This is an example of how to connect to a Cisco VPN using netctl on Arch Linux.
First, install vpnc from Pacman. You’ll also need the netctl-vpc package from AUR (I use yaourt for this)
sudo pacman -S vpnc
yaourt -S netctl-vpnc
Next, create /etc/vpnc/vpn-<yourname>.conf with the following content:
Interface name tun<yourname>0
IPSec gateway <gateway>
IPSec ID <group name>
IPSec secret <group secret>
Xauth username <username>
Xauth password <password>
Pidfile /var/run/vpnc/vpn-<yourname>.pid
Create /etc/netctl/vpn-<yourname>.conf with the following content:
Description='Acme Corp VPN'
Interface=vpnc
Connection=vpnc
VpncConfig="/etc/vpnc/vpn-<yourname>.conf"
Then run it:
sudo netctl start vpn-<yourname>
ps aux | grep vpnc
To stop the VPN, run
sudo netctl stop vpn-<yourname>
