Instructions for Linux
1. Download and install the kernel headers corresponding to the kernel in use. Some distributions name this package kernel-headers, others name it linux-headers:
# sudo apt-get install kernel-headers-X.X.XX-X-XXX
or
# sudo apt-get install linux-headers-X.X.XX-XXX
Substitute the notation X.X.XX with the actual version of your kernel. You can get the version of your kernel by issuing the following command:
# uname -a
A valid version number could be, for example, 2.6.12-9-386.
2. Download and install the vpnclient:
Substitute the notation X Z with your university network's username and password:
wget –no-check-certificate –http-user=X –http-password=Z https://pro.unibz.it/vpn/Linux/vpnclient-linux-x86_64-4.8.00.0490-k9.tar.gz
3. Untar the source of vpnclient and install it.
Depending on the Linux Distribution you might need to install ''make'' and ''gcc-3.4'' apt-get install make gcc-3.4
# tar xfz vpnclient-linux-4.7.00.0640-k9.tar.gz # cd vpnclient # ./vpn_install
You will get some messages and you will be requested to answer to some questions:
Directory where binaries will be installed [/usr/local/bin] Automatically start the VPN service at boot time [yes] Directory containing linux kernel source code [/lib/modules/X.X.XX-X-XXX/build]
You only have to modify the predefined answers if they do not correspond to your actual situation. If everything works, you will see some compilation messages and then the installation program will stop.
4. Download the unibz.pcf configuration file from the site of the university. Substitute the notation XXX ZZZ with your university network's username and password:
# wget --no-check-certificate --http-user=XXX --http-password=ZZZ https://pro.unibz.it/vpn/Configuration/unibz.zip
5. Unzip the configuration file and copy it to the correct location:
# unzip unibz.zip # cp unibz.pcf /etc/opt/cisco-vpnclient/Profiles/.
6. Initialize the vpnclient:
# sudo /etc/init.d/vpnclient_init start
7. You can now start the vpnclient using sudo:
$ sudo vpnclient connect unibz
You will see some messages and then you will be requested to insert your username and password:
