Quick Note on OS For the installation of Snort, we are going to use Ubuntu 10.04, 32 bit. I don't personally use Ubuntu often, but anyone reading this tutorial is more likely to use Ubuntu for their Linux variant and I want people to be comfortable with their OS. This is important for troubleshooting issues and for ensuring their deployments stay secure. How many Windows Server Admins out there deploy a Linux box for one specific purpose and never keep up-to-date with patches? I've seen too many and I know a younger me was caught in this trap. Other Operating Systems Check out Snort's website for other operating systems:.
Do realize that these guides are not written with the intent of installing Snorby as the front-end. Those documents are still stuck in the days of BASE, so ignore that part if you want Snorby.

Using apt, you will lose some functionality and you are at the mercy of the repository and package managers.

The preferred method is compiling from source, but some users may feel uncomfortable with that method.
