一、天文大厦三楼无线网络开通

                                                           
                                                        
                                                        近年来，在我台每年都要举办几次国际和国内学术会议，为了更好提供网络服务，满足科研活动需要。经过近半年对无线网络产品性能及安全性的调研及测试，最近我们已在天文大厦三楼铺设了无线网络，目前无线信号可覆盖二至四楼，并设置了两个无线信号（SSID）：

                                                            SHAO:
                                                        提供台内职工及学生访问内网及外网，采用计算机无线网卡地址
                                                        + 密码的方式进行身份认证和访问控制；

                                                           
                                                        
                                                        
                                                        SHAO-guest
                                                        :
                                                        
                                                        提供访客，它采用二种方式进行访问控制：

                                                        
                                                        
                                                              方法一、采用计算机无线网卡地址+密码，可访问互联网，但不能访问台内网信息，适合于在台一个月以上的访客
                                                        ；

      方法二、只需输入SSID密码，只能通过浏览器访问互联网，适合于在台逗留几天的访客。

                                                         

                                                        
                                                        
                                                         SHAO的密码为shao64386191, 
                                                        SHAO-GUEST的密码为shao02164386191

                                                         需要使用无线网络的用户可将你的计算机无线网卡地址邮件给
                                                        我们。

                                                         二、下一代互联网IPv6的开通

                                                            
                                                        
                                                        
                                                        
                                                        2007年我台已开通了IPv6网络，当时主要用于我们与上海超级计算中心的数据传输，且只能采用IPv6地址访问。为了更好地利用IPv6的网络资源，
                                                        现在台局域网内任何一台支持IPv6协议的联网计算机通过访问IPv6网站，启IPv6的具体方法如下：

                                                            
                                                        
                                                        
                                                        1、在winxp系统下，通过“开始->运行-->输入cmd”，在命令提示符窗口，输入：ipv6
                                                        install   即可

                                                            
                                                        
                                                        
                                                        2、在linux系统下，输入modprobe
                                                        ipv6

                                                            
                                                        
                                                        
                                                        3、Win7、Vista系统和MacOs系统默认情况下是启用IPv6

                                                           
                                                        
                                                        如果能浏览器
                                                        
                                                        http://ipv6.google.com 网页，或http://www.cstnet.cn
                                                        网页的左上角显示IPv6的地址，说明你的机器已启用了IPv6。

   

                                                           
                                                        
                                                        
                                                         IPv6网站的资源科访问：http://ipv6.dlut.edu.cn/

                                                         三、第三个C类的IP地址开通

                                                            
                                                        
                                                        
                                                        
                                                        
目前我台原有的2个C类（202.127.29.0～202.127.29.255,202.127.24.0～202.127.29.254）IP地址已基本分配完，现已开始使用新申请的一个C地址（119.78.226.0～119.78.226.255），并开放了该网段对内网和ARP系统的访问。

                                                        有问题可随时邮件或电话给我们。
