Remote SSH forwards all ports

[rijenkii]

Issue Type: Bug

After a recent update VSCode started forwarding all ports that are opened on the remote machine by the user that is running the server -- before it just forwarded the ports that I have opened through the built-in terminal.
That in itself is not a much of a problem, until I try to connect to localhost -- then:

• VSCode forwards all opened ports;
• notices that some new ports have just opened (the ones that it just forwarded);
• forwards them;
• notices new opened ports;
• forwards them

ad infinitum.

@rijenkii could you share a screenshot of the Ports view (by default it's in the Remote Explorer activity in the sidebar)? I want to make sure I understand what you're describing.

@rijenkii I'm not able to reproduce this issue.

until I try to connect to localhost

What exactly are you doing to connect to localhost?

I tried to repro with the simple Microsoft/vscode-remote-try-node sample repo. My steps:

1. Connect to an SSH remote
2. Run node server.js, which runs a server listening on 3000
3. See that 3000 is auto forwarded
4. Open localhost:3000 in the browser

I have just reproduced this on a fresh install of Debian 10 with a fresh installed VSCode downloaded from code.visualstudio.com

Thanks, that clarifies things. I can repro.
