Re: Tracing hard Lockup

Java 7 rarely has issues on Java 8 and if they do it's a program error not
system. At this point I'll go back to Jessie or Ubuntu 16.

Thanks for the feedback.

Until I did the fix I mentioned in my original post, that I got from the 
arch forums (fora?), pavucontrol only showed the mono setup as an 
option. The dropdown contained only one option. Ditto the bluetooth 
setup screen you can get to from the place in Gnome where you connect 
the headphones after turning them on.

After I made the fix detailed in my original post, the stereo profile 
became available (specifically ad2p sink profile became available) and 
once available it was used by default.

Perhaps you didn't fully follow my original post -- the question was not 
"how can I fix this?" it was "isn't this fix a bit dodgy; is there a 
better one?" And I suppose now I would add "does anyone know why this 
wasn't an issue in Jessie, which to all outward appearances was 
identical to Stretch in this regard?"

Thanks

I don't think it is that new as I have not done any upgrades recently and I
have
dpkg -l | grep systemd
ii  libpam-systemd:amd64   215-17+deb8u7
  
amd64system and service manager - PAM module
ii  libsystemd0:amd64  215-17+deb8u7
  
amd64systemd utility library

and in the CVE-2017-9445 it says it is fixed in jessie in the above
mentioned versions ... so it must be at least few weeks old as I recently
updated back then.

Another option, set this in kdmrc:

UseTheme=false

SDDM doesn't work for me. It lacks KDM features I depend on. I like the built-in
KDM "theme" look and functionality.

If a java program was compiled and designed to run on specific version it
could be that it causes problems on higher version - especially java 1.7 to
1.8 changed a lot in how things are handled.
Did you try with older java version or with the previous one?

I've been using visualvm to banchmark java threading - I'm not sure if it
will help you. You can set some tight limits to your java program and see
where it breaks and create a dump. Enable debugging and garbedge collector
also tight.

As you have a newer kernel, you can set some limits there too - I don't
recall exactly but there was an option to purge each app using higher than
limit memory. how it is done in ESX - no idea  can't you run it on
another machine

I don't know. Actually I'm using
MPlayer2 2.0-728-g2c378c7-4+b1 (C) 2000-2012 MPlayer Team
which is a real package.

But the thrust of my post was two-fold: (1) get configuration
files out of the way, and (2) get pulseaudio out of the way.
I'm assuming people can handle reading the man page to adjust
the command line arguments (eg my long options _require_ --ao
and --noconfig to parse correctly; the OP seems to get away
with one hyphen).

Were I using stretch mplayer, I would have posted yesterday,
but the thread seemed to have wandered up blind alleys (group
membership, device aliases, etc) without addressing the error
messages posted (missing sound device files, alsa/sdl errors).

Yes, I've used cdplay on occasions, and it's a lot quieter than
cdda because the disc so slowly comparatively, though I always
use eject rather than cdeject as the latter has given me problems.

Of course, with a laptop, you're at the mercy of the constructor
as to whether the analogue link exists.

Linux sound is complex enough that, once things work well enough,
I prefer not to disturb them, which is why I beg your forbearance.

That seems to be correct.

Yes, don't use systemd-resolved in the first place.  As mentioned in the

the problem is not treated as urgent.

Yes, Curt,

It is similar indeed. Also, by the solution they figured out, (editing
Theme=/usr/share/apps/kdm/themes/oxygen-air) I can see that it is using
"kdm" instead of sddm.

That is the root of the problem. A proper solution is just what I said in
the previous email: install sddm as your default and remove old kdm.

Thanks!

Howdy! CVE-2017-9445 is a remotely exploitable bug in systemd. It was

Is there a preferred way of temporarily mitigating the problem?
Remote exploitation that you can trigger by forcing a program to DNS

with no log information or information what exactly this program is doing
not much can be done.

I've faced some similar issues with wrong or incomplete setups, when wrong

Why would you do that? Write and use script to change one 0/1 in
/etc/apt/apt.conf/20auto-upgrades? Or even 2, in case that you change
both for update and upgrade. Not to mention that those using gnome

Re: Tracing hard Lockup

[Mini Trader]

My last two cents on this are that the vCenter consoles shows the machine
going to 100% CPU.  I've tried even executing the java process with the
nice command to see if this could throttle the CPU.

