Today, we employed some wizard power tools to manage our machine park. Most notably, we learned how to connect two VMware ESX servers underneath one management umbrella and then how to throw virtual machines — even running ones! — from one server to another.
For a live migration to be possible, some rather obvious (and, while [...]

Most of today for me went waiting for actually installing a virtual machine and nodding out while the story was about managing storage and the infrastructure. In perspective, infrastructure management is rather neat, and storage systems aren’t exactly my turf. At least not yet. I mean, i kind of get the gist of it, i [...]

Cacti is a free network monitoring and graphing (”trending”) tool, which i’ve managed to install on a computer at work. The idea is that eventually i will have a portable network monitoring tool that is both easy to physically lug around and reasonably easy to plug into a new network and let it do its [...]

This is one of those days. Since i were on a course for a week, my Windows domain login expired. I managed to log in to my computer this morning but after lunch, my screen was locked and so was my account. So i try to give A and B, our friendly sysadmins, a [...]

Kuluneella viikolla ilmestynyt Aku Ankka oli riemastuttava yllätys näin käytettävyydestä ja tietoturvasta (käytettävyys + tietoturva = hcisec) kiinnostuneesta ex-akateemikosta. Vissiin joka tarina kertoo jotenkin tietoturvasta. Otetaan tässä luupin alle lehden avaussarja Kuurakaara.
Pelle Peloton keksii vedellä toimivan auton Roope Ankan markkinoitavaksi (jutun toisessa ruudussa seisoo valloittava pingviiniparvi tiirailemassa keksijän ohikiitävää ilma-alusta!). Fysikaalinen epätodennäköisyys [...]

As a small exercise in geekdom (when i probably should have been to bed already) i installed Xubuntu 6.10 on a one gig Kingston Mini-Migo USB flash drive. Yeah, it’s pretty small :). Instructions are here.
What i didn’t get running straight out of the box was the wireless network, which was handled with a [...]

On KDE Linux, i have File Size View to show me how much fat different branches of my directory tree are (i also have du -h –max-depth=somenumber but that’s another story). On Windows i have… nothing. That is, until a colleague of mine pointed me to TreeSize Free. Sure it ain’t as elegant, but hey, [...]

Bob Cringely skrev om den här lilla datorn som han byggt in i sin familjebil i syftet att fungera som videoserver för odjuren i baksätet. Den är pupsig (“kawaii!”). En sån vill jag ha. Den klurige Bob streamar videomaterialet till Sony PSP-spelkonsoler som ungarna får hålla i sina händer så att de inte [...]

I’ve added a thing or two on bun-bun, my unslung NSLU2. First of all, there’s another 0.4T of storage on it, now making it a 0.6T system. Moreover i installed a few programs to make use of that disk space.
rsync is a senslessly nifty little suite of programs to keep a source and a target [...]

I’m a bit behind posts but let’s not make that a problem. A week or two ago, a new computer entered the family: a Slug, or properly, a LInksys NSLU2 NAS adapter thingy.
The Slug is basically an adapter between one or two USB hard (or flash) drives and a wired Ethernet. Or so it [...]
