Ramakrishna Mission Vivekananda Educatinal and Research Institute, Belur Main Campus at Belur Math, Howrah, West Bengal, has campus wide network which caters to IT needs of all the departments and the administrative building. There are eight departments in Belur Campus, computer science, physics, mathematics, sanskrit, indian spiritual heritage, sports science and yoga. Currently the number of computers that are using campus wide services is around two hundred and growing. The university runs its own web server (apache, drupal, wordpress), mail transport server (exim), mail exchange server (dovecot), web-mail application (sogo), our own domain name server (bind), both external and internal, dhcp server for dynamic configuration of clients (isc-dhcp-server), masquerading firewall (shorewall), transparent web proxy (squid), web-site blocking (squidguard), web content filtering (dansguardian), light directory service (openldap), time server (ntpd), debian software archive (apt-cacher-ng), instant messaging (ejabber). All these are open source software based on linux.
The university shares its pool of IP addresses with the departments so that the departments can have their own fully function Internet server accessible from Internet to the world. The deparments which have Internet servers are computer science, mathematics, physics, sanskrit, Indian heritage. Library and computer centre also have servers accessible from Internet. These computers have the minimum basic services — their own web servers (apache) and mail servers (exim4) — installed by us, and then the departments are free to add their own user and other services. Along with this we also host websites for Narendrapur campus, and some sister institutions like, Ramakrishna Mission Shilpayatana, Ramakrishna Mission Shilpavidyalaya, Saradapitha, and Ramakrishna Math Veda Vidyalaya.
