## プロジェクトの歴史と使われ方

synscan is a small security CLI: an asynchronous half-open TCP port scanner packaged by Homebrew for users who want a fast SYN-scan tool outside larger scanner suites.

### プロジェクトの歴史

The official digit-labs page describes Synscan as an asynchronous half-open TCP port scanner that sends TCP packets with the SYN flag to blocks of destination addresses as fast as the host interface and kernel can support.

The same page records a compact lineage: Synscan versions up to 3.9b6 were based on version 1.6 by psychoid/tCl, while Synscan 5.0 was a complete rewrite with a cleaner codebase, efficiency improvements, checksum fixes, adjustable scan timing, and a simpler design intended to allow future IPv6 support.

### 採用の歴史

The input package facts show Homebrew packaging for `synscan`. Upstream also lists releases as tarballs and says the tool was known to compile on Linux, xBSD, Mac OS X, and Solaris, which explains why a portable Unix package manager would carry it.

### 使われ方

synscan is used from the command line to perform half-open TCP port scans against ranges of destination addresses. Its companion executable `sslog` is also listed in the Homebrew-derived input facts.

The tool sits in the older Unix security-tool tradition: focused source tarballs, direct packet behavior, and terse CLI usage rather than a large service or framework.

### パッケージ好きにとっての重要性

Package nerds care about synscan because it is the kind of sharp, single-purpose network tool that package managers preserve even when its upstream surface is just a small project page and release tarballs.

Its portability notes across Linux, BSD, macOS, and Solaris make it a good example of formula maintenance for low-level networking code.

### タイムライン

- Pre-5.0: Synscan versions through 3.9b6 were based on version 1.6 by psychoid/tCl.
- 5.0: Synscan was rewritten with efficiency, checksum, timing, and design changes.
- 5.02: The digit-labs page lists synscan-5.02.tar.gz as the newest non-beta release.

### Related projects

- The official page points to the earlier bindshell.net synscan page and credits version 1.6 by psychoid/tCl as the base for older releases.
- In package taxonomies, synscan is adjacent to other TCP port scanners and packet-level security utilities.
