Understand your home network

A home network is a very complex issue. Taking information from one place to another, which might not eve on the same continent is a pretty big deal. This article will not go into too much technical jargon, but it will be an in-depth answer to the general (and some complex) questions about networking, especially wireless networks. We see the most fundamental aspects of a wireless network in a question / answer format.

How does the signal get my computer to myrouter, Internet, and vice versa?

When a computer user is connected to the Internet are almost constantly sending signals to multiple locations. The way this is done from binary code. Any user is not divided and transmitted in binary code (in this case, wireless) to the router and then to the destination that you gave. In the case of a wireless connection, the card is sent to the wireless router using a protocol called CSMA / CA (CarrierSense Multiple Access with Collision Avoidance) that allows only one node (or computer) access to the router at once. If a computer uses the router and a second computer may also use the second system is sent a "busy signal" and must wait a certain period of time. When time expires, the request of the computer. For reference, a cable connection using CSMA / CD (Carrier Sense Multiple Access with Collision Detection), which allows the computer to sense whenanother node is using the router. In this way the request is sent in the first place.

This, of course, makes more sense, but it is not possible with a wireless connection, since there is no permanent connection to the router. Connections involving stops when the request is met, unlike the cable connection that is always the cable. The router is now based on the OSI 7-layer model (which is too large and sophisticated to fit in this article, but Google can andfriend) host.Basically to receive information to and from the destination, the router (which by the argument will run as a DNS server in this scenario) is the IP address assigned by Google and launches its request Google for their web server . The link is at the door 80 for accessing a Web page and then processed by a web server for Google. The signal is sent in the same way it was sent from the computer. When it comes toback, the user sees on the display of Google. This process is done very quickly if you see sometimes a matter of less than one second. If you live in the U.S. and the Web server in China (again, just for the sake of argument), the speed with which this happens is quite impressive to the uninitiated. This is a brief description of how the process works.

What protection is available for wireless networks?

There are some optionswireless encryption. Encryption is very useful because it helps to get people out of your wireless network, if they should not. This is basically a password protection for the connection. Some of the most popular choices are:

WEP (Wired Equivalent Privacy)

WEP uses a 128-bit encryption system using a series of 26 hexadecimal (base 16) characters. 256-bit is available, but historically it is quite unusual. This encryption method is a bit 'datedbut it is still used by some. This is replaced by safer WAP and WAP2 discussed below. The way in which a computer is checked by receiving a clear challenge to the router for encryption and the challenge of delivery.

WPA and WPA2 (Wi-Fi Protected Access)

WPA2 is preferred by many because it is probably the safest available for home users. A 256-bit key used to encrypt all network traffic. There are two types of WPA, TKIP and PSK. Let usdiscuss this a bit ':

TKIP

Temporal Key Integrity Protocol (TKIP) was designed originally designed to replace WEP WEP without replacing the hardware. The repaired many of the flaws of WEP, but has had its problems, including the ability to be decoded by others in short bursts. This was a problem with the WEP, which is passed, TKIP.

PSK

Pre-Shared Key mode (PSK) is designed for those who do not need sophisticated security, such as home users. A number of minorCompanies use this as well. It offers a password-protected security is in decent though not as strong as a large company can have. Many home users to implement this because of its ease of use. The only real weakness of this protocol that a user at home should be concerned about a weak password. weak passwords are the main reasons that sometimes lose some effectiveness.

Advice on network security

There are some things that the average home user can do to ensuretheir network and your computer from intruders. The network, set a strong password is essential. This should be placed at the top of someone. Second, by hiding the router Service Set Identifier (SSID) works very well. If the hacker can not find the network, can not penetrate the network. What if one of the personal computer, immediately change the Administrator account a different name. Hackers try this account most of the time, in order to gain administrative access onuser. If the user name is still responsible for the potential attacker has won half the battle. The only unknown is the password. However, if the FozzyBear administrator user name or user name or password is known and the attacker has to spend much more time and will probably just give up, even if they manage the network. As a side note, a good anti-virus and firewall are not forgotten. These are vital for information security generally.

DNS names like Lost

DNS translates the name of the site in an Internet address. When a user requests a URL you type into your browser and return to the website on the screen, in fact, a DNS server receives a request from a URL and translate it into an IP address, which is the address of the site. Because it is much easier for the human mind to remember a name rather than a long track that is why the use of DNS to translate the site name to an IP address from an Internet actuallyunderstand and be able to deal with.

DNS can answer three types of queries that a user can do to a DNS server recursive, iterative, and inverse. The principal of a DNS server can server a resolution system (which would normally call a customer / user) or a different DNS.

DNS names like Lost?

