6 * On systmes which lack a /dev/random driver, version of this port
7 * prior to 1.2.2 were not correctly seeding OpenSSL's random number
8 * pool. This resulted in lower quality RSA keys being generated. If
9 * you generated host or user keys with v1.2.2 or previous versions,
10 * please generate new ones using a more recent version.
12 This is the port of OpenBSD's excellent OpenSSH to Linux and other
15 OpenSSH is based on the last free version of Tatu Ylonen's SSH with
16 all patent-encumbered algorithms removed (to external libraries), all
17 known security bugs fixed, new features reintroduced and many other
18 clean-ups. More information about SSH itself can be found in the file
19 README.Ylonen. OpenSSH has been created by Aaron Campbell, Bob Beck,
20 Markus Friedl, Niels Provos, Theo de Raadt, and Dug Song. It has a
21 homepage at http://www.openssh.com/
23 This port consists of the re-introduction of autoconf support, PAM
24 support (for Linux and Solaris), EGD[1] support and replacements for
25 OpenBSD library functions that are (regrettably) absent from other
26 unices. This port has been best tested on Linux, Solaris, HPUX, NetBSD
27 and Irix. Support for AIX, SCO, NeXT and other Unices is underway.
28 This version actively tracks changes in the OpenBSD CVS repository.
30 The PAM support is now more functional than the popular packages of
31 commercial ssh-1.2.x. It checks "account" and "session" modules for
32 all logins, not just when using password authentication.
34 OpenSSH depends on Zlib[2], OpenSSL[3] and optionally PAM[4].
36 There is now several mailing lists for this port of OpenSSH. Please
37 refer to http://www.openssh.com/list.html for details on how to join.
39 Please send bug reports and patches to the mailing list
40 openssh-unix-dev@mindrot.org. The list is open to posting by
43 If you are a citizen of the USA or another country which restricts
44 export of cryptographic products, then please refrain from sending
45 crypto-related code or patches to the list. We cannot accept them.
46 Other code contribution are accepted, but please follow the OpenBSD
49 Please refer to the INSTALL document for information on how to install
50 OpenSSH on your system. The UPGRADING document details differences
51 between this port of OpenSSH and F-Secure SSH 1.x.

57 This version of SSH is based upon code retrieved from the OpenBSD CVS
58 repository which in turn was based on the last free
59 version of SSH released by Tatu Ylonen.
