Agent skill

tping

Ping TCP ports using curl to test service availability and network connectivity. Core Scenario: When the user needs to check if a specific TCP port (e.g., 80, 443) is open and responsive.

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

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

Custom Port with Visualization

bash
# 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.
