nodescan v0.7.1

Nodescan

I have a lot of things on my network and I don't even know what they are half the time. This is an alternative to fing which is pretty good, but you need to buy a license to get full control.

The main purpose of this is network recon to find and identify hosts.

Install

npm install -g

Develop

git clone https://github.com/walchko/nodescan.git
cd nodescan
npm install
npm link

OSX

brew install arp-scan

Linux

sudo apt-get install arp-scan

Usage

[kevin@Tardis nodescan]$ nodescan -h

  Usage: nodescan nodescan [options]

  Local network scanner with web interface

  Options:

    -h, --help              output usage information
    -V, --version           output the version number
    -d, --dev [interface]   network interface to use for scan, default: en1
    -l, --loc [location]    save file location, default location: ~
    -p, --port <port>       Http server port number, default: 8888
    -u, --update [seconds]  update time for arp-scan, default: 60 sec

Setup

For RPi, install this in /etc/systemd/system/nodescan.service, this will ensure it runs at start up.

[Service]
ExecStart=/usr/local/bin/nodescan -d eth0 -l /var/run
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=nodescan
User=root
Group=root
Environment=NODE_ENV=production

[Install]
WantedBy=multi-user.target

Then do:

sudo systemctl enable nodescan.service
sudo systemctl start nodescan.service

Now use a browser to go to <your rpi>:8888 and see the results.

You can also use sudo systemctl start|stop|status nodescan.service to start, stop, or find the current status of the server.

To Do

• Scan hosts for open ports (easy) and figure out a smart way to put that on the web page (harder)
• Save/recover network database from file, having issues reading file back in
• Do I need to show the mac addr? Is there a better way to do that?
• Maybe put a json interface?
• Turn on/off web interface, then just use json to get info?
• Add tests
