 |
|
I've installed Gentoo now but i have a problem with the network.
I can't ping any other computer.
I've installed support for my network-card in the kernel, and i've done those command-lines:
ifconfig eth0 192.168.0.51 broadcast 192.168.0.255 netmask 255.255.255.0
route add -net default gw 192.168.0.1 netmask 0.0.0.0 metric 1
But, i can't ping.. Why?
(Sorry for my english  )

Is your IP static, or via DHCP? Editing /etc/conf.d/net is probably an easier method. Have you made any changes to that file?

It may be me, but i think there is a problem with your netmask.
| Quote: | ifconfig eth0 192.168.0.51 broadcast 192.168.0.255 netmask 0.0.0.0
route add -net default gw 192.168.0.1 netmask 0.0.0.0 metric 1
|
Is 0.0.0.0 a valid netmask?
Wouldn't a netmask of 255.255.255.0 be more appropriate?
Try this:
| Code: | ifconfig eth0 192.168.0.51 broadcast 192.168.0.255 netmask 255.255.255.0
route add -net default gw 192.168.0.1 netmask 255.255.255.0 metric 1 |

|
But i think we could skipp the route-command because I can't ping any computer.
Any other suggestions?

You did notice that the netmask was different in securiteaze's suggestion for the ifconfig command as well, right?

ohh, sorry. I wrote wrong.
ifconfig eth0 192.168.0.51 broadcast 192.168.0.255 netmask 255.255.255.0
That's my ifconfig.
But it still won't work 
If I boot from the CD, then I can ping any other computer in the network.
But if i start from the HDD, no connection with the subnet. |

Is your NIC up and running? If you do:
Do you get a line that looks something like:
| Code: | | UP BROADCAST NOTRAILERS RUNNING MTU:1500 Metric:1 |
If you don't see that line, your NIC isn't installed properly. Look at dmesg for startup error messages.
Assuming you *do* get that line, then have you looked at the output of ifconfig and route -n when you boot from the CD (which works) compared to when you boot from your hard drive (which doesn't work)?

You boot to the CD and type: "ifconfig" and "route -n" and look at the output...

If not what error do you get?

If mii is support for a NIC card, it would be in the kernel configure options under Network Support (if it is a supported card).

It won't work unless you've compiled it as a module for your kernel. Another alternative is to compile it into your kernel.
You can read the Kernel HOWTO if you're not sure how to do this.

I know how to compile a kernel but I still can't get the network working.
I tried today to install Gentoo 1.4 but the problem is still there.
Please, help me!
If I don't get this issue solved untill the evening. I install Windows, again |

Did you ever do this? If you can ping yourself, but no other hosts, you probably have something hosed with your routing table, like an incorrect netmask.

Listen, I can ping the other computers, IF, i boot from the 1.2-Gentoo-CD( I can't ping the other if I boot from the 1.4CD or my HD).
And, I do the same commands when I boot from the 1.2CD like I do when I try the commands at the HD. |

We are listening. That is why klieber is asking you to run "ifconfig" and "route -n" in both the situation (when booted from the 1.2 CD) and the situation, and to compare the output.

I've got a very similar problem -
I installed Gentoo 1.2, got on th net with no problem, emerged kde
with some problems, and rebooted, now badda-bing, no net!
I tried the CD boot, and still no connection.
Ifconfig shows UP and RUNNING, I think Route is correct. |

- Can you ping localhost
- Can you ping your own IP address?
- Can you ping your default gateway IP address?

Let s make it simple. Copy the following to /etc/conf.d/net
| Code: |
iface_eth0="192.168.0.51 broadcast 192.168.0.255 netmask 255.255.255.0"
gateway="eth0/192.168.0.1"
|
Then, restart your computer, log in as root and run
| Code: |
/etc/init.d/net.eth0 start
|
And then tell us if there is any error. |

I've done that and I get no errors. And the route-command gives the output: UP RUNNING
I've done rc add net.eth0 default so that starts automaticly.
Any more suggestions? |
