All.

I'd like to get a free tool running on linux that can easily get some netflow data from a Cisco device. There seems to be no easy way to do this.

What are you guys running on linux to get Netflow-specific data?

I too was going to use Cacti for it. There is a plug-in for it called Flow Viewer. I run Cacti on Windows won't work but it will on Linux.

I've used NTOP (http://www.ntop.org/) for this before, but keep in mind that you're limited to about 64 subnets due to a variable in the initial source files. You can edit one of the source files to increase this, but I've never gone above 128 subnets without seeing strange errors.
