Cisco module again doesn’t let us compile against the new kernel in Ubuntu 9.04 and 9.10 beta:
/home/lamnk/vpnclient/interceptor.c: In function ‘interceptor_init’:
/home/lamnk/vpnclient/interceptor.c:132: error: ‘struct net_device’ has no member named ‘hard_start_xmit’
/home/lamnk/vpnclient/interceptor.c:133: error: ‘struct net_device’ has no member named ‘get_stats’
/home/lamnk/vpnclient/interceptor.c:134: error: ‘struct net_device’ has no member named ‘do_ioctl’

Sometimes (even with new machines) there are problems at the client’s installation, for example:
Error 27848: Deterministic Network Enhancer installation requires a reboot first, to free locked resources.
After that the installation process is rewinded back and canceled. To fix it, open the command prompt as administrator (Right click on cmd then choose Run as Administrator). Type [...]
UPDATE: A new client for linux (4.8.02.0030) is out. You no longer need the patch for 2.6.24+ kernel (vpnclient-linux-2.6.24-final.diff). However the patch for 64 bit systems is still required and the CFLAGS variable in Makefile still need to be changed to EXTRA_CFLAGS.
June 26 2009: This post also applies to Ubuntu Jaunty Jackalope 9.04 (more than [...]
On some systems there is this problem with Cisco VPN service: cvpnd.exe must be excuted before you run the ipsecdialer.exe ( the GUI for the client ). But even if you start the service per hand in services.msc, it got killed in a few seconds after thus you can not run the client.
Update: thanks to [...]

UPDATE: A new client for linux (4.8.02.0030) is out. You no longer need the patch for 2.6.24+ kernel on 32 bit systems. However a patch for 64 bit systems is still required. Please click on the link right below to see the howto for 64bit.
UPDATE: 64 bit systems are a bit more complicated, please see [...]
I was playing around with Arch linux recently. It’s a minimalistic distro which lets you configure your system the way you want. Advatanges are booting time ( man it’s fast ), rolling release system so it doesn’t require you to install new release every 6 months like other distros, good package management tool alongside with [...]
The VPN connection on Vista drops after every 5-10 minutes idle times ( means no surfing or other net related activities ). Why ? Fuck me if i know. It doesn’t matter over wireless or LAN, wired connection breaks all the time too.
And the employees in uni are reporting disconnecting problem on XP with their [...]

Errm … with a patch. Cisco hasn’t released a new version for Linux yet.
Quick guide: ( I assume you knew all the requirements to install the Cisco client )
Go to the extracted vpn directory
wget http://tuxx-home.at/projects/cisco-vpnclient/cisco_skbuff_offset.patch
patch < cisco_skbuff_offset.patch
sudo ./vpn_install
That’s it.
The error: “Secure VPN connection terminated locally by the Client. Reason 412: The remote peer is no longer responding” means the software VPN Client detected that the VPN server is not responding anymore and deleted the connection. This is caused by several different reasons, for example:
The user is behind a firewall that is blocking ports [...]

Everyone has dealed with Cisco VPN Client on Vista probably knows the notorious Error 442 – Failed to enable virtual adapter. AFAIK this is a bug from Cisco that stays unfixed for at least 5 months (from the version 5.0.00.0340 released on May 2007 until now). Whether it is Cisco or Microsoft to point the [...]
