People often forget the process for assigning a static IP address from the Linux command line. Most actually feel too intimidated by the process to commit it to memory, but it’s actually very simple. Here’s how to get networking all the way up in a matter of seconds using just three commands.
Step One: Set Your IP Address
ifconfig eth0 192.168.1.5 netmask 255.255.255.0 up
Step 2: Set Your Default Gateway
route add default gw 192.168.1.1
Step 3: Set Your DNS Server
echo "nameserver 22.214.171.124" > /etc/resolv.conf
Assuming you have valid addresses for yourself and your gateway (and you have a clear path the the Interweb) you’re all set. Test by pinging someone.:
