[Bug 389006] Re: NetworkManager Internet Connection Sharing fails to route DNS
We've obviously failed by not providing further information as to the state of this fix -- and I'm not even sure this ever landed as a Lucid SRU yet -- for that I'm very sorry. I'm also responsible for not getting back to this bug any sooner. Tony, could you please give me the information as to how far you got with getting this SRU ready, and what else needs to be done to upload that to lucid-proposed? There's at least one other fix that could be bundled with this SRU, and it would be very good to have now despite how close we are to Precise being released. Seems to me like it's probably a pretty simple fix in Lucid. I'm marking the floating task as Fix Released because I'm very certain ICS works well in later releases. If not, we can (preferably) file new bugs, or nominate the particular release. ** Changed in: network-manager (Ubuntu) Status: Fix Committed = Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/389006 Title: NetworkManager Internet Connection Sharing fails to route DNS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/389006/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 389006] Re: NetworkManager Internet Connection Sharing fails to route DNS
I was trying to share a connection just by creating an ad hoc connection with network-manager/dnsmasq and NAT but what happens is that dsnmasq, despite being a dhcp and dns server, it's used by network-manager to create the connection, but does not provide the DHCP service, even when I config /etc/dnsmasq.conf to do it. if I run sudo /etc/init.d/dnsmasq status it gives me this output: * Checking DNS forwarder and DHCP server dnsmasq * (not running) So basically, my work around was to install dhcp3-server and configure /etc/dhcp3/dhcpd.conf to make it work with the same IP that network- manager mysteriously (I've been trying to change this, anyone knows where???) chooses to create the connection with 10.42.43.1. -- NetworkManager Internet Connection Sharing fails to route DNS https://bugs.launchpad.net/bugs/389006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 389006] Re: NetworkManager Internet Connection Sharing fails to route DNS
I'm targeting this to Lucid since it effectively breaks connection sharing. I can confirm that sudo killall -s HUP dnsmasq makes it work, so it appears to be a problem with the timing of /etc/resolv.conf when dnsmasq is started. Because dnsmasq is started with the no-poll parameter, it doesn't pick up on changes in resolv.conf all by itself. I would suggest we: * contact NM upstream to ask if no-poll is a deliberate decision, and the rationale * upload NM patched to NOT use no-poll when firing up dnsmasq, to verify that this fixes the issues with DNS and connection sharing -- NetworkManager Internet Connection Sharing fails to route DNS https://bugs.launchpad.net/bugs/389006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 389006] Re: NetworkManager Internet Connection Sharing fails to route DNS
I'm currently working on an update to NM 0.8-rc1, so I took a quick look at the nm-dnsmasq-manager code. Looks like '--no-poll' was removed sometime between the Karmic snapshot of NM ( 0.8~a~git.20091013t193206.679d548 ) and 0.8-rc1, so this *should* be fixed by the upload. As it's in the upstream git tree, I'm going to change this to FixCommitted. When I get a chance, I'll try and find the actual commit that fixed it, and include it in a comment. ** Changed in: network-manager (Ubuntu Lucid) Status: Confirmed = Fix Committed -- NetworkManager Internet Connection Sharing fails to route DNS https://bugs.launchpad.net/bugs/389006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes, the current plan is to release 0.8-rc1 in it's entirety as an SRU for Karmic.

[Bug 389006] Re: NetworkManager Internet Connection Sharing fails to route DNS
I had the same problem. I sent an HUP signal to dnsmasq and it started working. sudo killall -s HUP dnsmasq I hope it works for you too. My diagnosis is that at the time dnsmasq is executed, the /etc/resolv.conf file is empty since the NetworkManager cleans it and the main interface is not ready so it has not been filled yet. dnsmasq is started with --no-poll option. Therefore it cannot load the new /etc/resolv.conf updated by the main interface. Sending HUP forces it to reload and then it works fine.. Dropping the --no-poll option from the Network Manager default should also help but I could not find where it is. -- NetworkManager Internet Connection Sharing fails to route DNS https://bugs.launchpad.net/bugs/389006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 389006] Re: NetworkManager Internet Connection Sharing fails to route DNS
Another confirmation here. It seems that dnsmasq doesn't want to listen on the correct interface. Here's the setup. The Ubuntu machine is connected to my router (192.168.1.1), which is connected to the internet. The Ubuntu box has address 192.168.144 on the side facing the router and internet, and 10.42.43.1 on the side that it is providing NAT to. I ran some DNS lookups on the Ubuntu machine that is doing NAT. The first query is to the router (192.168.1.1), which is connected to the internet. The next three queries are to different interfaces on the the local machine. The only one that DOESN'T work is the interface that I'm actually interested in, which is 10.42.43.1 -- it's the address that the Ubuntu machine tells its clients is the DNS server. # Querying the router OK $ host ubuntu.com 192.168.1.1 Using domain server: Name: 192.168.1.1 Address: 192.168.1.1#53 Aliases: ubuntu.com has address 91.189.94.156 ubuntu.com mail is handled by 10 mx.canonical.com. # Localhost interface OK $ host ubuntu.com 127.0.0.1 Using domain server: Name: 192.168.1.1 Address: 192.168.1.1#53 Aliases: ubuntu.com has address 91.189.94.156 ubuntu.com mail is handled by 10 mx.canonical.com. # Ubuntu machine's router-facing interface OK $ host ubuntu.com 192.168.1.144 Using domain server: Name: 192.168.1.1 Address: 192.168.1.1#53 Aliases: ubuntu.com has address 91.189.94.156 ubuntu.com mail is handled by 10 mx.canonical.com. # The client-side NAT interface of the Ubuntu machine NOT OK $ host ubuntu.com 10.42.43.1 Using domain server: Name: 10.42.43.1 Address: 10.42.43.1#53 Aliases: Host ubuntu.com not found: 5(REFUSED) -- NetworkManager Internet Connection Sharing fails to route DNS https://bugs.launchpad.net/bugs/389006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm this on both a fresh install of Jaunty and on Karmic. In both cases I created an ad-hoc network, which by default enables sharing, but DNS didn't work for clients that connected. ** Changed in: network-manager (Ubuntu) Status: Incomplete = Confirmed -- NetworkManager Internet Connection Sharing fails to route DNS https://bugs.launchpad.net/bugs/389006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 389006] Re: NetworkManager Internet Connection Sharing fails to route DNS
I believe I am experiencing this issue as well. My configuration is as follows: Fresh Jaunty install on my laptop, with wireless interface connected to internet and wired interface connected to LAN. Older Jaunty install (upgraded from ?, probably Feisty) on desktop, wired interface connected to LAN. Laptop is configured via network-manager to share wireless internet to LAN. Both machines can ping each other and connect via SSH, etc. Desktop machine can reach internet sites by IP. However, Desktop machine will not resolve DNS names. Attempting to resolve google.com in nslookup results in the following: google.com Server: 10.42.43.1 Address:10.42.43.1#53 ** server can't find google.com: REFUSED As in the initial report, I have worked around this for now by manually editing resolv.conf on the desktop to match the laptop. As nmap from the desktop shows that port 53 is accessible on the laptop, I believe this is an issue with my dnsmasq configurating, which I haven't dove in to yet. It's odd, as this initially worked, and I haven't changed any configuration. It may have stopped working after post-installation updates on the laptop, I'm not certain about the timing.
