Your comment bolsters my suspicion that Linux kernel support may have regressed 
lately for Radeon "AGP" gfxchips marketed in parallel to PCIe versions:


https://lists.opensuse.org/opensuse/2017-03/msg00163.html

Similar wasted a bunch of my time very recently:
https://bugzilla.opensuse.org/show_bug.cgi?id=1004453#c30

One must wonder how much time and effort kernel devs devote to testing on 
ancient, mostly 32-bit, hardware.

When you say get rid of drivers, is that just things like
xserver-xorg-video-foo, or do you also mean things like
kernel modules?

This laptop uses AFAICT the xserver-xorg-video-radeon
package (xserver-xorg-video-all is installed) with lines like:
(II) LoadModule: "radeon"

But long before this, the kernel loads a module called radeon.
I think the latter sometimes gives me problems. For example,
during the previous kernel, exiting X would often lead to the
machine apparently sleeping. The only way of awakening it was
pressing the power button momentarily, whereupon it would wake
up only to shutdown. Well, at least that avoided fscking.

Another oddity is that dmesg always says (both then and now):

As I mentioned in my first post, it is a display issue. The BIOS boot screen
never displays, nor does any of the boot sequence, when using the Radeon R9
270X card. Forcing it into the BIOS setup won't make it display the screen
it can't display without forcing it into BIOS. Hence, all setup has to be
done using the integrated Intel graphics, with the switch to the PCI graphics
card the final step

Something is defective, MSI's motherboard BIOS/firmware, Radeon's VBIOS,
hardware, display or some combination. If all acquired together, it ought to 
have been taken up with the vendors when new so that you would have had

some recourse. Maybe you still can. Do you have the latest motherboard
BIOS/firmware?
From https://www.msi.com/Motherboard/support/Z87-G43.html#down-bios :

"2015-05-12 1.B
- Improved AMD Graphic card compatibility.
...
- Updated VBIOS and GOP Driver.
- Hide item "IGD Multi-Monitor" when "Initiate Graphic Adapter" set to IGD."

Run dmidecode to see if yours is older. 1.A is 2014-07-29. 1.9 is 2014-07-07. 
... 1.0 2013-04-02.



In Wheezy I had 4K using either the Radeon or the integrated graphics. In
Jessie I can only use the integrated graphics.

Now that you have shared this tidbit we know that either your hardware has gone
bad between Wheezy and Jessie, or a software regression has occurred. If the
latter, it should have been reported as a bug so that it could be fixed. The
devs don't spend much time fixing what they don't know is broken. Stretch is
just about ready to go out the door, so it's probably already too late to expect
a report to result in a fix in Debian's "next" release.

The OP is the guy still trying to get a fingerprint reader

Perhaps, like me, they were perfectly happy with running wheezy
but, unlike me, they have a piece of new hardware that requires
a more modern kernel or whatever.

What was the previous server and port number that you used
previously for sending?

I can connect to smtp.illinois.edu on port 587 just fine, though
I obviously have no login credentials (and don't want any).

It looks to me as if you may be connecting unencrypted, and then
trying to start TLS. I connected encrypted, received a certificate,
and then I said "ehlo junk". I received:

250-smtp.illinois.edu Hello [192.17.23.217]
250-SIZE 104857600

250-ENHANCEDSTATUSCODES
250-AUTH GSSAPI NTLM LOGIN
250-8BITMIME
250-BINARYMIME
250 CHUNKING

It seems a bit dated, having AUTH LOGIN but no PLAIN.
I think that just means you send the username and password separately,
rather than together in one line.

I do imaging for system disks.  I do backups and archives for data.


So having evangelised file-level copies a few times in this thread, I found
myself wondering if I would have been better off with imaging this very
weekend. Copying a 2.1T filesystem from an internal SATA2 disk to an external
one (my regular backup drive to my once-a-month, lives off-site one) via USB3
took nearly 48 hours via "rsync -a",


2.1 TB / 48 hr / 3600 s/hr = 12.2 MB/s

I was also disappointed by the transfer rate of external USB drives on 
Debian.  Firewire is better.  eSATA is best.



