The problem is that it doesn't remove it if the network connection is no longer present. This results in an /etc/hosts that looks like : x.x.x.xmachinename # Added by NetworkManager 127.0.0.1 localhost.localdomain localhost ::1machinename localhost6.localdomain6 localhost6 so that any lookups of machinename go to a non-accessible address. The severity of the problem is that virtually no gnome applications will function (in particular GDM, but also gnome-panel, etc.) without being able to access machinename (which should be 127.0.0.1), thus crippling the machine until /etc/hosts is fixed or the network connection resumes. Version-Release number of selected component (if applicable): NetworkManager-0.8.1-4.git20100817.fc13.i686 How reproducible: Always Steps to Reproduce: 1. Boot system 2. Plug in network wire and get IP address (/etc/hosts should be modified) 3. Unplug network wire (/etc/hosts stays the same) 4. Restart X and notice GDM no longer works Actual results: Lookups to machinename go to unreaching IP address instead of 127.0.0.1, GDM fails to function Expected results: /etc/hosts should be changed to put machinename back to 127.0.0.1 if no network is available Additional info: I ended up chattr +i /etc/hosts to keep it from being modified at all. Why should the local machinename ever point to anything other than 127.0.0.1?

If the laptop boots and you login, NetworkManager gets an IP address for the wireless adapter, changes /etc/hosts. If you then reboot, the change to /etc/hosts remains and GDM will not start since there is no route to 'machinename' which in /etc/hosts points to the Wifi address that is not up yet.

Why in the @#$% does NetworkManager add an entry to /etc/hosts anyway? This is absolutely stupid and ridiculous behaviour. I absolutely DO NOT want or need ANYTHING in the hosts file. We run local DNS, and I just wasted an HOUR of my time screwing around reconfiguring my HTTPD proxy ON ANOTHER MACHINE simply because NetworkManager changed my hosts file on THIS laptop a month ago and added an incorrect entry to /etc/hosts. So I thought it was a proxy problem ON ANOTHER MACHINE. . . Since /etc/hosts was incorrect the laptop was unreachable to itself. At this point I'm ready to just remove NetworkManager from this laptop before something else gets seriously screwed up ON ANOTHER MACHINE. I'd rather have to configure the wireless by hand than have this type of behaviour. There is absolutely no need for ANYTHING in /etc/hosts except localhost.

So the problem is definitely upstream. It looks like you can permanently set the hostname in the NetworkManager conf file. Then it won't change. But how does that help people who rely solely on DHCP for that? (Here come the gasps from all the sysadmins. . .but it's job security;) In our case, for example on my laptop, there are two DNS entries for it on the DHCP server. They are tied to the MAC addresses for eth0 and wlan0, and set the hostname according to the interface. So the hostname is either [HOSTNAME] or [HOSTNAME]-wlan0. We need it to be that way. But then NetworkManager causes problems with /etc/hosts. For now I suppose we must use the hack in comment #1. After reading all the bug reports it is evident that the described behaviour is utterly detested by just about everybody. So why is it there?

[Bug 632896] Re: Leaves unreachable entries in /etc/hosts when stopping network
This has been in maverick-proposed for 100 days, and is verification- failed. I removed the proposed package now, as this doesn't seem to make much progress. Also, Maverick has lived with this bug for over a year, so there's not much point fixing it now IMHO. ** Changed in: network-manager (Ubuntu Maverick) Status: In Progress = Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/632896 Title: Leaves unreachable entries in /etc/hosts when stopping network -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Verification probably succeeds for this fix but the package in proposed as a whole causes a regression as identified in bug 729091.
