Slackware


Open a terminal window also called a console

Type su root and then enter your password

Type vi /etc/rc.d/rc.inet1.conf If there is no vi try pico or nano as the first command

For each device there's a section like the following:

# Config information for eth0: Or whatever the eth may be

IPADDR[0]="" This is where you would enter the ip your trying ot assign it

NETMASK[0]="" Subnet mask goes here

USE_DHCP[0]="" Change this it no if your adding a static setting and to yes if you are removing one

DHCP_HOSTNAME[0]="" Do not touch this it is poison

Now scroll down to the bottom and you will see

# Default gateway IP address:

GATEWAY="" Set your default gateway here
