Re: OFF TOPIC - Problemas com mysql

[Gustavo Villela Goulart]

Opá Mauricio, boa noite!

Vc mexeu na conf do mysql?

Por default o path do datadir é: /var/lib/mysql
Seu datadir esta assim: /dbase/mysql

Se vc alterou essa configuração na mão, ou as aplicações que vc esta usando
fizeram essa alteração, é o que esta causando o problema.
Para vc alterar o datadir do mysql, faça assim:
   - Pare o mysql
   - Copie todos os arquivos de /var/lib/mysql para o novo diretório
   - Altere o path  datadir= /dbase/mysql
  - Inicie o mysql

Se vc não fez assim e só copiou os datafiles do bacula e da outra
aplicação, não vai funcionar. Se copiou com o banco funcionando(mysql
startado), provavelmente corrompeu os arquivos.

Espero ter ajudado.

When I first installed Debian 10, I installed Win 10 in a
virtual machine using KVM/QEMU and everything just worked. I
could copy/paste between host and vm and access host disks
in the vm. And zfs file systems worked.

The main problem was that dpkg would kill the system trying
to setup
linux-image-4.19.0-18-amd64.



Mark this SOLVED (partially): software problem.

dpkg continued to kill the system trying to setup
linux-headers. I discovered that dpkg will purge the
linux-headers package and then I can try installing again.
On one try I was running pg on dkms in an attempt to see
what was going on that killed the machine. Two times I got a
long screen full of tasks running various types of cc just
before the crash.


What's "pg"? It doesn't appear to be e.g. a shell builtin ('type pg'
reports 'bash: type: pg: not found'), and I don't find it in the
archive. For example,

$ apt-file search -x /pg$

finds only two results, from the package grass-core, which appear to be
(parts of? related to?) database drivers.


I set up my pg to repeat every few secs and spooled the
output to a file. Then I started a tail on that spool file.
Surprise!! It ran to completion!

Here is my analysis: I have a big system. An AMD 8 core
Ryzen running at 3.8GHz with 64GB of memory. I think that
without any other load on the machine some task is getting
started before it should and either steps on a task that
should have finished by that time or can't find something
that was supposed to be created by a task that hasn't run
yet. It has to be something serious because all the
screens/sessions are cleared and the system is frozen. I
have to use the reset button to re-start and once or twice I
have had to cycle the power to get re-booted.


This doesn't look like a terribly likely scenario to me, but if it *is*
what's happening, that's definitely a bug - though a bug in what is less
than clear.


Sorry, pg = ps

That is the only thing I can think of that it might be. I 
have run dpkg --configure -a or with a specific package name 
and every time the package was linux-image-... or 
linux-headers-... it killed my machine. It happened with 
kernel 4.19.0-18-amd64 and 4.19.0-20-amd64. I ran it a dozen 
or more times with the same results. The two times that I 
caught any output from ps that was useful it was running 
many tasks of cc.

I agree, people should not expect help on 3rd party applications,
frankendebians, or other situations that run against the standard
advice around here. I think you did a good job of explaining this to
Steve.

Once in a while, someone asks for help in such a situation, and someone
else is in a position to give it. But that's the exception. So I have
no problem with someone asking. I do take exception to some twatwaffle
getting irate because no-one answered his badly framed and off-topic
query.

Besides, we're all volunteers here, something some people can't seem to
get wedged between their ears.

OFF TOPIC - Problemas com mysql

[Mauricio Neto]

Amigo boa tarde.

Desculpe o off topic já que se trata de um problema de mysql e não 
Debian mas como nesta comunidade temos conhecedores de tudo relato uma 
situação muito estranha na esperança que algum dos amigos já tenham 
visto algo parecido, ou posam indicar um forum mais apropriado...


Instalei o mysql 8.0, Apache2, PHP7.4, o Moodle (EAD) e o Bacula backup. 
tudo funcionando perfeitamente durante alguns dias e sem que ocorresse 
qualquer evento estranho tenho o seguinte cenário:


As aplicações não encontram os databases.

