Description Gary Kotton 2012-12-24 13:42:14 UTC

Description of problem:
A DHCP agent wil create a tap device and run a dnsmasq process for each subnet that is configured on a network. This may exhaust the entire system.

The DHCP agent should limit the networks that are treated by a specific agent.
