I should probably remind the list that this situation can be laid on the 
FCC's front desk here in the US, and in most of the countries that agree 
to abide by a common set of rules, that this is by edict, specifically 
to control what are usually software defined radios. The edict reads to 
the effect that it is programmed for a certain class of service, on a 
specific set of frequencies, called channels in normal lingo, and they 
must NOT be capable of having those limits defeated by you or I.


Consequently that portion of the control is a sealed blob you all hate 
because it is not accompanied by src code and there are some hefty fines 
(27,500 USD the last I heard, per instance) they can use against anyone 
disassembling that part of the code.  For a 3 dollar radio at OEM cost?

Cool: second first hand account.  Thanks.
So there is at least some anectodal evidence.

I also found a potentially related reference to a 70's problem
with corrosive wire insulation at 
https://www.ifixit.com/Answers/View/304699/Oxidation+of+copper+wire
but still can't find anything more concrete (and that one doesn't
mention the insulation's dye as the culprit).


 Stefan

I'm convinced after chasing electrons to make them do work since the 
middle of WW-II, that the dye is the most likely suspect. The evidence 
is admittedly thin, but its there by the fact that other colors may 
flex, fatigue from flexing and fail but they are still copper colored 
when cut into. In broadcasting, which I switched to in late '63 after 
getting a 1st phone in '62,  dependability is the target and while its 
not even the biggest reason for replacing a cable, I have probably 
replaced half a mile of it that no longer said it was conductive, 5 or 6 
feet at a time. I've never been reticent about calling a maker who 
screwed up and telling them so. The surprising thing is that of course 
there are folks who've never made a mistake, those soon get crossed off 
my procurement list. However 90% of such phone calls have been met with 
at first surprise, and then thanked for alerting them to what could be a 
costly warranty make good. Those folks filtered to the top of my srcs 
lists.  Some of my hunches have worked very well if only by serendipity.
As a mid market CE, we often would buy yesterdays tech from folks in the 
top 10 markets, so we bought one of the legendary Grass Valley 300-3A/B 
production video switchers, this one from the JCPennys production house 
in NYC. It had some problems, mostly corrosion from NYC's poor air. Chip 
legs turned black, so we bought tarnex by the pint. Several times.


It also had a serial interface, so I wrote an e-disk that worked better 
than grasses $20,000 item, ran it on an old coco2 with floppy drives.


Once I had that working I could ask a circuit to do something and see 
its response. This thing was full of 4 bit wide fifo's, 2 to make an 8 
bit byte.


They were out to lunch and usually late getting back. Called Grass, it 
was special and they were out.  Sorta memory, so I called AMD next, 
yeah, we made them for grass but we've given then a JEDEC number now, 
how many do you want at $1.90 ea, so I ordered a stick of 25.  Fixed it 
right up. I could go on with my war stories, but I'm boring the list 
with off topic rattling. Just suffice to say I've BT & DT many times.


Take care & stay well Stefan.

I'm pretty sure there are various ways to get that color, so if one of
the dyes is problematic, that doesn't necessarily carry over to other
cables using the "same" color, especially if produced decades later.


They have gotten better, the originals in 1975 had a life of 6 months. 
When they started using it for the outer jackets of sata cables, the 
first generation had a life of 2, maybe 3 years. I suspect the diff is 
whatever is between that bright outer jacket and the actual conductors 
coating inside the hot red jacket slowing the migration of the chemical 
failure. Everything I've built in the last 8 or so years, has black or 
tan cables with latches, zero problems.  I've rebuilt 2 years back and 
used new black cables to build a raid 10 for home.



The J.A.Pan Company first used it in their cb radios in the earlier 1970's
for the transmit button on the microphone and I spent the next 5 years
replacing them with Beldon coil cables, then switched jobs, moved 1000 miles
& never offered my services to another CB dealer, I was too busy keeping
a tv station on the air, spending the last 18+ years of my working life as

to about my 8th birthday when I built a crystal radio from parts. So I grew
up with vacuum tubes, quit school in 1948 and went to work fixing the then
brand new things still called tv's.

Are you sure that's actually the case?  I can't imagine that the

And can you point to any kind of evidence/reports that
it affected sata cables?

Yes, and red-insulated wire has been in common use for many decades, on

run together), to automotive wiring, to model train wiring, and I've 
never heard of red (or any other particular color) insulation (or cable

Hi, Sophie.. While you're waiting for others to respond, am typing to
say I just went through this a couple days ago. Our situations are all
so different so this is a recap of what happened for me.

In *my* case, something unknown changed a BUNCH of (but not all) top
level root directory permissions. I found out by accident while trying
to mitigate the first errors I encountered.

At some point, systemd was referenced and was freaking out that it had
lost permissions. That's when I ran "ls -ld /*" and received e.g.:

lrwxrwxrwx   1 root  root  7 Feb 11 14:26 /bin -> usr/bin
drwxr-xr-x   4 1001 1001  4096 May 17 05:47 /boot

drwx--   8 root  1001  4096 May 16 22:19 /root

1001 is the username I was on when the incident occurred. That /root
change is odd because it only changed one of them. Even odder is how
whatever did this made only partial permission changes instead of
altering all child directories under the top level parent "/"
directory.

First sign something was wrong was that I suddenly couldn't log onto
the Internet. Prior to that, everything else worked as expected.

Then I rebooted and landed at an "sh" prompt. A second or third reboot
landed at that dreaded kernel panic screen that only shuts down for me
by punching the hardware ON/OFF button.

I had also done an update/upgrade a few hours before. Newest program
added was Einstein after a different Debian-User thread reminded me it
exists.

In case it helps narrow down a culprit, the last four apt-get actions
I performed between 2023.05.15 and 2023.05.16 are:


 START SNIPPETS FROM /var/log/apt/history.log

(2021.8.0-1, 2021.8.0-2)

 END SNIPPETS FROM /var/log/apt/history.log 

The affected partition is still here, but I didn't have time for
fighting with it. I debootstrap'ed onto another partition, installed a
ton of favorite programs (not Einstein), ran "ls -ld /*" on the new
partition, and all has been well...

So far.

PS I reported this exact kind of thing to Debian Security a number of
years ago. I was "blown off", shown the cyber door. The PRIVATE email
I sent them had explained the situation two different ways to help
expedite their receiving end's grasp of the repeatedly reproducible
direness of what happened.

In last year or so, someone else got credit for reporting a part of
the same thing I reported years ago. I don't remember what was left
out, but whatever it was, someone else has possibly figured it out...
so that it's not just Adobe perping it this time.

And they're perping it in a different way. Adobe had gone straight
down the line and changed everything directly under "/" to a third
party username. No root, no 1001 for that one back then.

Re: Bookworm CUPS Printing Revisited

Thanks to Brian  on the thread "Re: CUPS on
Bullseye and Bookworm" I now have CUPS working on dragon, my bookworm
i386 architecture laptop.

