For years I’ve been using smartmontools on my linux-based machines. What I’ve absolutely LOVED about it is the advance notice I’ve had of hard drive failures. Two consecutive Decembers I received an email from my server claiming that a drive was dying and had time to replace them rescuing the data. (Although the first one was falling to pieces as I copied.) If I had not know until I NOTICED a problem I would have likely lost a good amount of data and had a long rebuild process from various backups.

Yet another domain tools site.
For a while dnsstuff.com has been my favorite dns tools web site, but there are others. Recently I was pointed to domaintools.com.

Wikipedia download revisited
A while ago I wrote about various ways to have an offline copy of the wikipedia. Yes, I know there are credibility issues with wikipedia, but taken with a few grains of salt and objective thinking it is one of the single most useful references online. (I don’t count search engines here – they link to other stuff – i.e. no – you can’t download google. ) So, why would anyone be interested in having it copied offline? Isn’t the great benefit that it’s constantly updated and “fresh”? Well…. if you assume that 24/7 highspeed internet access is a fixed constant… i.e. we’ll ALWAYS have an internet connection anytime anywhere, then… there would be no good reason… but..

Drive images – filling free space with zeros
So, one of the things I’ve been doing is drive imaging. I’ve got 3 systems that are to be identical (based on, of all things Freedos…) So, I thought it was a perfect opportunity to dust off cloning/imaging software. So, I’ve been using the excellent g4l (ghost4linux) which is now up to v 0.22 (I make use of this for trying to rescue failing hard drives too as it includes dd_rescue). Anyway, the new machines have 80GB drives and the lzo compressed images are running ~450MB…. but one of my questions was making sure that it was as small an image as could be. I found that there are a few ways to squish the image file more and that it mostly revolves around filling the empty drive space with zeros.

Instlux – install linux without rebooting to a cd
A few days ago I was researching possibilities for linux boot without rebooting to a cd. I found something interesting in instlux. Essentially, it’s a windows installer style download that can bootstrap and install a linux distribution (looks like Linkat, OpenSuse and Ubuntu are currently supported.) I’m curious to actually try this out in the near future as it looks inteesting (you can choose either cd or network based installs).

Really not wanting to sit at the desk….
So… it’s ~70 degrees out and springish I have network cables draped over my desk to support a couple systems that I’m imaging right now and am really not wanting to sit here, but… I do have a few things to “clean out”…

Opengroupware install on Ubuntu 6.06 Dapper Drake
One recent task was install opengroupware on a dapper drake 6.06 install in a virtual machine. I followed the instructions found here and ran into a slight problem. The default install from Ubuntu does not have apache in the enabled repositories. (Apache2)… following the intsructions given I first added opengroupware’s (debian sarge) repository (more…)

Vmware server install on Ubuntu Dapper
I thought I had already posted this, but I looked the other day and didn’t find the article, so I’m posting it now… if it’s a duplicate, sorry… I’m still using Ubuntu’s Dapper Drake 6.06(.1) as a base install for many things… the Long term support idea fo rthe server “stuff” is somewhat reassuring and I don’t want to be chasing minor revision upgrades every 6 months. But, there is another reason, a lot of the installs I’ve done have been a base for VMWare server and there are some very good (and clear) how-to’s in that arena….howtoforge has a good walkthrough that I’ve used as a starting point….
