Security

All users must have SECURE passwords. Hackers regularly attempt to gain access to the cluster through users' accounts. We have adopted an additional security measure to protect our users:

In order to connect to stats.phys.uconn.edu, all users must first connect to a UConn computer and then ssh to stats.phys.uconn.edu. For anyone trying to access the cluster offsite and doesn't know a UConn computer to connect to, please contact your advisor.

You can also connect to Skybox and then use PuTTY from within Skybox to ssh to stats.phys.uconn.edu or you can use the UConn VPN http://remoteaccess.uconn.edu/vpn-overview/connect-via-vpn-client/
