Cisco-osx-error-51-vpn-subsystem This is a nice little frustrating error message that displays on launch of the Cisco VPN client application for OS X in either 10.7 or 10.6. There are a couple of solutions to be found online, the first one is restart the VPN service via the command line. So in the Terminal run the following command: sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart This has fixed the issue for some users but not everyone, some users actually don’t have the file in their Start Up items and the problem was that the system extension for the VPN service wasn’t actually loaded in the first place so it couldn’t be restarted.
If this is the case load the extension with the following command and then all should work fine: sudo kextload /System/Library/Extensions/CiscoVPN.kext I have tested in 10.6.2 and works fine. As good practice make sure you have the latest version which is build 4.9.01, you can But Cisco have made it very difficult to just download their software, you need to create a login id and also get a service contract and then link that service to the login id – if you have these things you’ll be good to go, otherwise a royal pain. Take the easy route. Connect via OS X Network Interface But there is a much better way, if you have Snow Leopard 10.6 or Lion 10.7 you don’t need to use the Cisco client, OS X provides a Cisco VPN client built into the operating system.
Configure the client by going to the System Preferences Network Click on the “+” sign below the list of interfaces, select VPN from the interface list and Cisco IPSec from the VPN type, click create and enter your settings and your good to go.
I need to help someone running Mac OS X (10.5.8) to create a VPN tunnel to my Cisco ASA5505 firewall in order to access some files that reside on my Windows network. In the past, I have only connected other Windows users using the Cisco VPN Client software. I did obtain the Mac version of the Cisco VPN software (Cisco AnyConnect, which uses SSL), but the user feels that it should not be necessary to install this software on her Mac in order to access the shared drive.
I require VPN connections rather than poking a hole in the firewall for VNC, etc. Before I tell this user that my Cisco AnyConnect software.must. be installed, I wanted to see if there are other options, since I know very little about Mac OS X. I contacted Cisco, and they confirmed that other client software besides their own Cisco software can create VPN tunnels on this device, since VPN is built on an open standard like IPSec and SSL. However, they will not provide further details about non-Cisco software. Does anyone know if Mac OS X comes with VPN tunneling software?
What other VPN client software might be recommended for connecting a Mac to a Cisco firewall? Finally, once the VPN tunnel is established, does anyone know the best way to use Mac OS X to map the drive? As for 'mapping the drive', Mac OS X really doesn't have a concept of drive mapping. It will produce a network icon for any Windows share or subfolder of a Windows share depending on how you map it though. To connect to a Windows share, you would click 'Go' from the Finder menu and then 'Connect to server.' To reach the dialogue box for the network client. From there, you can enter an SMB URL such as 'smb://servername/share/' to create a desktop icon for the share.
If you want to create a desktop icon for a subfolder of the share, just add that to the URL ('smb://servername/share/f older1/') when you connect. To clarify, the PKG files.do. contain the Macintosh clients, but they are not the sort of PKG files that are used by the Macintosh Installer and will produce an error should you simply download and double-click on them on a Macintosh. They are installed on the ASA 5505 using the 'svc image' command in webvpn configuration mode and are used by the ASA for automatic installation of the client via the VPN's web interface.
The Windows and Linux AnyConnect VPN clients are also delivered in PKG format for this purpose.
