* The 'kex guesses' bugfix from OpenSSH 3.6 triggers a bug in a few other SSH v2 implementations and causes connections to stall. OpenSSH 3.6.1 disables this bugfix when interoperating with these implementations. * RSA blinding is now used by ssh(1), sshd(8) and ssh-agent(1). in order to avoid potential timing attacks against the RSA keys. Older versions of OpenSSH have been using RSA blinding in ssh-keysign(1) only. * ssh-agent(1) optionally requires user confirmation if a key gets used, see '-c' in ssh-add(1). * sshd(8) now handles PermitRootLogin correctly when UsePrivilegeSeparation is enabled. * sshd(8) now removes X11 cookies when a session gets closed. * ssh-keysign(8) is disabled by default and only enabled if the new EnableSSHKeysign option is set in the global ssh_config(5) file. * ssh(1) and sshd(8) now handle 'kex guesses' correctly (key exchange guesses). * ssh(1) no longer overwrites SIG_IGN. This matches behaviour from rsh(1) and is used by backup tools. * setting ProxyCommand to 'none' disables the proxy feature, see ssh_config(5). * scp(1) supports add -1 and -2. * scp(1) supports bandwidth limiting. * sftp(1) displays a progressmeter. * sftp(1) has improved error handling for scripting.
This release of OpenSSH is for OpenBSD systems only. Please read http://www.openssh.com/portable.html if you want to install OpenSSH on other operating systems. To extract and install this release on your OpenBSD system use: # cd /usr/src/usr.bin # tar xvfz .../openssh-x.y.tgz # cd ssh # make obj # make cleandir # make depend # make # make install # cp ssh_config sshd_config /etc/ssh OpenSSH is a derivative of the original and free ssh 1.2.12 release by Tatu Ylonen. Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo de Raadt and Dug Song removed many bugs, re-added newer features and created OpenSSH. Markus Friedl contributed the support for SSH protocol versions 1.5 and 2.0. See http://www.openssh.com/ for more information.