Or I should say, CUPS printing is more or less working but something
else (GTK printing?) isn't. I can find the driverless printer on the
network, create a print queue for it, and print to it.

root@dragon:~# driverless
ipps://HP%20LaserJet%20MFP%20M234sdw%20(C0FB67)._ipps._tcp.local/
root@dragon:~# lpadmin -p M234 -v 
"ipps://HP%20LaserJet%20MFP%20M234sdw%20(C0FB67)._ipps._tcp.local/" -E -m 
everywhere
root@dragon:~# lp -d M234 /usr/share/cups/data/form_english.pdf
request id is M234-3 (1 file(s))
root@dragon:~# lp -d M234 /etc/nsswitch.conf
request id is M234-4 (1 file(s))
root@dragon:~#

So far, so good.

I have two problems:

1) I cannot print from abiword. abiword finds three printer queues:
print to file (which works), M234 (as previously set up), and
HP_Laserjet_MFP_M234dsw_COFB67. The two printer queues do not work. The
former see the printer light up, the "busy" indicator light up briefly,
then nothing. The latter evinces no action on the printer at all.

(I selected abiword rather than LibreOffice because LO is a bit of a
resource hog.)

2) When I print from the command line, I get results printing to M234.
But when I try printing to the other queue (directly to the printer as
I understand it), I see:

charles@dragon:~$ lp -d HP_Laserjet_MFP_M234dsw_C0FB67 ~/test.document.pdf
lp: Error - The printer or class does not exist.
charles@dragon:~$

I copied the printer name from abiword's list of available printers. Is
that the correct way to specify a driverless printer? I also tried
copying and pasting the ipps:// and dnssd:// printers shown by lpinfo
-v. Same error.

According to https://wiki.debian.org/CUPSDriverlessPrinting, "the GTK
print dialog on buster and before (firefox and evince, for example),
has its own way of dealing with a network printer. Unfortunately,
applications that print through this dialog do not make use of CUPS'
temporary queue formation. To have a queue for an IPP printer visible
and usable, users should manually set up a queue with lpadmin, the CUPS
web interface or system-config-printer or rely on cups-browsed to do it
for them. The situation on bullseye and later has improved." Regression?

I started this original thread because I could not get a bullseye client 
to work with this bullseye server but buster clients worked fine..  For 
me, the fix was something that can only be described as serendipity.


Apt had installed a newer kernel about a week back, probably a security 
fix, but since my whole system is behind the best guard dog ever, dd-wrt 
in my router, and I had just rebooted from an overnight freeze up, I 
ignored its blabbing that I needed to reboot until I had another similar 
freeze up Monday morning and had to reboot with the front panel reset 
button. New kernel now running, bullseye server to bullseye client now 
Just Works.


Not supposed to be snarky, but...

Couple folks rather pointedly asked if I ever read changelogs.  But 
before they can be read, they have to be found.  I just spent 2 hours 
with mc, punching f3 on changelog.gz's, trolling thru /usr/share/docs 
w/o finding an entry for kernels.  So where do I find this famous 
changelog I'm supposed to read?  Or are we becoming windoze, and its a 
secret?


Since 1992, a truely complete changelog is quite likely several 
terabytes so a URL link to a tail output would suffice.

You made a comment on Epson products and Debian. I was rather hoping you would
address that rather than bringing up your concern with a possibly buggy printer
from another vendor.

Sorry, I somewhat subscribe to the suggestion Sophie is a chatbot 
learning, and was more concerned with my own problem cups children. But 
a new kernel on this machine, the "server" seems to have fixed the 
armbian bullseye machines.  epson, given their recent attitude about 
linux, and I as a potential customer pretty much quit worrying about 
them since ink or toner for the brothers cuts my per page costs 
noticeably. I've killed a lot of trees since the early 80's. In a way, 
I'm glad they wouldn't sell me a new high voltage board, the color 
reproduction of this inkjet is far far superior to anything I ever got 
out of the color laser.

This is the sort of thing that you install in /opt or /usr/local and

Debian provides OpenSSL (libssl-dev or the older libssl1.0-dev) and GnuTLS

Most projects that want TLS support are developed around OpenSSL, so
you should try that first.  Or, read the project's INSTALL or README

I don't understand why you guys even propose installing drivers from
Epson when printer-driver-escpr package is in Debian and should be
correct for the printer in question? Is there some established reason to
think it won't work? Or you just didn't do your homework?

I get that this saga probably never goes anywhere but I don't understand
this advice, especially from Andrew. It seems to run counter to the Debian
principle of using software that's actually packaged and tested by Debian.



If you reread - I suggest using the Debian package of escputil - I just wanted
Sophie to see that there was an Epson driver which might provide status
for ink tanks etc. - that's why I went through the steps of exactly how
to find the driver.

But yes, this is going nowhere - and there is no lsb package in Debian, I think.

Right. M234 is the name assigned previously. You get the URI(s) of
available printer(s) by running the program driverless. E.g.:

root@dragon:~# driverless
ipps://HP%20LaserJet%20MFP%20M234sdw%20(C0FB67)._ipps._tcp.local/
root@dragon:~#

Then feed that into:

lpadmin -p M234 -v "URI" -E -m everywhere

But edit in a better (for you) name for the printer than M234.

You might get away with something like:

lpadmin -p heskett.printer -v "$(driverless)" -E -m everywhere

but I haven't experimented with that.


And the only printer that shows in the driverless output:
ipp://Brother%20MFC-J6920DW._ipp._tcp.local/
is I believe the only one of 3 references to that physical printer in 
cups, that does not work, it ignores the tray selection passed.  That is 
an expen$ive lack.


Thanks Charles.

I can personally confirm this as true.  Some of the machines at work

the machine's ethernet interface's MAC address.  The vendor's script
runs ifconfig and tries to parse the output to get the MAC address.
This script fails on the recent versions of net-tools.

One might be able to fix that with hexedit or a clone, by changing the

of course.  Better yet, dl the src, find that string and change it back

tool calls the MAC address MAC, and that ip and ifconfig label it with 
different names. That s/b a std but insert the xckb reference to std's,

This method of software protection, from my experience as broadcast 
engineer, can be costly when it fails, and fixing what you paid good 
money for in the faith that it would work forever but fails regularly 
for whatever reason. And our copyright laws do not contain that I know 
of, a provision to allow the possession of a canceled check to be 
substituted for whatever scheme the vendor comes up with to enforce his 
copyright.  Disney got exactly what he asked for.


We at one time in the early 90's bought an editing system that had the 
key buried in the serial port adapter that was used to control the tape 
machines.  With a limited life. The outfit was able to supply a new 
adaptor, once, but had to drive the height of FL to get it from the 
author of the scheme.  And it was his only copy. Lasted about a month 
and once again we had $25,000 worth of disabled software.