Whatever it is that this java process is doing is completely throwing the
system into a loop hole on this release which I find very odd.

To be exacting, i only doubted the idea. It got disposed by the report
that a normal user (the desktop starting user ?) can have success.

The hardware is at least not yet proven to be faulty. I am not really
aware whether it was reported that one of the successful CD play attempts
was acoustically flawless. (E.g. by pure Grunge with all its fine nuances.)

Did you try as superuser ?

I have the gutt feeling that user "root" is slowly being moved into
the role of the man who once was indispensible but now is just an
old fart whom the young agile people don't trust to do anything useful.

Curt noticed this message in the original message:

So if the software means that the superuser is not welcome, then this
should be discussed with the software's Debian maintainer or its upstream
developers.

The other messages in the original post
  https://lists.debian.org/debian-user/2017/06/msg01215.html
look like software or system management problems, too.
(But hey, i am no expert with software that causes flamewars whenever
 its name gets mentioned.)

It has been deprecated by MMC-5, which is the first MMC version mentioning
Blu-ray drives. So one could assume that BD drives would not support the
PLAY AUDIO command. Nevertheless, my newest two BD drives announce its
availability by feature 103h. Only my good old LG GGW-H20 does not offer it.
I assume the ASUS and the Optiarc burner have an audio socket at their
backside. The last one i had with front earphone socket was a Lite-On CD

As someone whose use and knowledge of anything other than vlc is
minimal I did this on unstable and got

 Unknown option on command line: --noconfig=all
 Error parsing option on the command line: --noconfig=all
 
> Currently I don't have mplayer installed, only mplayer2.

How relevant is this statement to the issue?

  Package: mplayer2 (3:0.23.0-2) 
  transitional dummy package for mpv

  This is a transitional dummy package to get upgrading systems to
  install the mpv package. It can safely be removed once no other
  package depends on it.

Once Thomas Schmitt had disposed of the idea that mplayer requires a
cable between drive and sound card it comes down to software and not
hardware.

(I use cdplay from the cdtool package quite extensively, especially in
scripts. If the OP had been using cdtool, Curt's cable suggestion would
have very likely been correct as cdtool uses the analogue play method).

I installed mplayer on a machine (which has pulseaudio) yesterday. There
was no problem with playing an audio CD, but I did not go in for any
customisation, which is probably not the case with Rodolfo Medina.

This doesn't sound to me like you're being logged out.  Rather it sounds
like light-locker is locking your screen, which is does by bringing up a
new lightdm instance.  

> The question is still 'where is the auto logoff taking place and where

Please check whether light-locker is running.  If it is, you could
disable it in the list of startup applications.  Or, depending on what
desktop environment you're using, you could try removing the package
entirely.

I realize that this doesn't explain the problem with your printer.
Maybe that's actually a separate, coincidental issue?

Re: Debian v9 and auto logoff

[tony mollica]

FOUND IT!  I think.

And there's a lot of discussion about it, too.
The issue is that Stretch has implemented light-locker as a screen 
locker for security purposes.   A search for 'debian light-locker' 
brings up a lot of discussion and bug reports concerning this new 
standard addition to Stretch.  It's doing what it's supposed to do on my 
system but I got used to mate-screensaver so I'll probably continue. 
For now, I just killed the process to see what happens.  The package 
can't be removed without taking a bunch of other stuff with it, it 
seems, but I'll try removing the startup file in /etc/xdg/autostart in 
an attempt to do it the easy way.  I browsed quickly through the source 
and found some configuration items that I don't quite understand.  Maybe 
a config file is planned for the future.


So, now I know why the system drops back to a lightdm greeter even 
though a screensaver is active.  I think I know how to disable it but 
there's no formal procedure for doing so.  It's tied to xfce packages so 
I'm afraid to remove the package for fear of spending another 3 days 
setting up the system again with all my apps.  But I'm still not sure 
why the running apps were suspended and didn't continue to run in the 
background.

