NETSTART(8) BSD System Manager's Manual NETSTART(8)NAMEnetstart - command scripts for network startup
SYNOPSIS
/etc/netstart [interface ...]
DESCRIPTIONnetstart 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.
MULTICAST ROUTING
Routing to the 224.0.0.0/4 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.
