Prakash Advani, a long-term supporter of Free/Libre and Open Source Software, and earlier head of the network, has argued that GNU/Linux is being increasingly accepted by the corporate world, both as a tool to save money and offer cutting-edge technologies. Advani said that with 50 users, any firm could save considerable sums by using a Linux print-and-file server, as an internet and e-mail server, and also for networking. “It can also be used for web-servers, proxy-servers, internet servers, firewalls, routers, application servers, database servers or fax gateways,” he has said.
