Why you should use LVM: part 1319755409 in an infinite series

At anchor, we loves us some LVM. It makes managing storage a breeze.

Now, we’ve got one more reason to love it. Because now we have lvmsync.

Like most modern hosting companies, we run a lot of VPSes, and sometimes the chunk of storage they’re on isn’t where it needs to be, so we have to transfer it around. Ordinarily, this would involve a lengthy period of downtime while dd did it’s business and sent the whole LV across a network.

NOT ANY MORE! Now, with the magic of lvmsync we can transfer the bulk of the data while the VM is running, and then do a quick transfer of just the changes after we shut the VM down.

We think our customers will appreciate the reduction in downtime, and I know we’ll appreciate the wonders of LVM just that little bit more.

The Internet Show – Why hosting management is important to your online business

The Internet Show is upon us this Thursday/Friday (27-28 October) and as Anchor has a presence, we are busy preparing for it. I’m happy to announce that we will be presenting a talk at the event about “why hosting management is imperative to the success of your website”. Some of the questions we’ll be asking (and answering) are:

  • What is a system administrator?
  • Do the marketing promises surrounding the cloud make sense?
  • Why are system administrators forgotten?
  • What specifically can a team of specialist systems administrators add to your hosting?

The topic of conversation will center around the fundamentals that make up Anchor, and the approaches that we apply every single day to our hosting business. We will cover the need to have some of the most technically adept systems administratators in the country working to keep your online presence online and available.

We are also exhibiting at the event, so the usual prize giveaways will be on offer at our booth. Drop by and enter the draw to have a chance of winning a new iPhone 4s or romantic dinner cruise for two!

If you have any trouble finding us at the event, simply look up, and you may see a remote controlled clown fish swimming around our booth. Failing that, if you happen to bump into a wandering pirate, he will be able to point you in the right direction.

See you there!

cPanel University?! You’re doing it all wrong!

Today I was minding my own business at my desk when I stumbled upon university.cpanel.net, a site which allows you to obtain “industry certification” for the cPanel Web Hosting Manager.

The first thing I did was check the date; It’s not April 1st. So I sat there stunned for a minute or two, wondering if I should laugh or cry.

Upon further inspection, it actually seemed to be true. You can now go and do an online course and become a certifed cPanel technician!

For anyone who has done business with us in the past, we don’t make too much of a secret that we don’t think too much of control panels such as cpanel or plesk. In fact, we’ve quite openly published our thoughts on this in the past.

That said, trying to think about this a little, I’ve got to ask myself the question — “If you’re building a web-based interface which is designed to allow end-users to control their web-hosting service, then surely expecting certification is doing it all wrong?

Whilst digging further, the actual value of this certification is admittedly some what questionable:

  • The first level testing consists of a total of 18 questions, takes 15 minutes and you need to get 15 of the questions right.
  • You can continue to re-take exams if you fail
  • They can’t actually supply any technical theory or text books
  • The advanced levels of training require you to be proficient in perl — surely if you need to use a programming language to configure your “easy-to-use” control panel, you’ve pretty much missed the point.

As we’ve discussed in the past — cpanel significantly and drastically reduces the barrier of entry to becoming a hosting provider. It allows people who would otherwise not be capable nor qualified to run a fully fledged hosting company and hide behind the pretty exterior of the cpanel user interface. This is scary. Why? some of the approaches and methods which are used by cpanel are considerably questionable.

Some of the observations which we’ve made include:

  • Installing cpanel is like a unix security evolutionary throw back. A newly built machine had an extra 12 processes running as the root user.
  • The security history is so poor that it has a “Scan for Trojan Horses” dialog page.
  • There is no inbuilt firewall management utility, yet it is quite keen to change handcrafted firewall rules added by hand
  • MySQL is compiled without SSL support
  • The update dialog page has people have to chose between 4 different update sources — instead of just one which works.
  • http is run as the nobody user
  • It entirely ignores the Filesystem Hierarchy Standard and stores most files under /usr/local/x
  • If you want to add an SSL certificate for a subdomain that isn’t configured, when you paste the certificate file in, cpanel will successfully parse the cert, extract the correct CN, and map it to the correct user. But when you then paste the key and submit, it’ll bomb saying the CN doesn’t exist. If it doesn’t exist, how did you manage to find a user???
  • It actually comes with /scripts/fix_common_problems

Having courses which explicitly train people up to this level and little further is, to my mind, a grave misgiving. It suggests that anyone can spend some coin on an online test and become sufficiently proficient enough to comprehensively run a entire web hosting company.

Speaking as someone who has had 7 years experience in this industry, providing web hosting services is more complex than simply doing a handful of online tests and installing some random piece of software; doing it well requires the backing of a intelligent, experienced and knowledgeable team of system administrators. Thinking that any piece of software can replace this is not only naive, but a school of thought which potentially leaves the web-hosting industry, as a whole, to be brought into disrepute.

Happy International SUIT UP Day!

For one day of the year, all the Anchorites put away the board shorts and flip-flops, to celebrate in style with Cheap Suits and Expensive Scotch!

In honour of Barney Stinson from How I Met Your Mother, a whole bunch of sysadmins at Anchor went to great lengths to wear a suit to work today! (A certain employee was caught off-guard yesterday and had to purchase a new one)

We know it’s real, because we saw it on the internet

The Anchor team all schmicked up!

Annoucing our US Support Number

In the interests of improving our availability to our valued US clients we’ve recently provisioned a US-based toll-free number which can be used to get in contact with our support team.

This number is:

(888) 250 8847

This number is manned during our standard business hours and will allow you to get directly in contact with any of our qualified system administrators without any holding or difficult to navigate phone systems.

In addition to this, if you have a dedicated hosting environment or purchase a support pack which gives you 24×7 emergency access to Anchor you will also be supplied with an emergency support number.

We would recommend that all US clients record both of these numbers to ensure that they are always able to get in contact with us when required.
