Configuring the Ethernet Interface
The network settings of the IA241/240 can be modified with the serial console, or online over the
network.
Modifying Network Settings with the Serial Console
In this section, we use the serial console to configure the network settings of the target computer.
1.
Follow the instructions given in a previous section to access the Console Utility of the target
computer via the serial console port, and then type
#cd /etc/network
to change directories.
2.
Type
#vi interfaces
to edit the network configuration file with vi editor. You can
configure the Ethernet ports of the IA241/240 for static or dynamic (DHCP) IP addresses.
Static IP addresses:
As shown below, 4 network addresses must be modified: address, network, netmask, and
broadcast. The default IP addresses are 192.168.3.127 for LAN1 and 192.168.4.127 for
LAN2, with default netmask of 255.255.255.0.
Dynamic IP addresses
:
By default, the IA241/240 is configured for “static” IP addresses. To configure one or both
LAN ports to request an IP address dynamically, replace static with dhcp and then delete the
address, network, netmask, and broadcast lines.
