Projektgeschichte

Roy Hills' upstream changelog records version 1.4 on 2006-06-26 as the first stable public version, after internal versions 1.0 through 1.2 and a 1.3 beta. Early work quickly moved from Linux packet sockets toward portable link-layer support, adding BPF support for BSD and Darwin, Solaris DLPI work, IEEE OUI/IAB update scripts, and packet-generation tests.

The project moved from an internal SVN repository to GitHub in 2013 during the 1.9.2 cycle. That move also changed the development identifiers from increasing SVN revision IDs to Git object hashes and shifted public collaboration toward issues and pull requests.

Later releases kept the old-school Unix toolchain shape, using autoconf/automake, libpcap, manual pages, and text data files, while modernizing around security and portability. The 1.10.0 release added Linux POSIX.1e capability support, flexible output formatting, JSON/XML-format examples, and a consolidated IEEE registry file.

Adoptionsgeschichte

The README explicitly says many distributions provide binary packages and that BSD users may install from ports. The supplied facts show broad package-manager coverage across apk, Homebrew, Debian, Fedora/dnf, MacPorts, Nix, pacman, Ubuntu, and zypper, which matches its role as the canonical packaged ARP LAN scanner.

arp-scan became a package-manager staple because it solves a common administrator problem without requiring IP-layer cooperation: discovering hosts on the local Ethernet segment and mapping MAC prefixes to vendors. It is small enough for scripts, but detailed enough for security inventories, lab networks, appliance discovery, and duplicate-address investigations.

Wie es verwendet wird

The core invocation sends ARP requests on a local link and prints responding IP/MAC/vendor rows. The README points users to `arp-scan --help` and the manual pages for `arp-scan(1)`, `arp-fingerprint(1)`, `get-oui(1)`, and `mac-vendor(5)`.

Packaging details matter because the executable needs raw-packet privileges. Upstream's packager notes ask Linux builders to enable libcap support when possible; `make install` can install `arp-scan` with `CAP_NET_RAW` or fall back to setuid root.

The tool's vendor lookup depends on local IEEE registry-derived files. Upstream has repeatedly updated its OUI/IAB handling as IEEE changed registry formats and URLs, and 1.10.0 moved `mac-vendor.txt` into the system configuration directory so local changes can survive upgrades.

Warum Paket-Nerds sich dafür interessieren

arp-scan is the baseline package against which newer ARP scanners are compared. It is also a neat example of why network tools need package metadata beyond a homepage: raw socket privileges, capability installation, bundled data files, manual pages, and helper scripts all affect the package experience.

The name collision with arp-scan-rs is important: both may install an `arp-scan` command, but their upstreams, licenses, implementation languages, option sets, and release histories are distinct.
