¡¡¡NETWORK COURSE!!!

In this section we will consider only nets mounted on the Microsoft family of TCP / IP. So far we have moved in the transport and network layers. However, Windows goes further and uses a new protocol at the application layer, called the NetBIOS protocols to encapsulate the lower layers. Microsoft networks are characterized by the use of NetBIOS. Windows 98 computers can function as both clients (accessing shared resources) and server (providing resources). Therefore, the networks will be in Windows 98 peer networks: there is no hierarchy of computers, anyone can play the roles of client and server. In the "Windows NT Network" will study the client / server architecture. 4.1 NetBIOS Protocol It is a name resolution protocol that can be encapsulated over TCP / IP. NetBIOS operates at the application layer, giving a uniform appearance on all Windows networks regardless of the protocols used for the transport and network layers. Lets share files and printers as well as see the resources available in Network Neighborhood. NetBIOS uses ports 137, 138 and 139. Protocol is a unique Windows machines. We can see if our computer NetBIOS is enabled using the command netstat-an. This command will inform us if we have the three ports earlier in LISTENING mode. C: \ WINDOWS> netstat-anConexiones active remote Proto Local Address Foreign Address State TCP 192.168.0.2:137 0.0.0.0:0 LISTENING TCP 192.168.0.2:138 0.0.0.0:0 LISTENING TCP 192.168.0.2:139 0.0.0.0:0 192.168.0.2:137 LISTENING UDP *: * UDP 192.168.0.2:138 *: * Much of the criticism of Windows security settings to focus on the NetBIOS protocol. For security reasons, you must disable this protocol provided that it is not essential. Let's see examples 4, who needs to have active protocol NetBIOS (ports 137, 138 and 139 open)? Who should disable? A web server A Windows 98 connected to the Internet via a modem A Windows 98 that participates in a corporate network Server users and files In the first case, NetBIOS should be disabled as a web server does not share resources through Network Neighborhood or accessing shared resources from other computers (the web service, HTTP, it works only with TCP / IP). In the second case, NetBIOS is not needed for the same reasons. In case number three things change because this computer will probably need access to shared resources of other computers and print to remote printers. The server also requires four example NetBIOS. Is necessary so that other users can access their files in a comfortable way. Note: You can access files from other computers without NetBIOS enabled? Yes, of course: using the services of TCP / IP. Specifically, the service or FTP file transfer. The computer provides the resources are configured as an FTP server (port 21 open). The other computers will use an FTP client to connect to the server. However, this does not work directly on remote files, it is necessary to make a previous copy of the files to your computer before making changes. How to disable NetBIOS in Windows 98 We have probably noticed that the box "Enable NetBIOS over TCP / IP" in the NetBIOS tab of the properties of TCP / IP is checked and no change. The command netstat-an tells us that we open NetBIOS ports. How can we disable NetBIOS? The key is in the Client for Microsoft Networks. This component provides access to network shared resources of other computers (which is the open ports 137, 138 and 139). It is also required, in addition to the service File and Printer Sharing for Microsoft Networks to share resources in the network. Customer. Allows access to resources from other posts in the network. Using the Client for Microsoft Networks. This component is responsible for the logon screen that displays when you boot Windows for a user name and password. In the properties of this component indicates whether we are assembling a network of equals (box "Log on to Windows NT domain" is disabled) or a network client / server (box enabled). Adapter. Each card is real or virtual network that we have installed on your computer. The network cards are those actual physical slot in a free computer. The virtual cards are those that emulate Windows to install a network card, but do not really exist. The most common is the Adapter Dial-Up Networking that corresponds with modems or ISDN adapters computer. Protocol. It is the language we use our computers to communicate with the other posts in the network. While you can define several protocols for the same adapter, it is advisable to avoid unnecessary traffic on the network. Use the TCP / IP. In small networks (fewer than 10 PCs) and locked to the Internet can be considered using the NetBEUI protocol instead of TCP / IP. Service. Corresponds to the server side of our computer. Use the File and Printer Sharing for Microsoft Networks. Using the "File and Printer Sharing" is offered if you can set files, printers or other resources to both computers on the network. This service requires that you installed the Client for Microsoft Networks. The installation of a TCP / IP in Windows 98 is to follow the