In a tv stations production dept, that's a major income hit. At that 
time I knew a uni prof in germany who was pretty good at fixing buggy 
amiga software, so w/o naming names I told the vendor it was not going 
to be tuff excrement to us but to them, but that I would remove their 
broken key and continue to use the software we had paid good money for 6 
months earlier.  Lots of sputtering, I hung up in the middle of it and 
emailed the sw to the prof, had it back with a try this about 6 hours 
later but he missed a third check, so had to go back and search thru it 
again, finding the last check and nulling it out.  We used the hacked 
version for about a year, till we upgraded the editing machines and 
never heard from that vendor again. I heard later thru the grapevine 
that the vendor filed shortly after that.  The hacked copy never left 
the premises so as far as I was concerned the copyright was honored.


The point is that what can be done in software, can also be undone.

As usual, Gene's experiences are due to a misconfiguration that
Gene made and cannot be helped with, despite many people trying over
a period of years.

When you see a post from Gene mentioning liberal use of "rm" and
"chattr +i" on parts of the operating system, do begin to question
what you are reading.

Thanks,

Thanks for the vote of no confidence Andy.

The diff as I see it, is that I refuse to actually run a dns server 
here, bind and I agreed to disagree nearly 25 years ago when bind was at 
4 something and half the planet was cleaning after attacks on bind. The 
other half wasn't aware of anything except the net was dead, no dns.


The box in question was running rh 6.1 so that might give you a time 
frame. 2001 maybe. IDK, IDC.


We bought a block of 16 ipv4 addresses and registered & ran the tv 
stations net access, about 40 mostly windoze boxes preferring /etc/host 
files for local lookups. It works if the router relays, its fast, and 
bulletproof. The way I've configured is to first check the hosts file 
for a match, and failing that, fwd the lookup request to my dd-wrt 
router, and if dnsmasq doesn't know it, forward it to my ISP. And its 
all transparent in about 30 milliseconds.  The reason I used rm on it is 
because back about wheezy I tried to remove it with apt, and its 
dependencies took 247 other packages with it totally killing the system.


I screamed about it at the time, years ago, everybody sneered and made 
fun of me, and ever so slowly the dependencies went away and I can now 
remove it with apt, but it appears I no longer need to. So it has been 
reinstalled.


Take care & stay well Andy.

Cheers, Gene Heskett.

2009!!

  Luk Claes and me, as the current maintainers of net-tools, we've been
  thinking about it's future. Net-tools has been a core part of Debian and any
  other linux based distro for many years, but it's showing its age.

  It doesnt support many of the modern features of the linux kernel, the
  interface is far from optimal and difficult to use in automatisation, and 
also,
  it hasn't got much love in the last years.

  On the other side, the iproute suite, introduced around the 2.2 kernel
  line, has both a much better and consistent interface, is more powerful, and 
is
  almost ten years old, so nobody would say it's untested.

  Hence, our plans are to replace net-tools completely with iproute, maybe
  leading the route for other distributions to follow. Of course, most people 
and
  tools use and remember the venerable old interface, so the first step would be
  to write wrappers, trying to be compatible with net-tools.

  At the same time, we believe that most packages using net-tools should be
  patched to use iproute instead, while others can continue using the wrappers
  for some time. The ifupdown package is obviously the first candidate, but it
  seems that a version using iproute has been available in experimental since
  2007.

All are good ideas, Curt, but the power in iproute is, maybe now s/b was 
lacking, I've literally spent a frigging week trying to get iproute to 
over-ride the broken 169.xx.xx.xx primary route that earlier avahi's 
insisted on putting into a network config, that is why to this day the 
first thing I do after an install, is find avahi and rm it and reboot. 
rm because you could not remove it with apt w/o tearing down the system 
far enough the only recourse was to reinstall.  That is obviously an 
endless loop.


I find that in bullseye, finally, avahi has developed some manners in 
that it is now happy to the the 2nd route. Ditto for NM, it finally 
after a decade of insisting it be done its way even when its way didn't 
work, so that stuff got fixed and immediately a "sudo chattr +i" applied 
so NM could not screw it up. Fortunately, NM had the good graces not to 
flood the logs with "I can't screw it up" complaints.


So while we are making progress in just works networking and its not 
nice to dig up old dirt, but why did it take 10 years to get those 
major, show stopping problems fixed?  That's what I have failed to 
understand. I've been networking stuff since the middle 80's, Went from 
os9 level 1 on an original coco,then level 2 on a coco3 to amigados, 
running exclusively linux since 1998, I've seen kernel bugs get fixed in 
an hour so why did it take a decade to fix that show stopper routing 
problem? I think that is a legitimate question.

So the arguments for its continued usage are extremely tenuous and
basically boil down to, "it's always worked for me!" Which is fine,

of confusion about why it doesn't have some particular feature that
a user, who was not aware that ifconfig is no longer the thing to

That is all fine & dandy Andy, but how about replacing ifconfig with a 
bash script that recommends to the user, ip for hard wired stuff, iw for 
radio stuff. User education solved in one swell foop.  Makes perfect

I don't know what Debian's official stance is, but if you do web searches

<https://www.redhat.com/sysadmin/ifconfig-vs-ip>:
 The ip command is the future of network config commands. ifconfig
 has been officially deprecated for the ip suite, so while many of
 us are still using the old ways, it is time to put those habits to
 rest and move on with the world.


While you are correct, Greg, the lack of documentation to help with that 
transition is staggering. They just thru it on the table and didn't even 
say use this instead.


<https://en.wikipedia.org/wiki/Ifconfig>:
 Many Linux distributions have deprecated the use of ifconfig and route
 in favor of the software suite iproute2, such as ArchLinux[3] or RHEL
 since version 7,[4] which has been available since 1999 for Linux 2.2.

<https://www.linux.com/training-tutorials/replacing-ifconfig-ip/>:
 [...] back around 2009 when the debian-devel mailing list
 announced plans on deprecating the net-tools package due to lack of
 maintenance. It is now 2015 and net-tools is still around.


Those are the most official-sounding references I can find in a few

Unfortunately Tomas, neither util knows anything about radio's.  Someone

(57240 - 63720 @ 2160), (N/A, 40), (N/A)

I have all of mine turned off and everything is wired to prevent the AH 
across the street from using my bandwidth to watch his porn. He had a 
utility on his cell phone capable of hijacking my radios. I hear he is 
back in the hotel for the 2nd time. Life in the neighborhood is much 
improved w/o him.


iw's output seems complete even if there is no radio, which the bpi's 
don't have, but from bpi54:

gene@bpi54:~$ /sbin/iw reg get

note the 00: DFS-UNSET for country. the board doesn't even have a socket

or autmatically by cups-browsed (implicitclass://...). A manual setup on a
bullseye machine would involve the raw or everywhere model. A client.conf is an

But it doesn't seem to work in armbian bullseye, who uses debian repo's 
for everything not involved with booting. Most armbian stuff is u-boot.


