4f6716dc | 1 | This is the Unix port of OpenBSD's excellent OpenSSH. |
8efc0c15 | 2 | |
97784962 | 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. | |
8efc0c15 | 6 | |
4f6716dc | 7 | This port consists of the re-introduction of autoconf support, PAM |
8 | support (for Linux and Solaris), EGD[1] support, and replacements for | |
9 | OpenBSD library functions that are (regrettably) absent from most | |
10 | other unices. The only well tested platform currently is Linux, though | |
11 | some Solaris support is beginning to filter in. This version actively | |
12 | tracks changes in the OpenBSD CVS repository. | |
8efc0c15 | 13 | |
97784962 | 14 | The PAM support is now more functional than the popular packages of |
15 | commercial ssh-1.2.x. It checks "account" and "session" modules for | |
16 | all logins, not just when using password authentication. This code is | |
aa51e7cc | 17 | very new and needs further testing. |
8efc0c15 | 18 | |
97784962 | 19 | All new code is released under a XFree style license, which is very |
aa51e7cc | 20 | liberal. Please refer to the source files for details. The code in |
21 | strlcpy.c and mktemp.c is from the OpenBSD project and has its own | |
22 | license (again, see source file for details). | |

4f6716dc | 24 | OpenSSH depends on Zlib[2], OpenSSL[3] and optionally PAM[4]. To build |
25 | the GNOME[5] passphrase requestor (--with-gnome-askpass), you will | |
26 | need the GNOME libraries installed. If you are building OpenSSH on a | |
27 | Unix which lacks a kernel random number pool (/dev/random), you will | |
28 | need to install EGD[1]. | |
aa51e7cc | 29 | |
30 | To build OpenSSH, use the configure script provided. For example: | |
31 | ||
32 | ./configure --prefix=/opt/openssh | |
33 | make | |
34 | make install | |
35 | ||
36 | Will install the OpenSSH binaries in /opt/openssh/bin, the | |
37 | configuration files in /opt/openssh/etc, and so forth. | |

97784962 | 55 | This version of SSH is based upon code retrieved from the OpenBSD CVS |
4f080ebe | 56 | repository on 1999-11-09 which in turn was based on the last free |
57 | version of SSH released by Tatu Ylonen. | |
