Meyesl

Meyesl is a nonblocking port scanner, written to help me learn Ocaml 🐪

Using It

$ git clone https://github.com/jmsdnns/meyesl
$ cd meyesl 
$ make
$ meyesl 127.0.0.1

How It Works

More elaborate usage looks like this

$ meyesl 127.0.0.1 -p 22,80,8000-8099,9999

PORTS

The -p flag is for specifying which ports to scan. Ports can be expressed as:

• list of numbers: eyes -p 22,80,1336
• range of numbers: eyes -p 22-80
• mix of both: eyes -p 22,80,8000-8099,443,8443,3000-3443

TIMEOUT

The -t flag controls how long to wait on a connection that isn't opening before decided it's just not reachable.

The default timeout is 3 seconds.