I now use 3 TB Seagate ST3000DM001 desktop drives in StarTech 
DRW115SATBK mobile docks connected to motherboard and/or HBA SATA ports. 
 With LUKS and a Pentium D 945 (no AES-NI), I see 40 MB/s.  With LUKS 
and a Core i7-2600S (AES-NI), I see 220 MB/s.




and the destination ended up bigger,
possibly because one or more of the backups on the source had been using some
kind of hardlink de-dupe (I've ranted about hardlink trees being a problem in
various backup topics on -user, too...) and I didn't think to supply -S to
rsync.


-S is for sparse files.


Doing a quick test, it appears that rsync copies hard linked files as if 
each were a different file:

Is anyone aware of a utility that can walk a file system and replace 
identical files with hard links?




The real test will be how long an incremental catch-up will take in the future.


For new large files, the size of the files divided by 12.2 MB/s.  For 
everything else, longer.

Thank you. While I would prefer to use the Radeon card, the Intel graphics are
quite sufficient, and do indeed provide me with 4K resolution. Why mess with
success, e.g 4K graphics and access to the BIOS?

Will it provide me with a 4K display?
I have no idea whether your 4K display is compatible with anything in Jessie.
Pure Jessie might be too old.

Since my Intel graphics work perfectly in Jessie, at 4K, I see no reason why
the more powerful Radeon card would not.

You haven't provided model or known modes supported of either your display or
your CPU, or your cable connection type you're using or have tried to use, or
what mode you actually want to use. These limit what help you might be able to
get from any mailing list.

Please provide a reference that states my card is supported by it, as well.
Full specifications for the R9 270X seem to be a secret. I searched the web
without finding out what specific modes it is supposed to support.

e.g. https://us.msi.com/Graphics-card/R9-270X-GAMING-2G.html#hero-specification
suggests it ought not be the limitation, but lists no modes at all.

http://xfxforce.com/en-us/products/amd-radeon-r9-200-series/amd-radeon-r9-270x-double-dissipation-edition-r9-270x-cdfc
says maximum resolution via Dual-link DVI is 2560x1600. That's less than 4K, so
you can't use that cable type to get 4K. With the right DisplayPort or HDMI
cable, you should be able to get 4K, but cables don't always live up to claimed
specifications.

I don't have your hardware, so can't guarantee anything.

I am indeed using a Displayport cable; my HDMI cables don't work at 4K. In
Wheezy I had 4K using either the Radeon or the integrated graphics. In Jessie I
can only use the integrated graphics. The fglrx driver is incompatible (with
Gnome3 apparently, but it must be all aspects of Gnome3 as I use xfce with the
gdm). As I mentioned before, blank screen. It apparently boots, but nothing
ever displays, using the radeon driver. I am waiting patiently to see what
Stretch brings in this area.

You did not mention whether the driver you recommend provides 4K support, or a
reference confirming it supports my card.

have filed a wishlist bug requesting this feature.


This seems like at least a contributory reason.

In Jessie the modesetting driver is still a separate package, but

I've not tried to find and read the manual for your motherboard, but it's

Speaking as someone who has preferred Debian on servers since woody,
I remain happy to run Debian on all my servers and am reasonably
happy with systemd. Any other Linux I could imagine ever switching
to also now runs systemd by default and I would be unlikely to seek
to change that.

I suspect that if you counted every instance of an init system
running "in the cloud", most of them would be systemd. The most
popular OS in the cloud is Ubuntu¹ - with systemd. CoreOS², which
was designed from scratch to be run in the cloud, includes systemd
as a non-optional component.

I am not aware of any mass exodus of server administrators away from
systemd. Quite the opposite in fact, simply because most
distributions switched to it.

It is perfectly okay for someone to dislike systemd, or any other
piece of software, but if you are going to make statements that
appear to be on behalf of all server administrators then I think you
need to show your working.

Cheers,
Andy

That might be because all of those who run servers - the traditional

Meanwhile, my MSI Z87-43G motherboard boot screen doesn't display unless I use 
the built-in graphics card. When I use my Radeon R9 270X it just goes blank, 
but still boots through to the default first grub menu item. 4K monitor. Of 
course, the obvious issues with my graphics card means I don't use it. The 
newer driver for Radeon cards does not support my card, and the old Catalyst 
driver is incompatible with Jessie.

