However, I really didn't want that much software installed, so I tried installing "minimal". I then get: Runlevel is N 3 Network Status reveals three configured devices, and active are "lo eth0" ifcfg-eth0 is as you describe Performing "service network start" and "chkconfig network on" and a reboot did not solve the problem. eth0 had an ipv6 address, but no inet addr, which means it's not going to work in my home network. I then added to the file /etc/sysctl.conf the line: net.ipv6.conf.all.disable_ipv6 = 1 and rebooted. Still no IP address, and when I issued "service network restart" I get: failed: no link present. Check cable? HOWEVER, pulling the ethernet cable and re-inserting it, then issuing "service network restart" got a valid address. After a reboot, again it didn't work. However, after waiting a while, I tried "network start", got some messages about a file existing, and got an IP address. This seems strange. But, the computer is now up and accessing the internet for YUM updates. David
