 +====== Cisco AnyConnect ======
 +
 +The AnyConnect [[http://de.wikipedia.org/wiki/Virtual_Private_Network|VPN]] client is a Java-based application, which establishes a SSL-encrypted tunnel to Cisco ASA 5500 gateways. With this tool communication over otherwise insecure networks like the unencrypted networks like GoeMobile can be secured.
 +
 +Usage of Apple  [[http://www.apple.com/support/bonjour/|Bonjour]] for Windows may cause connection problems with the Cisco AnyConnect client ([[http://support.microsoft.com/kb/970313|KB970313]]).
 +
 +<WRAP center round important 100%>
 +Due to the current load in VPN, two more servers were set up in addition to vpn.gwdg.de: ** vpn-b.gwdg.de ** and ** vpn-c.gwdg.de **.  We recommend using one of them. The current load of the all VPN systems are displayed [[https://status.gwdg.de/vpn|here]]. You may download the AnyConnect client [[https://ftp.gwdg.de/anyconnect/|from our ftp server]] using the username 'vpn' and the password 'fernzugriff'

 +==== Supported Operating Systems====
 +
 +AnyConnect supports the following operating systems:
 +
 +| Windows:                       | Windows 7 - 10                         |
 +| Mac OS:                        | Mac OS X ab 10.10                      |
 +| Linux (officially supported):  | RHEL ab 7 Desktop und Ubuntu ab 14.04  |
 +
 +We strongly advise Linux users to use the [[Linux|built-in OpenConnect client together with NetworkManager]] and not AnyConnect. This also works for the alternative servers b and c.
 +
 +
 +==== Installation Guide ====
 +1. Follow the link [[https://vpn.gwdg.de |VPN-GWDG]] and log in with your username and password as described below.

 +Now klick on the installation link to start the setup.
 +{{ :de:services:network_services:vpn:ac2.png?500 |}}
 +
 +Now the auto detection process will start. The following three bullet points will describe the different outcomes of this process.

 + 3. If the process detects a Java runtime environment capable of Java Web Start the browser will display one or two security requests.
 +After these security requests are granted, the installation process will commence.
 +
 +<WRAP center round tip 60%>
 +Java is not needed for running the application, only for installing it!
 +</WRAP>
 +
 +If the current user of the system does not have administrator privileges the administrator privileges will be requested or on Linux systems a
 +terminal with a prompt for the sudo password will be opened.
 +On Linux this will fail when //xterm// is not installed.
 +
 +After the installation the client will start and establish a connection.
 +{{ :en:services:network_services:vpn:cisco_anyconnect2.png |Connection Established}}
 +
 + 4. In modern browsers where Java is deactivated, the installation process will stop and an installation file is offered for download.
 +{{ :en:services:network_services:vpn:cisco_anyconnect3.png | Manual Installation}}
 +Download the installation file by clicking on the offered link and run the installation manually.
 +After the installation is complete the client will be launched. Enter //**vpn.gwdg.de**// as address for the connection, then click on connect to start the login.
 +
 +<WRAP center round important 60%>
 +Due to the current load in VPN, two more servers were set up in addition to vpn.gwdg.de: ** vpn-b.gwdg.de ** and ** vpn-c.gwdg.de **. We recommend using one of them.

 +Enter the same username and password as in step 1 and click on //ok// to complete the login.
 +After the login a connection will be established.

 +{{ :en:services:network_services:vpn:cisco_anyconnect5.png | login }}
 +
 +5. If a installation via Active X is possible and allowed by the user the installation will proceed automatically and a connection will be established.
 +
 +6. After a successful  installation the AnyConnect-Client will be shown in the system tray. By right clicking or double clicking the symbol in the tray the VPN can be disconnected.
 +{{ :en:services:network_services:vpn:cisco_anyconnect5.png | }}
 +After the first installation the AnyConnect-Client can be launched like any installed application without visiting vpn.gwdg.de .
