Network Connectivity Tester

A Python-based network connectivity tester that uses the scapy library to send ICMP (ping) requests to a list of hosts, measure the round-trip time, and log the results. It also plots the ping test results over time and uses matplotlib library to display the results in a functional graph after the run.

Installation

Make sure you have Python 3.x installed. Then, install the required Python modules using the following command:

pip install scapy matplotlib

Running the Script

Command-Line Arguments

• --hosts: Comma-separated list of hosts to ping (e.g., '8.8.4.4,1.0.0.1'). Default is 8.8.8.8,1.1.1.1.
• --duration: Test duration in seconds. Default is 30.
• --interval: Ping interval in seconds. Default is 1.
• --packet_size: Packet size in bytes. Default is 32.
• --ttl: TTL (Time to Live). Default is 64.
• --nolog: Skips the creation of a logfile.

Example Usage

1. Running with defaults (8.8.8.8, 1.1.1.1):

   python network_tester.py

2. Running with custom hosts and other arguments:

   python network_tester.py --hosts "8.8.4.4,1.0.0.1" --duration 10 --interval 2 --packet_size 64 --ttl 128 --nolog

Known Issues

• Windows Native Raw Sockets Error: On Windows, raw sockets require administrator privileges. You may encounter the following error:

  Error pinging 8.8.8.8: Windows native L3 Raw sockets are only usable as administrator !
  

  Solution:

  • Run the Script as Administrator:
    • In Windows, raw sockets (which are used to send ICMP pings) require administrator privileges.
    • If you are using Command Prompt, VSCode or any other software to run the code. Run the software elevated then try running the script again.
