Configuring Ethernet Interfaces

After the first login, you can configure the ioThinx 4530 controller's network settings to fit your application
better. Note that it is more convenient to manipulate the network interface settings from the serial console
than from an SSH login because an SSH connection can disconnect when there are network issues and the
connection must be reestablished.
Modifying Network Settings via the Serial Console
In this section, we use the serial console to configure the ioThinx 4530 controller's network settings. Follow
the instructions in the Connecting to the ioThinx 4530 controller section under Getting Started to access the
Console Utility of the target computer via the serial Console port and then type
change directories.
moxa@Moxa:~$ cd /etc/network/
moxa@Moxa:/etc/network/~$
sudo vi interfaces
Type
ioThinx 4530 controller's Ethernet ports to use either static or dynamic (DHCP) IP addresses.
Setting a Static IP address
To set a static IP address for the ioThinx 4530 controller, use the
gateway, address, network, netmask, and broadcast parameters of the Ethernet interface.
