Bug 406139 – net-dialup/ppp-2.4.5-r2: /etc/resolv.conf gets emptied upon connection re-negotiation

• Status: RESOLVED DUPLICATE of bug 400845
• Product: Gentoo Linux

[Description Martin Mokrejš 2012-02-28 13:06:03 UTC]

I usee pppd for my main connection and this fetches DNS info from a remote DHCP server. The parsed values are stored in /etc/ppp/resolv.conf. Contents of this file get be added by "pppd" to /etc/resolv.conf. My provider forces re-negotiation after about 12hrs or so, which, I think, triggers "pppd" to revert the /etc/resolv.conf into the original state (with just the single comment line in it):

$ cat /etc/resolv.conf
# Generated by resolvconf
$

Then, pppd re-connects in few seconds, effectively gets same DNS info back but, does not append contents of the /etc/ppp/resolv.conf to /etc/resolv.conf. Some script just does not startup again anymore. Probably related to /etc/init.d/net.ppp0 contents because no "/etc/init.d/net.ppp0 restart" was called. Could iflplugd or similar tool be of help here?

I do not have the remove server to test this against anymore, please try to reproduce this yourself.
