How do I obtain the CoC VPN client?


The CoC VPN has been migrated to use campus VPN services.  CoC faculty, grad students, and staff should use the instructions below. All others should follow the standard OIT VPN instructions.

Installing the AnyConnect Client

  • Point your web browser to the following URL:

  • You will be asked to log in with your GT account and password.  Do so and then click Continue.
  • At this point, the automatic installer will begin.  As it progresses, you may receive prompts to allow or grant permission.  Please allow or grant the needed permission.
    • If the automatic installer fails, you'll be given a link to download the manual installer.  Additional information on that is available below under Troubleshooting.
  • When the install is complete, the VPN client should automatically start with the correct server name prefilled.  If it does not, launch the Cisco AnyConnect client.  If the server name is not filled in, use, and click Connect.
  • You should now be prompted for your username and password.  Use your GT account and password.

After this, when you want to open your VPN connection again, open the Cisco AnyConnect VPN Client application and use the Connect button. You only need to do the web install step once.


In some cases, the automated installer will fail.  When that happens, a link will be provided to download a manual installer.  Users should click that and follow the install routine.  At the end, users will need to input in the client.  For more detailed instructions, OIT also has step-by-step instructions at  If following those instructions, users will need to substitute in all locations where it says to enter

Built-in Clients

Note:  Effective March 1, 2017, users enrolled in Duo must use two-factor authentication (2FA) with their VPN client.  At the time of this writing, the built-in clients listed below do not support 2FA.  Until such time as they do, Duo users should use the Cisco AnyConnect client for VPN access.  Additional information can be found here:  Again, If following those instructions, users will need to substitute in all locations where it says to enter

Linux Built-In VPN Client

These instructions were developed using the built-in VPN client in Debian 8.0 with xfce4. The instructions should still be relevant for other Debian based systems (such as Ubuntu) though the interface may differ depending on your desktop environment. For other environments (e.g. KDE or Gnome) or other Linux distributions, consult their documentation for installing packages. The rest should apply cross platform.

  1. You will need to first install the following packages to graphically configure the vpn. Open your default terminal emulator and enter (if using Ubuntu/Debian):

         sudo apt-get update

       sudo apt-get install network-manager-vpnc network-manager-vpnc-gnome

  1. Open your Network Connections window, likely accessible by right clicking the wi-fi/lan icon in your tray.
  2. Click the Add button, select the dropdown menu and scroll down to the VPN heading.
  3. Select the option for Cisco Compatible VPN (vpnc). If this is not visible, try restarting your system and come back to this step.
  4. Press Create and fill out the information in the window using the following values:

    Connection Name: <appropriate name>
    User Name: Use your GT account
    Password: Use your GT password (by default, this field will be grayed out. Select Saved from the dropdown next to the field to save the password for the future)
    Group name: gatech
    Group password: vpn4tech (again, by default the field is grayed. Select Saved in order to keep the password for the future)

  5. Then click Save.

Whenever you wish to connect to the VPN, left-click on the wi-fi/lan icon and select VPN Connections from the pop-up. Find the name you gave the connection, and select it. You should get a success message indicating that you are connected.
