### by SV for i2600k temperature
/sbin/modprobe coretemp
/sbin/modprobe pkgtemp

Now sensors report the temperatures.

I don’t say this is the best configuration possible but it’s the one that works INCLUDING pause and fast forwarding.

Relevant from the default are the custom header, extended protocol info and the mkv and avi lines.

Edit ./includes/Cache/Lite/Function.php, find the line reading

1

<strong>$arguments = func_get_args();</strong>

and replace with:

1
2
3
4
5

$arguments = func_get_args();
$numargs = func_num_args();
for($i=1; $i < $numargs; $i++){
$arguments[$i] = &$arguments[$i];
}

Check now, it should be working. Enjoy your new old site

After it boots press ALT+F2 to move to a console.

Let’s see first the layout:

1

lvdisplay

Let’s try and see if the volumes are there:

1

ls /dev/vgname/volume

On the first try I got nothing so we must enable them:

1
2

vgchange -a y
ls /dev/vgname/volume

Yep, they are all there.

Before anything else we need to check the volume for errors (resize2fs will not work if you don’t)

1

e2fsck -f /dev/vgname/volume

After that we resize the filesystem:

1

resize2fs /dev/vgname/volume 15G

Note that if you resize the volume to a size smaller than the file system it will trim it (the file system) and probably destroy it
Above, I reduced the filesystem from 453 to 15gb. That is a 438Gb gain.  Just to be on the safe side I will resize the volume only with 435Gb (leaving play room of over 3Gb which is plenty enough, 1Gb should be sufficient).

E.g. if you want your final size to be 15Gb than resize the fs to 14Gb, shrink the logical volume to 15Gb and then grow the file system back.

1

lvreduce -L -435G /dev/vgname/volume

Let’s put whatever was left for safety to use (grow back the file system to the full volume size):

1

resize2fs /dev/vgname/volume

Just to be on the safe side let’s check the filesystem for errors.

1

e2fsck -f /dev/vgname/volume

If you, like me, have resized the root than now you should reboot, otherwise simply mount back the volume and enjoy the free space by creating new volumes.

Remember! I resized a test environment, which didn’t matter if it went away. If you resize a production system (or anything else with useful data on it) remeber to BACKUP!

Please note that you’ll need to know the following:

• Windows username and password (the ones needed to access the share)
• The machine and share name. Something like //xpdesktop/pictures
• Have root access on the linux machine

Login on your linux machine as root. Type the following command to mount your remote windows share:

1
2

mkdir /mnt/share_name
mount -t cifs //xpdesktop/pictures -o username=john, password=johnspass /mnt/share_name

Where:

• xpdesktop is the network name of the Windows machine
• john is the username on  the windows machine
• johnspass is the password used to access the windows share
• /mnt/share_name is the target folder where the partition will be mounted (the folder you just created above)

You can now cd and ls the remote windows share as any other folder on the linux machine:

1
2

cd /mnt/share_name
ls  -l

I’ll show you in a following article how you can automatically mount a remote Windows share at boot time.

Get yours while it’s hot. And don’t forget to support the project by buying the dvd’s from the Slackware store.

Have fun!

Linux internet radio inside a vintage Blaupunkt radio case

When I first had the ideea I noticed an old ~ ’50s Blaupunkt Radio my father had in his basement. I investigated if the radio was worth restoring but the inside was rusted, the capacitors were long gone and most of the tubes were missing. It was more a case of rebuilding rather than restoring. I checked around the internet and saw that many models like this one existed, so it was not rare. And so, the radio was gutted and the insides went away. I cleaned and repaired the case as best as I could.

The first ideea was to have a big harddrive inside, an amp and external speakers hooked to it. It worked like this for a while until the motherboard I used fried and so did the amp. The project was eventualy put aside.

Anyways recently, I aquired an old Pentium III Compaq. By the case I could swear it was a small motherboard. It was NOT, and also the custom compaq psu had very short wires, but I managed to fit it inside. Since I have a media center pc hooked to the tv and the surround with all the music on it I decided to change the original ideea and make it what it originally was: a radio.

So, I gutted an old set of very good sounding Altec Lansing computer speakers and installed the small amp and speakers inside. I also mounted the motherboard and psu inside. One small fan on a side does the job of cooling everything down. I use one of the buttons on the front for the amp and another one for the computer.

I gave up the harddrive from the original design for a compact flash <-> ide adapter and the system now boots from a 4 Gb compact flash card. I think I could have squeezed everything on a smaller card but I decided to do all the compiling in place and since cards are cheap I went for a big one. The adapter has space for a second card and, if I want I can fit a second, bigger card, to hold some music.

