Uses conf/*.ipconf (static config) and /var/run/service/fw/*.ipconf (dynamic config from dhcp/ppp/vpn/etc) to determine what to do. One-shot-ness of this service means that it shuts itself off after single run. +IOW: it is not a constantly running daemon sort of thing. +It starts, it configures the network, it shuts down, all done +(unlike infamous NetworkManagers which sit in RAM forever, doing hell knows what). However, any dhcp/ppp/vpn or similar service can restart it anytime when it senses the change in network configuration. |
