Chapter 1      Configuring Clientless SSL VPN
  Configuring Browser Access to Plug-ins
* Consult the plug-in documentation for information on deployment configuration and 
restrictions.
These plug-ins are available on the Cisco Adaptive Security Appliance Software Download site. 
Detailed Steps
Follow these steps to provide clientless SSL VPN browser access to a plug-in redistributed by Cisco.
Step 1 .
Note The ASA does not retain the import webvpn plug-in protocol command in the configuration. Instead, 
it loads the contents of the 
csco-config/97/plugin directory automatically. A secondary ASA obtains 
the plug-ins from the primary ASA.
SSH The Secure Shell-Telnet plug-in lets the remote user establish a 
Secure Shell (v1 or v2) or Telnet connection to a remote computer.
Note Because keyboard-interactive authentication is not 
supported by JavaSSH, it cannot be supported with SSH 
plugin. (Keyboard interactive is a generic authentication 
method used to implement different authentication 
mechanisms.)

VNC The Virtual Network Computing plug-in lets the remote user use a 
monitor, keyboard, and mouse to view and control a computer with 
remote desktop sharing (also known as VNC server or service) 
turned on. This version changes the default color of the text and 
contains updated French and Japanese help files.
