Script to set up and keep up OpenSWAN ipsec connections

This script connects you to an IPsec RAS service.

It uses FreeS/WAN or openswan connections from ipsec.conf.
These can be monitored, and be rebuild upon failure. For
monitoring, a host on the other side of the tunnel can be pinged.
Optionally, routing settings can be tweaked, a pre-authentication
using opie can be performed or another machine can be remote
controlled.
