+## SSH into code-server on VS Code
+
+[![SSH](https://img.shields.io/badge/SSH-363636?style=for-the-badge&logo=GNU+Bash&logoColor=ffffff)](https://ohmyz.sh/) ![Terminal](https://img.shields.io/badge/Terminal-2E2E2E?style=for-the-badge&logo=Windows+Terminal&logoColor=ffffff) [![Visual Studio Code](https://img.shields.io/badge/Visual_Studio_Code-007ACC?style=for-the-badge&logo=Visual+Studio+Code&logoColor=ffffff)](vscode:extension/ms-vscode-remote.remote-ssh)
+
+ Follow these steps where code-server is running:
+  1. Get `OpenSSH-Server`, `wget`, and `unzip` before getting ngrok. Also, run `sudo apt update` so you get the latest versions.
+ ```bash
+ sudo apt update
+ sudo apt install wget unzip openssh-server
+ ```
+ 2. Start OpenSSH-Server and set the password of your computer. Eg. If you use a Railway deployment, the user is `coder` and so, the command to change the password would be `sudo passwd coder`.
+ ```bash
+ sudo service ssh start
+ sudo passwd {user} # replace user with your code-server user
+ ```
+

+
+ 1. Install [cloudflared](https://github.com/cloudflare/cloudflared#installing-cloudflared) on your local computer
+ 2. Then go to `~/.ssh/config` and add the following:
+ ```shell
+ Host *.trycloudflare.com
+ 	HostName %h
+ 	User root
+ 	Port 22
+ 	ProxyCommand "cloudflared location" access ssh --hostname %h
+ ```
+3. Run `cloudflared tunnel --url ssh://localhost:22` on the remote server
+
+ 3. Finally on Visual Studio Code, run `ssh coder@https://your-link.trycloudflare.com` or `ssh [email protected]`
+
+
+[![Ngrok](https://img.shields.io/badge/Ngrok-1F1E37?style=for-the-badge&logo=ngrok&logoColor=ffffff)](https://ngrok.com/)
+
+ 1. Make a new account for ngrok [here](https://dashboard.ngrok.com/login)
+
+ 4. Now, get the ngrok binary with `wget` and unzip it with `unzip`:
+ ```bash
+ wget "https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip"
+ unzip "ngrok-stable-linux-amd64.zip"
+ ```
+ 5. Then, go to [dashboard.ngrok.com](https://dashboard.ngrok.com) and go to the `Your Authtoken` section.
+ 6. Copy the Authtoken shown there.
+ 7. Now, go to the folder where you unzipped ngrok and store the Authtoken from the ngrok Dashboard.
+ ```bash
+ ./ngrok authtoken YOUR_AUTHTOKEN # replace YOUR_AUTHTOKEN with the ngrok authtoken.
+ ```
+ 8. Now, forward port 22, which is the SSH port with this command:
+ ```bash
+ ./ngrok tcp 22
+ ```
+ Now, you get a screen in the terminal like this:
+
+ ```output
+ ngrok by @inconshreveable(Ctrl+C to quit)
+
+ Session Status                online
+ Account                       {Your name} (Plan: Free)
+ Version                       2.3.40
+ Region                        United States (us)
+ Web Interface                 http://127.0.0.1:4040
+ Forwarding                    tcp://0.tcp.ngrok.io:19028 -> localhost:22
+ ```
+
+Copy the forwarded link `0.tcp.ngrok.io` and remember the port number `19028`. Type this on your local Visual Studio Code:
+
+ ```bash
+ ssh [email protected] -p 19028
+ ```
+ The port redirects you to the default SSH port 22, and you can then successfully connect to code-server by entering the password you set for the user.