Weet ik niet. Wellicht gaat het om een cronjob die bij een Debian
package hoort. Ik zie er verschillende, "locate" en "apt" bijvoorbeeld.
Ik draai geen eigen script met daarin het commando "find".

Er zijn veel meer processen zijn die oom-killer "invoken". Find was wel

If you can read directories and files, then you can backup them.
If you can create new directories and write new files, then you can
restore the backup.
If you cannot, then it's hopeless.

You have a Samsung ML-191x series B printer. It is not supported in
Debian. From where did you get the necessary drivers?

Encouraging. CUPS has detected the printer is on a USB connection. There
should be no problem printing after your basic problem is sorted out.

This is the first thing that happens to any submitted file. You sent a
PDF file to the printer. No problem here.

Eh? The printer does not recognise PostScript. It would print garbage if
it got it. I wonder why the filtering system thinks converting a PDF to
a PS file is needed. Is there any sign of "gstoraster" in your error_log?

IPv6 et "Stable Privacy" (RFC 7217) sous GNU/Linux ?

2017-03-13 Thread Christophe


Bonjour à tous,

Ce post n'est pas forcément spécifique Debian mais si ça peut aider les 
utilisateurs de la liste ... ;) .


Je cherche à savoir s'il y a une configuration noyau ou tout du moins 
système qui permet de faire fonctionner l'option "Stable Privacy" (RFC 
7217) sous Debian , et sous Linux en général.


L'avantage est d'utiliser l'adressage automatique sans état, sans 
utiliser l'adresse mac pour se faire, et conserver quand même une 
adresse fixe dans le temps à la différence des "Privacy Extensions" (RFC 
4941), et des adresses temporaires.


(entre autres , c'est ce qui m'a fait passer de 18 à 20/20 sur 
http://ipv6-test.com/ :) )


La seule référence que j'ai trouvé de manière sure (et c'est moche d'en 
arriver la) , c'est NetworkManager et l'option configurée dans le 
fichier de connexion (ou en global si on veut que cela s'applique sur 
toute nouvelle connexion).


[ipv6]
addr-gen-mode=stable-privacy


En revanche la doc semble se faire maigre quant à l'utilisation de 
sysctl (par exemple) pour l'utilisation de la dite RFC sur des machines 
sans gestionnaire graphique. Apparemment ça se situe quelque aux 
alentours de :


net.ipv6.conf.X.stable_secret

Mais aucune idée du format de ce champ, ni même si c'est la seule option 
nécessaire, et encore moins de ce que NetworkManager manipule/bidouille 
pour y arriver ...


Plus encore, existe t'il un paramétrage "Debian Like" de 
/etc/network/interfaces qui permettre de le faire ?


Auriez vous des informations à ce sujet ?

Re: If Linux Is About Choice, Why Then ...

2017-03-13 Thread John L. Ries

You do have your choice of distros and most distros provide wide
lattitude as to what software to install, what GUI (if any) to run, what
shell to use (my preferred poison is ksh, not bash), etc.  I'm not all
that fond of systemd myself (though my relationship with it is
improving), but there are still distros that use old fashioned init
(Slackware comes to mind).

And all of the above constitutes a lot more choice than you get from
either Apple or Microsoft.

Ooohhh, NICE find! I never would have thought about it because I've
never seen apt-show-versions produce that output.

I started to write: Is there a way to perform maybe a "reverse" grep
sent to a file that was an "apt-show-versions -u" (or any other) query
with everything EXCEPT those packages that return "No available
version in archive"?

And then I went to "man grep" = THERE IS A WAY

At least it worked on my end.

I don't have anything that's not from that one-liner repository I use
(in /etc/apt/sources.list) so I tried:

apt-show-versions | grep -v "uptodate" -i

That "-v" is interchangeable with "--invert-match". Both allow you to:
"Invert the sense of matching, to select non-matching lines"

Better yet, I just did:

apt-show-versions | grep -v "uptodate" -i > notUpToDate20170313

THAT... returned ONLY the lines that did NOT contain "uptodate" out of
the tons of packages I have installed AND then sent that query to a
file that is easier FOR ME to read and manipulate (versus seeing it on
the terminal display).

