to the native OS X client. If you are running Cisco's mac cisco vpn error 51 snow leopard VPNClient on Mac OSX, you might be familiar with (or tormented by) "Error 51: Unable to communicate with cisco vpn error 51 mac lion the VPN subsystem". The simple fix is to quit VPNClient, open a Terminal window, (Applications -> Utilities -> Terminal) and type one of the following: (for older versions)

sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart (for newer versions) sudo kextload /System/Library/Extensions/CiscoVPN.kext and give your password when it asks. This will stop and start the "VPN Subsystem", or in other words restart the CiscoVPN.kext extension. Cisco seems to have problems when network adapters disappear and reappear, something that happens commonly in Wireless or Dial-up scenerios. Sometimes putting a system to sleep,

disconnecting an Ethernet cable or simply reconnecting your wireless will cause CiscoVPN to loose track of the network adapters on the system. Considering that CiscoVPN is typically used by telecommuters, this is an astonishing oversight on Cisco's part. The above hack should side-step all of these issues by causing the CiscoVPN to re-initialize. It makes one ask, why couldn't Cisco have just put the restart into their client? Or a better idea would be to not reinvent the wheel and use the existing IPSec VPN support in OSX! Am I missing something? EDIT: The MacWorld guys came up with a simpler way to do the same thing: sudo SystemStarter restart CiscoVPN Posted by Anders Brownworth Monday, November 13, 2006 7:25 PM Tweet Comments (269) Jeff from Chicago #1 | Friday, March 23, 2007 6:53 AM Thanks for the tip - this worked like a charm. todd from boston #2 | Thursday, March 29, 2007 10:29 AM you the man - thanks!

Someone suggested I hold down the 2 and 3 keys when I restart so that the system will revert back to 32 bit (whatever that means). It worked after I did that. I just need to remember to hold it down whenever I turn the computer on. Or else, I'll have to restart to access the VPN.I'm not sure what gets affected when you do this though. But, I seem to be able to carry on very well.

I ran into this issue while trying to get the Mac version of Cisco VPN Client to run on the only Mac user's system I support. After a little bit of searching I found out that the user's system is 64-bit and the Cisco VPN Client only comes in the 32-bit cisco vpn error flavor. The easiest way to get Mac OS X into 32-bit mode is to restart the computer and hold the 3 and 2 keys while it boots. Likewise, if your Mac normally boots in 32-bit mode you can hold down the 6 and 4 keys to get it to boot into 64-bit mode. You can check to see what architecture you are running by running this command in the terminal: [bash]systemsetup -getkernelbootarchitecturesetting[/bash] To set your machine to always boot into 32 bit mode enter this command and reboot: [bash]sudo systemsetup -setkernelbootarchitecture i386[/bash] To set your machine to always boot into 64 bit mode enter this command and reboot: [bash]sudo systemsetup -setkernelbootarchitecture x86_64[/bash] Cisco Cisco / OS X /
