dnsmasq and interfaces&connections are managed by
dnsmasq is supposed to cache dns entries, and use upstream servers configured via DHCP and manually.
Problem is it seems dnsmasq ends up using upstreams configured only via
nm (using DHCP) - can't figure out how to add manually configured fallbacks (or primaries for that matter).
$ cat NetworkManager.conf [main] plugins=ifupdown,keyfile rc-manager=resolvconf # tried also this instead of 'rc-manager': dns=dnsmasq [ifupdown] managed=true $ cat /run/dnsmasq/resolv.conf nameserver ns-via-dhcp-1 nameserver ns-via-dhcp-2 nameserver ns-via-dhcp-3 nameserver ns-via-dhcp-4 nameserver 127.0.0.1 $ cat /run/NetworkManager/resolv.conf (think this isn't used anymore as resolvconf pkg is installed?) # Generated by NetworkManager search internal.company.domain.co.uk nameserver ns-via-dhcp-1 nameserver ns-via-dhcp-2 nameserver ns-via-dhcp-3 # NOTE: the libc resolver may not support more than 3 nameservers. # The nameservers listed below may not be recognized. nameserver ns-via-dhcp-4 $ cat /run/resolvconf/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 220.127.116.11 nameserver 127.0.0.1 search internal.company.domain.co.uk $ cat /etc/resolvconf/resolv.conf.d/head # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 18.104.22.168
/etc/resolv.conf links to
/etc/resolvconf/run/resolv.conf, whose contents are same as of
22.214.171.124 is the custom nameserver I'm trying to add, but seems like
dnsmasq is not using it. Looking up any domain now takes 2 sec every time, indicating nothing is cached.
dnsmasq process w/ params:
/usr/sbin/dnsmasq -x /run/dnsmasq/dnsmasq.pid -u dnsmasq -r /run/dnsmasq/resolv.conf -7 /etc/dnsmasq.d,.dpkg-dist,.dpkg-old,.dpkg-new --local-service --trust-anchor=.,20326,8,2,e06d44b80b8f1d39a95c0b0d7c65d08458e880409bbc683457104237c7f8ec8d
Also tried adding
server=126.96.36.199 to dnsmasq config, but that didn't work either. Any suggestions?
