netstat Command Examples in Linux¶

Introduction¶

These examples show practical ways to use netstat on a Linux terminal. Each example is written so you can adapt it for administration or troubleshooting.

Example 1: Basic Usage¶

netstat -tuln

This is the simplest form of the command and is a good starting point before adding options.

Example 2: Common Admin Task¶

netstat -rn

This example reflects a common task on RHEL, Rocky Linux, AlmaLinux, or similar systems.

Example 3: Useful Option¶

netstat -tulpn

This option helps narrow the result, change behavior, or handle a more realistic target.

Example 4: Real-World Scenario¶

netstat -an | grep 443

Use this pattern when the task moves beyond a single basic command.

Example 5: Verification¶

netstat -s

Example output:

tcp        0      0 0.0.0.0:22        0.0.0.0:*        LISTEN

Common Mistakes¶

• Assuming netstat is installed on minimal systems.
• Using netstat by habit when ss gives clearer modern output.
• Forgetting -n, which can slow output while names are resolved.

Quick Reference¶

netstat -tuln
netstat -rn
netstat -tulpn
netstat -an | grep 443
netstat -s
