 Cygwin
 ------
 To build on Cygwin, OpenSSH requires the following packages:

+Darwin and MacOS X
+------------------
+Darwin does not provide a tun(4) driver required for OpenSSH-based
+virtual private networks. The BSD manpage still exists, but the driver
+has been removed in recent releases of Darwin and MacOS X.
+
+Nevertheless, tunnel support is known to work with Darwin 8 and
+MacOS X 10.4 in Point-to-Point (Layer 3) and Ethernet (Layer 2) mode
+using a third party driver. More information is available at:
+	http://www-user.rhrk.uni-kl.de/~nissler/tuntap/
+
+
+Linux
+-----
+
+Some Linux distributions (including Red Hat/Fedora/CentOS) include
+headers and library links in the -devel RPMs rather than the main
+binary RPMs. If you get an error about headers, or complaining about a
+missing prerequisite then you may need to install the equivalent
+development packages.  On Redhat based distros these may be openssl-devel,
+zlib-devel and pam-devel, on Debian based distros these may be
+libssl-dev, libz-dev and libpam-dev.

 Solaris
 -------
-Currently, sshd does not support BSM auditting.  This can show up as errors
-when editting cron entries via crontab.  See.
-http://bugzilla.mindrot.org/show_bug.cgi?id=125
+If you enable BSM auditing on Solaris, you need to update audit_event(4)
+for praudit(1m) to give sensible output.  The following line needs to be
+added to /etc/security/audit_event:
+
+	32800:AUE_openssh:OpenSSH login:lo
+
+The BSM audit event range available for third party TCB applications is
+32768 - 65535.  Event number 32800 has been choosen for AUE_openssh.
+There is no official registry of 3rd party event numbers, so if this
+number is already in use on your system, you may change it at build time
+by configure'ing --with-cflags=-DAUE_openssh=32801 then rebuilding.
+
+
+Platforms using PAM
+-------------------
+As of OpenSSH 4.3p1, sshd will no longer check /etc/nologin itself when
+PAM is enabled.  To maintain existing behaviour, pam_nologin should be
+added to sshd's session stack which will prevent users from starting shell
+sessions.  Alternatively, pam_nologin can be added to either the auth or
+account stacks which will prevent authentication entirely, but will still
+return the output from pam_nologin to the client.
