<急>TCP作業 utility netstat

題目

Use the utility netstat to show the contents of routing table for your computer. The example command usage is shown as the following (under the DOS prompt 命令提示文字):

>netstat –rn

Route Table

========================================================================

Interface List

0x1 ........................... MS TCP Loopback interface

0x2 ...00 13 d3 a6 c5 57 ...... Realtek RTL8169/8110 Family Gigabit Ethernet NIC

- Packet Scheduler Miniport

========================================================================

========================================================================

Active Routes:

Network Destination Netmask Gateway Interface Metric

0.0.0.0 0.0.0.0 163.13.21.254 163.13.21.124 20

127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1

163.13.21.0 255.255.255.0 163.13.21.124 163.13.21.124 20

163.13.21.124 255.255.255.255 127.0.0.1 127.0.0.1 20

163.13.255.255 255.255.255.255 163.13.21.124 163.13.21.124 20

224.0.0.0 240.0.0.0 163.13.21.124 163.13.21.124 20

255.255.255.255 255.255.255.255 163.13.21.124 163.13.21.124 1

Default Gateway: 163.13.21.254

========================================================================

Persistent Routes:

None

From the messages shown above, deduce the configuration of your computer systems that construct the networks. (as depicted in Fig. 6.19 of page. 150.). you should find out more link information (such as Ethernet Hardware address, IP address, Mask …) about your network by using the utilities from the operating systems.

1.請以英文作答

2.請翻譯你寫下的英文答案

3.以中文解釋題目涵義

(由於問題複雜度偏高~回答者若能清楚回應~解答案正確~將另行再給其他額度點數)

感謝囉~

Update:

如果可以最好!因為我不太懂題目意思!

使用的課本是TCP/IP PROTOCOL SUITE (Third Edition版)作者Forouzan

謝謝唷

Update 2:

哇塞~謝謝囉..

TO:小NO

我想...

妳來亂ㄉ~噗..

Update 3:

TO:linchi99

不知道你會不會用 RFCs that define classless addressing.

這是我的另一個發問題啦^^

雖然今晚前就要交ㄌ..

呵..謝謝囉

    1.要畫圖表示嗎?

    2.上課用哪本書?

    2007-04-06 16:51:25 補充:

    題目:依據netstat –rn 所得的routing table 資訊描述出網路結構,並寫出相關資訊如mac address/ip address/mask address –etc.)

    Ans:(問題是否要敘述,出的不清楚,只好詳述)

    我無權限在此畫圖表式,只好用數字串圖。

    依照routing table 畫出網路拓樸及描素網路結構相關資訊

    [ PC ]i(163.13.21.124)----n(163.13.21.0)----g(163.13.21.254){R}

    (1)The first line of this routing table is the default route. The Gateway Address is the address of a router with an IP address of 163.13.21.254, and it is on the network connected to the interface with the address 163.13.21.124.

    (2)The second line is the loopback route. The address of 127.0.0.1 in the Gateway and Interface is a special value that refers to the local host.

    (3)The third line defines the range of addresses on the local network segment. This shows that any address in the 163.13.21.0 Class B network should be found on the network segment connected to the interface with the address 163.13.21.124

    (4)The fourth line is how a Microsoft routing table defines that 163.13.21.124 is an address for the local host. The 255.255.255.255 netmask identifies that this route applies to only to packets addressed to the single address 163.13.21.124. The 127.0.0.1 Gateway and Interface addresses pass all packets for this address to the local host.

    (5)The fifth entry lists the announce address for the local network. This is another entry that is automatically added when an interface on a Windows TCP/IP system is assigned an IP address.

    (6)The sixth line is the multi-cast address. This route is for special applications that broadcast information to more than one destination

    (7)The seventh line is another line that is unique to Microsoft routing tables

    (8)The Ethernet Hardware address of this machine is 00 13 d3 a6 c5 57

    ──1. 內容超過中文貼不進了 ,自己翻吧,有問題再貼───

    ------2. Routin table 數字要核對,看的眼都花了。

    ------3. 英文部分自己可刪成簡答。
