problems with snort&Base

Hi, I have installed snort with Base & mysql. now I have 2 questions:
1- where we should install snort on a subnet? on a Gateway? suppose I have a subnet and I want to install snort as my IDS to controll all the trafics go out and come in to the subnet. after a main router?

2- I have problem with graphic in Base. if I must to use jpgraph (In Linux)? or another package?
Now I have installed Image_Graph. but there is a problem: "Failed opening required 'Image/Canvas.php' ", but there is not any Canvas.php file on my system.

Thanks in advance.

Anything "central" will do if you want to sniff and that's all you have to work with.
If you want to actively control traffic have a look at Snort-inline.

I have problem with graphic in Base.
Sorry. Can't help you with that.
