Send IP

Python software to configure machines for sending their IP through ssh.

Installation

You are advised to create a virtual environment for this program:

conda create -n "send_ip_env" 
conda activate send_ip_end

Run the following to install:

pip3 install send_ip

Running from a virtual environment will affect the python path that you supply to config.yaml. See information in Usage section.

Usage

1. Edit the config.yaml file to match your destination. These fields will be used to scp into the target machine (user@ip:port using password pass to login).

user: target-user
ip: ip-address
pass: target-password
port: target-port #default port is usually 22 
remote-path: target-folder # this folder will be created under /home/user might create errors for not linux users
refresh-freq: 15 # minutes for cron-job
python_path: /path/to/virtualenv/bin/python3 # the python path you supply here will affect where the code runs (e.g., /usr/bin/python3), see docs! 

2. Use the pacakge functions, for example:

from send_ip.send_ip import *

info_file = create_info()
send_info(info_file)

You can save this into a send_ip_script.py and schedule this task to run automatically (see below)

Schedule task

Cron

You can setup send_ip_script.py to run on a schedule (e.g., every 15 minutes). For example, this is the configuration for a raspberry pi (pi) sending its IP to another machine (matias) using config.yaml.

from send_ip.setup_cron import setup_cron
setup_cron("/home/pi/send_ip/send_ip_script.py",15)
Current cron tab (same as $ crontab -l)
--------------------------------------

*/15 * * * * cd python3 /home/pi/send_ip/ && /home/pi/send_ip/send_ip_script.py # send ip to matias

Windows machines

Please refer to this example and file issues if having trouble.

For developers of send_ip

To install send_ip and tools needed for tests, you can install into a virtualenvironment like so:

pip install -e .[dev]

Known issues

For a Raspberry pi installation, you might face this issue:

          If you are seeing a compilation error please try the following steps to
          successfully install bcrypt:
          1) Upgrade to the latest pip and try again. This will fix errors for most
             users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
          2) Ensure you have a recent Rust toolchain installed. bcrypt requires
             rustc >= 1.56.0.
      
          Python: 3.9.2
          platform: Linux-5.15.56-v7l+-armv7l-with-glibc2.31

You might need:

sudo apt-get install build-essential cargo

You can also refer to this info in bcrypt.

You might also need to install or upgrade rustc
