Dataparty with 100-120 participants

post #1 of 32
Thread Starter 
Good morning,

We are going to arrange a dataparty for the second time in March, and we'd like to do something way better network-side than we did last time. Last time we used a bunch of "10/100/1000 PRO NETWORK 019191" switches which didn't give us much control over the network. We also used a pfSense firewall which worked quite nice.

This time we are going to do something much better network-side, so we have decided to purchase the following for the network:
- 1x Cisco SB 200 16 x Gigabit + 2 SFP as the coreswitch
- 1x HP ProCurve Switch 1810-24G as the switch that connects everything to the core
- undecided amount of HP ProCurve Switch 1410G-16s as edge/tableswitches

We will use a pfSense firewall this time aswell, but I have a few questions regarding monitoring and setup of everything here, just so we get everything straight.

First off, we are going to run some sort of network overview/monitoring so we can see what's actually happening, the core and the switch that connects everything has SNMP afaik, so we will be using something like Cacti or PRTG to monitor - do you know of any other programs that we can use (preferably with auto-discovery) to monitor the network?

I am also quite worried about skiddies screwing around with sniffers and whatnot, maybe even pull off a DoS against our equipment - how would we detect/block this kind of stuff? I know that we can setup a port to mirror everything on, then run Snort on one of our servers to detect it - the problem is that the amount of pps is probably going to be huge, and I doubt the hardware we have at hand will be capable of handling it, ideas?

Last but not least, how would you go on blocking/restricting p2p? We have been thinking of going the approach of setting up queues in pfSense, finding the ports for the most played games (or every game..) and placing them in the Premium queue, then we set up web and everything else in the Prioritized queue, and then we send all other (unknown) traffic to the Other queue where it would get limited to 300 - 400 Kbit/s. Is there any other way of doing this?

So basically, any ideas/programs or anything really is really appriciated.

Sounds like you have a good grasp on it.

I personally use Cacti at home and I find it's confusing at first. But it's a very powerful tool to monitor your systems. Your idea for pfSense is great. Using the queues and placing the games that are in demand ontop. You can also set speed limits too, so if you find you want to block youtube lets say, just set the speed limit to 1k/sec.

You could also place an Untagle box after your pfSense machine. Use this to filter traffic. So no porn or such.

Good luck!

Just my two cents, but I think the SB200 is a little low end for 100-120 participants. For what you're doing, that's a lot of workload on that switch. I've seen the SB200 pass a lot of data and literally shutdown due to overheating. I'd go with a heavier duty Cisco Catalyst Gigabit for your core.

Otherwise, I agree with your methodology. For network scanners or any internal DDOS attack, with good switches, you can shut that down on the switch level using BPDU Guard where they surpass a threshold and their port goes into error-disable. And when they say their internet doesn't work, you know where to look for the perp.

Any other switches you can recommend as the core except of the Catalysts?

Do you know if the "HP ProCurve Switch 2510G-24" is easy to configure & setup? I mean, is it just connect the console cable > set ip on switch > connect other cables > good to go?

You can get older 10/100 catalyst switches that are 48 port on the cheap. They are nothing extraordinarily speedy, but are reliable. Also getting a used 4006 chassis + couple of 48 port modules would be perfect for this. Heck Id give you one of my spares if it weren't for shipping biggrin.gif

I don't know right off the top of my head, but I read on the review on the egg that it has a web interface for configuration. So, to me it sounds like it's not too bad to configure.

We're gonna go with the HP ProCurve Switch 2510G-24 as the core, hopefully it wont be too hard to set up.
