Solution

You can use the command below to change the network settings from Static to DHCP as shown below.
nirtcfg --set section=ETH1,token=dhcpenabled,value=1



You can use the command below to change the network settings for Subnet mask, Gateway, DNS and Link Speed:

• Subnet mask: nirtcfg --set section=ETH1,token=Subnet_Mask,value=255.255.255.0
• Gateway: nirtcfg --set section=ETH1,token=Gateway,value=10.161.81.1
• DNS: nirtcfg --set section=ETH1,token=DNS_Address,value=10.161.81.1
• Link Speed: nirtcfg --set section=ETH1,token=MediaMode,value=100Full (available value is Auto, 100Full, 100Half, 1000Full)

Note: It is compulsory to restart the network after modifying to make sure the network settings are properly configured. You can restart it by using the following command: /etc/init.d/networking restart
