That would be a good reason :)
Except that I can't reproduce your results, or understand how
they're relevant to Brett's question :(

Curious...
Are you running Debian Linux?

Which release?

pciutils 1:3.1.9-6

"Recommends" for hard dependency?

[Shriramana Sharma]

Hello people. This is about:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=747716

Currently libqt5sql5-sqlite is given as a recommends and not a depends
for qttools5-dev-tools
(https://packages.debian.org/sid/qttools5-dev-tools) whereas
/usr/lib/x86_64-linux-gnu/qt5/bin/assistant, one of the programs
installed by the latter package, cannot even start up without
libqt5sql5-sqlite being installed. I hence requested to change it to
depends.

The developers say "no, recommends is right in this case since only
assistant requires it and the other tools in the package do not -- you
should have recommends installed by default in your system in most
cases -- if you don't, that's not a problem of the packaging".

I pointed out that the specification at
https://www.debian.org/doc/manuals/maint-guide/dreq.en.html#control
says to use depends "if your program absolutely will not run ...
unless a particular package is present." That guide does not speak
anything about multiple programs installed by a package, but IMO it
stands to reason that what is logical for one program installed by a
package applies for many programs installed by a single package as
well.

IOW, if I install a package I expect to be able to run all the
programs provided by it. Without a recommends being installed
alongside, maybe some of the functionality of those programs is
missing, but it should not fail to start altogether, which is what is
happening in this case.

IMO something that a program can't even start without should be a hard
dependency and not just a recommends. A user may disable installation
of recommends for whatever reason. This should not prevent the user
from even starting up the program!

I am posting this here since the developers seem to just disagree with
my point without providing any policy-based/logical reason. I want the
community to weigh in with their opinion as well.

Thanks.

This is shown when I do apt-get upgrade, that's all.

I am wondering why, when I do an apt-get dist-upgrade, I get one or
two 'changelog' or 'news' type entries out of nearly a gig of updates?

I would expect many many more, or none at all. I don't understand.

Thanks again,

Confusion

[Joshua Anthony]

My apologies to those who feel that I have wasted their time and thanks to 
those who have tried to help.

I don't know how I managed to start two threads but this whole business well 
illustrates the confusion that I originally wrote about.

The 'technical' question was 'Why does exactly following the process that has 
worked perfectly well for other distros, using exactly the same hardware, fail 
when I try to install Debian the same way?'

The confusion was - and is - how do I separate my rather elementary and 
unsophisticated question from the mass of expert questions from sophisticated 
users so as to get an answer I can understand without irritating them and 
wasting their time?

That, I suppose, is a 'procedural' question, and I probably ought to have asked 
it separately.

I'm happy to drop this now, as it certainly hasn't worked for me, and look 
elsewhere for answers.

Josh.

You don't say it but I'm guessing you checked your Options allow
directive (Indexes, between Directory tags) in your .htaccess files
(also allow under mod_access_compat/*mod_authz_host*)

No.

NoScript does not block Flash by default - you could make it, and
likewise with AdBlock Plus, and /etc/hosts. Perhaps it's your use of the
term "redundant" that's problematic?

No.

It doesn't.
(so, no, again).

For empirical evidence go visit Youtube with *just* NoScript enabled and
compare the page load speed and totals with NoScript *and* FlashBlock
both installed.

Why?

Why when searching for "audio" would you need case-insensitive??

Multimedia *audio* controller


An extra three keystrokes for no gain. Extra noise, no signal.

kernel security upgrade bollixed need help

[Paul E Condon]

I was responding to a recently received security message about the
linux kernel in Wheezy. I thought I had things configured so that the
repaired kernel would come from the security repository automagically,
but ...

It did appear to be downloading a new kernel and installing it, but
when it finished nothing appeared to have been changed. I can't retry
because my system appears to have set flags that the upgrade has been
done. but there are no new files in /boot or updated symlinks in /.

