Cisco VPN Client on Ubuntu 8.04 64-bit

June 3, 2008 Posted by mitch | cisco, ubuntu | 0 Comments

Last night i decided that running the server kernel for the PAE mods isn't really a good fix on my new ThinkPad T61, so I installed the 64bit version of Ubuntu.

I had a few issues with getting the Cisco VPN client installed but found these instructions to help.

1. Untar the VPN Client
# tar xzf vpnclient-linux-4.8.01.0640-k9.tar.gz

2. Download the patch #1
# wget -q http://projects.tuxx-home.at/ciscovpn/patches/vpnclient-linux-2.6.24-final.diff

3. Download the patch #2
# wget -q http://projects.tuxx-home.at/ciscovpn/patches/cisco_skbuff_offset.patch

4. Change to the vpnclient diretory
# cd vpnclient

5. Apply the patch #1
# patch <../vpnclient-linux-2.6.24-final.diff
patching file GenDefs.h
patching file interceptor.c

6. Apply the patch #2
# patch <../cisco_skbuff_offset.patch
patching file frag.c
patching file interceptor.c
Hunk #1 succeeded at 646 (offset 16 lines).
Hunk #2 succeeded at 685 (offset 16 lines).
Hunk #3 succeeded at 807 (offset 16 lines).
patching file linuxcniapi.c
patching file linuxkernelapi.c

7. Open your "Makefile" and rename the CFLAGS line to EXTRA_CFLAGS

8. Now the patches have been applied and you can safely install the client
#./vpn_install
