#DHCP command-line query and testing tool Automatically exported from code.google.com/p/dhquery
##History I needed some DHCP testing tool for my projects, based on FreeRADIUS dhcp code.
dhcping had no DISCOVER packet handling, it couldn't do stress test and didn't allow changing request parameters.
Also, I needed Nagios testing plugin for DHCP cluster testing.
##Features dhquery can send any common packet type, repeat it several times for stress testing or perform cycle testing: DISCOVER, REQUEST and RELEASE.
Also it can work as a Nagios plugin.
##Requirements Python and pydhcplib
