrc in [some
configurations|https://github.com/dylanaraps/pywal].
When printed directly on the device, (whether on a tty or a terminal emulator,)
the codes work.
When printed in Guacamole, they immediately crash the session; prompting
reconnection.
This command is enough to crash the session:
{code:java}
echo 1b5d343b0a | xxd -r -p{code}
(It converts some hex to 'ESC []4;' and prints it.)
Apologies if the priority of this issue is inappropriate; I based it off the
"crashes" criterion; but I'm not certain to what extent the program has to
crash to qualify.
