Comment 1 Sergey Matveychuk freebsd_committer freebsd_triage 2005-04-09 17:16:55 UTC
It's great, but any reason for use it only for FreeBSD?
Have you tried to send the patch to ISC people?

Hi Dmitry,

i want to take care of your submitted PR ports/79599 for 
net/isc-dhcpd3-server from Wed Apr 06 11:00:15 GMT 2005.

Have you contacted the ISC-DHCP development people to send this patch over 
to them?
I would really like to get this patch into the original ISC-DHCP 
distributions to make it available to the whole community instead of 
having it only locally in the FreeBSD port.

What do you think about this?

regards
Joerg

Hi Sergey,

i've attached a patch to fix PR ports/79599.
After some discussions with the original PR submitter, i decided to let 
him maintain this externally, like the dhcp-ldap patch, and only include 
the necessary bits to get it fetched and included in the build process. 
This way, we do not "pollute" the CVS with this temporary patch, as the 
ISC people decided to include DHCPLEASEQUERY support in the upcoming 
dhcpd-3.1.0 release.

I have tested the port with different OPTION settings on RELENG_4_11, 
RELENG_5_4 and 6.0-CURRENT on i386.

Changelog:
 	- added support for draft-ietf-dhc-leasequery-08.txt
 	  DHCPLEASEQUERY support
 	  Thanks to Dmitry V. Sukhodoev <raven@chics.ru> for providing
 	  this patch
 	- introduced new OPTION to enable DHCPLEASEQUERY support


I will go on now to fix PR ports/76820 and PR ports/76825, as soon as my 
jail is up and running. I have to reproduce and test this for myself as i 
did not received an answer from the PR submitter.

regards
Joerg

I'm sure it's the best decision. I love it.