O  mysql -u root passa a conectar sem senha ou usando a opção -p aceita 
qualquer besteira que eu digite como senha. Originalmente criado com 
senha como sempre o faço e situação verificada quando esquecia ou 
errava  a digitação da senha :-)


No repositório do mysql   (/dbase/mysql) existi os banco de dados moodle 
e bacula como pode ser visto com o ls mas o comando mysql show databases 
não mostra os bancos.


O comando select user   não mostra os usuários moodle e bacula 
criados anteriormente para as respectivas bases de dados e o não aparece 
mais nenhum hash de senha para o root.
Efetuei um teste definindo uma nova senha para o root com o comando 
ALTER  conforme pode ser visto abaixo mas a senha não foi criada...


O repositório do banco de dados (/dbase/mysql) esta usando o filesystem XFS.

Qualquer ajuda sera bem vinda, inclusive a indicação de um forum sobre 
mysql.


Agradecendo a todos,

The USB 2.0 failures occur with and without the KVM switch.


The USB 3.0 correct behavior occurs with and without the KVM switch.



Do you configure the mouse at all, bearing in mind that unplugging
and replugging it may lose that configuration. (I don't know how
KVMs fit into this model.)



Changing pointing device settings via Xfce Applications Menu -> Settings 
-> Mouse and Touchpad does not seem to affect the failures, but I have 
not made many changes.




Always bearing in mind that reporting against Debian 9 might only
result in a stifled yawn.



The same problem exists in Debian 9, 10, and 11.  I can readily file bug

I saw one GUI input event storm in ~6 hours of use following the above

Hi Charles,

Thanks for stepping in with concrete help - it's good that we had someone
else running Signal to help. I think the point I wanted to make is that
we _can't_ be expected to help out on all third party .debs, especially
when that .deb is compiled against an obsolescent version of Ubuntu.
Likewise "I'm running Linux Mint / TDE and I can't find support in their
channel - please help"

A large chunk of the mails here are sorting out:

"I don't know how to edit an /etc/apt/sources.list" or
"I added some app from some site and it all broke" or
"I mixed Ubuntu and Debian and now I don't know what I have"

Those are almost as popular as the favourite:

"I did something, then I did something else then X happened so I did Y
and now it's not working but I've no idea how I got here" 

which is a well known thread starter here.

With every good wish, as ever,

Andy Cater

In general I agree with this. However, this is what the signal folks

As luck would have it, I just had an update for signal (5.40) waiting

Hi steve,

Sorry: This is a third party .deb package which appears to be packaged
for an Ubuntu release 16.04  (Xenial Xerus) that is now out of standard
support from Canonical with effect from the release of Jammy Jellyfish 
yesterday.

I'm not sure we can help you on this list and I would suggest that you
ask signal.org.

Mixing .deb packages from multiple Debian/Debian-derived distributions is
normally a very bad idea - https://wiki.debian.org/DontBreakDebian

This line in ~/.config/openbox/autostart starts firefox without recognition of 
geometry.
(sleep 3s && firefox -geometry 800x600+1000+20 ) &

https://linux.die.net/man/1/firefox doesn't mention geometry but 
suggested this.
(sleep 3s && xterm -e firefox -height 480 -width 640 ) &
Good, that works.

Google and a bit of luck led to this page
http://openbox.org/wiki/Help:Configuration#Applications 
and the link to this. 
http://openbox.org/wiki/Help:Applications

This command with a click on the target window is critical to 
identification of a window.
obxprop | grep "^_OB_APP"

This stanza puts the firefox window at the upper left of the right 
screen.

   1300 0 


A window with these properties 
_OB_APP_GROUP_CLASS(UTF8_STRING) = 
_OB_APP_GROUP_NAME(UTF8_STRING) = 
_OB_APP_CLASS(UTF8_STRING) = 
_OB_APP_NAME(UTF8_STRING) = 
_OB_APP_ROLE(UTF8_STRING) = 
stumped me until recognizing that this stanza provides a default 
(matches any window) case.

