VPN client won't install on Ubuntu 9.10

[jelvington]

I am trying to install the 4.8.02.0030 VPN client for Linux on Ubuntu 9.10. The following information applies:

uname -a

Linux dell-desktop 2.6.31-19-generic #56-Ubuntu SMP Thu Jan 28 01:26:53 UTC 2010 i686 GNU/Linux

Pertinent output from vpn_install:

* Binaries will be installed in "/usr/local/bin".
* Modules will be installed in "/lib/modules/2.6.31-19-generic/CiscoVPN".
* The VPN service will *NOT* be started automatically at boot time.
* Kernel source from "/lib/modules/2.6.31-19-generic/build" will be used to build the module.

Is the above correct [y]

Hi,

Use the native client that comes with Ubuntu. It's called vpnc. Your install is probably not working cause you need to patch your kernel.

Thanks

I have tried using vpnc before with the Cisco concentrator and didn't have much luck. I will try it again.

What kernel patch are you referring to?

[kontrabant]

I got it working with this patch on Ubuntu && FEDORA (with slight modification of sed command):

Untar vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz

# Download patch file for newer kernel (2.6.30+) and apply it:

    wget http://lamnk.com/download/vpnclient-linux-2.6.31-final.diff

    cd vpnclient  

    patch < ./vpnclient-linux-2.6.31-final.diff

# Next we must edit a kernel source file

    sudo sed -i 's/const\ struct\ net_device_ops\ \*netdev_ops;/struct\ net_device_ops\ \*netdev_ops;/' `find /usr/src -name netdevice.h`

Yes, it is a one liner, you should copy & paste that command instead of typing The command's translation into English: find the string const struct net_device_ops *netdev_ops; and change it to struct net_device_ops *netdev_ops; in the file locates at

    find /usr/src -name netdevice.h

# And finally, install Cisco VPN Client:

    sudo ./vpn_install
