Ah, I see. I rarely check the Debian Wiki because it is almost
abandoned. I have never found something useful there. For an example of
its state of abandonment see this fragment from that page:

“You really should see _Where is the foo package?_ above, but Debian
ships with Iceweasel, a rebranded Firefox.”

But a non-rebranded Firefox package is available in both Debian 8 and
Debian 9 (at least in the later, this is the default browse installed).

Yes, except when nobody deletes the nested quotations (I do when it is
appropriate). Eventually most of the text in the messages becomes quotes.

Also, it is a problem that one loses track of who do the nested (except
the topmost) quotations belong to. Do you have any recommendation about
that?

Right, but here is a note about your wording: The great majority of
people in debian-user are male (judging by the personal names), and
moreover “he” is established as the pronoun in English when the sex is
undetermined. The use of the female pronoun “she” is situations like
this is unjustified.

I had read [2] in the past, but I did not find anything about posting
styles.

-

I already try to use the inline style when appropriate. I will avoid
quoting the previous message at all in the cases where formerly I would
have used top posting. This seems to be the only change necessary to
comply with your suggestions.

Try dropping the "d" with your searches. It's a trick I learned from
lurking. If I can't find something you all write about, I start
chopping the suggestion into pieces. I just found a few files with
"libvirt" instead of "libvirtd", and they're mentioning virtual
machines.

You know what, I just found something with the "libvirtd", too:
libvirt-daemon. Maybe it's not in Stretch? Both were in Buster. :)

Here it is:

https://packages.debian.org/stretch/libvirt-daemon

There's a typo there if someone wants to have at it. The author
apparently wanted to make sure they got that "e" on the right side of
that "a", whichever side that was supposed to be :)

This is a great conversation. I've been wanting to try this, but I
keep forgetting. It's a large pain to keep updated when you've never
used it. We're talking *years* of never used. :D

libvirtd is in libvirt-daemon, which libvirt-daemon-system depends on. I
have those on a Debian 9.1 vm host.

Hi,

Recap. You have two HDDs:

[1] One 160GB with the OS on so '/'.
[2] Second 1TB.

Correct?

Does [2] get mounted as '/home' or are you using it as a extra data drive? How
are you mounting it in '/etc/fstab'?

You can use the command 'df -h' in the terminal to see mount points.

If [1] is the OS drive as you suggest, the VM HDD is on there. Look at the
screenshot. There is a default pool for VM disk images at
'/var/lib/libvirt/images' and that is where you created the 20GB image.

Regards

Phil

I figure it's best to leave such educational posts to someone who does

[Offtopic] GVFS como root

Saludos cordiales a todos.
Tengo una consulta q no esta relacionada directamente com debian y es
acerca de gvfs-mount.

Nevesito montar un sitio ftp y gvfs me va de maravilla cuando lo uso como
usuario normal, sin embargo cuando lo hago con usuario root no me permite
montarlo.

Aqui hay algo similar a lo q me pasa.

http://www.linuxquestions.org/questions/linux-newbie-8/ubuntu-12-04-cronjob-failed-to-mount-ftp-share-using-gvfs-mount-4175504945/

He buscado en google ya dos dias y no doy con la solucion.
De lo q he encontrado de otras personas con mi mismo problema pero montando
un recurso de samba es usar smbclient. Para mi caso no me sirve.

Si alguien sabe o tiene una idea de como solventarlo ae lo agradeceria
mucho.

Maybe you can use a learning e-mail spam filter (e.g.: bogofilter,
sylfilter, or the one built into your MUA – if any). I do not know how
effective the “learning” part is, but maybe it is worth a try.

Both bottom posting and top posting each have their own disadvantages.
Bottom posting requires scrolling past text that may be not needed. Top
posting puts the messages in reverse chronological order, which is not
something bad by itself.

When I explicitly want a quote to reply to a specific parts of a
message, I post after the parts, as in this message; I don't know if
that would still be considered bottom posting. When I am including the
previous message *only* for reference, I use top posting because the
previous message is also archived in the inbox of the other users, so
the quotation included for reference is of secondary importance, and
therefore IMO should go after the *important* (new) information, that
is, at the bottom.

Is there a rule, guideline or de-facto standard mandating either style
in debian-user?

I usually bounce those messages to report-lists...@lists.debian.org, as
detailed in [1], in the hopes to benefit the other folks here.

