VPN - Virtual Private Network connectivity


VPN Connectivity   
 

What is a VPN?
VPN [Virtual Private Network] is, as implemented at the UofC, a private encrypted network connection between your computer and the campus network.  When you initiate a VPN connection, all of the network traffic is encrypted and transmitted to a point on campus where it is decrypted. 
 

Why is this important?
The advantage of the VPN is that you get the benefit of being on campus when you are abroad.  Since certain services are restricted from off-campus connections, the VPN system can allow you to access these services from home or the road.

In regard to Particle Theory, there are several systems which require VPN connectivity to access from off campus.
bangcompute.uchicago.edu -  The computation node
fileserver.uchicago.edu - the mirror of your Macintosh home space
*I believe some of the Library resources require on campus connectivity.

How do I use the VPN?

NSIT has recently upgraded their VPN infrastructure.  The previous client software will continue to function but I recommend that you upgrade.  PSD Desktop Support will perform the upgrade for you, or you can follow these directions.

Uninstall:
instructions pending

Installation of latest client:
-  Navigate to http://cvpn.uchicago.edu
-  Log in with your CNET credentials (not your Theory account credentials)
-  The cvpn site will launch a JAVA installer for your platform and initiate a connection.

Upon completion of the web install, you will be able to connect through the VPN by running a local software package, in the "Cisco" application directory.  You can also navigate to http://cvpn.uchicago.edu to initiate your VPN connection.

** The Current CVPN Cisco client has been, on occasion, unstable under OS X 10.6.2 (and earlier).  I've noticed some issues, particularly when I connect, disconnect, connect repeatedly.   For optimum stability, disconnect manually when you're done with your session (icon availalbe on top menu bar) and reboot your machine occassionaly.
