preload-slowloris

This library hooks the send(2) and socket(2) symbols and forces the data on sockets of SOCK_STREAM type (most likely TCP, might also work on other stream protocols) to be split into multiple segments for transmit.

Building

Running make should suffice on a system with a working C compiler.

Usage

Force the library to be loaded using LD_PRELOAD

LD_PRELOAD=./slowloris.so curl 10.23.25.3

A delay between individual send() calls (in microseconds) can be set by providing SLOWLORIS_DELAY. The default delay is 0.

SLOWLORIS_DELAY=1000 LD_PRELOAD=./slowloris.so curl 10.23.25.3

The number of bytes sent per iteration can be set by supplying SLOWLORIS_CHUNK. The default chunking is 1.

SLOWLORIS_CHUNK=10 LD_PRELOAD=./slowloris.so curl 10.23.25.3
