[Dnsmasq-discuss] dnsmasq + Cloudflare's DoH service + netflix = stalled

2018-04-16 Thread Dominik
Dear dnsmasq enthusiasts, we encountered a rather strange issue with dnsmasq, the new Cloudflare DNS over HTTPS service (https://bendews.com/posts/implement-dns-over-https/) and Netflix (only in this combination). Once Netflix is started, it queries ichnaea.netflix.com. This query gets answered b

I still can't reproduce this, but tracing through the code, I found two different problems which might have a bearing. I just pushed the fixes to these to git, and tagged 2.80test1 The fixes (top two at http://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=summary) should apply to 2.76, if that's the e

2018-04-16 Thread Simon Kelley
When you're running under the debugger, are you starting dnsmasq with the -d flag? If so, then I'd expect it to stop serving any other requests whilst it's blocked doing TCP stuff. Normally, dnsmasq spawns a new process for each TCP connection, but that is suppressed by the -d flag, to make debuggi

[Dnsmasq-discuss] Router Advertisement: Prefix-Specific Options?

2018-04-16 Thread Luis Marsano
Hi, Apologies if this was answered before. In router advertisements, is there a way to declare one prefix deprecated without deprecating the others? Here’s my situation. I’ve been using the dnsmasq option dhcp-range=set:lan,::,constructor:br-lan,ra-stateless,ra-names,12h to announce a

[Dnsmasq-discuss] DNS auto-update from DHCP hostname?

2018-04-16 Thread Mark Lehrer
Does dnsmasq have the ability to automatically add DHCP clients to DNS based on the client-supplied host name? I see there is a dyndns type of script in contrib, but it would be easier to have the dhcp part of dnsmasq do it if possible. Thanks ___ Dnsm

Hey Simon, I hope you have also seen my other mail (providing some more details about the TCP issue). It' actually likely that the debugger test was with "-d" to prevent dnsmasq from forking. Would running it with "-k" be better in the debugger? The main concern is that dnsmasq even hangs when in

Hi Mark, Idk if this will be of help to you, but LXC has some options to configure this. Here is an example: cat /etc/resolv.conf (I use systemd-resolve but for this example I've commented out my systemd nameserver, I've added in the IP address of the LXC lxcbr0 bridge, and I've added "lxc" as t
