I have a work PC with Windows 11, where I am logged in with a work account, and a Windows 11 work laptop. I would like to connect to the PC via OpenSSH to deploy some code for local testing.
So, I set up OpenSSH on the PC by following this support article.
However, when I try to connect to the PC from the laptop with ssh domain\[email protected], OpenSSH first asks me whether I trust the machine. Then, when I confirm, the command line blocks a few seconds and finally prints:
Connection reset by 10.x.y.z port 22
OpenSSH within WSL shows the same behavior. Same happens when I use an SSH key to connect.
When I leave out the user part and only connect with ssh 10.x.y.z, it asks me for the password of user, but rejects it immediately when I enter it correctly.
To confirm whether I set up the host correctly, I tried the following:
PS C:\Users\user> whoami
domain\user
PS C:\Users\user> Get-Service ssh-agent
Status Name DisplayName
------ ---- -----------
Running ssh-agent OpenSSH Authentication Agent
