Using NetExtender
Step 6 Launch the NetExtender.tgz file and follow the instructions in the NetExtender installer. The new netExtender directory contains a NetExtender shortcut that can be dragged to your desktop or toolbar.
Step 7 The first time you connect, you must enter the SonicWALL SSL VPN server name in the SSL VPN Server field. NetExtender will remember the server name in the future.
Step 8 Enter your username and password.
Step 9 The first time you connect, you must enter the domain name. The domain name is case- sensitive. NetExtender will remember the domain name in the future.
Note You must be logged in as root to install NetExtender, although many Linux systems will allow the sudo ./install command to be used if you are not logged in as root.
