How to Use SSH to Connect to a Remote Server: A Beginner’s Guide

Have you ever needed to access a computer that’s not right in front of you — maybe to manage a website on a remote server or fix a technical problem from another location? That’s where SSH comes in handy.

This guide is here to help beginners get comfortable with remote access using SSH. Whether you’re a web developer, a system admin, or just curious about how it all works, we’ll walk through the basics step by step — and show you how to use SSH on Windows, macOS, or Linux.

How Do I Connect to a Remote Server Using SSH?

If you’re using Linux or macOS, you likely don’t need to install anything—SSH support comes built-in, so you can get started right away. On Windows, you might need to install an SSH program like PuTTY, although many newer versions already include OpenSSH through PowerShell.

To connect, open your terminal and type:

ssh username@host_address

Replace username with your server login name and host_address with the server’s IP address or domain name.

After that, you’ll be prompted to enter a password—or use your SSH key if it’s set up. Once you’re in, it’s like sitting in front of the remote computer, ready to work.

What are the real benefits of using SSH?

SSH makes working with remote systems easier and safer. Here’s what it brings to the table:

• Everything stays private – Your data is encrypted, so no one can snoop on what you’re sending or receiving.
  
• Remote control from anywhere – You can connect to your server from across the world and manage it like you’re sitting right there.
  
• Safe file sharing – Tools like SFTP and SCP let you transfer files without risking security.
  
• Tunneling other services – SSH can also act like a secure bridge for other apps, helping you access tools or databases behind firewalls.
  
• Login with keys, not passwords – SSH keys offer a safer and faster way to log in, and you can skip the password step altogether.
  
• Great for cloud servers – If you’re managing cloud hosting, SSH is a must-have.
  
• Multiple sessions, one connection – Multiplexing allows you to open several sessions without slowing things down.

Are there any downsides to using SSH?

SSH is a powerful tool, but it’s not foolproof. Here are a few things that can go wrong:

• Losing control of your keys – If someone gets access to your private key, they might get into your system.
  
• Tunneling gone wrong – While port forwarding is useful, it can unintentionally bypass security policies if you’re not careful.
  
• Slow networks can be annoying – A poor connection can lead to frustrating delays while working remotely.
  
• Bad setup = big risk – Mistakes in configuration can leave your system vulnerable, even if you’re using SSH.

So, is SSH still worth it?

Without a doubt. Even with a few hiccups, SSH is one of the best ways to securely connect to remote systems. Once you get used to it, it becomes second nature—and you’ll have the confidence to manage files, run commands, and fix problems from anywhere, knowing your connection is safe.

How to Use SSH to Connect to a Remote Server

If you’re trying to securely connect to a distant computer—whether a home server, a cloud host, or a community dev environment—SSH (Secure Shell) is the solution. It’s feature-rich yet straightforward way of managing servers, transferring files, and running commands over the internet remotely without compromising on security.

What You’ll Need Before You Start

In preparation for using SSH in accessing a remote server, make sure to have:

• An SSH client: macOS and Linux both include one. Windows either comes with OpenSSH, which is used, or can utilize a tool such as PuTTY.
• Remote server access: The server will need to have SSH activated and be accessible through its IP address or domain name.
• Credentials: You will need the username and either the password or SSH key associated with the server account.

Connecting with SSH from Different Operating Systems

On Linux and macOS

These systems have SSH ready to go. Open your terminal and enter:

ssh username@server_ip

Just replace username and server_ip with your actual login and the server’s IP address.

On Windows

Windows 10 and newer versions have OpenSSH in PowerShell. Use the same command format:

ssh username@server_ip

For older versions or a graphical interface, install PuTTY. Open it, enter your server’s IP, set the port to 22, and click “Open.”

Ways to Authenticate

Using a Password

This is the default method. After you run the SSH command, the server will prompt you for your password.

Using SSH Keys (Recommended)

This method is more secure and avoids typing your password each time.

• Generate a key on your machine:

ssh-keygen

• Copy the public key to your server:

ssh-copy-id username@server_ip

• Now connect without needing a password:

ssh username@server_ip

Additional SSH Options

• Custom port: If your server uses a different port:

ssh -p 2222 username@server_ip

• Specify a private key:

ssh -i /path/to/key username@server_ip

Final Tips for Safe Connections

• Avoid logging in as root; use a regular user account and sudo for admin tasks.
• Stick to strong passwords or key-based login.
• Keep your SSH software updated to stay protected from vulnerabilities.

SSH Login Commands: Examples and Best Practices

After getting your SSH server up and running, the second thing is being mindful about how to login securely and safely. Whether you’re administering a cloud server or merely remote-controlling your local box, controlling the SSH login is key to effective administration.

What is the basic SSH login command?

The standard command to connect securely to a remote server is:

ssh username@hostname_or_ip

• ssh: initiates the secure connection.
  
• username: your user account on the remote machine.
  
• hostname_or_ip: the server’s IP address or hostname.
  

Can you give an example?

Sure! If your username is axel and your server’s IP is 192.168.0.0, the command would be:

ssh [email protected]

Using Ubuntu SSH Command

In case you are using Ubuntu, the Ubuntu SSH command is not different from any other Linux distribution because it utilizes OpenSSH. Just open your terminal and use the same basic syntax. However, if SSH isn’t installed by default on your system, you can set it up with:

sudo apt update</code>

sudo apt install openssh-client

To check if the ssh command is working:

ssh -V

This will display the version of the SSH client installed on your machine.

Specifying a Port (If Different Than Default)

By default, SSH uses port 22. But if your server is configured to use a different port (for added security), you’ll need to specify it like this:

ssh -p 2222 username@hostname_or_ip

Just replace 2222 with your actual port number.

Best Practices for SSH Login

Here are a few tips to help keep your SSH logins secure and efficient:

1. Use SSH Keys Instead of Passwords

SSH key authentication is a more secure alternative to passwords. First, generate a key pair:

ssh-keygen

Then, copy your public key to the remote server:

ssh-copy-id username@hostname_or_ip

Once done, you can log in without entering your password each time:

ssh username@hostname_or_ip

2. Disable Root Login

Logging in directly as root can be risky. Instead, use a regular user account and then switch to root using sudo after logging in.

3. Keep SSH Updated

Always ensure that your SSH client and server are up to date to avoid vulnerabilities.

4. Use a Config File for Multiple Servers

If you access multiple servers often, create a config file in ~/.ssh/config to simplify logins:

<pre>

Host myserver

    HostName 192.168.0.0

    User axel

    Port 22

</pre>

Now, you can log in with:

ssh myserver

Troubleshooting SSH Connection Issues

Even if you’ve got everything correctly set up, you might still have problems when trying to SSH connect to a server. Panic not—most SSH connection problems can be rectified with a simple set of checks. This section walks you through common problems and how to resolve them, especially if you’re trying to establish SSH remote access.

1. Verify the SSH Service is Running

If your connection is being refused or timing out, first attempt to determine if the SSH server is up and running on the remote side. On Ubuntu, try the following command:

sudo systemctl status ssh

If it’s inactive, start it with:

sudo systemctl start ssh

Also, make sure SSH is enabled to start automatically:

sudo systemctl enable ssh

2. Check the Server’s IP and Port

Double verify that you are connecting to the correct IP address. In case you are behind a router, reference the local access internal IP or remote access public IP. If the server’s port number is non-standard (non-22), append it to the SSH command:

ssh user@your-server-ip -p your-port

Using the wrong IP or port is one of the most common causes of ssh connection errors.

3. Confirm Firewall and Port Forwarding Settings

A firewall or missing port forwarding rule can block SSH connections. On the server, check firewall rules using UFW (Uncomplicated Firewall) on Ubuntu:

sudo ufw status

Allow SSH through the firewall with:

sudo ufw allow ssh

If you are trying to use ssh remote access to a home computer, ensure that port 22 (or your other port) is correctly forwarded in the settings of your router.

4. Inspect the SSH Client Output

Add the -v (verbose) flag to your SSH command to get detailed error messages:

ssh -v user@your-server-ip

This response can help you determine the exact issue—whether a key mismatch, timeout, or connection refusal.

5. Check SSH Key Permissions

If you’re using SSH keys, make sure your private key permissions are secure:

chmod 600 ~/.ssh/id_rsa

If the permissions are too open, SSH might reject the key for security reasons.

6. Reboot as a Last Resort

If everything looks correct but the ssh connect still fails, try rebooting both the server and the client machines. Sometimes network services hang and can be fixed with a restart.

Using SSH for Remote Server Management

What is available through SSH when I administer a server?

SSH makes it possible to remotely control your server. You can install patches, change settings, and check how the server is doing — all from typed commands, without needing to be physically next to the computer.

Why should server management be done with SSH?

SSH is easy to use to manage your server remotely from anywhere you are connected to the internet. It’s great for developers, IT personnel, or anyone with a home or cloud server since you do not need to physically be at the server to debug or make changes.
