connect or disconnect from the VPN. The Cisco VPN Client doesn’t have this annoying problem, so I use it instead.) While the Cisco VPN Client works well most of the time, sometimes when I try to launch the application, I’m greeted with this error message in place of the usual connection dialog: Error 51: Unable to communicate with the VPN subsystem. Please make sure that you have at least one network interface that is currently active and has an IP address cisco vpn client mac osx and start this application again. The error is clearly incorrect, because my machine’s networking capabilities are otherwise fine—I can browse the net, send and receive e-mail, and connect to other machines in the house. I don’t get the error message all the time, and I don’t really know what causes it. It does seem to happen more often if I’ve slept and woke the machine, or moved it from one defined location to another, but even then, it’s not predictable. All I know for sure is that it’s annoying, because (until recently) the only fix I was aware of was to reboot the machine. One day, after probably the second or third time I’d restarted my machine, I decided there must be a better solution, so I went digging to see if anyone else had already found one—and they had. As detailed on the linked site, the solution is a relatively simple command that you execute in Terminal (found in Applications -> Utilities). After discussing the Terminal command with a friend, he came up with an even simpler version that works just as well: sudo SystemStarter restart CiscoVPN You’ll need to be an administrative user to run this command, and provide your admin password when asked. You won’t see any output from the command; the Terminal prompt will return when it’s done. After using the above command, the Cisco VPN Client should run without any problems—at least until the n

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 client 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 /

Mac OS 10.7/Lion runs the 64-bit kernel by default. Users will see the error "Error 51: Unable to communicate with the VPN subsystem" when starting the VPN. Until Cisco releases a compatible client, there are a few workarounds available: Set Mac OS X to boot using the 32-bit kernel according to the instructions in Apple's support article Configure the Mac OS X built-in VPN client to connect to the UCLA VPN using any one of the following protocols: PPTP Cisco IPSEC Please note that this issue is not specific to Mac OS 10.7/Lion. Apple has a list of Macs that use the 64-bit kernel by default as well as instructions to find out if you're using 64-bit mode.
