To connect to an EC2 instance using SSH, follow these steps:
<ol>
<li>Ensure SSH Key File Permissions:
<ul>
<li>When you create an EC2 instance, AWS gives you a private key file (<code>.pem</code>). Download it and keep it secure.
</li>
<li>Change its permissions so only you can read it:
<pre><code class="lang-bash"> chmod 400 your-key.pem
</code></pre>
</li>
</ul>
</li>
<li>Find the Public DNS or IP of the Instance:
<ul>
<li>Go to the AWS EC2 Console &gt; Instances.
</li>
<li>Locate your instance and copy its Public DNS or Public IP.
</li>
</ul>
</li>
<li>Connect Using SSH:
<ul>
<li>Use the SSH command to connect to the instance. Replace <code>your-key.pem</code> with your key file, and <code>ec2-user@your-public-dns</code> with your instance’s username and DNS/IP.
</li>
<li>Example:
<pre><code class="lang-bash"> ssh -i your-key.pem ec2-user@your-public-dns
</code></pre>
</li>
<li>Common usernames for EC2 instances:
<ul>
<li>Amazon Linux: <code>ec2-user</code>
</li>
<li>Ubuntu: <code>ubuntu</code>
</li>
<li>CentOS: <code>centos</code>
</li>
<li>RHEL: <code>ec2-user</code>
</li>
<li>SUSE: <code>ec2-user</code>
</li>
</ul>
</li>
</ul>
</li>
<li>Security Group:
<ul>
<li>Ensure the EC2 instance’s Security Group allows inbound SSH (port 22) from your IP address.</li>
</ul>
</li>
<li>Exit: If we want to remove connection to the instance, just type exit
</li>
</ol>
Once these steps are completed, the SSH session should connect you directly to the EC2 instance. "Thank you for reading! I hope this blog sparked new ideas and insights.

To connect to an EC2 instance using SSH, follow these steps:

1. **Ensure SSH Key File Permissions**:
    
    * When you create an EC2 instance, AWS gives you a private key file (`.pem`). Download it and keep it secure.
        
    * Change its permissions so only you can read it:
        
        ```bash
        chmod 400 your-key.pem
        ```
        
2. **Find the Public DNS or IP of the Instance**:
    
    * Go to the **AWS EC2 Console** &gt; **Instances**.
        
    * Locate your instance and copy its **Public DNS** or **Public IP**.
        
3. **Connect Using SSH**:
    
    * Use the SSH command to connect to the instance. Replace `your-key.pem` with your key file, and `ec2-user@your-public-dns` with your instance’s username and DNS/IP.
        
    * Example:
        
        ```bash
        ssh -i your-key.pem ec2-user@your-public-dns
        ```
        
    * Common usernames for EC2 instances:
        
        * **Amazon Linux**: `ec2-user`
            
        * **Ubuntu**: `ubuntu`
            
        * **CentOS**: `centos`
            
        * **RHEL**: `ec2-user`
            
        * **SUSE**: `ec2-user`
            
4. **Security Group**:
    
    * Ensure the EC2 instance’s **Security Group** allows inbound SSH (port 22) from your IP address.
        
5. Exit: If we want to remove connection to the instance, just type exit
    

Once these steps are completed, the SSH session should connect you directly to the EC2 instance.
