Re: Making pbuilder just that little bit faster

It is true that making /var/cache/pbuilder/build a tmpfs makes a noticeable speed difference. But it seems you cannot cache the downloaded debs: ln: creating hard link ...: Invalid cross-device link.

Testing SMART status of my USB harddrive

December 7th, 2009

I recently bought an external USB harddrive, made by Toshiba. It’s the HDDR500E03X model with 500GB space, internal shock sensor and ramp loading technology. Now yesterday I learned, that I can also cover its health status using the smartmontools. The usb* device types did not fit, but the sat type worked. It is as easy as running:

smartctl -d sat -c /dev/sdb
smartctl -d sat -t long /dev/sdb

Toshiba Tecra A10 (PTSB5E) - Part III

November 27th, 2009

Connecting a NOKIA 6310i mobile phone via serial DLR-3P cable and the serial connector of the laptop (for Bluetooth see part II): After installation of the gnokii package(s) the the configuration file says:

model = 6510
connection = dlr3p

Then gnokii reports:

$ gnokii --identify
GNOKII Version 0.6.28
IMEI         : XXXX
Manufacturer : Nokia
Modell       : 6310i
Product name : NPL-1
Revision     : V 5.22

Toshiba Tecra A10 (PTSB5E) - Part II

November 26th, 2009

So I got a little bit further with my little toy.

Bluetooth

Bluetooth works. The packages gnome-bluetooth and bluez are installed and the kernel module bluetooth is loaded. hciconfig reports this:

# hciconfig
hci0:	Type: USB
	BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 310:10 SCO MTU: 64:8
	UP RUNNING PSCAN
	RX bytes:11354 acl:105 sco:0 events:286 errors:0
	TX bytes:4012 acl:99 sco:0 commands:66 errors:0

I tried to connect to a SAMSUNG and a NOKIA mobile phone. After enabling visibility of the phone the bluetooth-applet (gnome-bluetooth) showed the device. However I got an error saying “The name org.openobex was not provided by any .service files” when trying to access the mobile device. This was solved by installing obexd-server obex-data-server. Then I was able to access the phone contents via Bluetooth.

Virtualization

I recently tried to debug the mopac7 build error. I installed the qemu(-qemu-kvm) emulator. Loading of the kvm_intel module failed with “kvm: disabled by bios”. But this was easy to solve by enabling the Intel virtualization technology in the BIOS: push and hold the ESC key during startup until the laptop tells you to press the F1 key. Then enable the related BIOS option and done.

Good bye Warren, …

November 7th, 2009

A tragic loss has hit the open source software community. Warren Lyford DeLano, among other things, open source advocate, scientist and the author of the famous PyMOL molecular visualization system, suddenly passed away at the age of 37. I remember you as a genial, pleasent intelligent guy and software author. It has been a pleasure to work with you. Good bye.

Toshiba Tecra A10 (PTSB5E) - Part I

November 3rd, 2009

I recently got a Toshiba Tecra A10-1HU laptop. This is a series describing my experiences with this hardware using Debian Sid.

This one comes without any operating system. So I got a recent testing-netinstall CD-image and ran the installer procedure (in expert mode). Everything went fine and I ended with a shiny Squeeze and kernel 2.6.30. Because I use Sid as my usual system, my first action was a dist-upgrade to Sid.

Things that worked out-of-the-box:

Display/Graphics (Intel GMA 4500M HD)

The integrated graphics chipset, an Intel GMA 4500M HD, works with the xserver-xorg-video-intel package and the default X.org configuration. No custom /etc/X11/xorg.conf is necessary.

The (IMHO non-reflecting?) display runs at 1280×800 at 60 Hz.

Cable network device

The integrated Intel 82567LM Gigabit Network device works with the e1000e kernel module. No customization was necessary.

Touchpad/Trackpoint

The notebook comes with the so called Toshiba Dual Pointing Device a touchpad (+2 buttons) and a trackpoint (+2 buttons). Both worked without customization.

