Love and hate with Asterisk

2008-08-07T13:58:25+00:00

Since about 1 year, I'm using asterisk in production for a Call Center with 54 SIP phones. All the computers ( workstations and servers ) are running Mandriva Linux. Except my NFS issues, the only issue I have in this call center is ... Asterisk :(

Indeed many times I experienced regressions with Asterisk. At first it was ChanSpy which was broken ... Now it's MixMonitor which is recording too fast ( bug #42566 ). In others words, since about 1 week, all our recordings are somewhat useless. This is really annoying to see so big regressions in a stable release for a software supposed to be used in critical missions. I do hope that this bug will be fixed shortly. However I will have to find a way, in the future, to be able to revert back to a previous version, or to test the main features before updating to a new version.

Now people will ask why am I using Cooker for my Asterisk server ? It's because I need to use the latest versions in order to have ChanSpy fixed, and presently there's no backport version of asterisk.

Duyvendak

2008-08-06T21:39:04+00:00

Omdat niemand anders in de groenlinkse blogosfeer het aan de orde gesteld heeft, doe ik het maar even: de bekentenis van Wijnand Duyvendak betreffende een inbraak bij het ministerie van EZ in 1985.

Ik ken de feiten en omstandigheden niet goed genoeg om daar direct een oordeel over klaar te hebben. Soms kan burgerlijke ongehoorzaamheid noodzakelijk zijn om een verandering ten goede te bewerkstelligen. Moet je je 23 jaar na dato hier nog over opwinden? Aan de andere kant is inbraak bij de overheid natuurlijk een serieus misdrijf.

Los daarvan doet hij prima werk als Kamerlid. Maar wat ik me echt afvraag, is of Duyvendak de diverse kandidatencommissies hierover heeft ingelicht voordat hij in de Kamer terechtkwam. Met de affaire Pormes in het achterhoofd zou je anders toch haast gaan denken dat dit Wijnands manier is om de politiek gedag te zeggen.

Update: de kandidatencommissie was dus op de hoogte. Zie ook de bijdragen van Paul, Arnoud en Selçuk. Blijft voor mij staan de vraag of het Congres (en daarmee de kiezer) niet op de hoogte had moeten zijn toen de kandidatenlijsten werden vastgesteld. Dan hadden de leden hun eigen afweging kunnen maken wat betreft het actieverleden van de betreffende kandidaat in plaats van daar achteraf mee geconfronteerd te worden.

Voor wie er geen genoeg van kan krijgen: Sargasso’s Duyvendak-poll en de discussie op het GroenLinks Forum.

Open letter to the developers of TrueCrypt

2008-08-06T18:33:21+00:00

Dear TrueCrypt Developers

I hate you all. You’re a bunch of asshats.

Apparently, the good name of TrueCrypt is so incredibly valuable that you can’t possibly permit anyone to redistribute it with the tiniest of modifications under the same name.

The minor problem with that is that it completely fucks things up for distributions. We really can’t package just about anything without modifying it. For TrueCrypt that involves a small patch to fix your ridiculous system of having your users provide the source tarball for wxgtk and building an internal copy of it; the patch simply lets us build against the system wxgtk, as nature intended. It also involves, y’know, *putting it in a package* (which is a modification under your license), adding a menu entry and consolehelper stuff to let normal users run it - you know, all the simple stuff that people actually want.

So the TrueCrypt package we want to ship with Mandriva has been ‘modified’. And according to your ridiculous license, that means we can’t call it TrueCrypt. It can’t identify itself as TrueCrypt anywhere. It can’t use any of the original graphics you ship it with, and it has to include some specific bits of boilerplate text and specifically *exclude* some others.

This is bad enough. Yet you can’t even make it easy for us, can you?

If you’re going to require anyone who modifies your application in the tiniest of ways to rename it, you could at least MAKE IT EASY TO RENAME. Y’know, have the name be a variable defined once in one file; then we could simply change that and we’d be done. But no. The name is hardcoded in several dozen places and there are *several* variables in which it crops up. All of which needs to be changed. We can’t even just do s/truecrypt/somethingelse/ on the entire source tree because that would change it in some places where the license specifies it *shouldn’t* be changed. VERY FUCKING GOOD, THANK YOU.

If you’re going to require certain boilerplates be changed when the package is ‘modified’, at least make this easy. It could perfectly simply just be a build switch. But no, I have to go into random source files where the original boilerplate is hardcoded, and change it by hand. Awesome. Thank you once more.

And finally, if you’re going to require that no original graphics be used, you could at least MAKE THE FUCKING THING BUILD WITHOUT THE GRAPHICS FILES. It’s not like they’re vital to functionality; it could just display a blank grey space or whatever. No functionality would be lost. But no, if I just remove the files, the build breaks. So I have to manually replace every single bleeding graphic with a stupid GIMPed up replacement. Awesome.

So in summary your ridiculous license wasted eight hours of my life and results in a much uglier and more modified package than would be necessary if you didn’t have such insane terms in the first place. Way to shoot yourselves in the foot, guys.

