[Dnsmasq-discuss] Update dnsmasq.leases after lease removed using dhcp_release utility?

[Drew Polhamus]

Simon,
  Thank you for the quick reply and sorry for not being clear.

  The problem is the former.  The client attempts to renew the lease and it _doesn't_ reappear in the leases file.  The desired result is that it _would_ reappear.

  I toggled the --dhcp-authoritative flag and that appears to give me the desired functionality and is safe for our configuration. Thank you for the help!

I'm not clear on what's happening, and what you want to happen. Is the problem that the client attempts to renew the lease and it _doesn't_ reappear, or that the client renews the lease and it does re-appear?

I think that either of these behaviours is available, controlled by the --dhcp-authoritative flag.

Cheers,

Simon.
