Ping Network Diagnostic Tool

A simple Bash script leveraging the ping command to test network connectivity and gather diagnostic information.

Overview

The ping command sends ICMP echo request packets to a specified target, awaiting echo reply packets. Different outcomes are explained below:

Possible Outcomes:

• Valid and Reachable Address:

  • Successful echo replies with statistics about the time taken, TTL, and other details.

• Valid but Unreachable Address:

  • Indicates the host or network is unreachable, often displaying "Request timeout" messages.

• Invalid Address:

  • Error messages indicating name resolution failure or address invalidity.

• Network Issues:

  • Errors pointing toward unreachable networks or other connectivity issues.

• Firewalls/Security Settings:

  • Some hosts might not respond due to firewall or security configurations blocking ICMP packets.

• Local Configuration Issues:

  • Failures related to the user's machine's network configuration or DNS resolution.

Usage

./ping_script.sh <target-address>

Replace <target-address> with any valid IP address or domain name.

Note

While ping is a valuable diagnostic tool, it's essential to remember that it's just one among many. For in-depth diagnostics, consider other network tools and techniques.
