What do you use to prevent clients overloading server?

[[JSH]John]

I'm just wondering what you all use to prevent clients from using a lot of CPU/RAM? I've had this problem lately and I can't seem to find any scripts to help with this.

OS: CentOS 5.2

If your technical skills aren't upto it - use CSF and it's process killer :)

I monitor things and watch logs etc - i've a few custom bash scripts I fire off during the day to scan for things and watch what's going on with the server.

Use mytop to monitor MySQL usage.

Thanks Technics :) I do use CSF along with the process killer but now it has been tweaked so that it should now work better. I sort of forgot all about that so the settings were pretty much default.

We rarely manually look into the servers. WHMCS offers a one page look at the load status of all the servers.

With a brief idea as to how many accounts are on that server with the load status depicted, you'll know if the system is being abused or if it is general server activity.

cPanel's "Apache Status", "top" and "mytop" should do everything you might want. Use it along with iptables incase of an attack and your safe!

You aren't serious are you? :eek3:

Try the process resource moniter here: http://www.rfxnetworks.com/prm.php

Yep, I am serious. Keyword there is "manual". Read the rest of my post before judging.

Edit: Once there is problem, its obvious that someone will look at the server. But as a routine, no manual intervention. All automated (for that read previous post).

Yes you have to do manual checks look at server logs and whos hogging the most resources. I probably susspend 40 accounts out of 50 new signups each day.
