Hi all!
I'm running C6 (up to date) on x86-64. have been running on the same system for over a year.
a couple of times lately access to the outside network has suddenly stopped working for reasons that I didn't figure out until it happened again yesterday.
I had the time to fool with it, yesterday, so after quite a bit of head-banging I found that it had no default route set up (to make this story less long...).
On CentOs-6 you can set the default route using GATEWAY=aaa.bbb.ccc.ddd either in /etc/sysconfig/network or /etc/sysconfig/network-scripts/ifcfg-X where X is the network interface that you wish to use for default routing, usually eth0. Setting the GATEWAY value in the ifcfg-X file puts it in a place that you are likely to see far more often than /etc/sysconfig/network so the ifcfg-X file is where I usually place it.

actually, GATEWAY is already set in both places. I looked there while the problem was occurring and saw it in both places, and I just looked again and yes, its still there. I am, however, allowing NM to manage the network, and I don't know where it stores its settings.
