Ran across this installing Red Hat’s free Linux distribution Fedora Core 9 code named Suplhur. Installed totally vanilla install with the GUI anaconda front end. The box sees the NIC, and can ping within the local subnet of the LAN network, but can’t ping out. BTW, it holds a static IP on the network interface card (NIC). Gets the error:

connect: Network is unreachable error

We need to set a default route. Here’s how:

Looked in /etc/sysconfig/network-scripts for the file route-eth0 but it wasn’t there.

Using vi (you can use whichever text editor you prefer) I created that file route-eth0, and put in this one line:

defult via 192.168.0.1

(note: 192.168.0.1 is the LAN IP address of my router. Your router IP address may differ. So you should put in whatever the IP addres of your router is, instead. Most Netgear routers and Qwest DSL boradband modems use 192.168.0.1 and Linksys uses 192.168.1.1 and Belkin uses 192.168.2.1 just to name some common ones.)

Then a simple task of restarting the network and testing:

# service network restart

# ping yahoo.com

Success!

Also, I found that the ethernet adapters weren’t starting automatically. Using the GUI taskbar/ Start Menu, I went into System Administration, then into Services, and enabled the “network” service. Then change runlevel to 3. Ping works so eth0 is up, and that happened at the runlevel change. Change to runlevel 5, test, and… yeppers, it works.