My points were aimed at two sections: "how did this got to stable
without really being advertised properly through those running
testing. I was under the impression that for anything other than
security-bug-fixes everything goes through the unstable and testing
first. This seems as something that appeared behind us."
and
"An update of apt/synaptics/aptitude could have included

Actually, upon further reflection, the root error message from his
original post was:

 XDG_RUNTIME_DIR (/run/user/1000) is not owned by us (uid 0), but by
 uid 1000! (This could e g happen if you try to connect to a non-root
 PulseAudio as a root user, over the native protocol. Don't do that.) 

which might mean the incriminated environment variable is being inherited from 
his
user shell (if he used 'su' maybe).

So, in order obviate that, he should--well, you tell me.

First, it would seem sensible to clean up your first post by
revealing the output from, say,

# mplayer --noconfig=all --ao=alsa cdda://

Currently I don't have mplayer installed, only mplayer2.
I would point out that this command still reads input.conf
files so you might want to move them out of the way too.

Secondly, most of the error messages involved alsa rather
than the CD player. How does root get on with playing
sound files from other sources?

Thirdly, what's in /dev/snd?

There's no need to apologize. As for the root problem I don't believe it
is a problem in the sense you mean it (I think). pulseaudio is not
intended to be run as root (that's what I'm reading on the innertubes). As
usual my understanding of the whole kaboodle is quite fragile, however. Also
I believe pulseaudio is configured per-useredly.  IOW you'd have to
configure it for root in order for it to work (for root). Maybe.

Unless you're not using pulseaudio, in which case...

Now you see who's stupid.

What file system are those disks formatted with?

Things to check:

  - what are the permissions of the files/directories you try to
write to?
  - is the whole disk perhaps mounted read only?

You may get some hints from the error message when you try the
write or from the log files, e.g. /var/log/messages (at mount
time).

Disk Access

[David]

Dear List,

I am using Linux Mint Debian (Betsy) and I'm having problems writing to
removable hard disks.

There are no problems reading and writing to USB sticks.

But removable sata disks I can read, but not write to. These disks are
in caddies that are designed to be removed.

I thought the problem was because one of the disks in question was not
formatted on the Mint machine, so I formatted a new disk, same problem.

Can anybody offer me a solution?

Would I have the same problem if I used native Debian?

Thank you for reading this.

David.

Re: Debian v9 and auto logoff

[tony mollica]

Yet more information on this particular issue.

I let the xscreensaver run overnight and it appears that after some 
time, whatever amount of time that is, the system still falls back to 
the lightdm greeter for logging in.  However, after logging in again I 
now get the xscreensaver unlock input window, so it appears that even 
though it now falls back to the lightdm login it doesn't kill the 
xscreensaver.  Previously the mate-screensaver unlock was evidently 
bypassed when the lightdm greeter was enabled.


The question is still 'where is the auto logoff taking place and where 
is the config for that"?


Next question is 'with no screensavers enabled, how long will it take 
for the system to automatically log me out to the lightdm greeter'?

It does the same thing, locks the screen and does not drop back to the

I'll try and contact the author or package management folks to see if

This bug report sounds familiar but I find no evidence of anything that

The only screensaver loaded is the mate-screensaver.  If I disable the
screensaver via the idle time and lock options and then lock the screen
manually, it stays at the mate-screensaver lock normally and never falls
back to the lightdm logon screen.

Even so, it's odd that if the screensaver idle time and lock options are
chosen,  and the screen is locked after the timeout, or locked manually
then the screensaver activates like it should but after a time it falls
back to the lightdm greeter screen.  BUT, the programs that were running
at the time are not killed but just appear to be suspended so when the
logon takes place the programs start processing again.  I would think
that if the system drops back to the lightdm greeter that it would kill
all the processes for the user but that doesn't happen.

I can't find the documentation for the mate-screensaver configuration
anywhere.

Hello, yet again, and dropping the html.

