This document assumes that you have correctly configured your kernel, its |
| 20 |
|
|
modules for your hardware and you know the interface name of your hardware. |

We also assume that you are configuring <c>eth0</c>, but it could also be |
| 22 |
|
|
<c>eth1</c>, <c>wlan0</c>, etc. |

To get started configuring your network card, you need to tell the Gentoo RC |
| 31 |
jkt |
1.5 |
system about it. This is done by creating a symbolic link from |
| 32 |
|
|
<path>net.lo</path> to <path>net.eth0</path> in <path>/etc/init.d</path>. |

Gentoo's RC system now knows about that interface. It also needs to know how |
| 42 |
|
|
to configure the new interface. All the network interfaces are configured in |
| 43 |
swift |
1.2 |
<path>/etc/conf.d/net</path>. Below is a sample configuration for DHCP and |
| 44 |
|
|
static addresses. |

CIDR stands for Classless InterDomain Routing. |
| 66 |
swift |
1.1 |
Originally, IPv4 addresses were classified as A, B, or C. |
| 67 |
|
|
The early classification system did not envision the massive popularity of the |
| 68 |
|
|
Internet, and is in danger of running out of new unique addresses. CIDR is an |
| 69 |
|
|
addressing scheme that allows one IP address to designate many IP addresses. |
| 70 |
|
|
A CIDR IP address looks like a normal IP address except that it ends with a |
| 71 |
|
|
slash followed by a number; for example, 192.168.0.0/16. |
| 72 |
|
|
CIDR is described in <uri link="http://rfc.net/rfc1519.html">RFC 1519</uri>. |

Now that we have configured our interface, we can start and stop it using the |
| 77 |
|
|
below commands |
| 78 |
|
|

When troubleshooting networking, it is recommended to set |
| 87 |
|
|
<c>RC_VERBOSE="yes"</c> in <path>/etc/conf.d/rc</path> so that you get more |
| 88 |
|
|
information about what's happening. |

Now that you have successfully started and stopped your network interface, you |
| 93 |
|
|
may wish to get it to start when Gentoo boots. Here's how to do this. The last |
| 94 |
|
|
"rc" command instructs Gentoo to start any scripts in the current runlevel |
| 95 |
|
|
that have not yet been started. |
