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.
