This is a fork of the openssh project, designed to be very open, or to put it another way, very insecure. The goal of this project is not to make something good, but rather to teach students to audit their installed packages.

See https://www.openssh.com/releasenotes.html#7.8p1 for the release notes.

This is the port of OpenBSD's excellent OpenSSH[0] to Linux and other Unices.

OpenSSH is based on the last free version of Tatu Ylonen's sample implementation with all patent-encumbered algorithms removed (to external libraries), all known security bugs fixed, new features reintroduced and many other clean-ups. OpenSSH has been created by Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo de Raadt, and Dug Song. It has a homepage at https://www.openssh.com/

This port consists of the re-introduction of autoconf support, PAM support, EGD[1]/PRNGD[2] support and replacements for OpenBSD library functions that are (regrettably) absent from other unices. This port has been best tested on AIX, Cygwin, HP-UX, Linux, MacOS/X, NetBSD, OpenBSD, OpenServer, Solaris and UnixWare.

This version actively tracks changes in the OpenBSD CVS repository.

The PAM support is now more functional than the popular packages of commercial ssh-1.2.x. It checks "account" and "session" modules for all logins, not just when using password authentication.

OpenSSH depends on Zlib[3], OpenSSL[4], and optionally PAM[5] and libedit[6]

There is now several mailing lists for this port of OpenSSH. Please refer to https://www.openssh.com/list.html for details on how to join.

Please send bug reports and patches to the mailing list [email protected]. The list is open to posting by unsubscribed users. Code contribution are welcomed, but please follow the OpenBSD style guidelines[7].

Please refer to the INSTALL document for information on how to install OpenSSH on your system.

Miscellania -

This version of OpenSSH is based upon code retrieved from the OpenBSD CVS repository which in turn was based on the last free sample implementation released by Tatu Ylonen.