This should not be, IMHO. Please ask the questions that need to be asked.
Note: I am attempting to respond to a security alert, not merely getting
the latest kernel via wheezy-backports. Or has the system changed to
a newer way in which wheezy-backports should be used. If so I will definitely
need a link to explicit steps.

Re: Kernel fails to detect internal hard drives after routine apt-get upgrade

[O]

Thank you Selim, Stan.

 I will instal apt-listbugs.  I clearly need it!

Unfortunately, I instead opted to install a backported kernel (3.13.x),
which was able to see and mount my drives.  But then, flgrx (ATI
proprietary graphics driver) was not being loaded by/in the kernel.  So I
tried to remove it, and this broke the package, so that I'm now in dpkg
hell.

I'm curious: is there a way to *only * install "security updates" in order
to avoid other kinds of "fixes" that can cause problems like this?

Having said that, I hasten to add: thank you everyone and thank you
Debian.  Debian stable has been free of major issues like this for 4 years.

The problem is a patch/commit added in 3.2.57-3 meant to fix one problem
but caused another more serious problem--unable to boot or register the
drives.

Since you can boot an older kernel, there is no need to use a rescue CD.
 Simply boot the older kernel and manually install the latest 3.2.x
available prior to 3.2.57-3, using apt or aptitude.

$ aptitude search linux-image

will show your the kernel versions available in your configured
repositories.

Cheers,

Stan

Re: I need to hear PC Speaker Beeps through the Audio Output.

[Martin G. McCormick]

I performed lsmod on the system in question and it does show
that lsmod loads but the second column is headed as "used by"
and there is a 0 there which sounds like nothing is using it. Is
there something I need to do to get it producing sound over the
audio output jack?
As I previously described, I get perfectly good stereo
sound via alsa just no terminal beeps. I have the 'beep' utility
installed which also makes use of the PC speaker not the sound
card. If I tell beep to emit 400 for 10 seconds by
beep -f400 -l1, it comes out that piezo buzzer for 10
seconds. Absolutely nothing comes out through the sound card
that sounds like a 400 HZ square wave tone.

The amixer settings for this particular sound card show
Beep turned on and set for full volume. I am not sure if that
means the hardware input on the sound card or audio input from a
driver. Severl older Dell systems I have will relay the PC
speaker's audio if you tell amixer to open the appropriate audio
channel but they also have physical connections to the mother
board's speaker driver which comes from the BIOS post test.

Text files treated like html in apache 2.4

[Stephen Powell]

My troubles with Apache 2.4 continue.  With Apache 2.2, if I entered in
the address bar of my browser

   http://my.server.ip.address/xyz/abc.txt

and abc.txt was a plain ASCII text file in /var/www/xyz, then the browser
would display it as preformatted text.  That is, it would look the same
as if I viewed it with less, or vi, or some other text editor/viewer.
But with Apache 2.4, it treats the text file like html and reformats
everything, concatenating lines, eliminating blank lines, etc.  How do
I get it to treat plain text like plain text again?

Can't get Apache to display a directory

[Stephen Powell]

I recently upgraded a back-end server from wheezy to jessie, and with the 
upgrade,
Apache went from 2.2 to 2.4.  There are a lot of changes to Apache between 2.2
and 2.4, especially in the area of authentications, authorizations, etc.
One difference that I have not been able to figure out is how to allow access
to a directory.  I'm not talking about allowing access to the files in the
directory, I'm talking about access to the directory itself.  On apache2,
for example, if I had a directory called xyz in /var/www, I could type in
the address bar of my browser something like this:

http://my.server.ip.address/xyz

And it would show me a list of files in the xyz directory.  I could then click
on the filename of one of the files in the directory and see that file.
But with the new apache server, I get a "404 - not found" error.  I have
looked at the apache documentation, but cannot figure out how to accomplish
what I want.  How do I get this to work?

Basically, I want a configuration that allows all users to view all documents
and all directories under /var/www/html.  I don't want to have to define
userids or passwords.  No authentication of users will be done.

