New Post: A first chance exception of type 'Renci.SshNet.Common.SshConnectionException

Hi

I'm trying to access and give orders to a Sonicwall Firewall with the SSh.net lib in Visual studio 2012 in C#. I would like to give a simple SSH Order such as" ping 127.0.0.1 "and get the result as an output in to a textbox of a Winforms Application.

Remote System:
firmware-version "SonicOS Enhanced 6.1.1.9-30n"
model "Sonicwall NSA 3600"
My operating System:
Win 8.1
64 bit
.net framework 4

Transfer is just over LAN.


Output in Visual Studio2012 with SShConnectionException:
