Woll, ich verwende hierfür "dar" und "openvpn". Auf "openvpn" möchte ich |
| 2 |
an dieser Stelle nicht eingehen, dafür gibt es z.B. |

http://de.gentoo-wiki.com/Openvpn . |

Das folgende Skript ist ein "fire & forget"-Skript; weder dokumentiert, |
| 6 |
noch wirklich zu Ende gebracht. So fehlt z.B. eine Fehlerbehandlung. |
| 7 |
Dafür ist es handlich, erklärt sich fast von selbst ;) , verpackt alles |
| 8 |
in DVD-handliche 2GB-Häppchen und wenn man es richtig steuert, bekommt |
| 9 |
man ein prima "Master-Backup" samt differentiellen Sicherungen zzgl. |
| 10 |
Info-Mail. |

Für Fragen, Ideen und Verbesserungsvorschläge stehe ich gerne zur |
| 13 |
Verfügung... :) |