I happened to notice the following bug report while updating last week:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746642

Basically, it seems like people solved this by booting from a rescue
disk and downgrading to an older kernel.

After you fix your system, I recommend installing the apt-listbugs
package.  That's what showed me the bug report while updating.

Why don't you have it? It'll reduce the amount of page you need to
download ($ netstat --iinet will show you connections).
:)

You 'should' also have these installed:-

NoScript
FlashBlock

Kind regards


As a side note, doesn't NoScript and FlashBlock have redundant features, 
in that they both block the loading of Flash content?


So, shouldn't you just use NoScript, since it has more features and 
additionally does what FlashBlock does, anyway?

I am therefore wondering whether, somewhere, packages exist (.deb

the firmware ISO's.


By "installation" do you mean "drivers available *during*

(I have some small scripts I use to customise netinstall images if you

If you mean *after* installing Debian, then yes.
firmware-linux-nonfree and firmware-linux-free are the main packages.
$ apt-cache search firmware # for lots more


I do not know whether the firmware ISO's allow a user to choose which
desktop environment is installed,

Yes. They are identical to the "normal" install CDs, they just include
firmware.



and the procedure that I found, for
dealing with the .tar.bz files from the Realtek web site, seem too
complicated.

Do you have a link for that?


Thank you in anticipation, for constructive assistance.

[Debian 6 Squeeze] ANNOUNCEMENT: Intel processor microcode security update

[Henrique de Moraes Holschuh]

THIS ANNOUNCEMENT IS ONLY MEANINGFUL FOR PEOPLE USING DEBIAN 6 (SQUEEZE)
ON COMPUTERS WITH INTEL PROCESSORS.  IT DOES NOT APPLY TO THE MORE RECENT
DEBIAN RELEASES.


A new Intel microcode update is available for Debian 6 (codename Squeeze).

This microcode update is considered a security update.  Users of the newer
versions of Debian (stable/Wheezy, testing/Jessie, unstable) have already
received it.

For technical reasons, Debian 6 (Squeeze) will receive intel-microcode
updates only through squeeze-backports, and only after the same update has
been accepted into Debian stable, and pushed out into a Debian stable point
release.

INSTRUCTIONS ON HOW TO INSTALL THE UPDATE ARE AVAILABLE AT THE LAST PART OF
THIS MESSAGE.

This microcode update release contains fixes for a number of severe issues
on a large number of Intel system processor models produced in the last
five years.  Some of the issues fixed by this update address severe
security risks.

Details about some of the issues fixed by this microcode update, about
microcode updates in general, and about microcode update packages can be
found on previous emails on this thread, at:

https://lists.debian.org/debian-user/2013/09/msg00126.html
https://lists.debian.org/debian-user/2013/09/msg01300.html

Do not expect further announcements about intel-microcode updates, this is
an exception due to the known security nature of this update, and due to
the nonstandard process required to install it for the first time.


Installing the squeeze-backports microcode update:

Manual action by the system administrator is required to enable
squeeze-backports in apt's "source.list", and install the backported
intel-microcode and iucode-tool packages for the first time.

After the manual installation of the first update, apt will remember that
it has to get further updates from squeeze-backports.

Please refer to http://backports.debian.org/Instructions/ for general
details on how to use squeeze-backports, and below for step-by-step
simplified instructions.


First install procedure:


1. Enable squeeze-backports in /etc/apt/sources.list, adding:

   deb http://YOURMIRROR.debian.org/debian-backports squeeze-backports main 
contrib non-free

   notice that you need to enable both "contrib" (for the iucode-tool
   package) and "non-free" (for the intel-microcode package).

   This is safe.  In Debian's default configuration, squeeze-backports
   packages are only installed by direct request (-t option of apt-get,
   or by explicitly selecting the version from backports in aptitude).

   It will NOT cause your whole system to be updated to squeeze-backports.

2. apt-get update

3. apt-get --purge remove intel-microcode microcode.ctl

4. apt-get -t squeeze-backports install intel-microcode iucode-tool

   (notice that we had to explictly request that packages from
   squeeze-backports were to be used in step 4).


