ifconfig gives unknown host error?

I'm not sure what I'm missing. I am getting the error unknown host when I try to use ifconfig to set an ip address.

sudo ifconfig eth0 add 192.168.300.1 netmask 255.255.255.0

returns

192.168.300.1: Unknown host

This seems to be the example command used online. Is there something I'm missing?

The correct command form is

Quote:

sudo ifconfig [interface_name] [IP] netmask [netmask_addresss] broadcast [broadcast_address]

Where did "add" come from?

Did you consult your man page?

Yup, add is in the man page for adding an ip address to an interface. The error was silly. 300 is out of range. Octets only go to 255!

Now "I" feel silly! I read past that twice and read it as 200 both times!
