New Software Repository

E-mail Print PDF

CSC has commissioned a new software repositiory 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, Centos, 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.

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 ( 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 ( 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
