Originally created by @jacobrastad on GitHub (Jul 14, 2022).

Windows Terminal version

1.13.11432.0

Windows build number

10.0.22000.0

Other Software

Using ssh.exe

ssh.exe -V
OpenSSH_for_Windows_8.1p1, LibreSSL 3.0.2

Steps to reproduce

  1. Login/try to login with SSH on any remote host that accepts ssh connections. Then exit that.
  2. Run ping 8.8.8.8 -t
  3. Try to exit with ctrl+c

Update
The issue only appears if the ssh-session ends with some sort of error (like pressing ctrl+c when trying to connect). If I connect successfully and exits the ssh-session with exit command. Everything works as normal.

Expected Behavior

The ping-action should stop

Actual Behavior

Nothing happens, the continuous ping keeps going.

Tried ctrl+break which prints out a new empty line briefly. But it doesn't exit the running operation and the pingin keeps going.

Other info

Other possibly related issues

Which ssh are you using? ssh.exe that ships with Windows? ssh from a WSL distro? Or some other ssh? And which version of ssh/?

Does the same thing happen in a vintage console window (conhost.exe)?

@zadjii-msft I've updated the description with the info

ssh.exe -V
OpenSSH_for_Windows_8.1p1, LibreSSL 3.0.2

No issue using conhost.exe , there it works as expected

This looks a bit like

but

scares me, for sure.

Does this work in a Command Prompt tab, in the Terminal? Or the inverse, if you run powershell.exe in the vintage console, does this work there as well? (I'm just trying to work out the matrix of {conhost, Terminal}x{cmd.exe, powershell.exe}

Running a cmd tab in the Terminal works as expected.

Starting a vanilla cmd and then running powershell in that produces the same issue.

After a bit more testing, the issue only appears if I exit the ssh-session with ctrl+c.

I.e if I

  1. Run ssh and connect successfully
  2. Exits the session by typing exit

Then everything works as normal. But if I get any error trying to connect, misstyping the password causing the session to terminate or pressing ctrl+c, then the issue appears.

Okay great, thanks. All that would have me think that this is, in fact, https://github.com/PowerShell/Win32-OpenSSH/issues/1699, so I'm gonna close this to track the downstream issue. Thanks!
