Want to know more about AnyConnect licensing? Here are some resources:

Step 1

Open a web browser and navigate to the Cisco Software Downloads webpage.

Step 2

In the search bar, start typing ‘Anyconnect’ and the options will appear. Select AnyConnect Secure Mobility Client v4.x.

Step 3

Download the Cisco AnyConnect VPN Client. Most users will select the AnyConnect Pre-Deployment Package (Linux 64-bit) option.

The images in this article are for AnyConnect v4.9.x, which was latest version at the time of writing this document.

If you purchased a license and you are unable to download AnyConnect, call +1 919-993-2724. Select option 2. You will need to know your Cisco ID (the one you use to log into Cisco.com) and the sales order number when you call. They will get that situation all straightened out.

Step 4

Open the Terminal by pressing Ctrl+Alt+T on your keyboard. To navigate to the folder where you have downloaded the AnyConnect Client Package, use the command, ‘cd directory name’. For more information on the ‘cd’ command, click here.

cd [Directory Name]

In this example, the file is placed on the Desktop.

The directory may be different based on the location of the AnyConnect file download. For long filenames or paths, start typing some characters and press the tab key on your keyboard. The filename will auto-populate. If it doesn’t even after you press tab twice, it indicates that you need to type more number of unique characters. Alternately, you can use the ‘ls’ command to list the files in your current directory.

Step 5

The initial download is a tarball archive (several files packed into one), which must be extracted. The command ‘tar xvf filename’ will extract the contents to the same directory in which the initial file is located.

tar xvf [Filename]

For more information on the ‘tar’ command, click here.

Step 6

Once the folder is extracted, use the ‘cd directory name’ command again to navigate into the folder.

cd [Directory Name]

Step 7

After navigating into the main folder, ‘cd’ into the vpn sub-folder.

Step 8

To run the AnyConnect install script, type ‘sudo ./vpn_install.sh’. This will begin the installation process using superuser permissions.

For more details on the ‘sudo’ command, click here.

Step 9

Accept the terms in the license agreement to complete the installation by typing ‘y’.

The AnyConnect installation should complete, and the Terminal window can be closed.

Using AnyConnect Secure Mobility Client v4.9.x

Step 1

To access the Anyconnect app, open the Terminal by pressing Ctrl+Alt+T on your keyboard. Use the command, ‘/opt/cisco/anyconnect/bin/vpnui’.

If you encounter any errors through the Terminal, you can access the app from the applications menu as shown below.

To access the applications menu using the User Interface (UI), click on the start icon (appears as nine dots on the lower left corner). Choose the Anyconnect app.

Alternatively, press Super+A (Super key is the windows icon key) on your keyboard to bring up the search bar. Start typing ‘Anyconnect’ and the app will appear.

Step 2

Click on the Anyconnect app.

Step 3

Enter the IP Address or Hostname of your desired server followed by the port number.

For RV340 family, the default port number is 8443.

Step 4

Some connections may not be secure using a trusted SSL certificate. By default, AnyConnect Client will block connection attempts to these servers.

Uncheck Block connections to untrusted servers to connect to these servers.

Uninstalling AnyConnect Secure Mobility Client v4.9.x

Step 1

Using Terminal, navigate to the folder that contains the uninstall shell script using the ‘cd’ command.

In a default installation, these files will be located in /opt/cisco/anyconnect/bin/.

Step 2

To run the Anyconnect uninstall script, enter ‘sudo ./vpn_uninstall.sh’

This will begin the uninstall process using superuser permissions. For more information on the ‘sudo’ command, click here.

Step 3

At the prompt, enter the sudo password and the client software will complete uninstallation.

HOWTO connect to a company’s VPN using the Cisco VPN client on linux

This HOWTO explains connecting to a VPN gateway over IPSec in «cert auth mode» utilizing the Cisco VPN client. The «cert auth mode» refers to the terms used in the vpnc man page, i.e. server + client certificates. The «cert auth mode» has not been implemented for vpnc, otherwise we would just use vpnc and avoid the headache that follows. openconnect is another alternative, but it does not support IPSec, only HTTPS/SSL. This HOWTO is written with the aim to provide a single document to describe all the steps required, instead of having to search many different things on the Internet.

This HOWTO was written from the perspective of an openSUSE 12.1 user, running a 3.1.10-1.9-desktop x86_64 kernel. The author does not claim to be an expert on any terms used, so if you find a mistake then please submit a patch.

Get the certificate provided by CompanyA

The company we are trying to connect to should provide us with some sort of a certificate, e.g. certificate.pfx. This type of certificate is a PKCS12 certificate which bundles the CA certificate for server authentication, the client/user certificate as well as the primary key. Save it somewhere on disk, e.g.:

Install and prepare kernel-source for our linux distro

In order to «compile» (Cisco calls it «install») the Cisco IPSec kernel module (see later section) we need the kernel sources for our distro. In openSUSE 12.1 do the following:

Make sure the version that will be installed is the same as the version we are currently running:

When the kernel-source has been installed, execute the following as root:

Download, patch and install Cisco VPN client

Now that the kernel-source has been installed we can download, patch and install the Cisco VPN client with the following steps (as root):

Remember to specify the kernel-source directory as /usr/src/linux- .

The module will be installed to /lib/modules/ /CiscoVPN/cisco_ipsec.ko.

Start the Cisco VPN daemon

The Cisco VPN client installation suggests starting the vpncclient_init service, so do it:

If we get errors such as:

then (1) we compiled/linked the module with the wrong kernel-source or (2) we forgot to symlink the Module.symvers file. We will have to repeat some of the steps above.

Import provided certificate for use with Cisco VPN client

The provided PKCS12 certificate should now be imported. The following commands can be used (as root):

Supply the certificate filename, e.g. /tmp/certificate.pfx as well as the password with which the certificate is locked/encrypted. Next, enter a password that we will easily remember.

View the imported certificate:

and provide the number of the corresponding certificate when asked. The certificate information will be displayed. Take note of the «Subject» and «Serial #» fields as they will be required in the next step.

Configure Cisco VPN client

Configure a profile for connecting to CompanyA. Let’s call the profile «CompanyA». As root:

and change the following properties as follows:

The moment of truth has arrived. To connect to the VPN of CompanyA, simply execute:

assuming /usr/local/bin is in our PATH.

When prompted, provide the certificate password we chose in a previous step as well as our unique username and password that should also have been provided by CompanyA. We should now be connected.
