Steps to reproduce
- Set up PowerShell SSH remoting as both client and host on a Windows or Linux machine
- Establish that remoting is working back to the same machine
Enter-PSSession -hostname LocalComputerName -userName User
- Delete and recreate the host keys
On Windows go to where Win32-OpenSSH is installed and delete all "ssh_host_key*" files
Then create new files by running ssh-keygen.exe -A
- Try to create a new remote session
Enter-PSSession -hostname LocalComputerName -userName User
Expected behavior
Get complete SSH host key revocation error message
The entire SSH error message should be
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:Etb4yw1QyVJnP4eGKdvOG/xPy9F5rKEw+Xk02wXmJGU.
Please contact your system administrator.
Add correct host key in C:\\Users\\UserName/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in C:\\Users\\UserName/.ssh/known_hosts:1
ECDSA host key for LocalComputerName has changed and you have requested strict checking.
Host key verification failed.
