Hi,
I am using powerdns recursor 4.8.2 and the lua version is Lua 5.1.4
Am trying to achieve the function to block a list of domains via the below lua
script and then redirect the request to a local block page
-- Define new Domain Set
blocked_domains=newDS()
-- Load Domain Set from the file. Format of the file is: 'return {"a.com",
"b.com", "a.fb.com"}'
blocked_domains:add(dofile("/etc/pdns-recursor/full_list_13-11-2019.lua"))
-- blocked_domains:add(dofile("/etc/pdns-recursor/blocked_domains.txt"))
-- define a preresolve() function which gets called by PowerDNS to determine
what to do with a domain
function preresolve(dq)
-- If we see that a query name is not part of one of the blocked domains,
-- or the query is not for an IP(v6) address, we return false and the
normal resolution process continues.
if(not blocked_domains:check(dq.qname) or (dq.qtype ~= pdns.A and
dq.qtype ~= pdns.AAAA)) then
return false
else
dq:addAnswer(pdns.A, "192.168.8.48")
return true
end
end
The thing is that this script only blocks and redirect the user if the site is
an http domain, if its a https domain no block page is displayed though the
site does not open
how do i improve the script so that the domain is blocked and redirected to the
block page even if its a https site, some where on the internet it refered to
set the code to nxdomain and then redirect the request to the block page but i
cant get the code right, some help will be much appreciated.
also currently I have redirected the block page to the IP "192.168.8.48" can i
also get the code to redirect to a domain name instead of an IP address?
Thanks you
Regards,
Clifford Dsouza
