If I got it right, if I want to utilize file transfer from client browser to RDP host, the only choice for me is SFTP, as RDP Drive allows mapping only Guacamoleserver dirs.
If so, which of the SSH servers is the most preferable (i.e. compatible) for Windows hosts? There are plenty of them, and I assume real practice provides some stats about this.
What shows the most stable work with Guacamole?
