tping - TCP Port Connectivity Test

The tping module uses curl to perform TCP connection tests to specific ports on a target host. It is ideal for verifying service availability when ICMP (standard ping) is blocked.

When to Activate

• When testing if a web server (port 80/443) or custom service is reachable.
• When standard ICMP ping is disabled by a firewall on the target.
• When needing visual metrics (heatmap/bar) for TCP connection times.

Core Principles & Rules

• Port Specificity: Allows testing connectivity to any TCP port (default is 80).
• Visualization: Supports the same heatmap and bar chart modes as the enhanced ping module.

Patterns & Examples

Basic Port Check

# Test TCP connectivity to port 80 of a domain
x tping bing.com

Custom Port with Visualization

# Check port 443 with a real-time bar chart
x tping --bar bing.com:443

Checklist

• Confirm the target host and port number.
• Verify if standard ping is insufficient for the task.
