Configuring the Network for Gentoo

tolken3 · n00b Joined: 09 Jan 2003 Posts: 22

I have ran fdisk and setup the partitiions. I am using the stage 3 tarball and i have managed to get it expanded as the install manual has explained but I am having trouble with the network. I have edited the conf file that contains the Domain name and dnsnames and I think thats were something went wrong. I check the file this morning befor I left for work and it contains my doman name and my DNS primary and Secondary but the dnsname for Gentoo sites are gone. I have run ifconfig to check the card and it is up and running so I am sure it is a minor tweak but I must have missed it. Any help or suggestion would be appreciated.

After the network is up, i presume you can ping a random host on the internet, all you have to do is an emerge rsync and continue as the install docs explain...
Asuming you are in your chrooted environment etc.

Thats part of the problem I can ping my NIC and I can ping the gateway but that is where the it stops. Every thing looks good but I can ping a stright IP or a WWW typ address?.

whats your /etc/resolf.conf?
does it contain: Nameserv: ipnumber ?

did you do a "route add default gw 192.168.1.1" or something simular?

what does "netstat -nr" say?

Regards

TaboZ

my resolv.conf contains the folloing lines

Domain : Mydomain.net
Nameserve: Primary DNS IP of my provider
Nameserve: Secondary DNS IP of my provider

I am missing the lines that were there in the original resolv.conf that pointed to the Gentoo Domain name.

I did not do a route add Default gw but, I will give it a try.

nope. All you need are real working nameservers.

Does nslookup work? If it does, try checking your /etc/nsswitch.conf for the hosts line, it should read "files dns".

If it doesn't, post the output of these:

ifconfig -a
netstat
netstat -rn
ping <IP>
traceroute <IP>

For <IP>, try a couple of these Yahoo servers (just to make sure the first one you try isn't temporarily down):
64.58.76.177
64.58.76.178
64.58.76.179

Well, I've done some testing and rebooted a few times...

Meanwhile, I was able to surf this forum form my Windows 2000 box, so router seemed to work a-okay

But DNS didn't seem to work correct here aswell.

FreeSco sort of crashed the DNS server

I rebooted Freesco and now everything works okay!

I have the same problem, I used the script "net-setup eth0". It seems like all the settings are coorect after that. But I can't connect to the internet. I make connection to the internet through a debianserver. The server contains a dhcpserver. I get no error or warning at all.

"ifconfig -a" shows me the the correct ip (192.168.0.4 broadcast 192.168.0.255 netmask 255.255.255.0)
"netstat -rn" (similar to route) shows the correct default gateway

I give the output in win2k from "route print" because its the same as in gentoo:

Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 192.168.0.1 192.168.0.4 1
192.168.0.0 255.255.255.0 192.168.0.4 192.168.0.4 1

I can ping any ip from my lan, but nothing over the internet.

I couldn't test traceroute cause I did't install phase 1 yet. I want the internet working before I continue.

/etc/resolv.conf:
nameserver 195.130.132.17
nameserver 195.130.132.18

We connect to the internet through a proxy. So I exported the PROXYvariables:
export HTTP_PROXY="proxy.pandora.be:8080"
export FTP_PROXY="$HTTP_PROXY"
export RSYNC_PROXY="$HTTP_PROXY"

Still nothing yet.

I see no problem, but it just doesn't work.

Taboz: How do I check if NAT is enabled on the firewall?

Hmm, yes this exact problem we had working on our project at school :S

For me luckily it solved the problem by resetting the NAT/router...

Can you ping outside the network? EG. behind the gateway?
Maybe you can install a Caching DNS on the Gateway and use that?

Well, just a suggestion, I'm as n00b as you are

Just rebooted the gateway, no result.

I cannot ping outside the network, not even the nameservers.

I get the IP though if I ping a webpage: If I ping www.google.com, the IP appears but I don't get any answer.

I think the problem can be the proxy. Because everything works fine in win2k and in any other linux I ever installed (knoppix, redhat, mandrake, peanut).

It seems pretty strange to me, but is "export http_proxy="proxy.pandora.be" the only thing I need to do to configure the proxysettings?

Thanx in advance.
