I was reading the thread on "Determining IP information for lo" and it reminded of a strange phenomena I noticed on my system. The laptop I am using now, which should be 192.168.2.11 (according to /etc/hosts) has been given the address 192.168.2.101, although I don't see any mention of this address anywhere on the desktop running dhcpd, or on the laptop, except in /var/lib/dhclient/dhclient-eth0.leases . (The correct MAC address for the laptop, and its desired IP address, is given in /etc/dhcpd.conf , but for some reason this is ignored.) I should say that WiFi works perfectly well with this wrong address. But it has made me realize that I am very hazy about how dhcp works, and how exactly dhcpd determines the addresses it will give out. Is there a reasonably clear account of this anywhere? I saw incidentally that something or someone (I assume a yum update) had moved /etc/dhclient.conf to dhclient.conf.bak , just leaving what looked like a fairly useless dhclient.conf.sample , confirming my view that the people who write sample files for Fedora are somewhat lacking in common sense.