Update procedure:
-

Once installed, packages from squeeze-backports will be handled
automatically when you update the system.  The system remembers which
packages came from squeeze-backports, and looks there for updates.

1. apt-get update
2. apt-get upgrade (or safe-upgrade, or dist-upgrade)

A new microcode update is already available in Debian unstable, and should
make it to squeeze-backports in about four to six months.

That already happened. The device is there, otherwise I wouldn't be able
to mount it a second time.  But thanks for your input anyway.

Unfortunately, I cannot investigate this any further because I had to
reboot the system which cleared things up. But I would still like to
know how to fix such a situation.

I only noticed it because my backup script complained about the missing
path. Prior to running the backup, it checks whether the filesystem is
already mounted and mounts it if it is not mounted yet. That failed
because mount reported that the filesystem is mounted while the mount
point was empty.

Subject: I need to hear PC Speaker Beeps through the Audio Output.

Is there any kind of debian module that will reproduce
PC speaker sounds through the sound card?

The system in question has a working sound card but
there are no apparent pins on the mother board that carry the
timer-counter output to the outside world.

There is a piezo transducer on the board that beeps just
fine but there are no pins short of unsoldering the piezo
speaker and putting a couple of pins in it's place and that is
way too much work and the system does not belong to me. I need
to hear the beeps in headphones. The sound card even has a 2-pin
input marked PC Speaker but getting the signal there is the
issue which is why I am asking if there is a software-based
solution.
Thanks for any ideas.

Martin McCormick



Some mobos have a SPKR connection near the front edge.
That's for a real speaker. If yours has that, you could connect
it to the sound card. Otherwise, the other poster is correct:
there is no audio going to the piezo device, so you can't
use that signal for anything else.

We have a server running wheezy, and we named it D7Server (not

D7Server?  (It might matter, for example, if standards allow resolvers,
generally, to assume that names to be resolved will be lower case.)


If you consider DNS resolving only then you can use any case and upper
and lowercase will be the same.

But if you name your host with upper-case characters, you will face some
trouble on your local host. So you better not do it.





Ah.  Trouble on the local host is one of the problems we have.  The 
other is with a DNS resolver on the LAN (that resolver is not running 
Debian).  Name resolution is an issue in itself, and I was going to 
post separately with those details, but perhaps I could post here, to 
follow your remark.


Our difficulty is in stopping name resolution requests for hosts, that 
are local to our LAN, from going to a DNS resolver.  The machine I'm 
trying to setup is running wheezy.  Its name is D7Server, and the 
domain in /etc/resolv.conf is 'inet'.  The same issue seems to occur 
on some servers running earlier versions, as well.


I've read man hosts, resolv.conf, and nsswitch.conf; I've also had a 
look at

http://www.debian.org/doc/manuals/debian-reference/ch05.en.html#_the_hostname_resolution
(I'm assuming that's an official site).

On the Wheezy machine, /etc/nsswitch.conf contains

hosts:  files mdns4_minimal [NOTFOUND=return] dns mdns4

From my reading, since 'files' is listed first, /etc/hosts should be 
checked for name resolution first, with external requests to a dns 
resolver *only* if the host name is not found in hosts file.


But the behaviour I am seeing is that the box is asking for resolution 
(of its own hostname, actually) from an external resolver.  (That DNS 
resolution request fails, anyway, because there is no record for its 
hostname in the DNS tree.)


/etc/hosts, on D7Server, contains a record for D7Server:
192.168.3.31D7Serverd7serverD7Server.inetd7server.inet

Despite the entry in hosts file, D7Server keeps asking the DNS 
resolver to lookup D7Server (the request is logged on the DNS resolver 
machine), instead of reading it from its hosts file.


Do I need to do something more to enable names to be looked up in 
/etc/hosts?

Re: Should hostname always be lower case?

