Powershell posh-ssh and cisco

Question

I am having some issues getting command to work with posh-ssh and Cisco gear.

Commands are pretty simple;

New-SSHSession -ComputerName 10.10.101.240 -Port 22

Will connect fine, and will give me an ID.

I then try

Invoke-SSHCommand -SessionId 0 -Command "show version"

but I always get

    Exception calling "EndExecute" with "1" argument(s): "An established connection was aborted by the server."
At C:\Program Files\WindowsPowerShell\Modules\Posh-SSH\2.0.2\Posh-SSH.psm1:266 char:25
+                         $Output = $_.cmd.EndExecute($_.Async)
+                         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : SshConnectionException

I have tried different hosts and different PCs. I can, however, use $sshsession.write() and $sshsession.read() and I can talk to the switch fine.

Can anyone point out what I am doing wrong here?
