Is the fix released to Xenial or not? I'm having this problem from years
already...

And I'm with Xenial still having the problem.

Also in artful. bug #1639776 is marked as "fixed" which is fake news.

The the other guy above, I often see this after disconnecting from VPN
(Cisco AnyConnect).

My version:
dnsmasq/artful,artful 2.78-1 

I installed dnscrypt-proxy, checked the IP in /etc/dnscrypt-proxy
/dnscrypt-proxy.conf and set the system to use that IP. We'll see if
that helps.

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[pgramond]

Hi, i've the same problem when i disconnect-reconnect a PPP connection (mobile 
broadband actually).
I 've found a workaround killing dnsmasq in pre-up script of Network-Manager 
(then, dnsmasq gets automatically restarted).
The problem appeared passing from network-manager 1.2.2 to 1.2.6 (while dnsmasq 
remained unchanged).

Will Network-Manager be patched, or should we wait for dnsmasq upagrade
in Yakkety ?

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Henrik Nilsson]

I see this bug marked as "fix released" in January and that it should be
fixed 2.76-4.1, however I only see version 2.76-4 even if I in the
"Software & Updates" settings set my "Ubuntu Software" to download from
"Main Server".

$ apt list dnsmasq
Listing... Done
dnsmasq/yakkety,yakkety 2.76-4 all

or am i misunderstanding something?

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Kostadin Stoilov]

I have also been affected by this bug after upgrading network-manager
and related components to 1.2.6-0ubuntu0.16.04.1 from
1.2.2-0ubuntu0.16.04.4

My current workaround is to do:

sudo apt install network-manager=1.2.2-0ubuntu0.16.04.4
sudo apt install libnm-glib-vpn1=1.2.2-0ubuntu0.16.04.4
sudo apt install libnm-glib4=1.2.2-0ubuntu0.16.04.4
sudo apt install libnm0=1.2.2-0ubuntu0.16.04.4
sudo apt install libnm-util2=1.2.2-0ubuntu0.16.04.4

Followed by:
sudo apt-mark hold libnm-glib-vpn1
sudo apt-mark hold libnm-glib4
sudo apt-mark hold libnm0
sudo apt-mark hold network-manager
sudo apt-mark hold libnm-util2

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Ernst Sjöstrand]

The Redhat patch is the same patch as the one that fixes Debian bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=834722

That patch is already upstream, where the debian package seems to be maintained 
also:
http://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=commitdiff;h=0682b7795cd0c25553b91de89c2a3b3d3ff17014;hp=b637d7815da89b5fb04c27b1d9a361fe5b2622a0

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Rocko]

I have noticed that doing a "sudo service network-manager restart"
usually fixes things, but not always and not for everything. For
instance, on my laptop at the moment firefox can't find any webpages
("Server not found"), but Chrome is working fine; ntpd is complaining
twice a minute in the log that it can't find 0.ubuntu.pool.ntp.org etc,
even though "nslookup 0.ubuntu.pool.ntp.org" gives a valid address;
"ping google.com" says "Name or service not known", even though
"nslookup google.com" returns a valid address. "dig google.com" is
working.

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Dominik]

I have the same problem, but only some dns queries stop working. For
instance, google.com works fine, while duckduckgo.com doesn't.

When trying to ping a server that doesn't work, it fails immediately
with the message (translating from Polish, sorry): This name or service
is unknown.

I have seen workarounds like restarting dnsmasq, or disabling it in
/etc/NetworkManager/NetworkManager.conf, but these don't work for me.
What works is doing dpkg-reconfigure resolvconf.

[Michael Gratton]

Some data points about this:

- Name resolution always works fine after first boot
- When name resolution is failing, dnsmasq seems to have stop accepting 
connections on UDP on 120.0.1.1 (TCP seems to work fine)
- I can reproduce the issue connecting to wifi at work - WPA2 enterprise wifi 
network
- I cannot reproduce the issue on the home wifi - WPA2 personal

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Martin Pitt]

OK. This could be because NM does not feed it with correct DNS data, or
dnsmasq itself gets confused after resuming. Assigning to NetworkManager
for now.

My apologies, I should have said "To work around the problem" in the

It looks like it, yes. As I (obliquely) mentioned in comment 3, dnsmasq 
seems to stop responding to UDP requests on 127.0.0.1 after resume.

So are you trying to not use NM's dnsmasq instance because that stops
working after suspend/resume?

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Michael Gratton]

Well I'm posting this from the computer with the problem, so yes I'm
online. :)

To fix the problem I need to manually edit /etc/resolv.conf and replace
dnsmasq's 127.0.0.1 with resolve's 127.0.0.53 (or any other reachable
name server).

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Martin Pitt]

Are you sure that you are actually online? What does "nmcli g" say? Does
"dig A www.ubuntu.com @8.8.8.8" work?

Title:
  Name resolution stops working after resume from suspend

Bug description:
  After upgrading to Yakkety, when my Ubuntu GNOME laptop resumes from
  suspend DNS resolution stops working.

  After resuming, systemd-resolved is running and libnss-resolve is
  installed, but /etc/resolv.conf contains 127.0.1.1 as the the only
  name server. The dnsmasq-base package is installed since it is pulled
  in by both network-manager and lxc1, and both NM and libvirt have
  spawned instances of dnsmasq:

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Michael Gratton]

Name resolution, in everything I tried (ping, Epiphany, Geary).

Is it normal for dnsmasq to not listen on UDP?

[Touch-packages] [Bug 1631241] Re: Name resolution stops working after resume from suspend

[Martin Pitt]

With NetworkManager we switched back to the "dnsmasq" plugin, so it is
indeed correct that resolv.conf only contains 127.0.1.1. It also does
that without suspending.

So what is actually not working?
