[gentoo-user] Something went wrong with DNS, plz help!
The first reboot after recent update of the system have shown that I cannot open any webpage in Firefox. More exactly, Firefox or my system cannot any more resolve URL to IP address (sorry if I use wrong terms). Thus, host gmail.com gives: ;; connection timed out no servers could be reached Nevertheless dig @8.8.8.8 gmail.com reports the corresponding IP adresses. I have not changed any my network settings and my /etc/conf.d/net file still contains list of my DNS servers that contains server 8.8.8.8 as well but somehow it is not enough any more. :( During my last system update, I suddenly found that I had to update about 150 packages, what was a little bit strange as I update my system at least once a week. I have attributed that to the remnants of gnome2 (now I am using fxce4) that I have not cleaned completely and that is now going to update. So, I deviated a bit from my usual system update routine trying to fix that. Nevertheless, as to my view, during my system update I did nothing to distroy the DNS lookup. Luckily, I save my system update logs and now can attach the last one to this e-mail. Please, help me to recover my internet access, as I still have to do a lot of real work till Monday and have not enough time to investigate this problem alone and without a proper internet access. :( # emerge-webrsync Fetching most recent snapshot ...

The computer can't make them up by magic.. You need to create static nameserver entries because you use a static (i.e. no dhcp) configuration. Add them to /etc/resolvconf.conf If it still gets removed across restarts then you have some local modification going on that does deletions you don't know about. You then have too find them and turn them into something you do know about. -- Alan McKinnon alan.mckin...@gmail.com

But I had no chance to check this solution: after booting my Gentoo computer once again, I have found out that now /etc/resolv.conf was created *with* DNS servers IPs, and everything works fine. But it is *very* strange as I have *not* changed anything after my previous reboot. Absolutely. Have I discovered a new Windows-like fix for a Gentoo system that can be called Just reboot it several times?

More exactly, Firefox or my system cannot any more resolve URL to IP address (sorry if I use wrong terms). Thus, host gmail.com http://gmail.com gives: ;; connection timed out no servers could be reached Nevertheless dig @8.8.8.8 http://8.8.8.8 gmail.com http://gmail.com reports the corresponding IP adresses. I have not changed any my network settings and my /etc/conf.d/net file still contains list of my DNS servers that contains server 8.8.8.8 as well but somehow it is not enough any more. :( During my last system update, I suddenly found that I had to update about 150 packages, what was a little bit strange as I update my system at least once a week. I have attributed that to the remnants of gnome2 (now I am using fxce4) that I have not cleaned completely and that is now going to update. So, I deviated a bit from my usual system update routine trying to fix that. Nevertheless, as to my view, during my system update I did nothing to distroy the DNS lookup. Luckily, I save my system update logs and now can attach the last one to this e-mail. Please, help me to recover my internet access, as I still have to do a lot of real work till Monday and have not enough time to investigate this problem alone and without a proper internet access. :( what is the contents of /etc/resolve.conf? # Generated by net-scripts for interface lo domain mynetwork That isn't right. It should say it's for interface eth0. At first I thought eth0 wasn't being brought up, but then you quoted replies from dig, so it must be. After the last reboot I magically have got the right /etc/resolv.conf with DNS servers IPs. Even more strange is that it happened *without* my intervention: just a few reboots (one was no enough!). This, by the way, reminds me MS Windows very much. I am afraid that you will not believe me, but I really did not changed any configuration and have not (re)emerged anything after the previous reboot. Why it did not worked then and does work now? It is really very strange! That is all. I tried to add here lines like: nameserver 8.8.8.8 but found out that this file is rewritten on every reboot. My net try was to create /etc/resolv.conf.tail file and put that line there but that did not help either. Then the problem is obvious - you have no nameserver entries as you don't create any. The computer can't make them up by magic... But it did it just before the last update: it created DNS entries in /etc/resolv.conf from my /etc/conf.d/net file on every reboot. And now it cannot do this magic? You need to create static nameserver entries because you use a static (i.e. no dhcp) configuration. Add them to /etc/resolvconf.conf It does not help as /etc/resolv.conf is overwritten on every reboot. If it still gets removed across restarts Yes, it does. Do you still have netifrc installed? Maybe it got lost in all that updating work. Try emerging it again anyway. As I have already written, DNS resolution now magically works again and without any intervention from my side: just a few reboots (one was no enough!). So, no need to re-emerge netifrc now. Do your 90-network-rules look like mine? $ cat /lib/udev/rules.d/90-network.rules # do not edit this file, it will be overwritten on update # /etc/udev/rules/90-network.rules: triggering network init-scripts # Activate our network if we can SUBSYSTEM==net, ACTION==add,RUN+=net.sh %k start SUBSYSTEM==net, ACTION==remove, RUN+=net.sh %k stop My file is exactly the same, and it was changed on May 10, 2014 last time. So, it could not be the cause. I'm clutching at straws here, and I hear others doing the same ;-( Everything is very, very strange.
