Exim Queue Management Tutorial

So, you have got yourself a shiney new dedicated or VPS server with cPanel or DirectAdmin or some such installed. It probably won’t be long before you have to start checking the exim mail logs and the exim mail queue to trace problems being encountered by customers.

I have put this article here more as an aide-memoir than anything. If anyone finds it useful, I’d love to hear from you!

Respect the exim queue

One of worst things you could ever do as an admin, when finding a mail queue with hundreds or thousands of frozen or delayed messages in it, is to simply clear the queue. DONT DO THIS! You might just as well not run a mail server at all. The messages you remove in this way will just vanish without a trace – your customers and the people they communicate with won’t have a clue what happened, and your service will soon be viewed as unreliable.

Sadly, many inexperienced admins use the graphical UI to do just that – because it’s easy. However, with just a few simple commands, it can become possible to inspect and manage the queue with much greater elegance.

So, read on to find out how Exim queue management can be done from the command line. Read More…

Website Uptime Monitors Review – Choosing the Right One

For my sins, I work part-time for other hosting companies, and one of the most common misunderstandings I encounter is when someone will swear blind their website is down when the truth is that their ISP is just suffering some temporary routing problems.

Customers come in all shapes and sizes, and degrees of ability and understanding of how the internet works, and the more savy website owners now use some form of website monitoring to make sure that us naughty dishonest web hosting companies are playing our part in their success.

Some folks spend more on the website monitoring than the hundred quid a year they are prepared to spend on the website hosting itself – hosting that enables their business to rake in a small fortune (but that’ a rant for another day!). So read on to understand more about uptime and availability. Read More…

How do I trademark a company logo?

Registered Trade Mark indiciaProtecting your corporate identity is becoming more necessary than ever. In an increasingly competitive and, arguably, immoral capitalist system, companies are becoming only too willing to try and steal some of your business by cloning your “look and feel”. Even worse – and this happened to yours truly – a new company that looks like it has a good name might have the rug pulled from under it’s feet by the big boys registering your name as a trademark before you get the chance to establish yourselves!

The difference between TM and ®

We’ve all seen the little TM and ® marks adorning logos for years, but what do they mean?

TM, meaning Trade Mark is simply the owners assertion that their product, service or company are unique. There is no real legal validity to this, other than that the brand may have been notoriously well known for many years. Whether or not the user shows the logo with the TM is largely immaterial – the claim to ownership of a brand name or logo will always be stronger, the longer you have used it unchallenged, whether it has been legally registered or not.

®, meaning Registered Trade Mark means that the items in question has been registered with the Patent office (or IPO Intellectual Property Office in the UK). It has legal clout right from the word go. Read More…

Linux – Move or copy the contents of one directory into another

Linux TuxThe way Linux expands it’s wildcard, or globbing characters, can be confusing at first and even tasks as simple as copying a few files can sometimes turn into a learning exercise. It is sometimes necessary to move or copy files in bulk from one place to another. There are several methods for doing this in Linux, depending on which tools you have installed (Obviously, tools like rsync or unison might be better in many cases), but for this article we’re just sticking to mastering the cp command.

It’s important to understand how Linux sees the contents of each directory, because there are two special entries within each directory which people often overlook – plus there is the issue of hidden dot files – files whose names start with th dot – e.g.  .htaccess

# ls -a1
./  << This is the current directory hard link
../  << This is the parent directory hard link
new/
old/
