I'm working through this tutorial and have hit a bit of a roadblock. Starting at 'Prepping the Windows Intrusion Detection System (WinIDS) Master Sensor', there seems to be an assumption that I already have mySQL installed, and that there's already a database called 'snort'. But I can't find anything in the tutorial about installing MySQL or creating that database or its tables. I checked the various scripts in the WinIDS package (winids-cssp-x64.zip), and didn't find anything there either. What am I missing?

This is a Slave install, and it requires a master sensor being installed. The natural order of things would be to install a Master. Than a slave would be installed into any remote network not directly connected to the Master sensor.

That's the conclusion I came to as well, but I looked around in the tutorials and didn't see one that looked right. In my case, the Master will be on a 64-bit Linux server. Can you perhaps point me to the appropriate tutorial?

Look on Snort.org in the documentation section. There are usually a collection of different installs.
