-Cisco Anyconnect VPN Client installs okay for 32 bit version on a 32 bit machine
+==== VPN Notes ====
-The 64 bit version does not work - connection gives error message.
+__Using CentOS VPNC, OpenVPN and Network Manager to get VPN services__
-To install the 32 bit on a 64 bit machine, you need to do the following:
-yum install libxml++.i686 atk.i686 gtk2.i686
-Then when starting the vpn /opt/cisco/vpn/bin/vpnui you will still get some error messages going by but it works.
-An alternative is to use OpenVPN.

-The older Cisco VPN client does not install.  It gives a failed to make module "cisco_ipsec.ko".
-**Instead, use CentOS VPNC, OpenVPN and Network Manager to get VPN services.**
 First enable EPEL repo using one of these links:

-Then yum install NetworkManager*.  This command should install *vpnc* and *openvpn* but double-check to be sure.
+Then:
+yum -y install NetworkManager*
+yum -y install *vpn*
+yum -y install openconnect*
 Then go to network manager or right-click the network icon in the task bar and add a new connection, VPN.
 Enter all the appropriate settings as given by work and then __reboot the machine__ otherwise your configuration will not save and you will get an error "no valid VPN secrets".

+To connect to a Cisco AnyConnect VPN server, use openconnect as listed above.  Reboot the computer after installing the VPN packages and set up the connection entering the IP address for the Gateway.

+The ntpd service may not be able to connect to time servers; remember to update /etc/ntp.conf and possible /etc/ntp/step-tickers with time sources that are reachable when the machine has the VPN connected.

+Notes from Scalio:
+  * Install the vpnc rpm and any dependencies, if not already installed.
+  * As root, use visudo to add the following entries to the sudoers file without the surrounding "<>":
+        <your user name>   ALL=(root) NOPASSWD: /usr/sbin/vpnc
+        <your user name>   ALL=(root) NOPASSWD: /usr/sbin/vpnc-disconnect
+  * As root, create a vpn configuration file (I called mine myvpn.conf) in /etc/vpnc containing the following:
+        IPSec gateway XXX.XXX.XXX.XXX
+        IPSec ID XXX
+        IPSec secret XXXXXXXXX
+        Xauth username <your user name>
+        Xauth password <your password>
+  * Change file permissions on your vpnc configuration file to 600.
+  * Copy the two attached files to some place in your path.  I put them in ~/bin.  Make sure you they both have execute permission.
+  * Use the scripts to start/stop VPN sessions.  I use this from inside a VirtualBox Linux guest.  Occasionally, your vpn sessions will terminate without any notification.  If you aren't getting a response from an established session, you can just do "start_vpnc" again and you shouldn't even get kicked out of any remote terminal sessions you have running.
+<code>
+#!/bin/bash
+# start_vpnc.bash
+sudo /usr/sbin/vpnc --natt-mode cisco-udp myvpn
+#!/bin/bash
+# stop_vpnc.bash
+sudo /usr/sbin/vpnc-disconnect
+</code>
