How to Find An Effective Computer Work From Home

March 30th, 2010



There are many computer work-from-home opportunities over the internet today. With the many choices that you have, it is virtually impossible to pick just one and hope that it is the most lucrative one around. But really, you have to do just that. Choosing too many work-from-home opportunities will divide your attention with too many concerns. And that would cause you to have divided income as well.

The best and the most profitable business around is still the selling business. Companies earn through selling their products or promoting their service. And if you partner with flourishing company, their success is likely to brush off you. So the choice of your company is very crucial. It is only important that you select a company that has a great future and your potential for growth is secured.

The compensation that these companies give their agent is an essential factor to consider as well. You should be paid a good amount in order to build an empire. The company that has the most creative way of paying commissions is the one that you should choose. The more streams of income they have, the more chances you have from earning through their opportunity.

However, it is essential that the company really have the ability to pay you back. Some companies are very bold in showing their agents the different ways to earn. But come pay check time, they are struggling to send you your money. Check the background of the company that you would like to join. The longer they are in the business, the better. And the more satisfied their roster of agents with the payment schemes, the better it is for you.

There are many MLM opportunities in the internet today. But not all of them can genuinely make you rich. You have to specifically choose the program where you know you can perform well. You can choose according to your likes, preferences, experiences, and expertise. The more you know about the opportunity, the better you will perform on it. If you like the products, you will sell it easier. If you know about the process and the product, you will be able to show your customers the advantages of using them instead of trying anything else.

The real key in generating massive income from the internet or through your computer is investing your time, effort, and knowledge on it. Without actual hands-on experience on the job, you won’t be able to get the income stream that you really want. Be sure that you learn everything about the company and the rest of the processes around it. This would allow you to formulate the right strategies that make allow you to earn the best possible way.

Support is also important. Be sure that the company you will be joining has lots of tools, resources, and community that you can take advantage of. These tools could help you a lot without requiring you to make additional investments.

If you are new in this type of business opportunities, especially in MLM’s, try to join something that virtually has no start-up costs. This would allow you to just have the feel of the entire business without losing anything. After you know the ropes, then you should be ready for bigger risks and for bigger income.

The Internet – The Largest Network in the World

March 3rd, 2010



Computer engineers have been finding ways to connect computers and their devices together in different ways. Computer networking has come hand in hand with other bodies of knowledge such as telecommunications, information technology, and computer engineering. So many things have been made possible through computer networking. It has helped people live easier lives in many ways through personal area network, local area network, metropolitan area network, and wide area network.

One great example of a wide area network is the champion of all networks, the Internet. It is the biggest network in the world, and billions of data (maybe even trillions) is being transferred everyday. So much information is exchanged and it has practically changed the way we live our lives.

Education online

The usual way to get your education is to enroll in a school, and go to your classes on a fixed schedule. Nowadays, we can actually get a college and master’s degree through the Internet. A lot of reputable universities now offer their courses online because they understand how hard it is for some students to juggle a job and their schooling. Depending on the program, you can have your own schedule, and usually you’d just have to submit work on or before a particular deadline. At times, you’d have real time chatting with you professor and “classmates”, sometimes even with a webcam. What’s great about this is that you no longer have to go through the hassle of commuting. The good news is that companies have been accepting a lot of applicants with this sort of education but there are still some that are overly traditional.

Video games galore

What started out as simple 2 dimension games is now a multi-billion dollar industry, and has spawned a new way of social interaction. Because of the Internet, gamers are now able to interact with people from across the globe, and play the same game at the same time. This is great because video games were once viewed as an anti-social activity. This is no longer true and now gamers not only get to play the game together, but are able to chat and make new friends as well. Internet gaming has also created a new gaming genre called “massively multiplayer online role-playing games” or MMORPGs. This is a supercharged type of RPG where thousands of players get to play together in a particular game at the same time.

Social Networking

A lot of websites nowadays allow people to interact and socialize with each other with their different tools and services. Some of them are focused on dating, where users can create their own profile and indicate their particular tastes. Other websites are dedicated to people uploading pictures and sharing them with other users as well. This has been a great way of connecting with long lost friends, and making new ones as well.

It’s great that computer networking has helped in bringing us the Internet. With it, life has become more convenient, and we can learn so many new things everyday just by connecting to it. With the Internet, there are certainly more new things to come.