   10 10 


For now this is the complete applications stanza in 
/home/me/.config/openbox/rc.xml.


# Default window location at the upper left of display coordinates.

   10 10 



   1300 0 




There might be a way to include window height and width in rc.xml but 
I'm content to leave them in /home/me/.config/openbox/autostart for 
now.

Here display :0 spans the two screens.  One display coordinate system 
can be used directly as above.

There are two kinds of VNC servers.

The first kind runs a VNC session which is totally independent of what's
running on the physical display (if anything).

The second kind runs inside an existing X11 session, and replicates that
X11 session as a VNC session.  I only know of *one* VNC server which does
this, and its name is "x11vnc".

> Does the VNC depend on the DE having been launched first?

Only the second kind (x11vnc) does.

> Or do I have to launch the DE from the VNC’s xstartup file?

For everything else, yeah.  That's how it would normally be done.

With most VNC servers, you get a command called "vncserver" which is a
symlink to whatever the real command is.  And to start a VNC session as
yourself, you would login, and then run something like:

  vncserver :1

This would attempt to start a VNC session on the :1 display.  Obviously,
if something is already using :1 this will fail.  You'd need to use :2
or whatever, in that case.

Each VNC session is accessible by a separate TCP port, which is some
constant plus the display number.  The VNC client software should give
you some way to select which port/session you want to connect to,
usually with :1 or :2 or whatever display number as the indicator.

For more details, see the documentation for whichever VNC server package
you choose to try.

Oh, one last thing: you may not want to run a full-blown desktop
environment as your VNC session.  I mean, you *can*, but it's probably
overkill, and some of the fancy features may not work right.  You
may want to install a traditional window manager and use that for your
VNC session(s) instead.  But it's totally up to you, as we don't know
what your specific needs are.

(I've got some end users at work who use VNC sessions for working from
home on a specific task.  I installed fvwm and configured a basic menu
and a VNC session startup script for them to use.  They all adapted to
it quite well.)

Hello David(s)

Bearing in mind that LTS support for Debian 9 Stretch ends in approximately
two months (2022-06-30), I'd suggest that a bug report there will probably 
not attract significant attention, though there is likely to be a final
point release as it goes out of LTS.

I would advise anybody running Debian 9 now to consider moving forwards to
10 or 11. Debian 10's EOL for stable support before transition to LTS is 
approximately 2022-08 - https://wiki.debian.org/DebianReleases

If it's a bug on 9/10/11 and there's a KVM involved - it's likely to be 
the KVM in all honesty - I have similar problems with a KVM not recognising
a trackball until it's unplugged/replugged. USB 2.0 for that one.

All the very best, as ever,

Audacity parameter 'phase_shift' out of range [0 - 30]

[davenull]

Hello,

While trying to debug Audacity

- too much background noise
- unusable preferences menus on GTK DE (LXDE) with dark theme, even with 
dark theme from audacity menu.


I launched it from the terminal too see if there is any error and I got 
this error


[AVAudioResampleContext @ 0x55c8497eb4c0] Value 160.00 for parameter 
'phase_shift' out of range [0 - 30]


That certainly haven't anything to do with the broken dark-theme 
(partial dark theme, with grey text on white background in the options 
names in prefs), and probably nothing to do with background noise. But 
I still want to correct that parameter, so I least I don't have another 
broken option/parameter to worry about and I could focus on the initial 
problems. The problem is I'm not familiar with Audacity at all, so 
I have no idea how/where to change this menus.


I don't use Audacity often, chances than I have forced any parameter out 
of range is pretty, but still, I thought maybe I did, so I deleted 
audacity.cfg file so Audacity recreates the default config, but doesn't 
correct that error so it probably the default config from Debian 
package. At least on Debian old stable. I don't have time for full 
upgrade at the moment, though I should do it as soon as possible. But 
I'm still not even even sure it will correct the described problems. 
Until I can do the fill upgrade, I'd still like to correct the 
'phase_shift' parameter value. Does anyone know where it can be done ? 
Doesn't look like that 160.00 value stored in a text-file because 
ag_silversearcher (like grep but better) didn't find anything on my 
homedir for "phase_shift". And of course, I looked for audacity 
parameters in /etc but I found nothing.