Debian's spam filters already do a lot, typically blocking 4 messages
per day, according to [2].

If you feel brave, you may propose SpamAssassin rules, see [1]

The general convention here is to only quote the relevant parts you
are replying to. For long threads this tends to work better.

Worst is, of course, mixing styles :-)

But in general, folks here tend to be tolerant. And yes, there's a
wiki entry encouraging "in-line" quoting [1].

That's why you shoulnd't include the whole message, but snip the
relevant parts you are answering to. Believe me, for long threads,
this tends to work best.

Yes, exactly. If someone needs the unabridged original post, it's either

I do use bogofilter in CM, but since these spam messages all have foreign
(to me) language Subject headers, I can simply enter some relevant words
into a regex, and delete the messages on the server.  I never download
them that way.

Re: What tool can I use to make efficient incremental backups?

Thanks for your answer.

Let me know if I understood your approach correctly. You have a
directory in a btrfs filesystem that is the target of your backups. When
you make a backup, you take a brtfs snapshot of this directory and
*then* use rsync. Is this correct?

Is this a multiboot with Windows installation? If yes, is the problem similar
booted to Windows? If yes, complain to Dell about the display, and be sure to
not mention Linux.

Is the display also a Dell?

Is the display one with GUI BIO/firmware setup rather than good old fashioned
80x25 text?

One of my Dell displays has similar trouble: if connected via conventional
DisplayPort cable, it must be powered up before powering up PC for display sleep
to function correctly. It also has MiniDisplayPort, VGA, HDMI and DVI-D ports
that worth normally. Searching the web I found this and similar problems are not
rare.

Re: kvm/qemu virtual machine can't find hard drives

[Mario Castelán Castro]

Have you passed the appropriate options to QEMU? You *must* use “-drive
file=...”. For example “-drive file=/dev/sda”. Read the QEMU manual for
details. QEMU does not gives the the guest is access to host devices by
default; that would be a very high security risk.

What tool can I use to make efficient incremental backups?

[Mario Castelán Castro]

Hello.

Currently I use rsync to make the backups of my personal data, including
some manually selected important files of system configuration. I keep
old backups to be more safe from the scenario where I have deleted
something important, I make a backup, and I only notice the deletion
afterwards.

Each backup snapshot is stored in its own directory. There is much
redundancy between subsequent backups. I use the option "--link-dest" to
make hard links and thus save space for files that are *identical* to an
already-existing file in the backup repository. but this is still
inefficient. Any change to a file, even to its metadata (permission,
modification time, etc.), will result in the file being saved at whole,
instead of a delta.

Can you suggest a more efficient alternative?

I know about bup  but I have not used it
because it warns that “This is a very early version. Therefore it will
most probably not work for you, but we don't know why. It is also
missing some probably-critical features.”.

I also know about obnam. Unfortunately, the main author it has been
announced that it will be unmaintained because it has become a piece of
engineering, with all the ugly consequences of that, and real
engineering is “not fun” for him.

Thanks.

No, it is the other way around: we rsync the data to a directory stored
on a btrfs filesystem, and then we make a snapshot of that directory.
With btrfs's CoW, only the parts of the files that have changed use
space.

Hum, I think it requires the --inplace option.

We used a similar setup on a server, using the rsnapshot script. But we
have users with huge mbox files that were copied entirely each time. We
changed for a setup with normal rsync (no --link-dest) and btrfs
snapshots, it increased the efficiency (storage and disk bandwidth)
dramatically.

Re: Nommage partitions + grub

Usually the qemu vm runs from a file (created by qemu-img) set up as a disk
drive by qemu.  I use Virtual Machine Manager (along with libvirtd) which can do
all the hard stuff for you.  I usually make my own virtual drive files with
qemu-img and let Virtual Machine Manager control access to them.  libvirtd does
a good job of letting you run qemu from your user account and access the
necessary resources on the host machine.  libvirtd sets up all the network
devices and bridges needed to access the real world. Virtual Machine Manager can
connect to USB devices on the host machine, manage CD drive access (either to
hardware cd drive or iso images ... like an install image), boot devices
(usually the sda drive or cd drive), the amount of memory for each vm and
additional drive you may want (like to try multi disk raid).   Virtual Machine
Manager opens up a vnc (or spice) window where you can see the output from the
vm when it is running on your kde desktop .. either text mode or graphical
mode.  I have about 15 vm's defined.  One runs debian with kde to handle my
weather station.  Another runs win 10 (ug) so I can do my taxes.  Most of the
others are debian and kde testing and unstable installs that I use to test
updates before I commit them to my host desktop machine.

