This is the home page for the dhcp_probe software distribution.
dchp_probe attempts to discover DHCP and BootP servers on a directly-attached Ethernet network. A network administrator can use this tool to locate unauthorized DHCP and BootP servers.
Presently the product builds and runs on Solaris 9 on SPARC with gcc. To use it on other platforms, you'll likely need to port it. It makes use of libpcap and libnet.