Anyway, who the hell thought such a stupid license was necessary? Why are you so special? Imagine what the Linux world would be like if everyone decided to act like you? We’d be releasing Mandriva Pinux, featuring JDE 4.1, DWARF 2.24 and AjarOffice 3.0. Actually, we wouldn’t, because we’d have wasted all our time on stupid rebranding patches and wouldn’t be able to ship anything. Everyone else seems perfectly happy to release their code under a license which lets distributors *distribute* it (this is after all our job). Get over yourselves and join them. Or hadn’t you ever wondered why major distros don’t ship your software?

For anyone actually wanting to use TrueCrypt on Mandriva - the package is called realcrypt. 6.0a will be in /backports for 2008 Spring and 2008 soon, hopefully. It’s in Cooker now.

Fondation adapté au cinéma

2008-08-06T18:13:05+00:00

L'une des plus grande oeuvre de science-fiction qui ait existé sera surement adapté au cinéma : Fondation ( ou plutôt le Cycle de Fondation ).. C'est tout simplement génial. Il y a eut Dune ( Herbert ), Le seigneur des anneaux ( Tolkien ), et maintenant Fondation ( Asimov ). Wow, pour moi ces oeuvres constituent des références dans leur domaine ( S-F, Fantastique ).
Bon pour ma part, je vais me replonger dans la lecture du cycle des Robots et de Fondation :) Je vais aussi voir pour découvrir cantos D'Hypérion par Dan Simmons.

Faking filesystem access

2008-08-06T13:43:18+00:00

The traditional method of dealing with filesystem images is to mount them as loopback devices, and that is a simple, elegant and universal way to change its contents in any way you feel fit. It has the disadvantage, however, of requiring superuser privileges — which you may not have in every host you frequent, or you wisely don’t wish to grant to anyone using your machine to develop filesystem images. Christian Hohnstädt’s e2fsimage solves the problem allowing one to copy an entire subtree into a image file, but what if you want to extract, examine or manipulate arbitrary content?

Word press plugin: blogger.com publisher released

2008-08-04T23:41:16+00:00

I wrote over the last couple of days, a word press plugin to publish items to blogger.com. I’ve release this now, version 0.1, available at http://www.linuxsolutions.co.nz/gdatablogger/

It’s still 0.1 because

No validation of inputs in admin menu
No error handling
No nice GUI to pick tags and categories

But, it now actually does everything I want it to do, so I’ve scratched my itch, and will only build these features if I get feedback from the community that they want them., or I find myself with spare time.

Testing admin for wp plugin

2008-08-04T23:39:33+00:00

Just building the admin section for my word press plugin. It loads and stores values in the word press options tables.

Only thing left to do is to make it GPL, and make the tag/category selection nicer.

Hauppauge WinTV-HVR900 on Mandriva Linux 2008.1

2008-08-04T23:31:00+00:00

On the second attempt to get my HVR900 working with Mandriva 2008.1, I’ve had success, and can now watch Freeview HD*, terrestrial on my laptop.

I have had success after some help from Steven Ellis, who knows a lot about these things, and has done a lot of the hard work of getting Freeview HD, for Linux in NZ working. The steps for Mandriva 2008.1 is actually a lot easier than the instructions for Ubuntu, as it didn’t require anything very fancy to be done with the kernel, I was able to compile the HVR900 drivers (em28xx-new) against the Mandriva laptop kernel, after downloading kernel-source-2.6.24.5-2mnb-1-1mnb1 rpm and creating a symlink in /lib/modules/2.6.24.5-laptop-2mnb to the source.

The only tricky bit was extracting the correct firmware, which required me to install a different kernel source, purely to get a perl script out of it, as it was not in the default Mandriva kernel source, although will be in future versions by the looks of things.

Steps taken

Install latest tmb source: urpmi kernel-tmb-source-latest-2.6.24.7-4mdv2008.1. This includes /usr/src/2.6.24.7-tmb-4mdv/Documentation/video4linux/extract_xc3028.pl which is needed.
Extract the firmware, following instructions from: http://www.linuxtv.org/wiki/index.php/Xceive_XC3028/XC2028
1. wget http://www.steventoth.net/linux/xc5000/HVR-12×0-14×0-17×0_1_25_25271_WHQL.zip
2. unzip -j HVR-12×0-14×0-17×0_1_25_25271_WHQL.zip Driver85/hcw85bda.sys
3. perl /usr/src/2.6.24.7-tmb-4mdv/Documentation/video4linux/extract_xc3028.pl
4. cp xc3028-v27.fw /lib/firmware
Download kernel source: urpmi kernel-source-latest-2.6.24.5-2mnb1
Create a link: /lib/modules/2.6.24.5-laptop-2mnb/source -> /usr/src/linux-2.6.24.5-2mnb/
Download driver source: hg clone http://mcentral.de/hg/~mrec/em28xx-new (urpmi mercurial first)
Compile with ./build.sh in em28xx-new. Add yourself to the video group.
Download and compile mplayer svn: (http://www.mythtv.co.nz/mythtv/digital-tv/dtt-debugging/ step 1). I recommend installing it in /usr/local/bin, so you can continue to use your normal mplayer.
download NZ channels file - see step two from above link.
find good reception = watch TV.
add some nice icons to launch mplayer.

