Q: How to build a simple LAN? A: The easiest way to form a local area is that each machine is a single network card, then there is one or more hubs, which can choose a hub (preferably 10 / 100m adaptive) as the main hub according to the actual machine release. Then connected to the primary hub in UPLINK, so that the level of control level is connected, and the hub-between level is generally not exceeding 3 floors. Then all machine IP addresses are set to the same network segment, that is, the top three of IP is the same, such as 192.168.1.1 (x, x between 1 to 254 integers), subnet mask use 255.255.255.0, a local area network During it, visit the "online neighbor". -------------------------------------------------- ------------------------------------
Q: How should Outlook Express send and receive emails in the LAN? A: Email transceivers such as OE in the LAN also can also be accessed through the proxy server, just no longer use the original single dial-up network settings. Moreover, with respect to the proxy server settings of other software, the server settings of the mail software are more special, and the type of proxy server must be a SOCKS4 or SOCKS5 server. Suppose the address of the proxy server used is: 202.100.1.1, the user's mail address is: abcd@163.com, then the installation method of the proxy server in OE is: Open OE, select the menu "Tool → Account". Select the "Mail" tab in the "Internet Account", then select the account you want to set in the account list, click the "Properties" button. In the Properties window, select the Server tab, enter the address of the proxy server in the message server address (eg 202.100.1.1), and press the name rules of "User Name # Mail Real True Address" in the account Enter "ABCD # pop3.163.com", click "OK" to send and receive mail in the proxy server. -------------------------------------------------- -------------------------------------
Q: Why can I access the server or access the Internet, but I can't access other workstations? A: First, if you use WINS resolution, it may be improper WINS server address; then check the gateway settings. If the two parties are divided into different subnets, the gateway settings are incorrect, then other workstations; The code setting is incorrect can also cause this issue. -------------------------------------------------- -------------------------------------
Q: Why can't you see someone else's machine under Windows 98, but you can't read the data on the computer? A: First, you must set the resource sharing. Select "Network → Configuration → File and Print Sharing", tick the two options and determine, after the installation is successful, "Configuration" will appear in "Configuration" option. In addition, check all the installed protocols to bind the "files on the Microsoft network and printer sharing". Select the protocol in Configuration, such as the TCP / IP Protocol, click the "Properties" button to ensure that the "Microsoft Network" on the Microsoft Network "," Microsoft Network User "is already ticking before the binding. -------------------------------------------------- ------------------------------------- q: Why is it broken when using ADSL to access the Internet? Flow phenomenon? A: First make sure the phone must not be placed next to ADSL Modem, because the phone will automatically find the network every few minutes, and the powerful electromagnetic wave interference is sufficient to cause the ADSL Modem to break. At the same time, try to control the number of telephone secondary machines, but also to reduce interference from the line. In addition, Windows 98 itself is also one of the culprits. You can resolve the following two patchs: Windows 98se version of the patch, Windows 98 dial-up network 1.3 upgrade 1.4 patch. It is most convenient if you can use Windows Update feature. The firewall, shared Internet access server software, online acceleration software, etc. also have the possibility of discharging, and there is an impact of the test judgment. -------------------------------------------------- -------------------------------------
Q: How should I choose ADSL virtual dial-up software? A: ADSL uses PPPoE (Point-to-Point Protocol over Ethernet, Point-to-Point Protocol) Virtual Dial Software, and these virtual dial-up software have their own disadvantages. Under Windows XP, the PPPoE dial-up software is selected, and after multi-party testing, the use of the own virtual dial-up software is relatively small; stability is relatively improved. If you are using Windows 9X / ME, you can choose Enternet, Winpoet, and RaspppoE. Where ENTERNET is now a commonly used, the Enternet 300 applies to Windows 9X; 500 for Windows 2000 / XP. If there is a problem, you can try to exchange other virtual dial-up software. -------------------------------------------------- -------------------------------------
