The biggest difference between networks and standings is the characteristics of its own, and a single problem is likely to map a certain link in the network, and even destroy all network operations. Then when the network is especially homes, how should we face it, how should we handle it? Oh, hard way, soft and soft, solutions may involve many aspects, even foreign hardware test tools, but the price ... This article is only widely used in the domestic local area network The built-in network test tools and netizens in the Windows 98 / NT / 2000 operating system explore. First, ping techniques believe that the buddies who have played the network will have a command to "ping". The ping command is a probe tool for the integrated TCP / IP protocol in Windows 95/98 / NT. Everything to apply TCP / IP protocols, whether you are only a family of computers within the interior, office LAN, or campus network, enterprise network or even Internet International Internet, when the client and client are unable When accessing or interviewing or online work, it is recommended that you must first try this command to confirm and exclude problems, sometimes you can work. 1. Since the syntax format of the ping command is a technique, of course, it is necessary to give a brother who can't understand the ping command. The specific syntax format of the ping command: PING destination address [parameter 1] [parameter 2] ... one of the destination addresses refers to the test Computer's IP address or domain name. The main parameters are: A: Analysis of the host address. N: Data: The number of test packages, the default is 4. L: Numerical: The size of the transmit buffer. T: Continue to execute the ping command until the user is terminated by Ctrl C. Other parameters for ping, can be running ping or ping in the MS-DOS prompt? Command to view. 2. The application skills of the ping command uses the PING tool to check the network server and any client's TCP / IP protocol, as long as the IP address of the computer on any of the other computers in the network. For example, if you want to check if the TCP / IP protocol on the HPQW is normal, you can type in Ping 192.192.225.225 in the "Run" subkey under the Start menu.
If the HPQW TCP / IP protocol is working properly, it will display the following information as follows: pinging 192.192.225.225 with 32 bytes of data: reply from 192.192.225.225:Bytes=32 Time = 1ms TTL = 128 reply from 192.192.225.225:bytes=32 time <1ms TTL = 128 Reply from 192.192.225.225:bytes=32 time <1ms TTL = 128 Reply from 192.192.225.225:bytes=32 time <1ms TTL = 128 Ping statistice for 192.192.225.225: Packets: Sent = 4, Received = 4, LOST = 0 (0% Loss) Approximate Round Times in Milli-Seconds: minimum = 0ms, Maximum = 1ms, Average = 0ms or more returns 4 test packets, where bytes = 32 indicates that the data packet size sent in the test is 32 bytes. TIME <10ms represents the time used to round and trip to the opponent, TTL = 128 represents the TTL (TIME TO LIVE) value used in the current test (system) Defaults). If a network problem, as shown below in response to failure information is returned:. Pinging 192.192.225.225 with 32 bytes of data Request timed out Request timed out Request timed out Request timed out Ping statistice for 192.192.225.225:... Packets: Sent = 4, Received = 0, LOST / = 4 (100% Loss), Approximate Round Trip Times In Milli-Seconds Minimum = 0ms, Maximum = 0ms, Average = 0ms Agree, as a network management, take a closer network The cause of the fault and the online node that may have problems. It is recommended to check out from the following aspects: First, see if the TCP / IP protocol has been installed; second, check the NIC installation of the test computer. Whether it is correct and whether it has been connected; three is to look at whether the TCP / IP protocol of the test computer is effectively binding to the NIC (the specific method is to view "Start → Settings → Control Panel → Network"; four is to check Whether the network service function of the Windows NT server has started (can be selected by selecting "Start → Settings → Control Panel → Services", finding "Server" in the dialog that appears, see if "Status" is "already start up"). If the problem is not found through the above four steps, it is recommended that you reinstall and set up the TCP / IP protocol if it is a TCP / IP protocol problem, which is definitely solved. According to the above method, we can also use the ping command to check the working conditions of TCP / IP on any customer's turbulent computer.
For example, we have to check the configuration and work of the TCP / IP protocol on any client "computer room 01", and can directly ping the IP address of the unit on the machine, if the successful information is returned, the IP address configuration is correct. If it fails, the configuration of the IP address should be checked. The following steps can be performed first: first check the entire network, follow the IP address is being used by other users, then look at whether the workstation has been properly connected to the network (there are many cases without landing the network will also appear The situation, this is a low-level error). Finally check the I / 0 address | IRQ value and DMA value of the network card, which conflicts with other devices. The last inspection is very important, and it is often overlooked by many users. Even after the success is successful, this should be checked. Because when the IP address of the PING is successful, only the IP address configuration of this unit is not problematic, but it cannot be explained in full. At this time, although the computer name of this machine can be seen in the "online neighbor", it is impossible to connect with other users. I don't know where the problem is, in fact, the problem is often on the NIC. The above application skills are still focused. The application of the ping command in the LAN, in fact, the ping command is not only widely used in the local area, but also uses it to detect the remote connection of the network in the Internet. Usually, when we encounter two cases, it is necessary to use the PING tool to test the connection between the network. For example, when a website is unacceptable, you can use the ping command to detect. If you are unable to access the homepage of the CCID, you can use the command line of "ping www.ccidnet.com" to test if you return to "pinging ns. Ccidnet.com with 32 bytes of data: ..." Description The other party has been opened, and the opposite is indicated that a fault may occur in a part of the network connection, or the other host is not open. In addition, we can test the connectivity of the network before sending E-mail. Many Internet users often receive information such as "Retund Mail: User Unknown" after sending E-mail, indicating that your email is not sent to the destination. In order to avoid such events again, it is recommended that everyone develops the habit of ping each other mail server addresses before sending E-MAIL. For example, when you send an email to fbk@188.net, type "ping 188.net" to test, if you return to "Bad IP Address Cniti.com" or "Request Times Out", explain the other party The host has not been opened or the network is not connected. At this time, even if the email is sent, the other party cannot be received. Although the ping command is simple, it is actually used, but the flexible use is believed to have an unexpected surprise to your network management career. Second, IPCONFIG / WINIPCFG techniques are different from ping, using IPConfig and WiniPCFG tools to view and modify the configuration of TCP / IP protocol in the network, such as IP address, gateway, subnet mask, etc.. These two tools can be used in Windows 95/98, which is basically the same, just the character form of IPConfig J C DOS, and WiniPCFG is displayed with graphical interface. At the same time, only IPConfig tools running in the DOS mode in Windows NT.
1. The syntax format of the ipconfig command can run in the DOS prompt of Windows 95/98 / NT, and its command format is: ipconfig [/ parameter 1] [/ parameter 2] ... two of the most practical parameters To: All: Displays all the details related to the TCP / IP protocol, including host name, node type, whether IP routing, network card physical address, default gateway, etc. BATCH [Text File Name]: Deposit the results of the test into the specified text file name to view it item by item. Other parameters can be viewed in the "IPConfig /" command at the DOS prompt. IPCONFIG should be a network scouting tool, especially when setting DHCP (Dynamic IP Address Configuration Protocol) in the user's network, allows users to easily understand the actual configuration of IP addresses. If we run "IPConfig / All / Batch Kunpeng.txt" on the computer room 01 client, open the kunpeng.txt file, which will display the contents shown below, which shows the relevant configuration of the TCP / IP protocol. ........................................................................: Ip routing enabled. No wins prony enabled.................................... .......................................... Lease: Lease......................... ........: 2. The application skills of the Winipcfg command is basically the same as IPConfig, but WiniPCFG is more convenient to operate and can be displayed in Windows 32-bit graphics interface. When the user needs to see the configuration of the TCP / IP protocol on any machine, simply select "Start → Run" on Windows 95/98, enter the command "WinipCFG" in the dialog that appears, and the test results will appear. Click the Details button, you can view and change the relevant configuration paradigm of TCP / IP in the subsequent dialog box. When you install multiple network cards on a machine, you can find the physical address of each network card and The binding situation of the agreement is particularly useful to us some at some time. If you want to get more information, click the Details button in the figure, you can see the more comprehensive information in the dialog box.
