This is *definitely* something that you need to think through.  I have two=20
machines at work that are always on, so I can always ssh to them first,=20
then to the server and edit the /etc/hosts.allow file to give myself=20
temporary access, if needed.  In general, I prefer to go through those=20
hosts, rather than open another avenue that I may later forget to remove.=20
Since everything I do on those servers (almost) is through ssh, it's not a=20
problem for me to need an extra "hop" before I get to the box.
