Looking up the MAC address in the name of that last interface the name
says it's from Realtek Semiconductor Corp so it seems unrelated to the
other Intel devices. Try looking at the output of 'dmesg' and look for
'Realtek' in the kernal log for a clue.

Do you have any other network devices plugged in, perhaps in USB port?
Possibly a wifi dongle. Also, a long shot, something could be
automagically configuring something like a phone or bluetooth device
for network use.

multiple network interfaces...and a ghost

[Peter Ehlert]

after a system update and a new kernel I rebooted.

all seemed fine but the network would not connect...
Debian Mate, network install, it just works and I never have messed with 
the settings.

not a clue what was going on.

long story short, messing around a live USB did log in fine.

I decided to try a fresh netinstall alongside and Boom:

===
multiple network interfaces

eno1: Intel Corporation Ethernet Connection (2) I218-LM
enp5s0: Intel Corporation 1210 Gigabit Network Connection
enx00e04c534458: Unknown Interface
===

the first two are old hat, I use eno1 and it just works.

bottom line I opened the Network Connections tool, found those three, 
none were selected.

I selected eno1 and all is good.

what about this mystery "Unknown"?
do I have a pending hardware failure?

From the peanut gallery: I disabled IPv6 quite some time ago.  I don't recall 
how I did it, but I might have that information in my notes, somewhere.

The reason that I disabled it (which might not be totally logical) is that in 
IPv4, I have always had my computers (and LAN) behind a NAT device.  

I could not find (in the searching I did) equivalent functionality for IPv6, so 
I disabled IPv6 in hopes of keeping my systems (fairly) secure.

I'm not sure that makes a lot of sense, and I'm sure [some | many | most | 
maybe almost all] will disagree, especially based on the 128(?)-bit address 
space in IPv6, but that was the reason I disabled IPv6.

If you expose a DNS server on port 53 then it's normal for bots out
on the Internet to scan to see if they can use it to resolve things.
Your DNS resolver is correctly set to disallow queries from
elsewhere.

Are you actually experiencing any breakage? If so, what?

First mistake: you should not be editing files in /lib/systemd/.
Instead copy the file to edit into /etc/systemd/, and edit it there. I
believe there is a systemd command that will do that for you if
necessary. The reason is that when an upgrade comes along, it will
stomp on any changes you have made in /lib/systemd/.

It looks like it is successfully configuring its command channel on
IPv4 (127.0.0.1#953), and unsuccessfully on IPv6 (::1#953). If you
don't care about IPv6, you can probably ignore that.

I don't see all of those messages on my bind9 installation's log. I am
running bind9   1:9.16.27-1~deb11u1

On Linux, a process that writes to a device that is not currently
mounted and therefore has no page cache will go into D state when
closing the associated file descriptor.

You can check for with this kind of command:

strace -ftttT sh -c "( dd if=/dev/urandom bs=1M count=0 seek=32000; cat 
/tmp/file ) > /dev/disk/by-label/CIGAES_R64"

Notice the time taken by the close(1).

If you naively run strace on cat itself, then you do not see anything,
because then strace itself is holding a copy of the file descriptor, and
it is strace that will go into D state.

I do not know where this behavior is documented, but I suspect it is
somewhere.

Sí, se hace así.
Una sola recomendación para facilitar la tarea:
En las distintas instalaciones, el usuario que acceda a los datos, debe 
tener el mismo nombre de usuario y mismo UID (Número de Identificación 
de Usuario).
Si no lo haces así, no es imposible acceder a los datos, pero trae 
dolores de cabeza.


Salvo que la partición "DATOS" esté en formato NTFS (Windows), la cual 
es intrínsicamente insegura e inestable desde Linux.

avahi-daemon allow/deny interfaces question

[Ram Ramesh]

Experts,

  I have a firewall machine built recently and it runs debian bullseye 
(v11). It has two ethernet interfaces - one internal ($intf) and one 
external ($extf). My external port runs dhclient to get its IP address 
and internal port runs dnsmasq to provide DNS service to 
internal/protected hosts. Usual iptables rules are established to 
prevent attack/entry into internal net from external net and allow 
proper internet access to internal net hosts.


