-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 In this context, ra and dhcpv6 are equivalent, ra if provided as a part of the dhcp service, and the access controls (no-dhcp-interface) operate on both. Hence RA is configured with a dhcp-range. This is a possible documentation problem, but it's

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Dnsmasq checks for incoming network packets and signals in the same event loop, so the maximum delay to DHCP packets will be the time to read a configuration file once, even if you send 1 SIGUSER1 signals, because the code will interleave

Hello Simon, thanks for your reply. Obviously the problems have gone two days later without having done something. Maybe the lease times where too long and I was too impatient. I reduced the lease times to only a few minutes but later I will set them to some more practical values again. But

Hi Simon, i'm the one of the users Michael Tremer told of (Segmetation faults on IPFire). I followed your hint and activated --log-queries, so we will (may be) see what the problem is. Lucky me, the last few days dnsmasq runs for a couple of hours, the last crash were last night at 04:03AM.

Hi, We have a cloud environment which uses DNSMASQ as DHCP/DNS server; in the cloud, it usually starts lots of VMs concurrently, for example, 1 VM; for each VM, we will configure a static DHCP entry in DNSMASQ configuration and send SIGUSER1 to reload. we observe DNSMASQ becomes very busy of
