Also, there may be something you have to do in the runtime config file to enable the feature also. Be certain to have a good firewall between your host with the sshd remote execution enabled and the dirty world. Anyone that cracks your sshd can run: "rm -fr /" for you. ;) You would probably be better off with tipc: http://tipc.sourceforge.net Mike > On Thu December 18 2008, Herbert Poetzl wrote: > > On Sun, Dec 14, 2008 at 07:15:28AM +0800, LynnOS wrote: > > > Yes,you see my request > > > > > > But why is that impossible? > > > > actually it is quite simple in a secure manner > > (well as secure as accessing the host can get :) > > > > just setup an sshd server on the host, generate > > a key for the guest, add that (preferably with > > a specific command) to the allowed keys on the > > host, and you can execute (predefined) commands > > on the host > > > > ssh also has the provision to pass a shell command > string to the shell invoked by sshd - > similar to the <command string> in: bash -c <command string> > > The caller need not have a login account name on the remote > machine (although they do have to be known to sshd - not > the same thing.
