NAME

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

−−ecs <SUBNET>

Add EDNS Client Subnet option to outgoing queries using random addresses from the specified SUBNET range (IPv4 only).

−−ecs−from−file

Read IP or subnet values from the query file and add them as EDNS Client Subnet option to outgoing queries.

−−increment <NUM>

On every subsequent run, multiply the number of queries per second by NUM. By default, this is 1.1.

−−maximum−qps <NUM>

Stop incrementing once this rate has been reached, to provide a stable load.

−−minimum−success−rate <NUM>

Stop the test as soon as the success rate drops below this value, in percent.

−−plot−file <FILE>

Write results to the specified file.

−−quiet

Whether to run quietly, outputting only the maximum QPS reached. This option is mostly useful when used with −−minimum−success−rate.

−−want−recursion

Set this flag to send queries with the Recursion Desired flag set.
