I believe this is similar to: #1529

That ticket was closed saying Node doesn't support 32-bit architecture. But I think there is more nuance to it than that.

It appears to be running the following:
ssh -T -D [port] [user]@[host] bash

This always hangs to connect for me when connecting to 32-bit Linux servers. But if I connect with:
ssh [user]@[host]

It works. The problem seems to be the "-T" and the "bash" arguments. If I include either of them it fails but removing both works. The -D [port] argument doesn't seem to affect it.

So if it's possible, can Remote-SSH try removing these arguments on failure and trying again?

I have trouble connecting to an old Raspberry Pi 2 via VSCode. When logging in VSCode gives me an error message, Could not establish connection to "IP_ADDRESS": The remote host's architecture is not supported. On another Raspberry 2 it was possible to connect. I tried uname -m on the Raspberry and it tells me armv6l.

Is it possible that the RasPi with the working VSCode connection has a processor architecture with armv7l?

What can I do to get VSCode connected to my Raspberry 2?

I think the explanation is here #669

The whole Microsoft team unable to write a tiny portable C program for the remote side server, and require the full Node.js installed?
Why not to use generic GDB stub + the same generic SSH?

Extensions and much more run remotely with Remote - SSH. Fundamentally extensions are written in Node.js. Many of VS Code's built in features are written as extensions, so there is no workaround here. This is what sets it apart from using SSHFS or something along those lines.

As a result, we unfortunately we won't be able to meet this request.