The mplayer command I use to play tv is:

/usr/local/bin/mplayer -lavdopts fast:threads=2 -vf pp=fd -mc 2 -framedrop  -fs dvb://"TV ONE"

Screenshots.. (showing off!)

TV one, paused for screenshot

TV one, with compiz desktop rotation

Startup Icons

Notes

1080i still does not work well, sometimes not opening at all before mplayer crashes, sometimes opening and playing for a few seconds before crashing or looking bad. I am hoping that if I stick with mplayer svn, soon this issue will be fixed.

Recording with mplayer is quite easy.. I use the following command.

/usr/local/bin/mplayer -dumpstream -dumpfile tv1.ts dvb://"TV ONE"

Threading

I’ve noticed that even when I tell mplayer to use threads, I seem to only get load on 1 CPU at a time, it keeps jumping between cpu’s, but never do I get both CPU’s at 100%, only about 50%. I think maybe mplayer is not running on multiple threads, even with the -lavdopts fast:threads=2 option. I’ve tried -lavdopts fast:threads=4 and it seems a little better, but still does not really use both cpu’s 100%

Depressive smorgasboard

2008-08-03T23:25:56+00:00

Strange things you do amidst a depressive crisis when you brain doesn’t act quite the way it should act under normal circumstances.

You write code quickly and obsessively. (In a few days I started to write two small utilities, one to manipulate partitions in a hard disk image and other that allows userspace access to filesystem images without loop-mouting them. These can be useful for some in-house projects, so this forced recovery gave me the much sought-after time to implement them.)

Following a news reporter in Istanbul

2008-08-03T14:46:50+00:00

Last friday, I saw an interesting program called NieuwsLLiNK on Dutch public television about life and work of news reporters in foreign countries. This edition was about Turkey. A Dutch news anchorman, Roelof Hemmen, visited the offices of the Turkish station ATV. It was recorded right at the time I was in Istanbul myself for the GUADEC conference so the Bosphorus shots look very familiar :). Altough the voice-over is in Dutch, I think it’s still interesting for non-Dutch viewers as well:

English signs in China

2008-08-03T11:06:18+00:00

Related to the very funny Translate server error sign, Funda posted another link pointing some very bad translations.

The expensive sun multiples by a duty a police to buy a brigade could be a small poem but it actually tells where is the police office of Guiyang station.

This other website gives a more detailed explanation for this one:

It's basically a character-by-character translation of 贵阳乘警支队: The expensive (贵) sun (阳) multiplies (乘) by a duty (??) a police (警) to pay (支) a brigade (队). What it should be: Guiyang (贵阳) Rail Police (乘警) Detachment (支队).

Even google would do better: Guiyang marshals detachment.

But at least there are the words "police" and "brigade" so someone looking for the police would find it :)

IKEA

2008-08-03T10:24:02+00:00

In my Living room I currently have 3 BESTÅ bookcases, and wanted to buy an additional one as they are now full.

I was very disappointed to see that IKEA France now only has the 40cm deep ones while mine are 20cm (perfect for pocket books, DVD and CD).

I could find it on their Australian website for 99 AUD which according to google is the same price I paid for mine 3 years ago, but Australia is a bit far from France, and Belgium or Switzerland don't have it. Japan and China also have it...

Should I move to Australia, China or Japan or buy a different one that would not fit ?

Wordpress replication plugin

2008-08-01T22:51:46+00:00

I have been creating a plugin for word press, that can publish certain posts to eblogger, using the gdata api. It now supports setting the published date, title, and content, formatted in HTML.

I’ve been quite pleased with it, and will be releasing it under GPL, fairly soon. I just need to build the page for changing it’s settings, which is quite simple, as it only needs the users username, password and blog id, plus a list of the categories and tags to publish.

A future feature, could loop over old posts and post them also, if they meet the criteria, but I don’t really feel it’s worth spending much time on yet.

Oh, and some of the times on older posts will be wrong, Had to setup a timezone offset, so that it got it right.

Creating a wordpress plugin

2008-08-01T22:50:14+00:00

I am just starting to create a new word press plugin that publishes posts to eblogger using the gdata api.

It’s quite easy so far, and I have to say, word press is pretty nice to develop with..

And I’ve just implemented updates, as well as posting new posts.

how rpm delta's should work

2008-08-01T22:41:01+00:00

Server consists of: rsync, cpio. - it should only have copies of the latest rpms on it. It does not need the other ones to create diffs, as that is done on the client. When server gets a request, it extracts the rpm, if not already extracted, into a temporary store. Then sets up an rsync server for the client. It also has a file with the md5sum’s of all the files, the pre and post scripts, and rpm info.

Client:

compares rpm file database of md5sums against copy on server.
copies files that are different into tempory spot
rsyncs the modified files from the server to the client.
gets the new pre and post scripts, updated md5sum list and info
builds itself a new rpm based on the contents of the old one, plus the changed files.
uninstalls the old rpm and installs the new one.

This should save significant bandwidth, be easy to implement, and use existing technology.

From Mandriva 2008.1 (cooker), on EEE pc

2008-08-01T22:36:48+00:00

Yup, installed Mandriva 2008.1 cooker (rc nearly 2) on my eee pc, and it mostly works, although I do have a few emails to send to cooker about problems, like the default selection of packages on CD1 for i586.