following steps for each position of the network: Install the network adapter. Like any other device installation is divided into: a) installation. Place the network card in a slot free. If we had problems with how the card after you've done all the settings, try to exchange the slots of the network card with another previously installed (this forces a different allocation of IRQs). B) Installation logic. It is recommended to install the latest drivers from the manufacturer. In the case of Realtek network cards (identified by observing the main integrated circuit card) drivers are available in www.realtek.com.tw. Install TCP / IP and configure it. (See Course TCP / IP). Install Client for Microsoft Networks. In the properties of the component box "Log on to Windows NT domain" should be unchecked. The "Log-main" should indicate "Client for Microsoft Networks." Configure NetBIOS identification. In the "Identification" tab we have to give a name for the PC (different for each of the network) and a name to the working group (probably the same for the whole network). The working groups are a way to organize the computers in Network Neighborhood, do not impose restrictions on access. Install File and Printer Sharing Service for Microsoft Networks and set it up. Just what will we do if we want the PC acting as a server. After the computer restarts, Windows (more specifically the Client for Microsoft Networks) will request a username and password. At this moment we must choose a username and password you'll use the rest of times they logged on. If we do not go and pressing "Cancel" will not be able to access network resources (Network Neighborhood will not work). Note: We can have multiple network adapters and protocols for each individual. Each protocol is linked with a network adapter. For example, we may have the NetBEUI protocol bound to a network card "Realtek RTL8029" and TCP / IP bound to the adapter Dial-Up Networking. " Links that are not essential should cancel to avoid unnecessary traffic on the network. Network password and Microsoft Windows password Windows uses two types of passwords to log on: Microsoft network password. Is required to access network resources. Validates us as network clients. According've set the box "Log on to Windows NT domain" of the properties for "Client for Microsoft Networks" are the following cases: Box unchecked. Equivalent to a peer network. We can enter any username / password. As there is no computer that validates the password that we all happen to be valid. No security: any user can access networked resources. Box ticked. Equivalent to a network client / server. The username / password you write will be verified by the primary domain in which we are logging. Only properly authenticated users can access networked resources. Note: In the two previous cases we can "jump" the network password window by pressing the "Escape" or "Cancel" button. In this way we will have access to the computer but not the local network resources. Windows password. Refers to local computer, not the network. However, it imposes restrictions on access to users, is the only key to store passwords for other Windows, as the key to "Dial-Up Networking." Passwords are managed from the Windows Control Panel / Passwords. Only you will be asked the user if the network password that Microsoft had previously entered does not match a valid Windows password. Typically, therefore, is that both passwords match, so that the user has to type only once. Users who have logged on to a computer with a password must enter the same the following times. Otherwise, the system does not allow the switch. However, it can give users a new high just typing. Note: We can "jump" the Windows password window by pressing the "Escape" or "Cancel" button. However, we do not see any passwords stored in Windows dialog boxes (you will have to type again). In addition, some programs will not be able to store our personal preferences. Note: Windows passwords are stored in *. pwl files for each user. We can remove all the lists of Windows passwords simply by removing the *. pwl files stored in the Windows directory. How to proceed? Usually only the writing password for Microsoft Network so that it matches the password for Windows. The first time we are asked to confirm the Windows password (the system will be creating a new user), but these often only have to type the password once (Windows will warn that both passwords match). According to the above explanations, we must always authenticated users and not go with the "Cancel" button. This process can be automated using the Tweak UI tool

¡¡¡DATABASE!!!

A database or database (in Spanish: Database) is a set of data within a systematic and stored for later use. In this sense, a library can be considered a database comprised mainly of documents and printed texts on paper and indexed for reference. At present, due to technological development in fields such as computing and electronics, most of the databases are in digital format (e), which offers a wide range of solutions to the problem of data storage.
