Nonsense? I think the lines illustrate the issue to the
experienced eye and in fact, it did, so that Pierre-Elliott
spotted the issue (I tell it in a second).

I had told I would use vim to edit the file... but I had been wrong!
The machine I SSH'd to in fact was not a machine, but rather
a container, and the network configured by the virtualisation
environment! That is what changes the IP. The container op
made an error in the IP and I was the unfortunate one just
arriving in time :)

Thank you for your help! Yes, good idea!

I couldn't see the cause in the whole file system, and as
Thankfully Pierre-Elliott Bécue correctly saw from a wide
distance that this is because - it is in fact not in the
file system. But outside. Namely a virtualisation
environment set it into a container (the machine
actually is "just" a container).

Yes, but I found nothing in any logfile, the IP did not appear anywhere
in the file system and I had no idea what to do...

It turned out the machine actually is a virtualisation container
and the infrastructure configures the IP (which was incorrectly set in the
virtualization web GUI). Well, and I didn't see this, but
fortunately Pierre-Elliott Bécue (from this list) saw it instead.

Yes, thanks, sure, I know. I just wanted to show that it does change
automagically at reboot (it is written by virtualisation environment
when the container is being started). The stanza was correct,
just gateway IP was wrong, because someome made an error
in the container configuration and it just so happend that it was
my little foot where it fell onto...

THIS! (OMG why didn't I see this! Thank you!!)

ohh thanks so much for your quick reply, my "machine" indeed is a
Proxmox-Container, and someone made a typo in the container settings,
so Proxmox configures the container accordingly.
For other files, like resolv.conf, Proxmox adds "# --- BEGIN PVE ---"
lines, but not in interfaces.

Only in the unlikely case that both RNGD and SCDrand turn out unsuitable
somehow. Writing and compiling a daemon is no less work than compiling
an already written daemon.

RNGD 6 actually uses OpenSC's libp11, where it calls the function
PKCS11_generate_random, which in turn calls the PKCS #11 function
C_GenerateRandom.

Tu ne peux pas sinon le FTP répondra directement à l'IP d'origine. Or tu

Au lieu du NAT, squid peut faire le travail avec en plus filtrage, cache

Is this actually Debian?

I have vague memories of someone else asking something like this
before, and at the time I wasn't aware of any software packaged in
Debian that alters the user's /etc/network/interfaces file. I think
in that case it turned out to not actually be Debian.

I also think that there is some Debian packaging rule about one
package not altering the config file of another package unless by
co-operation between the maintainers, so if this does actually turn
out to be Debian there might be bugs to report.

Thanks,
Andy

Re: debian12: something destroys /etc/network/interfaces at boot

[Pierre-Elliott Bécue]

As it's a PVE kernel I guess you rely on Proxmox.

*Theoretically*, Proxmox VE uses /etc/network/interfaces.new to apply
its config and potential manual changes made by an administrator
(changes that should be applied afterwards via ifreload).

I'd wonder whether this mechanism is not the cause if your troubles.

So then the question is *which* of the many different subsystems is in
use to set the system's default gateway.  It might be coming from /e/n/i
or from NetworkManager or from systemd-networkd or others.

See, that's not useful.  That's not how this file is structured.  It's
NOT just a series of independent lines.

We would need to see the entire /e/n/i file to know which interface
that gateway definition is associated with, and so on.

A gateway definition on an interface that isn't managed by /e/n/i (ifupdown)
will do nothing at all.  For example, you might have an eno1 definition
which includes a gateway line, but which does *not* have an "auto eno1"
line to activate it -- in which case the interface might be managed by
NetworkManager instead, or something else.

debian12: something destroys /etc/network/interfaces at boot

Hi,

I changed a gateway on a remote site using /etc/network/interfaces by
changing gateway. However, at reboot some old gateway IP reappears. I
really hate when some magic knows better than an explicitly set value.
What happens here? How can I get rid of this? It is 100% reproducible.

I have no clue where the wrong 2.43 comes from.

