install cisco vpn client on ubuntu

Ubuntu ships by default with the plugin for the Point-to-Point Tunneling Protocol (PPTP), but we need the plugin for the Cisco Compatible VPN (vpnc), that provides easy access to Cisco Connector based VPNs. To install the vpnc plugin, open your terminal and run:

CopyOpen Ubuntu Software Center and install Openconnect
sudo apt-get install vpnc
sudo apt-get install network-manager-vpnc