I'd like to either find where is "phase_shift" stored so I can modify 
it, or to know where (audacity.cfg in homedir?)) and how (syntax) to 
override it. OR doen it come from another software than audacity itself 
? (audio server) ?


PS : Not to mention the spyware "telemetry" in the newer versions, v3.x 
I think ?. I wanted to tried Tenacity but not packaged for Debian, but 
I'd rather avoid AppImage stuff (because it is annoying in terms of 
maintenance/security/upgrade management), and it doesn't even start by 
the way, it required some library which isn't included in the Image and 
can't be installed on Debian because of dependency conflict.

Aan Paul van der Vlis. en ev. anderemn?

Beste Paul,

Ik word geconfronteerd met iets waarmee ik nog nooit te maken heb gehad. Een soort drietrapsraket aan beveiligingen voor website 
waarop ik dingen voor de rouwpraktijk van mijn vrouw pleeg te regelen. Inloggen gaat per certificaat: dat is ok.
Vervolgens wordt een pincode plus ww gevraagd. Is ook ok. En dan, dat is (nog) niet ok, een 2FA beveiliging. Volgens mij zijn daar 
libpam module(s) voor nodig waarmee ik geen enkele ervaring heb. De website = VEZOZO (voor zorg en zorgverleners/instellingen). 
Mijn vraag: wil je als je wilt en kunt mij hiermee helpen? Zodat ik als vcanouds die website weer op kan?


Hoop van je te 'horen'

Je buurman,

I will install Debian 11.3 on a fresh partition and have /home remain on

I'm aware of cautions about upgrading in-place  cf 
[https://www.debian.org/releases/bullseye/amd64/release-notes/ch-upgrading.en.html] 



Are there things to be aware of when using the same /home partition on 
both?




Yes. This discussion has pointed out several things I wish I had been 
aware of when I had done the original install.


Debian 11 will be installed on a different physical machine which has 
much more physical disk space and an available SSD slot.


I will use a separate /home partition and take a look at possible 
additional partitions while moving data piecemeal from this machine.


Thanks to all for some education.

M'agradaria de nou revisar «in situ» la configuració de la BIOS, però
encara no he tingut oportunitat d'anar al local on hi ha aquest

Cercant per Internet m'ha coincidit el problema amb altres a qui el

és a dir, que Linux no detecta CAP processador ni nucli, i aleshores

noapic

acpi=ht
acpi=noirq

Has provat aquests?

Gràcies; provat sense bon resultat.
Encara segueixo amb acpi=off

Aleshores, em pregunto com ho haig de fer per a què l'ordinador es

He trobat que n'hi ha que ho resolgueren actualitzant la BIOS, que
és el

Aquí n'hi ha que comenten, sota un problema semblant, que Debian

Desktop environment and VNC

[Julius Hamilton]

Hey,

I am having some difficulty connecting to Debian 11 Bullseye via VNC.

I am trying to understand the situation comprehensively.

There are many VNC servers that can be installed from apt, but you also
need a desktop environment, which can be installed from tasksel.

I see in tasksel that I already have Debian Desktop Environment and GNOME
installed.

I am pretty sure my VNC server is running and fine as it is except a DE is
not running so that’s why I can’t connect.

Is it enough to launch the DE, open a new screen with Screen, then launch
the VNC?

Does the VNC depend on the DE having been launched first?

Or do I have to launch the DE from the VNC’s xstartup file?

One thing I am also struggling with is finding the launch commands for the
DEs I install with tasksel; they don’t seem to correspond to their names.
I.e., I know I installed gnome, but don’t know the command to launch it. Is
there an easy way to scan your system for DE launch commands?

I think “systemctl start gdm3” might do it.

So is the most smooth and straightforward way to get VNC going putting that
in my .vnc/xstartup file? Is that it or is there anything else to be sure
to do?

Thanks very much,
Julius