I now have different results between bpi54, which works, and bpi51,

What you gave is unknown to ifconfig.

But you said that the problem was "solved" by modifying a setting
corresponding to the Listen directives (in /etc/cups/cupsd.conf).
These directives concern the *server* only.

Oh, then how does one tell the CLIENT to even use the SERVER? That 
statement, added to a created CLIENT.CONF, is not sufficient, Been tried 
many times. It does log a lack of auth, also reported here. Is that the 
real problem? The lack of any tracing info in the log, even at debug2 
level reporting is a huge hindrance to intelligent trouble shooting.



I suspect that your problem was solved for another reason (e.g.
something else occurred on the network in the mean time, or some
config was reloaded at the right time, possibly as a consequence
of your testing). Or perhaps it is not solved at all and could
reappear in the future (that's why it would be interesting to
know the real cause of the problem).


copied new cup-master.zip to the bpi51
unpacked it to cups-master in ~/gene/src
./configure --with-tls=no, no show-stoppers.
make no-show stoppers
make test, failed for 2 functions
the report said at one place it got 34 errors but only expected 33
I didn't install

Back to the apple version installed, what fixed the bpi54 ddoes not fix 
the bpi51, so Vincent was right to be concerned


It is 100% a "cannot assign requested address error" on the bpi51 as

I don't think that you even showed anything. The only test you

immediately refused, then the Listen directive is OK.

For instance:

Escape character is '^]'.

Fine. And you can try the same thing from a different machine on
the network, replacing "localhost" by the IP address of the server,
e.g. from another machine on my network:

$ telnet 192.168.1.3 631
Trying 192.168.1.3...
telnet: Unable to connect to remote host: Connection refused


I'm not able to test that on the bpi's, telnet is not installed.

because my CUPS server just has

Listen localhost:631
Listen /var/run/cups/cups.sock

If the connection is accepted with telnet by using multiple Listen
directives, then the Listen configuration is correct. If you can
see any other issue related to the printers, then the problem is
due to something else.

I'm confused. There is not anything wrong with this machine as a Server.
ALL of this muttering and bitching has been because bookworm clients did 
NOT work. buster clients work great.


How many times do I have to say it is/was a CLIENT problem that only 
exists for BOOKWORM clients.  The elephant in the room that most have 
ignored.


What I have done, on the BOOKWORM CLIENT works, but we still don't have 
a clue why that is so.


That said i've dl'd the src from cups, which is broken by not being in a 
state that will even autogen.  So I dl'd the obviously much later 
src.zip from Mikes new openprinting site. The zip is about 250% the size 
of the apple tar.gz. Its complete and only needs one argument to 
configure, with-tls=no. Then it builds and passes a make test, but I've 
not installed it on this machine.


The debian code appears to be the Apple src.
What I intend to do is move the openprinting version 2.4.5 to one of the 
bpi's, see if it will build there, and install it on the bpi to see if 
that works. But I'm just one, and there is only so much I can do in a day.

Seems obvious enough to me.  CUPS on bpi54 was only listening to

So he had to make it listen to the network instead.

1) Can you put *both* Listen lines in, to keep loopback working?


The cupsd.conf(5) man page says: "Multiple Listen directives can be

2) Failing that, can you use 0.0.0.0 as the Listen address, to listen on
all interfaces?  That's the normal convention.


According to the cupsd.conf(5) man page, you can use "Listen *:631".


The possibility exists that the star goes thru a different path, which 
works. untested here. But folks, that isn't a SWAG, its a plain old WAG.

Close, I wanted to be able to print from the bpi from any app on the bpi 
that had a print this option.  Now I can.


My questions would be:

No, that kills the cups ability to query the network even with the 
Server named in client.conf. It even logs it as a failure, on the bpi5 
but doesn't say why.



2) Failing that, can you use 0.0.0.0 as the Listen address, to listen on
all interfaces?  That's the normal convention.


Untried, so can't say.  And I've not read far enough to see that as an 
example.

My best guess is the Server directive in client.conf was rejected 
because there was already a couple "Listen" directives pointing at 
itself.  Remove the main one and the client.conf was able to take over.
Or the substition of a "Listen ipv4-address-of-server:631" is also a 
possibility.


Whatever, the point now is that it Just Works.

A lot of hacking on C-89 has taken place since the last C book was 
published by K, so I am not the C guru I was in the 1990's.


I'm now 88 yo and some of me has gone to the dogs too.  Take that as an 
admission that my diagnosis might be wrong, but I've been chasing 
electrons to make then do useful work since about 1948 when I quit 
school and went to work fixing them new fangled things called tv's.

Yes, it was necessary, see my previous post. Not determined is the need

That is the first thing cups docs tell you to do, see "printer sharing"


A link would be ever so useful.


send browser to cups.org, click help, in right pane, click "printer

Thanks to you and debian-u...@howorth.org.uk. Note that this page is for Apple
CUPS. The one for Debian CUPS is at

   https://openprinting.github.io/cups/doc/sharing.html

Thank you for that link, the other Apple Cups link is first in a google 
search, and probably close in DDG too since the search was for cups, not 
openprinting as I was not then aware that Mike had moved.  Apple should 
be ashamed of themselves hanging onto the cups links when they are no 
longer writing the authors paychecks.



Havong said that, it should also be noted that the /etc/cups/client.conf is used
when a local spooler is not required and is presented as to be used only as
absolutely necessary. Hardly "the first thing cups docs tell you to do". Why is
it absolutely necessary in your situation?

Additionally, a client.conf overrides the default local  server. All the 
analysis
in this thread has been carried out assuming a functional local  server, so I do
not know where that leaves us now if a client.conf has been in the mix all the 
time..

I am wondering now if I shouldn't remove the other Listen directives 
from cupsd.conf, isolating their influence when there are no locally 
connected printers.


Aha Got it, geany evince okular etc can now print from bpi54! 
Removing the Listen localhost:631 directive from /etc/cups/cupsd.conf 
and inserting a


Listen 192.168.xx.yy:631

made the localhost:631/printers on this machine show up in FF on bpi54, 
all 5 choices from this machine.  All that as root of course, and the 
acid test was me as 1st user, calling up geany to edit that file, which 
complained it was not writable but to print it on the B laser, which 
it just did. I did have to leave active the "Listen /run/cups/cups.sock" 
line, it did not work w/o that.


I changed the LogLevel back to warn before it fills up a 64BG card, and 
it seems its all Just Working.


That warning in the paragraph above s/not be a show stopper when there 
is only one machine as the Server on this local network. IMO, it should 
be speced as applying to any machine that does NOT have any locally 
connected printers.


Your help, and some comments from Greg, have been very helpful.  Thank 
you both for bearing with me, most appreciated.


Take care & stay well.

I don't believe any of these 4 bpi's have libnss-mdns installed, locate

on this net ATM.


