Virtual Private Network (VPN) is a great option to access to your office resources from home in secure way and Cisco VPN is one of more efficient and robust type of VPN.
Cisco VPN configuration can be setup in 2 ways: using authentication data or PCF file.
In this article, we will describe how to setup Cisco VPN using PCF on an Ubuntu system.
First of all, we need vpnc client, so let’s open a terminal and digit:
$ sudo apt-get install vpnc
Now we will use a little tool to convert PCF file released by our VPN administrator into a configuration file:
$ pcf2vpnc ciscovpn.pcf ciscovpn.conf
This operation will produce a new file with content like this:
## generated by pcf2vpnc IPSec ID PIXEL IPSec secret [email protected]@vrrav22ve2 Xauth password Xauth username
in which we have to add our VPN username and password.
At this point, we can start VPN connection using the command:
$ sudo vpnc /path/to/ciscovpn.conf
And disconnect it using:
$ sudo vpnc-disconnect
