New Software Repository

E-mail Print PDF

CSC has commissioned a new software repositiory installation designed and executed by Phani Mahesh. The repository has the advantage that it uses a caching proxy to cache only those software packages that are needed by users from time to time, rather than mirroring whole sites like Ubuntu, Debian or Gentoo. With this new architecture we have been able to provide links for more than just software. The style of presentation is also different from the usual CSC style of web-pages.

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.

New Disaster Recovery Data Centre

Print PDF

CSC has commissioned a new disaster recovery data centre (DRDC) in the SIT building on September 13, 2014. The DRDC has been built by IBM and can support a total IT load of 60 KW. It has redundant UPS power supplies and precision airconditioners in N+N and N+1 configurations respectively. The DRDC is 2 hr fire rated has been designed for an annualized average Power Usage Effectiveness (PUE) of 1.55. 

CSC has migrated a redundant set of network stack, storage and blade servers to the DRDC, and an active redundant set of fibres from all academic and hostel distribution switches are terminated at the DRDC. The infrastructure blades and the storage servers in the CSC and DRDC have Layer 2 connectivity and all CSC virtual machines can run from either site. CSC can now offer its infrastructure services from either or both the locations.

From now on all CSC infrastructure and ERP data (except Baadal and ACSS data) will be available live in two different locations - CSC and DRDC. Every bit of CSC infrastructure data from now on will be synchronously written in both locations and can be served from either.

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.
