Modern wireless networking products are inexpensive, easy to install and very convenient. They are also full of holes ... security holes, that is.
The reason for this, can be traced to the popularity of wireless. The wireless network is firmly anchored in the computer market at home, and that means that people who buy the products can not be assumed to have any type of computer expertise; therefore, the products had better be extremely easy to configure and use.
The ease of use and security tend to be out of the other. So for wireless manufacturers, the reasoning is that, while the average Joe or Jane Smith house is nothing they really want to hide from the world, or the world would really care to learn about them, they will be very angry when obtaining they can practice their new wireless router quickly and without help does not work.
Unfortunately, the only way to make such a router without wireless idiot proof a default device settings complex that the user needs to use a parameter to one of the other wireless hardware change. By extension, this means that each wireless device can connect with said router with the default settings.
Again, this means that all wireless devices within range can connect to the new Smith router. Now, if you're Joe Smith, do you have something you want to hide?
There are a few reasons why wireless networks are less secure than their wired counterparts. First, there is the fact of their physical nature. They are wireless, transmission of a signal over an area. Each computer in this field with the right equipment can be considered "connected" to the network.
No similar access easier son to the network for everyone. This also makes it one of the most popular hacking tactics lot easier: packet sniffing or capturing network traffic for analysis for more information. Anyone coming within range can receive all traffic on the wireless network.
Second, the current methods of security technology without most available wireless, 802.11b, or easy to beat or difficult to implement.
The two most common methods for secure 802.11b WEP (Wireless Encryption Protocol) and MAC address filtering. WEP (64-bit or 128-bit) to protect wireless traffic using a key to encrypt the data shared between all computers that need access. WPA (WiFi Protected Access), which is now just beginning to emerge, treat all Weps gaps, so we'll go into a little later in the guide.
Unfortunately, WEP is quite easy to crack with the right software (freely available) and nature of wireless, it is easy for intruders enough encrypted traffic to a cracking software to capture something to work with.

Look up manufacturer based on Mac Address?
I want to incorporate into a piece of software the ability to look up a manufacturer based on a mac address. By googling āmac address lookupā and similar, I have noticed several websites that make this correlation which suggests this data source is available somewhere. Where can I find this data source that correlates a mac address (input) with aā¦

Are MAC addresses unique when coming out of the factory?
According to Wikipedia:
A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment
But how unique are MAC addresses on devices coming out of the factory? I seem to remember hearing a long time ago about how some manufacturers would reuse MACā¦

There is two are interconnected Cisco WS-2950T.
By the one GBIC port on first switch connected a first NIC of bonding interface, and by the one GBIC port on second switch connected a second NIC of bonding interface.
Of course the both switches sees the bonding MAC-address only on one interface (eg it is GBIC on first switch) and all incomingtrafā¦

What happens when two computers on the same network have the same MAC address?
I was reading an article on WEP cracking, which said that filtering MAC addresses was not enough, since there are tools to change what the computer reports as its MAC address.
This made me wonder what would happen if someone uses the same MAC address as another computer on the network?

I have some very trivial basic questions about networking, but I find varying information on that, so I just wanted to settle this.

I run a number of virtual servers on my network and I want to be able to easily clone base installations of Ubuntu Server. I use the VBoxManage command to clone the actual hard disk and I then create a new profile for my VM and copy over the settings of the original VM.
However, when I boot into the cloned VM, there seems to be a network problem.ā¦

IP Address vs MAC addresses
why do we need ip addresses if mac address is enough to identify the machine???
Answer [by Ocelot20]: IP Address vs MAC addresses
Sometimes we donāt want to identify the machine. One machine can have two IPās, IPās can represent things that arenāt machines, the list of reasons goes on and on, Iām sure others will come up with some better ones.
