W406-LX User’s Manual Getting Started
2-6
NOTE SSH provides better security compared to Telnet for accessing the W406-LX’s console utility
over the network.
Configuring the Ethernet Interface
The network settings of the W406-LX can be modified with the Debug Port, or online over the
network.
Modifying Network Settings with the Serial Console Port
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 W406-LX for static or dynamic (DHCP) IP addresses.
Dynamic IP Address
By default, the W406 is configured for dynamic IP addresses. DHCP will assign an IP address
for the W406.
Static IP Address
You may also manually configure the W406 with a static IP address. Four network addresses
must be modified: address, network, netmask, and broadcast.
See the following table for the example.
Default Setting using DHCP Static Setting for LAN (example)
Iface etho0 inet dhcp iface eth0 inet static
address 192.168.3.127
network: 192.168.3.0
netmask 255.255.255.0
broadcast 192.168.3.255
3.
After the boot settings of the LAN interface have been modified, issue the following
command to activate the LAN settings immediately:
#/etc/init.d/networking restart
