Portnut

Portnut is a port stressing / scanning multithreaded utility. It can handle raw TCP and HTTP.

TODO

Make a distributed version that allows stressing from multiple computers at the same time
When TCP stress testing, show results for each port.

Install

Go to the releases page and download the latest version. Give it execution rights and simply launch it.

Building

Prerequisite to building reqwest:

apt install libssl-dev

Usage

Portnut is a tcp port scanner / stresser.

The scanning function simply tries to connect to the tcp ports given. The stressing function sends a payload every 10 milliseconds, to every ports given at the same time. The payload can be passed via a pipe (optionnal).

TCP Stress

TCP Stress can be applied to a port, a list of port, or a range of port. Stressing allows sending a payload (via -p/--payload or via a pipe), sending, and waiting for an answer.

2356 justine > portnut tcpstress -a 127.0.0.1 -p 8080 -d 2

HTTP Stress

HTTP stress performs a GET on the given address.

A simple TCP/HTTP port scanner / stresser. If stressing, you can pass a payload via a pipe

Usage: portnut [OPTIONS] --address <ADDRESS> --ports <PORTS>... <MODE>

Arguments:
  <MODE>  Mode of use : either tcpstress, tcpscan or httpstress

Options:
  -a, --address <ADDRESS>    IP address or hostname to scan - or url if using http
  -t, --timeout <TIMEOUT>    Timeout for each connection in seconds [default: 1]
  -w, --wait <WAIT>          Number of milliseconds to wait in between scans or requests [default: 30]
  -d, --duration <DURATION>  Duration of tcp stress test in seconds, default 30 [default: 30]
  -p, --ports <PORTS>...     Ports to stress / scan, separated by commas (22,80)
  -r, --range                Set this flag to treat the ports as a range rather than a list
  -s, --stress               Set this flag to stress the ports instead of scanning them
  -c, --cthreads <CTHREADS>  How many threads per port when stressing (Concurrent Threads) [default: 5]
  -h, --help                 Print help
  -V, --version              Print version
