There are several problem common problems with Juniper SSL VPN on support of Linux clients: 1.Most 64-bit platforms are not supported. 2.Junos Pulse SSL VPN does not support Linux at all. Best way to cover problem “1” is: http://ubuntuforums.org/showthread.php?p=11189826#post11189826 There is also well known mad-scientist way but its more complex. Problem “2” is a bit more involved. In my case when I login to Juniper SSL web interface it run host-checker and as Linux is not supported the web form does not have way to launch Junos Pulse SSL VPN client.
