Linux Journal: You Can Get There from Here, Part 2

“Another type of protection you may want to consider when
remotely accessing your mail (or any other type of web
document/application) is Apache’s own access controls. You all know
about those nice little “you must enter your password” boxes that
pop up when you visit certain web sites. Well, you can do the same
for your Squirrelmail application. This is done with the .htaccess
file, which lives in the directory for which limited access is

“…Every once in a while, you need to get to your system.
Specifically, you need to get shell access. If you happen to be on
someone else’s network or, if you are not carrying your handy-dandy
notebook (computer), this can be a problem. The problem gets worse
if, being the security-conscious type that you are, you deny
Telnets in favor of an SSH connection. Just about every PC has some
kind of Telnet terminal application (though the standard one that
comes with that other OS tends to be pretty, ahem, crappy), but not
everyone has a SSH terminal for you to use. If you’ve got a web
server on your system, your problems are solved. Pretty much
anybody who is connected has a web browser, and that’s all you need
with Matthias L. Jugel and Marcus Meißner’s Java Terminal
app.”
