Chapter 3. Configuring the Network

Before you power up for the first time, you should you fill out the information required for the Appendix B, “Network Connectivity Worksheet”.

Immediately after you power up for the first time, you will be asked if you want to run Linuxconf to set up your networking. You should answer Yes. The curses-based interface to Linuxconf will be invoked.

To use Linuxconf to enter the network connectivity information, do the following:

  1. Press the Tab and Enter keys to quit out of the initial help screen.

  2. Using the arrow keys and the Enter key, open the following tabs in succession:

    Config -> Networking -> Client tasks ->  Basic host configuration

  3. Enter in the appropriate information from your Appendix B, “Network Connectivity Worksheet”.

    The following is an example for a system with two network interfaces, eth0 and eth1. The latter will be used for private networking. The example shows user input in bold; when performing your own configuration, please remember to substitute your own names and IP addresses.


    Note: If you have decided to mount and cable up the system in your production rack, ensure that no one can access eth0 until you are ready to bring the system into full production. The safest ways to do that are as follows:

    • Do not to plug in eth0

    • Do not enable the interface at this time. You can enable eth0 later on when you are ready for it.

  4. Press the Tab key to navigate to the Accept button and then press the Enter key.

  5. Specify the plain host name (up to but not including the first ".") as an alias to your private interface eth1. This enables you to launch the Linuxconf HTTP interface directly from the SGI Internet Server for Messaging Web administration graphical user interface (GUI).

  6. Open the following tabs:

    Config -> Networking -> Client tasks  ->  Name server specification (DNS)

  7. Enter in the server IP addresses from your Appendix B, “Network Connectivity Worksheet”.

    For example:

    +--------------------------------------------------+
    |DNS usage             [X] DNS is required ...     |
    |Default domain                                    |
    |Nameserver 1          1.2.3.254                   |
    |Nameserver 2          1.2.10.254                  |
    +--------------------------------------------------+

  8. Accept your settings by pressing Tab to move to the Accept button and then pressing Enter.

  9. Open the following tabs:

    Config -> Networking -> Client tasks  ->  Routing and gateways -> Defaults

  10. Enter in the gateway IP address from your Appendix B, “Network Connectivity Worksheet”. Do not enable routing; there is normally no reason for a front-end production system to route or forward packets.

    For example:

    +--------------------------------------------------+
    |Default gateway       1.2.3.1                     |
    |Enable routing        [ ]                         |
    +--------------------------------------------------+


    Note: The default gateway device used by Linux is eth0, which is fine in this case.

    However, if you have three or more interfaces, there might be circumstances in which you would want to designate a different physical network port to be the default gateway device. To do this, specify the appropriate value for GATEWAYDEV in the /etc/sysconfig/network file after you have shell access.


  11. Accept your settings.

  12. Quit Linuxconf by using the Tab key to navigate to the Quit button.