[Martin G. McCormick]

The domain name system is totally case-insensitive so
FiReFlY.HardknocKs.cOm will lookup as firefly.hardknocks.com. I
have been administering the domain name servers for the
okstate.edu domain since around 1992. We use dynamic DHCP name
registration and the names that folks register are loaded with
mixed-case names or names that are all upper case. The only time
it matters is when we are trouble-shooting a problem and someone
is looking for a certain name in a zone transfer and the name
they are looking for is stored with upper or mixed case. The
person working on the zone transfer must always remember to do
something like a grep -i so that they don't miss the right name
but in a different case than was expected.

Well there's the pcspkr module; you must unmute the appropriate channel
in the mixer of your choice to hear the beep through your speakers (or
headphones).

The rest of your article is beyond my comprehension, so perhaps my reply

If you run alsamixer, the pc-speaker settings can be unmuted to
duplicate the beeps sent to the onboard speaker.  If you have more

When did this dependency change occur?  I installed Wheezy in Feb or
Mar 2013 when it was still Testing.  It became Stable in May of that
year.  The Installer chose the Nouveau driver for my nVidia graphic
card.  Sometime later (several months) I replaced it with the
proprietary nVidia driver.  About Oct or Nov, someone did a similar
install using my notes, and didn't have any problems.

That's good.

Anyway, a fabrication defect could happen for a new drive and an old
drive. Electrostatics or aging of the materials unlikely is an issue.
Assumed the shelf was in an unheated room somewhere in Siberia, this
likely could damage the drive, but assumed it was on a shelf, in a
"normal" house, on some place on this planet, with moderate
environmental conditions, 2 years are nothing.

Martin,

I'm not aware of a module - but there are a lot I don't know about, 
anyway.  Just one note - it's the transducer which actually generates 
the sound; it's being fed with a DC voltage.  Connecting headphones to 
this will only give you a click in the headphones (and probably blow the 
board due to the low impedance of the headphones).


IOW, don't even THINK of doing it :)

Re: I need to hear PC Speaker Beeps through the Audio Output.

[apflewis]

Other than what you described, I doubt it. The on board speaker is used for 
bios level error codes. That is, identifying error conditions that exist before 
higher level hardware (including your sound card) has been initialised during 
the O/S boot.

Because the drives are very silent, we don't hear them. I don't
remember, but I guess I noticed it, because the external drive was on
the table and the drive's LED stressed me.

Now that I read it, I remember the name too :D.

Assumed the drive is behind an USB controller and there should be no way
to open the case, then, when using GNOME, MATE, XFCE, replacing GVFS by
a dummy package could help. But it doesn't help always, from time to
time some other software wakes up the sleeping drive.

Yeps.  I wasn't aware of the problem until Ralf spoke of it here (and my

I used the idle3ctl tool and turned the "feature" off completely (but this

I can't turn it off (USB controller + case that can't be opened), so
every 30 minutes when the drive want's to sleep, the drive gets touches
by gvfs and similar software and get a wake up call, so its spinning
down and up every 30 minutes. I installed a dummy package for gvfs, but
sometimes, e.g. after using K3b, something else behaves as gvfs would
do.

Some drives spin down and up every 8 seconds, but assumed you have
"direct" access e.g. by SATA, instead of an USB controller to SATA, you
likely can change the settings.

There is proprietary software to change the settings and Linux software
that can do it. I didn't find it, but it is (at least was) mentioned by
an Arch Wiki.

No. :-(

But I do have some thoughts.

First, if you're not unmounting /srv/backup as root, try doing so.

Next, before /dev/mapper/backup-decrypted can exist, something
(cryptsetup luksOpen) must create it. Look for that, in /etc/fstab and
elsewhere.

Also, something somewhere must input the LUKS filesystem's password.

