Fix Cisco VPN driver problems Apps
It seems that if you upgrade the Cisco VPN client from an older client, or even from the same version, something gets corrupted with the kernel extension. This fix has worked for me:
  1. Run /usr/local/bin/vpn_uninstall as root. Say Yes to all questions.
  2. Delete the vpn* packages from your /Library/Receipts folder.
  3. Install a fresh copy of Cisco VPN 4.6.03.0160
Note: Please be aware that Cisco themselves have said that this still does not work on dual-processor machines.

Fix Cisco VPN driver problems

This trick partially worked for me (and many other people) only after the network admin set the default user domain on the Cisco VPN server. I can connect. I can use SMB, LDAP, IMAP and everything else I try except the thing I really need it for, AFP access.

If I try to access an AFP share I get a kernel panic. I haven't seen any reports of working AFP shares using this VPN client.

Good job, Cisco. It's been years since we've seen something so important to the Mac community screwed up so badly. Get on the ball and make it work.

In the meantime, does anyone have a solution for the AFP problem. It's the only thing keeping many of us from using 10.4.

I haven't tried this personally, but you might try tunneling the AFP traffic through an SSH tunnel within the VPN tunnel. That would be a dirty, disgusting way of doing it though, not to mention pretty inflexible.

Tunneling AFP over SSH works with and without the Cisco VPNClient on 10.4.

Setting up on the client isn't too hard if you use SSH Tunnel Manager (http://projects.tynsoe.org/en/stm/).

NOTE: Don't turn SSH on your AFP server without securing it to a decent level (level 2 only, no root access, good passwords).

Nothing works for me. I have tried this on my own back when the new dmg was posted on Cisco's site and thought that maybe I missed a step. I did not. I get something that I have not seen posted elsewhere yet: It says that I am connected but no packets go through and I cannot disconnect the session either. I must force quit just to move on.

This is a brand new 1.67 GHz Powerbook G4 with 1 GB of RAM.

This stinks! I hope someone fixes it soon!

I have exactly the same situation on my PowerBook 12" 1.33. Everything seems to work fine (the client says that I'm connected) and that's it, the connection isn't working and it is impossible to disconnect or to quit the program. I gave up and decided to wait for the next version. Thanks, Cisco! :-(

Tris.

this tip worked like a champ. thanks...

remember to sudo rm the /Library/Recepts/vpn* files and dirs since they're owned by root.

also, i am not sure if this made a difference but after i did the clean install, i followed another tip regarding unloading and loading the kext especially when switching locations:

> sudo kextunload /System/Library/Extensions/CiscoVPN.kext
> sudo kextload /System/Library/Extensions/CiscoVPN.kext

(where > is the prompt of course)

i forgot to mention that i clearly was having problems with the vpn client prior to this tip; the client would launch, but never complete the connection.

The kext unload/load seemed to be the trick for me. Thanks

Fix Cisco VPN client
Authored by: gsgm on Jun 03, '05 11:29:20AM

We should probably suggest that users back up thier connection profiles before running the uninstall program.

At my company, the pre-share key is not available to eveyone, so that users cannot build thier own tunnels.

I don't have the exact path in front of me, but I believe the profiles are in /opt/Cisco_VPN/Profiles or /etc/opt/cisco_vpn/profiles.

Can anyone correct me on the path?

Will this fix all the freakin kernel panics and system hangs I've been getting?

Probably not if it is happening shortly after using afp.

The only kernel panics i have received using it are due to trying to use afp.

Shortly before my kernel panic I am connecting to another computer by entering in the connect to server dialog box only the computer name only, afp://machine_name.domain.xxx, using the browse method or any other way of connecting using apple file share protocol i received a kernel panic.

The only workaround for my kernel panics that I found was to use smb:// in the connect to dialog box. however the computer you are connecting to may not support it.

Instead of using 2 lines to unload and load the kext (to resolve the issue when changing networks/locations), try the following line in the shell instead:


sudo SystemStarter restart CiscoVPN