  I had this system working fine (on an older machine) since debian 
5.0.7. I have not upgraded that machine as it is working fine. However 
that hardware is too old (10+ years) and I wanted to replace it with 
something more modern running latest OS and that is why I built the 
above machine.


 My old machine does not seem have avahi-daemon. So, it runs fine. 
However, my new machine has this daemon running which notices that 
$extif does not have much activity and disables it after some timeout 
idle time. I initially thought my firewall rules are suspect and was 
banging my head for a while adding extra rules for DHCPDISCOVER/REQUEST 
etc thinking that those are blocked. Today I noticed that my $extif is 
vanishing and /var/log/daemon.log shows some avahi-daemon messages about 
that interface being disabled/withdrawn or some such thing.


As a next step, I want to tell avahi-daemon that it should not work on 
that interface as it is not meant to be fooled around.  Do I use 
deny-interface $extif or allow-interface $intif only? Which is proper? 
Will doing one of these solve my problem of $extif vanishing from ifconfig?


If you think there is something else that I can do that is better, 
please let me know that too.


Much appreciate any help.

Please let me know if you need anything else that will help to resolve 
this problem.

And you got a warning for the wrongness.

So, you are wondering why it actually compiled correctly.  Best guess:
on Gentoo, you have the libpq-fe.h file in a different directory, which
is in the C++ compiler's search list.  Maybe there's a symlink.  In any
case, the -I/usr/include/postgresql-14 argument isn't needed on Gentoo.

If you really want to dig into it, start with something like
"locate libpq-fe.h" and see all of the places it appears.  Then see what
directories are in the compiler's search list, etc.

.
As a reminder, locate's database might be stale, so it is probably a 
good idea
to sudo updatedb before running locate, assuring then that it has an 
uptodate

database.  I think it does a weekly update, but if Igor is installing stuff
from the error messages, that is probably something he should be doing after

Normaal gebruik je in /etc/fstab geen UUID's van disks volgens mij.
Maar UUID's van filesystemen.

Het maakt dan niet uit welke disk het is.

Als je ext4 gebruikt, dan kun je achter het UUID komen met iets als:
tune2fs -l /dev/sdb8 | grep UUID

I looks like `pg_config --includedir` expanded to /usr/include/postgresql-14
and the compiler takes it for a linker file. (I assume it's a directory.)

So the lists of include directories generated by libtool differ.
On Gentoo:
  .
  /home/igor/dbhandler/libpostgres
  ..
  ../../dbinterface
On Debian
  .
  ../../libpostgres
  ..
  ../../dbinterface

On both the output of pg_config is not properly marked by -I.

Can it be that on Gentoo there is a file
  /home/igor/dbhandler/libpostgres/libpq-fe.h
?

--

Whatever, try to fix your Makefile.am by adding "-I". Like in

  libpostgres_la_CXXFLAGS = -D__WXGTK__ \
  -I../../dbinterface \
  -I`pg_config \
  --includedir`


Have a nice day :)

Re: Does Debian supports backticks in the Makefile?

igor@IgorReinCloud ~/dbhandler/Debug/libpostgres $ pg_config --includedir
/usr/include/postgresql-14
igor@IgorReinCloud ~/dbhandler/Debug/libpostgres $

No "-I" involved.

Based on the skimming I've done of this thread, my guess would be that
either the tooling in that environment behaves differently, or the
configuration in that environment (e.g. autotools output) has already
been run and on the Debian side the necessary commands to run it aren't
being issued.

Caio, bom dia!

Tive esse mesmo problema com um teclado que comprei que possui layout Mac... 
Até tentei usar algun programas de remap de tecla mas não funcionou como eu 
gostaria. :confused:
De qualquer forma, usa o layout "English (US, intl., with dead keys)" e ai pra 
usar o "Ç" você usa as teclas "Option"+"<".
O layout correto pra ele deveria ser o "English (US, international PC)", mas 
aparentemente esse layout não existe.

Note that pg_config does also support a --cflags option (there doesn't
appear to be a man page, at least not in Debian under the obvious name,
but see 'pg_config --help'); however, it's documented as providing not
the flags necessary to compile programs against the installed PostgreSQL
but rather the "CFLAGS value used when [the installed version of]
PostgreSQL was built".