I A-SUME but cannot test drive that the following MIGHT be usable for
someone somewhere... some day:

apt-show-versions | grep -v "No available version in archive" -i >
thePackagesIwanted

OR, depending on your need, maybe something like:

apt-show-versions -u | grep -v "No available version in archive" -i >
thePackagesIwanted

Yes, no, maybe so?

For those who have not seen the ">" yet, that was a tremendous tip I
learned on the fly years ago. It outputs what you're doing to a file.

There's a no-brainer "caveat" to using that. You must have rights to
access the directory that you're issuing that command from, else it
WILL fail. E.g. I can't issue that command while my terminal is
showing that I'm sitting in the /etc directory. It DOES work if I
change the file path to "~/notUpToDate20170313", e.g.:

elf@northpole:/etc$ apt-show-versions | grep -v "uptodate" -i >
~/notUpToDate20170313

I say again... Oooo :)

Because the number of people who want to run a new version of Debian with
an ancient and deprecated init system is probably in the triple digits,
worldwide.

You are a member of a small minority.  It's not reasonable to expect
that a whole bunch of time will be spent making install images with
alternative init systems for such a small demand.  You have a solution
which works just fine.

Oom-killer zonder geheugengebrek

2017-03-13 Thread Paul van der Vlis

Hallo,

Ik heb een raar probleem: oom-killer wordt aangeroepen terwijl er geen
tekort is aan geheugen. Swap wordt niet aangesproken.

Heeft iemand een idee wat dit zou kunnen zijn?

Het zou een probleem met het swap-geheugen kunnen zijn, daarom heb ik
dat net opnieuw aangemaakt met "mkswap -c", van "check".

Ik zie ook verschillende keren de term "tainted" voorbij komen, terwijl
ik geen closed-source drivers gebruik op deze machine. Zoiets:

Er wordt ECC geheugen gebruikt.

If Linux Is About Choice, Why Then ...

2017-03-13 Thread Patrick Bartek

The Linux mantra has always been "choice," plethoras of choices. So why
at install time, is there no choice for the init system?  You get what
the developers decide. Yes, you can install a new one -- I've done it
and it works -- but only after the install.  It'd be a lot easier, if
there were a choice to begin with just like whether you want a GUI and
which one.

Now, I know with LFS, you get to choose everything, etc.  But is a
choice of init at install time so outrageous that no one ever
considered it or is it technically unfeasible or something else.

Just curious.

The file in question was actually /var/mail/mail and if it exists it
will be owned by mail:mail on Debian, though.

It's where mail for root goes to if delivered locally to an mbox
format spool file. At no point does a /var/mail/root get created as
the system won't want to run an MDA as root and this also avoids
having to run an MUA as root to read it.

But best practice is to send root's email to a regular user or list
of users.

Cheers,
Andy

Re: Apology to siduction 17.01 (was Re: why??why?why??)

Hi there


On 13/03/17 15:54, GiaThnYgeia wrote:


Out of my frustration and lack of understanding, or the belief that all
systems should run as trouble-free as clean-debian, and possibly due to
just getting tired of fighting something too long, I bad-mouthed
siduction in public.

My source of frustration came from fighting an installation in a tired
old system (64bit) and a mediocre not so smart monitor.  Most installers
and systems I've seen use 800x600 as their boot/grub screen.
Siduction probably doesn't have access to an old monitor.  What this
meant was the screen would blank out and have an internal error showing
not-compatible meanwhile the grub time would expire and boot up
eventually to a graphical login screen.  So I thought some weird boot
system prevents me from seeing what's going on or giving me options, so
in effect I lost access to all other installed systems.

With a clean head and a different pc I went in as root and looked on the
usb what the grub config looked like and simply replaced the high
resolution to an 800x600 and delayed the default boot sequence just in case.

Siduction ... the best grub-configuration I have seen yet, once you can
get to it and edit it :)

Sorry Siduction!
kAt

PS  But you (siduction) should lower your graphics expectations down a
notch or two.  There are some 1024 monitors still around.


My server has a 12 Inch 640x480 monitor (IBM 8513).
Installers shouldn't make assumptions about resolutions.