Finding Your MAC Address On Wired And Wireless Network Cards

December 2nd, 2009



The Answer To The Media Access Control Question

Over the past few weeks I have received quite a few e-mails about Ethernet cards, both wired and wireless, and more specifically, about Media Access Control (MAC) addresses. I think the main reason I’ve received so many questions about Ethernet cards and MAC addresses is people trying to secure their home wireless networks and their desire to use MAC address filtering. This type of filtering in wireless networks can be configured to allow or deny specific computers to use or attach to the wireless network, based on the MAC address.

My first thought was to write an article just about MAC addresses and wireless Ethernet. After thinking about it I decided to expand on this and go over some specific information about Ethernet cards and communication.

Different Ways Of Finding Your MAC Address And More

There are several ways of finding your Ethernet and communications protocol information. Many Ethernet card manufacturer’s have proprietary software that can reveal this information but they work differently depending on the manufacturer. So we will use the Windows 2000 and XP “ipconfig” utility since this is available in the majority of Windows Operating Systems.

First, go to “start” -> “run” and type “cmd” without the quotes. Then hit the enter key. At the command line type “ipconfig /all”, again without the quotes. Actually, just typing ipconfig without the /all will work but will only provide you with abbreviated information regarding your network cards. An example of what you might see by typing the “ipconfig /all” command is below with each item commented in green lettering:

Fault Tolerant And Highly Availability Computer Systems

There are several ways of finding your Ethernet and communications protocol information. Many Ethernet card manufacturer’s have proprietary software that can reveal this information but they work differently depending on the manufacturer. So we will use the Windows 2000 and XP “ipconfig” utility since this is available in the majority of Windows Operating Systems.

First, go to “start” -> “run” and type “cmd” without the quotes. Then hit the enter key. At the command line type “ipconfig /all”, again without the quotes. Actually, just typing ipconfig without the /all will work but will only provide you with abbreviated information regarding your network cards. An example of what you might see by typing the “ipconfig /all” command is below:

OutPut Of The “Ipconfig /All” Command

Windows IP Configuration

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

This is the name of your computer, typically defined during the windows installation. However, it can be changed after installation.

Primary Dns Suffix . . . . . . . : domain.com

If your computer participates in a network such as a Microsoft Windows domain this item may contain the name of the domain.

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

The Node Type may say Unknown, or peer-to-peer, or in some cases “hybrid”. It is a setting that has to do with the Windows Internet Naming Services used in certain types of Windows domain networks.

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

This setting determines if Windows XP or 2000 will function as an IP router. If you have two or more network cards you can setup your system to act as a router, forwarding communications requests from one network to another. Windows 2000 can be configured to do this in a pretty straight forward fashion; Windows XP will need a registry modification.

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

WINS Proxy is another setting that is related to the “Node Type” we discussed earlier. It is normally not a required setting in a home or small office network, or newer types of Microsoft Windows domains.

Ethernet adapter Wireless Network Connection 2:

If you have multiple Ethernet (network) cards in your systems, as I do in this laptop, you will have multiple listings. This one happens to be the second Ethernet card, an internal wireless Ethernet card.

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 totally 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 hence 6*8=48(bits). The first 3 codes identify the manufacturer of the card and the remaining codes are used to create a unique number. Theoretically there should never be a card with same MAC address on a local network. However, there are a few exceptions. There are software tools that allow you to change this code. In fact, this is a step some hackers take to attack other systems on a local network. I say local network because MAC addresses are not routable between network segments. By spoofing this address, you can impersonate another machine on the local network. Traffic that was bound for the intended target can be redirected to the hacker’s machine. This is the address you would also use to populate a MAC address, or physical address table when setting up your wireless access point to support MAC address filtering.

DHCP Enabled. . . . . . . . . . . : Yes

DHCP, or the Dynamic Host Control Protocol, if enabled means your computers IP address is being provided by a DHCP server on you network. The DHCP server could be your wireless access point, cable/dsl router, cable modem, or a server on your network. Also, if a DHCP server is not enabled on your network, your computers Operating System will auto generate a random IP address within a certain predefined range. This means you could network a group of systems together without having to manually assign the IP settings.

