That works!  I used the amd64 “alpha5” image. I had to install the non-free

I do not follow Linux kernel development.  Apparently, people wanted

 I can only wonder how much complexity and KLOC are required (overall

AFAIK over-provisioning has no effect on longevity -- longevity is
proportional to total number of cells times rated erase/ write cycles
per cell divided by write throughput.


But, over-provisioning can improve write performance:

https://en.wikipedia.org/wiki/Write_amplification#Over-provisioning


Effective longevity depends on the number of times a block is
erased and written to. You can reduce that over the course of an
SSD's lifetime by limiting the space you think you have
available.

From the article you cited:

"Over-provisioning often takes away from user capacity, either
temporarily or permanently, but it gives back reduced write
amplification, increased endurance, and increased performance."

Increased endurance is increased longevity.


SSD manufacturers taking away part of the capacity and then telling us 
the drive has increased endurance measured against the reduced size is 
marketing speak.  (Similar rant for kB, MB, GB, etc..)



I use the term "over-provisioning" in the context of this mailing list 
-- e.g. what we can do as Debian users (and system administrators):


"Furthermore, if any SSD is set up with an overall partitioning layout 
smaller than 100% of the available space, that unpartitioned space will 
be automatically used by the SSD as over-provisioning as well."



Whether you partition the first 90% of an SSD and write X blocks at 
random intervals over some time period T, or partition 100% and do the 
same, the number of Program/ Erase (P/E) cycles will be the same.  (But 
the timing/ performance of clustered writes may differ.)  When X gets 
large enough, the drive will eventually fail.  I would call that X the 
endurance of the drive.  (Intel converts it to a MTBF of 1,200,000 hours 
for my Series 520 SSD's.)



So, over-provisioning *by Debian users* has no effect on longevity.

One of the things I do with an SSD is turn down "swappiness" to a 
minimum.

In /etc/sysctl.d/custom.conf

I put the following lines:

vm.swappiness = 0
vm.vfs_cache_pressure = 40
vm.dirty_background_ratio = 10
vm.dirty_ratio = 40

There are also a bunch of networking defaults for IPv4 and v6 for 
security and simplicity, but this is about SSD wear and swap space. A 
swap partition that is simply never written to never wears out.

I also put in ramdisk options for /tmp in /etc/fstab in order to 
reduce disk writes.

Unfortunately the various chips supported by e1000e are all subtly
different and each new chip seems to need extra code in the driver. 
Debian 9 still has Linux 4.9 and we haven't backported those driver
changes.

There is supposed to be an optional installer build that uses a newer
kernel version, but that hasn't officially happened yet.

At this point you might be better off using the alpha release of the
installer for Debian 10 "buster".

That is also my understanding and matches many articles advising how to
choose the best enterprise SSD for a particular workload. However, I
know that SSDs are a lot more "black box" than your typical HDD so I
think especially with consumer devices it could be hard to generalise
and reason about. At that level the device specs often do not specify
numbers for "terabytes written" or "drive writes per day".

It can also be surprising sometimes how little is written. For example,
I have some servers with flash memory for their operating system
install, with data on other storage:

https://www.supermicro.com/products/nfo/SATADOM.cfm

At the 16GB capacity these offer only 17TB of writes over 5 years and I
was a bit worried, so I was thinking of spending some effort making sure
that things which are regularly doing writes do so to a RAM disk
instead.

Luckily there's a SMART attribute (241) you can use to tell how much has
been written to the drive to date and when I checked that I found the
servers were typically writing only ~14GiB per month. So that would take
about 100 years to reach 17TB! Of course, the 5 year warranty covers
other factors too.

It all depends on use case, as clearly there are uses that are
write-intensive which would burn through 17TB in a matter of hours. I do
not put swap on these devices. Measuring is still essential in my view,
but things are indeed a lot easier than they were a decade ago.

Andy

In the absence of trim, restricting the logical capacity of the drive 
ensures a larger pool of cells known to the drive to be unused and 
available for wear leveling. Otherwise, if you write to a cell the drive 
has to always preserve the data in that cell even if you later erase the 
file you wrote there (because the drive doesn't know it was erased).  
This is essentially what the drive manufacturers do: they build a drive 
with capacity N but sell it as N-S where S is the amount of spare 
capacity held in reserve for wear leveling and to allow for cells to be 
removed from service as they reach end of life. In general, the more 
expensive the drive, the more it is overprovisioned to increase the 
longevity of the device.


