I can't see anything in the Network list and Command-K doesn't work either ("Connection Failed"). http://forumyaren.com/vpn-client/vpn-client-error-435.php
Apparently a software update around March of 2007 broke the Cisco VPN software's ability to connect though it wouldn't show the "Error 51" that this page talks about. massmind.com Craig from Colorado Springs #20 | Sunday, October 14, 2007 11:10 AM Hmmm... Deise Tsukada from Sao Paulo, Brazil #171 | Wednesday, February 3, 2010 7:32 PM Thank you Tela, it worked to me! (Mac OS X 10.5.8 and Cisco VPN Client 4.9.01 (0100)) Running the suggested command: sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart Password: Stopping Cisco Systems VPN Driver kextunload: unload kext /System/Library/Extensions/CiscoVPN.kext failed Starting Cisco Systems VPN Driver extension /System/Library/Extensions/CiscoVPN.kext does not contain code for this

It is precisely the same. Disable all Parallels network adapters in the network preferences. You won’t see any output from the command; the Terminal prompt will return when it’s done. 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.
Anders from RTP #30 | Thursday, November 22, 2007 7:38 AM Are you using OS X 10.5 Leopard? Since it was working I compiled and installed quite a few unix packages. Tiger has no problem with the VPN Client plus Remote Desktop connection to the Windows server at work. Saves a lot of time and frustration.
Please try again later. it was working fine for a while, then error 51 started and I got around it by disabling airport, but just now it is coming up with error 51 everytime :( If you've seen this problem Another case of Leopard VPN malfunction within VM Monday, December 31, 2007 Bruce Johnson is another user having problem getting a virtual private network connection from As of May 2007, Apple has released an update that fixes this issue between Cisco VPN and OSX so now things work again as expected.
I've read tens or hundreds of threads in all kinds of likely forums, but there seems to be no solution.
swoodie from berkeley #83 | Friday, June 13, 2008 11:06 PM thank you! Somehow, sometime, something changed and it began working! (I'm currently running 10.5.2) It may have been a coincidence with the rebuilding of my hard drive. I've done everything conceivable, including reinstalling the client.
Previous reports were with Mac OS X 10.5.3, but Hawkins is using 10.5.6: I saw your post through searching Google for posts related to a problem that I have with OS click site The issue returned so I also turned off automatic updates for the OS and all applications. Apple.com doesn't need to go through the corporate network, for example. it saves me a lot of reboots now.
Personal vpn Yes, the fix worked Leave your comment Please be polite. My problem is while VPN works fine with my wired and wireless (802.11g) networks it won't connect when I use a dialup connection. Tela from Washington DC #43 | Saturday, December 22, 2007 5:00 PM The above solutions have not worked for me but I found another fix that does work. http://forumyaren.com/vpn-client/vpn-client-error-39.php I'm sure there is a good reason somewhere but there is probably a good compromise that could be worked out where this sort of thing won't be an issue.
I am a die-hard mac user but unfortunately am also a system administrator for a a Windows network and rely on Cisco VPN to connect from home. mpeg2tom from LA #57 | Saturday, February 23, 2008 2:50 PM Yep, it worked for Cisco 4.9.01 on OS X 10.5.2 MacBook Intel Michael from Horsham PA #58 | Tuesday, February This feature is not available right now.
I got everything working, I can connect no problem, but whenever I try to connect to something in Safari, it doesn't properly resolve the DNS.So, let's say we have our Intranet Chuck Burt from Boston Area, MA, USA #108 | Thursday, September 18, 2008 12:13 PM I just wanted to point out that I come back and refer to this article time You might have a newer version partially installed over an older one. Jack from Palo Alto, CA #48 | Saturday, January 26, 2008 1:53 PM Thanks for the tip!
Anders from Boston, MA #173 | Saturday, February 6, 2010 8:03 AM Rabbid: In my opinion, that's not a good rationale for writing bad software. Thanks! sateesh from RTP #238 | Wednesday, August 10, 2011 6:43 AM Worked liked charm. More about the author Why are only passwords hashed?
It should work. Bert Woudwijk from Rotterdam, The Netherlands #132 | Tuesday, January 6, 2009 9:57 PM I have error 51 with Windows XP. Awesome it worked! Another word for something which updates itself automatically How to defeat the elven insects using modern technology?
After the next restart the problem was away... The client starts fine and I can click connect but it thinks for a few seconds and then goes back to disconnected (I never get the password challenge popup) Does anyone Specifically, Oliver Block suggests a Cisco feature called Split-DNS: Perhaps the administrator of the VPN device disabled split-DNS. I'm using vpnclient-darwin-4.9.01.0100-universal-k9.
And I no longer use the Verizon-provided software. Here are my 2 cents on this: Initially i had Tiger OS and Cisco VPN installed. Ran Terminal command before first launch.
