Is Linux's "Free Dinner" still eat?
The rise of Linux, full of heart-drunk legend. People have begun to find their financial revenue, and the ratio from the Linux section is getting higher and higher. Free software products are rich, low-cost, open source, freely cut, suitable for customization, these are the current 169% manufacturers' firewall products based on Linux. But this year, SCO sent a letter to 1,500 large companies around the world, and announced that it will mail the Linux business user mail invoice, requiring these companies to pay $ 699 license fee for each Linux server. So-
Regarding the issue of copyright use, I have encountered domestic experts in the beginning of Linux. Today, the network security product market has raised, this problem is again concerned. Previously, the reporter interviewed Fang Zheng, Lenovo, NetScreen, Cisco and other companies used in Linux copyright, and the manufacturers were extremely cautious. On the software copyright use of safety products, most providers do not want to discuss in-depth discussions. Then, use Linux or the operating system based on other copyright, there is no hidden danger for the manufacturer and the user?
Two sounds
Recently, Network Security Vendor Netcom announces that the company's series of security products use a BSD license-based FreeBSD operating system while stopping development products on Linux based on GPL licenses. The person in charge of the company explained that this move is out of copyright considerations. People think that Linux is free, you can get the source code, no copyright can be free to use its software, and be sold as a commodity. In fact, Linux-based firewall, property rights belong to the author's LINUS and related software. GPL license requires vendors to automatically follow the GPL license agreement based on Linux transformed derivatives, that is, the source code must be publicly available. And this is not suitable for the security industry. No user is willing to spend money, bought a firewall, but found that the source code on the Internet is open, can be downloaded for free. Li Yuanyuan, Manager of the China Network Market, further explained that Linux itself is not good, but it is not suitable for the development of safety products. Infringement of copyright, purchase pirated products, facing compensation risk, no quality assurance, security risks, these are Li Yuanyuan summarizes the adverse results of Linux. However, there is also a big man in opposition to this. The discussion of Linux copyright issues is positively responding to the discussion of Linux copyright issues with Linux embedded technology. Li Ling, the company's technical director, believes that Linux's GPL license agreement does not have any potential dangers for users. The GPL is trying to protect the user's rights. Application developers may need to pay attention to the GPL restriction clause, and end users have no reason to worry. Blue Point has two main reasons for Linux: First, for the application, Linux can meet design requirements well; in addition, Linux's market visibility and extensive third-party support are also important factors. Li Ling, a company technical officer of Linux technology, reminded: "Application developers are not operating system developers, should focus on the application." For industry users such as domestic government, finance and other industrial users, from the long run Angle considerations, they generally tend to use domestic security products, which can be certified in some relevant procurement projects in recent years. The government procurement market is expected to have more than 30 billion yuan, Jinshan, China Soft, Zhongke Hongqi and other domestic manufacturers have gained favored. It is exactly the government's respected source of Source Code Open Software Linux Operating Platform Representative, stimulating the enthusiasm of the manufacturer's Linux.
