vpnc is a VPN client compatible with cisco3000 VPN Concentrator (also known as Cisco's EasyVPN equipment). vpnc runs entirely in userspace and does not require kernel modules except for the tun driver to communicate with the network layer. It supports most of the features needed to establish connection to the VPN concentrator: MD5 and SHA1 hashes, 3DES and AES ciphers, PFS and various IKE DH group settings.

files often spread with proprietary (read Cisco) VPN-clients into
vpnc-configuration files, usually named *.conf.
If [vpnc file] is not specified, the result will be printed to STDOUT. If
specified, it will be written to that file. Please make sure that it has
appropriate permissions as it may contain sensitive data!
