  • Server OS = Ubuntu LTS
  • Desktop OS = Windows 7, Ubuntu 12.04.1 LTS
  • DHCP Server daemon = udhcp
  • DNS Server daemon = powerdns (using mysql as the backend)

I am very new to the Linux scene, been playing with it for the past 2 weeks, I have sifted through many web pages and articles and I am extremely impressed and thankful with the Linux community's willingness to share their knowledge.

What I am really battling to find is a website / article that can explain how to setup udhcp so that every time a lease is granted an entry into the dns server is made and when a lease is revoked that entry is then deleted.

It would be appreciated if the answers could include some examples as to how I can implement it.

Thank you Mark Hollander Linux newbie (only for the moment)

Looking at the udhcpd.conf file I see there is an option notify_file. I am presuming that I can place the location to the script to be executed here. If that is the case, how would I know if: 1) udhcpd is assigning a lease or releasing a lease 2) What ip-address and mac-address the action is being performed on. – user108502 Dec 3 '12 at 8:32
I have chosen to abandon this route and go with an article that I have found on the net using the isc-dhcp server instead. I have a few problems with that route which I will post as a new question/thread. – user108502 Dec 3 '12 at 13:32
