Adblock ignores dnsmasq instance

[Joe_D]

I setup two running dnsmasq instances, one running on port 53 - the other runs on port 5553

The processes are running:

31286 dnsmasq   1436 S    /usr/sbin/dnsmasq -C /var/etc/dnsmasq.conf.dns_lan -k -x /var/run/dnsmasq/dnsmasq.dns_lan.pid
31287 dnsmasq   1428 S    /usr/sbin/dnsmasq -C /var/etc/dnsmasq.conf.dns_adblock -k -x /var/run/dnsmasq/dnsmasq.dns_adblock.pid

And listening:

udp        0      0 100::1:53               :::*
udp        0      0 100::1:5553             :::*

The dhcp/dnsmasq config:

config dnsmasq 'dns_lan'
        option domainneeded '1'
        option localise_queries '1'
        option rebind_protection '1'
        option rebind_localhost '1'
        option local '/lan/'
        option domain 'lan'
        option expandhosts '1'
        option authoritative '1'
        option readethers '1'
        option leasefile '/tmp/dhcp.leases'
        option resolvfile '/tmp/resolv.conf.d/resolv.conf.auto'
        option localservice '1'
        option ednspacket_max '1232'
        option confdir '/tmp/dnsmasq.d'
        list interface 'lan'
        list interface 'vpn'
        option nonegcache '1'
        option logdhcp '0'
        option quietdhcp '1'

config dnsmasq 'dns_adblock'
        option domainneeded '1'
        option localise_queries '1'
        option rebind_protection '1'
        option rebind_localhost '1'
        option local '/lan/'
        option domain 'lan'
        option expandhosts '1'
        option authoritative '1'
        option readethers '1'
        option nonwildcard '1'
        option resolvfile '/tmp/resolv.conf.d/resolv.conf.auto'
        list interface 'lan'
        list interface 'vpn'
        list notinterface 'loopback'
        option localservice '0'
        option port '5553'
        option confdir '/tmp/dnsmasq.d'

I enabled Adblock to use "the second instance" whatever this should be?? I only have named instances

The adblock config:

config adblock 'global'
        option adb_debug '0'
        option adb_safesearch '0'
        option adb_dnsfilereset '0'
        option adb_mail '0'
        option adb_backup '1'
        option adb_maxqueue '4'
        option adb_fetchutil 'uclient-fetch'
        option adb_trigger 'lan'
        option adb_report '1'
        option adb_represolve '1'
        option adb_repiface 'br-lan'
        list adb_sources 'adaway'
        list adb_sources 'adguard'
        list adb_sources 'disconnect'
        list adb_sources 'reg_de'
        list adb_sources 'winspy'
        option adb_dns 'dnsmasq'
        option adb_forcedns '0'
        list adb_zonelist 'lan'
        list adb_portlist '5553'
        option adb_replisten '5553'
        option adb_dnsinstance '1'
        option adb_enabled '1'

The result:

Querying dns on port 5553:

root@OpenWrt:/etc/config# host -p 5553 ad.doubleclick.net openwrt.lan
Using domain server:
Name: openwrt.lan
Address: 100::1#5553
Aliases:

Host ad.doubleclick.net not found: 3(NXDOMAIN)

Yezzz! Adblocks active!

Querying dns on port 53:

root@OpenWrt:/etc/config# host -p 53 ad.doubleclick.net openwrt.lan
Using domain server:
Name: openwrt.lan
Address: 100::1#53
Aliases:

Host ad.doubleclick.net not found: 3(NXDOMAIN)

What? Why? Why is adblock now active for every instance??? I ended in deactivating adblock completely

How can i tell adblock to use my instance on port 5553?

[frollic]

Not using AdBlock, and not in front of any openwrt device right now, but check what files it uses on OS level.

I can imagine both instances read the same file.

@frollic

I can imagine both instances reads the same file.

Yes it is. All the settings in the interface make you believe that a change will cause a change. But selecting the dnsmasq instance just doesn't seem to do anything!

I tried to get rid of

@Joe_D

option confdir '/tmp/dnsmasq.d'

in the instance of 'dns_lan' and removed it, but i made the bill without the landlord...

Stopped dnsmasq, deleted config files in /tmp/etc/dnsmasq.conf.* and restarted dnsmasq... and what do i see?

root@OpenWrt:/tmp/etc# cat dnsmasq.conf.dns_lan | grep conf
# auto-generated config file from /etc/config/dhcp
conf-file=/etc/dnsmasq.conf
resolv-file=/tmp/resolv.conf.d/resolv.conf.auto
conf-dir=/tmp/dnsmasq.d
conf-file=/usr/share/dnsmasq/dhcpbogushostname.conf
conf-file=/usr/share/dnsmasq/rfc6761.conf

This is incredibly annoying!

[Joe_D]

So i added the following option in /etc/config/adblock

 option adb_dnsdir '/tmp/adblock.d'

And after restart of adblock? dnsmasq? (i made many things at the same time!) the following line appeared in /etc/config/dhcp

 option confdir '/tmp/adblock.d'

So i checked again:

root@OpenWrt:/tmp# host -p 5553 ad.doubleclick.net openwrt.lan
Using domain server:
Name: openwrt.lan
Address: 100::1#5553
Aliases:

Host ad.doubleclick.net not found: 3(NXDOMAIN)
root@OpenWrt:/tmp# host -p 53 ad.doubleclick.net openwrt.lan
Using domain server:
Name: openwrt.lan
Address: 100::1#53
Aliases:

ad.doubleclick.net has address 216.58.206.38
root@OpenWrt:/tmp#

Now it works!!!
