Therefore, no fixes will be put in for this client.General QuestionsQ.

with the Cisco VPN Client Comments By Rob Griffiths, Macworld Oct 17, 2008 12:57 PM One of the most-used programs on my Mac is cisco vpn macbook the Cisco VPN Client, which is what I use to connect to Macworld’s VPN when posting articles such as this one. (OS X’s built-in VPN client also works, but it also logs me out of and then back into http://www.cisco.com/c/en/us/support/docs/security/anyconnect-secure-mobility-client/116080-productqanda-vpnclients-00.html iChat every time I 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 http://www.macworld.com/article/1136208/ciscovpn.html currently active and has an IP address 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

(error cisco vpn mac when installing Cisco) Error 28000 (error when installing Cisco because there is still (a part of) an old installation present on the system) When installing Cisco, a 'DNE error' occurs and you are asked to restart Windows XP When starting the VPN connection, the computer shuts down (or generates a blue screen). Error 427: unknown error occurred at peer. Mac Error 51: Unable to communicate with the VPN subsystem Solution: If you are running Cisco's VPNClient on Mac OSX, you might be familiar with (or tormented by) "Error 51: Unable to communicate with the VPN subsystem". The simple fix is to quit VPNClient, open a Terminal window, (Applications -> Utilities -> Terminal) and type the following: sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart and give your password when asked to. 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 scenarios.

on Mac OS X Posted October 10th, 2008 by John Bickar in Mac OS X SIG Answer mac vpn When using the Cisco VPN Client from off-campus, sometimes it will throw an error on launch and prevent you from connecting to the VPN concentrator. (The specific error is "Error 51: Unable to communicate with the VPN subsystem.") Usually, you can fix this by opening up Terminal and entering the following command at the command prompt (followed by hitting "Enter"): sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart However, if you run into Error 51 on the first launch of VPNClient, you'll get the following error: sudo: /System/Library/StartupItems/CiscoVPN/CiscoVPN: command not found In this case, deleting VPNClient from /Applications and reinstalling the latest version should fix the problem. (A reboot also might do the trick.) Another error that you may encounter is "Error 5: No hostname exists for this connection entry. Unable to make VPN connection." In this case, right-click the Stanford_Public_VPN connection entry in the connection window and choose Modify from the contextual menu. In the host field, enter su-vpn.stanford.edu and click Save. (Uninstalling and reinstalling also should fix this problem.) Using OS X's built-in VPN vs. Cisco client Submitted on May 27th, 2011 by mallis The instructions for connecting via VPN suggest downloading the Cisco VPN client. If OSX is running in 64-bit mode (mine is) the Cisco client will not work at all. I followed the instructions here: http://anders.com/guides/native-cisco-vpn-on-mac-os-x to add a VPN connection using OS X's built-in Cisco VPN functions. It was easy, and better than adding another kernel extension to the mix, especially one originally designed to run under OS X 10.4/ The information gathered on the
