In their own words
scanlogd
scanlogd is a free TCP port scan detection tool for Linux and self-hosted deployments. It captures packets through Linux raw sockets, libnids, or libpcap. The project advises against using libpcap alone when fragmented IP packets matter, recommending libnids for non-Linux systems or monitoring an entire network. The official download page lists release 2.2.8, release files and signatures, an Openwall archive, and source browsing through GitHub. scanlogd is listed in Owl, Debian GNU/Linux, Gentoo Linux, ALT Linux, and OpenWrt, with ports in OpenBSD and FreeBSD collections. A contributed precompiled Win32 build is also linked. The project describes scanlogd as designed to be totally safe to use and points readers to its manual page and a Phrack article. Openwall offers commercial configuration, compilation, and installation support at US $250/hour with a six-hour minimum or US $9,000/week; fixed-price quotes are available for sufficiently specific projects.