Most debian installs work easily with a 20 or 20 GB virtual drive.  You create
the file necessary with a command like this:

qemu-img create -f qcow2 /home/img/Mymachine/drive.img 30G

This assumes that /home is mounted on your 1TB drive.  Looks like the packages
to get you started are libvirt-daemon-system and virt-manager.

Hope this helps.

Unfortunately I can't seem to use the extra space. After the array

As you can see, there is a discrepancy between the device size (18.2T)

cat /proc/mdstat confirms that the device has all the drives running:

Neither fdisk nor gdisk let me create a partition larger than the 
existing one. Nor do they let me create a new partition anywhere except 
in the first 2047 sectors.


I tried commenting out the mount lines in /etc/fstab and rebooting to 
rescue mode but that didn't help.


I finally tried gparted and it immediately noticed the problem and 
offered to fix it. It "found" the free space at the end of the device 
and I was able to resize the existing partition to fill it. I'm now 
using the full array size!


I'm not sure what the problem is that gparted was able to see but fdisk 
and gdisk couldn't and whether this is a bug in mdadm or something else, 
but I thought I should report it somewhere.


I would suggest you boot to a gparted live disc, so none of your 
partitions are mounted and I will just work better.

Can you explain steps you used to get to that error message? Think that
you've messed something up in installation process, because installer on
virtual machine should not care about your physical drives, it uses
virtual drives that you've assigned to it. In case that you would like
easy to use install process for qemu-kvm, I would suggest you to install
virt-manager, that is GUI frontend for managing virtual machines.

Monitor won't come back from power-saving sleep

[Kynn Jones]

I just installed Debian on a (legacy) Optiplex 9010 desktop, and I'm
working through some kinks.

The most serious one, by far, is that the monitor won't wake up after it
goes goes dark to save power.

Curiously enough, the problem occurs only when X11 is running; otherwise,
hitting the shift key on the keyboard brings the monitor right back.

I have tweaked the BIOS settings to enable waking the computer from sleep
through USB-connected devices, and also wake-on-lan and wake-on-wlan.

How can I troubleshoot this problem further?

Re: How to get around ntpd catch-22?

[Mario Castelán Castro]

Dear sir, unfortunately I do not have a solution to your problem, but I
want to note that in “Failed to start ntpd.service: Unit nptd.service
not found.” the name of ntpd was spelled “nptd”; maybe that is the
source of the problem.

It does not appear to me that ntp is preventing the network from
restarting, because I see a line “-- The start-up result is done.”.
Though I can easily be wrong, as I am no expert in systemd.

However, if the ntp package is really causing a problem, and
reinstalling is not possible, the obvious solution would be to remove
it, and install it again if required after Internet connection is
established.

I use chrony instead of ntp. It appears to be better documented,
designed and maintained.

Regards.

kvm/qemu virtual machine can't find hard drives

[Gary Roach]

Hi all,

Debian 9 (Stretch) system
KDE Desktop
MSI970A-G43 motherboard
AMD FX 4350 processor - not overclocked

Ive been trying to get a virtual machine set up and have run into 
problems with both virtualbox and kvm/qemu packages. I have a very messy 
project (Elmer fem) and want things completely walled off from my 
regular system. So I opted for a virtual machine.


The kvm/qemu package seems to install properly (no errors). But when I 
try to install Debian 9 into it, the installer can't find my two hard 
drives sda and sdb. It then ask me to pick from a long list of drivers. 
I haven't been able to determine what the drivers should be for my 
system.  Sda is boot drive, 500 Gb WD160 and the there is a WD10 1 Tb, 
ext4 blank drive. Both drives show up on Dolphin so they must be mounted.


Am I missing some library or something? Any help will be greatly 
appreciated.


Gary R.

I installed Debian on a (legacy) Optiplex 9010 desktop, using a minimal USB
installation image, and netinst.  IOW, most of the contents of this
installation came in through the network (which rules out the most serious
hardware issues).

One day later, the network connection suddenly stopped working, at all.
For example, the response to `ping 8.8.8.8` is now `connect: Network is
unreachable`.

