Specifically, I think the ! >(not) is wrong. No, that code is correct. In a shell script, "if ! arping ..." does not mean "if arping returns 0". It means "if the arping command fails", and "arping -D" gives a failure (i.e., non-zero) return code if it detects a reply. I don't know why you're having a problem. My FC5 test box is set up with a static IP address on its one and only ethernet interface, and that is working fine for me.

I dug a little deeper and found that the ifcfg-eth0 in default had the wrong IP address--one that was actually in use. When I changed that value, all started to work. I really don't know why the ifcfg-eth0 script in /etc/sysconfig/networking/profiles/default is different from that in /etc/sysconfig/network-scripts. In fact, I really don'tunderstand why there are two. Why not symbolic links?

Actually, this was a fresh installation. I had been running Debian before and had reformatted everything but /home.