1. The DNS resolver sends a recursive query to the local DNS server asking for IP address of the requested site.The local name server is responsible for name resolution and can not refer the resolver to another name server.

2. The local name server to check the areas and found no areas corresponding to the requested domain name.

3. The root name server is authoritative for the root domain and responds with the IP address of a name server. Com TLD.

4. The local name server sends an iterative query for the name of the siteL '. com name server.

5. L '. Com name server responds with the Internet address of the nameserver maintenance of the domain name requested.

6. Then the local name server sends an iterative query to the site on name server.

7. name server of the site meets the Internet is the name of the site.

8. The local name server sends the IP address of the site's name back to the original requestedresolver.

The speed of the computer by changing the DNS settings

The DNS server at your Internet Service Provider does not give you what you need to use to connect to the Internet. DNS stands for Domain Name Server. In reality it is a machine on the Internet that translates the website that you type into your browser address IP of the server where the Web is actually located. DNS server can be problematic and should be continuously monitored and maintained. If the DNS you are using is bad orproblem, you may have problems with certain websites, while the load of other purposes. Another problem may be that the DNS is hard, so your internet connection slower than usual. So if you try to access certain Web pages in case of problems with pages not loading, change the DNS settings and see if that solves the problem.

Change DNS settings on the router

Changing the DNS settings may be useful to you, soIt will apply to any computer on the network. Each page of the router's configuration is different, so you may need to lock your router documentation to find the DNS settings and change these settings. First you need to access the router through your web browser. If you do not know how to do this, just do a Google search on "login to the router via a Web browser." It 'important that you write down your current DNS numbers, so if you have problems, you can returnthe old settings.

Follow these steps:

1. Log in to your router
2. Find your DNS settings
3. These settings for the following

Public DNS server

Google DNS

8.8.8.8

8.8.4.4

OpenDNS

208.67.222.222

208.67.220.220

DNS Advantage

156.154.70.1

156.154.71.1

Every one of those DNS servers. OpenDNS is a service that gives you morefeatures such as sites for monitoring and control. These are all free, so do not worry about getting the cost for its use. Try to experiment and see what works for your computer.

Finding the MAC address on wired and wireless network cards

The response of the Media Access Control Question

In recent weeks I have a lot 'of e-mails about Ethernet cards, both wired and wireless, and more specifically, about Media Access Control (MAC). I think the main reason that I have received many questions about Ethernet cards, and MAC addresses is people trying to own wireless home networks and their desire to use the MAC address filtering to secure. This type of filter in wireless networks can be configured toAllow or deny use of specific computers or connect to the wireless network based on the MAC.

My first thought was that of a single article on wireless Ethernet MAC addresses and write. After thinking, I decided to expand on this and to move some specific information about Ethernet cards and communication.

Different ways to find your MAC address and much more

There are several ways to Ethernet protocol and communication and information. Many Ethernet cardmanufacturer's proprietary software that can reveal this information, but behave differently depending on the manufacturer. So we'll use the Windows 2000 and XP "ipconfig" utility since this is available in most Windows operating systems.

First, go to "Start" -> "Run" and type "cmd" without quotes. Then press the Enter key. At the command prompt type "ipconfig / all", again without the quotes. In fact, just typing ipconfig without the '/ all will work, but it will onlyprovide summary information of network adapters. An example of what one might see by typing "ipconfig / all" command is below each said in green:

Fault Tolerant and High Availability Computer Systems

There are several ways to Ethernet protocol and communication and information. Many software vendors Ethernet card owners who can reveal this information, but behave differently depending on themanufacturer. So we'll use the Windows 2000 and XP "ipconfig" utility since this is available in most Windows operating systems.

First, go to "Start" -> "Run" and type "cmd" without quotes. Then press the Enter key. At the command prompt type "ipconfig / all", again without the quotes. In fact, just typing ipconfig without the '/ all will work, but provide only summary information of network adapters. An example of what one might see by typing"Ipconfig / all" command is as follows:

Output of "ipconfig / all" command

Windows IP Configuration

Host Name. . . . . . . . . . . . : Home Computer

This is the name of the computer, usually defined during the installation of Windows. However, it can be changed after installation.

Primary DNS Suffix.. . . . . . : Domain.com

If your computer has an active network, such as a Microsoft Windows domain this entry may contain the name ofdomain.

Node Type. . . . . . . . . . . . : Unknown

The node type can say unknown, or peer-to-peer, or in some cases "hybrid". It is an institution that has to do with Windows Internet Naming Services used in certain types of Windows domain networks.

IP Routing Enabled. . . . . . . . : No

This setting determines whether Windows XP or 2000 functions as an IP router. If you have two or more network cards you can configure the system to act as a router, forwarding communicationsrequests from one network to another. Windows 2000 can be configured to do this in a nice straight forward, Windows XP will need a change in the registry.