Compiz works ok, yet to find out how to allow windows to be moved upwards, as they tend to be too big for the screen.

mdadm buggy

2008-08-01T22:36:29+00:00

Well, just had a rather nasty experience.

After rebooting my computer, because I put a new fan in it, as it started up, I saw it fail to start /dev/md4 and /dev/md5 raid0 devices. This then resulted in not being able to start any volumes within my other volume group. Nasty!. So, of course /storage could not be mounted.

So, TO WORK…

After some careful investigation, /proc/mdstat showed that /dev/md4 only had once device, (hda8), and not hdb8. It showed md4 as inactive.
and dmesg shows:

md: array md4 already has disks!
md: array md5 already has disks!

Very strange. Becuase it show have shown sometime like this:

md4: setting max_sectors to 128, segment boundary to 32767
raid0: looking at hda8
raid0: comparing hda8(49150720) with hda8(49150720)
raid0: END
raid0: ==> UNIQUE
raid0: 1 zones
raid0: looking at hdb8
raid0: comparing hdb8(49150720) with hda8(49150720)
raid0: EQUAL
raid0: FINAL 1 zones
raid0: done.
raid0 : md_size is 98301440 blocks.
raid0 : conf->hash_spacing is 98301440 blocks.
raid0 : nb_zone is 1.
raid0 : Allocating 8 bytes for hash.

lvs showed that it could not find all the physical volumes to start the “other” volume group.

So, I stopped the device:
mdadm -S /dev/md4
Then reassembled it, using:
mdadm -A /dev/md4 /dev/hda8 /dev/hdb8

This then started fine, and showed it as clean.

So, an
lvchange -a /dev/other/storage
had me back in business.

How to break things in interesting ways

2008-08-01T22:35:52+00:00

Well, over the last 15 hours or so, I’ve broken stuff twice, inside of a VM thankfully.

I’ve been trying to do some testing to ensure that the pvmove command is going to work ok on my main system, so thought I would test this first within a vm. First test went just fine. Thought I’d test another pvmove as well, so did, and while I was doing that, decided to put a little disk load on the system by copying the /lib/modules/kernel files. All was going sweet.. So I decided to remove that files again, however, being inside a vm, it has the occasional issue with keyboard repeat, or something, anyway, long story short, ran rm -rf / mytestkernel modules. See the mistake! an extra space. It killed the system pretty quick.. oh, and pvmove fails if you trash /dev and /proc while it’s running… not really surprising!

So, lucky it was a VM.. unlucky, I didn’t have a snapshot. So, in the morning rebuilt a new vm, ready to try the test again.. Now, on my new vm, updated it, and created an LVM with a raid1 disk. Then added a raid0 device and rebooted. Ouch… did not reboot. I got an interesting message tho: “lvm locking type 1 failed”. After much playing, booted from a rescue cd and tried to mount up the filesystems.

Anyone booting from a rescue cd should know the drill: bring up the raid, using mdadm –assemble –scan if needed, modprobe dm-mod dm-mirror dm-zero, vgs, vgchange -a . mount /dev/system/root /mnt/root

chroot /mnt/root

now, an interesting problem I had, but found the solution to is: how to run mkinitrd from inside a chroot. Every time I’ve tried it, I would mount /prod, run it. it would use 100% cpu and go very slow. I found out why. you need to mount /sys within the chroot also. this can be done using mount -t sysfs /sys /sys

then mkinitrd will run. however, I am getting ahead of myself. The problem, I discovered was that the raid0 module was not in my initrd, so when I booted, my raid0 device would not come up, which resulted in lvm not having all it’s physical volumes, so it would not start, so it could not operate properly.

The solution I used before finding this out was to just remove my raid one device which did not have any extents allocated to it from the volume group.. When I did this, the system booted fine.

So, end story was to run mkinitrd on the system after starting a raid0 device. This works because mkinitrd looks at the modules loaded in the running kernel and included them if it finds they are needed.

oh. and have now made a snapshot, so can go break some more stuff!

script / record / replay

2008-08-01T22:21:11+00:00

record a session to a file.. use script.

creates a typescript file that can be played back. App available to play them back, compiled from RPM util-linux

SCRIPT(1)                 BSD General Commands Manual                SCRIPT(1)

NAME
     script - make typescript of terminal session

SYNOPSIS
     script [-a] [-f] [-q] [-t] [file]

DESCRIPTION
     Script makes a typescript of everything printed on your terminal.  It is
     useful for students who need a hardcopy record of an interactive session
     as proof of an assignment, as the typescript file can be printed out
     later with lpr(1).

     If the argument file is given, script saves all dialogue in file.  If no
     file name is given, the typescript is saved in the file typescript.

     Options:

     -a    Append the output to file or typescript, retaining the prior con-
             tents.

     -f     Flush output after each write. This is nice for telecooperation:
             One person does `mkfifo foo; script -f foo' and another can
             supervise real-time what is being done using `cat foo'.

     -q     Be quiet.

