#ifconfig hme0 plumb
ifconfig -a
hme0: flags=842
inet 0.0.0.0 netmask 0
ether 3:22:11:6d:2e:1f
2. Configuring ipaddress and netmask and making the interface status as up .
#ifconfig hme0 192.9.2.106 netmask 255.255.255.0 up
#ifconfig -a
hme0: flags=843
inet 192.9.2.106 netmask ffffff00 broadcast 192.9.2.255
ether 3:22:11:6d:2e:1f
The file /etc/netmasks is used to define netmasks for ip addresses .
127.0.0.1, is the standard loop back route and 127.0.0.0 is the default loopback ipaddress used by the kernel when no interface is configured this will be the only entry dispalyed by the system on invoking ifconfig -a command..
3. Configuring Virtual interface :
#ifconfig hme0:1 172.40.30.4 netmask 255.255.0.0 up
ifconfig -a
hme0: flags=843
inet 192.9.2.106 netmask ffffff00 broadcast 192.9.2.255
ether 3:22:11:6d:2e:1f
hme0:1: flags=842
inet 172.40.30.4 netmask ffff0000 broadcast 172.40.255.255
4. Ip-forwording :
/etc/rc2.d/S69inet .
#ndd -set /dev/ip ip_forwarding 0
5. Router Configuration
#route add -net 10.0.0.0 -netmask 255.0.0.0 172.40.30.1 1
/etc/defaultrouter.
#route add default 205.100.155.2 1
#route change default 205.100.155.2 1