Q: How to use ADSL sharing Internet? A: This is still shared as an example of 4 machines. If your ADSL MODEM supports routing, set the route mode, connect the ADSL MODEM to the Hub, the other 4 is connected to the same hub, then set the gateway, DNS is the IP of the ADSL Modem. If you do not support routing, then have a host dual network card, one card pick ADSL MODEM, one card pick HUB, other machines are connected to one HUB, assume that the host's IP is 192.168.1.2 (x , X takes 2 to 254 integers), gateways and DNS are playing 192.168.1.1, so that the client is set, the main unit can be used, the host can use the gateway agent or proxy server agent, the gateway agent is the simplest. Windows itself's ICS (Internet Connection Sharing) (machine is 2K or XP), set to, right-click your ADSLL dial-Property - Advanced - Allow other network users to share this connection, tick, choose HUB below Hub The name of the NIC, is determined. Note that at this time, you can change the network card address of Hub into 192.168.0.1, you have to change the same network segment with other machines, such as 192.168.1.1, then another NIC IP is set to the ADSL Modem's same network segment ( If you won't be, it will not be set, not a key, just slow a little bit when starting, not large). You can use other software, such as Sygate, Wingate, WinRoute, basically install software, other client settings, and settings like ICS, you can also use the proxy server agent, proxy server agent to specifically set a proxy The port is good, such as the HTTP agent (most 8080), SOCKS (more 1080), etc., the proxy server agent can use the cache, if many people are on the same website, the people behind will come quickly, because the first person Some pictures such as photos have been read, and no need to connect to the remote host. -------------------------------------------------- ------------------------------------- q: Why ADSL's download speed always does not meet Claim? A: The problem of the rate unit. Name 56K MODEM download is 5-6K. The 56K unit is bit, while the rate at which the download is displayed by Byte. 1BYTE = 8bit. So when downloading is 200KB, it has already reached 1.6Mbit, which is already quite fast. Due to many reasons such as server and client hard disk read and write speed, local download speeds cannot play the greatest capacity of ADSL2-8Mbit / s. -------------------------------------------------- ------------------------------------- MODEM Internet Questions ---------- -------------------------------------------------- ---------------------------
Q: No Dial Tone A: Determines the modem driver correctly; your telephone line is not connected to Modem, you should insert the phone line on the "line" mouth of Modem; set the "Dial Network" setting in the system The options of "waiting for dial tone before dial" are not "selected" (not tick) ----------------------------- -------------------------------------------------- -------- Q: Tip said that the computer you call does not respond A: This situation is due to the performance and quality of the MODEM or telephone line you use; related questions: This problem may result in additional A phenomenon, in the terminal window (black window) appearing after the dial of Windows95 / 98, does not show characters or a lot of garbled, is also the reason. -------------------------------------------------- -----------------------------------
Q: After the dial, the rate is found to be 100 or more A: Mainly not properly installed; but in actually the rate is the same ------------------------------------------------------ -------------------------------------------------- ---------------------
Q: I am online when I go online A: When the phone line is not good or the modem quality will cause the broken line ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ -------------------------------------------------- -------------
Q: How to support multi MODEM sharing Internet? A: After the RAS service is installed in NT, 2000, XP, 2003, select the Add Modem to "Control Panel" → "Modem", the system will automatically search for the COM port, if there is MODEM to automatically add, then in the dial-up network Newly built a dial, after the multi-link is dial, Windows NT will connect several modems to obtain a common bandwidth, then the total bandwidth cannot be greater than 115200 bps. 95/98 / me does not support this function
-------------------------------------------------- ------------------------------------- ADSL Internet Questions ---------- -------------------------------------------------- ---------------------------
Q: Why does the actual rate of ADSL do not have the theoretical value? A: This is not the problem of ADSL itself, but the current internet export bandwidth is more narrow. In addition, the telecommunications network is generally limited, its propaganda is only theoretical speed ----------- -------------------------------------------------- ----------------------------
Q, network card and ADSL MODEM unable to connect A, first check if the network cable is loose, the crystal head is good, etc. .0.0.1), but did not ping ADSL MODEM. For this problem, only by replacing the NIC; or change the network card to a slot. -------------------------------------------------- ----------------------------------- q, unable to perform virtual dial-up connections. A, more than the system TCP / IP protocol is damaged, delete the TCP / IP protocol and reinstall it. In WIN98 recommended with ENTERNET300 dial-up software, use RaspppoE dial-up software in Win2000, recommended with your own PPPoE dial-up software; PPPoE dial function, etc. -------------------------------------------------- -----------------------------------
Q: The data cannot be transmitted normally, often "disclosing" phenomenon. A: The quality of the network card directly affects the quality of transmission, it is recommended to use a good quality NIC installation. Make sure the temperature of the ADSL Modem is not too high. If there are no problems above, there is no problem or reinstall the system or reload IE. -------------------------------------------------- -------------------------------------
Q: When there is no authorization data transmission, the ADSL MODEM's DATA light is not flashing A: Determines that P2P software is installed in the system, it is recommended to install firewall software
Q: After installing the network card, the start speed of the machine is significantly slowed. A. After the computer is installed, after the net card is installed, due to the start of the initial network card communication protocol, the start speed will be significantly slow, but this does not affect normal use. . -------------------------------------------------- -------------------------------------
Q: NIC POWER lights are not lit A, generally check if the network cable is inserted, whether the crystal head is firmly, whether the network card is inhaliflow, the network cable has more than 80 degrees or more, and the problem is excluded if it is not Net card change or re-laid the network card, crystal head red, or replace the NIC. -------------------------------------------------- -------------------------------------
Q: You can only find yourself every machine, see if you can't see other machine A, check if the NIC light behind the chassis flashes. If flicker, you can generally prove that the connection between the unit and the hub is normal. Otherwise, the two ends of the network cable should be checked, and the power supply of the hub is open. Ping other host IP addresses, or host names If there is no way to prove that there is a hardware problem. Otherw there is a network settings, you have to put all the machines as the same gateway below the same network segment ---------------------------- -------------------------------------------------- ------------
Q: WIN98 system does not access the resources of the XP system a, Win98 users must log in to the local system with XP existing open account passwords. And it is best in a working group. -------------------------------------------------- ------------------------------------- q: Win98 system login requires filling in Windows landing domain A Click Cancel to enter the system, then remove the Windows login domain in the properties of the Microsoft Network Client. -------------------------------------------------- -------------------------------------
Q: How to implement a two-machine or multi-machine sharing Internet network in the local area network? A: It is 2 minutes in its way, (1) Sharing the server to ensure that the local area network can connect, the server can be connected to the Internet, if the server is 56k modem dial, then install Intelnet connection sharing in Win98, ME, in NT, XP, In 2000, 2003, the shared this connection is hooked directly in the property of the dial-up connection, and then set the server network card IP address to 192.168.0.1, and DNS is not filled. The remaining workstations must only be set to set NDS to the server IP address. If the server is dialing with ADSL or using ADSL fixed IP, then you need to install a network card, then set the second block settings Its IP is 192.168.0.1, DNS is not filled. The remaining workstation DNS is set to the server IP address. This sharing is available at 98, ME, NT, 2000, XP, 2003. (2) Sharing in routing, first guaranteeing a local area network to communicate, the server can stand online, this sharing method is only available for ADSL or DDN line, if it is dial-up, set the router according to the manual provided by the router vendor, if It is virtual dialing to fill your own account, password, if it is fixed IP, fill in his IP, DNS, Gatway, and finally don't forget to restart the router. It is best to turn off the router after 1 minute after it is OK. Otherwise, many SOHO routers are sometimes settings that can be set in effect ----------------------------------- -------------------------------------------------- -
Q: WIN98 system does not access the resources of the XP system a, Win98 users must log in to the local system with XP existing open account passwords. And it is best in a working group. -------------------------------------------------- -------------------------------------
Q: The order in which the twisted pair is made. The specific production method is to exchange the first line of the RJ45 and the third line, the second line is exchanged with the sixth line, and the other unchanged. First head: orange, orange white, green, blue white, blue, green white, brown, brown white; another head: green, green white, orange, blue white, blue, orange white, brown brown white. If you use Hub to form a computer above the three computers into a local area network, twisted pairs can be taken on one by one. -------------------------------------------------- -------------------------------------
This article is very practical, but there are many mistakes, which is easy to mislead newers. These two have obvious errors / vulnerabilities, and everyone discussed, if they are wrong, welcome to correct. 1. When Win98 visits WinXP, the landlord has no problem, but the more convenient way is in
2. The production of the network cable is standard. If it is not done according to standard, it may appear unpredictable packet loss, because the line pairs are too disturbed. The landlord said that one of the corresponding answers can be used, and there are many people to do so, but they are not recommended.

