| 5124214b | 12 | A VPN tunnelling system based on userv ipif, which does encryption |
| 13 | and can be used to join two hosts or whole networks. It uses its | |
| 14 | own nonstandard protocols, not IPSEC. Key setup is done via an ssh | |
| 15 | connection, and actual data packets are sent (encrypted) using UDP. | |
| 16 | With the appropriate configuration in userv ipif, users can be | |
| 17 | allowed to create VPN connections without needing root privilege. | |
| 18 | ||