Here's the problem.  I use this computer, previously v8, now v9, for
3D printing.  The old system worked perfectly in that the
screensaver did it's job BUT kept me logged in forever.  The new
system doesn't do this.  The screensaver set off and after some
period of time I get logged off automatically.  The BIG problem is
that when this happens printing stops but the extruder and build
plate stay at operating temperature, which is good to restart but
not good if I'm not there to catch it.  Basically, if I can't
prevent the auto logout this system is useless for 3D printing.

How do I do it, disable the auto logoff?  Searched a lot yesterday
but none of that appears to be in effect here.


Difficult to say. Your desktop environment is Gnome? After such a
forced logout, can you spot anything in the X server log (typically
in your home directory, somewhere in .local/share/xorg, unless you
have an uncommon setup, and then you would know ;-)

Perhaps in /var/log/daemon.log?

Here is an old bug where a crashing screensaver would force an X
server restart:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=569933

Any similarities?

Does it happen when you disable the lock screen feature in the
screen saver? When you disable the screen saver altogether?

Hope there's a useful hint in there.

These two rules do not have the same purpose at all.

The OP's rule applies to incoming SMTP connections forwarded to the server,
in order to workaround the routing flaw (wrong gateway).

Your rule applies to outgoing connexions from the server,

so 1) is useless for incoming connections


That's my point, i misread his rule and thought it was the one I posted.

and 2) would be ignored in the original setup because the server did not
use the router as its default gateway.


Yep, but not if the source ip was being changed to the one of the router in
which case the reply would not go to the dgw.

Tracing hard Lockup

[Mini Trader]

I've installed Debian 9/Stetch and am having issues with what looks to be a
java application.

When connecting to the app from certain devices the entire system will
lockup inside an ESXi VM.

There doesn't appear to be any errors.  The system just locks up, no
console, no IP nothing works. The ESXi host is good as it runs everything
else fine and has so for a long time.

Additionally, I've run this application on other systems (kernel 4.4/ubuntu
16 LTS) and have no issues at all.  How can I track this down?  Nothing is
in syslog or kernlog.

Thanks!

Problem reserving enough space for Java object heap since stretch upgrade

[Adam Rosi-Kessel]

I have been unable to execute Java with >=2048M memory allocation since 
upgrading to stretch. I've changed nothing in my configuration otherwise.


I have plenty of RAM:

# free
  totalusedfree  shared buff/cache   
available

Mem:5168396 3326140  245712 85320 1596544 1227812

# ulimit -v

# java -Xmx2048M

# ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 45 Jun 27 20:45 /etc/alternatives/java -> 
/usr/lib/jvm/java-8-openjdk-i386/jre/bin/java


But the same problem occurs when I switch to other Java alternatives. 
(openjdk-8-jre version = 8u131-b11-2).


Interestingly, if I set ulimit -v to something other than 'unlimited' 
but higher than the amount requested for the java process, it works:


# ulimit -v 2097153
# java -Xmx2048M

(no errors)

But shouldn't "unlimited" be higher than any arbitrary value I put 
there? Also, for Java programs that are run as daemons from /etc/init.d, 
I have been unable to figure out how to get the arbitrary ulimit -v 
setting to "stick".


TIA for any suggestions for how to fix or troubleshoot.

For setting up the Laser Jet Pro M12w you still need a windows or mac
with the supplied software. But ones it is set up you can use the
printer under Ubuntu 16.04 by selecting the HP Laserjet Pro CP1025nw
driver which is part of the HPLib package.

Wired and Wireless with Etables

[ray]

I would like to determine how to configure dom0 to use either wireless or wired 
connections automatically depending upon which are available.

I am trying to get Xen4.9 up and Debian 9 on a Toshiba laptop with only a 
wireless and a wired (enx0) connection through a docking station.  I am trying 
to use:  
https://wiki.debian.org/BridgeNetworkConnections#Bridging_with_a_wireless_NIC
This laptop is a personal workstation implementing a variety of vms and OSs. 
Testing wireless internet connection is using JetPack 4G AP and I intend to use 
various public/private wireless APs.  

It seems the way to do this is to bond wlan0 and eth0 as bond0, then build a 
bridge for domus with bond0.  Etables requires the bridge MAC to be defined in 
the rules.  I do not know how to assign a MAC to the bridge since I don't know 
which interface came up.

