Internet connectivity problem


Hello all, I recently installed fedora core 2 on a dell desktop. Everything works fine and I hard wired my ethernet cable from my gateway(router+mode) to the computer. The machine accepts dhcp ip and I connect to my local lan with no problem.

Issue is: My Fedora box can't find the internet and I have no idea how to start troubleshooting this problem.

Somehow, about 4 laptops get dhcp ip, wireless, connect to both lan and internet without any problem.

Any help would be appreciated.

Thanks in advance.

Fedora 2??? That's ancient...the latest Fedora is 9.

What's the IP address you get from your DHCP server? If it's 169.<whatever>, you probably aren't getting a real address. Type in "ifconfig -a" at a prompt, and you can see what you get.

If you know the address is good, and you can see other machines on your local LAN, you probably aren't getting the correct default route information. The default route depends on how your network is set up, but for most out-of-the-box home networking devices, it's probably 192.168.1.1. You can always type in "route add default gw 192.168.1.1", as root, and see if that works (providing that address is correct).

thanks,
I actually get a real ip address, 192.168.0.5
All the other computers are .3, .2 ... and they all work with internet.

Any guide to troubleshoot this will be very appreciate, thanks

I suggested a command in my first post. Check this page:

for more information.

Unless you have an ancient computer, you'll be much better off installing Fedora 9. Fedora 2 stopped being supported a good few years ago. You'll not get any security updates. And perhaps your internet problem will be solved automatically by installing F9.
good luck

Hey all, I figure that showing my ip tables will help troubleshooting. Btw, my router local ip is 192.168.0.1
below is my routing table

root# /sbin/route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0


Thanks all.
