strange NFS problem
by Russell Coker 14 Feb '14

14 Feb '14

/data 10.1.2.3(rw,sync,no_subtree_check,no_root_squash) I have the above in /etc/exports, root on the NFS client can't run chown, it gets EINVAL. Both client and server are running Debian/Wheezy but the server has kernel 3.11 from Debian/Unstable (for BTRFS). I don't think it's a BTRFS issue as I have another BTRFS NFS server that works well. Any suggestions as to what I should investigate? Please include the "obvious" things as I probably missed something that's supposed to be obvious. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

capture and storage of marine AIS data
by Andrew Mather 11 Feb '14

11 Feb '14

Hi, I have recently added an AIS receiver to my gadget collection. The device was supplied by Marinetraffic.com and is configured to send the data it receives via the internet to populate the live chart you see on the web page there. There's a number of stations around the place, all of which contribute to the chart on a first-in best dressed basis for each position report. One of my areas of interest is VHF propagation and recently I noticed on my station's coverage graph that there had been some 'troppo' about and I had received signals from over 1000km away. Unfortunately, the Marinetraffic website only shows a sliding 2-day window of coverage and so I "lost" the chance to grab a screenshot before I realised. The device (a Comar SLR300N) also has a USB port through which data can be captured locally. I currently have this talking quite happily to OpenCPN on my Kubuntu machine and displaying the data received by my station, which I can compare against the live chart on the website. I'd like to be able to tap the USB output and grab the data as it comes off, parse it and store it locally so I can play around with it. I have found various bits and pieces, that do part of the job, but my attempts to glue it all together have been a bit Heath-Robinson. I believe the device sends NMEA sentences. I have verified this by using aisdispatcher and dumping the output and then using an online decoder/parser to view the data, but have not yet succeeded in setting it up to run a local routine without way more manual intervention than I want. Just wondering if anyone else has played with such devices and done a similar thing ?

Btw its Debian 7. The value 761 also seems like a weird number? Has anyone had any issue with Debian reporting wrong memory?

Hardware donation: IBM BladeCenter + 10 HS21/22 blades
by Avi Miller 10 Jan '14

10 Jan '14

Hey kids, I have an IBM BladeCenter chassis with 10 working (and 1 non-working) blades that is taking up space in my house. The chassis works great, and has both gigabit ethernet and fibre channel connectivity. The 10 working blades are mostly HS21s with dual-sockets and anywhere from 2GB - 8GB of memory (from memory). There is also an 11th blade I could never get to work, but could be used for parts, I guess. I’m happy to give the entire lot to anyone who’s willing to come pick it up from my house in Melbourne. :) Caveats: this thing is large. Like 5RU or 6RU or something. It’s also massively heavy. Fully loaded, it’s probably 60kgs+ or so. It requires 15A power (cables not included) and has four PSUs, so you need significant power supply (though it’ll run with only 2 connected). And finally, it’s stupendously loud. Like imaging an A380 landing about 10m away from you and then double it. This thing wouldn’t sit under someone’s desk. :) I’d prefer to give the whole lot away in one go, and I’d also prefer to give it to a non-profit or educational organisation, or anyone who is going to take hackvantage of it. I bought the whole lot for about $500 thinking I’d be able to do some virtualisation work with it, but the power requirements and noise just weren’t appropriate for a work-from-home environment. If this sound like something you’d like and you have a server room/basement/garden shed/bunker in which to store it, and some way of picking it up from an outer Northern suburb of Melbourne, please email me directly. NOTE: I can’t power the thing up any more, so please don’t ask specific questions about actual memory sizing or processors. I believe they’re Intel Xeon-esque processors. Each blade also has 2x internal HDDs. Essentially, you’re getting the lot for free, so think of it as a blade centre lucky dip! :) Email me off-list if you can take it off my hands. Cheers, Avi

Evolution Crashing
by david.zuccaro＠optusnet.com.au 09 Jan '14

09 Jan '14

Hi, Evolution is crashing on when it starts up. This is the error output: (evolution:24495): Gdk-WARNING **: The program 'evolution' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRequest (invalid request code or no such operation)'. (Details: serial 142 error_code 1 request_code 136 minor_code 19) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) I'm using debian and I recently upgraded to 7.3 (not sure if that has anything to do with this). Any ideas as to how I can fix this?
