A Python implementation of TCP ping that tests connectivity to a remote host by attempting TCP connections. It measures connection establishment times and provides detailed statistics.

• 🚀 Pure Python implementation, no external dependencies
• 📦 Lightweight and easy to use
• 🌐 Supports both IPv4 and IPv6
• 🔄 Supports continuous ping mode

You can install tcpp directly from PyPI:

pip install tcpp

Basic usage:

tcpp bing.com

With custom port and count:

tcpp bing.com 443 -c 10

All available options:

tcpp [-h] [-c COUNT] [-t TIMEOUT] [-4] [-6] [-v] host [port]

positional arguments:
  host                  Target hostname or IP address to ping
  port                  Target port number (default: 80)

options:
  -h, --help           Show this help message and exit
  -c, --count COUNT    Number of pings to send (default: 10, 0 = infinite)
  -t, --timeout SEC    Connection timeout in seconds (default: 1.0)
  -4                   Force using IPv4
  -6                   Force using IPv6
  -v, --version        Show program version

You can also use tcpp as a Python library:

import tcpp

# Basic usage
stats = tcpp.ping("bing.com", port=80)

# Access statistics
print(f"Success rate: {stats.success_rate}%")
print(f"Average time: {stats.avg_time:.2f}ms")
