Mine include a portion # # Try to start dhclient on Ethernet like interfaces when the link comes # up. Only devices that are configured to support DHCP will actually # run it. No link down rule exists because dhclient automaticly exits # when the link goes down. # notify 0 { match "system" "IFNET"; match "type" "LINK_UP"; media-type "ethernet"; action "/etc/rc.d/dhclient quietstart $subsystem"; }; # notify 0 { match "system" "IFNET"; match "type" "LINK_DOWN"; media-type "ethernet"; action "/etc/rc.d/dhclient quietstop $subsystem ; ifconfig $subsystem inet 0.0.0.0"; }; I am under the impression that this rule does what you want to do.
