Okay so I have found the issue pertaining to dns resolution on Ubuntu 16.04.2! There is a critical bug in the package dnsmasq-base here: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1639776 The fix hasn't yet been applied to the current version of dnsmasq-base.
This time I have all the dependencies on 1.2.6 at their newest version and installing the patched .deb version provided by Harald Rudell fixes DNS name resolution on wakeup/suspend and with restart of the network manager, all while cooperating with openvpn. I hope this helps anyone on 16.04.2 LTS! wget https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1639776/+attachment/4780245/+files /dnsmasq-base_2.76-4ubuntu1FIX1639776ubuntu1_amd64.deb sudo dpkg -i dnsmasq-base_2.76-4ubuntu1FIX1639776ubuntu1_amd64.deb This appears to have actually worked, and is much better than using dnscrypt-proxy (which I have found to be incredibly slow) or holding back a bunch of packages. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1636395 Title: dnsmasq not working with OpenVPN Status in dnsmasq package in Ubuntu: Confirmed Status in openvpn-systemd-resolved package in Ubuntu: Confirmed Bug description: I'm using OpenVPN configured with Network Manager. My VPN have a DNS server configured by OpenVPN and config pushed by it while connecting. This server is not registered by dnsmasq so domain names are not resolved but pinging by IP address works. When I test name resolving by pointing to DNS server (172.16.1.1) from VPN provider it's works. For example: $ host google.com 172.16.1.1 Using domain server: Name: 172.16.1.1 Address: 172.16.1.1#53 Aliases: google.com has address 172.217.0.174 google.com has IPv6 address 2607:f8b0:400b:807::200e google.com mail is handled by 30 alt2.aspmx.l.google.com. google.com mail is handled by 20 alt1.aspmx.l.google.com. google.com mail is handled by 40 alt3.aspmx.l.google.com. google.com mail is handled by 10 aspmx.l.google.com. google.com mail is handled by 50 alt4.aspmx.l.google.com. But if I test without pointing DNS server is not working: $ host google.com ;; connection timed out; no servers could be reached My /etc/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 127.0.1.1 To repair this bug I have to kill dnsmasq and it's automatically reloaded.