Energy savings/Suspend/Resume

apmd and acpid handle this. No problems yet. Suspend/Resume works. I did not yet test (and I’m not sure if I should) hibernate and uswsusp.

Webcam

The webcam is a CNA7157 model or at least detected as such. The video4linux modules handle it and the cheese application produces pictures.

Volume-control wheel

It works. Module and package information will follow as soon as I figure them out.

Things that needed customization

WLAN (Intel WiFi Link 5100)

The notebook comes with an Intel WiFi Link 5100 device. It does not work out-of-the-box. Following this article, I’ve installed the firmware-iwlwifi package and loaded the iwlagn module.

Sound (Intel)

For the sound device to work the snd_hda_intel module is necessary. Further the following lines must be added to /etc/modprobe.d/alsa-base.conf

# not sure about the first line, start adding the second only
options snd-cmipci mpu_port=0x330 fm_port=0x388
options snd-hda-intel index=0 model=toshiba position_fix=1

Unsure/Not yet working

Temperature sensor

After installing the sensors-applet I got two identical temperature displays. I’m not sure what they show. Anybody an idea how to examine this?

Modem

The notebook comes with an internal modem device:

00:03.0 Communication controller [0780]: Intel Corporation Mobile 4 Series Chipset MEI Controller [8086:2a44] (rev 07)

From what I read I need hsfmodem or the sl-modem packages. “Unfortunately” the latest version is not available for amd64 from the archive, although it seems to have been built.

Untested

I did not yet test

  • Bluetooth (icon there, kernel module loaded)
  • Firewire (kernel module loaded)
  • Card-reader (kernel modules loaded)

Green IT - a GSoC topic?

September 17th, 2009

I’m back from the conference at Berlin “Faktor X - Tag der natürlichen Ressourcen”, a side-conference of the World Resources Forum 2009 in Davos.

It was pretty interesting, although the topic is not new. If you don’t know it: We are running out of (several) resources. The main topics going through the media are often “energy” and “oil”. Well, several metals will become much more problematic much more earlier! So, what is the aim: material-, product- and production-efficiency and recycling/upcycling(/downcycling).

One of the topics mentioned at the conference was the IT industry. One of the keywords is “green IT” - more efficiency through IT, more efficiency by more efficient hardware, better recycling of hardware, …. Another point was “more efficiency by more efficient software”. One of the questions mentioned was “how much resources costs a click at google”. I think, one can adapt this question to almost every software. We have several software, which is widely used. I’ll just mention the apache web-server. Would’t it be good to know, that this widely used software won’t waste CPU cycles for nothing?

So what about a GSoC project checking such “often/widely used” software for efficiency (besides checking for buffer or heap overflows or NULL pointer dereferences)? Can anybody imagine such a project? What is your opinion?

Writing manual pages in GROFF (1)

September 15th, 2009

I always wanted to write a short howto for Debian package maintainers, how to write a manual page in GROFF. This is useful for short documents (for longer documents, docbook/docbook-xsl can be a good choice). I already have written some parts. However, here is the first part of hints. More might follow later.

The delimiter in the NAME section

The name section is (probably) the only place, where exactly one hypen-minus \- must appear. The hyphen-minus is the delimiter between the command name and one-line description.

.SH NAME
foo-bar \- foos the template foo-what-bar

Typical mistakes regarding paragraphs

Using a .PP macro directly following a .SH or .SS macro is useless. This macro should be used between paragraphs:

.SH OPTIONS
The program follows the usual GNU command line syntax, with long options starting with
two dashes (`\-').
.PP
A summary of options is included below.

Options/File descriptions

To describe options or files it’s usually useful to make use of the .TP macro.

.SH OPTIONS
.TP
.B \-f, \-\-force
Force the execution of the specified command.
.SH FILES
.TP
.I ~/.foobar
Per user configuration file.

To create more than one intended paragraph the .IP macro can be used.

