 Posted: Wed Oct 17, 2012 2:33 am Post subject: After install the network not work |
 |
|
I install the version 3.3.8 Gentoo. And follow exactly with the handbook.
While installing, with no DHCP, so I use:
| Code: | ifconfig eth0 192.168.31.112 broadcast 192.168.31.255 netmask 255.255.255.0
route add default gw 192.168.31.1
ifconfig eth0 down
ifconfig eth0 up
|
to set my network. And it works fine.
And I set the /etc/resolv.conf with correct DNS.
I modified the file /etc/conf.d/hostname to change computer name.
Modified the file /etc/conf.d/net with add the following lines:
| Code: | config_eth0=( "192.168.31.112 netmask 255.255.255.0 brd 192.168.31.255" )
routes_eth0=( "default via 192.168.31.1" ) |
And run the cmd line:
| Code: | cd /etc/init.d
ln -s net.lo net.eth0
rc-update add net.eth0 default
|
After the reboot, the network can ping itself with ip 192.168.31.112, but it cannot ping the gateway and any other address anymore.
when i run route, it displayed:
| Code: |
loopback localhost 255.0.0.0 UG 0 0 0 lo
192.168.31.0 * 255.255.255.0 U 0 0 0 eth0 |
I use cmd "route add default gw 192.168.31.1", but it still not work.
And I tried to modify the file "/etc/conf.d/net", change the route part to "routes_eth0=( "default gw 192.168.31.1" )", it still not work.
Please, Please give me some advice. I am not a so good linuxer. |

fakebear,
Check the content of /etc/resolv.conf. If there are no servers listed then add them in /etc/conf.d/net with dns_servers_eth0="8.8.8.8 8.8.4.4"
The above are google's dns servers - you can use them or just replace them with your providers.

Thank you for your answer anyway.
But it is not the problem. Now I cannot ping the gateway with the ip address 192.168.31.1, not associate with the DNS at all. |

Thank you DONAHUE!
After I remove the parens in file "/etc/conf.d/net" and reboot, problem solved.
But after I reboot again, it cannot ping the gateway again. What's the problem? |

ping -c2 192.168.31.1
ping -c2 8.8.8.8
ping -c2 google.com
dmesg | grep -i eth |

Is there any difference between:
| Code: |
routes_eth0="default via 192.168.31.1"
|
and
| Code: |
routes_eth0="default gw 192.168.31.1"
|

IIRC, I have used both with success. Currently I'm using | Quote: | | routes_eth0="default gw 192.168.1.1" |
You may have a loose connection or intermittent problem.
What does say about the nic? manufacturer, model, driver in use?
| Code: | rm /etc/udev/rules.d/70-persistent-net.rules
reboot |
the rule will regenerate on the reboot.
check that /etc/conf.d/net is as you left it.
could there be another 192.168.31.112 on your subnet?

| Having properly configured /etc/resolve.conf, /etc/hosts, and /etc/conf.d/net files is a necessary step towards having a working network. |
