I am trying to setup Appgate Ip tunneling driver on my ubuntu 12.04 by following appgate instructions listed below:

Installation, Linux

Make sure the kernel has support for the Universal TUN/TAP device driver, and then log in as root and create a new directory somewhere, and copy the files

 ag_iptd
 add_route
 add_gw_route
 add_hosts_entry
 ag_iptd
 clean_hosts_file
 del_route
 del_gw_route
 del_hosts_entry
 interface_down
 interface_up
 remove_dns_server
 set_dns_server
 fix_localhost

into that directory. Then start the IPTD daemon by doing

 modprobe tun
 <directory-somewhere>/ag_iptd

There is also an init script 'ag_iptd.init' that can be installed to automatically start the IPTD daemon every time the OS is loaded.Please check the documentation of your Linux distribution on howto do this.

so is there any way to checkif my ubuntu 12.04 kernel has support for the Universal TUN/TAP device driver? and how to do so? Thanks,
