(OpenSSL 0.9.5a is partially supported, but some ciphers (SSH protocol 1
Blowfish) do not work correctly.)

NB. If you operating system supports /dev/random, you should configure
OpenSSL to use it. OpenSSH relies on OpenSSL's direct support of
/dev/random. If you don't you will have to rely on ssh-rand-helper, which
is inferior to a good kernel-based solution.

If you wish to build the GNOME passphrase requester, you will need the GNOME
libraries and headers.

LibEdit:

-platform has it available natively you can use that, alternatively

+If you modify configure.ac or configure doesn't exist (eg if you checked

+the automatically generated files by running "autoreconf". Earlier

+Basic Security Module (BSM):
+
+Native BSM support is know to exist in Solaris from at least 2.5.1,
+FreeBSD 6.1 and OS X. Alternatively, you may use the OpenBSM
+implementation (http://www.openbsm.org).

2. Building / Installation
--------------------------
There are a few other options to the configure script:
+--with-audit=[module] enable additional auditing via the specified module.
+Currently, drivers for "debug" (additional info via syslog) and "bsm"
+(Sun's Basic Security Module) are supported.
+
--with-pam enables PAM support. If PAM support is compiled in, it must
also be enabled in sshd_config (refer to the UsePAM directive).
-------------------------
$ make survey
-[check the contents and make sure there's no sensitive information]
+[check the contents of the file "survey" to ensure there's no information
+that you consider sensitive]
$ make send-survey
This will send configuration information for the currently configured
