A recent number of attempted break-ins to a few machines I manage has had me thinking again about the overall security of the machines, and how to get a better handle on what’s going on. This isn’t something new – anyone managing internet-facing systems ought to be aware of the dangers, and how to mitigate ...
It’s been a while since I posted on here. It’s been a busy year – for reasons both good and not-so-good – but I’ve got a few ideas that I’ll be posting about over the next week or two. For those interested in amateur radio (or wonder what it’s all about) – I also have ...
Using NFS between two machines on the same network is usually free of hassle, so the default behaviour – on Linux, at least – is fine and can be left as it is. However, in a commercial setting (such as the ones I manage in my day job) it’s often the case that the machines ...
I’m currently studying for my amateur radio Foundation license, and as part of this I’ve been playing about with electronics a bit – something which I never really learnt properly when I was younger. There’s plenty of free electronics simulators (such as gEDA), and some not-so-free (Multisim), but the learning curve for them is perhaps ...
Just a short one – and the first post in a while – but I’ve come across www.hamtests.co.uk, which contains a guide to the syllabus for the exam for the Foundation license – as well as mock tests for the exam itself – which I’m hoping to do in the coming weeks. The site’s not ...
Another repost, this time from last year when Peter Davies was elected Mayor of Doncaster. I’ve noticed this is being linked to a lot, so here it is (Update (12.06.2009): I’ve had an email from Toby Foster’s brother, who’s pointed out that where I originally transcripted Toby as saying “About right”, he actually says “Well ...
Doncaster is my home town, and it’s also where I’ve lived for all of my (almost) 28 years since I popped (!) into being at Doncaster Royal Infirmary in the summer of 1982. For those unfamiliar with geography in the north of England, Doncaster’s a fairly large town (with a population just under 300,000) in ...
Update: I’ve not tested myself, but the comment from Sombunall below points out that package names for the TFTP server and the DHCP server have changed since I wrote this post! It’s often the case that there’s no easy way of installing a machine that doesn’t have any removable media. For instance, I have an ...
So the little birdies were correct – Google have just updated Streetview for the UK. They’ve spent the last year or so photographing the length and breadth of the country, and now it’s all there to see, including such wonders as this blurry-faced chap:- Yeah, that’s me, on my way out to work. I’ll ignore ...
The standard network tools ifconfig, netstat and route will be familiar to anyone with more than a passing interest in UNIX or any of its derivations. Linux is no exception, and if you hop on to your nearest Linux machine, you’ll find these installed. However, for the past few years ifconfig and its ilk (often ...
