ssh Command Examples in Linux¶

Introduction¶

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

Example 1: Basic Usage¶

ssh admin@server.example.com

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

Example 2: Common Admin Task¶

ssh admin@server.example.com hostname

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

Example 3: Useful Option¶

ssh -p 2222 admin@server.example.com

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

Example 4: Real-World Scenario¶

ssh -i ~/.ssh/id_rsa admin@server.example.com

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

Example 5: Verification¶

ssh -V

Example output:

OpenSSH_9.6p1, OpenSSL 3.0.7 1 Nov 2022

Common Mistakes¶

• Using the wrong remote username.
• Leaving private key permissions too open.
• Troubleshooting authentication without trying ssh -v for useful details.

Quick Reference¶

ssh admin@server.example.com
ssh admin@server.example.com hostname
ssh -p 2222 admin@server.example.com
ssh -i ~/.ssh/id_rsa admin@server.example.com
ssh -V