On modern SSDs in light duty the difference is probably negligeable, 
especially if you occasionally fstrim to communicate how much of the 
drive is actually unused.

Re: Installer can't find network interface on Intel NUC BOXNUC8i3BEH1

I'm not sure if it's the exact same case but I had the same issue with a
more recent motherboard. Debian failed to detect the network card with the
E1000 drivers.

I tried an iso with the non free repo without success.

A base Ubuntu iso install was able to detect and configure the network

I'll see if I can find the adapter version. It was an Intel based adapter.

A swap partition is faster than a swap file.


Backing up, archiving, imaging, restoring, etc., swap files is
wasteful, but modifying those operations to exclude/ regenerate swap
files adds complexity (and risk).


In my SOHO environment, all my machines have a single system drive and
my bulk data is in a file server.  When I first started using SSD's and
USB flash drives as system drives, I was worried about swap wearing out
the drive.  So, I tried running without swap.  This worked until
memory got low, then the machines crashed.  So, I added memory and
reinstalled with 1 GB swap partitions.

I’m trying to install Debian Stretch on it

I made a bootable USB stick the usual way with dd to copy the iso to the stick. 
 It boots fine and loads some preliminary stuff.  When it gets to trying to

with a long list of network drivers for me to choose from.

aborted the installation.  On a hunch, I then tried to install Ubuntu 
(ubuntu-mate-18.04-desktop-amd64.iso) and that works fine.  The network comes 
up automatically.

So, on Ubuntu, I typed “lspci -v” and searched the output for the network 
interface.  It says that the driver installed for that interface is “e1000e”.  
A quick check on a working Stretch system shows that the e1000e driver *is*

Thank you! That's a pretty good explanation. Had your explanation been in

That's kind of my thinking also.

It is my understanding that NetworkManager doesn't try to manage interfaces
that are configured in /etc/network/interfaces. I think I kind of took that
to mean that "interfaces" was deprecated, just as the init-script system is
usable with systemd although deprecated.

Following that [wrong?] thinking, I'd think that the "canonical" tools for
network configuration would be NetworkManagerDE (NM) everywhere, but I
think I'm learning that it's ifupdown if you're not running X/, NM
otherwise.

Which, as pointed out above, is kind of the conclusion I'm coming to. I was
just hoping there was some documentation that explains this, instead of the

an incorrect piece from a 11-year old post except if Condition A exists,

It's not being phased out, at least to my knowledge.

There are, unfortunately, at least three competing ways to configure
network interfaces in Debian: /etc/network/interfaces, NetworkManager,
and systemd-networkd.

I know nothing about systemd-networkd, except that it is disabled by
default, so I won't discuss that.  Someone else may feel free to talk
about it.

The other two are able to work in tandem.  Any interface definition
in the /etc/network/interfaces file is authoritative and exclusive.
NetworkManager will not touch that interface.

If NetworkManager isn't installed, then other interfaces not mentioned
in /e/n/i will simply be left unconfigured.  If NM is installed, then
it will take control of any interfaces not configured by /e/n/i.

NM is not installed by default with just the "Standard" task, but it
*is* installed as a dependency of some, or perhaps all, of the desktop
environment tasks.

As far as I know, this is not new behavior; Debian has worked this way
for at least a few releases.  You may think the handbook is "out of date",
and perhaps it is for some things, but not for this one.

"ifupdown" is indeed installed:

root@server-1:~# apt list ifupdown
Listing... Done
ifupdown/stable,now 0.8.19 amd64 [installed]

So you're right; I must've been confusing that package with "ifconfig".

I think this must've been my problem; I must've edited the interfaces file
before downing the interface, which confused the system. It works as
expected when I do it in the sequence you present below:

auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug enp0s31f6

But, as mentioned, if I "ifdown enp0s3", then make the above change, then
"ifup enpos3", I have working network. So this method you provide works;
thanks! (The other troubleshooting questions you asked, I'm bypassing, as
the basic problem has been solved.)

Again, thanks for getting me beyond my snag!

If there's only 1 current pending sector it could be difficult to get a

and are (*should*) be capable to handle a few defect sectors. It doesn't

Yes, I've seen this too a couple of months ago on a remote NAS server. I
probably had the same reaction as you: I couldn't believe it. Especially as
the Current_Pending_Sector went to 0 and Reallocated_Sectors and
Offline_Uncorrectable staid at the same value as before, too.

