dhcp_probe

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.

This software was created by Irwin Tillman of the Network Systems Group ( networking@princeton.edu ) at Princeton University's Office of Information Technology.
