## How I create an connection

### Cisco Concentrator

A connection to a cisco concentrator will be often found at universities. The students can fetch the cisco client for use with it. Normally the administrator provides a configuration file (*.pcf), which also can be included in the client.

The original cisco client has some problems:

- Needs a propriarity kernel module (can be build against own kernel)

- console only

You need: Username, password, VPN ID, IP address or hostname of the VPN gateway and preshared secret (PSK) if you dont have a cisco profile file (*.pcf).

To setup a connection to the Cisco concentrator you need to do the following steps:

1. Import the pcf file given from administrator (if available go to step 4)

2. Create a new profile with type cisco

3. Set gateway (hostname or IP address of the cisco concentrator) at general profile settings

4. Set at PSK profile settings (Pre shared key) the group password if you want to store it

5. Set at user settings the user name and password (if you want to store it)

### IPSec

...

### OpenVPN

...

### PPTP

PPTP is a old VPN protocol designed by Microsoft. Today its known to be insecure. Reasons are unencrypted control channel and design mistakes.

## Questions and Answers

What I have to do to get IPSec working?

Please install and configure FreeS/WAN (Linux 2.4.x)/ipsec-tools (Linux 2.6.x) first.

Then do the following steps:

1. Import certificate (if X.509 is needed and it is PKCS12 which is ended with .p12).

2. Setup a new connection (gateway, ...)

3. Setup authentication (username,password/certificate/pre shared key) of the newly created connection.

What I need for PPTP?

You need a kernel with MPPE support and the pptpclient.
