Does it print out anything at all?
Can you show a 'dig' command that shows TC:0 response and no fallback to
TCP/IP?
Thanks!

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..
