Can't establish connection [solved]

[Gul Dukat]

Hi,

 

I've recently installed "Thor" and after that "Odin" on one of my test-configurations. I know about "drakconnect" being broken, and herein is my problem. In my network I'm using static IP-adresses, but with "Thor" and "Odin" I can't seem to get my internet-connection on. The problem is, that it doesn't store/remember my DNS-adresses nor my gateway. It only stores the Ip-adress for this specific configuration and it's subnet. Is there a workaround for this or any other solution for that matter? I've been trying to do a ftp-install, hoping this would be a solution, but I can't seem to find a ftp-iso on any of the mirrors. I hope someone found a solution and could help me out here. I know this bug exists and reported it to Bugzilla, likewise.

 

Thanks in advance.

Have you been configuring your network details from the command prompt? And if so, how were you configuring?

 

The only thing I can think would be configuring if I was using eth0 for example, as follows. I'm going to use example IP's but you'll get the idea.

 

IP: 10.1.1.2

Subnet: 255.255.255.0

Gateway: 10.1.1.1 (router)

DNS: 10.1.1.1 (router)

 

ifconfig eth0 10.1.1.2 netmask 255.255.255.0

 

then:

 

route add default gw 10.1.1.1

 

and then:

 

echo "nameserver 10.1.1.1" > /etc/resolv.conf

 

that will overwrite any existing resolv.conf. I don't know if that helps any. And apologies if it sounds like I'm suggesting something you already know ;)

I have to 2 IP-adresses for the DNS-servers. Can I do this twice:

echo "nameserver 10.1.1.1" > /etc/resolv.conf

or will this overwrite the first one? If so, how can I add 2 DNS-servers?

[ianw1974]

You can append to the file using >>. So like this:

 

echo "nameserver 10.1.1.1" > /etc/resolv.conf
echo "nameserver 10.1.1.254" >> /etc/resolv.conf

 

and then the file will have two entries. I'm only using this to create the file rather than vi or anything like that.

Thanks, so far Ian.

Will try this this evening. For now, I'm going to keep my boss happy. ;)

Somehow, this doesn't work. Opening /etc/resolv.conf shows my nameservers and I get a response when I try to ping my gateway. But this doesn't get me on the internet. The settings I've entered, should work to establish an internet-connection.

 

In addition. This what my /etc/resolv.conf looks like:

nameserver 123.456.789.000
nameserver 123.456.789.001

Whats the output of:

 

route

 

or even:

 

netstat -r

 

will produce the same results.

Hi Gul,

 

your first entry for a nameserver is not valid (must be in range 1-254). Make sure you choose a valid DNS server here.

 

(For more info on networking, see http://www.idevelopment.info/data/Networki...ng_Scheme.shtml

 

for example).

He might just have put this as an example, rather than post a legit DNS entry ;)

It is. Sorry, for not making it obvious.

[ianw1974]

Let us know if the route command proves fruitful to one existing for the default gateway.

[Gul Dukat]

Whats the output of:

 

route

Destination	 Gateway		 Genmask		 Flags Metric Ref	Use Iface
10.0.0.0		*			   255.255.255.0   U	 10	 0		0 eth0
169.254.0.0	 *			   255.255.0.0	 U	 10	 0		0 eth0
default		 10.0.0.2		0.0.0.0		 UG	10	 0		0 eth0

or even:

 

netstat -r

 

will produce the same results.

Does:

 

host linux.org

 

resolve to show some sort of internet connectivity?

[Gul Dukat]

Yes it does.

Thanks Ian, for helping me solve this problem. Much appreciated. :)

Uups, should have inspected the numbers more closely! :blush:
