Version 4 (IPv4) is the version most commonly in use. However, there are issues with IPv4, and the Internet Engineering Task Force (IETF) has designated Version 6 (IPv6) to succeed IPv4 as the next-generation protocol for use on the Internet.IPv6 has a number of advantages over IPv4. The following are four important ones:•Large address spaceAn IPv4 address consists of four bytes (32 bits). IPv6 addresses consist of 16 bytes (128 bits). The increase from 32 to 128 bits results in a huge increase in the number of available addresses: 79 billion billion billion times the addresses available in the IPv4—this is about 1038 addresses, or 1030 addresses for each person on the planet.The expanded address space means that IPv6 does not face the address exhaustion problems predicted imminently for IPv4.Furthermore, the availability for so many addresses means that private address spaces are not required, and that addressshortage work-arounds such as Network Address Translation (NAT) can be eliminated. With no private addresses, there need be no hidden networks or hosts, and all devices can be globally reachable. A larger address space also means that features such as multihoming and aggregation are easier to implement.•Support for mobile devicesA special protocol, Mobile IP, is required to support mobility. Mobile IP is not automatic in IPv4, and there are several challengesinvolved in implementing Mobile IP on IPv4 networks. In contrast, Mobile IP was designed into IPv6 from its inception, and is a mandatory feature in a standards-compliant IPv6 protocol stack.•FlexibilityIPv6 includes multiple levels of hierarchy in the address space. This allows for hierarchical allocation of addressing and more efficient route aggregation. It also permits new kinds of addresses not possible in IPv4, such as link- and site-scopedaddressing.•SecurityBecause devices can be globally reachable, end-to-end security can be employed, which is not possible on an internetwork with hidden networks and hosts.Supported standardsThe Brocade vRouter implementation of IPv6 complies with the following standards:•RFC 2460: Internet Protocol, version 6 (IPv6) Specification•RFC 4443: Internet Control Message Protocol (ICMPv6) for the Internet protocol version 6 (IPv6)IPv6 addressingIPv6 addressingIP addresses generally take the following form:x:x:x:x:x:x:x:xwhere x is a 16-bit hexadecimal number; for example:2001:0DB8:0000:0000:51DA:27C0:E4C2:0124Addresses are case-insensitive; for example, the following is equivalent to the example given above:2001:0db8:0000:0000:51da:27c0:E4c2:0124Leading zeros are optional; for example, the following is a valid IPv6 address:2001:DB8:0:0:51DA:27C0:E4C2:124IPv6 addresses often contain many bytes with a value of zero. Successive fields of zeros can be represented by replacing them with a double colon, as in the following:2001:DB8::51DA:27C0:E4C2:124Similarly the following:2001:DB8::124is equivalent to the following:2001:DB8:0:0:0:0:0:0124and this:0:0:0:0:0:0:0:1is equivalent to this:::1The replacement by the double colon may be made only once within an address, as using the double colon more than once can result in ambiguity. For example, the following:2001:DB8::27C0::0124is ambiguous between these three addresses:2001:0DB8:0000:27C0:0000:0000:0000:01242001:0DB8:0000:0000:27C0:0000:0000:01242001:0DB8:0000:0000:0000:27C0:0000:0124IPv6 addresses that are extensions of IPv4 addresses can be written in a mixed notation, where the rightmost four bytes of the IPv6 address are replaced with the four decimal octets of the IPv4 address. In mixed notation, the four hexadecimal bytes are separated by colons and the four decimal octets are separated by dots, as in the following example:2001:db8:0:1::192.168.100.51which is equivalent to2001:db8:0:1::c0a8:6433IPv6 forwarding Special addressesLike IPv4, IPv6 has some special addresses, which are used by convention for special functions. For unicast addresses, these include the following:•The unspecified address. This address is used as a placeholder when no address is available (for example, in an initial DHCP address), or to stand for “any” address. In IPv6, the unspecified address can be represented as either of the following: 0:0:0:0:0:0:0:0::•The localhost (loopback) interface. The loopback interface is a software interface that represents the local device itself. In IPv4, the address 127.0.0.1 is used by convention for the loopback interface. In IPv6, the loopback interface can be represented by either of the following:0:0:0:0:0:0:0:1::1The IPv6 address architecture is quite rich, and includes types of addressing unavailable in IPv4, such as unicast and multicast scoped addresses, aggregatable global addresses, and anycast addresses. Multicast broadcast addresses do not exist in IPv6. For more information about the IPv6 address architecture, consult RFC 4291, IP Version 6 Addressing Architecture.IPv6 autoconfigurationIPv6 supports two mechanisms for automatically configuring devices with IP addresses: stateful and stateless. Both are supported in the Brocade 5600 vRouter.In stateful configuration, addressing and service information is distributed by a protocol (DHCPv6) in the same way that the Dynamic Host Configuration Protocol (DHCP) distributes information for IPv4. This information is “stateful” in that both the DHCP server and the DHCP client must maintain the addressing and service information.Stateless configuration uses the Stateless Address Autoconfiguration (SLAAC) protocol, which is a component of the larger Neighbor Discovery (ND) protocol. SLAAC has a host component and a router component.In the host component of SLAAC, the IPv6 system constructs its own unicast global address from the system’s network prefix together with its Ethernet media access control (MAC) address. The device proposes this address to the network, without requiring approval from a server such as a DHCP server. The combination of network prefix and MAC address is assumed to be unique. Stateless autoconfiguration is performed by default by most IPv6 systems, including the Brocade vRouter.In the router component of SLAAC, routers respond to Router Solicitation (RS) packets from hosts with network prefix information in the form of Router Advertisement (RA) packet. Hosts receive these advertisements and use them to form globally unique IPv6 addresses. The RS and RA packets also provide the router discovery function, allowing hosts to locate routers that are configured to serve as default routers. The Brocade vRouter fully supports router-side SLAAC and router discovery, including all required configurable parameters. The ND protocol and the router discovery function are specified in RFC 4861. IPv6 Stateless Address Autoconfiguration is described in RFC 4862.IPv6 forwardingOn the Brocade vRouter, IPv6 forwarding is enabled by default. If you want to disable IPv6 forwarding, use the following command in configuration mode: set system ipv6 disable-forwarding. This command is described in Brocade Vyatta Network OS Basic System Configuration Guide.IPv6 neighbor discoveryIPv6 neighbor discoveryIPv6 Neighbor Discovery (ND) provides a layer 3 to layer 2 address resolution mechanism for IPv6 similar to the way that Address Resolution Protocol (ARP) provides for layer 3 to layer 2 address resolution for IPv4.ND resolution is carried out in both the data plane and the control plane; however, it is primarily carried out in the data plane. Note that ND caches in the control plane and data plane are no longer synchronized because entries in the two caches are managed independently. The data plane cache contains entries for both forwarded and locally terminated traffic. The control plane maintains cache entries only for destinations with which the local stack of the control plane communicates.The advantages of implementing the ND protocol in the data plane are as follows:•Avoids bandwidth issues in deployments with distributed data planes, because ND resolution can be performed locally rather than on a centralized controller.•Improves performance because ND does not need to send all ND packets to the control plane.•Protects against scanning DOS attacks due to resolution throttling.Commands for IPv6In addition to the general IPv6 information found in this document, information specific to major functions of the Brocade vRouter are found within the applicable documents for that function; for example, the following:•Commands for enabling and disabling IPv6 on the system are located in Brocade Vyatta Network OS Basic System Configuration Guide.•Commands for configuring IPv6 on a given interface are located in the guide that describes the interface. For example, commands for configuring IPv6 on an Ethernet interface are located in Brocade Vyatta Network OS LAN InterfacesConfiguration Guide.•Static IPv6 routing information can be found in Brocade Vyatta Network OS Basic Routing Configuration Guide.•RIPng-related dynamic IPv6 routing information can be found in Brocade Vyatta Network OS RIPng Configuration Guide.•BGP-related dynamic IPv6 routing information can be found in Brocade Vyatta Network OS BGP Configuration Guide.•DHCPv6-related information can be found in Brocade Vyatta Network OS Services Configuration Guide as well as Brocade Vyatta Network OS LAN Interfaces Configuration Guide.•Tunneling IPv6 over IPv4 is discussed in Brocade Vyatta Network OS Tunnels Configuration Guide.•Multicast routing for IPv6 is discussed in Brocade Vyatta Network OS IGMP and MLD Configuration Guide.IPv6 Configuration Examples•Configure an IPv6 address on an interface (15)•Verify IPv6 support (16)•Display the IPv6 routing table (17)•Confirm connectivity (17)•Display IPv6 Neighbor Discovery (ND) cache (17)•Clear ND cache (18)Configure an IPv6 address on an interfaceFigure 1 shows a simple network with two IPv6 nodes.FIGURE 1 IPv6 address on an interfaceIPv6 addresses are configured on data-plane interfaces in the same way that IPv4 addresses are.

