Coyote Linux is a security-focused mini-distribution of Linux designed to function as a network edge firewall. Developed by Vortech Consulting, LLC, Coyote Linux has a long history of providing simple and effective firewall solutions for home and small business networks.

Originally founded in 1999, Coyote Linux began as a floppy-based distribution derived from the Linux Router Project. To enhance usability, version 2 introduced a Windows-based wizard for creating bootable floppies. At the time, consumer internet routers were not yet widely available, making network sharing a complex task.

The project’s name, "Coyote," was inspired by the original developer’s Time Warner Cable "Road Runner" internet connection. In addition to providing a NAT firewall, Coyote Linux also featured an authentication daemon, rrlogind, which allowed Linux-based authentication for Road Runner. Growing community interest led to the addition of PPP, PPPoE, and other internet connection support.

In 2002, Vortech Consulting launched "Wolverine Firewall and VPN Server," a commercial product based on Vortech Embedded Linux. Unlike its floppy-based predecessor, Wolverine installed from a CD-ROM onto IDE storage, offering VPN support and an enhanced web interface.

By 2005, the original Coyote Linux floppy firewall project was discontinued in favor of Coyote Linux 3, built on Wolverine. Released in October 2005, Coyote Linux 3 was made freely available for personal and educational use. Over the next six years, it received only security updates before eventually becoming inactive.

After years of dormancy, development on Coyote Linux resumed in July 2024. The new version, currently in active development, will be based on the Alpine Linux distribution, continuing the legacy of Coyote as a powerful, lightweight firewall solution.