As a reference, here's my shellscript for mounting an encrypted Blu-Ray:

==
#!/bin/bash

discdev=/dev/sr0   #change as needed for system
udfmountpoint=/mnt/test
mapperdev=udf

udfloop=`sudo losetup -f`

sudo losetup $udfloop $discdev
sudo cryptsetup luksOpen $udfloop $mapperdev
sudo mount /dev/mapper/$mapperdev $udfmountpoint
echo Encrypted loop device is at /dev/mapper/$mapperdev or $udfloop.
echo Read files from $udfmountpoint
==

When ready to unmount the disc, I work backwards, all as root or using
sudo:

* Unmount the disc from the mapper device.
* Eject the disc.
* use cryptsetup luksClose to close the encrypted device.
* Use losetup -d to delete the loopback device.

I don't know about eight seconds as a specific value, but the last
time I put a WD Green drive into a server (and, btw, it is the last
time I ever will), it wasn't the drive that got old, so much as
listening to the complaints of my users: the first time they hit that
particular server after a period of idleness, stuff would take
*forever* to load up. Of the order of ten seconds just waiting for the
disk to spin up, worse in some cases. (Possibly exacerbated by human
beings with low timeouts, who would cancel the request and start a new
one - resulting in a backlog of requests once the drive finally got
going. But still, it was quite a delay.)

I have a WD green disk (3GB, IIRC) in my backup server. Could you please
elaborate on the steps, and in what ways it gets old quickly?

This is actually pretty important because all my backup data is stored
there.

What exactly do you want to do after connecting the phone to your
computer? Access files on the phone from your computer? USB mass storage
is a little out of fashion, unfortunately. You need some sort of MTP
(Media Transfer Protocol) in your file manager. Gnome supports MTP using
GVFS. KDE apparently needs kio-mtp:

https://wiki.archlinux.org/index.php/MTP#KDE_MTP_KIO_Slave
https://packages.debian.org/search?keywords=kio%20mtp&searchon=names&suite=all§ion=all

Looks like it is only available in testing. People who use KDE might
know a better answer than using nautilus (or thunar).

still running.

I've had that model connect fine to a Wheezy with backports KDE.
dpkg --get-selections | grep mtp
kio-mtp install
libmtp-common   install
libmtp-runtime  install
libmtp9:i386install
mtp-tools   install


I might have to dig through my notes as I have a vague feeling kio-mtp
wasn't straight-forward. I also upgraded my udev rules for android - not
sure if it's necessary for that model.


Kind regards

That said, some newer Android versions/devices do not use USB Mass
Storage for mounting but instead use MTP. That will probably require
extra libraries/programs to be installed.

Google tells me this is an Android device. Are you trying to mount the
phone's FS? If so, I believe an option on the phone will trigger
mounting as a "mass-storage device".

mount inconsistencies

[Jochen Spieker]

Hi folks,

this looks very weird to me. My wheezy system claims that a filesystem
is mounted, but the mount directory appears to be empty and umount fails
because the filesystems is not mounted, after all:

| # grep backup /etc/fstab
| /dev/mapper/backup-decrypted  /srv/backup  ext4  
noatime,nodiratime,barrier=1,noauto,nodelalloc  0 0
| 
| # mount | grep backup
| /dev/mapper/backup-decrypted on /srv/backup type ext4 
(rw,noatime,nodiratime,nodelalloc,data=ordered)
| 
| # df -h /srv/backup/
| FilesystemSize  Used Avail Use% Mounted on
| /dev/mapper/backup-decrypted  2.5T  1.8T  699G  72% /srv/backup
| 
| # ls -la /srv/backup/
| total 8
| drwxr-xr-x  2 root root 4096 Oct 21  2011 ./
| drwxr-xr-x 11 root root 4096 Oct 22  2013 ../
| 
| # umount /srv/backup
| umount: /srv/backup: not mounted

I don't think it's important, but the filesystem is encrypted using LUKS
on top of an LVM volume:

| # grep backup /etc/crypttab
| backup-decrypted/dev/mapper/backup2-lvol0   none  
  noauto,luks,cipher=aes-cbc-plain:sha256

Interestingly, when I mount /srv/backup again, I can see its contents
and umount it afterwards. But only once. Complete transcript:

| # mount /srv/backup/
| 
| # ls /srv/backup/
| abattoir/  abattoir-winxp/  cupcake/  jigsaw/  lost+found/  mail/  manowar/  
_manual/  xenhost/

(rw,noatime,nodiratime,nodelalloc,data=ordered)
| 
| # umount /srv/backup
| 
| # umount /srv/backup
| umount: /srv/backup: not mounted

Do you have any ideas what's wrong?

