20USD - RapidShare & Requests Per Second :(

Hi :))

*$20 to the one that fixes mi shit :D*

I've got this feeling i'm being DoS'd by RS :P
I'm hosting a script ( rs2rs.com <_< ) that acts as a proxy for RapidShare files.

But with every file running, I get about 70-80 Requests per second.
A server does about 60 files at once... So that adds up.

So... Is there any way to limit the amount of reqs/sec for an IP-range?
Running Debian

^^ its already less :))
iptables might be your friend ;)

just to give some idea what ip tables can do..you can run this commands which will drop incoming connections which make more than 10 connection attempts upon port 80 within 1 min
iptables -I INPUT -p tcp --dport 80 -i eth0 -m state --state NEW -m recent \
--update --seconds 60 --hitcount 10 -j DROP

EDDIDIIITIITITIT:
FFS, was in wrong server xD

another_edit:

Well, doesnt really matter, still nothing changed

edit:
Gonna try the IPtables shit, but with port80 instead of 22 ofcourse
 
Well, those methods has been posted before.
And I guess it blocks connections, not requests.

Anyway, I actually got this solved.

Problem was the bandwidth monitor & speed limiter.
It made a request with every package I guess.

Disabled it, and load dropped allot, servers are stable again, but ofcourse now everyone is exploiting the bandwidth.
But thats gonna end soon.

Splitice once wrote a speed-limit shit for me in the past. (He's worth every penny :D )
But because it was on a /file basis, and not on a /user shit, it was pretty hard to guarantee speeds.

I learned allot because of his scripts and now i'm gonna relook his idea.
