When I used RedHat Linux 9 before it did. I was puzzled by this at first, since RedHat and FreeBSD both use dhclient (AFAIK), and I spent a few hours looking around for settings for dhclient and found some information about require-hostname, and a few other things. But, no matter what I tried, it didn't seem to work. I continued to look for various articles about dynamic hostname configuration and I am fairly certain I covered the relevant portions of the handbook. Everything I've read seemed to indicate it should "just work", but it wasn't. Finally, after I couldn't find an answer anywhere, I devised my own little hack. I modified /etc/rc.d/hostname like so: hostname_start() { ip=`ifconfig xl0 | grep 'inet ' | awk '{print $2}'` # Set the host name if it is not already set # if [ -z "`hostname -s`" ]; then if [ $ip ]; then hostname=`host $ip | awk '{print $5}'` hostname ${hostname} echo "Setting hostname: `hostname`." fi fi } I then symlinked /etc/rc.d/hostname to /usr/local/etc/rc.d/001.hostname.sh so that after the network interface and everything had been brought up it would set my hostname correctly. I'm sure this is probably an ugly and unnecessary hack, but I could find no other way to get my hostname to be set properly :] I'm quite willing to go debug or rip apart dhclient to figure out why it isn't grabbing the hostname if someone points me in the right direction.
