The Simple WLAN: ESSID wu
The easiest way to get online is to use the ESSID wu
After connecting, you'll be redirected to a login page, where you will have to provide your username and password. After some time you might need to authentificate again.
SSH etc will work.
Note: We've been informed that this WLAN is due to be turned off. But we don't know when. So it might be a good idea to prepare your laptop for the other WLAN (see below)
The Complex (but more secure) WLAN: ESSID wu-dot1x
This WLAN uses the ESSID wu-dot1x.
There are detailed (but german) instructions available here: http://www.wu-wien.ac.at/zid/anleitungen/wlan
There you can find instructions for various operating systems (if you don't speak german, ask some of the orgas for help, or try to navigate the windows by guessing :-)
Here's a translation of the Linux instructions (centered on Debian/Ubuntu):
We are all using Kernels $> 2.6.18$, so all further descriptions are based on those. Of course, you need the module that supports your WLAN-Card. You will also need these modules:
You can probably check if your WLAN Interface ist working, by typing this as
% iwlist scan 2>&1>/dev/null & sleep 5 ; iwlist scan | grep 'wu-dot1x'
You will also need the following packages installed:
% sudo apt-get install wpasupplicant wireless-tools ca-certificates
Configuration of WPA-Supplicant
If you are using a recent Ubuntu and your laptop is well configured, just tell the Network Manager that you want to use WPA2 and your username is <username> and your password is <password>.
Else, using Debian or some other linux, edit the file: /etc/wpa_supplicant.conf
If you need to download the root certificate, do this:
% wget -O GTE_CyberTrust_Global_Root.crt \
This should suffice. Start your connection with the following command:
% sudo wpa_supplicant -w -c /etc/wpa_supplicant.conf -i eth1 -D wext -d
wpa_cli should give you something like this if you were successful:
% /sbin/wpa_cli status
You should now be able to use the WLAN.
