Open Resolver Handling with Bind on CentOS 5.x cannot Update to 9.7[Workaround][Old]

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. [1] The problem is bind comes from Red Hat, which has locked the 5.x version to the …

Capitol Hill & the i2C

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. …

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 …

WHM Plugins

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 …

Using WHM remote authentication

One thing that I have noticed while working with other people developing software that interacts with WHM’s XML API is that they always use basic HTTP authentication. It is okay to use basic authentication, but it is held to the same security restrictions in place for people using browsers. When working with cPanel in a remote fashion, having to work around these restrictions is unnecessary. Inside of our dns clustering system, we developed a …