Now. I modified /etc/cups/cupsd.conf to change loglevel to debug2, and 
add Listen 192.168.xx.yy:631, then restarted cups, getting this notice 
in /var/log/cups/error_log:


E [10/May/2023:14:32:16 -0500] Unable to open listen socket for address

There's no ipv6 here, none within 100 miles so the first is expected but 
what is the second one telling us?  Permissions, bad path, wrong time of 
the month?  IDK...


This above is on bpi51.

Greg Wooledge's nsswitch.conf line is what would be expected on a machine having

The "search" directive in /etc/resolv.conf is followed by a space-separated
list of domain names.  Yours should say:

search coyote.den

aha! again: was:
nameserver 192.168.71.1

Which is not space separated, thank you, I've got it fixed in 2 places

'lpstat -t' only ever shows *local* printers. That is, printers that have

You are missing the point, lpstat is seeing them, but cups is not.
That it seems to me, s/b where we should be concentrating our discovery 
efforts. FWIW reinstalling cups and cups-browsed has been done, made no 
difference that I could detect. Is there something I could put at the 
top of /etc/cups/cupsd.conf to make any failures or rejects generate 
meaningful msgs in /var/log/cups/error_log?

The facts as expressed are OK. Your interpretation of them is

A lack of understanding about what localhost:631 and 'lpstat -t' show is
the root of problem and colours everything you have written here..

you for the model # of your printer, enter it EXACTLY, the script 
will, if you've net access, goto brothers site, download the exact 
driver your printer needs, install it, integrating with cups perfectly 
but you will probably need to disable cups-browsed as it will make the 
default driver the everywhere driver, crippling 95% of the printers 
abilities.  And from the machine the printer is plugged into, and 
assuming browsed is stopped so you can use the brother driver, it Just 
Works.


Please stop spreading misinformation. I have a Brother MFC-L2740DW 
(which I believe is the exact model you have, or if not very similar) 


I doubt it, does your handle tabloid sized paper (11x17"), including the 
scanner in its lid with an adf? Does it have 2 paper drawers?


and it works perfectly with the "driverless" approach, both with the 
cups ppd generator (everywhere) and the cups-filters pps generator 
(driverless). The first one leads to slow printing for some reason, and 
I had to select "high" quality to get standard quality; the second one 
is as fast as the proprietary driver. Auto discovery with cups-browsed 
also works. There might be some specialized options only available in 
the proprietary driver, but everything needed for general use (tray 
selection, duplex, etc) is available in the driverless driver.


You just showed that it doesn't Just Work, which is exactly why I run 
the brother drivers, which run just fine on a 6 core i5. Every feature 
this printer has, I can adjust from the cups menu's. The driverless 
setup can run this inkjet, w/o duplex because its w/o tray selection, 
printing everything on paper from the top smaller tray normally loaded 
with 50 cents a sheet glossy photo paper.


The proprietary driver is fine and works well, if it suits you, feel 
free to use it. Just be aware that it's only available for i386, not 
amd64, so in a desktop pc you'll need to add the i386 architecture. On a 
Raspberry Pi or other arm computer you won't be able to run the 
proprietary driver.


An arm computer has no need to run their driver, and yes, the rpi4b 
running 1500 lbs worth of 80 yo Sheldon lathe, but running buster sees 7 
shared printers from this machine right now. And they are all usable 
from that keyboard.


If their driver ever had an i386 limitation its news to me.

But please don't say it's the only option because you've been unable to 
use the other ones.


This printer also has a cat5 feed, with an address in my local 
192,168,xx, block, so even if its not plugged into a given machine, but 
the printer and the scanner should still be available at it ipv4 
address. That should be found by cups running anywhere on the property, 
it is not discovered. But I'm mistaken, I now recall unplugging the cat 
5 cable about 2 years ago. USB is faster at data transfer. By about 5x.

I have a Brother HL-L2300D printer.  It is connected to my (Debian

My printer prints sometime.  Other times, it spins up (makes a noise
like it is about to start printing), but nothing comes out. I can't get
any useful diagnostics to tell me where the problem might be.


There is a light at the end of this dark tunnel, IF you are willing to
change the brand name on the printer. But in your case you've already done
that.  So now do a search for brotherusa, go there and download their driver
installer, unpack it, run it sudo if needed. It will ask you for the model #
of your printer, enter it EXACTLY, the script will, if you've net access,
goto brothers site, download the exact driver your printer needs, install
it, integrating with cups perfectly but you will probably need to disable
cups-browsed as it will make the default driver the everywhere driver,
crippling 95% of the printers abilities.  And from the machine the printer
is plugged into, and assuming browsed is stopped so you can use the brother
driver, it Just Works.

However, if its to be shared, usable from other machines on your local home
network AND your other machines are also running bullseye, and some of my
arm stuff is, something is locking out the discovery of shares by cups,
hence my constant harping about it here.  Other Buster machines Just Work
but in my case and to emphasize the point, an rpi4b running buster works but
no banana pi m2 running bullseye can find a printer for cups. But lpstat -t
on that same bpi running bullseye sees them all.


Please give 'lpstat -t' for bpi51 (bullseye) and a buster machine.

as can be seen from its "lpstat -t" it shows all shares, but cups still 
can't see anything. I'm not sure if the pdf generator is installed

[...]

To me, its been a wholesale slauterhouse since cups was sold to Apple.
The only fix I can see will require that we as a world wide group, decide to
monetarily support a cups like fork, getting away from the if it doesn't
suit Apple, it doesn't happen, influence.  TANSTAAFL folks. If you think the

Re: repeat of previous question that has gone unansweredseveraltimes.

[gene heskett]

 for those with the memory for cli.

Is there a deeper problem affecting printing on linux?  I asked work 
colleagues and got two responses:


"oh, shit.  you’re actually printing from linux.  my condolences.', and

"I use Epson and Ubuntu, never had an issue with print over IP - so I 
can attest to drivers working from that perspective atleast"


My perspective is that there is a significant issue, at least for a 
portion of users.


Implying the user is at fault (which Brian isn't necessarily doing 
here,) or acting surprised when someone has trouble printing, is like 
gaslighting.  Maybe it works OK for you, but please understand that is 
not the general case.  Debian can't support every printer for every 
user, but knowing that, CUPS should come with a health warning:  "We 
supply this software as-is in the knowledge that it has known faults, 
and will not work reliably for all users.  We wish there were a way that 
Debian users could reliably print, but there is not.  You may get some 
help on Debian User, but in general printing is not supported."


Thanks,
Alex

An upgrade from 11.x to 11.y should not have too many visible changes.
It's a minor "point release" upgrade, which in an ideal world would
only contain security patches and bug fixes.

Occasionally there's a visible change that makes its way in, but it
shouldn't be major.

You should get in the habit of applying *all* of the point release
updates, every time.  Keep your system up to date on security patches,
and your life will be a lot simpler.

