I sometimes need to work on a server which has remote logins disabled for root. Ordinarily I log in, using my own credentials, and then su - to become root once I'm in. Is there any way this can be done through Cyberduck? (I tried issuing su - with the Send Command menu item, but it didn't work.)

Alternatively, some admins disable root logins and add users who need certain root permissions to sudoers. Can Cyberduck prepend "sudo" to commands that require su privileges and prompt the user for a password?

Personally, I prefer the first method as it doesn't entail sending a password every five minutes, although it would require a less-privileged user.
