Setup virtual users instead of local users and configure user specific home directories for each user, or shared between a handful of users.

The reason for setting up virtual users, and different home directory for each user, was to allow ftp access to a web server running a number of different sites for different clients. Each client can have one or more login to the ftp server, and the usernames and passwords can be shared with the apache webserver, so you only need to store their passwords in one place.

I’m choosing vsftpd as the ftp server, as it seems to have the best reputation for being secure (and having the fewest security bugs)

 

Installing

Whilst each flavour of linux has it’s own way of installing software, I’m going to run through using debian, so you will need to adapt it for whichever distro you use.

Firstly we need to download and install the ftp server VSFTPD

debian# apt-get install vsftpd Read the rest of this entry »

There are many reasons people are hesitant to try Linux. The biggest of these reasons is that installing Linux generally requires people to do a list of difficult and unfamiliar tasks. However, I am going to introduce “virtualization” which is a fancy term for running Linux like any other program in Windows. The following article will guide you through the process of setting up Linux so you can run it like any other program in Windows. Don’t be intimated, these directions are designed for the absolute beginner and will not require you to do anything unfamiliar, threatening, or permanent to your computer. When you are finished you will be able to run Linux like any other program in Windows and share files between Linux and Windows.

We will learn to run squid with squidGuard that is a URL redirector used to use blacklists.
