Daniel D'Angeli commented on GUACAMOLE-2150:
--------------------------------------------
* Client O/S: Windows 11
* Client Browser: Firefox 143, Chrome 141, Edge 141
* Protocol(s) in use when you see the issue (Kubernetes, RDP, SSH, Telnet,
VNC): SSH
* Remote Server O/S: Ubuntu 22.04 LTS, Ubuntu 24.04 LTS
NOTE: it doesn't seem to happen on Windows 10 when trying to paste on notepad.
I pasted this:
guacamole:
image: guacamole/guacamole: 1.6.0
environment :
- GUACAMOLE_LDAP_ENCRYPTION_METHOD: starttls
The result was as expected:
!image-2025-10-07-16-51-57-522.png!
I suspect the issue is text coming from a different OS then? Maybe something to
do with these options (which are the one im using with the affected target)?
!image-2025-10-07-16-53-19-595.png!
I tried other text like this:
[SMTP-1587]
documentation = *** nota: questo server funziona sia per Office 365 che per
account personali Outlook/Hotmail ***
server_address = smtp.office365.com
server_port = 587
server_starttls = True
local_address = 0.0.0.0 (per consentire richieste da chiunque)
Which gets pasted like this on the ubuntu server:
!image-2025-10-07-16-55-43-369.png|width=857,height=266!
But like this on a windows vm:
!image-2025-10-07-16-56-41-600.png!

> When pasting long text with multiple rows, Guacamole adds an empty line in
> between the rows breaking text formatting. This doesn't happen with
> JumpServer, so it's not browser fault.
> Tried both with Firefox and Chrome, same issue.
> For example, this curl command with multiple rows:
> curl [https://www.google.com|https://www.google.com/] \
> -X GET \
> -H "User-Agent: Mozilla/5.0" \
> -H "Accept: text/html" \
> -L
> Insted of being executed as a single command, is sent to the target as a
> command per row, resulting in the screenshot attached.
> Another example is this docker-compose,yaml file:
> services :
> guacamole:
> image: guacamole/guacamole: 1.6.0
> environment :
> - GUACAMOLE_LDAP_ENCRYPTION_METHOD: starttls
> - GUACAMOLE_LDAP_DISABLE_VERIFY: "true"
> - JAVA_OPTS: "-Djavax. net . ssl . trustStore=/path/to/cacerts -Djavax.
> net. ssl. trustStorePassword=changeit"
>
> This behaviour doesn't allow operators to smoothly work on machines,
> resulting in a turn off of guacamole in our infrastructure and look for other
> solutions.
> Feel free to ask anything if needed.
> Regards,
> Daniel D.
