Re: (no subject)

Dear Bert;

Firstly, thanks a lot for fast and illustrative replies. i learned a  
lot of things. But i have a problem again :(
I change the dnsdistconf.lua file blockfilter() function as:
function blockFilter(remote, qname, qtype, dh)

      print("any query, tc=1")
      dh:setTC(true)
	 dh:setQR(true)

	 if(qname:isPartOf(block))
	 then
		print("Blocking *.powerdns.org")
		return true
	 end
	 return false
end

then i did re-installation and run dnsdist. However, nothing is changed..
