I have a remote setup with an intervening bastion machine, a.k.a., a "jump host". I use a ProxyCommand in my ssh_config file to allow the Remote (SSH) extension to sail right through. But of course, the ssh2 process being launched by remote-x11 does not take its cues from the ssh_config file and the connection to the target machine fails, even with a manually specified host. That host is just not accessible without going through the bastion machine.

Any chance you can support bastion hosts? They're not that uncommon. ssh2 does have a connection hopping solution here: https://github.com/mscdex/ssh2/issues/764. Also consider the https://github.com/Stocard/node-ssh-forward library that wraps the ssh2 jump host functionality reasonably neatly.

I could attempt to support it, but I don't have a setup like that readily available to test against. (I also have other things I'd rather spend me free time on than this extension at the moment.) I'll gladly accept a PR for it though.

I did find a library for parsing ssh_config, though I didn't find anything that would automatically make ssh2 honor ssh_config. I'll make another issue to see if I can at least read the settings I do support from it though.

I'm unlikely to get to it either, because of other obligations.

I'll point out that you don't really need a bastion set up to test. It's basically hopping from any host with an sshd to another host with an sshd running. Even two ports on the same machine.

@maxrpi Try https://github.com/joelspadin/vscode-remote-x11/pull/34, let me know if it works for your use case.

Hi! Thanks for the excellent extension. It made my life a lot easier. Would you like to restart work on this issue/associated PR. I have a setup that can be used for testing; and having this (proxy jump capability) would be great :)

Have you tested whether jump hosts work with the official x11 forwarding support yet?

Since Microsoft added support for SSH forwarding to their Remote SSH extension, I do not plan to do any more work on the SSH part of this extension.

It worked, our company switched to 2-factor and broke any chance of this working the day after I submitted a PR, lol. But for a traditional situation I think the PR comments were valid and this shouldn't be far from a valid solution.
