[Bug 1632681] Re: SonicWall NetExteder broken by new nsswitch.conf configuration

[dikkjo]

the changes i've made previously had other side effects, like breaking Spotify net detection.
At the moment i'm using this: 

hosts: files mdns4_minimal [NOTFOUND=return] resolve dns
[!UNAVAIL=return]

vpn and spotify are working

Title:
  SonicWall NetExteder broken by new nsswitch.conf configuration

Status in systemd package in Ubuntu:
  New

Bug description:
  
  In Ubuntu Yakkety the following line in /etc/nsswitch.conf breaks DNS resolution via the VPN tunnel created by Sonicwall NetExtender application. 

  
  hosts:          files mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns 

  
  Changing this line to:

  hosts:          files mdns4_minimal [NOTFOUND=return] resolve
  [UNAVAIL=return] dns

  or

  hosts:         files mdns4_minimal [NOTFOUND=return] dns
  [!UNAVAIL=return] resolve

  
  I have not found documentation on what "resolve" means, so im not sure this lines makes global sense, but it solve my dns problem. If i have to guess its another systemd incarnation.

  As a side note NetExtender modifies /etc/resolv.conf and adds the VPN
  DNS servers as the first entries. So when NetExtender is connected the
  first lines in /etc/resolv.conf contains the VPN DNS IP and only after
  there is the local dnsmasq entry.

  Sadly i could not found which package creates this file as "dpkg-query
  -S /etc/nsswitch.conf" returns no results on my system.
