Configure Networking

These instructions have been provided to assist with getting networking operational by upon start-up.

By default, if not configured during the installation process, a networking device will need to be enabled toallow a network connection to be active.  The following instructions demonstrate how the network device eth0 (generally the standard wired network connection device) can be enabled upon start-up.

  • Within the Gnome menu, select System > Preferences > Network Connections.


Start up a terminal session (On the Gnome menu, select Applications > System Tools > Terminal) and issue the command system-config-network; - You will be required to enter root password, if don't have super user permissions;

  • Within the network configuration manager, select the appropriate networking device (i.e. eth0) and click on edit;

  • Select the "Activate device when computer starts" option;
    • For those wanting to set a static ip address, you can configure the address in either the IPv4 or IPv6 tabs.

  • Once settings have been entered, Click Apply;
  • Then click on the close button;

Now, next time the computer is restarted, networking should be enabled. You may wish to reboot, to confirm that networking is enabled.

Hosts File

As part of the configuration of the network, where you may have selected to use Static Ip Address and entered the hostname manually, you will mostly likely have to edit your /etc/hosts file.

Note, you only have to edit this file if you are using a static ip address. If you are using DHCP (dynamically assigned IP address) you don't have to worry about editing this file.

It has been found that if you dont make the following changes to the hosts file, the multicast beacon and AGServiceManager will not work correctly.

To edit the file /etc/hosts, type vi /etc/hosts. Make sure you are the super-user while doing this.


If your hosts file looks similar to this: localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
Your IP Address machinename

Change it to read:

Your IP Address machinename localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

Save and exit by hitting the "esc" key then entering :wq.


Example file might look like: jastest localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
