<title>Configuring default gateway</title>
|

|
|
|
||
|
|
<para>If you're on a network you may need to setup 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>
|
||
|
|
|
||
|
|
<para><screen><userinput>cat >> /etc/sysconfig/network << "EOF"</userinput>
|
||
|
|
GATEWAY=192.168.1.2
|
||
|
|
GATEWAY_IF=eth0
|
||
|
|
<userinput>EOF</userinput></screen></para>
|
||
|
|
|
||
|
|
<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>First let's create this directory by running:</para>
|
||
|
|
|
||
|
|
<para><screen><userinput>mkdir /etc/sysconfig/nic-config</userinput></screen></para>
|
||
|
|
|
||
|
|
<para>Now, new files are created in that directory containing the following.
|
||
|
|
The following command creates a sample ifconfig.eth0 file:</para>
|
||
|
|
|
||
|
|
<para><screen><userinput>cat > /etc/sysconfig/network-devices/ifconfig.eth0 << "EOF"</userinput>
|
||
|
|
ONBOOT=yes
|
||
|
|
DEVICE=eth0
|
||
|
|
IP=192.168.1.1
|
||
|
|
NETMASK=255.255.255.0
|
||
|
|
BROADCAST=192.168.1.255
|
||
|
|
<userinput>EOF</userinput></screen></para>
|
||
|
|
|
||
|
|
<para>Of course, the values of those variables have to be changed
|
||
|
|
in every file to match the proper setup. Usually NETMASK and BROADCAST
|
||
|
|
will remain the same, just the DEVICE and IP variables will change per
|
||
|
|
network interface. If the ONBOOT variable is set to yes, the network script
|
||
|
|
will bring it up during boot up of the system. If set to anything else but
|
||
|
|
yes it will be ignored by the network script and thus not brought up.</para>
