Title:
DNS stops working after some time
Status in “dnsmasq” package in Ubuntu:
Invalid
Status in “network-manager” package in Ubuntu:
Invalid
Bug description:
Clean install of 12.04 and it works fine. After few hours, DNS
suddenly stops working, no application can resolve domain names. If I
manually put my ISP's nameserver (124.124.5.141) in /etc/resolv.conf
things start working again. Remove it, and again no resolutions.
Something's wrong with nm's dnsmasq I guess.
Here are some things that might be useful-
shaan@shaan-laptop:~$ cat /run/nm-dns-dnsmasq.conf
server=124.124.5.141
server=124.124.5.140
server=124.124.5.136
shaan@shaan-laptop:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.0.1
I use a wirless router to connect to my ISP. Let me know if any other
info is needed.
