Unable to ssh from the VSCode terminal when on Ethernet. #234389

Open holland11 opened 3 days ago

holland11 commented 3 days ago

Does this issue occur when all extensions are disabled?: Yes

Steps to Reproduce:

  1. Open a vscode window.
  2. Open the vscode terminal.
  3. Be connected to the internet via Ethernet.
  4. Run ssh <user>@<hostname> with a valid ssh user+hostname.
  5. Watch as it fails with ssh: connect to host <hostname> port 22: Undefined error: 0
  6. Unplug the Ethernet cable and connect to WiFi.
  7. Re-run the ssh command.
  8. Watch as it succeeds.

I'd be surprised if other people can reproduce this. Other people on my team running the same vscode version as me do not have the same issue. But I have no idea how to resolve it.

This extends to my remote-ssh vscode windows as well. They fail to connect until I unplug my ethernet cable.

I've tried updating my vscode. I've tried deleting my vscode and reinstalling a new one. I've tried deleting my ~/Library/Application Support/Code. I've tried disabling all my extensions. I've tried updating my OS. I've tried using bash instead of zsh in my vscode terminal.

The ssh command works flawlessly on ethernet through my macOS terminal. It's only in the vscode terminal that it fails.

Here is the -v output of the ssh command on Ethernet:

> ssh -v <username>@<hostname>

Your message text describes the first transcript as being from the WiFi case and the second from the Ethernet case. I assume you mistyped, right?

Yes, thanks for catching that. Sorry for the mixup.
