Z manu:
   ssh [-1246AaCfgKkMNnqsTtVvXxY] .... [user@]hostname [command]

  -s      May be used to request invocation of a subsystem on the remote
              system.  Subsystems are a feature of the SSH2 protocol which
              facilitate the use of SSH as a secure transport for other  
appli-
              cations (eg. sftp(1)).  The subsystem is specified as the  
remote
              command.


Takze bych rekl ze korektni invokace subsystemu je:
ssh -s votruba at 192.168.0.6 test
