How To: Easily Find What Port a Service Runs On and Vice-Versa

I wrote a python script that allows you to easily ask what service runs on a specific port and vice-versa. Now, I am sure that such a program already exists on our lovely linux OS's, but... I didn't think of that before I started, and haven't found it yet. So if you haven't found it yet either, maybe you'll find this of some use. It's just called getport.

How To: Writing 64-Bit Shellcode - Part 1 (Beginner Assembly)

In this simple tutorial you will be shown step-by-step how to write local shellcode for use on 64-Bit Linux systems. Shellcode is simple code, usually written in assembly that is used as payload in exploits such as buffer overflow attacks.

How To: Get Out of Your AT&T Contract Early Without an Early Termination Fee (ETF)

Earlier this month, AT&T quietly introduced a new "Mobility Administrative Fee" which levies a $0.61 monthly charge to all postpaid contracts. While it's a seemingly small amount on an individual basis adding up to $7.32 per year, with its huge customer base, AT&T stands to make around half a billion from the tight-lipped move. AT&T has stated that the fee will "help cover certain expenses, such as interconnection and cell site rents and maintenance" that's consistent with other phone carrier...

How To: The Good Samaritan's Guide to Returning Lost Smartphones

Sometimes, doing the right thing is way more difficult than it should be, like trying to return a lost smartphone. Despite having the best intentions, it's often hard to track down the rightful owner, especially if the device is armed with a passcode.
