IP Services and Port Probes

4 min read
On this page

In this lesson, you will learn:

  • What an IP service is
  • What a port probe does
  • How SNWR added port 8465

🔁 Quick look back: Last time: Discovery Behaviors and Functionality Definitions. You learned how behaviors send each protocol to the right MID Server.

1 The Problem: Discovery Doesn’t Know About Port 8465

The SNWR Mail Archiver listens on port 8465. Discovery’s scanning step doesn’t check that port. So:

  • It doesn’t notice the archiver’s port is open.
  • Nothing points Discovery at the app.

🎯 The problem: Discovery doesn’t know about port 8465.

👉 The fix: Add an IP service for port 8465, so the scan notices it.

2 IP services and port probes

Key term: IP service

A named port and protocol, such as SSH on 22/TCP.

Key term: Port probe

The scanning step that checks whether ports are open on each address.

Open ports help classify devices and point to applications.

3 Adding a port

  1. Create an IP service with the name, port and protocol.
  2. Check it’s included in the port checks used by your schedules.
  3. Run a test scan and look for the port in the results.

⚠️ Heads up: Only add ports you need. Every extra port makes scans a little longer.

4 Project Clear View: How We Implemented It

📍 Situation: The archiver’s port wasn’t being noticed.

🧭 Decision: Add an IP service for 8465 and test.

🛠️ Steps we took:

  1. Created IP service snwr-archiver on 8465/TCP on snwrdev.
  2. Checked the scanning step includes it.
  3. Ran Quick Discovery on the lab copy of the archiver.
  4. Saw 8465 recorded as open.

✅ What we verified:

  • Port 8465 appears in the results.
  • No other ports were added.

📁 Evidence: The IP service, listed in the migration matrix.

5 Quick recap

  • An IP service is a named port and protocol.
  • The port probe checks which ports are open.
  • Open ports help classify devices and find apps.
  • Add only the ports you need.

1 What is an IP service? Show answer

A named port and protocol, like SSH on 22/TCP.

2 Which port does the SNWR Mail Archiver use? Show answer

8465/TCP.

3 Why not add many ports? Show answer

Each extra port makes scans longer.

Nice work! Discovery now notices the archiver’s port. 🎉
