Keeping systems patched is one of the most basic security protections available. However, ongoing scanning of web hosts in Australia and New Zealand suggests that many servers are not being regularly updated or using basic security mechanisms.


Databases underlie most other applications, so it's no surprise that database-as-a-service options are becoming more common. But if you're thinking of rolling out databases in a cloud environment or consuming them as a service, there are some important caveats to bear in mind.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.


We've known for decades that the available pool of IPv4 address was eventually going to dry up, but despite numerous warnings usage of its successor IPv6 is still minimal. Why haven't we migrated yet? Geoff Huston, chief scientist for regional internet registry APNIC, suggests that the answer is that carriers are too cheap to make the switch and are happy to rely on network address translation (NAT) systems instead.


In the cloud computing era, effectively managing servers and systems is more important than ever. Follow these basic principles to ensure that your workplace systems run smoothly (and advance your own career in the process).


If you are already running servers in a virtualised environment, then shifting into a cloud environment might seem like a relatively trivial step. However, there are some simple principles worth remembering to ensure the process happens with minimal hassle and that you can justify the costs involved.


IP is now the de facto standard for any kind of networking -- so much so that many sites blindly implement it without any understanding of what went before. However, even if your business is running happily on IPv4 and you have a migration plan for IPv6 in place, understanding the history of how we arrived at using those standards can help you manage your own network better.


Simple Network Management Protocol (SNMP) is one of those standards that is implemented almost everywhere but ignored by almost everybody. While there are more sophisticated methods available for monitoring and managing network performance, SNMP survives partly because it remains the main option supported in many pieces of specialised networking hardware.


If you want to train large groups of students on how to use and deploy networking equipment, you'll need to rapidly redeploy fresh system images as each new class comes in. That sounds like an obvious case for using virtualisation, but there are some traps to be aware of before pumping out those virtual machine images.


After almost seven years in development, Samba 4.0 was officially released in late 2012, adding Active Directory domain controller features to the popular interoperable file server solution. So what happens now?
