Thanks, Simon. I found your commit at http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2020q1/013693.html ( http://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=commit;h=ab53883c94f94958e22077c79ba1dae1850a475e ) and patched 2.80 with it. It appears to work, but I noticed two problems:
The first: I have two files in confdir: 10-stubby.conf and 20-nextdns.conf # cat /var/dnsmasq.d/10-stubby.conf server=127.0.0.1#5453 strict-order no-resolv # cat /var/dnsmasq.d/20-nextdns.conf server=127.0.0.1#5342 strict-order no-resolv After restart dnsmasq , the log shows: Sat Feb 29 10:50:44 2020 daemon.info dnsmasq[17671]: using nameserver 127.0.0.1#5342 Sat Feb 29 10:50:44 2020 daemon.info dnsmasq[17671]: using nameserver 127.0.0.1#5453 The order appears to be reversed. The 127.0.0.1#5342 is being used even though it is added by the 20-nextdns.conf ( which should be loaded after 10-stubby.conf) The second problem is: If I delete /var/dnsmasq.d/20-nextdns.conf and send a HUP signal, dnsmasq does not notice that file was deleted and keep using 127.0.0.1#5342. If I restart ( instead of reload/HUP) it will work as expected. If i send a USR1 signal ( after deletion ) I still see: Sat Feb 29 10:56:19 2020 daemon.info dnsmasq[17671]: server 127.0.0.1#5342: queries sent 67, retried or failed 0 Sat Feb 29 10:56:19 2020 daemon.info dnsmasq[17671]: server 127.0.0.1#5453: queries sent 0, retried or failed 0 Atenciosamente/Kind regards, Salatiel On Tue, Feb 11, 2020 at 7:51 AM Simon Kelley <si...@thekelleys.org.uk> wrote: > > In all the released versions of dnsmasq, the order in which the files in > a conf-dir are loaded is indeterminate. > > The next dnsmasq release changes this to alphabetic order. > > > Simon. > > > On 11/02/2020 00:44, Salatiel Filho wrote: > > I am trying to understand the behaviour of conf-dir parameter. > > Although I am running dnsmasq inside openwrt, this is more a dnsmasq > > question than openwrt question. > > > > I have conf-dir=/tmp/dnsmasq.d > > This directory CAN contain files or not.
