run these commands to see the status of your network interface and |
2 |
routing: |
3 |
|
4 |
ifconfig -a |
5 |
netstat -rn |
6 |
|

On a single interface computer it would look like this: |

|

|
10 |
$ ifconfig -a |

If you expect to get a DHPC address and it works, your results should |
39 |
match my sample. If DHCP fails and you need to hardcode your IP |
40 |
address, you should look in the Gentoo Handbook and configure |
41 |
/etc/conf.d/net to support a fixed IP address. |
42 |
|
43 |
If you can configure your IP address but you can't connect outside then |
44 |
your default gateway is probably wrong. In my sample above the |
45 |
important line is the 0.0.0.0, default address, which sends all |
46 |
non-local traffic to 128.95.150.100, which is the default route on my |
47 |
subnet. |
48 |
|
49 |
You can set NET_DEBUG in the /etc/conf.d/net file and run |
50 |
/etc/init.d/net.eth0 start and try to see what fails. |
51 |
|

I hope some of this ramble helps you. Good luck! |