PS2  Maybe a way to scale back and confirm visibility of the grub menu
before it boots the default may help, if you MUST high a high definition
grub screen.

PS3  Being more confident I can back up and restore my experimentation
with siduction really did help as well ;)  dd/xorriso and all!

PS4  More than a week ago when I subscribed to their forum "I asked" on
why would their installer not run on very similar systems.  Never
thought the monitor was IT.  I got no response from them ... but I
assume small teams of developers can't address everyone's complaints.

Read the wiki and find out how to activate debug logging. Produce an
error_log and examine it for the filters which are run and which one
failed. Tell us about all the filters.

Also, post your printer make and model and the output of 'lpstat -t'.



I noticed that CUPS does not really provide the PPD file I'm adding.  In
fact, there in the managing section, `Modify Printer', where it says `Or
Provide a PPD File', I select the file: ML-191xspl2.ppd, which is in my home
directory, then click on `Modify Printer' and it seems all right; but then,
when I get into it again, the file is no more there, and there is `No file
selected' instead.  Maybe this is related to my `Filter failed' problem...?


There are seven instructions in the advice given. You haven't provided a
response to any of them. If there is a problem with following what is
required, please ask.


As the wiki suggests, I did:

 # cupsctl --debug-logging

.  Then I did:

Re: Some help with dd backing up into an iso

Very good information but the word sudo comes up everywhere.
If a user does not have sudo rights she/he can back-up files and restore
them as long as s/he has rights to what their backing-up/restoring.  So
if you are in a network public environment you may not even have rights
to even your own disk if some of it is somehow protected.  And in some
places to protect the system and network mounting media is not allowed,
bios may be locked and prevent the machine from booting anything other
than its networked drive.

Just for the sake of something (maybe collecting nits?), I believe this (that 
is, sending to  boudic...@skimble.plus.com) will work only if (1) you have an 
email server installed (I'm pretty sure Debian does that by default, and (2) 
that email server is configured to send / relay mail via your ISP, which, ime, 
is not done by default on a Debian install.

Instead many (or at least some) of us have what I call a Windows style e-mail 
client, that is, one that sends emails to others on the Internet directly from 
that email client using, for example, SMTP.  I use kmail, getting my mail via 
pop3, and sending via SMTP.

Yes, tinkering with the UEFI of the machine is a good idea, particularly
switch off secure boot, tpm and the like. Also HP is known for its
non-standard implementations of UEFI. And in this case, for the z240
series, Ubuntu seems to be a commercially supported OS by HP, unlike
Debian, that could be a hint...

I tried to boot with variations of these options
"DEBIAN_FRONTEND=text|newt|gtk and vga=normal fb=false", but no luck.
I was also comparing "boot/grub/grub.cfg" from Debian and Ubuntu. I
found that Debian has there all that Ubuntu has and even more

Don't know what to do.

Re: Some help with dd backing up into an iso

Hi,

the restore scenario for the xorriso backup would be like this:


- Prepare the storage device to which you want to restore.
  This may be as simple as choosing some directory in a filesystem with
  enough free space, or as complicated as setting up a new operating
  system on a freshly purchased hard disk.


- If the backup has some history of copying or transmission (e.g. by
  being burned to a DVD), then first let xorriso check whether it is
  still undamaged:

iso=/dev/sr0

xorriso -for_backup -indev "$iso" -check_media --

  will check the MD5 of superblock and directory tree and then read the
  whole ISO sequentially to look for the MD5 checksum tags. Those MD5s
  were stored by xorriso during the write run with setting -for_backup.

  Example of how a goot verification should look like (with lower speed
  if read from a real DVD):

xorriso : UPDATE : Found matching MD5 superblock tag: start=32 size=18
xorriso : UPDATE : Found matching MD5 tree tag: start=32 size=302
xorriso : UPDATE : Found matching MD5 session tag: start=32 size=81217
xorriso : UPDATE : 81250 blocks read in 1 seconds = 120.1xD
Media checks :lba ,   size , quality
Media region :  0 ,  81250 , + good
Media region :  81250 ,158 , 0 untested
MD5 checks   :lba ,   size , result
MD5 tag range: 32 ,  81217 , + md5_match

  "Media region" with quality "+ good" means that there were no i/o errors.
  "0 untested" means that these blocks are not claimed by the ISO filesystem.

