The SNS computers can be accessed remotely, from off-campus locations as well as from the IAS housing complex, by using ssh protocol 2 (secure shell). The SNS computers which allow remote ssh access are ssh1.sns.ias.edu and ssh2.sns.ias.edu. Alternatively, use the alias ssh.sns.ias.edu to connect to one system or the other.
A VPN (Virtual Private Network) service faciliates secure remote access to IAS computing resources for all users at IAS. The VPN can be accessed from any machine with an internet connection and a web browser, via https://vpn.ias.edu.
By logging into the VPN, you are attaching your computer to the IAS network, thereby facilitating access to certain services not otherwise available.