Everything but the rpi4 got a new avahi this morning and that changed my 
cups problems around considerably, but I've not had a chance yet to do a 
full survey. Indications are that some busters are now blocked also.

So why can't another bullseye install use these printers? Buster machines
have 100% transparent access.


Because bpi51 is unable to get attributes from the server to form a PPD file
for HLL2320D_coyote. That is what needs sorting.

The question then becomes what is stopping it, A further clue, maybe, is 
the error log here that reports a lack of auth, but does not say from 
where. that precious little to go hunting for.  Someone more familiar 
with cups might be able to make it spit out more specifics.

A very general question was asked. You answered in terms of your own particular
situation:

  * An unrevealed non-Debian OS on bpi51.


The armbian version of debian  bullseye 11.6 which except for the uboot 
stuff, uses the debian arm64 repo's for everything else.  And which I'm 
pretty sure has been posted.



  * A well-known aversion to Avahi.


Which I have now reinstalled, much to my amazement has not insisted on 
replacing the default route with a 169.number. My aversion to avahi goes 
clear back to long before Jessie because it was not possible to achieve 
a working, local 192.168,xx.xx based network with avahi installed. 
Avahi, like NM has finally learned some manners.



  * An aversion to the everywhere model.


Because it reduces any printer to the lowest common denominator. No 
duplex, no multiple paper trays, huge borders & poor almost unreadable 
fonts.



  * An output from 'lpoptions -p HLL2320D_coyote -l' that indicates a broken

The 1st armbian, bpi51, /etc/cups/ppd does contain the PDF generator PPD
The 4th one, bpi54 /etc/cups/ppd is empty. All were installed with the

in the middle of building a quad of 3d printers around them.


I might be getting on in the middle of my 88th year here, but I can

So it looks to me like cups, to add a printer, needs to be either root, 
ask a sudo pw, or be a member of group lp.


But group lp is bereft of any other members with "lp:x:7:" as its one 
and only member, but cups on these machines has yet to ask me for a pw. 
This looks like it could be part of the original show stopper problem?

Or, am I overthinking this again?

I'd think I could start by comparing cupsd.conf's, but miss And I can't see
the trees for all this forest in the way in both, but missing is a
client.conf. I think... But that is probably whats wrong, me thinking.


A client.conf is unneeded on a well-behaved CUPS system that obtains info
from avahi-daemon.

in the past, its been required to nuke any and all instances found with 
avahi in its name in order to get rid of the totally bogus 
169.xx.xxx.xxx. default route address as is now reported by ip r after a 
reboot.  This has been true even before jessie. However I've now 
re-installed it on two of these armbian bullseye machines w/o losing my 
network. Perhaps it has learned some manners since jessie? Network 
Manager, my other major headache certainly has.


Take care and stay well Brian.

Looks reasonable. A similar command on the server should give a similar output.

The reason 'lp -d HLL2320D_coyote printer.cfg' failed is because CUPS is unable
to query the HLL2320D_coyote printer for its attributes. Printing from anything
else, such as Firefox, will also fail. CUPS on the bullseye machine appears to
be broken.

[...]

A possible way forward is to execute

   sudo lpadmin -p HLL2320D-RAW -v ipp://192.168.71.3:631/printers/HLL2320D -E 
-m raw

which gets me this warning:
gene@bpi51:~$ sudo lpadmin -p HLL2320D-RAW -v 
ipp://192.168.71.3:631/printers/HLL2320D -E -m raw

[sudo] password for gene:
lpadmin: Raw queues are deprecated and will stop working in a future 
version of CUPS.

lpadmin: Use the 'everywhere' model for shared printers.

And I wouldn't use the everywhere option ever as it cripples the printer 
down to the lowest common performing option list, losing among other 
things, the duplex ability. So it MUST use the Brother driver.




and try


then I ran this w/o the sudo:

   lp -d HLL2320D-RAW printer.cfg

And got this:
gene@bpi51:~$ lp -d HLL2320D-RAW printer.cfg
request id is HLL2320D-RAW-1 (1 file(s))

printing the file in portrait mode, full duplex, but the file is wider 
and I would normally put it in landscape mode to reduce the 
auto-word-wrapping confusion. Does -o landscape still work with the raw 
option?


Yes, provided the -olandscape is after the -d argument. That file is a 
3d printer description for klipper, 5 pages in landscape mode.  And is 
the first and 2nd time I've been able to print it. Thank you very much.
Can we continue, making a shell script to do this again with all 
variations available for the -o options of lp?


Take care & stay well Brian.

You have exactly four (not five or six) print queues manually set up on
the CUPS server coyote (192.168.71.3). It is assumed that when sat at
coyote it is possible to print to any of Brother HL-L2320D series, Brother
MFC-J6920DW, HLL2320D and  MFCJ6920DW _tray_2. Im particular - can you
print to HLL2320D from the server?

You have exactly four (not five or six) print queues manually set up on
the CUPS server coyote (192.168.71.3). It is assumed that when sat at
coyote it is possible to print to any of Brother HL-L2320D series, Brother
MFC-J6920DW, HLL2320D and  MFCJ6920DW _tray_2. Im particular - can you
print to HLL2320D from the server?


Yes, and from any buster machine on my local network.

They started on the German mailing list, about a year ago ...

.
The last epson I had that worked with linux was a 4 color C82, well over 
a decade ago. Then it looks as if they started making windows only 
printers because all the normal printer stuff was moved from the driver 
in the printer and put into the windows driver, leaving only the ability 
to put a drop of the chosen color at the chosen xy spot on the paper in 
the printer.  That and the constant battle to keep the nozzle unclogged 
got tiresome and limited the last printer I bought to about 2 months 
life. So that was replaced by a Brother color laser, which worked well 
for around 4 years, then slowly lost its corona wire voltage, an easy 
enough to diagnose problem for me as I am a CET, but brother refused to 
sell me a board despite the fact that I am a CET, fully capable of 
handling that high voltage item. So I brought home their biggest inkjet. 
That was about 8 years ago, and it is still pumping out full color 
images on paper up to tabloid size. A huge device, its also a scanner 
for 11x17 tabloid. I also have a much faster HLL2320dw a B laser that 
does duplex on copy paper at 19 pages a minute. And running on linux, 
using the drivers they supply, both run to their full capabilities.


Obviously I am now a Brother fan and I believe in supporting the makers 
who support us. Glaringly obvious in my previous post. But apparently 
this person doesn't want to admit a mistake was made, and the only way 
to solve it is to run an all windows house at much more cost than buying 
another printer that is supported would be.  Brother's consumables cost 
less per page than epson so you get the difference back over time and 
reams of paper.


This may be a duplicate of what wallmart had for sale at $31.95 3 or 4 
years ago, and which I saw the epson label and drove the cart right on by.

Good afternoon

Thank You
Was it a good idea to buy EPSON?

Regards

In a short answer no. Epson worked very well but that way back, 20 years 
ago.


