I tend to prefer to use Juniper VPNs on Virtual Machines since it tends to take over the machine it's being run on. Sometimes at work we come across a customer site that requires the Juniper VPN client to be connected. Usually I use a WinXP VM that I've had for years but the last client had some requirements that couldn't be met that way. Linux Mint VM to the rescue, except out of the box it won't connect. These links helped me get the connection up and running (the big trick was replacing Java. The second big trick was kicking this off as root in the terminal so you get the prompts that you need to get)...
