Clipboard max size to 256KB on RDP

Manuel Pol
Hi,

Tested on Guacamole 1.2 and 1.1 docker images.

If I copy less than 256KB text from RDP it works fflawlessly:


guacd           | guacd[8]: DEBUG:	Clipboard data received. Reporting availability of clipboard data to RDP server.
guacd           | guacd[8]: DEBUG:	Broadcasting clipboard to all connected users.
guacd           | guacd[8]: DEBUG:	Created stream 0 for text/plain clipboard data.

guacd           | guacd[8]: DEBUG:	Clipboard stream 0 complete.
guacd           | guacd[8]: DEBUG:	Broadcast of clipboard complete.


If I copy more than 256KB text from RDP it doesn't work and guacd don't print anything in log, no warning, no error.

Are there any limits on the clipboard size? Can I increase that limit in any way?
thx!

Does anyone know if there is a 256KB limit on clipboard size?
