Once Again! Cisco Vpn client Ubuntu (kernel: 2.6.27-9-generic) gives the same error!
 

Hi All:

I am trying to install cisco-vpn client in my Lenovo Y500 laptop running ubuntu. This is just not working. The very same famous "Failed to make module "cisco_ipsec.ko" error is propping. Tried out the various patches and solutions available on the internet. I have been stuck with this for nearly a month now. I would be grateful if you could help.

I am getting the following error:

By installing this product you agree that you have read the
license.txt file (The VPN Client license) and will comply with
its terms.


Directory where binaries will be installed [/usr/local/bin]

Automatically start the VPN service at boot time [yes]

In order to build the VPN kernel module, you must have the
kernel headers for the version of the kernel you are running.


Directory containing linux kernel source code [/lib/modules/2.6.27-9-generic/build]

* Binaries will be installed in "/usr/local/bin".
* Modules will be installed in "/lib/modules/2.6.27-9-generic/CiscoVPN".
* The VPN service will be started AUTOMATICALLY at boot time.
* Kernel source from "/lib/modules/2.6.27-9-generic/build" will be used to build the module.

Is the above correct [y]y

I would be more than pleased if you could help!

It asks if you have the kernel source for the kernel that's currently running....do you? Type in "uname -a" at a prompt...if it shows something other than the 2.6.27-9-generic you mentioned, that's your problem. Install the correct source, or upgrade your running kernel to match.

And have you contacted Cisco, to see if they could help?

Thanks Tbone! Actually, yes! I have got the correct kernel. I haven't contacted CISCO yet. I will do that now and will get back to this thread again. :)

Thanks, once again. Hopefully, the problem is solved.

The CISCO forums suck! I wasn't able to figure out how exactly should I post my question. It goes to askExpert and there is no immediate dialogue where I could write and post.

Wow..! Got it finally. I shouldn't have gone to the CISCO website. It only took my time. :(

Anyway, this tuxx guy has got a lot for us. Here is what I followed to get the cisco vpn work in Ubuntu Intrepid running 2.6.27 (note that the following patch is valid for 2.6.24+).

(go down to see : Patch to compile 4.8.01.0640 on Linux kernel 2.6.24+ and follow the instructions.)

Whoever this tuxx guy is, he is awesome! :) Whoever administers the CISCO forums, he should probably consider quitting the job. :P

Yeah, but alot of times, Cisco has the only answers...their forums do stink, but occasionally you can get lucky. Thanks for posting the answer, so others here can benefit from it too.
