OIT Network Switching and Routing


This is the home page for the arpsend software distribution.

arpsend sends an Ethernet frame containing an IP ARP request or reply packet containing fields you specify. This is a diagnostic tool intended for use by network administrators.

Presently the product builds and runs on Solaris 9 and 10 on SPARC with gcc. To use it on other platforms, you'll likely need to port it. It makes use of libnet.

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