| | 3 | * userv ipif |
| | 4 | |
| | 5 | A userv service for allowing users to create network interfaces and |
| | 6 | handle the traffic for them. |
| | 7 | |
| | 8 | * udptunnel |
| | 9 | |
| | 10 | This is deprecated. |
| | 11 | |
| | 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 | |
| | 19 | These tools have only been tested on GNU/Linux. |

| | 24 | INSTALL.udptunnel |
| | 25 | |
| | 26 | Build and install instructions for both ipif and udptunnel, and |
| | 27 | tutorial on setting up userv ipif and udptunnel in the usual way. |

| | 29 | udptunnel (head comment) |
| | 30 | |
| | 31 | Configuration and invocation reference information for the udptunnel |
| | 32 | VPN facility. |

| | 35 | |
| | 36 | Reference information for userv ipif service, including syntax of |
| | 37 | /etc/userv/ipif-networks, and command line arguments to userv ipif. |
| | 38 | |
| | 39 | mech-*.c (head comments) |
| | 40 | |
| | 41 | Detailed specifications of encryption, padding, |
| | 42 | etc. transformations. For use by cryptographers only; otherwise, |
| | 43 | follow the advice elsewhere about what transformations to use. |
| | 44 | |
| | 45 | forwarder.c (head comment) |
| | 46 | |
| | 47 | Underlying UDP forwarding program invocation details. This program |
| | 48 | is normally invoked correctly by `udptunnel'. You should not need |
| | 49 | to read these details unless you are debugging or modifying udptunnel. |
