Winsock RSHD-NT - Version 2.21 A Windows NT/2000/XP version of the Unix Remote Shell Daemon (rshd). It services the standard rsh command, allowing remote command execution of non-interactive programs from Unix, Windows, or other types of systems. It also allows file copies to and from the system via the standard "rcp" command. Security can also be enforced. A special "SendKeys" extension using the standard rsh command allows some remote control of Windows GUI programs executed.
