Re: simulate connection with netcat

Jake,

    For non technical users you can use ssh as a CA, you can create to 
each user a public key inside a USB Pendrive and them configure their 
ssh clients (like a portable putty, and so) with that certificate (key). 
This way they can authenticate to your server.
