spiceworks怎样创建网络平台？

局域网中有一台机器只能发送数据包,而不能收到数据包,上不了网了怎么办?

百分之百是你网线和网卡之间或者网线与路由器（交换机）之间的连接问题，也就是接触问题。

网线中8根线，实际只用到4根线，1.2.3和6。

一对是发送，一对是接收，只要有一对线通，网卡和交换机的灯就会亮。

但数据是没法传输的。

你把网线的水晶头重新做一下，然后用东西把网卡插口里面的针夸一夸。

什么时候能PING通网关，就行了。

IE能打开第一页，是因为第一页在你的缓存里面的。

所以不管网络通不通都能打开。

你按我说的试试吧，我们整天给客户维护网络，这种现象太常见了。

xenserver对xen做过哪些优化

这些都是虚拟化的相关产品．xen是一个Hypervisor, 所谓的vmm(virtual machine manager)管理程序，是硬件虚拟化的众多技术之一，其目的就是为了让多个操作系统同时运行在一台主机设备．我们可以将上面描述的环境(架构)叫做云计算中的iaas. 可以使共有云,或者私有云. Robert P. Goldberg 将Hypervisor分为2种类型: type1: 例如有Citrix XenServer, VMware ESX/ESXi, and Microsoft Hyper-V (vm运行在硬件上的第二层) type2: KVM and VirtualBox are examples of Type 2 hypervisors. 这里我认为vmware workstation, fusion 也应该属于type2. (vm运行在硬件上的第三层) 至于xen我认为也应该属于type1, 因为xen server 和 xcp都是基于xen衍生过来, 而 xen仅仅是一个简单的Hypervisor, 而 citrix xen server , xcp 是一个hypervisor + api + tools 的套装. 下面是网友针对xen,xenserver,xcp的一些总结,非常精辟和准确. said by Scott Alan Miller munity.spiceworks ic/131849-xen-vs-xenserver-vs-xcp Xen: The open source,pletely free granddaddy of the Xen family (which at one time had many children, most of whom are now gone.) Xen is different from all of petitors in that it is a hypervisor ONLY and not a virtualization ecosystem (no management console, no extra features, no nothing.) It’s just a tiny little hypervisor. This is confusing because we lump Xen with HyperV, for example, but it is not an apples to parison. Xen is like the hypervisor inside HyperV that no one even knows the name of. XenServer: The mercial virtualization suite built on technologies derived from Xen. XenServer is an “older” version of Xen with some features removed and other featurs hidden behind “add ons.” So XenServer is far less functional than Xen and is pletely free (it can be, but many features are not.) XenServer is a full suite with all of the nice console and tools, APIs, etc. Much more user friendly than Xen and requires no core OS knowledge to get it working unlike Xen that requires you to really know the Dom0 environment well. XCP: Xen Cloud Platform. XCP is a full virtualization suite based on Xen. It uses real Xen bines in all of the ponents needed to be a full suite just like XenServer, vSphere and HyperV. It is open source es from the Xen people. Today, when people talk about Xen, they mostly talk about XCP as XCP is the apple to apple with the other products and not just the hypervisor. You lose no functionality going with XCP over Xen on its own but it is far easier. XCP is designed to be interoperable with most, if not all, APIs from XenServer so that they can share tools giving XCP a lot of important options.

怎样创建网络平台？

1.网络管理平台，又叫网络运维系统。

通过该win7系统可以实时获取网络拓扑信息和网络设备的配置、性能信息，如果设备出现异常会通过各种图表进行显示，同时还可以根据阀值进行报警提示。

这样一来网络性能指标超过阀值时管理员就会知道，通过调试可以避免严重的网络故障发生。

如果网络故障已发生了，也可以通过网络管理平台淸晰地找到故障点和故障原因。

2.搭建网络管理平台需要在网络管理服务器上安装管理平台软件，并在所有被监控的设备上运行SNMP协议。

搭建网络管理平台可以按照下图所示的拓扑图实施。

3.目前用得比较多的网络管理平台有Spiceworks、WhatsUp Gold、HP Open View, IBM Tivoli Net View,除此之外还有很多类似软件，但是大部分软件在使用上都大同小异。