     -t     Output timeing data to standard error. This data contains two
             fields, separated by a space. The first field indicates how much
             time elapsed since the previous output. The second field indi-
             cates how many characters were output this time. This information
             can be used to replay typescripts with realistic typing and out-
             put delays.

     The script ends when the forked shell exits (a control-D to exit the
     Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
     set) for the C-shell, csh(1)).

     Certain interactive commands, such as vi(1), create garbage in the type-
     script file.  Script works best with commands that do not manipulate the
     screen, the results are meant to emulate a hardcopy terminal.

Playback of script files

REPLAY(1)             User Contributed Perl Documentation            REPLAY(1)

NAME
       replay - play back typescripts, using timing information

SYNOPSIS
       replay timingfile [typescript [divisor]]

DESCRIPTION
       This program replays a typescript, using timing information to ensure
       that output happens at the same speed as it originally appeared when
       the script was recorded. It is only guaranteed to work properly if run
       on the same terminal the script was recorded on.

       The timings information is what script outputs to standard error if it
       is run with the -t parameter.

       By default, the typescript to display is assumed to be named "type-
       script", but other filenames may be specified, as the second parameter.

       If the third parameter exits, it is used as a time divisor. For exam-
       ple, specifying a divisor of 2 makes the script be replayed twice as
       fast.

EXAMPLE
        % script -t 2> timingfile
        Script started, file is typescript
        % ls
        
        % exit
        Script done, file is typescript
        % replay timingfile

Howto configure a 3M mouse with scrolling in Linux

2008-08-01T22:03:31+00:00

Add this to your xorg.conf file.

Section "InputDevice"
# Configuration for 3M mouse, with scrolling
    Identifier "Mouse2"
    Driver "mouse"
    Option "Device" "/dev/input/mouse2"
    Option "EmulateWheel"        "on"
    Option "EmulateWheelButton"  "2"
    Option "EmulateWheelInertia" "20"
    Option "YAxisMapping"        "4 5"
    Option "XAxisMapping"        "6 7"
    Option "EmulateWheelTimeout" "150"
EndSection

Note, make sure other mouse section refers to your other mouse, not the general mouse. This can be tested by doing cat /dev/input/mouse1, mouse2, etc and moving a mouse, to see which mouse is which.

splitting a volume group

2008-08-01T22:00:59+00:00

I just split a logical volume into two volumes.

I did this by using pvmove to move data around inside the volume group after adding more disks.
This left me with just 1 logical volume on a set of five physical volumes that I wanted to spit off from the others.

Note: I set physical volumes to non allocatable when using pvmove so that it moved them to the right place.

So, before I split, pvs looked something like this

PV         VG     Fmt  Attr PSize   PFree
/dev/md1   system lvm2 a-    44.92G   8.32G
/dev/md2   data   lvm2 --    93.75G  93.75G
/dev/md3   data   lvm2 --    93.75G  93.75G
/dev/md4   data   lvm2 --    93.75G  93.75G
/dev/md5   data   lvm2 --    93.75G  11.73G
/dev/md6   data   lvm2 a-    92.62G      0
/dev/md7   data   lvm2 a-   306.41G 212.67G
/dev/md8   data   lvm2 a-   306.41G 212.67G
/dev/md9   data   lvm2 a-   318.68G 213.21G

Then, I ran
vgchange -a n data
vgsplit -v data other /dev/md2 /dev/md3 /dev/md4 /dev/md5 /dev/md6
vgchange -a y data
vgchange -a y other

pvs then looked like

  PV         VG     Fmt  Attr PSize   PFree
  /dev/md1   system lvm2 a-    44.92G   8.32G
  /dev/md2   other  lvm2 --    93.75G  93.75G
  /dev/md3   other  lvm2 --    93.75G  93.75G
  /dev/md4   other  lvm2 --    93.75G  93.75G
  /dev/md5   other  lvm2 --    93.75G  11.73G
  /dev/md6   other  lvm2 a-    92.62G      0
  /dev/md7   data   lvm2 a-   306.41G 212.67G
  /dev/md8   data   lvm2 a-   306.41G 212.67G
  /dev/md9   data   lvm2 a-   318.68G 213.21G

Kicker Icons in Mandriva

2008-08-01T22:00:27+00:00

If your like me, and run kicker, in Mandriva, you might have noticed that the icons in kicker don’t look so sharp. This seems to be because kicker always uses the 32 pixel icons, even if you have kicker at a size larger than 32 pixels. I’ve found a way to fool it into using larger ones.

Create a directory, ~/.kde/share/icons/crystalsvg/32×32/apps/ then copy in nicer, 64×64 or 128×128 icons from your /usr/share/icons/ directory. (use find in konqueror to find them)

Indeed. I'll bite the bullet and go for the 2 step jump!

Done three 2007.0 -> 2007.1's so far.