Reverse ftp proxy

[BERTRAND Joël]

Bonjour à tous,

J'essaie d'installer sans succès un reverse ftp proxy et je me demande
si ce que je cherche à faire est possible.

Configuration :

IP publique --- serveur frontal Linux --- LAN --- serveur FTP anonyme

L'IP publique est propre au serveur FTP que je ne veux pas mettre en
frontal sur internet (je suis contraint d'y laisser un telnet ouvert).

Je peux donc configurer une IP virtuelle sur le port WAN du serveur
Linux et tout balancer avec du NAT vers le serveur FTP. Mais, à ce
moment, dans les logs du serveur FTP, je ne vois que l'adresse IP du
serveur Linux. Or j'aurais besoin de logguer les vraies IP pour les
transactions.

Comment faire ? Si toutefois il est possible de faire... Au pire, des
logs côté serveur Linux pourraient m'aller, mais si ce serait compliqué
à gérer.

Deuxième question : le serveur FTP est un OS un peu spécial qui ne
comprend pas IPv6. Est-il possible de rediriger IPv6 sur du V4 de

No, I was wondering about the server hardware. I would be surprised to

Yeah, I've had to do that in the past. You will also (probably) need
to write a systemd unit file or two.

For what you want to do, and if I am parsing it correctly... I would
write a daemon in C to collect the entropy from the source, then
extract the entropy from the bytes, and then insert the entropy into
the system's random number generator. For entropy extraction, take a
look at HKDF and Krawczyk's paper. Krawczyk does a good job of cleanly
separating entropy extraction from later stage key expansion.

The part about extracting the entropy from the source would use
OpenSSL or GnuPG. I believe you would compile and link to OpenSSL's
libcrypto.{a|so}, or GnuPG's libgcrypt.{a|so}. Since this is a daemon
and not a driver, I believe you can use the shared objects.

I eat my own dog food. I've done similar in the past with both an
EntropyKey and custom on-board generator for a MIPS Creator CI-20 with
the jz4780-rng. For the EntropyKey, I did not even bother decrypting
the stream. I stuffed the encrypted stream right into /dev/random,
because the amount of entropy does not change regardless of the
formatting (encrypted vs unencrypted).

And you may find this interesting... Debian suffers entropy depletion
on /dev/random and can hang components that use it, including
/dev/urandom. It is easy for a userland process to do. All you need is
a stock Debian system _without_ an entropy gatherer like Haveged. Have
your program perform a big read on /dev/random with O_NONBLOCK. The
kernel will return every last bit of entropy it has, and then start
blocking processes. The only way to recover in reasonable time is to
run a daemon like Haveged. I reported it to the devs several years
ago, but there was no interest in fixing it.

OT: Lista de correo sobre HARDWARE

[Eduardo Jorge Gil Michelena]

Estimada gente:

Disculpen el OT...
¿Conocen alguna lista de correos o foro web sobre Hardware?

Antes había muchos pero ahora... parece que han desaparecido o por lo menos los 
que yo conocía.
Y en la WEB... la información que suelo buscar seguramente debe estar pero... 
con tanta página y sitio con información pobre y claramente comercial, es 
difícil encontrar algo técnico que seguramente debe estar... como lo puede 
estar una aguja en un pajar.

Saludos.

Some web pages don't load completely unless you scroll down them,
whereupon more of the page is loaded. Even if you press End, you may
not get the whole page loaded. One method of completion is to
repeatedly press End and PageUp until no more content appears
(or you observe some sort of bottom-of-page indication).

You'll recognise this if you shop with Kroger™/Dillons™/Fry's™
( in the US).

Ctrl-R is of no help: it can merely reload as much of the page as has
been visited so far. So there is some method in their madness (for
this one step—I don't know about the rest).

You seem to have mislaid your first reply to Alexander, at:

which appears to show that the drive was a dud 64GB disk, and

At a glance, the first warning looks like it might be the
unsophisticated concatenation and substitution of paths,
without regard for either leading and trailing delimiters
or filename extensions:

  null plus /usr/lib/php/20190902/mysqli.so

  /usr/lib/php/20190902/ plus /usr/lib/php/20190902/mysqli.so plus .so
  ---
substitution ↗

The second warning looks more significant, but mysqli is outside my
area of knowledge. Nonetheless, "mysqli" was seen in the last line,
though without any context: grep might be helped along by -A and -B.

