That's the idea: 1 second to find a device.

Find running services

hoo list web

NAME       | IP           | MAC
-----------|--------------|------------------
myphone    | 192.168.1.76 | 64:a3:XX:XX:XX:XX

Use another program

hoo ssh myphone

Will execute: ssh <ip of myphone>

You can use any program, not just ssh.

Use as a lib

require 'hooray'
Hooray::Seek.lan(port, protocol).nodes
Hooray::Seek.new(network, port, protocol).nodes

• Nil port means ICMP ping.
• Protocol always defaults to :tcp.
• Network defaults to LAN IP 24 bits masked.

Possible protocols: tcp, udp, http, wmi & icmp (requires root).

Why?

Bind macs or fix IP's is also boring and a per device/node work. As more we use connected (IoT) devices in our company, nmap gets boring. Not to mention slow, there's no easy way to assign names to devices I know, which makes OS scan/port scan a needed option most times (thus making it slower). Also (please open a issue if you know how) even in fast mode nmap won't run in under 2s. And, on recent updates, you need sudo for all of that.

How?

hoo init

A ~/.horray folder is prepopulated: devices.yml regex list you mac addresses with names you recognize. services.yml regex list ports to names you recognize.

• Ruby net-ping gem.
• Nmap`s mac precompiled prefixes.

Hooray should work on UNIX based systems. Tested in Linux and OS X.