WINS Proxy Enabled. . . . . . . . : No

WINS Proxy is another institution that is linked to the "Node Type" we discussed earlier. It is not normally a required setting in a home or small office or the newer type of Microsoft Windows domains.

Ethernet adapter Wireless Network Connection 2:

If youover Ethernet (network) cards in your system, if I were in this laptop, you will have multiple listings. This is the second Ethernet card, a wireless Ethernet card inside.

Description. . . . . . . . . . . : Broadcom 802.11b / g WLAN

This is the description of the Ethernet card, usually the name / manufacturer and type of Ethernet card. In this case it is a Broadcom wireless Ethernet card built into my laptop.

Physical Address. . . . . . . . . :00-90-4B-F1-6E-4A

And here we have the MAC address. The MAC address is a 48-bit hexadecimal code and is suppose to be a completely unique address. It is 48 bits because each number or letter in hexadecimal represents 8 bits. Hexadecimal numbers range from 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F. There are 6 alpha-numeric codes is 6 * 8 = 48 (bit). The first 3 codes identify the manufacturer of the card and the other codes are used to create a unique number. Theoretically there should never be acard with the same MAC address of a local network. However, there are some exceptions. There are software tools that allow you to change this code. In reality, this is a step some hackers take to attack other machines on a local network. I speak the local network because MAC addresses are not routable between network segments. By spoofing this address, you can impersonate another machine on the network. Traffic that was bound for the objective may be redirected to the hacker's computer. This isthe address is also possible to use a physical address or MAC address table before setting up wireless access point to support MAC address filtering to people.

DHCP enabled. . . . . . . . . . . : Yes

DHCP or Dynamic Host Control Protocol, if enabled means your computers IP address provided by a DHCP server on the network. The DHCP server can cable wireless access point / router DSL, cable modem or a network server. Although aDHCP server is enabled on the network, the computer operating system will automatically generate a random IP address within a predefined interval. This means you could network a group of interconnected, without having to manually assign the IP settings.

IP address. . . . . . . . . . . . : 192.168.0.117

This parameter allows your current IP address. The address above is what is called a "private" addresses. There are several classes of IP addressesare reserved for private use. This means that for the internal network, local or private home or office. Such addresses are not, or not, are routable on the Internet. The Internet routes called "valid" IP addresses. The cable / DSL router or cable modem has a valid IP address assigned to the "outside" of the network. The external interface of the phone or cable TV cable.

Subnet Mask. . . . . . . . . . . : 255.255.255.0

Subnet Mask is aspecial issue, or in a sense, the filter, which breaks your IP address, in this case a private IP address in certain areas. IP addresses and subnet mask can be a complicated issue and would require an entire article to be about.

Default Gateway. . . . . . . . . : 192.168.0.254

The default gateway IP addresses of the above, the IP address of the device that will route your request, such as when you try to browse a website on the Internet. It 's a bit complicatedthan that, but as a gateway or router traffic to different networks, the other private networks. At home or small office, this gateway most likely is your cable modem / DSL or router.

DHCP Server ... . . . . . . . . : 192.168.0.49

The DHCP server, remember we talked a bit 'above, the device indicates that the computer has an IP address and other information. DHCP server can assign all kinds of information, including: StandardGateway, DNS (Domain Name), IP address, Subnet Mask, Time Server, and more.

DNS Server ... . . . . . . . . : 192.168.0.49, 64.105.197.58

The DNS servers are internal or external, to fully resolve the names (FQDN), such as http://www.defendingthenet.com full domain of IP addresses. This is because computers are not really about your request using the domain, use the IP address assigned to the FQDN. For mosthome or small office, DNS server IP address from your primary Cable / DSL Router. The Cable / DSL Router to ask an external DNS server on the Internet to perform address the effective resolution of the FQDN to IP. The address 192.168.0.49 is an internal private device on my network that 64.105.197.58 is an external public Internet DNS server and is available in case my router has difficulty performing the DNSResolution tasks.

Lease obtained. . . . . . . . . . : Sunday, March 19, 2006 18:38:16

This information tells you when the computer received its IP address and other information from a DHCP server. You will notice that says "Lease obtained", it is because most of the DHCP server just give the IP address lease from a pool of addresses available. For example, the pool may be 192.168.1.1 through 192.168.1.50. So your DHCP server has 50 IP addresses to choose from whenassigning the IP address of your computer.

Lease expires. . . . . . . . . . : Wednesday, March 29, 2006 21:38:16

If the IP address assigned by the DHCP server will attempt to lease expiring lease is the same or a different IP address. This can usually be changed on the DHCP server. For example, on some fully functional DHCP server, you can never rent due within one day and so on.

