"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 desired. Here's the basic format..."
"...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."
