flail
The flail package provides a command-line DNS server stress testing tool.
The tool is a paper-thin wrapper around the excellent DNSJava
library.
Features
- Command line tool for executing large numbers of requests against a DNS server.
- ISC license.
Usage
Place a list of hostnames, one per line, in a file called names.txt.
$ cat names.txt
debian.org
example.com
freebsd.org
www.debian.org
www.example.com
www.freebsd.org
Assuming the DNS server under test is at dns.example.com on port 53:
java -jar flail.jar names.txt dns.example.com 53
The program will make random requests for A records for all the names
in names.txt as quickly as possible. The program will produce lines such
as:
17:22:52.483 [main] INFO com.io7m.flail.FlailMain -- requests: 280/280/0 (total/successes/failures)
17:22:52.544 [main] INFO com.io7m.flail.FlailMain -- requests: 290/290/0 (total/successes/failures)
17:22:52.604 [main] INFO com.io7m.flail.FlailMain -- requests: 300/300/0 (total/successes/failures)

17:22:52.724 [main] INFO com.io7m.flail.FlailMain -- requests: 320/320/0 (total/successes/failures)
17:22:52.784 [main] INFO com.io7m.flail.FlailMain -- requests: 330/330/0 (total/successes/failures)
17:22:52.844 [main] INFO com.io7m.flail.FlailMain -- requests: 340/340/0 (total/successes/failures)
17:22:52.905 [main] INFO com.io7m.flail.FlailMain -- requests: 350/350/0 (total/successes/failures)
The program will run indefinitely until it is interrupted.
