TTL OS Guessing Tool

Description

The TTL OS Guessing Tool is a simple Python script designed to guess the operating system of a remote host. It uses the Time To Live (TTL) value from the ping response, as different operating systems set different default TTL values for their IP packets.

How It Works

  1. OS Detection: Detects the OS of the host running the script to use the correct ping command syntax.
  2. Ping Execution: Pings the specified IP address(es) and captures the TTL value from the response.
  3. OS Guessing: Makes an educated guess about the target system's OS based on the TTL value (Windows typically uses 128, Unix/Linux uses 64).
  4. Input Options: Users can input a single IP with -i or a list of IPs from a file with -l.

Note

This tool is a basic utility for quick guesses and not an advanced diagnostic tool.