.TP
.B \-f, \-\-force
Force the execution of the specified command.
.IP
This option has no effect in conjunction with \fB\-\-foo\fP.

Avoid hyphenation in URLs/URIs/paths

Usually we don’t want URLs or URIs to be hyphenated. This can be done using the \% sequence. Typical examples:

A short tutorial is available online at \fI\%http://foo.tld/some/path/here/manual.html\fP.
On a Debian system the complete text of the GNU General Public License
version 2 can be found in the file \fI\%/usr/share/common-licenses/GPL\-2\fP.

Referencing persons and their mail address

The common markup is to write the person name in bold letters and the mail address in roman letters is put into angle brackets. It’s usually a good idea to mark where the mail address starts and ends. We can use the \& sequence as shown in the following example:

\fBDaniel Leidert\fP <\&daniel.leidert@wgdd.de\&>

Abit AirPace, ath5k and eduroam

April 10th, 2009

I tried to connect my university workstation to the wireless eduroam network on the campus. The workstation was delivered with an Abit AirPace wlan card (probably an Atheros 5006 chipset). The first thing necessary was the ath5k kernel module (my first shot using ndiswrapper didn’t work). Both Debian lenny and Ubuntu intrepid-updates provide it.

Now there are generally 3 ways to connect to the AP. All making use of wpasupplicant. Further the certificate (may differ for the universities) is necessary.

/etc/wpa_supplicant/wpa_supplicant.conf

This is described at the sites of my university. It’s written in German, but it should still be easy to understand. Let’s just mention the snippet for /etc/wpa_supplicant/wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=2
ap_scan=1
fast_reauth=1

network={
	ssid="eduroam"
	key_mgmt=WPA-EAP
	proto=RSN
	pairwise=CCMP
	group=TKIP
	eap=TTLS
	anonymous_identity="anonymous@tu-dresden.de"
	identity="****@tu-dresden.de”
	password=”****”
	ca_cert=”/etc/wpa_supplicant/TUD-CACert.pem”
	phase2=”auth=PAP”
}

Instead of the script suggested at the site above, you can also use this snippet in /etc/network/interfaces:

auto wlan0
iface wlan0 inet dhcp
	wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

/etc/network/interfaces

It is also possible to put the values directly into /etc/network/interfaces:

auto wlan0
iface wlan0 inet dhcp
	wpa-ssid eduroam
	wpa-proto RSN
	wpa-group CCMP TKIP
	wpa-pairwise CCMP TKIP
	wpa-key-mgmt WPA-EAP
	wpa-eap TTLS
	wpa-ca-cert /etc/wpa_supplicant/TUD-CACert.pem
	wpa-phase2 "auth=PAP"
	wpa-anonymous-identity anonymous@tu-dresden.de
	wpa-identity ****@tu-dresden.de
	wpa-password ****

network-manager

Here is a screenshot of the authentication dialog.

So now everybody at the University of Dresden wanting to use eduroam should hopefully be able to configure this connection on his Debian/Ubuntu system.

(WW) AllowEmtpyInput is on, devices using drivers ‘kbd’ or ‘mouse’ will be disabled.

April 10th, 2009

Maybe you will observe a changed mouse and keyboard behaviour after updating X.org recently in Debian Sid. Then you will probably discover the warning mentioned in the title in your X.org server log /var/log/Xorg.0.log. The very short and dirty solution to get things working for the moment is to put this into your /etc/X11/xorg.conf:

Section "ServerLayout"
    Option "AutoAddDevices" "off"
EndSection

See the first entry in /usr/share/doc/xserver-xorg/NEWS.Debian.gz and follow the mentioned links for more information. However, the above solution should only be a temporary workaround: Try to migrate things (I will post changes for my system asap).

Network doesn’t come up after update to udev 0.140

March 30th, 2009

The recent update to udev 0.140 lead to a system without network access to me. The error messages were:

done.

It seems, the update added rules to /etc/udev/rules.d/70-persistent-net.rules by increasing the device number and applying the last applicable NAME directive instead of the first one. This lead to the following file here:

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="XX:XX:XX:XX:XX:a7", ATTRS{type}=="1", NAME="ath0"

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="XX:XX:XX:XX:XX:18", NAME="eth0"

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="XX:XX:XX:XX:XX:XX", NAME="eth1"

# PCI device 0x10ec:0x8139 (8139too)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="XX:XX:XX:XX:XX:18", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

# PCI device 0x168c:0x0013 (ath_pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="XX:XX:XX:XX:XX:a7", ATTR{type}=="1", KERNEL=="ath*", NAME="ath1"

So the devices created were eth2 and ath1 but /etc/network/interfaces contained entries for eth0 and ath0. So fixed /etc/udev/rules.d/70-persistent-net.rules and rebooted.

<rant>Is it really necessary to break network access with an update???</rant>

Update

I forgot this one: #521521.

Debian/Ubuntu packages of bluefish-unstable for amd64

March 6th, 2009

Debian- and Ubuntu-packages of bluefish-unstable - the development series of bluefish - for the amd64 architecture are now available.

Update to Lenny

February 17th, 2009

Now that Lenny has been released I’ve updated some machines and found just one flaw. There is a cvsd installation, which has been extended with an OpenSSH server. After the upgrade the server refused the connection. Enabling debugging output showed:

sshd[...]: fatal: ssh_selinux_getctxbyname: ssh_selinux_getctxbyname: security_getenforce() failed

in the log. Searching the web a bit revealed, that the CHROOT now needs a mounted /proc. Done and everything works :)

Danke! Gratulation! … Und tragt keine Trauer!

Gratulation und ein riesiges “Danke!” an unsere Deutsche Nationalmannschaft für diese schöne und eigentlich grandiose Europameisterschaft. Ihr habt uns auch ohne den Titel Spaß und Freude gebracht und das Sommermärchen fortgesetzt. In 2 Jahren geht’s weiter ;)

/usr/lib/python2.3 garbage

May 16th, 2008

Yesterday I stumbled about files and dead symlinks left in /usr/lib/python2.3/site-packages/ on my Sid box. These files/symlinks seem to have been shipped/created(?) by:

python-ldap python-cairo python-crypto kiki python-foomatic python-mysqldb
python-logilab-common python-egenix-mxtools python-numarray python-pygresql
python-imaging-sane python-imaging python-xml python-reportlab

Deleting /usr/lib/python2.3 (dpkg -S didn’t show any package relationship nor did I find something in /var/lib/dpkg/info/) and reinstalling the above mentioned packages did not recreate the files/symlinks. So it seems the directory can be safely removed. Maybe I missed some announcement or one (or more) packages need to be fixed. No time to examine it atm.

Update

This is known as Debian bug #409390. Thanks to Josselin Mouette for the information.

[DSA 1571-1] New openssl packages fix predictable random number generator

May 14th, 2008

Ok, shit sometimes also happens to Debian users.

Now I read a lot of FUD, flames, arrogant claims and much more bad things, including blaming of downstream in general.

Well, Debian maintainers are NOT upstream authors. Maintainers often care about a lot more than just 1 package. Now I wonder if one can really expect, that maintainers know the source code of their packages as good as upstream authors do? Is this, what the user or the Debian project expects from a package maintainer? I agree, that this would be the ideal situation. But how realistic is it, if one maintains 10, 20 or more packages?

Normally users report us issues. We take a look at the source, try to catch the issue, track it down and fix it. And IMHO in almost all cases this is enough and it lets us handle several packages. And maybe this is also, what happened here. The maintainer got a report, tracked it down and tried to fix it. It seems, he posted it to the openssl-dev list, which is to my reading considered for such questions, and got a positive response. And with fixing it, he made a horrible mistake. But apparently it also seems, that the question had been discussed earlier more than just once (I wish, the OpenSSL guys would have created the FAQ entry earlier).

I don’t want to blame the maintainer for doing this mistake. We are humans. But do we need another instance, that (periodically) checks (probably only Debian-specific) patches/changes to security relevent software or do we need different requirements for maintainers of such software [1] or should we simply archive this under “Shit sometimes happens … even to Debian users”?

[1] Consider gnupg which is currently almost unmaintained. It also has Debian specific patches applied and I wonder, which skills the new maintainer should or must(?) have (IIRC this question was raised in the linked threads too)?

Sorry

I’m sorry for any inconvenience you had yesterday or today trying to access my web services. But I had to perform some long standing maintenance tasks. The service is now running again. If you still observe problems, please don’t hesitate to tell me.

DIN bestreitet Verfahrensmängel bei der Abstimmung zu OOXML mit 7 zu 13 Stimmen

March 31st, 2008

Wie vor wenigen Tagen veröffentlicht, hat das Lenkungsgremium des DIN-Normenausschusses Informationstechnik und Anwendungen (NIA) entschieden, dass bei der Abstimmung zum OOXML-Schrott “nach formalen Kriterien der Prozessablauf in der ISO nach Meinung des Lenkungsgremiums” nicht “fehlerhaft gewesen sei”.

Bei gerade einmal 7(!) von insgesamt 20 Stimmen, die dafür stimmten (6 stimmten explizit dagegen und eine Ja-Stimme holte man sich auch noch vom hauptamtlichen Mitarbeiter des DIN), bleibt mir nur zu sagen: Wohl kaum, liebes DIN! Mit diesem Ergebnis dann auch noch von einer “falschen und irreführenden” Berichterstattung bei den objektiven Berichterstattern zu sprechen, ist einfach nur unverschämt. Wenn gerade einmal 1/3 der Stimmberechtigten votieren, dass ein Verfahren keine Verfahrensmängel hatte und das als Beweis dieser These herangezogen wird, dann spreche ich von einer falschen und irreführenden Berichterstattung bei der DIN.

“Einschüchterung” hier und “Gelassenheit” da

March 20th, 2008

Gestern hat das Bundesverfassungsgericht per Eilentscheidung die Vorratsdatenspeicherung zunächst einmal eingeschränkt. Dabei bescheinigten die Richter dieser Maßnahme einen “erheblichen Einschüchterungseffekt”. Der stellvertrendende Regierungssprecher Thomas Steg sagte dazu: “Im Kabinett jedenfalls ist die Entscheidung nicht lange diskutiert worden und sie ist mit großer Gelassenheit zur Kenntnis genommen worden.”. Wie bitte? Mir ist nicht ganz klar, wie sich die Einschüchterung der Bevölkerung mit der freiheitlich demokratischen Grundordnung vereinbaren lässt. Offenbar ist diese Regierung an letzterem nicht länger interessiert, sonst hätte man die Aussage der roten Roben nicht mit großer Gelassenheit zur Kenntnis genommen.

Es bleibt nur zu hoffen, dass das Bundesverfassungsgericht die Zugriffsmöglichkeiten und die Speicherfristen in seiner endgültigen Entscheidung weiter beschränken wird. Nach bisherigem Vernehmen wird das Gesetz selber wohl nicht gekippt werden (AFAIK und IANAL).

Diploma exams are calling: Please read if you want to NMU my packages

March 16th, 2008

Because my diploma exams are getting nearer, I have to reduce my contribution to the Debian project for the next two months (up to mid/end of May). There is fortunately currently not much to do for me and also no need to NMU my packages. But please read the following notes, if you (still) think there is a reason for a NMU:

GCC 4.3 transition

Done. All related packages have been fixed. My sponsor just needs to upload psicode to fix the last outstanding bug.

PS: Also the build-twice-in-a-row release goal will be reached by the upload of the apbs update by my sponsor.

gfortran transition

Almost done. mpqc already reached the buildds. ghemical has been uploaded, but waits for mopac7 and libghemical, which are in NEW because of the new library names.

apbs and psicode already have been transitioned.

Other bugs

Ok, I’ve closed almost all relevant bugs in my packages. There are a few outstanding bugs that should be examined for Lenny and can be fixed in NMUs - preferable via delayed NMU queue and an information to the debichem group:

#420795: chemical-mime-data: Unknown media type in type ‘chemical/x-*’
Upstream bug tracker for shared-mime-info contains some more information, how to deal with this. Patches/ideas welcome.
#438694: gabedit: Crashes when loading any XYZ format file
Looks tricky. Maybe an OpenGL issue related to some video card drivers. Not sure.
#442223: openbabel: some connect information lost when convert from pdb to txyz
Nothing examined yet to solve this bug.
#464867: extrema: conflicts with psi3 package
Hope, my team will cover this asap.
#465723: mopac7 — please do not use g2c.
There is currently a workaround using f2c to solve this bug. But MOPAC7 has been written in FORTRAN and we can use gfortran and drop f2c completely. See the report for more information. This is something I would like to see in Lenny.

For the xmlto package it was planned to add the dblatex toolchain for PDF/PS/DVI creation because passivetex will very probably never have a comeback in Debian and docbook-xsl/fop is not fully main and cannot create DVI output. In the case you want to help, feel free to add this feature by NMU to experimental (maybe with version 0.0.21~dblatexX.Y). A first patch is available in bug report #416622.

New upstream releases

It is possible that there will be a new upstream release for docbook-xsl in the near future. DO NOT consider uploading it by NMU if you did not test it! This upcoming release ships manpage stylesheets, that have been rewritten in large parts. So regressions can be expected. Fortunately Michael Smith and me agreed, that we should test it carefully, before the release is done. Unfortunately I will not have the time to do it. So if you consider uploading it, please get in contact with Michael (xmldoc) and offer your help testing it. He added (and I hope, many Debian packagers and packaging groups will like that) some kind of regressions tests. These tests build the manpages from several Debian packages: e.g. samba, apt, aptitude, git, fglrx and some more. There are further some new supported features, that should be added to the manpage example shipped with the Debian package. I also planned to split the source package (atm, docbook-xsl and docbook-xsl-doc tarballs are merged together for Debian) as soon as docbook-xsl-ns is packaged - which I wanted to do with the next upstream release. So consider all of the above notes if you plan an NMU to upload a new upstream release and in question, mail me and wait for my answer (which will need some days).

In all other cases, new upstream releases should be easier to handle.

ITPs

All my ITPs are delayed. However if you plan to still upload one of these packages, you should consider the following notes:

docbook-xsl-ns
See the above note about docbook-xsl and the source package split.
html-xml-utils
Already in a good shape, but I sent upstream some patches to improve the manpages. Version 4.6 of the html-xml-utils should contain these patches and this version should be uploaded into Debian. With this version, Bert Bos will probably also decide, which prefix will be used for the binaries (they have very generic names atm; the prefix will probably be hx- or hxu-). Waiting for this releaes therefor is IMHO a good choice.
DocBook 5
I already found a problem that need to be addressed in the package: Where to install its catalog? You will see, that there is already a catalog file in /usr/share/xml/docbook/schema/dtd/ shipped by the docbook-xml. Now I’m not sure, what to do here. Upstream ships one catalog file for all supported schemas (RNG, DTD, W3C schema and schematron), so maybe the catalog file can go into /usr/share/xml/docbook/schema/. Really not sure atm. The answer to this question might affect the Debian XML policy and should be made carefully.

QA work/fixes

Several lintian warnings have already been fixed in the SVN repositories used for my packages but have not yet been uploaded.

I really only plan to reduce my work during the preparation and the exams. So whatever you do, please try to make it easy for me to continue my packaging work after the exams :)