IP Address. . . . . . . . . . . . : 192.168.0.117

This parameter provides you with your current IP address. The address listed above is what is called a “private” address. There are certain classes of IP addresses that have been set aside for private use. This means for your internal, local, or private network at home or office. These addresses are not, or should not, be routable on the Internet. The Internet routes what are called “valid” IP addresses. Your cable/dsl router or cable modem has a valid IP address assigned to its “external” network interface. The external interface may be your phone line or cable TV cable.

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

The Subnet Mask is a special number, or in some sense, filter, that breaks down your IP address, in this case private IP address, into certain groups. IP addresses and Subnet Masks can be a complicated matter and would take an entire article to go over.

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

The default gateway, the IP addresses listed above, is the IP address of the device that will route your request, such as when you try to browse a website, to the Internet. It is a bit more complicated than that though as gateways or routers can route traffic to various different networks, even other private networks. At your home or small office, this gateway most likely is your cable/dsl modem or router.

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

The DHCP server, remember we talked a little about this above, is the device that assigns your computer an IP address and other information. DHCP servers can assign all kinds of information such as; Default Gateway, Domain Name Servers (DNS), IP address, Subnet Mask, Time Server, and much more.

DNS Servers . . . . . . . . . . . : 192.168.0.49, 64.105.197.58

DNS Servers are internal or external servers that resolve Fully Qualified Domain Names (FQDN), such as http://www.defendingthenet.com , to IP addresses. This is done because computers don’t actually transmit your requests using the domain name, they use the IP address assigned to the FQDN. For most home or small office users, the primary DNS server is the IP address of your cable/dsl router. Your cable/dsl router than queries an external DNS server on the Internet to perform the actual resolution of the FQDN to IP address. The address 192.168.0.49 is an internal private device on my network whereas the 64.105.197.58 is an external public Internet DNS server and is present just in case my router has trouble performing the DNS resolution tasks.

Lease Obtained. . . . . . . . . . : Sunday, March 19, 2006 6:38:16 PM

This information tells you when your computer received its IP address and other information from a DHCP server. You will notice it says “Lease Obtained”, that is because most DHCP servers only lease the IP address to you from a pool of available address. For instance, your pool may be 192.168.1.1 through 192.168.1.50. So your DHCP server has 50 IP addresses to choose from when assigning your computer its IP address.

Lease Expires . . . . . . . . . . : Wednesday, March 29, 2006 9:38:16 PM

When the IP address, assigned by the DHCP server, lease expires it will attempt to lease you the same or another IP address. This function can typically be changed on the DHCP server. For instance, on some fully functional DHCP servers, you can configure the Lease to never expire, or to expire within 1 day and so on.

Why Are MAC Addresses So Important And How Do They Work

To jump back to MAC address for just a bit. You may 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 speak with another computer on a local network, it will make a broadcast request, or ask a question, of who owns a particular IP address. For instance, your computer may say “Who is 192.168.0.254”. Using the information above, my default gateway is 192.168.0.254 and will answer “I am “00-90-4B-F1-6E-4A” 192.168.0.254”. It sends back its MAC address. That MAC address then goes into what is called a Address Resolution Protocol (ARP) table on your computer. You can see this information by going to the command prompt like you did above and typing “arp –a”. You will get information like the following:

Internet Address Physical Address Type

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 A Hacker Can Use MAC Addresses In An Attack

You will notice the IP addresses and to the right of them the MAC addresses. Without this information, without the MAC address, you would not be reading this article right now. MAC addresses are not routable like IP addresses. They work on your local or private network. However, devices on the Internet perform the same tasks. Routers and switches maintain a list of their peer devices MAC address just like your computers and devices on your home or office network. I mentioned above that MAC addresses can be changed in order to redirect requests. For instance, if I were on your office network and you had an internal web server that took personal information as input, I could tell your computer to go to my laptop for the web site by broadcasting my MAC address tied to the real web servers IP address. I would do this when you computer asked “Who is the “Real Web Server””. I could setup a fake web server that looks just like the real thing, and start collecting information the real web server would normally collect. You can see how dangerous this can be.

Conclusion

There are several other easy ways you can find your MAC address but they can be a little confusing if you have more than one internal network card. Most external USB, or PCMCIA wired and wireless Ethernet cards have their MAC address printed on them. In cases where the wired or wireless network card are inside 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.
