Installing the VPN Client

In order to install the VPN Client, which requires registry changes to your Mac OS 10.1, you must be in root mode.

Follow these instructions in order to install the VPN Client:

1. Complete these steps in order to enable the root user and set up the password:

   1. Enable Root mode.

   2. Sign into your Mac as a regular user.

   3. Double click the Hard Drive icon.

   4. Choose Applications > Utilities > Netinfo Manager.

      

   5. From Netinfo Manager, choose Domain > Security > Authenticate.

      

      You are prompted for administrator password for the admin user. The admin user is the one who created the administrator account.

   6. From Netinfo Manager, choose Domain > Security > Enable Root User.

      

   7. After you enable the root user, log in as the root user.

2. Locate the the VPN Client TAR file as downloaded from Cisco web site, and double-click the TAR image in order to unpack it.

   The files will be placed into a folder called "vpnclient" on your desktop. The folder includes the necessary files to install and uninstall the VPN client.

3. From the terminal window, go to the vpnclient folder by changing the directory "/" folder, such as "cd \desktop/vpnclient," and pressing Enter. Then type ./vpn_install to install the VPN Client in the desired folder.

   

   

4. Choose Applications > Security > Netinfo Manager, and then choose Domain > Security > Disable Root User in order to disable the root user.

   

5. Choose Domain > Security > Deauthenticate in order to deauthenticate the root user.

   

6. Quit the Netinfo Manager.

7. Restart your Mac and log in as a normal user. This starts the VPN service that is installed with the VPN Client.
