| 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 | A VPN tunnelling system based on userv ipif, which does encryption | |
| 11 | and can be used to join two hosts or whole networks. It uses its | |
| 12 | own nonstandard protocols, not IPSEC. Key setup is done via an ssh | |
| 13 | connection, and actual data packets are sent (encrypted) using UDP. | |
| 14 | With the appropriate configuration in userv ipif, users can be | |
| 15 | allowed to create VPN connections without needing root privilege. | |
| 16 | ||
| 17 | These tools have only been tested on GNU/Linux, and userv ipif in | |
| 18 | particular uses the Linux-specific `slattach' utility. | |
| 19 | ||
| 20 | ||
| 21 | The documentation available is: | |
| 22 | ||
| 23 | INSTALL | |
| 24 | ||
| 25 | Build and install instructions for both ipif and udptunnel, and | |
| 26 | tutorial on setting up userv ipif and udptunnel in the usual way. | |
| 27 | ||
| 28 | udptunnel (head comment) | |
| 29 | ||
| 30 | Configuration and invocation reference information for the udptunnel | |
| 31 | VPN facility. | |
| 32 | ||
| 33 | service.c (head comment) | |
| 34 | ||
| 35 | Reference information for userv ipif service, including syntax of | |
| 36 | /etc/userv/ipif-networks, and command line arguments to userv ipif. | |
| 37 | ||
| 38 | mech-*.c (head comments) | |
| 39 | ||
| 40 | Detailed specifications of encryption, padding, | |
| 41 | etc. transformations. For use by cryptographers only; otherwise, | |
| 42 | follow the advice elsewhere about what transformations to use. | |
| 43 | ||
| 44 | forwarder.c (head comment) | |
| 45 | ||
| 46 | Underlying UDP forwarding program invocation details. This program | |
| 47 | is normally invoked correctly by `udptunnel'. You should not need | |
| 48 | to read these details unless you are debugging or modifying udptunnel. | |
