About CGI and SSI

CGI and SSI increase the homepage's power of expression and improve its function, but can adversely effect the server's security and balance. With the exception of rental server traders whose selling point is to provide CGI and SSI service, most Internet providers do not offer CGI and SSI service functions because their priority is to provide safe and stable service. Nirai shares this policy. We provide functions created by us for those services which cannot be performed without using CGI and SSI. Currently Nirai only provides only the Access Counter function. Please understand that decision has not yet been made as to which functions will be provided in the future.

Available Software

The Internet software that can be used in Nirai Personal, Economy, Premium, Platinum120 Plans includes the browser software such as Internet Explorer and Netscape Navigator, E-mail software such as Outlook Express and Netscape Messenger (includes News Reader), and FTP Client (such as FFFTP and Fetch). As a rule, other Internet programs that can be used only if the other party has the same software, in particular Network Game and Network Conference software, cannot be used in Nirai. This is due to the presence of a firewall. For more information about the firewall, please refer to information below. With regards to the Nirai Platinum120 global and Business Plans, all Internet applications can be used.

Necessity of a Firewall

The following is a general overview of the firewall system. Originally the Internet was developed by an organization for its own use, without concern for security and quality. The system is essentially the same, but now the Internet is available to people all over the world. Unfortunately there are those people and organizations with Internet access bearing ill will towards others. Therefore, in order to protect yourself from outside attacks , it is necessary to separate the Internet system from the Nirai network. In the case of most dial-up connections, there is little chance of being attacked because the connection to the Internet exists only when the User is online. The first defensive step, and the most effective one, is to set up a firewall between the Internet and the network that needs protection from possible attacks from the outside. (Needless to say it is necessary for everyone to take precautions to protect themselves on the Internet, just as in real life. For example, avoid the excessive downloading of materials, and do not provide personal information or credit card numbers to pages lacking proper security.) Unfortunately one drawback of the firewall is that game software which uses a network cannot be used because the firewall restricts access from the Internet system. However , please understand that a firewall is an indispensable part of measures aimed at maintaining User safety.
