Created attachment 157006 [details] Current "Host Configuration" dialog KRDC handbook is last updated in 2016, and is specifically missing documentation on the SSH tunneling feature. See https://docs.kde.org/stable5/en/krdc/krdc/connection.html. It's also not obvious how the SSH tunnel feature is supposed to be used, so improvements in the interface and documentation are sorely needed. E.g. - What's the "Port" field in the "Host Configuration" dialog used for? The remote SSH port? The local SSH port? - Does KRDC support SSH hosts defined in `~/.ssh/config`? What about pubkey authentication?
