All my searching has turned up nothing, so I'm guessing there may be no
way to do this without additional programs installed. There doesn't
appear to be any switches that can be used with sshd, scp, etc. that
will display this information.
Any help would be appreciated.
The successful SSH connections made are normally loged in /var/log/secure, I
believe. It should be simple to parse those logs to report active
connections. However, that logfile often contains sensitive information,
such as mistyped logins when someone accidentally puts their password in as
their login name, and should thus not be parsed and published without some
careful thought.

What I describe above would require an add-on monitor program.
have a look at "logwatch". Somewhere under /etc is a config file that
needs a little editing: fill in your mail address and the level of
precision (0 - 10). You won't get the filenames but the users and kb's.
