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. 
The problem is bind comes from Red Hat, which has locked the 5.x version to the older bind 9.3. There is a way to get over to bind 9.7 but it is a bit beyond our scope of support. Once you get over to bind 9.7 cPanel will work with it just fine, but you have to move it over. Alternatively, you could just move to CentOS 6.
WARNING THESE HAVE NOT BEEN TESTED BEYOND BASIC TESTING
We can break down all of the web traffic into one of two categories. These categories have nothing to do with the device we choose to access the web: no it’s something much more instinctual than that. For all of our achievements, at the end of the day we are still nothing more than hunters and gatherers.
When we are in ‘gatherer’ mode, we as users ‘know’ what we want…we just don’t know ‘what’ we want. Continue reading →
Backups are a crucial part of any hosting plan. The panic and worry of a site crashing can keep a website owner up at night. For many people, a website is more than a digital presence, a website is means of survival. Whether their site sells widgets or is ad sponsored, losing data is unacceptable. cPanel strives to provide a solution for backups, but the current system is old and needed to be reworked.
I recently got a few minutes with the team and asked them some important questions about the new backup system and how it will make the entire backup process better. Continue reading →
On March 18th, Eric (cPanel’s Director of Development Operations, who’s also my older brother) and I got into a rented Mercedes and turned onto the Autobahn. We had a little over 600 kilometers to drive to Vechta and had to be back that night. It was not even a question of why we were on the road. I was going to meet the person that saved my life; a woman I did not know 6 years ago. Continue reading →
Coming Soon to an EasyApache installation near you – Tomcat 7!
Some things in life get better with age; wine, a classic car, cheese, and fine art. Sadly, Tomcat 5.5 isn’t one of them. With Tomcat 7 an administrator can expect several improved features including memory optimization, refactored clustering, and increased security options. These enhancements will benefit both server administrators and website owners with quicker response time and security measures for Java applications. Continue reading →
Did you look at the Mississippi River last week and shout for Huck Finn to show face? Me either…cough.
We are so excited to be having cPanel Conference 2013 in NOLA. On Thursday we had a chance to do a little bit of scouting and had a quick meeting with some great guys from PingZine. I wish I could tell you all of the venues we checked out, and some of the events that even I was surprised that Erica, our rock star event planner, has the ability to get into the works. On the right column of the above photo are clues to a few of the places we went and looked at. On the left is the stunning lobby of the Sheraton Hotel, where the conference will be held.

We have started on this ‘path’ of redesigning cPanel’s current primary theme called x3. We have even gone so far as to begin calling this new project x4. When Egon is explaining to Winston that the coming psychokinetic activity would be a Twinkie…”thirty-five feet long, weighing approximately six hundred pounds”, Winston simply replies, “Thats a big Twinkie.”
The redesign of cPanel into x4 is, well, a big Twinkie. The home page of cPanel alone has over 65+ icons linking to roughly 120+ pages. These numbers don’t even take into count any additional pages and icons individual hosts have added. Now, almost all of you reading this have gotten used to this enormous Twinkie we call cPanel. Though if you think back and remember the first time you saw cPanel?
So where in the world am I going, talking about a thirty-five foot long Twinkie and what does it have to do with x4? Continue reading →

Important: This setup is considered to be unsupported by the cPanel/WHM team. Please note that once cPanel/WHM no longer maintains MySQL on your system it is on the Systems Administrator to manage and maintain any updates and maintenance on the database software. We recommend only experienced systems administrators perform the above and we are not responsible for any possible data loss.
Below you will find some steps on how to affectively stop cPanel/WHM from maintaining MySQL and begin utilizing Percona for any and all database activity on your server. You can find the Percona website at www.percona.com.The guide found below is based around utilizing the new RPM tools we provide in 11.36. Continue reading →
