Edit: This information is old and may longer be relevant. An open resolver is a dns server, which will allow a recursive query of an arbitrary domain from any IP address. An open resolver can be used in a reflection DDoS. Only Subnets controlled by the organization should be allowed to conduct recursive queries on a dns server.

On February 27th, I will be joining fellow Internet Infrastructure Coalition (i2C) board members for a day to meet with various Congress and media outlets on Capitol Hill about our efforts to preserve our Internet freedoms. This gives cPanel the chance to join in the effort to protect the legislation that will one day affect you, hosting companies, and even cPanel. …

Hey there! In this instance of The Admins Toolbox, I’ll be discussing the tcpdump utility and some common uses. Sit back, crack open a frosty beverage of your choosing, and let’s learn about packet inspection for fun and profit. 🙂 Tcpdump is by no means a new program. Written by Van Jacobson, Craig Leres, and Steven McCanne, while working at Berkley in 1987, tcpdump’s popularity quickly rose due to its high caliber of …

In this article we detail the steps required to remove the Getting Started Wizard. Someone may want to do this for the purpose of delivering servers in a “Configured” state. …
We really have no information available on how to write WHM Plugins. I have had 3 people ask me in the past 48 hours on how to write them, so I thought I might want to consolidate and post this knowledge. A WHM plugin is merely a simple CGI application that has a couple of special comments in it to handle how it is displayed. Any CGI language can be used here, however only perl …
