Step 3: Configure MobaXterm for Your EC2 Connection

Now that you have the required information, it’s time to configure MobaXterm.

  1. Open MobaXterm: Start the MobaXterm application on your computer.
  2. Create a New Session:
  3. Click on the “Session” icon from the toolbar.

  4. Select the “SSH” option in the session settings window.

  5. Fill in the Session Details:

  6. Remote Host: Enter the Public DNS or Public IP address of your EC2 instance.
  7. Specify Username: In the “Specify username” field, enter ec2-user, ubuntu, or centos based on the Operating System of your EC2 instance.

  8. Load the Private Key: Under the “Advanced SSH settings” tab, check the option “Use private key” and browse to locate your .pem file.

  9. Adjust Additional Settings (Optional):

  10. You can customize the terminal settings, such as colors and fonts, in the “Settings” tab.

  11. To enable X11 forwarding, check the box if you plan to use graphical applications.

  12. Save and Connect:

  13. Optionally, click “Bookmark settings” to save your session for future use.

What are the prerequisites for connecting to an AWS EC2 instance using MobaXterm?

Before you can connect to your AWS EC2 instance via MobaXterm, you’ll need to have the necessary credentials. This includes the public DNS name or IP address of your EC2 instance, along with a private key file (PEM format) that corresponds to the key pair you selected when creating the instance. Make sure that the security group associated with your instance also allows inbound SSH traffic on port 22.

Additionally, ensure that you have installed MobaXterm correctly and configured your network settings to allow outbound SSH connections. Having a stable internet connection is also important to ensure a smooth experience when accessing your EC2 instance remotely.

How do I connect to my AWS EC2 instance using MobaXterm?

To connect to your AWS EC2 instance, launch MobaXterm and click on the “Session” button in the upper left corner of the interface. From the session selection dialogue, choose “SSH” as the session type. In the “Remote host” field, enter the public DNS name or IP address of your EC2 instance.

Next, specify the username for connection—this is usually “ec2-user” for Amazon Linux instances or “ubuntu” for Ubuntu instances. Don’t forget to select the option to use a private key for SSH connection and then browse to your PEM file location. After clicking “OK,” MobaXterm will attempt to establish the connection, allowing you to access your instance’s command line.

Can I transfer files between my local machine and the EC2 instance using MobaXterm?

Yes, MobaXterm facilitates file transfers between your local machine and your AWS EC2 instance seamlessly. When you connect to your EC2 instance using MobaXterm, the SFTP functionality automatically initializes in a split screen view. This allows you to drag and drop files between the remote environment and your local file system effortlessly.

You can also navigate through directories within the SFTP panel. To upload files, simply drag them from your local panel into the remote panel, and for downloads, drag files from the remote panel to your local one. This integration makes MobaXterm a powerful tool for managing files on your AWS EC2 instances without additional software.

What should I do if I cannot connect to my EC2 instance?

If you encounter difficulties connecting to your EC2 instance using MobaXterm, first ensure that your instance is running by checking the AWS Management Console. If the instance is indeed operational, double-check the security group settings to make sure that inbound SSH traffic on port 22 is allowed from your IP address. It’s also a good idea to confirm that you are using the correct public DNS or IP address and the associated user name.

Another potential issue may relate to your private key file. Ensure that the PEM file is not changed or renamed and that you have selected the correct one in MobaXterm. If you recently changed your instance’s private key or made any changes to its configuration, those updates might require reconnecting with the correct settings.

Is MobaXterm free to use, and are there limitations in the free version?

MobaXterm offers a free version that includes many useful features for both beginners and advanced users. The free edition allows you to create multiple sessions, use the integrated terminal, transfer files, and access various network tools like FTP and SSH. However, it may have limitations, such as a maximum of 12 tabs and restrictions on SSH gateways, which might not suit heavy users or professionals requiring advanced capabilities.

For users needing more robust features, MobaXterm also offers a professional edition that includes additional functionalities, priority support, and more complex session management capabilities. Keep in mind that the free version is still highly functional for most basic tasks and is ideal for typical personal or small business use.