In some cases those two things will be the same, but not necessarily in
all - and I fail to see how the latter is useful information to know,
except in a "trying to debug the installed PostgreSQL instance" sort of
scenario, which hardly seems like what pg_config would intuitively be
intended for.

You're misunderstanding my conclusions.  The backticks *do* work in the
end, since they're passed through to the shell, and the shell interprets
them the way the OP seems to want.

The missing -I is probably it.  It's interesting that pkg-config --cflags
and pg_config --includedir deviate in this way.

Together with Greg Wooledge's observation that "make"'s macro definition
does not interpret `...` as output of shell commands we already have
two reasons why that part of the Makefile should not work.

The riddle grows why it appears to work on Gentoo.

--

  info make
shows a "MAKE(P) POSIX Programmer's Manual" which explains that what i
perceive as variables are indeed macros. No mentioning is to see of any
shell-like properties.

The web has workarounds with GNU make:
  
https://stackoverflow.com/questions/10024279/how-to-use-shell-commands-in-makefile
This is confirmed by
  https://www.gnu.org/software/make/manual/html_node/Shell-Function.html

Alternatively i would try to hand over the "-I..." argument by an
environment variable.

But i guess the autotools way is to insert the desired arguments at
latest when ./configure creates Makefile from Makefile.in.
(Now we could need hearsay about how this is to be done ...)

This is a very good theory. It has to be "-I foo -I bar ...", AFAIR. The
current manual [1] is very clear on this, too.

Sharp eye :)

Note that this wouldn't happen with the very similar `pkg-config'. This
one prepends the `-I' to its output. o figure ;-)

On some of them, yes. The process is to flash a new BIOS, after
which the Chromebook is just a laptop. 

https://github.com/MrChromebox/SeaBIOS

I don't recommend this approach for general use machines: chromebooks
are generally sold with tiny flash disks, often unreplaceable. A 16 or
32GB flash disk will limit you severely.

As a limited use machine, though, it shouldn't be bad.

You're asking whether this works in a variable definition inside a
Makefile.  I'm assuming you're using GNU make.

Well, let's TEST IT AND SEE.  Shsh.


unicorn:~$ cd tmp
unicorn:~/tmp$ vi Makefile
unicorn:~/tmp$ cat Makefile
foo = abc `echo def` ghi

bar = jkl \
`echo \
mno` \
pqr

one:
echo $(foo)

two:
echo $(bar)
unicorn:~/tmp$ make one
echo abc `echo def` ghi
abc def ghi
unicorn:~/tmp$ make two
echo jkl `echo mno` pqr
jkl mno pqr
unicorn:~/tmp$ make --version | head -n1
GNU Make 4.3


So, what do we conclude from this?  The backticks are not expanded when
the make variable is defined.  They're included literally in the variable's
contents.  They get passed to the shell command that make executes, and
the shell interprets them as a command substitution.

On a personal note, I find this construction extremely ugly:

`pg_config \
--includedir`

I can't see any sensible reason why you would write a command
substitution this way, with the command's single argument on a separate
line from the command itself.  That's part of the reason why I tested it
separately in my demonstration.  The other part is that I thought,
perhaps, the command substitution might have been handled by make itself,
during the variable definition.  And if that were the case, then perhaps
splitting it across lines might have confused make, and caused it not to
work.

But as we saw in the test, it works the same either way.

Re: Does Debian supports backticks in the Makefile?

[Thomas Schmitt]

Hi,

how about this theory:

  https://gcc.gnu.org/onlinedocs/cpp/Invocation.html#Invocation
says

  "-I dir
 Add the directory dir to the list of directories to be searched
 for header files during preprocessing."

Note the the singular "dir", not "dirs".

In Igor Korot's Makefile.am we see

  libpostgres_la_CXXFLAGS = -D__WXGTK__ \
  -I../../dbinterface \
  `pg_config \
  --includedir`

which is supposed to a set the variable libpostgres_la_CXXFLAGS to

  -D__WXGTK__ -I../../dbinterface /usr/include/postgresql

It appears that an argument -I is missing before /usr/include/postgresql.



I tested with a small dummy program which does:
  #include "test1.h"
  #include "test2.h"
There are dummy header files:
  test/include/test_2_dir/test1.h
  test/include/test_2_dir/test2.h

Then i try
  cc -g -Itest/include/test_1_dir test/include/test_2_dir -o t t.c
which complains
  t.c:19:19: fatal error: test2.h: No such file or directory
   #include "test2.h"
 ^
  compilation terminated.
I.e. it does not mention the surplus argument test/include/test_2_dir
before it ends.