The problem is with the computer not with the jack, because if I plug a
different computer to the same jack the connection works fine.

I did not touch any network-related config files, so I can't begin to guess
what could have caused this sudden failure.

If I run `/etc/init.d/networking restart`, the output just says `Restarting
networking (via systemctl): networking.service`.  At the end of this
message I post the relevant lines from the output I get if I then run
`journalctl -xe` immediately after.

One can see that the restart of the network is failing due to an ntpd
problem.

If I attempt to restart ntpd, I get the error "Failed to start
ntpd.service: Unit nptd.service not found."

This makes no sense to me: ntpd was clearly available and working for
several hours before this sudden failure.  The package is definitely
installed, and the error above persists even after I run `dpkg-reconfigure
-p low ntp` (which requires no input from me).

The only fix I can think of at this point would be to reinstall ntp
altogether, but I can't do this without an internet connection, so I have a
Catch-22 situation.

How can I fix this problem without having an internet connection?

Have you tried:

It appears that the problem was a network misconfiguration (outside of my

In fact, they are both wrong, at least in stretch.

The service is spelled "ntp.service".  There is not currently a systemd
unit file for it; it's using the init.d script named "ntp" instead.

Beyond that, I have no idea what caused the OP's problem.

phpmyadmin e mysql/mariadb

[Fred Maranhão]

ao fazer um apt-get upgrade, o phpmyadmin foi atualizado.

mas deu pau no esquema do banco de dados.

tem uma opção para ignorar. ignorei o o apt-get upgrade terminou.

agora fiz um apt-get purge phpmyadmin e deu esta mensagem:

  │ Um erro ocorreu durante a remoção do banco de dados:
  │
  │ mysqldump: Couldn't execute 'SHOW FUNCTION STATUS WHERE Db =
'phpmyadmin'': Cannot
  │ load from mysql.proc. The table is probably corrupted (1728)


outra coisa. fui dar uma olhada no mysql, deu um

mysql -u root -p

e quando entrou, o mysql virou um mariaDB sem eu perceber:

# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 9
Server version: 10.1.23-MariaDB-9+deb9u1 Debian 9.0

Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.


será que esqueceram de avisar o mantenedor do phpmyadmin que agora é
mariaDB e não mais mysql?

parece que cada vez que rodo o apt-get cria um backup:

# ls -lt /var/cache/dbconfig-common/backups/*

Problem is that the key is trusted, so I guess the warning comes from 
something else but I don't know why. I'd like to understand from where 
it comes and how to kill this warning (triggers apt warnings in 
monitoring system).


As far as I can tell, that message isn't saying that the key is 
untrusted, but rather that the message isn't (correctly) signed by a 
known key. The error is saying that the signature is invalid. If the 
signature (or the data) were corrupted during download, then that would 
invalidate the signature. If the signature was created using a key that 
you don't have, then that would invalidate the signature (perhaps the 
upstream has rotated to a new key?)


Also, rather than saying "trusted=yes", I believe that a more secure 
method is as follows:


1. Fetch the key from the upstream source.
2. If necessary, run "gpg --dearmour < upstream.asc > upstream.gpg"
3. Move upstream.gpg into /etc/apt/trusted.gpg.d
4. Alter your apt line to read "deb [..., 
signed-by=/etc/apt/trusted.gpg.d/upstream.gpg] http://...;


The theory behind this is that ONLY the repository associated with that 
key can be signed by that key. If you add the key to the main keyring, 
then there is a possibility that they key could be used to 
(freadulently) sign the main repository and you'd trust it.




Thanks in advance,

I've never tried that.  The sox mail list is a good place to ask for sox
help.

One thing I'd suggest (since sox is potentially complicated) is that
instead
of trying to use sox with one command that does everything, you try to
do 
it in stages.  That way you can check that what you get at the end of
each
stage is what you expect.   Sox has effects that will tell you about
what is in 
a file.

 I think first I'd check simply that I could create a file containing
 all three 
channels, eg by: 

 sox -V2 --no-clobber -M piano.wav voice.wav threech.wav  

The -V2 sets a fairly high level of verbosity; you might need -V3
 
The --no-clobber prevents sox from overwriting a file.  It's easy to get
a command
wrong and accidentally destroy an original file; personally I work on
copies of files
AND use --no-clobber.

-M tells sox to merge the files.  You should end up with a 3 channel
file, with the piano
audio on channels 1 and 2 and voice on 3.