手机设置
诺基亚C6的WIFI上网设置诺基亚C6的WIFI上网设置大多数机油应该很是清楚了,但还是有菜菜鸟、小菜鸟、新童鞋不是很懂。
写来给需要的机油看看。
依次点开手机的以下菜单或选项:主菜单——设置——连接功能——承载方式——互联网——(无线路由的名称)——选项——编辑——选项——高级设置——IPv4设置“IPv4设置”这部分最重要!手机IP地址:设置为与你的无线路由一个IP段的地址,如:192.168.1.177子网掩码:255.255.255.0默认网关:192.168.1.1DNS地址:和你自用的电脑上的设置一样,也可以打开无线路由查看。
(注意:进入无线路由时,会发现有两个DNS地址,后面的为主地址,前面的是次地址。
别搞混啦~)“IPv6设置”:不用管“代理服务器地址”:不用管“代理端口号码”:不用管——不出意外的话,这样C6就可以顺利利用WIFI上网了。
补充:如何进路由器?1、打开IE浏览器2、在地址栏输入“192.168.1.1”(具体看路由器说明书或背后的铭牌,上面写得很清楚),回车!3、提示你输入账号、密码,一般是admin、admin(具体也是看路由器说明书或背后的铭牌,上面写得很清楚)。
就可以进入到路由器了。
4、进入路由器后,可以对路由器进行设置,也可以恢复其出厂设置,重启路由器…… 补充:连接无线网出现“服务器名称无效”问题个人发现解决本人刚买C6的时候用WIFI连接家里的路由器可是连接上了就是进不了网出现“服务器名称无效” 后来我看了很多这样的帖子。
按上面的做都没有用后来自己就发现了其实不是手机的问题。
是电脑没设置好。
我的是这样的问题先是在电脑上“宽带连接”点进去然后点“属性”然后会看到有个“高级”的点进去会看到“Internet 连接共享” 下面会有个小框勾起来就行了我的手机是这样的不知道你们行不行配置“远程驱动器",让c6-01无线访问电脑硬盘尤如访问自己的内存卡N8的远程驱动器功能使她可以不借助第三方软件,实现无线方式访问远程电脑硬盘(实际为硬盘目录)。

