VPNs

What is a VPN and why do I care?
VPN stands for Virtual Private Network and it is invaluable when you want to use UCLA licensed resources from off-campus machines. 
 Specifically, the UCLA Library and the California Digital Library have licensed many different bibliographic and research databases that are restricted to UCLA machines. 
 If you have cable modem or DSL from home the BruinOnline VPN enables you to login and access those databases as if you were in your office at UCLA . Note: UCLA MFA enabled users should consult Authenticating Using Multi-Factor Authentication on the Campus VPN .

What is the Cisco VPN Client error message "Required VPN subsystem not available"
When starting up the VPN client software, I get the following error message: “Required VPN subsystem not available”. Why? 
 There are several possible reasons why this happened; most likely tied to the Cisco VPN Service. A lot of times I’ve seen this happen because the VPN service starts up before any working networking connection has started. Try the following steps: 
 1. Restart the Service a) Make sure you have a working network connection. If you are using the wireless UCLAWLAN , see if you can reach any UCLA website like http://www.bol.ucla.edu . If you are using a wired connection, see if you can reach any website like http://www.google.com b) Restart the Cisco VPN Service. Click Start → Run… → type in “services.msc” → Right-Click on “Cisco Systems, Inc. VPN Service” → select “Restart” 
 2. Reboot the Machine 
 3. Un-install and re-install the VPN service
