I am going to expose an important topic on hacking knowledge that some of you might know and most of you don’t. When you’re going to hack a computer or server on the Internet, you won’t want your IP address to spill out. That’s because your ISP could easy trace you by two simple information which is the time and IP Address. So you’ll need to use proxy or even chains of proxies to avoid being directly traced by the victim’s firewall. If you think you’re safe hiding behind a proxy server, bad news is most proxy server has logging enabled and your IP address is definitely listed in the log file when you’re connected to it. It is possible that the administrator of the proxy server passes your information to your ISP and you’ll still get caught at the end of the day. Don’t forget, there are still some other important information that can be obtained from an IP Address if a person knows what tools to use. One of it is your network adapter’s MAC address.

1. May 18, 2015  Your Mac may have more than one active network connection, including multiple Ethernet and Wi-Fi ports. If more than one are active and connecting to the same network, then your Mac may be broadcasting its services more than once. Therefore, try disabling all but your main one in the Network system preferences (uncheck the unused ones).
2. It is available on many operating systems (Linux, Windows, Mac OS X, BSD, etc.) Nmap is used to gather information about any device. Using the Nmap, we can gather information about any client that is within our network or outside our network, and we can gather information about clients just by knowing their IP. Zenmap Tutorial.

May 05, 2010  I am trying to network the two macs that I own together. By that, I mean I would like each computer to be able to access all of the files on the other computer. When I purchased the second Mac, the guy in the store showed me quickly on the floor models how easy this was, but I.

Every network card contains a unique code called MAC address that is permanently assigned to it, similarly like every computer requires a unique IP address to be connected to a network. Although these information can be configured to have the same, it would cause conflict and connection problems. To view your network card’s MAC address, just run the command “ipconfig /all” in command prompt and refer to the value of Physical Address.

One thing you should know is the MAC address on your computer’s network card will not get passed out to the Internet so there is no way a website or an Internet server can capture this information. Only your Internet Service Provider (ISP) can detect the MAC address of your modem or router. So basically your ISP is capable of tracking your location by your IP address, time and the MAC address of your modem or router.

In another scenario, some people may still be using WEP encryption for their wireless network because some old devices don’t support WPA. WEP encryption is very weak and can be cracked in less than 5 minutes using BackTrack Linux. Most of the time they’d also enable a second line of defense which is the MAC address filtering to only allow authorized devices to connect to their wireless network but they’re wrong. A hacker can easily find out the authorized MAC address, change their network card’s MAC address to the authorized ones and poison the ARP cache to prevent the owner’s machine from connecting to it. Here’s an example of Belkin Play Max F7D4401 v1 router. It has a MAC Address Filtering feature where you can set up a list of allowed clients and use the wireless connection.

Other than that, some time limited shareware such as Hotspot Shield that uses your MAC address to keep track of the free usage. If the trial period has expired or is pending to reset every month, you can easily bypass this restriction by changing your MAC address. I bet by now you should know the power of spoofing your MAC Address. MAC address can actually be changed directly from Windows but the easiest way is to just a free program called Technitium MAC Address Changer.

To change your MAC address, run the program, click the Random MAC Address button followed by the Change Now! button. The update takes effect immediately without a reboot and stays intact even when you boot up the computer tomorrow. To restore back your original MAC address, click the Restore Original button on Technitium MAC Address Changer program.

To manually change your MAC address in Windows 7 without using a third party software, go to Control Panel > System > Device Manager.

Click on it and you can specify your own value with any random 12 characters of letters and numbers.

The Technicium Mac address changer has certain restriction in some cases (particularly Wireless connection) such that we should use only ’02’ as fist octet of mac address (as you can see a checkbox in the tool). So, it seems it is not possible to completely spoof your mac address as another PC’s mac address. May be we can play with, by just hiding behind some random mac address.

spoofing the MAC randomly every few minutes may be more useful.

If you’re behind a router, your ISP only sees the router’s MAC addy. That’s the one you should change.
Regardless, if you have a home broadband connection, you might have a hard time arguing with your ISP since they tie your IP to the modem id.

Using the Mac's built-in file sharing capabilities, you can open and copy your files with other Macs and Windows PCs on your network. You can also specify individual users you'd like to share files with, and individual folders you'd like to share. You can even restrict those users' access, making it possible for them to only copy files, or providing them with the ability to write new files too. While AirDrop is convenient, file sharing is where the Mac's networking power really shines.

How to share your Mac files on your network

1. Open System Preferences.
2. Click on Sharing.
3. Check the box next to File Sharing.
4. Click on the + button under Shared Folders to share specific folders.
5. Click on the + button under Users to specify particular users to share files with.

6. The Options button lets you share files using SMB, a common Windows file sharing protocol, and AFP, or Apple Filing Protocol, a legacy technology supported on some older Macs.

How to access shared Macs on your network