How can I set up bridging without knowing which interface is up?

Thanks,
Ray

Recently I noticed that mplayer, when playing audio CDs, is always complaining
this way:

 `Audio device got stuck!'

, and sound continuosly `jumps' so becoming unheardable, and I thought it was
the device's hardware fault.  But vlc plays well with no at all that problem.
I wonder about that...  mplayer is very potent and comfortable, that's why I

I had settled the alias: `mplayer = mplayer -demuxer lavf'.  After removing it,
now mplayer works regularly over CDs (apart from the above problem) as a normal
user.  Instead, as root, the problem I started this thread with remains:
mplayer doesn't work...  Not so great a problem, after all.  But isn't it
strange that something user can do root can't...?

This doesn't help.  But, I repeat, mplayer now works and read audio CDs from
normal user.  Only, it continuosly `jumps' and gets stuck.  (I will open a new
thread about that.)

Oui mais attention au suivi dans le temps. A une époque j'avais un scanner
Epson qui fonctionnait parfaitement avec les pilotes proprio Epson jusqu'au
jour où j'ai passé ma debian en 64 bits... Les pilotes proprio 'ayant pas été
suivi il n'y avait pas de pilote 64 bits. J'ai donc du me séparer du scanner.

Côté imprimante ou multifonction je suis fidèle à HP depuis plus de 20 ans et
je n'ai jamais eu de problème de pilote. Si l'imprimante est supportée par
linux au moment de l'achat, elle le reste au fil du temps.

New infrastructure, new apt.

Where you left off run #apt-get -f install and then #dpkg --configure -a
Do that a couple of times and then you can start using the new apt, as 
in #apt update #apt upgrade and then install package 'upgrade-system' 
and run it and use -f install when you have to and dpkg --configure -a 
until done.



Would I have been wise to upgrade it to Jessie first?


Easier for sure, but you would still use the same steps as above.

J'utilise une imprimante Epson, modèle WF (Work Force), encre,
couleur.
Ils existent de nombreux modèles WF, pas chers du tout.

Consommation encre réduite, même en impression standard.

Imprmante parfaitement reconnue grâce aux pilotes Epson,
mais proprio...

Prix des cartouches XL chez Amazon pour modèles WF = 1€ pièce.

Les imprimantes laser sont chers ainsi que les tambours-recharges.

Not quite what you wanted but you can now play an audio CD.

We suppose the CD ROM shows activity (a blinking light) with
'mplayer cdda://' even though there is no sound output.

How do you go on with

  'mplayer -ao alsa cdda:// ?

Vérifier sur la page WEB de CUPS http://localhost:631/admin que
l'imprimante n'est pas arrêtée par CUPS. En effet sa règle par défaut
est de le faire quand l'imprimante est en erreur, même par simple
manque de papier.
Il est préférable de mettre comme règle d'annuler le travail (job) ou
de le réessayer plutôt que d'arrêter l'imprimante ce qui interdit tout
travail ultérieur sauf en redémarrant CUPS.
Voir http://localhost:631/printers/
Cliquer sur le nom de l'imprimante. Boutons Maintenance, Administration,
cliquer Set default options (après avoir rentrer le mot de passe root
ou administrateur.
Cliquer sur Règles et dans Règles d'erreur, choisir ce qui convient
(j'aime bien abort-job).
Confirmer en cliquant sur Set default options.

J'avoue que je ne sais pas pourquoi ce réglage n'agit pas sur toutes les
imprimantes.

Si ça peut aider mais peut-être que ce n'est pas le problème.
Autre piste : ne pas prendre foomatic mais un autre pilote. Jene
connais pas cette imorimante.

Cordialement.

Brother et Lexmark devrait aussi avoir au catalogue des imprimantes
durable et bien supportées par CUPS pour Linux avec un rapport
qualité-prix intéressant surtout chez le premier.

Un exemple :
lftp sftp://utilisat...@exemple.com
Les commandes sont les mêmes que lftp.
man lftp
ou dans lftp : help ou bien help [lacommande]

J'aime lftp car il est très stable sur une connexion et sa commande
mirror est puissante.