实训二搭建基础结构(infrastructure)模式无线网络
搭建基础结构(Infrastructure)模式无线网络实验名称:搭建基础结构(Infrastructure)模式无线网络。
实验目的:掌握基础结构模式无线网络的概念及搭建方法。
背景描述:假设你供职的公司租用一个新房间作为会议室,并且希望在会议室中能上网。
你作为公司的网络管理员上司建议说:如果用有线上网的话。
需要在会议室中穿墙凿洞,重新布线,而且开会是也不能保证大家都有线上网,因此应该在会议室里实现无线上网,使大家在开会时的交流及信息的互通更为方便。
公司采纳了你的意见用AP设备在会议室搭建了无线网络。
受到大家的热烈欢迎。
你的能力也得到了上司的认可。
需求分析:需求1.新会议室能够上网分析1. 单就上网这个需求来讲,可以有无线与有线两种选择。
有线网络可采用交换机、路由器等常见网络设备组网,无线网络则可采用无线AP来搭建,采用哪种方式更好呢?需求2.在不破坏环境的前提下,应尽可能保证参会人员能接入网络。
分析2.有线网络的使用,布线是关键,并且需要一定的部署时间;无线网络方便快捷,而且部署灵活,适合移动办公的场所。
实验拓扑:如图所示的网络拓扑结构就是公司会议室中通过无线AP,实现几台计算机之间无线通信的工作场景,通过无线AP、无线网卡实现基础结构模式无线网络通信。
实验设备:无线接入设备AP(一台)、无线网卡(2块)。
实验原理:基础结构模式无线网络是最为常见的一种无线网络部署方式,无线客户端通过无线接入点接入网络,任意无线客户端之间的通信都需要无线接入点进行转发。
与自组网络模式无线网络相比,基础结构模式无线网络覆盖范围更广,网络可控性和可伸缩性更好。
实验步骤:(1).配置测试计算机STA1,与无线接入设备AP(RG—WG54P)相连接。
一)用一根直线通线将测试计算机STA1与无线接入设备AP(RG-WG54P)供电模块的Network口相连。
二)在Windows控制面板中,打开网络连接页面。
三)配置测试计算机STA1本地连接的TCP/IP,单击“确定”按钮完成设置,如图所示。

错误原因:
在tnsnames.ora文件中,无法找到连接字符串中网络服务名到连接描 述符的映射关系。 检查在%ORACLE_HOME%\network\admin目录中是否存在 tnsnames.ora文件,或是否已经损坏 在tnsnames.ora文件中,检查网络服务名到连接描述符的映射是否正 确 检查同一目录中,是否存在sqlnet.sql 如果网络中使用了域名,检查sqlne.orat中是否定义了 names_default_domain参数
例:export tns_admin=~/network(Linux)

