诺顿Ghost克隆参数应用

摘要: 相信Windows 的死机、系统崩溃大家见过了不少。快速重新恢复系统的高招就是使用Ghost程序，但是每次使用Ghost都必须进行选择，太麻烦了。

　　其实，Ghsot有很多参数，巧妙地利用这些参数，并把它们写入MS-DOS批处理软件中，能够给我们备份和恢复系统带来很大的方便。

硬盘分区小技巧

        大家分区的时侯都会输入数字，比如你想得到一个2G的分区你也许会输入2000M或者2048M其实你输入的这些数字所分出来的区在Windows下面都不会被认成整数的2G，而是1.9?G，想要得到Windows下的整数G分区，你必须知道一个公式，通过这个公式算出的值就是被Windows认成整数G的值。
        整数G计算公式：(X－1)*4+1024*X=Y
       其中X就是你想要得到的整数分区的数值，单位是G，Y是你分区时应该输入的数字，单位是M，例如我想得到Windows下的3G整数空间，那么我分区时就应该输入(3－1)*4＋1024*3＝3080，那么我们应该在分区时输入3080作为分区的大小，同理欲分出10G的空间则应该是(10－1)*4＋1024*10＝10276,输入10276将会得到10G的整数空间.

How to configure Vnet/IP network domain on L3SW?

Today,i read the Vnet/IP network building mannual thoroughly.Now make a summary of it.I think it should have several steps to finish the configuration as following:
1.You have to determine what the Vnet domain number,such as the domain number is 6 and 10.That's ok.

2.When we have known the domain number,naturally,we know the ip parameters which will be configured on related interface of L3SW.That's,192.168.134/24 and 192.168.138/24,the default gateway are 192.168.134.253 and 192.168.138.253 respectively.All of these parameters are based on the example of the first step.

3.Making well physical connection prepare.connect any port of L2SW by bus 1, and determine what port we want to use on L3SW,to assume, the port 1 and port 2.That's all right, the next working is going to implement port configuration.

4.Here,maybe you have a question about what's ip address for port 1? Luckly,we have known the default gateway in step 2. Therefor, the port 1 ip address is 192.168.134.253/24,as well as port 2 is 192.168.138.253.

5.The left work is going to configure the L3SW. I believe it is a light carriage on a familiar road for you now.

How to specify the network statement under RIP?

First, take a example in order to illustration. Now we have a router, its ip address i s192.168.1.1/24, then maybe a question asked by you, Why doesn't the network statement under RIP specify192.168.1.0 rather than 192.168.0.0?
RIP comes in two different versions: 1 and 2. Version 1 is a distance vector protocol. Version 2 is a hybrid protocol. RIP v1 uses local broadcasts to share routing information. These updates are periodic in nature, ocurring, by default, every 30 seconds.Both version of RIP used hop count as a metric,which is not always the best metric to use. To prevent packets from circling around a looop forever,both versions of RIP use counting to infinity,placing a hop count limit of 15-any packet that reaches the sixteenth hop will be dropped. Instead of using broadcast, RIPv2 uses multicasts. And to speed up convergence, RIPv2 supports triggered updates . RIP v1 is classful,and RIPv2 is classless.

Do you have a clearly understanding about Classful and Classless concepts ?here,let's go over again.
1.Classful Routing Protocols
A classful routing protocol understands only class subnets.RIPv1 and IGRP are examples. A classful protocol does not send subnet mask information. RIP and IGRP can have subnet masks other than the default, but the subnet mask used must be the same for all subnets of a class address.
2.Classless Routing Protocols
Classless routing protocols do not have any issues accepting routing updates with any bit value for a subnet mask, allowing nonconforming but requieres the configuration of the ip classless command. However, this overrides the calssful protocols' mechanics, Classless protocols include RIPv2,eigrp, ospf,IS-IS,and BGP.

So far as now, i guess you have seen how to specify the network statement under RIP.Let 's have a look at it.For classful protocol, it should be 192.168.1.0,however 192.168.0.0 for classless protocol.
ok, finally,we all see.
