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.
- --ecs <SUBNET>
- Add EDNS Client Subnet option to outgoing queries using random addresses from the specified SUBNET range (IPv4 only).
- 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.
- Whether to run quietly, outputting only the maximum QPS reached. This option is mostly useful when used with --minimum-success-rate.
- Set this flag to send queries with the Recursion Desired flag set.