监听程序
服务器端进行监听 监听程序(listener)用于接收客户端的连接请求 网络配置文件listener.ora中存放监听程序的信息
38
建立主机名称解析环境
以hosts文件为例说明 打开目录C:\WINDOWS\system32\drivers\etc下的文件 hosts,进行如下修改
# IP Address 127.0.0.1 192.168.100.10 host name localhost sales-server alias
检查客户端tnanames.ora中的server参数的设置是否正确 在服务器端使用lsnrctl工具中的service目录来查看已经注册到 监听器的服务器类型 确定数据库实例已经启动
44
例子
40
连接测试
在客户端测试网络连接
tnsping工具 语法:tnsping 网络服务名 [count]
例子: c:\>tnsping orcl
使用Oracle Net Configuration Assistant进行测试
41
故障排除(1)
ORA-12154:TNS无法解析服务名
37
配置主机命名方式为首选方式
方法1:使用Net Manager进行配置 方法2:使用Oracle Net Configuration Assistant进行配置 方法3:修改sqlnet.ora文件为
SQLNET.AUTHENTICATION_SERVICES= (NTS) NAMES.DIRECTORY_PATH= (HOSTNAME, TNSNAMES, ONAME)
d:\>lsnrctl stop(关闭) d:\>lsnrctl start(启动) d:\>lsnrctl status(查看状态)
14
配置客户端
客户端网络配置的主要任务
为客户端选择所使用的命名方式 建立所选的连接标识符(网络服务名)到连接描述符的映射 关系 tnsnames.ora:配置网络服务名 sqlnet.ora:配置客户端的命名方式
位置:%ORACLE_HOME%\network\admin\listener.ora
配置文件listener.ora的方法
直接编辑文件listener.ora 使用Net Manager或Oracle Net Configuration Assistant进行配置
配置完监听程序后,要重新启动 OracleOraDb10g_home1TNSListener服务
18
例子
19
配置客户端的命名方式
命名方式
客户端应用程序将连接标识符转化为连接描述符的一种名称 解析方法 本地命名方式:TNSNAMES 主机命名方式:HOSTNAME 目录命名方式(需要目录服务器):ONAMES
常用的命名方式
20
本地命名方式
将连接描述符到连接标识符的映射保存在tnsnames.ora 文件中 需要每个客户端都保留一份tnsnames.ora配置文件 优点
Oracle 8或更早版本
在listener.ora文件中,在SID_LIST_<listener_name>代码中添 加GLOBAL_DBNAME参数。
36
例子
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME=) (SID_NAME = SALES) (ORACLE_HOME = D:\oracle\8.0.5) ) )
提供了更为直接的名称解析方式,不依赖于任何其他服务 对网络协议基本上没有限制,可以使用Oracle支持的所有网 络协议 可以利用图形界面进行配置 配置本地命名方式为首选方式 配置网络服务名
21
配置步骤
配置本地命名方式为首选方式(1)
利用Oracle Net Configuration Assistant进行配置(1)
用ping命令测试配置
ping
39
连接到数据库
语法
SQL> conn username/password@global_database_name SQL> conn username/password@ SQL> conn username/password@sales(客户机和服务器在同 一个域时)
连接标识符(connect identifier)
连接描述符(connect descriptor)
网络服务名=主机字符串=连接标识符
17
连接标识符 ORCL = 连接描述符 (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.10)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) )

主机命名方式(1)
比本地命名方式更简单 客户端在连接字符串中使用目标数据库服务器的全局 数据库名,而不是连接标识符 通过DNS或本地的hosts文件将全局数据库名解析为数 据库服务器的IP地址 优点
配置步骤
35
配置监听器监听全局数据库名
Oracle 8i以后的数据库
当满足如下要求时,数据库可以自动找到监听器,并向监听 器进行注册(动态注册)
监听器的默认名称为listener,并且监听TCP/IP协议地址和1521端口 监听器具有非默认的配置,但是对数据库的初始化参数local_listener 进行了正确配置

概述 配置监听程序 配置客户端 连接测试和故障排除

概述
建立了Oracle数据库后,为了使客户程序可以访问该数 据库,首先需要在服务器端配置监听程序和网络服务 名。
网络配置文件的默认位置为: %ORACLE_HOME%\network\admin,其中 ORACLE_HOME = D:\oracle\product\10.2.0\db_1 设置环境变量tns_admin可以修改网络配置文件的位置
解决方法:
42
故障排除(2)
ORA-12224:TNS:没有监听器
用lsnrctl status工具检查监听器是否运行 如果运行,在客户端检查tnsnames.ora文件,确定连接描述符 中的IP地址、端器进程不能解析在连接描述符 中给出的service_name
只需最少的用户网络配置工作 不需要使用本地名称配置文件(tnnnames.ora) 不需要理解连接标识符、连接描述符等基本概念
34
主机命名方式(2)
缺点
客户端只能使用TCP/IP协议进行连接 客户端至少具有一种IP地址解析机制,如DNS,或本地的 hosts文件 不能使用Oracle网络服务中高级服务,如Oracle连接管理器中 所提供的功能。 对监听器有特殊的要求 配置监听器监听全局数据库名(服务器) 将主机命名方式配置为首选方式(客户端) 建立主机名称解析环境(客户端)