It all went smoothly. I followed my usual procedure which is roughly:

   1. Find any .rpmnew files and resolve them prior to upgrade.
   2. Copy /etc/ to a safe location for sanity (probably never used)
   3. rpm -qa --nosignature | sort >
/home/rpms/upgrades/rpmlist.2007.0.$(hostname -s).txt
   4. urpmi.removemedia -a
   5. urpmi.addmedia Main-32
/home/rpms/Mandrake/2007.1/i586/media/main/release
   6. urpmi.addmedia --update MainUpdates-32
/home/rpms/Mandrake/2007.1/i586/media/main/updates
   7. urpmi.addmedia Contrib-32
ftp://anorien.csc.warwick.ac.uk/Mandriva/official/2007.1/i586/media/contrib/release
   8. urpmi.addmedia --update ContribUpdates-32
ftp://anorien.csc.warwick.ac.uk/Mandriva/official/2007.1/i586/media/contrib/updates
   9. urpmi --auto --no-verify-rpm urpmi 2>&1 | tee -a
/home/rpms/upgrades/urpmi.2007.0.$(hostname -s).log
          * This appears to remove your /etc/localtime (leaves an
.rpmsave meaning the machine is now in UTC mode)
  10. urpmi --auto --no-verify-rpm --auto-select 2>&1 | tee -a
/home/rpms/upgrades/urpmi.2007.0.$(hostname -s).log
  11. Do the kernel
  12. Switch to grub
  13. Reboot
  14. rpm -qa --nosignature | sort >
/home/rpms/upgrades/rpmlist.2007.1.$(hostname -s).txt
  15. Compare the packages and remove orphaned libs still installed.

There are quite a few 2007.0 packages that are still part of 2007.1. The
last step would be made a lot simpler if all packages were rebuilt with
the relevent dist suffix for each release - despite the PITA that is to
do in terms of all the bump+submits required.

During step 9 on my first u/g my /etc/localtime was removed, I replaced
it with a symlink but when timezone updated it moaned that I'd created a
symlink.... with the second u/g it was replaced automatically, so the
answer is - don't touch it ;)

Other than that everything went pretty smoothly.

Changing storage under lvm

2008-08-01T21:56:21+00:00

I’ve got an lvm volume group that I want to changing from using raid0, to using raid1.

The volume group is made up for a few raid0 volumes. To change the storage, I do the following:

pvmove the data off at least one of the physical volumes.

[root@wizards nelg]# pvs
  PV         VG     Fmt  Attr PSize   PFree
  /dev/md1   system lvm2 a-    44.92G   8.32G

  /dev/md3   other  lvm2 --    93.75G  93.75G
  /dev/md4   other  lvm2 --    93.75G  93.75G
  /dev/md5   other  lvm2 a-    93.75G   1.73G
  /dev/md6   other  lvm2 a-    92.62G      0
  /dev/md7   data   lvm2 a-   306.41G  52.67G
  /dev/md8   data   lvm2 a-   306.41G  62.67G
  /dev/md9   data   lvm2 a-   318.68G 133.21G
[root@wizards nelg]#

vgreduce the volume,

then remove it:

lvm> vgreduce other /dev/md3
  Removed "/dev/md3" from volume group "other"
lvm> pvremove /dev/md3
  Labels on physical volume "/dev/md3" successfully wiped
lvm> pvs

The device looks like this currently in mdadm

Stop the device

[root@wizards nelg]# mdadm -S /dev/md3
mdadm: stopped /dev/md3

This means the pvs shows:

[root@wizards nelg]# pvs

  /dev/md9   data   lvm2 a-   318.68G 133.21G

Now, all that is remaining is to change the device, update /dev/mdadm.conf and rebuild initrd to reflect the change.

So. Double check that devices are not in a current array:

grep hda7 /proc/mdstat
grep hdb7 /proc/mdstat

Build the new device

mdadm --create /dev/md3 -l 1 -n 2 /dev/hda7 /dev/hdb7

This will warn, as per below

[root@wizards nelg]# mdadm --create /dev/md3 -l 1 -n 2 /dev/hda7 /dev/hdb7
mdadm: /dev/hda7 appears to be part of a raid array:
    level=raid0 devices=2 ctime=Sun Jan  8 23:02:59 2006
mdadm: /dev/hdb7 appears to be part of a raid array:
    level=raid0 devices=2 ctime=Sun Jan  8 23:02:59 2006
Continue creating array?  y
mdadm: array /dev/md3 started.

This now has a new device, as per below.

[root@wizards nelg]# mdadm -D /dev/md3
/dev/md3:

[root@wizards nelg]#

Notice that the devices are being synced.

/proc/mdstat shows:

md3 : active raid1 hdb7[1] hda7[0]
      49150720 blocks [2/2] [UU]
      [==>..................]  resync = 13.3% (6540864/49150720) finish=23.3min speed=30358K/sec

Now, I take the UUID: 60f87451:d385361e:c4cdb003:fcc220ea and update /etc/mdadm.conf to reflect this.

I.e.

-ARRAY /dev/md3 UUID=2b3493e2:0a59d252:d9ed1514:2cb69c87 auto=yes
+ARRAY /dev/md3 UUID=60f87451:d385361e:c4cdb003:fcc220ea auto=yes

Next is to update initrd.

The is two choices. Build a new initrd, or just change this one.

As I like to be able to boot my system, I’ll do both, so I have a spare if one does not work.

