Linux can be connected to a Cisco VPN with VPNC.

sudo apt-cache search VPNC

You can see that a number of related packages have been returned. One of the VPNC is what we need. So

sudo apt-get install VPNC

This is core, without GUI, input

sudo vpnc

Start, will guide you to enter your VPN parameters. The VPN parameters of the school I use are as follows
Ipsec:vpn-ct.shanghai.nyu.edu (any one of several addresses provided by NYU)
Ipsecid:nyu-vpn
IPSec secret:nyu-net
Usrname: (NYU net ID)
Password: (NET ID password)

You will then be prompted to connect successfully. Next time the connection, but also to enter again, very troublesome, how to do it. View man will tell you that there is a nobody profile default.conf can use, the location of this file in/ETC/VPNC

Edit this file and save it, next time Enter:

sudo vpnc
//or
sudo vpnc xxx.conf

You can connect to a VPN.

In addition, there is a GUI that is integrated into Ubuntu that can be used.

sudo apt-get install NETWORK-MANAGER-VPNC

Then, select the Network icon for the action bar, have a VPN connections option, select
Configure>>add>>cisco compatible VPN (VPNC)
Jumping out of the boot interface, we just installed the NETWORK-MANAGER-VPNC, parameter settings above terminal configuration.
