To connect with your Sandbox, you need a secure connection to our infrastructure. Following this guide you will be able to access your Sandbox through the Secure Shell (SSH) network protocol.
ssh <cloud_username>@<sandbox host>
That’s all :-)
cd \path\to\your\putty\folder
PUTTY.EXE -i id_rsa.ppk <cloud_username>@<sandbox_host>
That’s all :-)