Approach 1

[root@wizards boot]# mkdir tt2
[root@wizards boot]# cd tt2
[root@wizards tt2]# cat ../initrd-2.6.24.5-server-2mnb.img | gzip -d -c | cpio -i
12546 blocks
[root@wizards tt2] ls etc
blkid/  ld.so.cache  ld.so.conf  ld.so.conf.d/  lvm/  mdadm.conf  suspend.conf
[root@wizards tt2]# pwd
/boot/tt2

So, as you can see, the is an mdadm.conf in the initrd file.

cp /etc/mdadm.conf /boot/tt2/etc/

the, put the initrd back together.

find . | cpio -H newc --quiet -o | gzip -9 > ../initrd-2.6.24.5-server-2mnb-new.img

Note, I made this a new name, as I don’t like to overwrite my existing initrd, just in case. So, I’ll just change my symlink to use this one.

Approach 2

 mkinitrd /boot/initrd-2.6.24.5-server-2mnb-new1.img $(uname -r)

Both approaches should work. I’ll comment further if one does not.

Now, last but not least, is to make use of our new device.

In my case, create a new volume group for my virtual machines, after adding this device to lvm.

lvm> pvcreate /dev/md3

ghc people have been using darcs for more than 2 years and are now evaluating switching to another DVCS. The wiki page is interesting, comparing workflow and performances.

They also have some interesting fact about community size: #git: 388 members, #bzr: 143 members, #mercurial: 118 members, #darcs: 39 members. And also a picture from Debian.

KDE 4.1 again

2008-07-30T13:11:22+00:00

I had a look at a review on linux.com called "KDE 4.1 rocks the desktop" and was expecting to find some description of interesting things that have been added. Instead, the article is quite empty but worse, it contains only one screenshot which make dolphin (the file manager) look unusable (I don't know if it is, if this is the default layout, etc but think kind of article and screenshot will not motivate me to sped time trying). So, here is dolphin:

So, the useful part, the one with the name of your files (yes this is a file manager, I usually look for my files in file managers, using their name), is 77px out of the 614px of the window, that's 12% of the space used for the main content. Then you have a wide column with the size, and then a column with written 2008. Yes you'll get the full date if you scroll but I hate having to scroll to be able to get the useful information, just because the available space is wasted.

Why not having both side panels on the same side ? why not reducing the size column ?

Maybe this is not the default layout but that's sad that an article which is supposed to advertise a great release of KDE just make me feel it's even worse than KDE 3.

I was looking at a screenshot of KDE 4.1 which was released today, and noticed 2 things, one bad and one nice.

The bad one, the font rendering looks very bad (spacing between letters is often wrong, see "Favorites" for example). KDE is probably not faulty but they could have chosen a font working fine for the screenshot...

Then the good one, they changed the clock font (maybe it was already in KDE 4.0 I did not check). This is no longer the ugly segment display \o/

Update: Official announcment screenshot looks better and does not have the font issue.

optimiser la place disponible sur la xandros de l’eee

2008-07-28T14:21:26+00:00

au bout de quelques jours/mois d’utilisation, vous avez personnalisé votre menu avec asustools, vous avez fait des modifications avec Tweakee, et vous avez changé les versions des logiciels que vous utilisez le plus souvent. (passage de OpenOffice 2.2 à openoffice 2.4).

Mais voilà, tout ça prend de la place.

En effet, la possibilité de revenir à l’état d’origine de l’eee en appuyant sur F9 liée à l’utiliation d’Unionfs, fait par exemplen, que lors de l’installation de openoffice 2.4.1, l’ancien n’est pas enlevé et le nouveau rajouté.

le but de la manoeuvre ici expliquée est de rendre définitfs les modifications que vous avez apportés à l’instant t.

Les grandes étapes :
* sauvegarder le disque dur et la partition 2 séparément
* redimensionner la partition 1 et 2 pour gagner de la place sur le sytème.
* effacer les fichier qui sont dupliqués sur la partition 2
* copier les fichiers

sauvegarder le disque dur et la partition 2 séparément

Copier le disque dur est une sécurité. Quand on touche ainsi aux partitions, c’est fondamental.

Il faut lancer un linux autre que la xandros de l’ee pour pouvoir toucher en toute liberté au système de fichier. Personnellement, j’ai une mandriva installée sur un dd externe qui me servira aussi d’emplacement de sauvegarde (il faut 6go de libre). Dans ce cas, le disque dur interne de l’eee est appelé /dev/sdc . Ceci peut changer en fonction de ce que vous utilisez.

Sauvegarder le disque dur :
dd if=/dev/sdc of=/media/xandros_image_disque.img

Sauvegarder la deuxième partition (non nécessaire si vous savez utiliser losetup et fdisk pour la monter directement depusi l’image précédente. Si vous ne voyez pas de quoi je parle, sauvegardez la !!)

dd if=/dev/sdc2 of=/media/xandros_image_partition_2.img

Redimensionnment de la partition 1 et 2 : (garde normalement les données de la partition 1)
fdisk /dev/sdc
d (delete)
1
d
2
n (nouvelle)
p (primaire)
1
appuyer sur entrée (valide la premier cylindre. 1 normalement)
choisir le nombre de cylindres (perso, je suis passé de 300 à 420)
t (définir le sytème de fichier)
83 (linux)
n (nouvelle)
2 (son numéro)
entrée (cylindre de départ)
entrée (la fin de l’espace libre)
t
83

voilà, on a repartitionné le disque. Reste à récupérer le système de fichier de la partition 1 :
resize2fs -f /dev/sdc1 (on lui dit de prendre toute la place dispo)
e2fsck -f /dev/sdc1 (petite vérification)

on s’occupe de la partition 2 : (si ca pas formaté, ça plante au boot)
mk2fs.ext3 /dev/sdc2

