[Bug 998712] Re: dnsmasq integration into name resolution broken

[Wolf Rogner]

The /etc/resolv.conf held just a reference to 127.0.0.1

# 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
search rsb.intern rsb.at

I copied a working version over it:

# 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 10.1.0.4
nameserver 10.1.0.254
nameserver 195.202.128.3
search rsb.intern rsb.at

That way, name resolution worked immediately.
This brings back the old and stable name resolution. As far as I can observe this, no side effects as you discussed in #1003842


So far I have disabled dnsmasq in /etc/NetworkManager/NetworkManager.conf


Currently my view is that dnsmasq has some serious issues:

- name resolution in mixed DNS setups
- handling of refreshes of network manager (happens periodically with calls to resolvconf, aperiodically when new SSIDs emerge, network media changes or the machine is put into sleep mode)
- VPN management (which requires several different domains to be intersected)
- caching of resolved names
- handling of /etc/hosts

Hope this helps.
