This is a Linux port of OpenBSD's excellent OpenSSH. 

OpenSSH is based on the last free version of Tatu Ylonen's SSH with all 
patent-encumbered algorithms removed, all known security bugs fixed, new 
features reintroduced and many other clean-ups.

This Linux port basically consists of a few fixes to deal with the way that
OpenSSL is usually installed on Linux systems, a few replacements for 
OpenBSD library functions and the introduction of partial PAM support.

The PAM support is less than optimal - it is only used when password 
authentication is requested, so things like pam_limits will not apply if a
user authenticates with a RSA key. OTOH this is exactly the level of support
that the popular Linux SSH packages have. Perhaps a PAM hacker can rectify 
this?

All new code is released under a XFree style license, which is very liberal.
This code is released with no warranties of any kind, neither I nor my 
employer (Internet Business Solutions) will take any responsibility for 
any loss, damage or liability arising from the use or abuse of this software.

OpenSSH depends on Zlib, OpenSSL and PAM. Use the Makefile.GNU to build it.

This version of SSH is based upon code retrieved from the OpenBSD CVS
repository on 1999-10-26, which in turn was based on the last free 
version of SSH released by Tatu Ylonen.