Continuously monitor your drive's SMART values and (if possible) store the
results in a database (RRD, Timeseries DB, you name it) to create graphs
from the values. You can use the check_smart.pl monitoring plugin as an
examle. This will show you if the number of defect sectors increase or if
they stay steady. If the bad sectors increase, it's just a matter of time
until the drive physically fails. You can see an example of such a graph
(rrd in this case) with increasing bad sectors over 5 weeks here:
https://www.claudiokuenzler.com/blog/469/multiple-several-ways-monitor-physical-hard-drive-disk

As helpful as SMART is, never rely 100% on it, as drives may also fail
without any bad values in SMART.

Re: Bug with soft raid?

[Claudio Kuenzler]

Hello Steve,

As some of the other responders already said, check your drives' SMART
values.
But a disk may fail without any indication in the SMART table. I've seen
this a couple of years ago and documented it here:
https://www.claudiokuenzler.com/blog/301/disk-failure-not-detected-by-smart-ata1-failed-command
The errors you've seen are also kind of similar as the ones I saw (although
there are a couple of years in between, so Kernel messages might be a bit
different now).

Long story short: It was indeed a defect hard drive causing the problems
(and log entries).

A captive portal cannot redirect HTTPS requests.  I went around this
merry-go-round for some time before I figured it out.  What you need
is to go to a URL that won't redirect to HTTPS.  When I'm trying to
use a public hotspot, I go to a URL that I know won't redirect.
The captive portal kicks in, I do my login, and away I go.

A motel I stayed in last week actually had a note in their information
package telling Apple users to go to the motel's own home page (which
doesn't use HTTPS) before trying to do anything else.  So it's a known
problem - and one which the Evil Empire's browsers apparently manage
to circumvent somehow.

I'm using Seamonkey, BTW.

Perhaps they spell deprecate differently, but I can only find one
occurrence of the word, on page 224, referring to SSL.

I can only find three references to ifupdown (pp. 150, 383, 396),
none making any judgment on its use.

It's interesting that many people seem to think that networking
behaves like a daemon, where you can just change the configuration
file and then signal the daemon to reread the new file.

Perhaps there's something to be said for ifup copying more of its
state, eg the file contents, into /run/network so that ifdown
knows what ifup did.

  http://neverssl.com/

  Is one site I have bookmarked.  To be honest any "big" site you've
 not visitted before is probably OK.  (i.e. So you don't have a cached
 HST setting, which would make a redirect to the TLS-version.)

kmail - just a little problem

[Hans]

Hi folks, 

I am running into a little problem with kmail in plasma.

The problem is, that the column on the very left side (the one where the 
folders like "kmail-folder" are shown)  with the the definition "name" is very, 
very big (more than 4000 pixels wide). But I can not get it smaller, and there 
appeared a scrollbar below. 

I found no way to get rid of this and get the column smaller. It cannot be 
shifted in any way. If I add the other columns like "unread", "size" and 
"general", those can be made smaller and wider.

Any idea, how this behaviour appeared and how I can get rid of this?

Thank you for reading this message and for any help.

Best regards

It's better if that is *not* a correct address. What we want is
for the browser to make a request that won't be https, so that
the router can hijack it to redirect to the login hotspot.

I don't think one can assume that that's the correct address.
You're better off trying to connect to the router, so look
at the output of   ip r   for the appropriate address (default).

Re: Conseils sur la mise à jour d'application maison développée avec Django

Le 12/02/19 à 14:34, Olivier  a écrit :
> Avez-vous des conseils pour que les changements de version s'opèrent en

Si tu prévois des évolutions du schéma de données, il faut impérativement
gérer des scripts d'updates.

Tu peux faire
- tu coupes
- tu passe ton script de mise à jour de la structure et déploie tes fichiers
- tu redémarres avec la nouvelle version

Mais souvent on coupe pas et ça se fait au démarrage de l'application :
- déployer les nouveaux fichiers de l'application
- lancer un reload qui devra gérer les étapes suivantes :

- je regarde dans la base de données quelle est le dernier update appliqué
- je regarde dans le dossier d'updates si y'en a un plus récent à appliquer
- si oui je le lance et quand il a fini je repars au début
- sinon je démarre vraiment l'application et je peux commencer à répondre
  aux requêtes 

Pour limiter les coupures sur des applis avec de grosses bases, on peut
gérer la notion de mises à jour non bloquantes (par ex un update qui va
ajouter un champ calculé, mais dont l'absence ne plante pas l'appli), tu
peux gérer cet aspect bloquant / non bloquant dans les étapes décrites
ci-dessus (si tous les updates qui restent à appliquer sont non-bloquants
tu peux démarrer quand même et les lancer en tâche de fond, mais en
séquentiel).

