I upgraded my wife's 1998 pentium2 desktop from FC1 to FC2, using CDs which a helpful soul had downloaded and burned for me back in February; they had worked then, and FC2 ran fine on my testbed machine, a 1998 pentium2, until the other day when that antique developed hardware trouble.
The install seemed to go fine. When it was done and rebooted, it had saved all the obvious things I looked at, and it let me as root do "up2date yum" and "up2date kernel." Then I did "yum update." That also went fine,
afaict; and since the main object of the upgrade was to get a better version of abiword for the book she's writing, I did "rpm -q abiword" both before and after the yum update; it did change.
Next morning it showed the usual signs of lacking connection: privoxy non-connects, a message from Pine saying "no such host as mail.adelphia.net," etc. But the upstairs machines, on the same router behind the same cable modem, were connecting.
I tried checking the server settings off the main menu; eth0 was not listed.
I tried rebooting, and watching the boot messages. After "enabling loopback interface" it didn't even try to bring up eth0!
I tried hacking through the internet wizard. That got me to a configuration screen that was already set to use DHCP, but had an IP address in it which I didn't recognize -- it may be the current one to my ISP directly. It certainly isn't one of the form 192.168.20.1xx which the DHCP
in my router uses.
I tried "service network restart," "ifdown eth0," and "ifup eth0" at the behest of someone on a LUG, but none of them helped.
Poking around some more, on the machine I'm using at the moment, which obviously does connect, I get :
=====
[root@localhost btth]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# VIA Technologies|VT6102 [Rhine-II]
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=[MAC address suppressed]
ONBOOT=yes
TYPE=Ethernet
[root@localhost btth]#
=====
I suppose I want to put the likes of that -- with the problem machine's MAC address (which I've forgotten how to ask it for, alas!) on the HWADDR= line -- right? What is that commented-out line on top? Do I need another scrap of info from the other machine there, or should I just omit the line, or ....?
