[WLANware] Domain

[Peter Abrahamsen]

Hi all,

Sorry, somehow I missed seeing the responses to my original message.

My problem is this: with dnsmasq, setting a domain in System ->  
Domain prevents queries for that domain from being passed to my  
upstream DNS server. Which, if you ask me, is counter-intuitive.

I believe the problem is that the configuration of dnsmasq (which is  
installed by default on Freifunk) assumes that anything not local is  
"not us". In short, the border of the "internal domain" is, in the  
common case of a wireless mesh network, not at the Freifunk  
installation, but further upstream. The present Freifunk dnsmasq  
configuration prevents lan hosts from considering themselves to be  
part of an upstream DNS domain.

I can fix this behaviour by commenting out the local=/.domain.net/  
option in dnsmasq.conf. This line is set by (/rom)/etc/init.d/ 
S50dnsmasq:

         test -n "$WAN_DOMAIN" && WAN_DOMAIN_LOCAL="local=/. 
$WAN_DOMAIN/"

Apparently, local addresses can still be looked up by *.lan (and for  
some of us, *.local).

Cheers,
Peter