Why are so MAC addressesImportant and how they work

To jump back into the MAC address for just a bit '. You might think that IP addresses are the most important thing when it comes to network communication. The reality is, MAC addresses are very important because without them computers would not be able to communicate over Ethernet networks. When a computer wants to talk to another computer on a local network, broadcasts a query, or ask a question, who owns a particular IP address. For example,The computer can say, "Who is 192.168.0.254". Using the information above, my default gateway is 192.168.0.254 and say "I am" 00-90-4B-F1-6E-4A "192.168.0.254". You send the MAC address. That the MAC address then in what is called a (ARP) Address Resolution Protocol table on your computer. You can use this information to the command prompt like you did above and typing "arp-a". You can obtain information such as the following:

Internet Address Physical AddressType

192.168.0.49 00-12-17-5C-A2-27 dynamic

192.168.0.109 00-12-17-5C-A2-27 dynamic

192.168.0.112 00-0C-76-93-94-b2 dynamic

192.168.0.254 00-0E-2E-2e-15-61 dynamic

How can a hacker use MAC addresses in an attack

You will notice that the IP addresses and the right of their MAC addresses. Without this information, without the MAC address, it would not be reading this right now. MAC addresses are not routable, such as IP addresses. They work on localor private network. However, the devices on the Internet, to perform the same tasks. Routers and switches keep a list of their colleagues MAC address devices such as computers and devices on your home or office network. I mentioned that MAC addresses can be modified to meet demand. For example, if I'm on your corporate network and you had an internal Web server that took personal information as input, I could tell the computer to my laptop for the websitebroadcasting my MAC address with the real web server IP address. I would do if the computer asks, "Who is the" Real Web Server ". I could set up a fake web server that looks just like the real thing, and start gathering information that the real web servers normally collect. You can see how it can be dangerous.

Conclusion

There are many other simple ways to protect your MAC address, but can be a bit 'of confusion if you have more than oneinternal network. Most external USB or PCMCIA wired and wireless Ethernet cards have their MAC address printed on them. Where the wired or wireless network adapter in your computer, such as in laptops, the MAC address is sometimes printed on the bottom of the laptop. Even Desktop systems cards that are inserted in PCI slots have the MAC address printed on the Ethernet card.

Slow Why is YouTube? Information on how to fix If your YouTube is running slow

Many frustrated users addicted to video streaming this question. Although the abrupt deceleration of the giant video site occurs sometimes at the user side, people are clueless as to the cause of this problem. It is understood no body wants to wait long for the video to load and then watch them especially when the videos are longer and in different areas. Faster streaming is the need for any Internet user. If YouTube is slow at times there are certainly a number of reasons behindthat. Most people are not sure what to do in this situation and make the videos load faster on YouTube.

Before sharing the guidelines to address the reduction of speed, I would like to invite you to think about the reasons for the failures of YouTube, as the slow streaming, flash crashing into YouTube videos to YouTube and other errors. There are two main reasons for these annoyances. One is the problem with the speed of the end user's computer, the speed of the Internet, Windows PC errors, computer containsprograms like Flash matters of conflict, while the second reason may be caused by the server or external internet traffic load. Although the site is very effective in keeping you see some problems sometimes. This is not a serious problem because we all have confidence in the services of such a website user-friendly. The problem becomes serious when the errors and low bit rate video is routine. This should be something to do with the personal computer.

Here I amwhere a couple of tips that will help to speed up YouTube for you:

* Check to repair the Windows registry and fixing Windows errors are the cause of many browsers and application errors cause a conflict.
* Test your computer for viruses and spyware.
* Run speed test to see if you have enough bandwidth to play YouTube videos easily without the site to run slowly.
* Make your Internet and reconnectknow why YouTube is slow and if it is because of poor internet on your side.
* I Turn to some of the browser plug-in that allows you to reduce the services to run in the background while you play online video.
* Try to change your version of Flash Player. While YouTube has begun streaming video through a new technology, there is still a large number of web sites using the Flash platform. So it's a good idea to try to change the version of Flash Player to playvideo without crashing and error messages.
* Test your browser. A good browser to play videos from YouTube, Google Chrome. If you have not tried to go for it. Also check with your ISP if you restrict your bandwidth to the specific terms of the day.
* The study recommends the following procedure if your YouTube is slow due to DNS-related settings:

Click Start> Settings> Control Panel> Network Connections> LAN / Your standard InternetConnection> Properties> Internet Protocol TCP / IP> Properties, uncheck "Use the following DNS server addresses" and use this address: Preferred DNS server: 208.67.222.222 Alternate DNS server: 208.67.222.220
