CALIDNS(1) PowerDNS Recursor CALIDNS(1)

NAME

calidns -

calidns - A DNS recursor testing tool

SYNOPSIS

calidns [OPTIONS] QUERY_FILE DESTINATION INITIAL_QPS HITRATE

DESCRIPTION

calidns reads queries from QUERY_FILE and sends them as a recursive query to DESTINATION (an IPv4 or IPv6 address, optionally with a port number), starting at INITIAL_QPS queries per second and aims to have a cache hitrate of HITRATE percent.

It will then try to determine the maximum amount of queries per second the recursor can handle with the aforementioned HITRATE.

QUERY_FILE FORMAT

The format of the QUERY_FILE is very simple, it should contain "QNAME QTYPE" tuples, one per line. For example: 

powerdns.com A
powerdns.com AAAA
google.com A


This is similar to Alexa top 1 million list.

OPTIONS

--increment <NUM>
On every subsequent run, multiply the number of queries per second by NUM. By default, this is 1.1.
--want-recursion
Set this flag to send queries with the Recursion Desired flag set.
