If you normally have to use a smartcard to log in, you will need to have the appropriate smartcard drivers, reader, etc.Either your Windows desktop, or the JLABTS terminal server. You must know the name of the your Windows computer on site.On the off-site system, you must have a remote desktop client program, included with Windows.For older Windows systems, we suggest the PuTTy SSH and telnet client. Recently, Microsoft has begun providing a Secure Shell client (based on OpenSSH) on Windows 10 systems. On the off-site system, you must have a 'secure shell' or 'ssh' client that allows you to do tunneling.This technique can be used to connect to individual Windows desktops (if properly configured), or designated Windows terminal servers on site.
Since direct connections to internal JLab systems are not allowed from the internet, to make such a connection from offsite, you must use software (either VPN or ssh/PuTTY) that creates a secure connection or 'tunnel'. Windows 'Remote Desktop' or 'Terminal Services' is a feature available in modern Windows systems that allows you to login to a Windows computer over the network.