The fact that a mountpoint can be mis-interpreted by the system for
the root of a directory sub-tree on the parent disk has been around,
as a gotcha, pretty much from the beginning of Unix. 'mountpoint' is
also the name of a test program that allows a sysadmin to test for
this situation. Too much name space overloading here, IMHO, but I
can't make a good suggestion as to what to do about it ;-)

Re: Sony Xperia Z1 USB

Tried 'dmesg' and this is what I got that is relevant to the phone:

Sony Xperia Z1 USB

[Edvin Hultberg]

Hello there! First time interacting with this mailing list.

I recently tried connecting my Sony Xperia Z1 to my computer by 
USB3/USB2. And it didn't quite work as expected. I recently ditched 
windows in favour of debian 7 with KDE. Is there some sort of debuging 
to see if debian detects the phone or anyone having experienced the 
same problem?

More tech details: debian 7 "wheezy", linux 3.2.0-4-amd64, KDE SC 
Version 4.8.3.

Re: Kernel fails to detect internal hard drives after routine apt-get upgrade

[O]

Hi Stan et al.,

Booting from the working kernel, I have dumped dmesg here:

http://pastebin.com/MBTDfgc4

I tried to save dmesg booting under the 3.2.0-4_amd64 kernel from within
initramfs, to no avail (I cannot mount usb drives to save the information,
and it does not see the network).  However, when I added "debug" to the
kernel line in the boot command, I was at least able to see the system
messages while the errors were happening.  Here is the relevant block of
text, and sas is involved:

ata7: sas eh calling libata port error handler
sas: sas_ata_hard_reset: Unable to reset I T nexus?
sas: sas_ata_hard_reset: Found ATA device
sas: sas_ata_hard_reset: Unable to soft reset
sas: sas_ata_hard_reset: Found ATA device
ata7: reset failed (errno=-11) retrying in 10 secs

Searching the web for "Unable to reset I T nexus" led me to this thread:

http://www.gossamer-threads.com/lists/linux/kernel/1912604

... which was posted a short time ago and appears to be the identical
problem.  However, I am struggling to understand what I should do in
response.  It seems to be saying that my hardware and its drivers are too
"new" for Wheezy, even though this machine is 2 yrs old??   Does this mean
I have to upgrade to Jessie?

Thanks,

O

Here's how to avoid that:

Mount /mnt/backupserver

Make sure your backup system is writing to
/mnt/backupserver/specialcodename/hostname/...

If your backup system can't see the specialcodename directory,
it should not create it, but give an error message instead.
(Test this, and write a wrapper if your backup system
obstinately decides to create intermediate directories for you.)

RFC 1035 ("DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION"), Section
2.3.3 ("Character Case") states "For all parts of the DNS that are part
of the official protocol, all comparisons between character strings 
(e.g., labels, domain names, etc.) are done in a case-insensitive manner".

In other words, D7Server, d7sevrer and d7SeRvEr are all the same host.
If you have software that confirms this (for example, a mail server
might check that the IP reverse-resolves to that name), then it should
cope with D7Server being transformed to d7server.

Whenever I create a directory that is going to be a mountpoint, I immediately
set its immutable attribute to prevent exactly this. Nothing can be
written in an
immutable directory. chattr must be run by root user.

# mkdir mountpoint
# chattr -V +i mountpoint

RFC 952 specifies that:

A "name" (Net, Host, Gateway, or Domain name) is a text string up
   to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
   sign (-), and period (.).  Note that periods are only allowed when
   they serve to delimit components of "domain style names". (See
   RFC-921, "Domain Name System Implementation Schedule", for
   background).  No blank or space characters are permitted as part of a
   name. ** No distinction is made between upper and lower case. **


Therefore any conventional DNS should thread D7Server and d7server
the same.

