How to Use the NETSH Command to Change from Static IP Address to DHCP

You can use the netsh command in Windows 2000 to script the process of changing a computer from a static Internet Protocol (IP) address to Dynamic Host Configuration Protocol (DHCP) or vice versa. The netsh command accomplishes this task without the need to restart the computer. This feature is particularly useful for laptops that move from one environment to another, when it is necessary to use statically assigned IP addresses at one location and DHCP assigned IP addresses at another.
To switch the specified adapter from a static address to DHCP, type the following command:
netsh interface ip set address “Local Area Connection” dhcp
NOTE: Typing this command changes the interface named “Local Area Connection” to DHCP.
To display all of the adapters in the computer with their current IP addresses to determine the correct adapter name, type the following command:
Netsh interface ip show config
To change to a static address, type the following command:
netsh interface ip set address “Local Area Connection” static ipaddr subnetmask gateway metric
NOTE: Replace ipaddr with the static IP address, subnetmask with the subnet mask, gateway with the default gateway and, if necessary, metric with the appropriate metric. The following example changes the interface “Local Area Connection” to a static address of 192.168.0.10 with a subnet mask of 255.255.255.0, and the interface has a default gateway of 192.168.0.1 with a metric of 1:
netsh interface ip set address “Local Area Connection” static 192.168.0.10 255.255.255.0 192.168.0.1 1

Now you can breathe liquid!

DIVE DEEP The recommended absolute limit for recreational SCUBA divers is just 130 feet, and technical dives using Trimix bottom out at 330. Even then, you’ve got less than five minutes at depth before requiring monitored decompression to avoid getting the bends (the not-scary word for when nitrogen dissolves into your tissue under the massive pressure of the water column, is ejected into the bloodstream during ascent, and you die of a brain embolism). Interestingly though, once your body hits its nitrogen saturation limit, it doesn’t matter if you stay down for an hour or a month; your decompression time effectively maxes out. This technique, known as saturation diving, is how recovery divers working on the K-141 Kursk were able to spend hours 300 feet below sea level (amidst 10 atmospheres of pressure) and how the crew in The Abyss were able to do their jobs. LIQUID AIR Perhaps the best-remembered scene from the 1989 Sci-Fi classic The Abyss is when Ed Harris’ chara...

Don’t like people to know you’ve read their Whatsapp messages? Here’s how to get around it.

The honor of having one of the most misinterpreted features in the world of tech startups goes to Whatsapp – specifically, the check marks that appear next to any message sent. Many initially guessed that two check marks meant that the recipient has already read the message, but that turned out to be incorrect Here’s what those check marks really mean: one tick to show that the message has reached Whatsapp’s servers, another to inform the user that it has reached the recipient’s phone. Now, there’s a third layer of information in the form of blue check marks, indicating that the recipient has indeed read the message. In the interest of privacy, Whatsapp had not so long ago introduced the option to hide the ‘last seen’ notification that informs the other party when that person was last on the messaging platform. The introduction of the blue check marks is strange, given that this brings back the social pressure to reply – what many users consider an intrusion of privacy. ...

Can I determine if my computer has a key logger installed? – YES!!!

Detecting keyloggers is as simple as looking in the right place (which may or may not be simple depending on your viewpoint). The problem is knowing what to look for and where. What follows is a non-exhaustive few things you could do to check for keylogging modules. Firstly, the obvious easy way to build a keylogger is to use DLL Injection which can be achieved a number of ways. Most of these will result in a DLL showing up as mapped to the process’s address space. Take a look at this picture: What is the topmost entry in that list? It’s a pyd , or python extension, file. I’ve been messing with python-implemented COM servers and as a result, the DLL is loaded into Windows Explorer’s address space. DLL Injection of the keylogging variety will load its DLL into all of the target address spaces – can’t capture everything if you don’t. So one thing to look out for would be strange DLLs you cannot attribute to products whose purpose you know. They’ll show up in this list for...
