| | 1 | This is a Linux port of OpenBSD's excellent OpenSSH. |
| | 2 | |
| | 3 | OpenSSH is based on the last free version of Tatu Ylonen's SSH with |
| | 4 | all patent-encumbered algorithms removed, all known security bugs |
| | 5 | fixed, new features reintroduced and many other clean-ups. |
| | 6 | |
| | 7 | This Linux port basically consists of a few fixes to deal with |
| | 8 | the way that OpenSSL is usually installed on Linux systems, a few |
| | 9 | replacements for OpenBSD library functions and the introduction of PAM |
| | 10 | support. This version tracks changes made to the OpenBSD CVS version. |
| | 11 | |
| | 12 | The PAM support is now more functional than the popular packages of |
| | 13 | commercial ssh-1.2.x. It checks "account" and "session" modules for |
| | 14 | all logins, not just when using password authentication. This code is |
| | 15 | very new and needs further testing. |
| | 16 | |
| | 17 | All new code is released under a XFree style license, which is very |
| | 18 | liberal. Please refer to the source files for details. The code in |
| | 19 | strlcpy.c and mktemp.c is from the OpenBSD project and has its own |
| | 20 | license (again, see source file for details). |
| | 21 | |
| | 22 | OpenSSH depends on Zlib[1], OpenSSL[2] and optionally PAM[3]. To build |
| | 23 | the GNOME[1] passphrase requestor (--with-gnome-askpass), you will |
| | 24 | need the GNOME libraries installed. |
| | 25 | |
| | 26 | To build OpenSSH, use the configure script provided. For example: |
| | 27 | |
| | 28 | ./configure --prefix=/opt/openssh |
| | 29 | make |
| | 30 | make install |
| | 31 | |
| | 32 | Will install the OpenSSH binaries in /opt/openssh/bin, the |
| | 33 | configuration files in /opt/openssh/etc, and so forth. |

| | 50 | This version of SSH is based upon code retrieved from the OpenBSD CVS |
| | 51 | repository on 1999-11-09 which in turn was based on the last free |
| | 52 | version of SSH released by Tatu Ylonen. |
