Changing IP address in a ArmV7l 3.18.20 embedded Linux distribution

To change the ip address in a ArmV7l 3.18.20 embedded Linux distro, follow these commands:

1. In the embedded equip, check the inferface name using ifconfig. If you're changing the cabled interface, it should be named as eth0;
2. Change the ip address with: sudo ifconfig eth0 192.168.201.105 netmask 255.255.255.0. Change the ip and netmask as needed;
3. Display (route -n) and copy the gateway address of a computer with internet connection;
4. Add the gateway to the device under configuration by using sudo route add default gw 192.168.201.253 eth0;
5. Test the connection via ping google.com

Same steps, but line commands only:

1. ifconfig
2. ifconfig eth0 192.168.201.175 netmask 255.255.255.0
3. (in the configured device) route -n
4. route add default gw 192.168.201.253 eth0
5. ping google.com

Connection via telnet is: telnet 192.168.201.175, root, 1
