Launch pwsh and -

    $RemoteHostNameOrIP = "zerotesting5.zero.lab"
    $SSHUserName = "zeroadmin@zero"
    $LocalPortForSSHTunnel = 5998
    $RemoteSSHPort = 22

    putty -ssh $RemoteHostNameOrIP -l $SSHUserName -L $LocalPortForSSHTunnel`:$RemoteHostNameOrIP`:$RemoteSSHPort

The above will launch a putty window where you'll have to enter your password, unless you have a key loaded in pageant. If you don't have pageant, but have a .ppk key available on your filesystem, you can do:


    putty -ssh $RemoteHostNameOrIP -l $SSHUserName -i $SSHKeyPath -L $LocalPortForSSHTunnel`:$RemoteHostNameOrIP`:$RemoteSSHPort


Create a New PSSession -

    New-PSSession -HostName localhost:5998

If you don't have an ssh key loaded into the OpenSSH-Win64 ssh-agent service (which is completely separate from putty), you'll get a password prompt:

    zeroadmin@ZERO@localhost's password:

    Id Name            Transport ComputerName    ComputerType    State         ConfigurationName     Availability
    -- ----            --------- ------------    ------------    -----         -----------------     ------------
    3 Runspace2       SSH       localhost       RemoteMachine   Opened        DefaultShell             Available

Then test the PSSession to make sure you're on your Remote Host:

    PS C:\Users\zeroadmin> Invoke-Command -Session $(Get-PSSession -Id 3) -ScriptBlock {$env:ComputerName}
    ZEROTESTING5

Cool!
