- Username: The username you’ll use to log in to the server.
- Password: The corresponding password for the username.
- Port Number: The default port for SSH is
22, but if your server uses a different port, be sure to note that.
Connecting to Your Linux Server
Now that you have MobaXterm installed and the connection information prepared, follow these steps to connect to your Linux server successfully:
Launch MobaXterm
Open MobaXterm on your desktop or choose to run it as an administrator to ensure that you have the necessary privileges to run all features.
Step 1: Start a New Session
- Click on “Session” Button: In the MobaXterm window, locate and click on the “Session” button in the toolbar.
- Select SSH Option: In the session settings, choose the “SSH” option from the session types.
Step 2: Configure the Connection
In the SSH session configuration window:
- Remote Host: Input your server’s IP Address in the “Remote host” field.
- Specify Port Number: If you are using a non-standard port for SSH, enter it in the “Port” field.
- Username: Enter your username in the designated field.
Additional Configuration Options
MobaXterm allows you to personalize your connection settings further:
- Check “Use private key”: If you are using SSH key authentication instead of a password, you can specify your private key file here.
- Set Environment Settings: Adjust terminal settings, such as font size and colors, to your preferences.
Save Your Session (Optional)
If you plan to connect to this server frequently, you might consider saving the session settings:
- Session Name: Enter a name for the session in the “Bookmark Settings” field.
- Save Settings: Click on the “OK” button to save your configuration.
Step 3: Connect to Your Server
Once you’ve configured all the settings, click the “OK” button at the bottom of the SSH session window. You should see a terminal window that prompts you for your password (if you haven’t set up key-based authentication).
Step 4: Enter Your Password
Type your password in the terminal window and hit Enter. It’s important to note that when entering your password, you won’t see any visual feedback (like asterisks). Simply type it in and press Enter.
Navigating Your Linux Server with MobaXterm
After successfully logging in, you are presented with a command-line interface that allows you to interact with your Linux server. Here are some basic commands to get you started:
- ls: Lists the contents of the current directory.
- cd [directory]: Changes the directory to the specified folder.
Using the Embedded X11 Server
MobaXterm comes with an embedded X server, enabling you to run graphical applications on the remote server. Here’s how to do it:
- Confirm X11 Forwarding: Ensure that your SSH session has X11 forwarding enabled. To do this, check the “X11 forwarding” option while setting up your session.
- Run Graphical Applications: Once logged in, you can launch graphical applications by typing their names in the terminal. For example, typing
xclockwill show a graphical clock.
File Transfer Using MobaXterm
MobaXterm excels not just in connecting to remote servers but also in facilitating easy file transfers. You can use either the built-in SFTP file browser or drag-and-drop functionality.
Transferring Files via SFTP
When you connect to a Linux server using MobaXterm, an SFTP browser automatically opens in a split window. You can use this interface to manage your server files as follows:
- Navigate Local Files: On the left side, browse your local machine’s directories.
- Access Remote Files: The right side displays the directories on your Linux server.
- Drag and Drop: Simply drag files from one side to the other to initiate transfer.
Command-Line File Transfer
Alternatively, you can also use command-line tools such as scp for file transfer. For example:
bash
scp localfile.txt username@server_ip:/remote/directory/
Troubleshooting Common Connection Issues
Connecting to a Linux server through MobaXterm is generally a seamless process. However, here are common issues and their solutions:
1. Connection Refused Error
If you encounter a “connection refused” message, consider:
- Checking if the SSH service is running on the server.
- Verifying that you are using the correct IP address and port.
2. Authentication Failures
If you face issues with authentication:
- Ensure that you’re entering the correct username and password.
- Verify that SSH key authentication is set up properly if you’re using a key.
3. Slow Connection Speeds
If your connection is notably slow:
- Consider checking your internet connection.
- Run a traceroute to understand where the lag might be occurring.
