Go to Applications→ Internet→ Cisco AnyConnect Secure Mobility Client→ Cisco AnyConnect Secure Mobility Client to start the client. If the application does not start (the icon bounces for a bit and goes away), bring up a terminal emulator and install these two items: yum install epel-release. Yum install pangox-compat. Check if the Cisco AnyConnect app is installed. Before installing the VPN client, you can check to see if the Cisco AnyConnect app is already installed on your computer. Open Spotlight Search by clicking on the magnifying glass at the top right of your desktop, or via the keyboard shortcut command-spacebar. Type to search for the Cisco. Zscaler app also add routes on the machine. It has its own virtual adapter Issue we have is with a specific route 100.64.0.0/16 which gets added by Zscaler app When we connect to Cisco AnyConnect, most of the times 100.64.0.0/16 route disappears causing Zscaler app services to fail. As soon as we disable Cisco AnyConnect, route comes back. Whether providing access to business email, a virtual desktop session, or most other Android applications, AnyConnect enables business-critical application connectivity. The Cisco Umbrella module. Jadyr Pavao and I have the same issue. Update: It looks like AnyConnect and the nacl-development-environment plugin may have a conflict. Following Pete's recommendation, I removed the nacl-development-environment plugin, removed and reinstalled AnyConnect, and vpn is working again.
0.1. Requirements for Sociology Users
The VPN is NOT required for ...
PCs using wired connections in the Sociology/Psychology Building, the Markets & Management Office and the Social Science Research Institute when mapping to network home directory space.
PCs using Dukeblue encrypted wireless anywhere on campus when mapping to network home directory space. [This is an obvious incentive to discontinue use of unencrypted campus wireless.]
- SSH connections to Sociology Linux compute servers.
- Remote desktop connections to dedicated Windows office desktops.
The VPN IS required for ...
Mapping your Sociology network home directory to any laptop or home desktop using an off campus connection.
- Accessing protected data network resources governed by restricted data use agreements.
0.2. Affect of VPN Client on Other Network Connections
- When the VPN is connected or disconnected your IP changes. This will affect existing TCP connections such as email and SSH.
If you have an email client open before connecting the VPN, that session will be interrupted [this includes WebMail].
- If you have an active SSH session into a Sociology compute server, that session will be disconnected.
- VPN use and network drive mappings should be bracketed around other network activity to avoid broken connections.
- The sequence becomes:
- connect VPN
- map network drive
- load other network applications
- complete your work
- close out network applications
- disconnect VPN [this will also disconnect the network drive mapping]
0.3. Multi-Factor Authentication with the Duke VPN
As of February 6, 2018 Duke instituted multi-factor authentication as a requirement for use of the VPN. Details of MFA access are described in this OIT Knowledgebase article.
0.4. Installing the VPN
It is possible to perform a Java-based installation of the VPN by visiting http://portal.duke.edu. However, this method is notoriously unreliable because of frequent issues with Java.
