 Posted: Mon Aug 06, 2007 8:01 am Post subject: dhcpcd doesn't create/update resolv.conf anymore [SOLVED] |
 |
|
Hi.
I've run dhcpcd manually (dhcpcd -h myhost -t 10 eth0) and I can see /etc/resolv.conf is no longer updated. I've rm'd /etc/resolv.conf* and run the dhcpcd command again, the file is no longer created.
Does anybody have an idea on what's going on/where I should look?
Thank you in advance.

Can you run it again and add the "-d" option? Maybe the debug info will provide a clue.

Empty. But the problem arises even when I'm running dhcpcd manually, so the network configuration file is out of cause.

Woops... I was looking for a -v switch  ...

BTW I have net-misc/dhcpcd-3.0.16-r1. Does it mean someting special? And what is that resolvconf thing?... I have no such process  .

Did you maybe emerge net-dns/resolvconf-gentoo at some point?

That's where I'm investigating at the moment: I've seen dnsmasq, which I'm using with Qemu virtual machines, has a dependency on resolvconf. I now remember I enabled that use flag, thinking I was going to read further but I didn't  as usual ...
I'm currently reading the man pages for that. There is a paragraph about /etc/resolv.conf no longer being updated.
| man resolvconf wrote: | | To make the resolver use the dynamically generated resolver configuration file the administrator should ensure that /etc/resolv.conf is a symbolic link to /etc/resolvconf/run/resolvconf/resolv.conf. This link is never modified by /sbin/resolvconf. If you find that /etc/resolv.conf is not being updated, check to see that the link is intact. |
Sorry for the silly question. File /etc/resolv.conf has to be a symlink to /etc/resolvconf/run/resolvconf/resolv.conf. BTW won't there be a problem with my PPTP client and resolv.conf as this program directly manipulates the resolv.conf file by creating backups and writing its own file?

I don't have any idea. I installed it once, ages ago, and it played a similar game with my resolv.conf. I just ditched it and went back to /etc/resolv.conf. Unless you have a fairly complicated dns setup or need multiple configurations, I'd just get rid of the thing.

Indeed. There is no such directory /etc/resolvconf/run/resolvconf/. I placed the resolv.conf file in /etc/resolvconf/run/ and symlinked /etc/resolv.conf to that file but it didn't help. Note I expect it doesn't since the directory in which I put the file is not the one mentioned in the man pages. I think I'll cope without resolvconf.
Thanks for your help.

I recompiled dnsmasq with -resolvconf, removed resolvconf-gentoo and recompiled dhcpcd. Problem solved  . Thanks again.

Thanks for the resolvconf-gentoo tip - just saved my day.
resolvconf-gentoo... right. vpnc pulls it in. Actually the merge tells about the symlink change so shame on me.
