RapidShare & Requests Per Second :(

[Robin H]

Hi

*$20 to the one that fixes mi shit *

I've got this feeling i'm being DoS'd by RS
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

If you had CentOS could've helped a lot .
I guess you will have to PM Whoo, hes a expert in Debian.

Alright
Thanks for pointing me to the right people

[desiboy]

apache right ?

try tuning the apache settings
in

/etc/apache2/apache2.conf

try altering these values

MaxKeepAliveRequests
MaxRequestsPerChild

Still thesame problem

try to lower them even more.

Also I dont think rs would ddos you

[desiboy]

^^ 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

This is getting fun :?

MaxKeepAliveRequests 5

<IfModule mpm_prefork_module>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 65
MaxRequestsPerChild 1
</IfModule>
<IfModule mpm_worker_module>

edit:
Desiboy, wont that result in failed remotes?

edit?:
Nope, still going to high:




EDDIDIIITIITITIT:
FFS, was in wrong server

another_edit:

Well, doesnt really matter, still nothing changed

edit:
Gonna try the IPtables shit, but with port80 instead of 22 ofcourse

[desiboy]

ya..port 80

[Robin H]

Is it foolproof because there's still no change

edit:

$20 reward :-/