Maintenant on peut s’occuper de transférer les données.
(tout ceci est tiré de http://wiki.eeeuser.com/howto:removeunionfs

mkdir /media/part1
mount /dev/sdc1 /media/part1

mkdir /media/part2
mount -o loop /media/xandros_image_partition_2.img /media/part2

cd /media/part2

find . -name .wh.__dir_opaque -exec sh -c ‘F=”{}”;echo rm -rf /media/sda1/${F%/*}’ \;
(enlever le “echo” pour que ça le fasse vraiment)

puis :
find . -name .wh.\* ! -name .wh.__dir_opaque -exec sh -c ‘F=”{}”;echo rm -rf /media/part1/${F/\/.wh./\/}’ \;

(enlever le “echo” pour que ça le fasse vraiment)
Note : ces opérations enlèvent les liens symboliques du système de fichiers UnionsFS pour préparer la copie.

Ensuite, il reste à copier :

cp -a sbin etc bin usr home lib var opt dev /media/part1/

Cette opération dure un certain temps. Ensuite, un petit

sync

vous permet d’être sur que tout s’est bien passé et que tout est écrit sur les disques.

Ensuite, vous pouvez redémarrer. Normalement, tout redémarre et vous avez un système tout beau, pas propre, mais qui est juste ce qu’il vous faut. Et vous bénéfichiez de la possibilité de restauration via F9.

Note : vous êtes dans la mouise, une opération s’est mal passée…

dd if=/media/xandros_image_disque.img of=/dev/sdc

et voilou Merci la sauvegarde.

À propos de mon ( relatif ) silence

2008-07-27T10:36:08+00:00

Eh, cela faisait longtemps que je n'avais posté de billets concernant Linux, et surtout Mandriva. Je dois avouer qu'après un mois de Mai/Juin très chargé avec la sortie de la Mandriva 2008.1 Spring ( rédaction d'articles ), et mon déménagement à ma nouvelle adresse, j'ai décide de prendre un peu de recul. Cependant j'ai continué à suivre l'actualité du Libre et notamment de Mandriva. J'en ai notamment profité pour commencer à migrer sous KDE4 et à tester l'environnement en profondeur. Je serai bientôt de retour, et je pourrais me consacrer davantage à Linux et aux logiciels libres. Cependant je dois avouer que prendre un peu de recul m'a fait du bien :)

XGL is dead

2008-07-27T09:48:41+00:00

So XGL, the evil hack done by Novell to make Compiz ( another hack IMHO ) is finally dead. Great, the right technology win ( AIGLX ) and there will have further improvements ( DRI2 ). The time for Compiz will come to an end also, but in a further future. At least with KDE4 kwin possibilities, Compiz will be less needed in the future. I guess that we will have further compositing effects integration in Metacity. Are we goign to have a Metacity+Compiz merger ?

Switched to Mandriva…

2008-07-27T09:05:11+00:00

I finally did it! Been talking about ditching Ubuntu for ages and never found the time (you know… backup, new install, restore, get familiar, etc.). It turns out that last Thursday while extending my /home partition with a LiveCD, for some reasons something went wrong and I ended it with my bigger partition having the same remaining free space as before being extended (I had a 20GiB unused space on the disk initially). Thinking I had been lucky not to lose anything, I backed up and installed Mandriva One. It’s a bit like going back to my first love Mandrake (second actually, started Linux with Red Hat when it was free many years ago)! Of course I preferred the name back then, but for obvious reasons they couldn’t keep it.

So Mandriva has actually a specific ISO file for Asia which can be downloaded from a Chinese mirror maintained by our good friend Funda. It includes all the necessary files to support Chinese, Japanese, Korean, Indonesian, Malay and a few more languages I think. Installation was almost ok, couldn’t do it in 3D mode but hey, I can live with that (the install button just wouldn’t click).

The first 6 hours using Mandriva where a bit challenging in the sense that I had to get familiar with urpmi and how to do things. They do have a great Linux Control Center (mcc) where you can find all the things to be configured in one single location. Their network manager is also very powerful and has all the options one should expect from such a tool. Had a little rendering problem with my Chinese fonts (using English desktop with Chinese enabled) which was due to a conflict with the Japanese fonts. Well in short after two days of discussion with Patrick who visit us regularly, Funda and Freeflying on #mandrivacn I got everything fixed, missing applications from the repositories backported and a service that really impressed me: Kudos to Mandriva and its community.

Now an other reason for supporting Mandriva is that they’ve been trying to build a community here, have hired people to improve Chinese support and are even building the operating system that will run on the Gdium (the Loongson based general purpose Chinese CPU). So definitely an interesting distribution worth following and encouraging.

I again extend a big thank you to Funda, Freeflying and Patrick for their help, and recommend everyone to give it a try.
