Connect Linux to CU VPN

Connect to Cornell's VPN using Cisco AnyConnect software.

This article applies to: CU VPN


To use Cornell's Virtual Private Network (VPN) with campus networks and services, you must use Cisco AnyConnect VPN software. See the How to Install Cisco VPN Software page for instructions.

By July 15, 2021, Two-Step Login will be required for all users to authenticate to the CU VPN and all departmental VPNS. Using Two-Step Login allows you to better protect both your personal information and the university's services and data under your custodianship.

Connect to CU VPN with Two-Step Login

Duo Security provides documentation on how to log in to the Cisco AnyConnect client used with Cornell's VPN service. For more information, see Logging in with Cisco AnyConnect Client.

  1. At the command line (in a Terminal window), enter:
    /opt/cisco/anyconnect/bin/vpnui &
    or
    launch via Applications - Internet - Cisco AnyConnect Secure Mobility Client.
  2. In the AnyConnect window be sure that cuvpn.cuvpn.cornell.edu is selected in the Connect To box, then click Connect.


     
  3. In the Cisco AnyConnect window:
    • In the Group box, select Two-Step_Login. This will be required for all VPNs as of July 15, 2021, but you can use it any time.
    • In the User Name box, enter your Cornell NetID or GuestID.
      Note: If you are connecting to a departmental VPN, enter your NetID and the name of the departmental group, for example, pqs665@departmental_group_name.
    • In the Password box, enter your NetID password.
    • In the DUO Passcode (push/SMS/phone) box, type one of the following options to complete Two-Step Login:
    • Click Connect.
    • If you entered push or phone, complete the Two-Step Login process.
      You're now connected to CU VPN.
If you don't have access to the default device you use for Two-Step Login, you can use an alternate device. In Step 3 above, enter the method you use to complete Two-Step Login followed by a number, for example push2 or phone2. To see the devices you have set up and the numbers to use for each, go to Your Two-Step Login Devices and use the number in the Device Number column.
