I think everyone by now knows the remote plugin for vscode.

If not, you can install it here:


With the Remote - SSH extension installed, you will see a new Status bar item at the far left.


Handy features

Configuration file

If you log in to multiple remote servers or local virtual machines on a regular basis, there’s a better way to connect without having to remember all the usernames, addresses, and additional configuration options.

To use an SSH config file, click on the remote indicator to bring up the remote commands, choose Open Configuration File, and select the file that follows the path “Users/{yourusername}/.ssh/config”.


1# Read more about SSH config files:
2Host python-linux-vm
3 HostName <vm address>
4 User sana
5 IdentityFile ~/.ssh/id_python_vm
7Host node-vm
8 HostName <vm address>
9 User sana
10 Port 5522
11 IdentityFile ~/.ssh/id_node_vm

Once you’ve saved the config file, you’ll be able to see those hosts in the Remote Explorer



Sometimes you may need to connect from your desktop or laptop to a remote machine over your company’s Intranet or behind a firewall. In this case, you may be using an intermediate server or jump box. This kind of setup is useful if you are working within a secure system that is configured to only accept SSH connections from a fixed set of hosts.

To use a jump-box setup with the Remote - SSH extension, you can use the ProxyCommand config option. This configuration will open a background SSH connection to the jump box, and then connect via a private IP address to the target.

You can set the ProxyCommand config option in the SSH config file like this:

1# Jump box with public IP address
2Host jump-box
3 HostName
4 User sana
5 IdentityFile ~/.ssh/jumpbox
7# Target machine with private IP address
8Host target-box
9 HostName <IP address of target>
10 User sana
11 IdentityFile ~/.ssh/target
12 ProxyCommand ssh -q -W %h:%p jump-box
