#1. Do you have another machine on the local net that you can ping? If so, then you can confirm your NIC / Cable are working and network params are fine. #2. Can you ping an IP address in the outside world? This tests if your firewall / gateway is set up correctly #3. If #2 is okay, can you ping a domain name from the outside world? This tests your DNS settings.

Also, you might want to flush our your iptables because some default rules will block icmp (i.e. ping)

Hi all,

Fairly new to linux and having some problems troubleshooting my internet connection.

For some reason I can't get to the outside world and it's driving me nuts.  I can't ping anything outside my localhost.  I'm running a static IP address:

IP: xx.xx.128.149
Sub: 255.255.252.0
Gateway: xx.xx.128.1

Confirmed with my ISP that those are correct.  I've assigned DNS settings properly and confirmed on another machine that the Gateway, DNS servers are working.

Here is what I've done:

1. Reinstalled Fedora Core 5
2. Turned off the firewall and SELINUX
3. Tried a different network card with same result.

Am I missing something here? Is this some weird DNS issue?

Any help would be great
thanks
