This is my port of netkit rsh for Windows. Tested and working under Vista Home Basic and Windows 7 Starter.
Built with MinGW. Source included with the binary. RSH Client For Windows Vista and Windows 7
One of the more frustrating things you'll discover when you upgrade from XP to Vista or Windows 7 is that rsh.exe is gone.....
Why was it removed? Well it wasn't, not entirely at least... Vista Enterprise and Vista Ultimate have an optional Subsystem for Unix-based Applications (SUA) which contain rsh as well as other tools, but only those versions. However if you bought a new laptop or desktop system, chances are it didn't come with Enterprise or Ultimate, but more likely Vista Home Basic, Vista Home Premium, or Vista Business (or a similarly named Windows 7 variant). Evidently, connecting to an rsh server on a linux box isnt something someone at Home or at a Business should do, but only if you're in an Enterprise or reached the Ultimate spending limits of your bank account..
