06 Network

Basic Commands

Display Network Settings

  ifconfig

If the command does not work, it's worth trying sudo -u admin ifconfig.

See below for ifconfig example output.

Display Routes

  route

See below for route example output.

View Config File

The current network settings can be viewed directly from the ''ni-rt.ini'' configuration file. It should contain one section per network interface, similar to the following output

[ETH0]
dhcpipaddr=192.168.0.200
dhcpenabled=0
linklocalenabled=0
IP_Address=192.168.0.1
Subnet_Mask=255.255.255.0
Gateway=192.168.0.1
DNS_Address=192.168.0.1
Mode=TCPIP
MediaMode=Auto

For static IP address settings, dhcpenable and linklocalenable need to be set to 0.

Set Persistent IP Address

IP-address change. Static and persistent. From shell/SSH

  nirtcfg --set section=ETH0,token=ip_address,value=192.168.1.5
  nirtcfg --set section=ETH0,token=subnet_mask,value=255.255.255.0
  nirtcfg --set section=ETH0,token=gateway,value=192.168.1.1
  /etc/init.d/networking restart