  "MD5 tag range" with result "+ md5_match" means that the MD5 checksum
  of the inspected region matches the recorded MD5.


- If you just want to pick some files by help of your favorite file
  copier tool, then mount the medium

iso=/dev/sr0
sudo mount "$iso" /media/user/iso

  or if the ISO is in a data file rather than on a DVD

iso=usb_part1.iso
sudo mount -o loop "$iso" /media/user/iso

  Now you may copy files from /media/user/iso to the place where you want
  them to be. My favorite would be cp with option -a, possibly under sudo
  control for the power to assign file ownerships.
  (Caution: This can of course shoot your foot if you do not take care
when composing the cp command.)


- If you want to copy the whole ISO content from DVD to a directory tree
  on hard disk or if ACLs and Extended Attributes matter, it is advisable
  to let xorriso copy the files out of the ISO:

target=/my/prepared/restore/directory

sudo xorriso \
 -osirrox on:sort_lba_on:auto_chmod_on \
 -for_backup \
 -indev "$iso" \
 -extract / "$target"

  Only the superuser or sudo are permitted to assign file ownership to
  other users. Omit "sudo" if all restored files shall belong the user
  who operates xorriso.

  The -osirrox setting "on" enables command -extract. Setting "sort_lba"
  lets xorriso read the files from DVD in the order of their content
  block addresses. This avoids slow and loud laser head movements.
  Because this reading order may cause revisiting of directories which
  were already restored without wx-permission, the setting "auto_chmod_on"
  permits xorriso to temprorarily grant its user those permissions.


Have a nice day :)

[debian/stretch] problems playing zipped midi file on console

2017-03-13 Thread Ennio-Sr

[Duplicates a post to _debian/italian@..._]

Hi all!

I hope somebody can help me solve this dilemma:

I have two PCs with the same debian version and (to the best of my
knowledge) the same configuration, at least AFA _/etc/mime.types_ and
_/home/user/.mailcap_ is concerned.

However, when I try to play a  zipped midi file (from within _lynx_) the
two PCs behave differently: one plays it using timidity, whereas the
other asks to Download or Cancel the file.

BTW, _/etc/lynx/lynx.cfg_ and _/home/user/.lynxrc_ are also the same.
Can you suggest what else should I check?

Thanks for your attention, regards Ennio

Perhaps apt-show-versions, which can check whether a package
is in a repository. You will need options and/or grep.

For instance, on one of my machines, I get in the output:

unison2.40.102:amd64 2.40.102-3 installed: No available version in archive

i.e. apt-show-versions detects that this package is installed,
but no longer in any declared repository.

AFAIK, aptitude can do similar things.

"rc" means that the package has been removed but its conffiles are
still there (i.e. the package has not been "purged").

You can get the list of remaining files with:

  dpkg -L 

You can purge the package (i.e. remove all the conffiles) with:

  dpkg -P

Note: There is a package that downloads the non-free Flash plugin.
These files are not from the package, thus will not be detected
by dpkg. If you have used it and purged the package, you should
manually check that everything has been cleaned up (perhaps this
package ensures that, though).

Apology to siduction 17.01 (was Re: why??why?why??)

Out of my frustration and lack of understanding, or the belief that all
systems should run as trouble-free as clean-debian, and possibly due to
just getting tired of fighting something too long, I bad-mouthed
siduction in public.

My source of frustration came from fighting an installation in a tired
old system (64bit) and a mediocre not so smart monitor.  Most installers
and systems I've seen use 800x600 as their boot/grub screen.
Siduction probably doesn't have access to an old monitor.  What this
meant was the screen would blank out and have an internal error showing
not-compatible meanwhile the grub time would expire and boot up
eventually to a graphical login screen.  So I thought some weird boot
system prevents me from seeing what's going on or giving me options, so
in effect I lost access to all other installed systems.

With a clean head and a different pc I went in as root and looked on the
usb what the grub config looked like and simply replaced the high
resolution to an 800x600 and delayed the default boot sequence just in case.

Siduction ... the best grub-configuration I have seen yet, once you can
get to it and edit it :)

Sorry Siduction!
kAt

PS  But you (siduction) should lower your graphics expectations down a
notch or two.  There are some 1024 monitors still around.

PS2  Maybe a way to scale back and confirm visibility of the grub menu
before it boots the default may help, if you MUST high a high definition
grub screen.

PS3  Being more confident I can back up and restore my experimentation
with siduction really did help as well ;)  dd/xorriso and all!

PS4  More than a week ago when I subscribed to their forum "I asked" on
why would their installer not run on very similar systems.  Never
thought the monitor was IT.  I got no response from them ... but I
assume small teams of developers can't address everyone's complaints.

A quick overview:

Nobody wants backups. Everybody wants restores.

The questions are: 

- what sort of disaster are you trying to recover from

- how often do you expect each to happen

- how much time are you willing to take recovering

- how much are you willing to spend

Let's take a few common scenarios.

First: a house full of personal use machines, plus a server. We
expect files to go missing or be accidentally deleted fairly
often, and we want it to be easy and cheap to recover from that.

The general answer for that is to store files on a networked
filesystem of some sort - NFS, SMB, sshfs, whatever - which
resides on the server and is snapshotted every so often. Tools
for snapshotting include LVM (not recommended), rsnapshot, and
btrfs and zfs. Anything with a user-accessible snapshot method
is good here - sysadmins don't need to be involved in every
oops.

Second: we have the same setup, but we would also like to make
it reasonably easy to restore a whole machine when we have an
accident with the hard disk.

For that, we need image backups over the network to the server.
We won't want to snapshot these, just keep the most recent good
image. Testing these every so often is necessary.

Third scenario: running a service that makes you money. For
this, we want to be up all the time. We can spend a lot more
money on this, because we expect to make money from it.

The solutions here involve high availability: multiple machines,
possibly in multiple locations, handling the same service in a
coordinated fashion. Users need to be automatically directed to
a working instance, and we need a monitoring system to tell us
when a machine is down, because if the HA system is working we
will not get user complaints.

Re: Some help with dd backing up into an iso

Hi,

fresh mail from GiaThnYgeia:
> So I decided to run the whole script as sudo or sudo xorriso and it
> seems the problem is solved.

Good to know. You are now supposed to have a copy of the files and
directories of the USB stick.


> Should I attempt to rebuild it to a test disk to see if it reliable?

The disk still needs partitioning and possibly boot equipment.
In case of real backup restoration you will need to rebuild these data
by tools like parted and grub.

That's why a (compressed) dd copy of the not mounted USB stick is the
quickest way to get back the whole disk layout.

The ISO provides easy access to the single files. A test for reliablility
would rather be in comparing both file trees:

  sudo mkdir /media/user/iso
  sudo mount -o loop usb_part1.iso /media/user/iso
  sudo diff -q -r /media/user/sid /media/user/iso | less

Program "diff" will list files with differing content.
So no output is a good sign then.

When done, unmount the ISO:

  sudo umount /media/user/iso


You may of course restore the ISO content to some directory in some
filesystem. I will discuss your options in respect to this in another
mail. I have some things to do right now.


Have a nice day :)

If you were not superuser or ran xorriso under sudo, then the ownership
and permissions are a valid reason for being unable to read its content.

I do not generally advise to make backups as superuser. But since the
mounted USB stick probably contains files of many users with various
permission sets i now propose to become superuser or run xorriso under
control of program sudo:

   sudo xorriso \
   -for_backup \
   -outdev usb_part1.iso \
   -map /media/user/sid /

Well, it's the boss directory which we do not want to backup.
Nevertheless, Debian's build of xorriso run with settimg -for_backup
will record ACLs and Extended Attributes. Linux mount will not show them,
but xorriso will be able to restore them.

It indicates the presence of an ACL (file access control list), as
documented in "info coreutils ls":

 Following the file mode bits is a single character that specifies
 whether an alternate access method such as an access control list
 applies to the file.  When the character following the file mode
 bits is a space, there is no alternate access method.  When it is a
 printing character, then there is such a method.

 GNU `ls' uses a `.' character to indicate a file with a security
 context, but no other alternate access method.

