<para>This section only applies if you're going to configure a network
|
|
card.</para>
|
|
|
|
<para>If you don't have any network cards, you are most likely not going to
|
|
create any configuration files relating to network cards. If that is the
|
|
case, you must remove the <filename>network</filename> symlinks from all the
|
|
runlevel directories
|
|
(<filename class="directory">/etc/rc.d/rc*.d</filename>)</para>

<title>Configuring default gateway</title>
|
|
|
|
<para>If you're on a network you may need to set up the default gateway for
|
|
this machine. This is done by adding the proper values to the
|
|
/etc/sysconfig/network file by running the following:</para>
|
|
|
|
<screen><userinput>cat >> /etc/sysconfig/network << "EOF"</userinput>
|
|
GATEWAY=192.168.1.2
|
|
GATEWAY_IF=eth0
|
|
<userinput>EOF</userinput></screen>
|
|
|
|
<para>The values for GATEWAY and GATEWAY_IF need to be changed to match
|
|
your network setup. GATEWAY contains the IP address of the default
|
|
gateway, and GATEWAY_IF contains the network interface through which the
|
|
default gateway can be reached.</para>

|
<title>Creating network interface configuration files</title>
|
|
|
|
<para>Which interfaces are brought up and down by the network script depends on
|
|
the files in the /etc/sysconfig/network-devices directory. This
|
|
directory should contain files in the form of ifconfig.xyz, where xyz is a
|
|
network interface name (such as eth0 or eth0:1)</para>
|
|
|
|
<para>If you decide to rename or move this /etc/sysconfig/network-devices
|
|
directory, make sure you update the /etc/sysconfig/rc file as well and
|
|
update the network_devices by providing it with the new path.</para>
|
|
|
|
<para>Now, new files are created in that directory containing the following.
|
|
The following command creates a sample ifconfig.eth0 file:</para>
|
|
|
|
<screen><userinput>cat > /etc/sysconfig/network-devices/ifconfig.eth0 << "EOF"</userinput>
|
|
ONBOOT=yes
|
|
IP=192.168.1.1
|
|
NETMASK=255.255.255.0
|
|
BROADCAST=192.168.1.255
|
|
<userinput>EOF</userinput></screen>
|
|
|
|
<para>Of course, the values of those variables have to be changed
|
|
in every file to match the proper setup. If the ONBOOT variable is set
|
|
to yes, the network script will bring it up during the booting of the system.
|
|
If set to anything else but yes, it will be ignored by the network script
|
|
and thus not brought up.</para>
