Normally the DHCP protocol will take care of the settings for you. If you need to configure our card manually then you need to do the following:
File to use:
/etc/network/inferaces – card network configuration settings
/etc/resolve.conf – (DNS server is configured)
bridge-utils – used for bridging multiple inferfaces
ethtool – a program that display and changes Ethenert Card settings such as auto-negatiation, port speed ,duplex mode, and Wake-on-LAN.
The example show as network configuration.
#The primary network inferface
iface eth0 inet static #use ‘auto’ for DCHP
gateway 192.168.0.1 #this might your router at home or 192.168.1.1 is a common configuration used
once this is done.
Before making the next step make sure that you have console access in case you mis configured your network card.
You need to reset reset the card ifdown eth0 && ifup eth0 – runs second command only if the first was successful.
In many Linux distributions the /etc/resolve.conf is still used. Ubuntu team has taken it a bit forward and automate /etc/resolve.conf generation.
To amend an auto-generated list of DNS add the dns configuration to your /etc/network/interfaces configuration by adding the following entry
dns-serach yourdomain.com (This might be useful if you server is added to domain)
dns-nameservers 220.127.116.11 18.104.22.168 #there is space between both addresses.
