Department VPN

The Computer Science Department VPN (Virtual Private Network) is a service provided by the Campus Division of Information Technology (DoIT).

The VPN service provides a secure connection between an untrusted or unknown network (at home, a hotel, coffee shop or other location including a campus location outside the Computer Sciences network) to the Computer Sciences Department networks so you can securely access Computer Sciences services. It can also be used to access unsupported/insecure computers on the Computer Sciences network that are isolated from the Internet.

Services that require use of the VPN include:

  • Instructional Linux VNC - Remote desktop access to Linux instructional computers for students (using the VNC protocol)
  • Remote Desktop - Remote desktop access to Windows workstations and remote desktop server (instructional Windows workstations are not available via Remote Desktop, students can use the remote desktop server)
  • Remote printing
  • Remote access to licensed software - To be implemented in the future
  • Other Computer Sciences services that require secure access and authentication (as needed)

More services are planned for the future.

Accessing the Computer Sciences Department VPN

This VPN service is provided for Faculty, Staff, and Students. If you have a Computer Sciences login you have access to the department VPN. Once you connect you need to authenticate using your Computer Sciences login name and password.

DoIT maintains documentation for installing and using the VPN software:

Connecting to the Computer Sciences VPN

Choose the Central Campus VPN server.

When you connect to the VPN you will be offered two Computer Sciences Department options which configure network routing differently:

COMP_SCI_SPLIT:

Only traffic for the campus network is routed via the VPN, all other Internet traffic is routed via your ISP ("split tunnelling"). This is the recommended configuration.

COMP_SCI_FULL:

All traffic is routed via Computer Science and then to the campus or internet ("full tunnelling"). This choice should only be used in special cases. If you are having routing problems to some sites when using the COMP_SCI_SPLIT configuration, try COMP_SCI_FULL.
