authentication can be completed. Here one can choose between <strong>using</strong> self-generated or purchased<br />

certificates.<br />

Self-generated certificates is the most secure option, but entail significant extra work, since it is<br />

necessary <strong>to</strong> perform a separate certificate installation in every single client which is <strong>to</strong> be granted<br />

access <strong>to</strong> the <strong>wireless</strong> network. The way in which you save your own root certificate and your own<br />

certificate hierarchy is described in Chapter 4 of UFS112 [1].<br />

A simpler and “secure enough” way <strong>to</strong> achieve this is <strong>to</strong> make use of UNINETT’s server certificate<br />

service, SCS (http://www.uninett.no/scs). UNINETT is actually a member of TERENA’s TCS (TERENA<br />

Certificate Service) project and can supply user certificates <strong>to</strong> our members who belong <strong>to</strong> Comodo<br />

UserTrust. Most operating systems are accompanied by a client certificate with a public key from<br />

Comodo UserTrust. A detailed “cookbook” for ordering a UNINETT SCS certificate is available at<br />

http://forskningsnett.uninett.no/scs/hvordan.html. When you have received a certificate it must be<br />

installed in your RADIUS server. See Attachment C for installation of a certificate for FreeRADIUS 2.x.<br />

Once IEEE 802.1X is functioning internally, the national connection <strong>to</strong> <strong>eduroam</strong> can be configured. In<br />

general terms this involves rerouting the requests from users with unrecognised realms and accepting<br />

requests from one’s own users who are visiting other institutions. For more information about <strong>eduroam</strong>,<br />

see Chapter 10 of UFS112 [1] and the “<strong>eduroam</strong> cookbook” [2].<br />

- Obtain server certificate for RADIUS<br />

- Configure RADIUS server for the user database<br />

- Connect RADIUS server <strong>to</strong> <strong>eduroam</strong> (<strong>to</strong>p level in Norway is handled by<br />

hegre.uninett.no and trane.uninett.no)<br />

- Filter:<br />

o RADIUS Authentication UDP 1812 <strong>to</strong>/from hegre.uninett.no and<br />

trane.uninett.no<br />

o RADIUS Accounting UDP 1813 <strong>to</strong>/from hegre.uninett.no and<br />

trane.uninett.no<br />

o RADIUS Proxy UDP 1814 <strong>to</strong>/from hegre.uninett.no and<br />

trane.uninett.no<br />
