Can't connect to Sepal with VSCode Remote SSH and Windows11/WSL2

[TmtStss]

I have a Windows 11 computer with a Windows Subsystem for Linux (WSL2). I use VS Code as code editor, and would like to connect to Sepal using the convenient Remote SSH extension. Here is the content of my C:/Users/my_username/.ssh/config file. I get a prompt asking for my password and then it tries to connect indefinitely or refuses connection.. I can access Sepal through ssh directly (e.g. for scp file transfer) without issue. I also tried implementing this popular fix, without success. So I wonder if the issue is not with Sepal.

why is the tested port 37779 ? I'm not sure it's exposed in SEPAL

[lpaolini]

VS Code Remote SSH extension sets up port forwarding when it connects to a remote. However, SEPAL ssh gateway doesn't support that, for now.

Thank you for the clarification. Is there a plan to support this feature in the future ? I don't know how many of the Sepal users use Sepal for dev purposes like me (hence how big is the incentive), but it would help a lot to have it (and alike, e.g. #251).

[lpaolini]

I agree it would be a nice feature. We will take your request into consideration.

@lpaolini: are there any plans concerning the implementation of this feature?