This run succeeds:
  cc -g -Itest/include/test_1_dir -Itest/include/test_2_dir -o t t.c



If my theory is right, then the question arises why it works with
Igor Korot's Gentoo installation.
man gcc proposes as suspects:

   CPATH
   C_INCLUDE_PATH
   CPLUS_INCLUDE_PATH
   OBJC_INCLUDE_PATH
   Each variable's value is a list of directories separated by a
   special character, much like PATH, in which to look for header
   files.


Have a nice day :)

Yep. That's why I think it makes sense to bisect the problem at the
`pg_config' point: is it delivering the correct compile flags? If
yes, look into the rest of configury, if not, try to fix pg_config.

Many possibilities there: wrong pg_config in $PATH, left over from
some attempt to self-compile PostgreSQL could be one. We just don't
know :)

There is some amount of cargo-cult in there. But it pays to try to

I think the compile line must be visible (in its expanded form) in the
build logs. I'd urge Igor to look out for it. And tell us, of course :)

Question is what Igor Korot is trying to compile.
If it is postgres itself or one of its helpers, then libpq-fe.h would
probably be one of the "header files of your own program".

We should rather look at the original post. ~:o)

Igor Korot wrote:

So the question is whether there is
  /usr/include/postgresql/libpq-fe.h
as should be if libpq-dev is installed (says apt-file).

If it is there, then the question is why it isn't found.
Besides the suspicion of Igor Korot, that `pg_config --includedir` would
not work, there is the possibility that libpostgres/Makefile.am was
not porperly converted to libpostgres/Makefile.in and then to
libpostgres/Makefile .

This is normally done by a script which calls autoconf and automake
to create Makefile.in. Later ./configure creates Makefile from Makefile.in.
In libisoburn the script has the name ./bootstrap and contains:
  aclocal -I .
  libtoolize --copy --force
  autoconf
  automake --foreign --add-missing --copy --include-deps
Don't ask me why. I inherited it in 2006 in the course of the libburn fork.
autotools usage worldwide is nearly completely driven by hearsay.


@ Igor Korot:
It would be interesting to see the effective compiler options (which the
make run seems to hide from the user) and whether the usage-ready
Makefile contains the lines

  libpostgres_la_CXXFLAGS = -D__WXGTK__ \
  -I../../dbinterface \
  `pg_config \
  --includedir`


Have a nice day :)

Yes, you're right. Thanks for the correction.

Re: Does Debian supports backticks in the Makefile?

Hi,

https://gcc.gnu.org/onlinedocs/cpp/Include-Syntax.html

  #include 
  This variant is used for system header files. It searches for a file
  named file in a standard list of system directories. You can prepend
  directories to this list with the -I option (see Invocation).

  #include "file"
  This variant is used for header files of your own program. It searches
  for a file named file first in the directory containing the current file,
  then in the quote directories and then the same directories used for
  . You can prepend directories to the list of quote directories
  with the -iquote option.

So "libpq-fe.h" has a wider search range than  and cannot
be to blame for not finding the file.

It looks like this gesture in Makefile.am shall add the directory with
this file to the list of include directories:

  libpostgres_la_CXXFLAGS = -D__WXGTK__ \
-I../../dbinterface \
`pg_config \
--includedir`

What does this command put out:

  pg_config --includedir

I understand pg_config belongs to package libpq-dev. Its purpose is told by:
  https://www.postgresql.org/docs/current/app-pgconfig.html

Yes. The problem is with the high reading speed of the drive and with
a physical flaw of Verbatim BD-RE (CMCMAG/CN2/0).
The flaw is that there are letters engraved in the transparent area around
the inner hole, which reach to the thickened ring around the hole.
This ring is obviously essential for physical stability and the letters
weaken it enough so that 10 to 20 full read runs on my Pioneer BDR-209
are enough to produce a radial crack at the hole. This crack grows towards
the rim in a few more full speed reads. As soon as the dye is reached, the
medium is unreadable.

