J'ai been doing certains VM testing. J'ai created et destroyed a large number of VMs on mon subnet to test fresh provisioning via puppet. Cependant, it looks like Ubuntu ne free a DHCP lease quand le system is shut down, et le DHCP lease time is a week. So J'ai reached a point où Je ne peux pas get a DHCP lease avec a nouveau VM. I could have released le leases on le test VMs manually had I known, mais J'ai besoin de to release those leases so I can get mon free IPs back. DHCP server is serving certains production servers as well, so Je ne peux pas juste nuke tous le leases et call it a day.
DHCP server OS is Ubuntu 12.04.4. Using dhcpd for le DHCP server.
Comment libérer manuellement un bail DHCP sur le serveur DHCP lui-même ?

Apparently there is no such elegant method to accomplish le job.
So, let's do it manually.
- Stop dhcp server.
- Check votre `/var/lib/dhcp/dhcpd.leases` file et check for le entry. It contains le list of tous dhcp leases.
- Supprimez le entry carefully et démarrez le dhcp server again.
