I don't consider myself a Linux expert, I have enough knowledge to get by. I have had no problems setting up my Sheevaplug to do pretty much exactly as you describe your requirement. It uses twonkymedia to serve media from my USB HDD, it's got a webserver, and wTorrent (rTorrent with a web interface), and a few other tricks up it's sleeve. Running mine with the alpha6 installer, updated to the latest jaunty with apt-get dist-upgrade, and get the latest pre-built kernel from http://sheeva.with-linux.com/sheeva/If you have a little Linux knowledge, I say jump in, there are plenty of people on these forums, the general ubuntu support forums (although most scratch their head with ARM/embedded questions and don't quite get why you don't want full X-Windows with your apt-get...)

General Category / General Discussion / WARNING: Globalscale/Fedex European Import Duties.

If you are buying from Globalscale and getting it sent by Fedex to Europe. YOU WILL be stung for additional EU import duties. A nice letter will arrive 10 days or so after delivery...
My $99 plug has an addition cost of £15.91 (£9.11 VAT and £6.80 Fedex Admin fee).
I was hoping the dev kits would be classed as engineering samples, and thus VAT-exempt, but clearly not... Make sure you budget for this additional cost.. I think Globalscale should warn purchasers buying to EU that this will happen....

Saw similar things myself, the way the PCB is fitted and the hole for the miniUSB was not a great fit, and the plastic case was getting int the way of the miniusb connector, making a very crappy connection. A stong wind in the wrong connection would result in the thing disconnecting (bit of an exageration there perhaps...)
Make sure that lead is pushed all the way in and making a nice connection...

My Fedex "Priority" shipment spend 3 days sat in Memphis and then another 3 sat in Stanstead UK. Not very priority, even worse when I had to wait 8 weeks just to get the thing shipped.
If this were any other product, I would have told them to shove it where the sun don't shine. It's a testament to how good the product is, that people are prepared to wait for them (if begrudgingly)

General Category / General Discussion / Re: Backup and restore of the plug

I use this backup script (I run it monthly in my crontab) #!/bin/bash DIR=/usb/DataBackups/SheevaRootFS/$(date +%Y%m%d)/ mkdir $DIR dpkg -l |grep '^ii' > $DIR/InstalledPackages.txt tar cjf /$DIR/backup.tar.bz2 --exclude=/usb --exclude=/lost+found --exclude=/proc --exclude=/dev --exclude=/sys /
Created a tar/bzip of the filesystem into a directory on my USB drive, it creates a directory of todays date to create the file into. It also creates a text file containing details of what packages were installed when the snapshot was created. NOTE the fact I also exclude my mounted USB HDD, as I don't want a backup of the USB HDD on the USB HDD :-) Just save the script above as /etc/cron.monthly/backup.sh and give it execute permissions (chmod +x /etc/cron.monthly/backup.sh)

Another tip: I used the Alpha6 installer which came with a root filesystem, you can see what packages you have installed by using this command: dpkg -l |grep '^ii' (or if you want to send it to a text file: dpkg -l |grep '^ii' >installedstuff.txt I determined that I had x11-common installed, and I have no requirement for X11 on this box, so removed that, and all it's dependancies with the following command: apt-get remove x11-common ; apt-get autoremove ; apt-get clean This dropped by flash usage from 45% to 35% Nice...

What are you running? The plug has 512MB of DDR.
Lighttpd (PHP5) TwonkyMediaserver SSHD Screen (wtorrent/rTorrent session) I agree it's not alot, but I was under the impression that Linux would use up any available memory, as unused memory is wasted memory. However if a page page request comes in, it can't do anything with it..

Linux Stuff / General Linux questions / Swap file on HDD
|
on: August 13, 2009, 02:19:21 PM

Hi, I am getting regular occurances of the following in my DMESG: page allocation failure. order:3, mode:0x4020 Looking into this some more, it seems it occurs when my memory is exhausted. I suspect this is because I am not running a swap file/partition. I have created a 500MB swapfile on my USB HDD, and it seems to have stopped the errors, but having the page file on my HDD means it never spins down ! Is there another solution? I have been thinking of creating the swap file on SD card. Is this a safe thing to do? Will it prematurely damage the card?
