OU recently acquired matlab for all students and faculty. However, to use at one, one needs to setup vpn. The defacto cisco vpn provided on the OU website is really dated. It doesn’t work with ubuntu unless one does some patches. I gave up after a few tries but instead I found one post mentioned about vpnc. And it is really easy to setup.

After installing it from synaptic, run

sudo vpnc

then input the following info (ur <4×4> and <password> needed of course)

Enter IPSec gateway address: soonerconnect-cox.ou.edu
Enter IPSec ID for soonerconnect-cox.ou.edu: users
Enter IPSec secret for users@soonerconnect-cox.ou.edu: ou-vpn
Enter username for soonerconnect-cox.ou.edu: <4×4>
Enter password for chen6802@soonerconnect-cox.ou.edu:  <password>

One can setup even more conveniently as below if network-manager-vpnc is also installed. The version shown is Ubuntu 8.10.
