Damien Miller56825a11999-11-11 10:50:04 +1100[diff] [blame]1This is the Unix port of OpenBSD's excellent OpenSSH.

Damien Miller5ffa6441999-10-30 11:30:35 +1000[diff] [blame]3OpenSSH is based on the last free version of Tatu Ylonen's SSH with
4all patent-encumbered algorithms removed, all known security bugs
5fixed, new features reintroduced and many other clean-ups.

Damien Miller56825a11999-11-11 10:50:04 +1100[diff] [blame]7This port consists of the re-introduction of autoconf support, PAM
8support (for Linux and Solaris), EGD[1] support, and replacements for
9OpenBSD library functions that are (regrettably) absent from most
10other unices. The only well tested platform currently is Linux, though
11some Solaris support is beginning to filter in. This version actively
12tracks changes in the OpenBSD CVS repository.

Damien Miller5ffa6441999-10-30 11:30:35 +1000[diff] [blame]14The PAM support is now more functional than the popular packages of
15commercial ssh-1.2.x. It checks "account" and "session" modules for
16all logins, not just when using password authentication. This code is
Damien Miller74389c91999-11-09 15:03:01 +1100[diff] [blame]17very new and needs further testing.

Damien Miller5ffa6441999-10-30 11:30:35 +1000[diff] [blame]19All new code is released under a XFree style license, which is very
Damien Miller74389c91999-11-09 15:03:01 +1100[diff] [blame]20liberal. Please refer to the source files for details. The code in
21strlcpy.c and mktemp.c is from the OpenBSD project and has its own
22license (again, see source file for details).

Damien Miller56825a11999-11-11 10:50:04 +1100[diff] [blame]24OpenSSH depends on Zlib[2], OpenSSL[3] and optionally PAM[4]. To build
25the GNOME[5] passphrase requestor (--with-gnome-askpass), you will
26need the GNOME libraries installed. If you are building OpenSSH on a
27Unix which lacks a kernel random number pool (/dev/random), you will
28need to install EGD[1].
Damien Miller74389c91999-11-09 15:03:01 +1100[diff] [blame]29
30To build OpenSSH, use the configure script provided. For example:
31
32./configure --prefix=/opt/openssh
33make
34make install
35
36Will install the OpenSSH binaries in /opt/openssh/bin, the
37configuration files in /opt/openssh/etc, and so forth.