Pour la mise à jour sans modif de schéma, en général c'est rsync puis
redémarrage du serveur applicatif. Je suppose que django ne relit les
fichiers qu'au démarrage ou à leur premier appel et que ça pose pas de pb
si le rsync dure qq secondes.

The one that says: "Debian 7, 8, & 9 require the installation of

Looks like it needs non-free firmware (firmware-atheros) - until buster.

It's not your browser; it's the public hotspot, which is trying

The installer doesn't have that option, but if you tell it to go

firefox does not redirect to login page

[Flo]

Dear All,

I have an old laptop which I set up yesterday. And since it's old I only
install the packages I need.

Today I realized that I cannot login into an public hotspot.

Up to now it worked in a way that I got redirected to the login page
where I had to click on the connect button. This does not happen now.

It just says it cannot find the webpage.

What package is necessary to make firefox able to redirect me to the
login page? What do I need to install?

Any help is appreciated.

Thanks a lot.

When I open a message on a mailing list or newsgroup and see nothing but
quoted text I usually just move on to the next message.  On the other
hand I find top-posted responses that remain cryptic until I've scrolled
through a hundred lines of mostly-irrelevant quoted text a bit
irritating too.

It's better not to post "Thanks" to a busy mailing list.  If you must do
so please put "Thanks" in the subject line.

The ifupdown package has priority "important" and, as far as I know, it
is installed by default.

You might be confusing it with "ifconfig", which is in the net-tools
package, which is *not* installed by default in stretch (a departure from
previous releases).

OK, let's back up a second.

What was in the /etc/network/interfaces file *before* you edited it?  Was
it configured for DHCP?  If so, you should bring the interface down *before*
you edit the file, so that ifdown knows there is a DHCP client daemon
running associated with this interface, that it should kill.

If you're currently configured for DHCP, and you edit the file before
bringing down the interface, the DHCP client daemon will continue running
(ifdown doesn't know about it, because you changed the file that would
have told it).  Which means you would have to kill the DHCP client daemon
yourself, either manually, or by rebooting.

So, the proper sequence is:

1) ifdown interfacename
2) edit /etc/network/interfaces
3) ifup interfacename

What's in the /etc/network/interfaces file now?

What do "ip link" and "ip addr" tell you?

Are there any relevant errors in dmesg?

What output (if any) do you get from "ifup interfacename"?

Are there any useful messages in "systemctl status networking.service"
or in "journalctl -u networking.service"?

IMO, it's ok for disk devices to develop unreadable blocks (bad blocks),
as long as they don't progress.
Internal firmware of the disk takes care of bad blocks, marks them
internally and reallocates them. (makes sure that next read\write
request to that bad block will be redirected to a safe block)
When internal list of bad blocks and reallocations will be full,
firmware will mark HDD as failed in SMART.

As capacity of modern HDDs gets bigger and surface density of blocks
increases, so does margin for error of faulty blocks. It is rare for a
large disk to not have them, despite the fact that every disk was
scanned and faulty regions remapped beforehand during manufacturing
process at the factory.
HDDs that developed bad blocks should be monitored for progression and
replaced if bad blocks began to appear frequently. You can get one bad
block in 5 years or 30 in a few days and there is no guarantee that
brand new drive won't have bad blocks.

Most hardware RAID controllers perform automatic full surface scans to
ensure data consistency (also could be called "patrol scans") and mark
HDDs as "Expected to Fail Soon" to warn user.
You have to backup your data regularly and in case of large RAID5/6
level arrays you should have at least one Hot Spare drive available in
your enclosure at all times.
Precautions are almost the same for software RAID, but more difficult to
setup.

Sometimes disk sectors go bad. When the disk detects that, it
reads whatever it can and writes it somewhere else.

You can expect the number to be reset to zero either on repair
or after a power-cycle.

A small number in CPS is fine. If it starts going up, or the
reallocated sector count starts increasing, you might have an 
impending disaster.

I vary the use of top-posting and "bottom"-posting depending on circumstances.

For thanks and similar, top posting works very well.  In dealing with some 
other groups or "types" of people, top-posting works well (because, in many 
cases, it is what they expect or are used to).

