Directory where binaries will be installed [/usr/local/bin]
Automatically start the VPN service at boot time [yes]
In order to build the VPN kernel module, you must have the
kernel headers for the version of the kernel you are running.
Directory containing linux kernel source code [/lib/modules/2.6.15-26-686/build]
* Binaries will be installed in "/usr/local/bin".
* Modules will be installed in "/lib/modules/2.6.15-26-686/CiscoVPN".
* The VPN service will be started AUTOMATICALLY at boot time.
* Kernel source from "/lib/modules/2.6.15-26-686/build" will be used to build the module.

Setting permissions.
/opt/cisco-vpnclient/bin/cvpnd (setuid root)
/opt/cisco-vpnclient (group bin readable)
/etc/opt/cisco-vpnclient (permissions not changed)
* You may wish to change these permissions to restrict access to root.
* You must run "/etc/init.d/vpnclient_init start" before using the client.
* This script will be run AUTOMATICALLY every time you reboot your computer.
5. Depends on Linux Distribution Check/create appropriate startup script links. This depends on Linux distribution. For Debian/Ubuntu:
host:# ls -s /etc/init.d/vpnclient_init /etc/rc2.d/S85vpnclient_init
if you get this error
ls: /etc/rc2.d/S85vpnclient_init: No such file or directory
4 /etc/init.d/vpnclient_init
This depends on Linux distribution. For Debian/Ubuntu:
host:# cp /etc/init.d/vpnclient_init /etc/rc2.d/S85vpnclient_init
*note: It is important to understand that running the vpnclient_init script does not create VPN yet. The script only checks whether the system is configured properly and loads the necessary kernel module.
6.Configuration
[code][b]host:# cd /etc/CiscoSystemsVPNClient/Profiles/
host: /etc/CiscoSystemsVPNClient/Profiles# 'wget' www.linuxsig.net/files/mmuvpn.pcf
7. First time connect,else jump to #8
host:# /etc/init.d/vpnclient_init start
8. Change the permission so that nornal user can connect
host:# chmod 4111 /opt/cisco-vpnclient/bin/cvpnd
9. Connect to MMU VPN (normal user will do)
host:$ vpnclient connect mmuvpn
