How to disable WPS on the Netgear WNDR4500 Router

About: WPS stands for Wi-Fi Protected Setup and it is a wireless networking standard that tries to make connections between a router and wireless devices faster and easier. It works only for wireless networks that have WPA/WPA2 security. That’s great, however there is a problem with WPS, it can easily be cracked and allow a hacker access to your home WiFi network.

WPA2 security is very secure and there really is no way of hacking WPA2 without using a dictonary attack which can take months depending on the hardware you are using to bruteforce. It can also be a waste of time if your password is very long and includes many special characters, however if you have WPS enabled on your router (which it usually is by default) there is a faster way to hack your WiFi and it can be usually done in a maximum of 12 hours.

How to schedule Cron Jobs on the Raspberry Pi

About: I have recently been working on a MMORPG turn based text game and needed a way to run a php script every 2 hours to generate a turn. Since I use the Raspberry Pi as a LAMP server for testing out my game before releasing official updates I figured it would work well as a cron job to call a website page every 2 hours.

You can schedule many types of cron jobs using your Raspberry Pi. Cron is basically the Linux version of the Windows Task Scheduler. You can schedule commands to run at certain times of the day or only run once a month. The shortest time a cron job can run is 1 minute in between commands. If you need a command to repeat every 30 seconds then a cron job will not work.

Objective: To create and schedule a cron job using the terminal on the Raspberry Pi

Material: You will need the following:
