The directory location may not suit you, but for the short
term you should be able to get the modules you want
installed using root and the cpan client. 

Another way is to use a module called local::lib, 
that let's you have a tree of perl modules in 
an unprivileged directory (by default 
$HOME/perl5). 

It requires setting some environment variables.
Then you need a cpan client that will work with
local::lib. That is cpanm.

So apt-get install liblocal-lib-perl libapp-cpanminus-perl

Setup environment according to `man local::lib`

Then install any module you need with

cpanm Some::Module 

cpanm will respect the environment variable and install
it with all dependencies. You will need to have a
compiler present for building modules with C extensions.

This approach, using an unprivileged directory tree that is
merged with debian perl libraries, will work 
with an upgraded system perl if the modules
are pure perl. Modules with compiled C code
(using perl's XS interface language) will *not* be
compatible with an upgraded binary.

If the locally installed modules are pure perl, they should
be compatible with a newer perl. You will have to determine
if and when you upgrade these modules.

It's possible the same module could be installed in your
local::lib as in the system libraries.  In that case,
libraries will be searched in order specfied by the
$PERL5LIB environment variable. 

FWIW I used to use local::lib, long since prefer to compile my 
own perl interpreters and libraries. Perlbrew and plenv
are tools for managing multiple perl versions.

The issue is that somewhere behind the scenes is a human being, the
Debian package maintainer, who is backporting security fixes (but
not new features!) from newer releases of the module into a Debian
package for a given Debian release.

That's not a mechanical process.

So when proposing to adopt a mechanical process, it's not comparable
to what an actually maintained Debian package is like; it's just a
CPAN module in a convenient format.

Most of the time the upstream author is mindful of backward
compatibility issues and isn't going to release something onto CPAN
that breaks things, but sometimes it's unavoidable and sometimes the
author isn't mindful of this. There is a big variance in quality of
CPAN modules.

So probably the best thing you can do is cpan2deb and stick with
those versions that you have tested, unless an update comes along
with security fixes or features you need.

You can install the package "cpanoutdated" which will tell you about
newer versions on CPAN compared to on your system, though it will
report quite a lot of packaged stuff as being outdated, which is
only to be expected.

Cheers,
Andy

apt has an excellent reputation, I'm not sure I see why mechanizing
such a process as apt does should be necessarily be bad.  I'm not
talking about blind nightly updates.

If this is truely the best way at the moment to keep perl modules
maintainable, I will try it.

Well, that would do the job thoughtlessly. It might backfire
spectacularly.

If one set up a service in that way, it would eventually get a
terrible reputation.

If, on the other hand, one spent the time to maintain those
packages properly... you could be a Debian Maintainer, and get
them into the primary repos.

The third course, that doesn't commit you to doing that work and 
doesn't expose you to that risk, is more or less as I've already

Thanks.  So in one way this makes it easier to remove the module which
cpan doesn't do, but I'd still have to track the module manually and
run this again and again, remembering or scripting something to do all
of this automatically.

Has anyone built something which when you ran apt upgrade, it would
look at each of these packages that were made by cpan2deb, then look
in cpan to see if the module was updated, then create a new deb and
upgrade the package?

That would really automate the whole process like apt upgrade.

cpan2deb takes a CPAN module and builds it as a Debian package.
Use a common suffix like -mgrant and you can spot these in
package listings.

When you upgrade, build new versions of all the -mgrant
packages.

Your simplified statement is invaluable.  "Less is more".

The rather inscrutable section entitled "wpa_supplicant" follows the 
section entitled "WPS" which follows the section entitled "Command 
Line".  The structure of the document certainly doesn't explain the 
relationship of components well. Unhelpful to a novice.  Obvously no 
problem for an expert.  But who should be helped by documentation?

I guess most connections now require authentication.  The explanation 
should be consistent with reality.

My effort to make WiFi work, using network access by a mobile tablet, 
was tough going.  Installation of packages was painful.  I abandoned 
the effort, took the HDD back to a system with wired Ethernet, 
installed LXDE, wicd and dependencies and got WiFI to work.  =8~)

I wonder why the netinstall process in the ISO image doen't include at 
least the base support for WiFi?  Too much data?  Negligence in 
planning the ISO build?

Incidentally, I'd prefer to say that authentication is conducted by 
"authenticator" and "authenticatee".  Meaning is fairly obvious.  
Symmetry is as valuable in technical terminology as in vehicle design.
Yah, I've read https://en.wikipedia.org/wiki/Supplicant_(computer).
Can't help but think that the authors of 802.1X were being a little 
too clever with "authenticator" and "supplicant".  Make it simple as 
possible!

Most maintainable way to install perl modules on Debian sysetms

[Michael Grant]

I try to keep my systems as up to date as possible.  I use apt update 
regularly.  When I can install a perl module from apt, I usually do so because 
then apt update picks up new versions of it.  When I install something which 
has a dependency on a perl module in apt, that module gets installed.  Things 
just work and I am unstressed and happy.

However, what should I do if I need a perl module that someone hasn’t kindly 
created a package for?  I know I can install it from cpan.  But once I do that, 
then I have to keep that module up to date via cpan.  Perhaps I’m not alone and 
someone has a way to cross maintain these things that I’m unaware of?

So I yesterday, I decided to install a perl module from cpan.  I ran cpan for 
the first time in a long time, it asked me some question which I took the 
default (maybe I shouldn’t have!), then I installed Mail::DMARC.  It downloaded 
the source, grinded away for several minutes and when it was finished, it 
successfully installed the module.  Miraculous!

But it installed it in /usr/share/perl/5.30/Mail/DMARC.

I thought that’s odd, why would it install it in a folder that has a perl 
version?  Why not somewhere a bit more general like /usr/share/perl5?

What happens when Perl gets updated and /usr/share/perl/5.30/ is no longer in 
perl’s search path for its modules?  I’m worried that using this DMARC perl 
module, updating perl could just break mail someday!  Shouldn’t the default for 
cpan be something other than this version based directory on Debian?  Should I 
worry about this?  (this may be more a CPAN question than a Debian question to 
be honest).

So my question is, is there a recommended, maintainable way to install perl 
modules on Debian that are not installed by apt-get such that things get 
updated properly?

I suppose this could even be a general question when you consider other things 
like python, php, nodejs  and others, all of which have their own module 
systems.  Feels like there’s a need for a sort of meta-module system that works 
with apt, but I’m not sure which is why I am asking here.

Suggestions and advice welcome!

Setting the volume before running vlc is not an option (see my OP) thus 
it would help using amixer instead of pactl. I'd hit the same wall.

vnc is making my cry

[Thomas Anderson]

I have had vnc working in the past, then as of the past week or so, it
has stopped working.

I have spent many hours going in circles i feel. No matter what I try
the result is the same.

Basically, a black-white pixelated screen with a X curser (that I can
move), and that is about it.

I won't hypothesis with what I have been able to discern - as obviously,
it has not worked.

i have two different Debian 10 boxes, what I would like to access via
VNC so i don't need to attach KVM.

They have absolutely WORKED in the past, and I haven't meddled with them
in a way that would cause them

to break. I don't recall doing any updates (which normally I am slow to
do). So that adds to my perplexity.

They both have TightVNC installed, and the identical xstartup vnc file:

#!/bin/bash

xrdb $HOME/.Xresources

startxfce4 &

They both have rw+x access to them. I can start the vncserver from the
command prompt just fine (normal users, without sudo), and even connect,
tried with sudo and with the actual root!

to both machines, but then just the aforementioned screens. I have tried
tunneling in via SSH, same result.

I have tried connecting from two different clients (running vnc
connect), one Mac OS and one Windows 10. All same result.


I have tried various xstartup files I have searched around online that
seemed like they might help, but nothing.

I have read through the log file

xrdb: No such file or directory

xrdb: can't open file '/home/username/.Xresources'

/usr/bin/startxfce4: X server already running on display :1


I am running Gnome on both desktops. Ah! That's why the other one worked
in the past -- I was not running Gnome on it. But, that doesn't bring me
closer to a solution other than not running Gnome on the two machines,
which I would rather not do, they are robust enough to run Gnome.


Any advice help or encouragement would be appreciated.

VLC has a remote control feature -- several, actually. Control
can be handled by a command line, Lua, telnet, or http, among others.

Normalize the volume of the mp3 files beforehand rather than adjusting
the volume of the player in real time for each individual file (e.g.
with an app like python-rgain)? 

Or does this not speak to the reason for the volume changes?

OK, now I get your objection: the colours "outside the loop" are
many and different. Perhaps the loop's colour is "different enough"
from every other, as determined by the fuzz metrics, then you are
lucky. Perhaps not. Then a more elaborate pipeline is necessary.

Yep. That's one dificculty. Got it now. OTOH, if your loop isn't
"different enough" in colour from the rest of the image, how do
you differentiate it?

ImageMagick has many other more "intelligent" operations, but to
be able to pick one, the original problem has to be more specified,
I think.

I must have missed the cropping part in the OP's request. But then,
once the main problem is solved, ImageMagick has tools for that.

Another, more precise possibility is to use the "connected component
labeling" [1]: you have to then "know", by image coordinates, for
example, which is the one you want to keep. Basically, a multi-level
flood fill :-)

Ah, right, I'd missed the "color that matches" part of the phrase. That
does significantly change the meaning of the definition at that given
link, to something which matches much better with what I'd have expected
the term to mean in the first place.

In that case this seems like an even less suitable match for the request
as I parse it.

I either am badly confused, or don't understand how this relates to the
request at all.

If I'm reading the original request correctly (which I'll admit is by no
means guaranteed), the "single color" used to draw the "loop" - i.e.,
in the example, black - is incidental to the goal; it just defines the
boundary of the region which is to be left unchanged. It may or not even
be important to retain the colored perimeter line in the result; I'd
intuitively expect not, but there could be reasons to do so.

What's outside (or, if you prefer, "on the other side of") the boundary
may well be thousands of different colors, not necessarily in any
pattern which the program can be expected to recognize with relation to
another. The important part of the request is wanting to overwrite all
of that region outside the boundary - regardless of its initial color -
with a single, specified color (for values of "color" that include full
transparency).

I don't see how "flood fill" can fulfill that at all. My best guess
would involve the mention at your given reference link of a "-fuzz"
option which lets the color matching be inexact; that could potentially
make it possible to have a "define the boundary" color which is
sufficiently distinct from every color in the external region that the
fill will be able to match and replace all of the latter but will reject
and neither replace nor propagate past the former, but it seems
improbable that it would be practical to have this distinctness hold
true for every image you might want to process this way.

(Then again it'd also seem impractical to guarantee that whatever color
is chosen for defining the boundary will not occur outside of the
boundary; I think that's why I've been mostly assuming that the literal
drawing of the boundary with a color is just part of an attempt at a
solution to the problem, not an essential part of the problem definition
itself.)

It comes in if the relative location of the specified region compared
against the edges of the canvas is important.

If you stay with just one image (canvas), and replace everything outside
the specified region with a specified color, then the relative position
of the region remains unchanged.

If you copy the region into a new image (canvas), it will be placed
wherever the program decides to put it relative to the edges of that new
canvas, which may or may not wind up having any similarity to its
location on the original

No, no. Unless you mean "distance in colour space". Look again at
the given ref, [0].

Flood starts at a pixel, considers every neighbour [1] having the
same colour [2] and repeats that process for those selected neighbours,
until all possibilities are exhausted. Optimising that is left as
an exercise to the reader, as they say :-)

It's a "classic" in bitmap and pixmap graphics.

Yes, but then, one person's "inside" is the other person's "outside".
You just have to choose judiciously your start point (aka "seed").
And, of course, make sure the region thusly defined is connected.

If you think your "border" (Emanuel's "black loop") extends so far as
to multiply touch your image frame (so as to yield several disconnected
regions), you better extend the image a bit in every direction somehow.

But wait! that's what ImageMagick already does... magically, with its
VirtualPixels [3], the default being 'edge', so just what we need.

The (flat) world is a sphere, after all (at least in the context of
flood fill, that is).

Gimp does a great job offering a tool to select the region which must be
retained. A simple click later, you are done.

Convert is great for automating the procedure, but I venture that the
constraints are too difficult to meet to make it work on a big number of
pictures.

At least I would be interested to be proven wrong.

Your request is a bit... unspecific.

actually see the image you described above, and where you can click

Or is it (b) rather some kind or "batch mode", where you give the

For ease of search, the operation you're describing is usually called
"flood fill". If you are after (a), your friend is The Gimp; I guess
Krita will fill that bill as well. If it's (b), the usual standard is

flood fill.

I think you may have misunderstood the request - either that, or I did.

 From the description of "flood fill", what it does is replace everything
within a certain distance of a specified point with a specified color.
That maps to "fill a specified region with a specified color", if the
region is radius-based.

What I understand the request to be is for a way to replace everything
*outside of* a specified region with a specified color, where the region
is *not* necessarily radius-based but may potentially be freeform.

If I needed to do that, what I'd probably wind up doing is to select the
desired region, copy it, paste it into an empty image, and adjust its
position and the size of the image to suit. I don't know of any tool to
automate the process to any meaningful degree.



The requirement seems to be to infill an image inside a bounding line.

This is what happens in postscript rendering when a raster algorithm 
scans a page containing a path defined by some geometry e.g. Bezler 
curve, and every time it crosses the curve on a scan line it changes 
from writing nothing to writing the infill color and back again at the 
next curve intersection


This happens on every character on every page you print on a postscript 
printer. It's a really basic image algorithm.


If it's possible from a script I'm not sure? but it's so simple it's 
very likely

I think you may have misunderstood the request - either that, or I did.

From the description of "flood fill", what it does is replace everything
within a certain distance of a specified point with a specified color.
That maps to "fill a specified region with a specified color", if the
region is radius-based.

What I understand the request to be is for a way to replace everything
*outside of* a specified region with a specified color, where the region
is *not* necessarily radius-based but may potentially be freeform.

If I needed to do that, what I'd probably wind up doing is to select the
desired region, copy it, paste it into an empty image, and adjust its
position and the size of the image to suit. I don't know of any tool to
automate the process to any meaningful degree.

That is a mystery which noone ever could resolve. There is pratically no
experience with this tool and no hints have ever been published. I think
the whole thing is utterly useless and that it has never made any sense
to publish this stuff anyway.

Let us just give up and go home, now.

Re: Linux i disc NAS

[Jordi]

Ja solucionat el problema, crec que en el meu cas no m'he de complicar
més i continuar utilitzant rsync i minidlna. El problema va ser no
netejar el disc nou i vaig arribar a pensar que un disc de NAS no es
podia ficar al PC. Finalment, i amb ajuda, el Linux ho pot tot.
Gracies

Your request is a bit... unspecific.

Are you (a) after a tool which you use interactively, where you
actually see the image you described above, and where you can
click into that loop to start the operation?

Or is it (b) rather some kind or "batch mode", where you give the
program the image file *plus* the coordinates of that point inside
the loop where to start?

For ease of search, the operation you're describing is usually
called "flood fill". If you are after (a), your friend is The Gimp;
I guess Krita will fill that bill as well. If it's (b), the usual
standard is "mogrify", from the ImageMagick suite. Look at [1] for
the details on flood fill.

Getting warm with the ImageMagick programs takes a bit of practice,
but it's worth it. Come back if you get stuck.

Okay pour une fusion de #973515 et #973919 ?  Apparemment, les
deux rapports traitent du même problème, en première lecture.

Ah, oui, la locale est un peu cachée.  Chez moi, en lançant
`dpkg-reconfigure locales`, j'active C, en_US.UTF-8, et
fr_FR.UTF-8 occasionnellement ; il me semble qu'il faut au moins
une locale UTF-8 pour activer le C.UTF-8.  Ensuite le panneau
suivant me permet de choisir la locale par défaut entre C,
C.UTF-8, en_US.UTF-8 et fr_FR.UTF-8, et c'est là que je peux
sélectionner C.UTF-8.

Je ne connaissais pas localepurge.  Au vu de la description, je
pense que ça vaudrait le coup de le sortir de l'équation, pour
s'assurer que ce n'est pas un bug dans ce paquet qui provoque
les problèmes que vous rencontrez.

Apparently mpv supports setting the volume from command line, as does 
(of course) mpd via mpc.

It depends on whether you have the corresponding linux-image-

Le fichier existe sur mon système (Buster assez fraîchement installé).
Il appartient au paquet "login".

Ok, je parie que tu ne fais pas tourner Buster mais plutôt Testing ou
Unstable. Vrai ?


En plein dans le mille ! Je suis sous Testing


En effet login ne fournit plus /etc/securetty après Buster [1][2] d'où
ta sortie de commande différente de la mienne+Sébastien.


Ok, je ne savais pas.


J'ai l'impression que ta remontée est du même acabit que le bug #931899 [3].


En effet, c'est très probablement la même chose chez moi,


Auquel cas, vu que le fichier n'est plus fourni, pam devrait arrêter de
proposer des options qui y font appel au-delà de Buster.


Ce qui semble logique en effet.


Il semble que la ligne fautive soit dans /etc/pam.d/common-auth, plus
précisément l'argument "nullok_secure" envoyé au module pam_unix.so.



Je te laisse regarder si t'as bien cette ligne. Sous Buster chez moi
c'est la suivante : auth    [success=1 default=ignore]  pam_unix.so
nullok_secure


Oui j'ai bien ça.


Visiblement, supprimer "nullok_secure" résout le pb d'accès.  Pas
certain que ce soit une perte de sécurité dans la mesure où cet
argument autorise lui-même une certaine largesse...


Bon, je me lance, on verra bien si le monde arrête de tourner après ça.


nullok_secure: The default action of this module is to not permit the
user access to a service if their official password is blank. The
nullok_secure argument overrides this default and allows any user with
a blank password to access the service as long as the value of PAM_TTY
is set to one of the values found in /etc/securetty.


Tous mes utilisateurs ont un mot de passe.

Merci à toi et très bon dimanche !

Això passa perquè mdadm analitza els discs per trobar si hi ha
cap RAID definit i tornar-lo a muntar. És una característica molt
útil si vols moure els discs d'un RAID a un nou servidor físic,
però si vols reutilitzar el disc pot donar problemes tret que el
netegis primer (n'hi ha prou netejant el principi, tal com s'ha
explicat en un altre fil).
