Greetings ... I have seen a few times over the period I have been on the list, questions about ddns and rns, and I found something that might help smaller sites tring to get around this problem. I personally found configuring ISC's bind and dhcp less than pretty ( for DDNS and RNS ). I found something that gave me most of what I wanted with very little configuration. The program called dnsmasq at http://www.thekelleys.org.uk/dnsmasq/doc.html Uses your dhcpd.leases file to answers dns and rns requests. I hope this helps someone. Mailed Lee
