NETSTART(8) BSD System Manager's Manual NETSTART(8)
netstart - command scripts for network startup
/etc/netstart [interface ...]
netstart is the command script that is invoked by rc(8) during an au- tomatic reboot and after single user mode is exited; it performs network initialization. The netstart script can also be used to start newly-created bridges or interfaces, or reset existing interfaces to their default state. The behaviour of this script is (or can be) controlled to some extent by variables defined in /etc/rc.conf, which specifies which daemons and ser- vices are to be run. During the system boot, netstart is executed. netstart will perform the following operations: • Set the machine's name. • Configure the loopback interface. • Configure all the physical interfaces. • Initialize the routing table and set up the default routes. • Configure all the gif(4) and gre(4) interfaces. • Configure all the bridges. After the system is completely initialized, it is possible to start a newly-created interface or bridge(4), or reset an existing interface to its default state, by invoking sh /etc/netstart foo0 where foo0 is the interface or bridge name.
Routing to the 126.96.36.199/4 net is set up using values from /etc/rc.conf according to these rules: • If the multicast settings are as follows: multicast_host=NO multicast_router=NO then multicast routing will not be enabled. • If the multicast settings are as follows: multicast_host=NO multicast_router=YES then multicast routing will be enabled, but no multicast route will be set up. It is expected that a routing daemon, such as mrouted(8), will be started as well. • If the multicast settings are as follows: multicast_host=YES multicast_router=NO or: multicast_host=foo0 # interface name multicast_router=NO then multicast routing will be enabled, using the default interface, or the interface name specified by multicast_host. • Other cases are configuration errors and will cause multicast routing not to be enabled.
