Routing Problem

gmcle454 · Posted: Thu Mar 25, 2004 1:50 am Post subject: Routing Problem

Ok, so after a BIG SCREW UP, I had to download and compile a new kernel (now 2.6.4). Long story...

I took out one of my nic's and am only using the onboard nic-simpler that way.

I got the back side of my network working. I can ping any machine inside the network. My windows machine is seeing the samba server from my linux box.

So Far So Good.

When I try to ping anything outside the network (ie www.yahoo.com), I get an Unknow host error. So I checked /etc/conf.d/net only to find that the IP, Broadcast IP, Subnet Mask and Gateway were all set correctly.

I'm confused, but that's ok-I'm a n00b. This IS the LEARNING CURVE.

BASIC INFORMATION >>>>>
-Nothing in the kernel is installed as a module
-Untill I get back on the internet, I can't emerge modules-init-tools; and right now I have unmerged modutils. (so don't ask for lsmod :cry:

. . .yet)

-route -n gave me this:

can you ping an IP address? Google is 216.239.37.99. your routing table looks fine, so it's most likely a problem with DNS nameservers. edit your /etc/resolv.conf and verify that you have the correct name servers in there.

Can't ping an outside IP either.

My /etc/resolv.conf file looks like this:

This might help, too

/etc/hosts

My Linux box's IP is 192.168.0.4 - Is this supposed to be in here?

can you give a description of your network setup ... internet connection type ... how the linux box fits in the equation

OK

I'm using a basic router and cable modem for Broadband internet access. This is what my home network looks like.

I'm not sure, my roommate admins the router. I do know that I can't get to the default dns server, though.

if you have a browser you might try putting the gateway adx into the browser adx box to see if you can access it ... are you using the same ip adx that you were before ???

OUTSIDE IP - Probably, but I'm not sure. It only changes every few months.

Inside IP - yes

First, let me say I'm confused about your "new kernel tip" I supposedly provided - I didn't.
All I said was you should rebuild your kernel using the provided .config that comes off the LiveCD, since that's the one genkernel uses.

Not a new kernel - the same one.
With a proven Gentoo-provided kernel .config.

This is to assure that you have all the necessary Ethernet and TCP/IP options set in the kernel.
If that doesn't work, at least we'll know where we stand.

Second - not having lsmod is no problem:

OK. My network is now up and running, but I"m not sure why. All I did was change the IP address. I was using 192.168.0.4, but just for shits and giggles tried changing to 192.168.0.50. I don't know why, but it worked. There are no other machines on my network with that IP address. Any ideas?

possibly a setting within the router ... may not have been nat'ing the address correctly or at all
