Description

Is there an existing issue for this bug?
  • I have searched the existing open issues and found none that apply.
  • If I find any issue of interest that is related or closed, I will included a link to it in this issue.
Required Troubleshooting Steps
  • I have read and performed the troubleshooting steps
  • I have tried both values of the remote.SSH.useLocalServer setting
  • My issue was not covered in the Tips and Tricks linked from the Troubleshooting Wiki.
  • I will include a complete copy of my Remote - SSH logs by running Remote-SSH: Show Log in the command palette or from View > Output in the menu bar
[Optional] Diagnose with Copilot

I did not ask the @remote-ssh participant for help

In step 2 of the troubleshooting wiki, what was the result of running the generated SSH command verbatim outside of VS Code?

I did not try step 2 of the troubleshooting steps

Expected Behavior

connect success

Actual Behavior

Failed to parse remote port from server output

Steps To Reproduce

Using OpenSSH_for_Windows_9.5p1, LibreSSL 3.8.2
Remote side is openSUSE Tumbleweed

result of ssh.exe -T -D 52630 -F "C:\Users\yhryf\.ssh\config" 192.168.80.146 is is good

C:\Users\yhryf>"C:\Windows\System32\OpenSSH\ssh.exe" -T -D 52630 -F "C:\Users\yhryf\.ssh\config" 192.168.80.146 ls

I have also tried downgrade the Remote - SSH, and I found some different result

  • remote-ssh@0.109.0 can download and connect successfully, everything seems good
  • remote-ssh@0.110.0 cannot download but can connect to the server download by @0.109.0
  • remote-ssh@0.110.1 failed as the same as the latest version

I found that the struct of .vscode-server has been changed sinse 0.110.1 and use the .vscode-server/code-[commit] rather than use the .vscode-server/bin/[commit].
Dose it make some broken change?

Anything else?

Research direction

Start with the supplied Remote-SSH log and the handleInstallOutput entry point shown in extension.js, focusing on the empty listeningOn value after the server starts on openSUSE Tumbleweed. Reproduce the connection with the listed OpenSSH command and compare Remote-SSH versions; done means the remote port is parsed and the connection succeeds.
