The DHCP Traffic can be collected simultaneously from many different devices:
- windows server/workstation
- linux server
- switch mirror port (SPAN) - recommended.
- TAP device
- manual import from a saved network dump (pcap file)

See an example of a report: http://www.compek.net/DHCP_Insight.png

This version is a beta.

nohup tcpdump -nns0 -C10 -W10 port 67 or port 68 -w /opt/tcpdump/dhcp.pcap -z /opt/tcpdump/pcap2txt.sh &>/dev/null &

where /opt/tcpdump/pcap2txt.sh is a script:

/usr/sbin/tcpdump -tttt -ev -nns0 port 67 or port 68 -r $1 > /opt/tcpdump/dhcp.txt
