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
• Return more stats (low 1%, high 1%)

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
