Subject: [Etherboot-users] Example ISC DHCP v3 dhcpd.conf using conditional operations
Date: Wed, 13 Jun 2001 20:22:21 -0600
Hopefully someone will find this useful. I spent a long time tracking
down and figuring out all the pieces. To the powers that be, feel free to
stick this in contrib if you like it.
Goal: Use the vendor-class-identifier and ISC DHCP v3 "match" option to
conditionally send proper options only when the DHCP discover/request from
etherboot comes in. We use static-MAC-to-IP mappings for classroom
computers, and dynamic dhcp ranges for other clients (student laptops,
etc).
I used Etherboot 5.0.1 and the patch (required) in this email:
http://www.geocrawler.com/lists/3/SourceForge/5299/0/5952625/
Furture versions of Etherboot will likely already have this patch
included.
