Develop your code with [VS code remotely via a ssh connection](https://code.visualstudio.com/docs/remote/ssh).

Questions to [David Rotermund](mailto:davrot@uni-bremen.de)

## Installation

We need to install the Remote ssh extension

and these one too:

However, the second one should be installed automatically. 

## Configuration

Now you can enter your user and computer name / ip address of the ssh target:

It asks where to store the information (i.e. ssh key). Select the one in your home directory:

Now we can review the settings by clicking on "Open Config":

Or later by clicking here

and then here

In the moment my configuration looks like:

```python
Host gate1
  HostName gate1
  User sshtest
```

Typical options:

** HostName gate1: Can the the name or the IP of your ssh target
** User sshtest : Well, here you need to put your user name in.
** ForwardX11 yes : Allows you to view graphical from the other side
** Port 22 : This is the default port for the ssh connection. This can be also something else.
** XAuthLocation C:\Progra~1/VcXSrv/xauth.exe : In the case of a Windows 10/11, you need a X Window Server if you need to stream graphical windows to your local machine. Under Linux this is typically included and can be ignored. Under Windows you need a X Server. I tested the [VcXsrv Windows X Server](https://sourceforge.net/projects/vcxsrv/) sucessfully. 

Notes about the Windows 10/11 X Window Server: Last time I tested it, I had to add two Windows environment variables (you find the button "Environment Variables..." under system properties). Add under the User Variable section (The upper box under Environment Variables)

**DISPLAY**

with

127.0.0.1:0.0

and 

**TMPDIR** 

will it with the value of variable TMP

Also also the X Server needs to run. Means you have to start it if you want to use it... I used Multi Window Mode.
