su root

Dieser Teil sollte nicht gemacht werden, wenn man nicht weiß was man da tut!!!
  nano /etc/ssh/sshd_config

  #PermitRootLogin prohibit-password
  in das hier ändern ohne # !!!
  PermitRootLogin yes

  /etc/init.d/ssh restart
  
  Hier wird der root Zugang freigeschaltet, was zu 99,9% nie nötig und gefährlich ist!!!
