>                 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
>            Priority: Critical
>
> 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.
