1 [ A Japanese translation of this document is available at 2 [ http://www.unixuser.org/%7Eharuyama/security/openssh/index.html 3 [ Thanks to HARUYAMA Seigo <haruyama@nt.phys.s.u-tokyo.ac.jp> 4 5 ******* IMPORTANT 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. 11 12 This is the port of OpenBSD's excellent OpenSSH[0] to Linux and other 13 Unices. 14 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/ 22 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. 29 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. 33 34 OpenSSH depends on Zlib[2], OpenSSL[3] and optionally PAM[4]. 35 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. 38 39 Please send bug reports and patches to the mailing list 40 openssh-unix-dev@mindrot.org. The list is open to posting by 41 unsubscribed users. 42 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 47 style guidelines[5]. 48 49 Please refer to the INSTALL document for information on how to install 50 OpenSSH on your system. There are a number of differences between this 51 port of OpenSSH and F-Secure SSH 1.x, please refer to the OpenSSH FAQ[6] 52 for details and general tips. 53 54 Damien Miller <djm@mindrot.org> 55 56 Miscellania - 57 58 This version of SSH is based upon code retrieved from the OpenBSD CVS 59 repository which in turn was based on the last free 60 version of SSH released by Tatu Ylonen. 61 62 References - 63 64 [0] http://www.openssh.com/faq.html 65 [1] http://www.lothar.com/tech/crypto/ 66 [2] ftp://ftp.freesoftware.com/pub/infozip/zlib/ 67 [3] http://www.openssl.org/ 68 [4] http://www.kernel.org/pub/linux/libs/pam/ (PAM is standard on Solaris) 69 [5] http://www.openbsd.org/cgi-bin/man.cgi?query=style&sektion=9&apropos=0&manpath=OpenBSD+Current 70 [6] http://www.openssh.com/faq.html
