Power of PING

In our respective interactions with various networks accessible to us.....as administrators we keep pinging so many IPs for testing the connectivity at various times like ping 192.121.23.1 etc....and we get a response...but ping it self has so many switches that most of us hardly use......i came across a chart today that in a summarized form tells the switches of ping command with examples and a brief explanation.....sharing here with you...thanks http://www.activexperts.com

ping -c count	ping -c 10	Specify the number of echo requests to send.
Ping -d	ping -d	Set the SO_DEBUG option.
Ping -f	ping -f	Flood ping. Sends another echo request immediately after receiving a reply to the last one. Only the super-user can use this option.
Ping host	ping 121.4.3.2	Specify the host name (or IP address) of computer to ping
ping -i wait	ping -i 2	Wait time. The number of seconds to wait between each ping
ping -l preload	ping -l 4	Sends "preload" packets one after another.
Ping -n	ping -n	Numeric output, without host to symbolic name lookup.
Ping -p pattern	ping -p ff00	Ping Pattern. The example sends two bytes, one filled with ones, and one with zeros.
Ping -q	ping -q	Quiet output. Only summary lines at startup and completion
ping -r	ping -r	Direct Ping. Send to a host directly, without using routing tables. Returns an error if the host is not on a directly attached network.
Ping -R	Ping -R	Record Route. Turns on route recording for the Echo Request packets, and display the route buffer on returned packets (ignored by many routers).
ping -s PacketSize	ping -s 10	Sets the packet size in number of bytes, which will result in a total  packet size of PacketSize plus 8 extra bytes for the ICMP header
ping -v	ping -v	Verbose Output. Lists individual ICMP packets, as well     as Echo Responses

POWERFUL THAN ADMINISTRATOR ACCOUNT : SYSTEM LOGIN

1.  So here is something unheard to those who thought that ADMINISTRATOR was the king of the respective PC account.So for those who think so...ever thought why r u unable to fiddle with system files when u r the owner... that's because there is a SYSTEM account over and above the administrator who can delete the administrator account!!!!yes u read it right....so how do u get to the system account.I am giving it a step by step attempt here with screen shots!!

2.  Firstly...get to your desktop and see ur user name...mine is windowsxp ie a user account with admin priveleges as shown below :

3.    Secondly,get to the command prompt and create a schedule to run cmd.exe as follows :

at 14:51 /interactive “cmd.exe”

*** The time mentioned here can be a minute or two ahead of whats the time u doing this action.

 4.   You can check schedule by typing “at“ and hitting enter after the above step.

5.    Now Wait for the time you set for the schedule and u see that cmd.exe would be launched at the specified time and a subsequent command prompt windows will open automatically.

6.    Now go to ur desktop without closing any window and reach the task manager and kill the explorer.exe file under the process tab.

7.    Close the first cmd window and not the second one.

8.    Reach the root directory by pressing cd\

9.    Type start explorer...thats it...now u logged in as the System.....as shown:

 10.   Point to note :

- This is only for educational and info pupose.
- Never attempt it on a live system.
- Always do it on a virtualbox or Virtual machine or virtual PC.