[by netstar] Modify the conf / httpd.conf file in the apache directory, find addDefaultcharset ISO-8859-1 changed to #adddefaultcharset ISO-8859-1 (Enter Renewline) AddDefaultCharset GB2312 After the modification is complete, restart Apache, if not, restart the system.
There is also a way to change AddDefaultCharset ISO-8859-1 to AddDefaultCharset Off.
Q. Double-machine interconnection problem A. [By Akali] To be dual network card is because of the multi-machine, you have to connect MODEM, one card, then other people even HUB to achieve sharing, and you are just two machines, so Don't need Hub, all things you need: two machines (nonsense), three network cards (two hosts, one machine), ADSL MODEM, two network cables (one is MODEM to pick up the NIC, one It is from the host network card to another on another machine network card, pay attention to the line to be done, clearly, he knows, the line hub and the net card are different), of course, when another machine is going to be online, The host has to start, so there is also a routing method: First, your ADSL MODEM should support routing methods, then you only need: two machines, 2 network cards (one host, one another machine), a HUB, two 3 The network cable (a from MODEM to HUB, one from the host to HUB, one from another machine to HUB), this is the MODEM has been open, which machine needs to open the Internet
Q. How to set up automatic dialing A. [by chenncn] Open IE --- Tool --- Internet Options - Connection --- Select your connection name --- Select never dial-up A. [by Engewald] The ban is often not played. You can put "Disable Auto Dial Features when I log in" when I first pop up the window.

Q. The top ten secrets of private protection privacy A. [by Shanghai85] 1. Browse with anonymous ways because many websites use cookies to track users' internet activities, thus determining netizens. You can turn off the computer to receive the cookie option when using your browser to avoid tracking of cookies. 2. In response to any online transaction or send email, remember to read the privacy protection policy of reading the website, because some websites will sell your personal information to third parties. 3. Install your personal firewall to prevent personal data and financial data from being stolen. Timely upgrade is a very important ring, otherwise the role of the firewall is not fully played, and the possibility of attack is still very large. In addition, you can also use security software to keep important information, reducing the possibility of accidentally sending these materials to unsafe websites. 4. Use the security software or firewall to prevent hacker attacks and spyware (a software that connects to the external server and transmits personal data to the network). These software protect your personal computers and materials from hackers, and prevent Spyware from automatically connecting to the site and send your information. 5. When online shopping, make sure that secure connection is used. You can use the Closed Lock icon above the browser to determine if the connection is safe. 6. Hackers sometimes pretend to represent the representatives of Internet service providers and ask your password and personal information. Do not reveal these information to anyone when internet access. 7. Change your password frequently, use seven-digit passwords containing letters and numbers, thus interfere with hackers utilize software programs to search the most commonly used passwords. 8. Turn off these features when you do not need files and print shares. Although the files and print sharing features are very useful, it will also expose your computer to find a hacker for security vulnerabilities. Once a hacker enters a personal computer, it can steal private information. 9. Do not open an email attachment from a stranger. These attachments may contain a Trojan horse program that makes hackers drive the Identip computer documentation, even control peripherals, and some hackers can even submit into the Internet camera (Web Camera) to monitor. In addition, you should also install software with antiviral programs, protect computers from viruses, Trojana programs and worms. 10. You can use the real-time check of network security. For example, the security pick (www.symantec.com/securityCheck) is located in the Symantec website to determine if the computer is equipped with the ability to protect computer viruses and malicious code. This feature can also scan your computer to find security vulnerabilities and viruses, and compare the scan results with other scanned systems. So far, more than 3 million users have viewed this website, recommended. In short, today's online security is more and more important, every netizen should not hold the lucky psychology of "Black Will n't Be Me", only to do good defense work.
