This is the file to add your:
- static ip address.
- subnet mask.
- broadcast ip address.
If you opted to use dhcp at install, then you’ll see your hostname.if file will contain the single line:
Comment this line out or delete it. Replace it with the following:
inet s.s.s.s m.m.m.m b.b.b.b
- s.s.s.s is your desired ip address, eg. 192.168.0.7
- m.m.m.m is your subnet mast, eg. 255.255.255.0
- b.b.b.b is the broadcast ip address, eg. 192.168.0.255
This the file to add your:
- gateway ip address, eg. 192.168.0.1
If you have only one active interface on your machine, you will need an /etc/mygate file. From the man page:
- If any hostname.if(5) files contain “dhcp” directives, IPv4 entries in /etc/mygate will be ignored.
- /etc/mygate is processed after all interfaces have been configured.
- If /etc/mygate does not exist, no default gateway is added to the routing table.
So, if you’re configuring your sole ethernet interface and you don’t have a wifi interface using dhcp, you’ll need an /etc/mygate file so that a default route is added to the routing table. I learnt this the hard way. I spent a whole weekend trying to figure out why my httpd daemon was not accepting requests forwarded through my modem/router. I didn’t have this file. Once I created it and restarted my network, everything worked.
Once you’ve configured your hostname.if and mygate files, you’re ready to restart your network:
# sh /etc/netstart