List,

May I ask whether the 'case' of the hostname is important, in the

We have a server running wheezy, and we named it D7Server (not 
d7server).  Could this matter to any resolver attempting to look up 
D7Server?  (It might matter, for example, if standards allow

"Q: What storage services are currently supported?

A: As of Thunderbird 16, we have


DL for Thunderbird may be the best if you prefer using your own
server instead of relying on 3rd-party providers."


Is this what you server you want - one that's compatible with "DL for
Thunderbird"?

http://www.thregr.org/~wavexx/software/dl/index.html

dl: download ticket service

dl is a file exchange service that allows you to upload any file to a
web server and generate a unique ticket for others to download. The
ticket is automatically expired according to the specified rules, so
that you don't need to keep track or cleanup afterward. dl also allows
you to grant an anonymous, one-time upload for others to send you a
file, without the requirement of account management.

dl is usually installed as a "email attachments replacement" due to its
simplicity (though can be used in other ways).

Requirements

PHP 5.3 or higher.
PHP SQLite module (or another PDO database module).
PHP mbstring module.
PHP OpenSSL module.
Web server access for installation and setup.

Optionals:

PHP 5.4+ or PHP APC/APCu module, for the upload progress-bar.

Good looking instructions on the site for apache/lightpd/nginx (I
haven't set up one of these servers but it looks simple to implement in
Debian).

Your link says:

Last but not least, you can use Filelink with a WebDAV server with the
WebDAV for Filelink add-on.

Therefore, you setup your own WebDAV (stock debian apache2 will do),
install this 'WebDAV for Filelink' gizmo for the Thunderbird, and …
that's all that is needed.

So, what could go wrong with a hard drive in storage? Thermal noise
could flip some bits on the plater, but that's going to be rare and,
with no data on the disk, shouldn't matter a great deal. 

People talk about lubricants evaporating and causing the motor and/or
head to seize, but remember that the drive is designed to run hotter and
harder than it will be in storage.

Magnetic fields or ESD could damage the control circuitry, but if the
drive is still in it's original packaging, then that will protect it
from most of what could happen in transit.

So, in my estimation, a hard drive should be good to go after 10-20
years on the shelf. Beyond that, it may be more hassle finding a
suitable computer to run the drive on than it's worth.

At 2 years old, the drive should still be fresh as it was when bought.

Check that the "tun" module is loaded (lsmod will tell you, modprobe tun

You probably did this at a time when a video driver would have been
pulled in by xserver-xorg-core because it depended on xserver-xorg. This
dependency has gone so there might be a problem getting X running with
these two packages alone.

 xorg-server (2:1.9.4-2) unstable; urgency=low
 .
   * Put an end to the dependency hell! Now that we have proper
 dependencies between drivers and the server, remove xserver-xorg from
 xserver-xorg-core's Depends (Closes: #362313). In a nutshell, one may
 want to choose between installing:
 - xserver-xorg-core: the server itself, with no strings attached.
 - xserver-xorg: pulls the server and drivers, contains the X wrapper
   and some documentation.
 - xorg: pulls xserver-xorg as well as various X11 clients and fonts.

You can tag the files based on the *.cue file like this:

I think the package you need to install for this is cuetools.

Journalism Data Analysis

[Weaver]

Greetings all,

I don't actually see this as being so much of a problem. Does anybody know
of anything specifically customised to purpose as yet?

"academic computer scientists have upped the ante yet again, calling for
the creation of a new field: "computational journalism." They foresee the
development of algorithms that can automatically do much of the data
analysis and pattern recognition now being done manually."

I can't find anything in a packet search.
Thanks for any time and trouble.

Itay

after you had rsync-ed most of the filesystem over to the new disk, did
you then manually create the special mount points you'd left out, like
/proc, /sys ...  ?