I have a usb numpad for control and the usb lcd display featured some time ago on this site for display.

Software:

• mpd for playback
• mpc for mpd control
• Lcdproc and lcd-stuff for usb lcd display
• esekeyd for numpad control
• a bunch of bash scripts to glue everything in place

I hit a few problems:

• Event Music Player Client daemon does not work, at least with my keypad. So I had to use an external daemon – esekeyd with mpc to control mpd.
• lcd-stuff does not display the Name tag (that would be the radio station name, just the artist and track name. Fortunately it has a configuration tag to use as a title for the screen – on every playlist change a bashscript modifies that configuration setting to reflect the radio station’s name and reloads lcd-stuff – it’s ugly but it works.
• I didn’t find a way to save .pls and .m3u files and have them recognized by the mpd database. So a script is called at boot time (and also can be started from one of the keys on the keypad) to generate a playlist of the radio stations. Control is easy after that, it’s a matter of play/stop, next / prev
• I wanted to have a way to shut down the system safely from the keypad. OTOH I didn’t want shutting down every time I hit the wrong key. But esekeyd doesn’t support combinations. So I had * create a file, / create a second one but only if the first file (created by *) existed and on backspace press verify if the two files exist and if yes poweroff.

I’ll post soon more photos, the insides and the configuration files and bash scripts used.

2011 Update

It never functioned reliably and so I decided on rebuilding it once more

• The Compaq Deskpro EN was reassembled and donated to charity.
• I bought the cheapest intel motherboard with an atom processor.
• With the motherboard I also bought a small, slim PSU which happened to have the loudest annoying fan I ever heard. Fortunately the motherboard and disk use small amounts of power so no heat is produced. I hooked the fan to 5v and now it’s quiet.
• I got a good deal on a pair of Microlab powered speakers (were the last in stock, open box) so I hooked those up to the radio. It’s still possible to use the insternal speakers but why would you want to
• Used a 500Gb sata disk that I also had around.
• Took the oportunity to update slackware, mpd and everything else to the latest versions.
• Took out the LCD until I can find time to build it in a nice case
• The usb numpad is still there but I’m having trouble finding a daemon that actually works between two reboots
• I use Client175 for web control and also Sonata on n800 and DroidMPD on my wife’s tablet to control it. Having 500Gb it’s got it’s music back (not only internet radio).
• Since playlist support seems to be better now I have each radio stored in a playlist that DroidMPD or Client175 can simply load.
• The best thing is that there are no custom hackish scripts left that could break all the time. It’s just stock mpd, playlists and the clients. Oh, I also have the command line clients installed for when I ssh into it using my n900.
• The only problematic thing left is the shitty usb wi-fi adapter I use (don’t know, might be the drivers) it’s slow and sometimes connection drops. I added ping -c1 GATEWAY_IP in cron every 2 minutes and this seems to help.

Somebody in the comments asked for the configurations and scripts  The original ones, from the compact flash should still be in backups somewhere but I don’t see how they could help, as they point to old or discontinued versions.  (lcd-stuff comes to mind). The configuration I use now is as stock as one can get with mpd. Let me know if you have questions about it and also please recommend me a daemon that can listen for keystrokes from the usb keypad and it’s stable.

Have fun.

I have a linux Jukebox !

One of the problems I faced is needing to make changes on inherited machines that nobody knew the passwords for. So, if you face the same problem, or you simply forgot the root password because you usually use a normal user account here’s what you have to do to reset the password.

What you need: a bootable linux cd or flash usb drive. (You could use the slackware install disk, but any bootable, or Live CD should do as long as it has drivers for your filesystem and basic hardware)

You need to reboot the machine and boot it of the CD/USB stick. For the sake of the demonstration I will asume you use the slackware 12.2 install disk. If you use another just boot it and open a shell/console.

Log in as root.

Create a temporary directory to mount your / (root) partition where Slackware Linux is installed:

1

mkdir /tmppart

Mount your partition there:

1

mount /dev/hda1 /tmppart

Of course you need to replace hda1 with the partition where / is on your drive. Next you need to edit /etc/shadow to remove the root password.

1

vi /tmppart/etc/shadow

Locate the line starting with root: followed by letters and numbers. It’s easy, it’s usually the first line in the file. Remove everything between the first two : . Alternatively, if you know the password of another user copy everything from between the first two : to the root user.  Save the file and reboot.

Root should now have no password / a password identical with the one of the user you copied it from.

Easy. Useless to say that you must understand that if you don’t own the system / don’t have express permission from the owner you are doing something illegal. If you get arrested/fired it’s your problem.
