I have a testbed machine on which I've installed various OSs at various times, including FC6 from the same set of CDs repeatedly. The last couple of installs have refused, adamantly, to connect to the Net -- so adamantly that I had begun to suspect hardware trouble, in the form of some sudden failure of a cable or my ethernet card, but couldn't find it. So I booted up a live CD of Puppy Linux. Once I figured out that I needed to ignore all its dialup stuff and just start with the setup icon, it connected right up. No sweat at all. So I took out the CD and tried again. It still kept telling me device eth0 "seems not to be present." I configured an eth1; trying to activate that got the same result. I've started from the icon, new to me, that looks like a yellow star on a blue balloon, with what might be a mouse at its lower left. Properties for that give a command "/usr/bin/system-config-network" I can get to a box that lets me tell it to obtain IP address settings automatically with dhcp, told it yes, and tried with and without the address of my router. No Joy. The MAC address it has is the one it has always had; but probing claims that doesn't exist. I've tried going to the hosts tab and the edit button, putting in or taking out the IP of the router. No joy. What do I have to do to this thing?? I've never had to do any of this with any of the other machines I've installed FC6 on with these same CDs -- nor 5, or 4, or 3, ... -- nor the first time with this same machine. -- Beartooth Staffwright, PhD, Neo-Redneck Linux Convert Remember I know precious little of what I am talking about.
