Connectivity
Wireless network connectivity is available during the workshop. The access to the Wi-Fi network is based on eduroam authentication (see more at www.eduroam.org) or on local authentication system..
Authentication
It is necessary to have valid credentials to connect to the eduroam wireless network. We believe that majority of you can get an eduroam account from your 'home' institution (or your domestic NREN). List of countries connected to the eduroam system and links to national information pages are presented at www.eduroam.org.
We provide temporary accounts for the rest of you who do not have the possibility of getting a regular account from your home organisation. These accounts are valid only during the workshop. The user names and passwords are available at the registration desk.
Available networks
There are two virtual wireless networks available at the workshop venue – eduroam and eduroam-simple.
eduroam
The eduroam network (SSID in fact) is the preferred and the most secure one. It requires authentication via the 802.1X protocol. So you have to run a special piece of software called supplicant (it is a built-in part of Windows XP/Vista) which will authenticate you to the network. Data communication is encrypted when using the eduroam network.
uk-simple
The second possibility is the uk-simple network, which implements authentication via a Web page. This solution is quite simple (you do not need any special software) but less secure – the data stream is not encrypted. You have to start a web browser after connecting to the uk-simple SSID and open any web page. You will be automatically redirected to the login page which asks for your user name and password. In case of successful authentication you will be granted network access.
Wired connectivity
There are also Fast Ethernet sockets available at the desks, but only every fourth of them is active (M004, M008, etc.). The behaviour of Ethernet network resembles the Wi-Fi: 802.1X authentication is supported. If you authenticate successfully, the network behaves like eduroam. If the authentication fails or if there is no 802.1X supplicant running on your computer, the network behaves like uk-simple with web-based authentication – you have to open an arbitrary web page to be redirected automatically to the login page.
Sending mail
We recommend you to use secured SMTP (port 465) to connect to your domestic SMTP server to send your mails. Plain SMTP connectivity (port 25) from the workshop networks is blocked. If you cannot use the secured SMTP, please modify the configuration of your mail program to use the local SMTP server smtp.eduroam.cuni.cz. This is the only plain SMTP server reachable from the workshop networks.
Assistance
We are ready to assist you if some problems arise – write mail to eduroam-support@cesnet.cz or ask at the registration desk.