On lists that prefer "bottom"-posting, I try to ususally comply, with 
exceptions.

In either case, I advocate quite extensive eliding of irrelevant parts of a 
post.

Hello folks:

Again -- fussing with a full (not from a live .iso) 9.7 install; the 
Debian GUI installer is suggesting a Swap partition on a Kingston SSD.



#1 Given that it's not great to pound the same area of a SSD with 
writes; is it indeed still best practice to go with a swap partition on 
a SSD rather than a swap FILE?


(Or is this a legacy spinning hard disk install suggestion?)


#2 How DO you get the installer to go with a Swap FILE?

Just delete that recommended Swap partition during the install?


I looked; but did not run across any best practice docs for Swap on SSD.

Re: install-parties a escoles, qui s'anima?!

[Roger]

Hola bones, soc nou per aqui, de fet m'he subscrit per comentar aquest
tema i també perque soc usuari de Debian des de ja fa forces anys.

Respecte aquest tema, doncs ho trobo molt bona idea i a la meva zona,
Valls i l'Alt Camp, trobariem forces escoles interessades. De fet, ja
fa temps que col·laboro amb un grup de Programari Lliure de Valls
(Hacklabvalls), i fem installs partys de forma periòdica amb un èxit
raonable (sobretot en les primeres edicions). A més, actualment hem
recuperat varies torres i portàtils (molt vells) amb Linkat i Linkat
lleugera per a una escola propera. Doncs bé, estic i estem oberts o
col·laborar amb el que convingui :-) També tenim força material
recuperat per revifar maquines velles (Ram, pci's, processadors, fonts,
discs, etc), ho comento per si algú pot necessitar quelcom..

Ja he vist que per la llista de Caliu, han comentat de que aquest tema
el mouran a través del CRP's, doncs bé estaré atent a lo que diguin...

Percert gent de Salou, no crec que ens coneguem, però estaria bé potser
algun dia trobar-nos, o qui sap si fer quelcom conjunt ;-)

Salut,

iptables issue with ASP.Net Core Port 5000

[Patrick Kirk]

Hi all,

I have a simple asp.net core site that runs with Postgres which works 
fine if I login as root and set it to run on port 80.  SSL is done by 
cloudflare.  I would prefer to use nginx or at least have an iptable 
rule to redirect the port 80 traffic.  Both have the same failure so for 
now I am trying with iptables.


I don't believe this is an issue with asp.net but the line I use to set 
ports is:


public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args).UseUrls("http://localhost:5000;, 
"http://*:80;)

.UseStartup();

To run the program on port 80, I have to run as root which I want to get 
away from.  So I remove the port 80 from Program.cs and then run the 
program.  Output of nmap is:


Starting Nmap 7.40 ( https://nmap.org ) at 2019-02-13 10:35 UTC
Nmap scan report for localhost (127.0.0.1)
Host is up (0.080s latency).
Not shown: 997 closed ports
PORT STATE SERVICE
22/tcp   open  ssh
5000/tcp open  upnp
5432/tcp open  postgresql

If I try the iptables route the command I use is:

 iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 5000

This works fine for Lynx http://localhost but for my url I get

"Alert!: HTTP/1.1 521 Origin Down"

If I try to use nginx, which I believe is configured correctly, I get 
the exact same issue.


Has anyone any idea what's wrong with my setup?

Patrick

Réseau hertzien et Debian

[kaliderus]

Le bonjour la liste,

Je cogite sur comment mettre en oeuvre une liaison entre 2 habitations
sur réseau hertzien.
La distance point à point est d'environs 1,3km avec obstacles (arbres,
et quelques maisons).
Connaissez vous des équipements ad-hoc qui permettent cette topologie ?

Ce n'est pas un amplificateur wifi que je recherche mais une solution
autonome professionnelle, qui me permette entre autres de chiffrer les
échanges (et qui  demande une licence à l'ANFR).

Si vous avez quelques références j'apprécierai.

Merci la liste.

P2V Debian 9 with VMware Converter

[Adam Weremczuk]

Hi all,

I persistently get "The destination does not support EFI firmware" .

Apparently the latest Converter doesn't support Debian 9 (yet?).

More details on my issue here: 
https://communities.vmware.com/message/2837600


Has anybody had success tricking Converter to perform a migration?

Any other P2V tools you would recommend?

Thanks,
Adam
