-RPMs of OpenSSL are available at http://violet.ibs.com.au/openssh/files/support.
-For Red Hat Linux 6.2, they have been released as errata. RHL7 includes
-these.
+(OpenSSL 0.9.5a is partially supported, but some ciphers (SSH protocol 1
+Blowfish) do not work correctly.)
OpenSSH can utilise Pluggable Authentication Modules (PAM) if your system
supports it. PAM is standard on Redhat and Debian Linux, Solaris and
HP-UX 11.
+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.

There are a few other options to the configure script:
---with-rsh=PATH allows you to specify the path to your rsh program.
-Normally ./configure will search the current $PATH for 'rsh'. You
-may need to specify this option if rsh is not in your path or has a
-different name.

--with-pam enables PAM support.
--enable-gnome-askpass will build the GNOME passphrase dialog. You
