Sorry for the delay in getting back to this. I want to log this activity on
a Red Hat server where multiple users log in as 'root'. Not really hunting
for malicious activity, just to see if the bash_history can record the login
IP or hostname. Some users come in from different locations, so it's more of
a security/activity accounting thing. For the time being, worries about
users trying eliminate the history aren't really a concern, simply logging
the activities of users coming in from different hosts (and separating their
commands by host) is.