If that works (and ironically, Audacity might be an easy way to make
sure) I think 
I'd next try to make a file with the voice channel offset from the
others, perhaps 
by  (guessing again!):

 sox -V2 --no-clobber threech.wav delay 0 0 2t voicedelayed.wav 

For an experiment, it's worth making the delay substantial, for example
the two 
second value (2t) here.  It'll be easy to tell if that worked.  Later
you can try different
values to get the audio aligned where you need it to be.

(Also note that there's an effect named 'silence' that can be used to
chop unwanted
'silent' or at least quieter than the wanted sound audio out of a track,
so a different 
approach that might help would be to make sure that none of the tracks
have much 
silence at the start, before you merge them.) 

Note that so far, none of the three channels have had their relative
volumes changed.

To do that, and create a stereo file from the three, you'd need to use
the  remix  effect.

Your current solution is the cheapest I can think of, and no doubt
you'll learn quite a
lot doing this.  I'm afraid I've no idea about what's currently
available in cheap audio 
interfaces.  Reading buyer reviews in eg Amazon is a good way of finding
out what can 
and cannot be done with equipment though.

More expensive interfaces will be sold on the assumption that people
using them are
using higher quality equipment, eg decent microphones.  As price and
quality of mics
increase you expect to get things like: mics that add little (or barely
audible) noise to a 
recording; mics that are more accurate, mics that can better cope with
both quiet and 
loud sounds...

Such mics though typically need 'phantom power'.  They'd probably be on
'balanced' 
audio cables (so 2 wires plus earth/screen per mic), and possibly XLR
connectors...  
There comes a point where the box you plug the mics into needs to be
designed for 
that.

Then, the signal that comes from a mic is (especially with very
sensitive mics) very 
small.  It needs to be amplified - which is what microphone
pre-amplifiers do.  Cheap
mic pre-amps tend to add noise or ruin the sound from a decent mic... 

After that, the amplified sound from each mic needs to be converted from
an analogue
signal to digital.  Better

Rather than consulting "obsolete & unsecure" documentation you've found

Grub2 won't do anything with menu.lst, unless you explicitly tell it to 
do so with 'legacy_configfile'.


The manual doesn't defined what happens if two passwords are defined for 
the same user, so any of the above options is possible.




  it is just a question about how secure could be a grub password (e.g) if a 
hack (old how-to) is still allowed ... (i suppose
  all vulnerabilities are patched yet).


How is an "outdated & unsecure" howto which defines how to set a 
password "a hack"? Again, setting a password was documented in the 
manual[2] for grub legacy, so following documented procedures is not 
really a "hack".

XFS par exemple, la seule chose que j'ai trouvé à lui reprocher, c'est
la réduction d'une partition, ce qui est extrêmement facile en EXT.

En effet, mais Btrfs n'est pas conseillé pour les données, juste pour le
système, donc une faible taille. XFS est conseillé pour les données
(meilleures performances).

Excellente question, jamais essayé de mon coté ! Mais pareil, il est pas

Thanks...  In fact, what you suggest is exactly what I wanted to do but didn't
manage to...  In fact, suppose I have two files: piano.wav and voice.wav,
created by sox in recording piano and voice respectively, simultaneously.
piano.wav is a stereo file, with the two channels, left and right, inside it;
whereas voice.wav is a monophonic file.  When I put them together to create the
final, say, result.wav, I must properly allign them.  Now, Audacity makes this
job easy thanks to the graphical possibility of seeing the waving forms and
magnifying them.  Instead, with sox, I tried to use the `delay' option with no
success.  Maybe can you suggest a better and proper way to do that...?

One more thing: I remember, Jeremy, your suggestion of purchasing a
multi-channel audio interface, to be preferred to a mixer, and will do in
future.  But do you think that the solution I'm adopting for now: different
files on different single-channel audio cards and then merging them - dou you
think this is a good solution as well...?  What difference between this cheap
one and more or less expensive multi channel interface...?

Thanks,

You do realise that merging files, adjusting balance etc are all
possible with 
sox?  

One reason I do that sort of thing with sox is that by keeping note of
the 
commands I used to do each stage, I automatically document how I 
manipulated a set of audio files.  Documenting anything done via a GUI
as
in Audacity is a great deal more difficult.

It's worth documenting what you do so that if necessary you can exactly 
repeat the process at a later date.
