eduroam: Internet access for roaming users

About eduroam

eduroam allows users visiting another institution connected to eduroam to log on to the WLAN using the same credentials (username and password) the user would use if he were at his home institution. Depending on local policies at the visited institutions, eduroam participants may also have additional resources at their disposal. All this with a minimum administrative overhead.

Participating institutions are located mostly in European countries, Asia-pacific region and Canada. There is more than 50 participating institutions of the eduroam project in the Czech Republic. The eduroam service is regulated by the Roaming policy.

Visiting users

If you have an eduroam account in your home institution, you can join the wireless network in the Center for theoretical study using any wireless equipped device (802.11b (WiFi) or 802.11g standard). There should be no re-configuration necessary in order to join our network. Basic parameters of the wireless access are:

• Wireless standard: 802.11b/g

• Outgoing port filtering: none, port 25 (tcp) is redirected to local mail server (147.231.54.40)

The whole area of the Center for Theoretical Study is covered by the WiFi signal.

CTS Accounts

Staff of the Center for theoretical study can apply for an eduroam (or local-only) account for the wireless network. Unique eduroam login/password will be provided upon request.

You can find a configuration guide for various operating systems (Windows (XP, Vista, 7), Linux, MacOS X) at eduroam.cz with the following changes:

Use these values at the EAP protocol properties window in MS Windows 7/8/10.
