![]() All SSH events are available in a separate section Application and Services Logs > OpenSSH > Operational.įor example, the screenshot shows an example of an event with a successful connection to the computer via SSH. On Windows 11, SSH logs can be viewed using the Event Viewer console (eventvwr.msc). In previous versions of OpenSSH on Windows, all sshd service logs were written to the text file C:\ProgramData\ssh\logs\sshd.log by default. The allow and deny rules of sshd are processed in the following order: DenyUsers, AllowUsers, DenyGroups, and AllowGroups.Īfter making changes to the sshd_config file, you need to restart the sshd service: Get-Service sshd| Restart-Service –force AllowGroups theitbros\ssh_allow - only allow users from theitbtos\ssh_allow connect hostю.DenyUsers theitbros\* - prevent all users from theitbros domain to connect host using sshж.DenyUsers - blocks connections to username jbrown from 192.168.1.15 hostsж. ![]() Using the directives AllowGroups, AllowUsers, DenyGroups, DenyUsers, you can specify users and groups who are allowed or denied to connect to Windows via SSH: Here you can also specify a new TCP port (instead of the default TCP 22 port) on which the SSHD will accept connections. Use the command: ssh -l can configure various OpenSSH server settings in Windows using the %programdata%\ssh\ sshd_config configuration file.įor example, you can disable password authentication and leave only key-based auth with: Then, the contents of the id_rsa.pub file must be copied to the c:\users\admin\.ssh\ authorized_keys file in Windows 10.Īfter that, you can connect from your Linux client to Windows 10 without a password. If you want to use key-based ssh authentication instead of password authentication, you need to generate a key using ssh-keygen on your client. ![]() From here, when connecting to Windows via SSH, you will immediately see PowerShell prompt instead of cmd.exe. Now, you change the default OpenSSH shell. To run the PowerShell.exe cli instead of cmd.exe shell when logging in via SSH on Windows 10, you need to run the following command in Windows 10 (under admin account): New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -PropertyType String -Force 192.168.1.90 is an IP address of your Windows 10 computer.Īfter that, a new Windows command prompt window will open in SSH session. To connect from Linux, use the command: ssh -p 22 the admin is a local Windows user under which you want to connect. Now you can connect to Windows 10 using any SSH client. Or you can add a firewall rule to allow SSH traffic using PowerShell: New-NetFirewallRule -Name sshd -DisplayName 'OpenSSH Server (sshd)' -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 22 You can open the port using netsh: netsh advfirewall firewall add rule name=”SSHD service” dir=in action=allow protocol=TCP localport=22 You also need to allow incoming connections to TCP port 22 in the Windows Defender Firewall. Set-Service -Name ‘ssh-agent’ -StartupType 'Automatic' Set-Service -Name sshd -StartupType 'Automatic' To start services and configure autostart for them, run the following commands: Start-Service sshd As you can see, both services are in a Stopped state and not added to the automatic startup list.