Writing is no problem, because it happens at most at 2.0x speed.
Older Verbatim BD-RE (VERBAT/IM0/0) are no problem. But one cannot buy
them any more.
Reading the new Verbatim BD-RE media is no problem on Optiarc BD RW BD-5300S,
LG BD-RE BH16NS40, and ASUS BW-16D1HT. And of course not with the old LG
drives like BD-RE GGW-H20L which read (and write) BD-RE at 2.3x speed.


> Since I only use BD-R, it

I tested about 50 reads with RITEK/BR3/0 and Verbatim CMCMAG/BA5/0
BD-R media. No problems. (And no engraved letters to see around the
inner hole.)
The media which you inspected by dvd+rw-medianinfo are CMCMAG/BA5
(dunno what dvd+rw-medianinfo did to the "/0" part of the name).


I am still curious whether the decryption problems are caused by
not closing the /dev/mapper device.


Have a nice day :)

I can vouch for that. I got mine (a Lenovo X230) from a store specialised
on that. I topped it up to 16G RAM (that's why it cost 400EUR instead of
the "standard" 200 for 8G). It has given me five years of service and is
still going strong.

Well, I'm a thorough guy ;-) If I do losetup, luskOpen, mount before copying

Exactly.

It tries for all remaining folders, all of them immediately fail because of
disk full and then it waits for input at step 4, i.e. no automatic cleaning up
but if I continue (what I do) it will do the cleanup before burning.

Do I understand correctly, you say that this Pioneer drive doesn't work well
with Verbatim BD-RE, i.e. their rewriteable BDs. Since I only use BD-R, it
doesn't matter for me and my use case, but thank you nevertheless.

For backup reasons, I use each BD disc once, no overwriting, no multi-session,
just write and forget (OK, I should have tested them for readability
afterwards, not just randomly but all of them - lesson learned)  ;-)

Bernd

See the local computer recyclers.
Preferably the ones who handle the government throw-outs.
Government departments, in order to boost their budget allocation, replace as
much of their stock as possible, each year, so some good deals are in the
works.
A good recycler checks everything out, will upgrade the size of drive and
amount of RAM, on request, and deliver on an economical deal with some form
of guarantee.

Off to one side, I have an ACER Travelmate I got in 2017 (2016 model) that
has been as solid as a rock since I bought it. Never missed a beat, costing
me $300 Australian.

It's how I get all my stuff.

Cheers!

Perhaps you don't see it at the moment, but believe me,
it does :)

Now to debug that, you should try to locate the line in the log
where the C compiler is called to actually compile the program.

There you should find what options it is actually called with (esp.
the -I is interesting). If /usr/include/postgresql is in there, I'd
double check that /usr/include/postgresql/libpq-fe.h is there and
readable.

OTOH, if that's missing, I'd make sure your configury is working
properly. Among other things, I'd double-check what pg_config:

  pg_config --includedir

is saying. Perhaps it's lying? Perhaps you're picking the wrong
one?

That kind of stuff.

I accidentally stumbled upon that I can "apt-get upgrade "
and see what is likely the trigger for held packages. For me, it
always hesitates and waits for approval. Most often, packages I've
seen are being held back because of an upgrade to the next versioning
plateau or because completely brand new packages are being installed
along with.

Being able to "-s" simulate with apt-get is something I always forget
exists. I just test drove it, and it worked for upgrade in general:

apt-get upgrade -s

There wasn't anything held back this time so I can only assume that
simulate would additionally work for:

apt-get upgrade  -s

That can be run just like that, as regular User instead of root.

Simulation doesn't give the 100% full picture. It might not generate
enough focus on the held package to answer why it's being held. May be
why I don't remember to use it. I played with simulation a couple
times, and it's a cute trick. At the end of the day, though, I just go
straight for the real upgrade. For me so far, that route has been
informative and has worked safely #1 because it doesn't continue until
I hit the ENTER key again. :)

No pasa nada, puedes probar a montar la partición antes de reiniciar, 
para ver si se monta bien y con los permisos adecuados.

Eso sí, si vas a compartir la partición entre dos sistemas operativos 
distintos, asegúrate de que la montas con los permisos apropiados para 
que puedas acceder, eliminar, escribir... sin problemas desde Debian y 
Lubuntu, ya que serán usuarios distintos los que accedan/guarden/elimen 
los mismos archivos.