For high quality output, Brother is hard to beat, and has drivers for 
linux that Just Work. I have 2 Brothers, an HLL2320 laser for fast 
duplex output in B, about 20 pages a minute, and a now several years 
old MFC-J6920DW, an ink-jet that can handle up to tabloid paper in its 
printer and in its scanner, and the scanner can do duplex with letter or 
A4 material as it has an ADF feeder. This printer is both huge and gives 
very high quality photo outputs with every option it has being usable 
with the Debian bullseye I'm running here.


Accessible from USB or from a cat5 connection you can set for your own 
home network. Their installer is a script you can run, telling it what 
printer you have, it then goes to their site, downloads the proper 
driver and installs it in the cups menu's.  The USB connection is faster 
though.


Brother's ink-jet's will use a wee bit more ink than some because if 
powered up full time, will do a quiet nozzle clean at least daily, and 
my MFC-J6920-DW has never had a clogged nozzle in 7 or 8 years now.


Something I can't say for my own history with several Epson's years ago. 
Aftermarket, lower priced ink has been 100% usable but their inks give 
truer color. An ink-jet that Just Works has been a breath of fresh air 
here for quite a while now.


An no, I don't work for or own any Brother stock. I'm just a 21 year 
retired television station chief engineer. I think that makes me an old 
coot. Take care and stay well Sophie

Hi Gene,

If you live close to a large city there will be printing shops that 
serve surveyors that can print large format files. 

exactly
in California the mandated size is 18" x 26" for subdivision maps of 
various flavors.

engineering drawings are variable, 24" x 36" is really common.
I used to have a 36" printer that used 36" wide roll stock, but when it 
died I went to 24"... then after I "retired"
later I started using a Kikos or some such... email them the file, pick 
up the product at the store.

dunno who is better, but lots of people shop it out.

Some Office Max stores can also print large format files.

Best regards,
Fred
There may be something in Clarksburg or Bridgeport that could do that, 
but my truck gets 14.4 mpg and it is a 50+ mile round trip. I have a 
printer that can do tabloid if pushed, but does an excellent job on 
8.5x11 photo paper. And it is done. ;o)>

The package mupdf-tools has mutool, which has a poster

-dsr-
.

Very very close to what I wanted, Dan, better than I expected in fact.

Thank you a bunch.  The help screen says -x and -y is the decimation 
value so I told it .8 for both, okular then printed the out.pdf as 2 
landscape pages missing about 1/16" at the junction then I gave it a -s

Your experience led me to fixing someone else's problem on IRC.
They were trying to install Debian for linuxcnc (but on an amd64 machine)
and had the same problem because they'd left a serial lead plugged in so
got brltty and orca.

I advised them to reinstall to fix things but this time to undo the serial
lead until the install was over. That worked fine for them and they were
very happy. (It's the simple fix that I think I suggested that to you three
times in the course and was ignored.)



Possibly you did, but I didn't glom the usb connection because it came 
with no reason until the last time.



It should have asked me if I wanted that crap but did not.



If you're deafblind and using a Braille reader - it looks for a serial tty.
That's the only way it can work. It can't ask you first necessarily.


That is a huge if. Probably less than 1% of the folks who only fit in 
one box or the other. It could have loaded orca and spoke to me, but 
didn't, it could have asked me on screen and didn't.  What it did was 
make an ass out me in everyone elses mind. Yeah, these days I'm an old 
fart with the poor short term memory that goes with 88 years on the wet 
ram. But I was carving code for an rca 1802 chip before most of the 
readers here were born, doing it by looking up the memonic, and entering 
the corresponding hex code in a quest super elf's hex monitor, code so 
useful in 1979 that it was still in daily use at KRCR-tv when the 
station burnt to the ground in the later 90's, well after Mt St Helens 
blew its top. As a retired television Chief (& usually only, I'm a CET 
too) Engineer, that 16 or so years might as well be a couple of eons, 
the tech, even in never twice same color days, the tech moved a heck of 
a lot faster than that.


My wife of 31 years passed a couple years back and I should throw my 
poles in the boat and go fishing. But I've been diabetic for nearly 40 
years & the water is too cold for my feet, so for S's I'm building a 
3d printer farm instead.



You have all claimed I missed it or told it to install that, but 23 damned
times? I'm sure its here someplace because all 24 times I filled in the
network details manually and was equally amazed when I still had a network
on the after install reboot. That FWIW, was a first.

Everything works except printer sharing and I can't ask cups, my posts to

There are a bunch of cups manpages: there are lots of documents online.
The people recommending you avahi/bonjour/zeroconf are recommending it
because it works - for them and for 99.9% of people.


And its both a lockin for apple, and denies the feature the printer 
maker puts into his product.  And I'm purist enough to object the both.

You betcha. Which gets my posts the TL;DR treatment just because I do

?! First, who's Michael, second, even if it's your friend, you won't

What if it's really a bug, and other people have the same one ?

If you don't know who Mike Sweet is, why are you hassling me?  There's 
25 years of history to computing before Linus released his his linux, 
Michael and I were both there in the trs-80 color computer days and 
while Mike was take college classes and releasing code for the color 
computers in the mid 80's, it was sort of a contest among the coco users 
running os-9 on our coco's, to see who who find and fix the bugs in code 
he released. os-9 was unix that ran on a 8 bit machine with a 65k max 
memory.


Keeping networking working on linux has been an art, not a science.
looking at one of my buster machines. /etc/network/interfaces has this:

# The primary network interface
allow-hotplug eno1
iface eno1 inet static
address 192.168.71.10/24
gateway 192.168.71.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.71.1
dns-search coyote.den

And it Just Works. But that was way the hell and gone too easy, so it 
just had to be changed, so that stuff no longer works for bullseye. 
There is nothing in /etc/network/interfaces.d
So let me snoop, here cuz that entry does not exist on this bullseye 
machine. Looking to see what did make it work, brb.
I can't recall which debian, but at one time I had to put it in the last 
stanza of /etc/dhcp/dhclient.conf but I see that's not been touched, 
here or on a buster machine..

/etc/nsswitch.conf looks default.

Well, I don't know what's the worst ...
And honestly, when you're genuinely confused, you believe and follow the

The weird and frustrating part is that nothing we do or offer seems to
break through the confusion.



So, I got curious about his claim : "that change to resolv.conf adding 
the search line [search hosts, nameserver] has been required since red 
hat 5.0 in 1998".

(The bracket addition is mine)

I'm not using RHEl-based systems a lot so I may be wrong, and there's 
not a lot of material left from the 1998 web, but the resolv.conf file 
*looks* identical in RHEL-based systems, at least nowadays.
I quickly browsed a few RH help pages about resolv.conf, but couldn't 
find his claim.


I then searched for "search hosts, nameserver" on search engines (-with- 
the quotes, to only get full-match results).
Either I get no results or ... wait for it ... it *ONLY* gives me 
results where Gene posted !


