How to find the IP Address of your Online Chat friend

The steps to find the IP address of your Yahoo Messenger chat friend while chatting with him are:
1. Invite him to share a file in the middle of chat with himIf he accepts the file sharing and starts sharing a file there is connection between your computer and his computer starts. This make your computers in peer to peer mode.
2. Open command prompt and type netstat -n command and press enterNow the list of IP addresses to which your computer has an active TCP/IP connection.
[ I recommend you to perform the same task before establishing the peer to peer connection with your chat friend and note the IP addresses at that time. It will help you to easily identifie your victim's IP address. ]
To get more details than the boring IP address ,you can use the following command.
netstat -a
Note:Please note that while you process the netstat command your computer and his computer should have an active connection. If there is no connection at that time you will get only the Yahoo chat server IP address instead of his IP address.

Quickly gather MAC addresses in Windows XP with ARP

When securing a wireless Windows XP network, in addition to using Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA) encryption, you can use Media Access Control (MAC) address filtering.
When you enable MAC address filtering, the wireless access point or wireless router verifies that the network card in the computer requesting access has a MAC address in its filter list before allowing the computer to access the network. This means that you must first obtain the MAC addresses of each client computer. To do so, you might think that you have to manually visit each computer and use the Getmac command.
An easier way to gather MAC addresses is to take advantage of the Address Resolution Protocol (ARP) command. Here’s how:
1. From one computer, use the Ping command to ping each of the other client computers that will connect to the wireless access point or wireless router.
2. Type the ARP command along with the -a parameter:
Arp -a
When used with the -a parameter, the ARP command displays the ARP cache, which stores the IP and MAC addresses of the computers that most recently accessed the system—or in this case, those computers that responded to the Ping command

Shortcut to SHUTDOWN your computer

1. Right click your desktop
2. Create new shortcut
3. Shutdown –s –t 60
4. Then put any name
5. Change the icon
6. Double click the icon your computer will be shutdown with in 60 sec

Do u want to Cancel shutdown - Go to RUN type shutdown –a
