PSSH: Open-Source SSH Server

PSSH is an open-source SSH server designed to be simple, small, and secure. It focuses on providing core SSH functionality without unnecessary bells and whistles.

What is PSSH?

PSSH (Portable SSH) is an open-source SSH server program designed to prioritize simplicity, small size, and security. It is developed and maintained by the OpenBSD team to provide a minimal and dependency-free SSH server option.

Unlike more complex SSH servers like OpenSSH, PSSH aims to offer only essential SSH protocol features and functionality in a compact package. This makes PSSH well-suited for embedding into appliances, small systems, and applications where a full OpenSSH install would be overkill.

Some key features of PSSH include:

  • Small memory footprint - uses around 2MB RAM
  • No dependencies outside of a standard C library
  • Supports SSH protocol 2 including port forwarding, X11 forwarding, and SFTP
  • Available for many operating systems and CPU architectures
  • Active upstream development and maintenance

PSSH prioritizes being a simple, auditable codebase focused narrowly on core SSH functionality over supporting every possible SSH extension and edge case. This can make it a good fit for developers and systems administrators interested in SSH without unnecessary complexity.
