card installed. These two machines can be connected directly without a switch (back-to-back),

or both connected to a 10Gb switch. The interfaces have to be declared and configured. The

configuration files for network interfaces on Red Hat Enterprise Linux (RHEL) distributions are

kept under /etc/sysconfig/network-scripts.

5.1. Configuring network-scripts

A typical interface network-script (e.g. eth0) on RHEL 6.0 looks like the following:

# file: /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

HWADDR=00:30:48:32:6A:AA

ONBOOT="yes"

NM_CONTROLLED="no"

BOOTPROTO="static"

IPADDR=10.192.167.111

NETMASK=255.255.240.0

In the case of DHCP addressing the last two lines should be removed and

BOOTPROTO="static" should be changed to BOOTPROTO="dhcp"

The ifcfg-ethX files have to be created manually. They are required for bringing the

interfaces up and down and attribute the desired IP addresses.

5.2. Creating network-scripts

To spot the new interfaces, make sure the driver is unloaded first. To that point ifconfig -a |

grep HWaddr should display all non T4 interfaces whose drivers are loaded, whether the

interfaces are up or not.

On earlier versions of RHEL the NETMASK attribute is named IPMASK. Make

sure you are using the right attribute name.
