This package was debianized by Philip Hands on 31 Oct 1999 (with help from Dan Brosemer ) It was downloaded from here: ftp://ftp.fu-berlin.de/unix/security/openssh/openssh-2.3.0p1.tar.gz worldwide mirrors are listed here: http://www.openssh.com/ftp.html The Debian specific parts of the package are mostly taken from the original ssh package, which has since been renamed as ssh-nonfree. The Debian patch is distributed under the terms of the GPL, which you can find in /usr/share/common-licenses/GPL. In addition, as a special exception, Matthew Vernon gives permission to link the code of the Debian patch with any version of the OpenSSH code which is distributed under a license identical to that listed in the included Copyright file, and distribute linked combinations including the two. You must obey the GNU General Public License in all respects for all of the code used other than OpenSSH. If you modify this file, you may extend this exception to your version of the file, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version. The upstream source for this package is a combination of the ssh branch that is being maintained by the OpenBSD team (starting from the last version of SSH that was distributed under a free license), and porting work by Damien Miller to get it working on Linux. Other people also contributed to this, and are credited in /usr/share/doc/ssh/README.