So Gene, can you tell us where you read this ?


In a man page from a good 20 years ago. I still have a copy of that 
original redhat 5.0 on a shelf above me, but not a floppy drive to read 
those disks with.


If you didn't read it somewhere, are you using it because :
- it always has been in your config files, which you created at a time 
you didn't really know what you were doing,

- or you followed advice from someone who claimed he knew,
- or it was in a wrongly pre-configured system and you blindly copied 
the stanza ?


That I can't recall for sure, my wet ram is 88 years old, but I had to 
use it yet for a quint of buster installs when updating my machines to 
buster a month or so after it was released. 4 of them are still in daily 
use here. And I just discovered after this round re-started, that its no 
longer required for armbian's bullseye. So as an experiment, I 
re-installed avahi & cups-browsed on these bullseye machines which I had 
removed. And on reboot, I still had a local network on all bullseye's. 
Blew me away.


Take care & stay well.

Cheers, Gene Heskett.

understand how my way Just Works.


How To Set Up A Debian Computer With Static IP Addressing And Hosts File:

1) Install Debian.  Select "Standard".  Do not select a Desktop Environment.

2) Find the name of your ethernet interface, either using "ip link" or
by reading /etc/network/interfaces.  For purposes of this document,
let's say it's "en0".

3) Bring your ethernet interface down:  ifdown en0
This will kill the DHCP client daemon.

4) Edit the /etc/network/interfaces file, and change
   iface en0 inet dhcp
to
   iface en0 inet static
and then add the "address" and "gateway" lines underneath that.
While you're in there, make sure you have "auto en0" too.

5) Bring your interface up:  ifup en0

6) Verify that it works, by pinging your gateway, and then pinging an
outside IP address (e.g. ping 8.8.8.8).

7) Edit your /etc/resolv.conf file correctly for your network.
This means adding a "nameserver" line that points to your DNS resolver.
Do not add lines that are not documented in resolv.conf(5).
Specifically, do not add lines that mimic /etc/nsswitch.cong behavior
in this file, because they do not work.

8) Verify that DNS works (e.g. ping www.debian.org).

9) Edit your /etc/hosts file to contain the IP addresses and names of
other hosts on your internal network.

10) Verify that your internet network name resolution works
 (e.g. ping coyote).

There you go.  That's the whole thing.  That's what we've tried to tell
you to do, for the last 5 to 10 years.

I promise you, Gene, "search hosts, nameserver" is NOT a working line in
an /etc/resolv.conf file.  It never has been.  It never will be.

.
Up to the resolv.conf, that is exactly what I do. But that change to 
resolv.conf adding the search line has been required since red hat 5.0

"search" is used to resolve hostnames to FQDN.
So if you put "search example.com", and you try to connect to a machine with
for example "ssh hostname", the DNS client will try to append example.com to

Welcome to the Gene Heskett show, starring Gene Heskett.

We've told Gene that his configuration is wrong *so* many times, over
*so* many years.  There are very many, very long, threads dedicated to
trying to help Gene get his network configuration to a sane state.

That's not always true.  Sometimes you want the IP address from DHCP,

this is desirable.

That's why this is such an important topic, and why it keeps coming up
over and over again.

That's why we have a wiki page which describes several different solutions,
so that each sysadmin who runs into this problem can find a suitable one.

https://wiki.debian.org/resolv.conf

Thank you for that link Greg.

This explains it better than I do, but if history is any indicator, it 
will be made useless by bookworm.  Thanks Greg, it may contain some clue 
as to why printers on this machine, all marked shared, cannot be used by 
other bullseye installs, Other buster installs however can use them just 
fine. My logs claim the client is not sending any authorization. Yet all 
clients claim DefaultAuthorization is Basic.

I have Google DNS hardcoded on my laptop. Few networks block outbound DNS

And sudo chattr +i /etc/resolv.conf

quickly so NM can't change it. It will remove the search line, killing 
your local network, in which case you can ping yahoo.com, but not 
another machine on your local net. Your ISP's dns has no knowledge of 
your local net which is as it should be.


My router runs something like dnsmasq as its running dd-wrt, and 
theoretically a dns request then searchs the host file for a matching 
name, failing that my whole local system then query's the router, which 
if not cached by dnsmasq, sends the query on to my ISP's dns server, and 
I get answers in around 30 milliseconds. And it all just works. With the 
router NAT-ing, all machines here can browse the whole planet, as 
transparently as border facilities allow.


My main problem with each new release is the ever changing methods of 
establishing each machines repeatable, permanent, name and local address 
on a completely static system described in the /etc/hosts file. Reliably 
setting a domainname used to be once and done, but since bullseye its 
only for this reboot, but I've not found a place to make it permanent 
across reboots, yet...


If anyone knows how to do that on bullseye, I'm all ears. Hopefully it 
will continue to work with bookworm but I'm not a betting man. I'm still 
looking for a way to re-establish cups printer sharing, which Just 
Worked with buster, but is now blocked on bullseye from other bullseye 
machines, but still works with buster machines to this bullseye machine. 
WTH???


Thanks for reading, take care and stay well, all.


Thanks & Happy weekend.

Greetings all;

Where do I turn on cups debugging so I'll see every bit of traffic
addressed to cups from my local 192.168/xx.yy network?

The problem is: other buster machines on this local network can see and
use the two brother printers just as if the printer was local to that
buster machine.

But no bullseye, debian or armbian can see anything at
localhost:631/printers except the search screen when there are no printers.

These printers are marked as shared in this bullseye machines /etc/cups
files.

There's a new roadblock someplace, I've asked about before. I'd like to
find it.

Buster machines can, other bullseye machines can't.

Thank you.

Cheers, Gene Heskett.

Hi Gene,

Not sure if CUPS debugging may be helpful, see eg.

https://sysadminera.com/2020/09/10/linux-how-to-enable-and-capture-cups-debugging-logs/

The most intelligent output I can get from the error_log on one of the 
armbian bullseye machines is a garbled attempt to open a pipe (I think)
from that log a snippet is attached. Tail end of a cups restart. Looks 
like something in the name resolution is totally fubar to me.


But, I can send ff to the exact entry in client.conf, and it can see all 
the shared printers here on this machine. But cups on that machine can't.



But first, I seem to recall you removed avahi and cups-browsed from Bullseye 
machines.  Is that correct?  Do the Buster machines have either or both of 
those installed?


avahi and cups-browsed have both been re-installed on that armbian machine.
And its networking continues to work thru a reboot, something I could 
not do at the original install.
Then I check this machines error_log which is flooded with thousands of 
lines of this from my attempts to get a printer list on the armbian machine:

So the armbian machine is trying, and its this machine that is rejecting 
its attempts.  That's progress ;o)>


Whats next?

Thanks Gareth, take care and stay well.

Cheers, Gene Heskett.