 A file with any other combination of alternate access methods is
 marked with a `+' character.

See "man getfacl" and "man 5 acl" for more information on ACLs.

I can only agree that O'Reilly books are well worth the price of
admission.  

As for the backup schemes / plans (which I can only assume are in that
book, as I've not personally read it yet), I favor a 3-2-1 setup.

 - 3 copies (original, backup, backup of the backup)
 - 2 mediums (HDD & something else - right now optical ... though I
   really need to change that)
 - 1 offiite

Don't forget that "if you don't have a tested backup, you don't have
a backup."

Currently, the system here is

 - every PC has a cronjob backing up $HOME to a central "server" (read -
   repurposed PC with decent WD drives), just an rsync script that runs
   daily.
 - /path/to/backups/$user/Documents/ is tar'd weekly and burned to disc.
 - discs are copied, and taken to parents' place.  "Rolling Updates" are
   performed there (as the CD case / binder thing (see: [1]) is already
   full, take oldest set of discs, replace with the newest, repeat til
   full again, then start over at the beginning).

Re: Black screen after "UEFI Installer menu"

2017-03-13 Thread Kostiantyn Ponomarenko

My PC has only one integrated video card from Intel Core-i7 CPU.
If I am not mistaken the driver for this GPU is integrated into linux kernel.
Anyways I tried using this netinstall image with integrated
proprietary firmware and that didn't succeed.
Whatever boot option I choose from "Debian UEFI Installer menu", I see
black screen only.
I suspect that the grub config is missing some options.

Any other thoughts?
Thank you,

https://www.debian.org/doc/manuals/debian-reference/ch05.fr.html#_the_wireless_lan_interface_with_wpa_wpa2

le premier lien parle des gestionnaires de connexion graphiques (voire
texte) en omettant connman et mentionne les conflits que tu peux

(dans ton cas wicd) et utilises aussi les anciennes méthodes...
... l'une de ces méthodes (celle que tu cherches à utiliser) étant
détaillée dans le deuxième lien.

et à partir du moment où tu cherches à utiliser du WPA, tu utilises
systématiquement une commande ou une bibliothèque fournie par le paquet
wpasupplicant, soi directement en ligne de commande, soit au travers du
fichier /etc/network/interfaces soit au travers d'un gestionnaire de
connexion.

pour résumer si tu veux utiliser wicd tu ne laisses qu'un squelette dans
/etc/network/interfaces et si tu souhaites utiliser
/etc/network/interfaces tu vires ou tu désactives wicd

A while ago I installed Sparky Linux on a cheap laptop, because it was
the only debian based distro I could find that would boot into that
stupid 32-bit uefi thing. Although I cannot say that I really need them,
the few Sparky-specific "extras" seem sound to me and the default
configuration also seems sane, as far as I have tried everything seems
to work well.

I have back-up'd my system with doing cp -a once from a live system to
copy my installation to an usb drive, then wrote a small script that
checks for the presence of that usb drive each time I shut down the
machine and, if it is connected, uses rsync to keep the backup up to
date. Probably this is not the "professional" way to handle backups, but
is has proven very handy a few times when I had thoroughly destroyed my
system. Just start a live system again, cp -a back the whole affair and
reboot. Always worked fine for me.

So having evangelised file-level copies a few times in this thread, I found
myself wondering if I would have been better off with imaging this very
weekend. Copying a 2.1T filesystem from an internal SATA2 disk to an external
one (my regular backup drive to my once-a-month, lives off-site one) via USB3
took nearly 48 hours via "rsync -a", and the destination ended up bigger,
possibly because one or more of the backups on the source had been using some
kind of hardlink de-dupe (I've ranted about hardlink trees being a problem in
various backup topics on -user, too...) and I didn't think to supply -S to
rsync.

The real test will be how long an incremental catch-up will take in the future.

Install Octave and write your own. It's only a few lines of Octave code 
to implement forward calculation, back propagation, the cost function 
and the derivative terms for gradient descent or similar.

Total well under 50 lines of code and you'll be done. And far better off 
for understanding exactly what your system is doing.

A bunch of optional packages as well as the base packages are packaged 
for Debian, but you can get a highly functional installation just doing 
aptitude install octave
