Can you turn on server-side logging and provide the sshd.log from that after a single connection attempt?

Use LOCAL0 / DEBUG3 in sshd_config as described in https://github.com/PowerShell/Win32-OpenSSH/wiki/Troubleshooting-Steps

Here's the log, one attempt only ;)

[NoMoreFood]

On the server in a command prompt, can you verify the following doesn't produce any error messages:

C:\Windows\system32\conhost.exe --headless --width 80 --height 24 --signal 0x214 -- "c:\windows\system32\cmd.exe"

[HealisticEngineer]

No error on the command prompt, no output at all.

[DHowett-MSFT]

A bit of psychic debugging here:

Are you using the 32-bit version or the 64-bit version of Win32-OpenSSH? If you're using the 32-bit version on a 64-bit OS, I'm willing to bet that C:\Windows\System32\conhost.exe is being redirected to C:\Windows\SysWOW64\conhost.exe, which doesn't exist.

If so, there're two fixes, one short term and one long term:

• Short-term: use 64-bit win32-openssh(-win64)
• Long-term: When spawning a PTY, win32-openssh should either use our CreatePseudoConsole API or disable Wow64 filesystem redirection when spawning conhost.

Side note: we had this exact problem when we implemented CreatePseudoConsole and friends, and I ended up fixing it ;)

[DHowett-MSFT]

(and for the engineer who has to fix this: please switch to CreatePseudoConsole. In the absence of time to do that, however, the offending block of code is here and you'll have to use Wow64DisableWow64FsRedirection immediately before (but only on WOW64 builds) and Wow64RevertWow64FsRedirection immediately after creating the process.)

[HealisticEngineer]

Thanks for the pointer I've switched the 32-bit for the 64-bit package and all works.
Both password and public key now work fine.

[DHowett-MSFT]

@HealisticEngineer Excellent! I've not been deputized to do issue management on this repository, so would you mind renaming the bug to ConPTY fails to launch in WoW64 due to filesystem redirection?

/cc @manojampalam

Thanks!

[HealisticEngineer]

Done ;)

[NoMoreFood]

@bagajjal Any particular reason by CreatePseudoConsole() wasn't used as @DHowett-MSFT suggests? Obviously disabling file system redirection is easy, but curious why the function wasn't used.

[DHowett-MSFT]

@NoMoreFood We worked with the win32-openssh team to light up pseudoconsole support before our APIs were ready with the public release of RS5. That's all :)

[DHowett-MSFT]

@bagajjal (since this is still an actual issue, would you mind reopening it? thanks!)
