Wow…. Let me just say that I have typically been inundated with junk mail on my primary address. It’s associated with this domain and has been hosted in an older sendmail setup for quite some time (not really by choice, but because that’s what was installed on the old vps.) I’m currently migrating to postfix which I’m a bit more familiar with and had used successfully to at least tag my junk mail as SPAM for sorting at home. Well, my older postfix system didn’t have too many options to add on and tweak and so this weekend I’ve invested some time in migrating the main mail server over to a newer postfix install with amavis and postgrey and a few other tools.

Rsnapshot – ERROR: /usr/bin/rsync returned 127 while processing
Just a quick note for what is really a simple fix. I have been using rsnapshot to back up several machines lately. If you haven’t taken a look at rsnapshot on linux for managing snapshot backups (where only the changes get backed up after the initial run….) it’s definitely worth a look.
Anyway, I had recently added a new system to be backed up and was seeing the following error from my Rsnapshot log…. ERROR: /usr/bin/rsync returned 127 while processing hostname….

Linux Software Raid Notes – Replacing Drives
This post is going to be somewhat of a “link dump” for me of some pages that I’ve been perusing lately. After playing with RT (request tracker) – I added a few ticket items for the home network. Now, if you’ve been a longtime reader and sorted through ALL of these posts here you’ll know that I’ve made use of software raid on the home systems. Why? Linux software raid seems fairly reliable (so far – 2 years +). It doesn’t depend on a specific piece of hardware. In short IF the worst happens and the array fails I should be able to retrieve data from an individual drive more easily than if it were hardware raid. I’m using Raid Level 1 (cloning/mirroring) and ext3 is the filesystem on top. I’ve had some slight problems with one drive in both the Desktop and server arrays and both arrays had been degraded for some time. My goal was ultimately redundancy and to eliminate the disruption that hard drive failures have given over the last few years.

Recovering a Split BiggieFile from a MondoRescue Backup
Once upon a time I wrote of manually extracting a file from a mondorescue backup. Sometimes it’s just easier to do that, than have mondorescue go through 30 some cds or dvds just to find one file. (Not to mention the fact that the iso’s aren’t burned to disc but are just stored on a usb HD.) So, I’ve just had the opportunity to try to restore one of the “biggiefiles”. Mondoarchive attempts to split huge files up into smaller slices for archiving. The size is something that I think is configurable, but I haven’t made any changes from the default.

Various Notes | Morse Code Ringtones | Java updates | More Pages on the Way
Sorry for the vague title, but there are various thoughts floating around at the moment. The first is a big thanks to the support at Westhost for recovering my VPS over the last weekend. I had started an automatic upgrade of wordpress in one of the sites hosted in this vps, it hung… so I ssh’ed in and found the vps was essentially ruined – it managed to wipe out quite a bit. I’m not sure if it was a coincidence or if the wordpress upgrade was really the culprit, but it managed to destroy quite a bit. The support at westhost though had things back up within 24 hours. It wasn’t just a matter of the site and database getting deleted, but files in /etc were gone (mail configuration hostname resolution wasn’t working, scp wasn’t working…. it was trashed in a bad way.)
Anyway, I’ve still been tinkering with the free morse code mp3 ringtones. In particular I’ve been tinkering with the Text to morse code mp3 generator. I’ve been trying to add utf support. The backend generator does interpret morse for utf characters, I’ve managed to get a way to decode the url encoding if they’re placed in the text box, my big challange at the moment is the file name. I have to truncate the filename so that it’s not too long, but most everything I’ve tried to truncate counts bits instead of characters. Some, even if I tell it to count characters will assume that 1 character=1bit and I wind up with some of the utf characters cut short which gives unusual filename results. In the testing version of the script I’ve just decided to sanitize things by replacing an extended character with an x….

Morse Mp3 Ringtones
I’ve spent a bit of time over the last week putting some scripting together to build a new website. The site is morseringtones.com and as you might imagine there are morse code mp3 ringtones available there for download. I’ve put together a list of over 9100 names and there are 4 ringtones available for each name. These are played at 4 different speeds in morse code. For the quicker speeds the names are repeated multiple times to make sure you have a better chance to hear them if you’re using them on a cell phone. I’ve put things up to where you can submit ideas for further names if you like. I may be adding prosigns at some point in the near future and at some point may make it possible for people to go ahead and generate custom morse ringtones from a web interface. So if you want a morse code ringtone for your phone step over and take a look.
I’ve also bundled up the whole collection of them for download via lulu.com, more details can be found on the Purchase morse mp3 ringtones colleciton page.
In the future here I may detail some of the scripts that I’ve used to build this site. It’s all built on a linux server ( the generation of 9100 ringtones at 4 different speeds took about 6 hours.) I’m sure the scripts could have been designed differently but was quite proud of putting together the process for making the whole site so that future maintenance is minimal.
Anyway …-.-

Ubuntu 9.04 Jaunty Netbook Remix on an Acer Aspire One ZG5 trackpad issues
Recently I had the opportunity to work on an Acer Aspire One netbook. It’s rare that I get the chance to work on a linux desktop system for a client. Most of my desktop users that I support run Windows (although I primarily run linux on my machines.) I get to do a fair amount of server level work with linux variants, but this one, being a desktop install, intrigued me.
The issue was that the buttons on the trackpad didn’t work. She also indicated that she had tried a usb mouse and those buttons didn’t work either. As I looked at it, I had already spent some time browsing through bug reports getting ideas on what might be the issue. It behaved exactly as she described and so then the real fun began.

Zarafa Exchange Server replacement and Postfix Integration for multiple domains with unique users
So, I’ve spent some time recently working with Zarafa. It’s an exchange replacement that has a completely open source version as well as a version with licenses for outlook if you want that level of integration. It’s web interface looks good and is an improvement on Exchange server’s capabilities with a non-IE browser. Anyway it can install on a linux server and integrate with several different MTA’s. Our choice was postfix since that was already installed for the purposes of processing forms on a webserver on the same host. Outgoing mail “just worked”, but postfix needed a bit of configuration to make the incoming mail work.

MPlayer Video Stream Lagging Audio
On my (somewhat older) laptop, I’ve noticed that MPlayer sometimes gets the audio and video out of sync. The audio is moving faster than the video. I’ve noticed this in octoshape streaming as well as in playing standalone videos.
I discovered a quick fix to this is to use the d hotkey on the keyboard. This toggles between frame dropping modes. By default mplayer tries to draw every frame it receives, but toggling to either framedropping enabled or framedropping hard can help keep the video up with the audio track. I’ve found this has made my octoshape streams usable again! (Usually I just make use of the framedropping enabled instead of the hard setting. (I haven’t investigated the difference between the two.)

Free Codeweavers Wine today Only
This is for Mac or Linux. Their servers are VERY busy right now as you might imagine. But, if you’ve always wondered about crossover wine, see if you can get a copy today at Codeweavers main site. I was redirected to their DOWN page which is a lean page with the download links and a place to sign up for a license key. The license key you can register by the end of the month. Right now their server is crying since they’ve been dugg and slashdot’ted at the same time, but I’m sure it will be possible to slip in sometime today for a free copy of their polished product.
On a side note, I’ve been a paying crossover license owner for some time although on my current main laptop I’ve been using stock wine with VERY good results. If you look “up the food chain” though. Many of the good results we get in the free stock wine is thanks to the work at codeweavers. So…. in spite of todays free offer, they deserve the communities support if you believe that a working Windows compatibility layer is important to the future of operating systems such as Linux.
