Copying VSCode Server to Host with SCP

Greetings, Dev! In this article, we will discuss a simple method to copy your VSCode server to your host machine using SCP. It’s an essential skill to have, especially if you’re a developer who uses remote servers or virtual machines to work on projects. The process may seem daunting, but with these 20 consecutive headings, we hope to make it much easier to understand.

What is VSCode Server?

Before we proceed, let’s make sure we’re on the same page about VSCode Server. VSCode Server is essentially the server component of the VSCode editor that provides a browser-based version of the editor. It enables you to run VSCode on a remote machine, and you can access it from your local machine through a web browser. It essentially allows you to edit code on a server without having to install your code editor on that server.

How Does VSCode Server Work?

When you run the VSCode Server, it starts a local webserver that listens on an IP address and port that you specify, typically on port 8080. You can then access the VSCode Server instance using a web browser. The editor client is downloaded from the server, and you can start editing your code right in your browser.

One advantage of using VSCode Server is that it’s lightweight and fast, making it perfect for remote development. That way, you don’t have to worry about having a bulky editor installed on multiple machines or servers.

Why Copy VSCode Server to Host Machine?

Running VSCode Server on a remote machine or virtual machine is great, but you may want to run it locally for various reasons. For instance, you may want to make changes to the server configuration files or use plugins that are not available on the remote machine. That’s where copying VSCode Server to your host machine comes in handy.

What is SCP?

SCP, or Secure Copy Protocol, is a simple and secure way to copy files between computers using the command line. It’s part of the OpenSSH suite of tools and is typically used for copying files to and from remote servers.

Step-by-Step Guide: Copying VSCode Server to Host Machine with SCP

Step 1: Start VSCode Server

The first step is to start the VSCode Server on the remote machine. You can do this by running the following command:

ssh username@remotehost -L 8080:localhost:8080 "code-server --auth none"

Replace ‘username’ with your username on the remote host and ‘remotehost’ with the name or IP of the remote host.

Step 2: Check VSCode Server Status

Once you have started the server, you should see the following message:

INFOProxying code-server to 127.0.0.1:8080

This message indicates that the server is running and is listening on port 8080 for incoming connections.

Step 3: Create a Temporary Directory

You will need to create a temporary directory on the remote machine to hold the VSCode Server files that you will copy to your host machine. You can do this by running the following command:

mkdir /tmp/code-server

This command will create a directory called ‘code-server’ in the temporary directory ‘/tmp’.

Step 4: Copy VSCode Server Files to Temporary Directory

Next, you need to copy the VSCode Server files to the temporary directory that you just created. You can do this by running the following command:

scp -r username@remotehost:/usr/lib/code-server/* /tmp/code-server/

This command will copy all the files in the ‘/usr/lib/code-server/’ directory on the remote host to the ‘/tmp/code-server/’ directory on the remote machine.

Step 5: Compress Temporary Directory

Once you have copied the files to the temporary directory, you need to compress them into a single file that you can transfer to your host machine. You can do this by running the following command:

tar -czvf code-server.tar.gz /tmp/code-server

This command will create a file called ‘code-server.tar.gz’ in the current directory that contains all the files in the ‘/tmp/code-server/’ directory.

Step 6: Copy Compressed File to Host Machine

Now that you have compressed the files, you can copy the ‘code-server.tar.gz’ file to your host machine using SCP. You can do this by running the following command:

scp username@remotehost:~/code-server.tar.gz .

This command will copy the ‘code-server.tar.gz’ file from the remote machine to your local machine.

Step 7: Extract Files on Host Machine

The final step is to extract the files from the compressed file on your host machine. You can do this by running the following command:

tar -xzvf code-server.tar.gz

This command will extract all the files from the ‘code-server.tar.gz’ file to a directory called ‘code-server’ in the current directory.

Frequently Asked Questions

What is the Default Port for VSCode Server?

The default port for VSCode Server is 8080. However, you can specify a different port when you start the server.

How Do I Access VSCode Server from My Browser?

You can access VSCode Server from your browser by navigating to http://localhost:8080. If you specified a different port when starting the server, replace ‘8080’ with the port number you specified.

Can I Use SCP to Copy VSCode Server to Multiple Host Machines?

Yes, you can use SCP to copy VSCode Server to multiple host machines. Simply repeat the steps outlined in this article for each host machine that you want to copy the server to.

Can I Use SSH Keys to Authenticate SCP?

Yes, you can use SSH keys to authenticate SCP. To do this, you need to set up SSH keys on both the remote host and your local machine, and then use the -i flag to specify the path to your SSH private key when you run the SCP command.

What Happens to VSCode Server on the Remote Machine After I Copy It?

Copying VSCode Server to your host machine does not delete it from the remote machine. The server will continue to run as long as the SSH connection is active. If you want to stop the server, you need to log out of the remote machine or terminate the SSH connection.
