A word of caution here. There have been plenty of previous releases of
OpenSSH that have been cracked, often for reasons external to it, like
the gzip compression library overflow, and more recent issues with
OpenSSL. Unless you really need cross-Internet access to a machine,
don't enable ssh logins on an Internet facing server. If you must have
remote access from the Internet, consider using something more secure
than than passwords for authentication. I use rsa/dsa key
authentication only. Even then, you must pay special attention to
security announcements that affect OpenSSH.
