Anyone that’s setup software raid on a system with multiple storage adapters has probably run into this kind of issue, but I thought I’d mention it. Last weekend I built a machine to replace my server (the server was to be captured into a VM). The main system was going to be installed [...]

One of the tools I looked at having for my expanding kit has been a usb wireless adapter that would work with minimal install on Windows/Mac or Linux. As you can imagine…. it’s not as straightforward as just getting one that’s compatible with Windows…. well, after much searching I found the D-Link DWL-G122 802.11g [...]

I’ve noticed several times in the last week a server of mine that is using postfix has rejected messages due to a failure in the lookup at relays.ordb.org. At first, I thought this was just a false positive in the database at ordb… but this morning I finally “caught it” while it was happening [...]

sfdisk -d /dev/hde > /raidinfo/partitions.hde
So…. I’ve now got a good snapshot [...]

I like nx server and client, it can really make good use of low bandwidth connections to get a gui link. But, by default it’s quick and easy to setup gnome and kde login sessions within nxclient, but if you’re using xubuntu then you will need to setup a “custom” session and the command [...]

Not really, news, but I was reminded again this evening that mail is not available at the command line in recent default installs of Ubuntu (or kubuntu /xubuntu). If you’re like me and make use of this for scripting notifications…. you’ll need to sudo apt-get install mailx (and a MTA like postfix.) Mailx [...]

ah… the joys of *nix utilities…. I’ve just successfully tested a “capture” of a live, running system into a virtual disk image. No, I don’t mean that I booted up with an imaging utility. I took a live, booted and logged in system and imaged the primary hard drive that it was [...]

I’ve had a machine for quite a while that I’ve been working on as a “backup server”. My goal with it is to have a RAID1 setup with two 250GB drives and I also wanted USB2/firewire functionality so that I could even add a USB drive to the array for the purpose of having [...]