Cheers,
David.

I figure it can be used with devices it supports even if there are some
other devices it doesn't support – but it looks like I'd have to build
it from source myself.

This job requires a daemon. OpenSSL is a library. Or do you mean its
command-line tool? So how would I tell that to fetch random data
through PKCS #11?

GnuPG at least has a daemon called scdaemon. Is that what you mean? So
how would I tell that to fetch random data through PKCS #11 and write
to /dev/random?

Re: Debian 11 PHP 7.4 – Mysql 8 - Can’t get Mysqli_connect to work

[Bernard]

I have progressed a little in my trials.

mysqli.so still shows the previously described problems, and I thought 
that this was responsible of the fact that mysqli functions were 
apparently discarded in the test programs I wrote.


I discovered that this was due to errors I made in the php program. The 
errors in the script being corrected, mysqli_connect, mysqli_select_db, 
mysqli_query... now do operate... despite the errors concerning 
mysqli.so that I discovered when running the tests which are proposed by 
'baeldung.com'

|$ php -m | grep mysqli|

"If the MySQLi extension is enabled, we’ll see /mysqli/ in the output. 
Otherwise, the output will be empty."

Next format partition to ext4 filesystem:

Next mount the filesystem:
 $ sudo mkdir /mnt/disktest check
 $ sudo mount /dev/sdX1 /mnt/disktest check

Next create reference 1GB file filled with dummy data:
 $ cd /mnt/disktest check
 $ sudo fallocate -l 1G ./reftestfile check
 $ sudo badblocks -w -s -t random ./reftestfile check

Now we can use script to create 1830 1GB files and check their checksum:
 $ for i in $(seq 1830); do sudo dd if="./reftestfile" 
of="./testfile${i}" status=none; md5sum -b "./testfile${i}" ;done


This procedure will take a very long time to complete. "md5sum" will 
output the checksum for each file and they should be equal to 
checksum of "reftestfile":

 $ md5sum -b ./reftestfile

Got a problem Alexander:
I had to put the script someplace else. So I put it in my private 
/home/gene/bin as disktest.txt with nano. couldn't find it.

But:
gene@coyote:/mnt/disktest$ sudo /home/gene/bin/disktest.txt
sudo: /home/gene/bin/disktest.txt: command not found
If you put that 'for' loop one-liner inside, I think you forgot to make 
"/home/gene/bin/disktest.txt" executable:

     $ chmod +x /home/gene/bin/disktest.txt


And:
gene@coyote:/mnt/disktest$ ls /home/gene/bin/disktest.txt
/home/gene/bin/disktest.txt
So I think I found the problem with my script, ancient eyeballs can't 
tell the diff between () and{} so I fixed that but it still won't run 
or be killed. I don't care how big you've made the t-bird font, by the 
time you've read 2 more msgs, its back to about 6 point text.  Grrr.


So I fired up a root session of htop, found about 8 copies of dd 
showing and started killing them but cannot kill the last 2 in the D 
state.


And cannot find .disktest.txt running in a root htop and the2 copy's 
of dd can't be killall'd.



It's not possible for me to know what went wrong.
Have you created "reftestfile" inside "/mnt/disktest" directory?
How many "testfile*" files, if any, were created on the filesystem 
mounted at "/mnt/disktest"?

Was there anything relevant in the syslog about "sdm" drive after the test?
If you'd followed my instructions step by step, you'd end up inside 
"/mnt/disktest" directory and for the last step all you had to do is 
copy and paste that one-liner 'for' loop into the command line.
It's a long line and it really meant to be copied and pasted not typed 
by hand, and also to give you the idea of the process, so you could 
adjust it if needed.
I've tested it again on my computer and it worked as expected, 
synchronously created "testfiles" inside current directory and
