New Post: How access SonicWALL

I'm try access an TZ 205 like this:
New-SshSession -ComputerName 192.168.168.168 -port 8022 -Username admin ...

I receive this:
Successfully connected to 192.168.168.168

So I try this:
Invoke-SshCommand -InvokeOnAll -Command 'show interface X2'
and I receive this:
Invoke-SshCommand : Exception calling "RunCommand" with "1" argument(s): "An established connection was aborted by the server."

Someone executed command at SonicWALL already?
