Linux + Windows port 80 attacks - Crashing your website.

[kito2]

Hello everyone, I use Linux and noticed that a friend know how to attack a website and crash it, he said that are floods attack.
And some times it lags the OT and also he can crash it.

And it just crash tibia websites, anyone knows how to fix this?

Apache or nginx?

 

[kito2]

I use apache and lighttpd on Linux, xampplite for windows.

 

[chojrak]

Maybe limit connections per IP for port 80 using iptables?

 

[bolero]

Sure, but how to install or configurate this application?

For example, as we set this up, chojrak, if you know how Tell us please.

 

[chojrak]

Iptables Limits Connections Per IP
Learn to use google.

Also I'm not sure if that's gonna work, it's just idea.

Found a fix: Instalar fail2ban En debian Y centos… How To

 

[bolero]

I use ubuntu :/... I don't think this solve my problem.

Let's see, I am that I have the program to attack, I can crash down most of the websites that are warm, but not be repaired until my website is vulnerable, and do not think the link you give me, work... I was Talk to Stian but do not want to help the community.

If you want to tell me some ip and attacked, you see.

This is the best I can find as a guide for IPTables from here on you're on your own, but if you follow this guide and ask other users that are more advanced in linux you might be able to set it up right.
HowTo: IP Tables

 

[Debian]

It serves perfectly for attacks DOS and DDOS and proved a mod with the same name but from Apache I hope that it has them same in lighttpd
But it is not a definitive solution for these attacks

 

[bolero]

I can't know how to install this debian ~~!

 

[kito2]

Same here... Im pretty new here using linux, and just know how to compile and run website and OT, but those things for me are to much... I use Debian Lenny 64 bits, which shall I download :S?

I looked at the link and this is the one you have to download: 10.6/x86_64 since your computer is 64-bit for anyone else they have to use i386(32-bit).

Please debian, post your guide to install the block packets.

 

[Debian]

a simple way (for now) would open lighttpd.conf and here you have two options (of course if you uncomment these lines are commented):

limit all the bandwidth it occupies lighttpd (example limits it to only handle 1024 kbyte / s)

server.kbytes-per-second=1024

bandwidth limit ke you give each user (ip) to visit your site (for example put 64 kbyte / s)

connection.kbytes-per-second=64

 

[bolero]

And If I change the 64kbps for more kbps what happen? What are the maximun kbps use one player?

And if I want to unistall this how I can?
