Make a distributed version that allows stressing from multiple computers at the same time

Install

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

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).

1637 justine@portnut > target/release/portnut -a 127.0.0.1 -w 3 -p 8080,22   
Scanning 127.0.0.1
TCP/8080 => REJECT
TCP/22 => REJECT

#First scan the ports, and stress the available ones.
1738 justine@portnut > echo "GET / HTTP/1.1" | target/release/portnut -a 127.0.0.1 -p 8080 -w 30 -s -c 100
Scanning 127.0.0.1
TCP/8080 => ACCEPT

Stressing 127.0.0.1 using 100 concurrent threads per port for 30s

See the help :

justine@portnut > target/release/portnut -h
