dnsbulktest contains Power DNS source code.
In short, dnsbulktest sends out many parallel queries to validate resolver performance.
Please see how to build dnsbulktest
Here is how to generate DNS queries with dnsbulktest.
# dnsbulktest --help
Usage: dnsbulktest [--options] ip-address portnumber [limit]
Allowed options:
-h [ --help ] produce help message
-q [ --quiet ] be quiet about individual queries
-t [ --type ] arg (=A) What type to query for
-e [ --envoutput ] write report in shell environment format
|
prepare a queries list file like this:
# cat query_list.txt
1,www.google.com
2,www.amazon.com
3,www.facebook.com
4,www.yahoo.com
5,www.isc.org
|
generate DNS queries
# dnsbulktest 192.168.104.1 53 -t A < query_list.txt

# tshark -i virbr8 port 53 -R '(ip.src == 192.168.104.159)'
tshark: Lua: Error during loading:
[string "/usr/share/wireshark/init.lua"]:46: dofile has been disabled due to running Wireshark as superuser. See http://wiki.wireshark.org/CaptureSetup/CapturePrivileges for help in running Wireshark as an unprivileged user.
tshark: -R without -2 is deprecated. For single-pass filtering use -Y.
Running as user "root" and group "root". This could be dangerous.
