B3 dnsmasq ignores DHCP requests since 2.6.0.3 [SOLVED]
Posted: 07 Oct 2016, 05:33
Dear all,
I've been away for a while due to health issues.
I'm absolutely delighted to see that the forum is still alive!
My problem:
Since applying the 2.6.0.3 standard update (viewtopic.php?f=22&t=5851) and apt-get upgrade, B3s dnsmasq seem to have stopped serving DHCP requests. The only way I can get network access from my clients is to enter details manually, ignoring DHCP.
I can see dnsmasq listening on port 53 and 67:
Note that there is IPv6 stuff in there that I have never seen before on my B3.
Thinking that might have been the cause of the problem, I've tried to disable all IPv6, but to no avail.
My NICs all seem to sport a IPv6 address now. Here is ifconfig output.
I have also noticed that DHCP fails for incoming OpenVPN connections.
Please forgive me if I have missed something obvious or have not included relevant information, it's been a long time since...
Many thanks in advance,
Cheeseboy
