The ARP scanner

• Installation
• Documentation

arp-scan uses the standard GNU automake and autoconf tools, so the typical installation process is:

• Run git clone https://github.com/royhills/arp-scan.git to obtain the latest project source code
• Run cd arp-scan to enter the source directory
• Run autoreconf --install to generate a viable ./configure file
• Run ./configure to generate a makefile for your system
• Run make to build the project
• Optionally run make check to verify that everything works as expected
• Run make install to install (you'll need to be root or use sudo/doas for this part)

You will need GNU automake and autoconf, the make utility, an ANSI C compiler (for example gcc or clang), the development header files and libraries, and libpcap version 1.5 or later.

If you want to run the Perl scripts arp-fingerprint, get-oui and get-iab, you will need to have the Perl interpreter installed. In addition, for get-oui and get-iab, you will need the LWP::UserAgent Perl module.

You can pass various options to "configure" to control the build and installation process. See the file INSTALL for more details.

arp-scan is known to compile and run on the following platforms:

• Linux
• FreeBSD
• OpenBSD
• NetBSD
• DragonflyBSD
• MacOS X
• Solaris 10 (there are known problems with Solaris 11)

All platforms use libpcap (https://www.tcpdump.org/) to send the ARP packets and receive the responses.

The only piece of the code that is implementation-specific is the function to obtain the interface MAC address. This uses Packet Socket on Linux, BPF on BSD and DLPI on Solaris.

The primary source of documentation is the arp-scan wiki at https://www.royhills.co.uk/wiki/
