Proxy access through WiFI

Print PDF

From 1800 hrs on Feb 11, 2014 CSC is changing the proxy authentication mechanism for internet access when connected through the WiFi network.

When connected through the WiFi SSIDs IITD_WIFI{1,2,3} and EDUROAM, users will automatically be logged on to their respective proxy servers. Users will still be required to specify the correct proxy server in their system or web browser. The proxy server can be specified either as an automatic proxy configuration URL (such as http://www.cc.iitd.ac.in/cgi-bin/proxy.category) or manual proxy configuration as proxy??.iitd.ac.in:port or IP-address-of-the-proxy-server:port (these parameters can be noted from the web-portal for proxy authentication). Users will be automatically logged out of the proxy server when they disconnect from WiFi.

Eduroam

Print PDF

IITD has become a part of Eduroam, a global Wifi roaming programme across academic campuses, through ERNET, India

Any faculty, staff or student of IITD visiting an academic instituion which is a member of the Eduroam programme anywhere in the world may have unlimited internet access by connecting their laptop or other mobile devices through the secure WiFi SSID called EDUROAM.  They will be authenticated by the WiFi authentication server at IITD.

In a reciprocal arrangement, any academic visitor to IITD from a partner academic institution will be able to connect to our campus-wide WiFi using the EDUROAM SSID and will have unrestricted internet access. They will be authenticated by their home institutions.

EDUROAM is available at several thousand locations in over 60 countries.

All members from IITD can connect to the EDUROAM SSID using the login uid@IITD.AC.IN and their IITD Kerberos password. They have to set their laptop/mobile to use IEEE 802.1x WPA2 Enterprise based encryption for authentication and use the EAP methods EAP-TTLS or EAP-PEAP with MsChapv2 as the inner-tunnel method. Please see IITD Campus Wifi for configuration details. The same settings will work from any EDUROAM enabled location in the world.

Mac, iPhone and iPad users can use the mobileconfig utility available at the CSC website to configure their devices for EDUROAM.

IITD users connected thrugh EDUROAM from within IITD will still have to use the IITD Proxy servers.

Calendar server

Print PDF

 

The Davical based calendar server crashed due to some inconsistencies in upstream package distribution is the source repository and we have not been able to restore the calendar server. The calendar entries are lost (and yes, we are ashamed).

CSC has now decided to shift to the ownCloud calendar server, which is also based on the caldav protocol. The Roundcube webmail interface has been reconfigured to work with ownCloud

Users will need to login to ownCloud (https://owncloud.iitd.ac.in) and create a calendar called defaultcalendar (unless it already exists) to be able to access it from the Roundcube webmail interface. Users can add/configure other calendars in Roundcube from Settings -> Caldav Settings.

Please see the help after logging in to ownCloud (https://owncloud.iitd.ac.in) on how to configure other calendar clients to work with the ownCloud calendar server. Apple (Mac/iPad/iPhone) users can use the mobileconfig utility available at http://www.cc.iitd.ernet.in/CSC/index.php?option=com_content&view=article&id=79.
