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

## 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.
|
|
|
|
## Using it
|
|
|
|
Select the connection you want:
|
|
|
|
|
|
|
|
Enter your password:
|
|
|
|
|
|
|
|
Be connected:
|
|
|
|
|
|
|
|
The first time you make a connection to a system, you need to check if all extensions are there. Typically they are not. Just scroll through the list of "installed" extensions and click on install... again...
|
|
|
|
|
|
|
|
Side note: You can use the terminal under VS code as a terminal running on the ssh target computer. Or in other word: You can use the terminal to create directories via mkdir and move files around. Or even more complicated programs:
|
|
|
|
|
|
|
|
## Exchanging files between computers
|
|
|
|
There are many options to exchange files via ssh between computers. However [filezilla **client**](https://filezilla-project.org/download.php?type=client)!!! is a nice too that is available for Windows and Linux alike. Many Linux distributions have Filezilla already in their package repositories.
|
|
|
|
First time you start it, you want to got into the connection settings:
|
|
|
|
|
|
|
|
Create a new connection and name the parameter setting accordingly:
|
|
|
|
|
|
|
|
Now you need to put in the information about your ssh connection:
|
|
|
|
|
|
|
|
* Switch to SFTP
|
|
* Enter the hostname or ip
|
|
* Enter the port (default is 22)
|
|
* Enter your user name
|
|
* Add you password or better set to ask for password
|
|
|
|
Press OK to save the information.
|
|
|
|
Now the configured connection is available:
|
|
|
|
|
|
|
|
It will ask you for your password:
|
|
|
|
|
|
|
|
And the first time you connect to the ssh server (or in the case the server was replaced by the admin) you will get this message:
|
|
|
|
|
|
|
|
After OK you can shove files / directories from one side to the other.
