[c-nsp] Cisco VPN Client Causes Mac OS X Crash

My laptop never freezes and I'll be connected with the VPN client the entire day sometimes. I'm running 4.9.01(0100) with OS X 10.5.5. I've used previous versions with OS X 10.4.10 and 10.4.11 along with 10.5 through 10.5.5 and never experienced any lockups with the Cisco VPN client. Do you have any other type of software like Parallels or VMWare Fusion installed? I think I've heard of some odd conflicts with similar programs. I've tried the trials and never saw anything, but don't have them installed on my MBP currently. Maybe it's a combination of network driver in OS X and the Cisco VPN client. I'm always using the Airport Extreme (en1 in my system). I also run IPv6, but I doubt that has any bearing on it.

Regarding the domain search list, I think I overlooked something very simple. It does indeed add it to my domain and search list in /etc/resolv.conf... what I was overlooking is I usually connect to FreeBSD machines that don't exist in the same search suffix where I modified my workstation to include this suffix. Nevermind on that. I'll have to add another domain if I can. It's on an old VPN 3002 concentrator.

Each time my laptop freezes up (and needs a hard reset), the
bug report indicates Cisco VPN Client had something to do
with it.

It only seems to happen when the client is connected to the
VPN server, but not, necessarily, when it's merely open and

There have been a number of reports on this issue (albeit in
slightly earlier versions of OS X):


I'm just not sure if these issues have propagated to 10.5.5.

It would be nice if Cisco released newer versions of this
code as often as they did for other OS's.

Works fine for me - we use EasyVPN:

conf t
 crypto isakmp client configuration group foo
  domain bar.com

It automatically gets added to my search list and system
domain name each time I connect (and removed when I
