Terminology: the "shell" is the command-interpreter, or its equivalent
(e.g. a login via XWindows). A "limited shell" is one that will not
consent to obey all of the commands that, say, "bash" would.

The firewall can be told to "drop" the packets, or to "reject" them. And
the firewall can be told to produce a log entry, or not. If the packets
are dropped, the remote user has no way to know what happened to them. If
they are rejected, he'll get "connection refused." That might be useful
for now, just as a way of determining whether or not the packets are
arriving at your door.

Lots of hosting-providers use software designed for the purpose, like Plesk.
This simply packages all the various "necessary evils" into one convenient
place that's easy to manage. If you're serious about providing hosting
(and I might not add, "why not let someone /else/ do it for you,
instead?"), those packages might be worth looking in to.
