find-sshable 0.2.2

Tool to find ssh-able devices on your network.

Find SSH-able

Find SSH-able devices on your network and (optionally) add them to you ssh config in a cleanish way. Tested locally with MacOS and runs with Actions on Ubuntu.

Works by stringing together a couple nmap commands and updating the ssh config file.

# find open port 22
nmap -sT -p 22 -T5 <network>
# check ssh auth methods
nmap -p 22 --script ssh-auth-methods <target>

Setup

1. Install nmap

   # MacOS
   brew install nmap
   # Debian
   sudo apt-get install nmap
   

2. Install the script in $HOME/bin (hopefully on your path)

   ./install.sh
   

3. Run the program

   find-sshable --help
   

Python Package

pip install find-sshable

Testing

# pip install pytest
PYTHONPATH=. pytest -vs .

Headless Raspberry Pi

The idea is to stand up a headless raspberry pi that you can ssh into and do things on.

If you will run this on Wifi (not ethernet), start from here to configure the WiFi on your raspberry pi. However, if you can connect to ethernet, I would recommend doing so, and you can skip this step.

As per here add an empty ssh file to the root partition when you frist boot up.

Locally run the following. This will find and add your Pi to the local ssh config.

find-sshable --host-pattern "raspberrypi" --update-ssh-config --ssh-user "pi"

    scanning for devices... 00:07

    Found 1 devices...
    Host(name='raspberrypi.lan', ip=IPv4Address('192.168.86.36'))

    Devices will be added to your ssh config as follows
    find-sshable.raspberrypi.lan    192.168.86.36

ssh into it,

ssh find-sshable.raspberrypi.lan

On there, you should change your password, update locale, etc

sudo raspi-config

Also ensure that ssh runs on start up

sudo systemctl enable ssh
sudo systemctl start ssh
