Hello:
... printer tool system-config.printer ...
From what I have read on-line, that package is just a GUI to configure the CUPS print server.
But CUPS has its own configuration interface accessible via any web browser. ie: http://localhost:631/admin
What is the use of another configuration interface for CUPS?
Unless it is a(nother) solution looking for a problem.
... how does it work?
See here to check on how it works/how to work with CUPS.
There is quite a bit on the web on how to do it, that link is just the first one I found.
... better tool in the future?
Better than CUPS?
We may (if needed) get a better/improved version of it as it is maintained in a timely fashion.

Hello:
... blindfully write user and password while bluescreened I can log on and monitors function ...
Have a look at what dmesg and Xorg.0.log are printing out, there must be some clues as to what is happening there.
But I don't think it is a monitor problem, there may be an issue with the docking station.
How does the docking station connect to the laptop? eg: USB, special onboard connector, etc.
Is the laptop on batteries when this happens or does it have the charger plugged in?
If not, try it with the charger plugged in.
You may want to check the manuals (both laptop and docking station) and see if there is any related settings you amy need to check.

Hello:
... no real technical reason to exist ...
Quite so.
But it does.
And some money/time (no idea how much it could be) has been invested in producing it.
As per my rant, there are hundreds other more useful abandoned projects in need of maintenance to adopt and help out with in Linux.
Why Nala? Yet another solution looking for a problem?
Maybe because ... ... it registers it in the JSON file under a unique ID.?

Hello:
Synaptic and apt ...
Yes, that was my main point.
I don't think they are old or ancient.
My Ultra 24 WS is ca. 2007 and was considered ancient when I purchased it used/almost new in 2015 for ~US$300.
Still works perfectly well, just added RAM and upgraded the processor.
That said, there's also the well known Timeō Danaōs et dōna ferentēs phrase. (Virgil/Aeneid)
But like I wrote before: maybe it's just me at this age.

Hello:

Thanks for that. 8^)
But it seems (to me) that this application is looking for disadvantages to advantage, so to speak.
Not King's english but you get the idea.
When I see this type of thing I cannot but suspect.
Not sure exactly what ...
Maybe that's just me at this age.
As always, YMMV.

Parallel package downloads.
The ability to select the fastest mirrors.
Package transaction history.
I really cannot see the use for parallel package downloads - I like to keep an eye on the output of my terminal as each download comes in as well as the installation process. apt is very good for doing that.
As for the fastest mirrors, the deb.devuan.org round-robin already takes care of that.
The package transaction history gets stored stored (in plain text) in /var/log/apt/history.log and /var/log/apt/term.log.
That said, this aspect of its workings made me sort of uneasy:
Each time Nala conducts a new transaction, such as installing, removing, or updating a package, it registers it in the JSON file under a unique ID.
I like apt and how it works and if I need more data, there's always aptitude and/or synaptic.
... love new stuff ...
So do I.
But my three* potato (hand held/manual) peelers still work perfectly well after ~25 years' use.
Don't need a new one.

* Why three?
The last time I moved I misplaced the first and the third was a gift.

Hello:
.. gremlins ...
Could well be. 8^D - you never really know.
From what I have read, it would seem that with DFS-FCC (instead of DFS-UNSET, electromagnetic spectrum interference is prevented by avoiding same channel operation with other pre-WiFi equipment such as comm satellites, weather radar, etc.
But the best of it all is that 95% to 100% figure that brings a grin to my face.
Best,
A.
Hello:
... see if it sticks ...
... then what goes on.
Update:
For whatever reason, my WiCD applet now shows me a full green scale and hovering over it I get this:
Connected to "READHEAD 2.4GHz" at [95% to 100%] (IP: 192.168.0.29)
This is almost all the time the link is up.
Used to be ~ 15% to 20% less than that.
Of course, I am quite aware that there are many factors at play with WiFi reception, but maybe country AR: DFS-FCC instead of country 00: DFS-UNSET actually made a difference?
Best,
A.
Hello:

Hello:
... not a worry because your traffic is always passed on ...
Good to know, thanks.
That said, I am quite surprised with the performance of my home made tin-can waveguide antenna.
Properly pointed, I am getting no less than 94% signal and download speeds of 13.5 Mbps on a day when not every TD&H is on the cable.
That's roughly 8 / 9 mts. as the crow flies with a couple of 13cm. walls in between.
Fibre should be much better.

Hello:
Like I do every so often, I was having a quick look at my display printout as my box was booting this morning and noticed the dreaded FATAL.
It does not get recorded in dmesg but it does in /var/log/boot:
$ cat boot | grep -i fatal

Indeed, /lib/modules/5.10.0-0.deb10.16-amd64 has nothing scsi in it:

What about the node that does not have have ??? for its IP address?

Isn't a 97.6% loss rather high?
Is it possible to improve that metric?
I take it that it is between the wireless router and host39.181-89-51.telecom.net.ar, right?

Hello:
... need to check the speed.
Indeed ...
I'll probably get screwed anyway.
That's what an unchecked monopoly/consortium/cartel of 'independent' telcos will get you.
... speed test includes nodes not controlled by the provider.
Yes, I get the gist of it.
... can with great success be presented with an mtr report with the percentage of lost packets in its node.
I already have traceroute installed, I will have to see about installing mtr, learn to use it and write up a script to run in a jiffy if needed.
... provider’s service is at a very high level, partly due to competition.
Competition? 8^D !!!
Sure, it's been heard of by the public and and talked about quite a bit by all the neo-con DHs/AHs that abound around here.
But has anyone actually seen it at work and observed positive results? 8^¡
... speed itself has remained unchanged for more than 10 years, about 100 Mbit/sec.
Interesting, congratulations for that.
Hoping not to be considered indiscrete, a question if I may: how much does that service cost you?
Let's see what the tests say once it has been installed, maybe by mid April.
It is advertised as a 300Mib synchronous all-fibre link direct from whatever is in the area to my apartment, but I have my doubts.
We'll see what happens when it is in place and working.

Hello:
Uncle ...
8^D !!!
... 4-core processor, why do you need a cli?
Because cli is what I should have been proficient at by the time I turned 21, but it was not to be.
Work by day and architecture school by night + lack of funds for anythin IT related did that.
And having a 4-core processor is no excuse for bloated software and who knows what else inside a browser.
... continuously control the speed?
No, not at all.
But I want to know if I am getting what I will be paying (through the nose) for.
And be able to report what is going on.
Multi-national telco corporations are nothing but pirates/thieves.
They will screw you over at every turn/any time they see the posibility of doing so.
... specific speed of working on the Internet with specific sites is more limited by other reasons.
Yes, I am aware of that.

I'll give it a try when I get the fibre.

Hello:
... used it in the past ...
... quite reliable.
Yes, I many times use the web page version.
Seems to work reliably.
But I would want to avoid using a browser, it would be one thing less to take into account.
To be able to view and save all test results via CSV is a plus. (ie: with date/time/server IPs)
Thanks for your input.

Hello:
Seeing how much my (soon to be installed?) fibre connection will eventually cost me, I will be in need to keep tabs on what I will be getting for my retirement moneys.
While I do not expect that complaining to the telco will get me too far, I will need to be able to supply reasonable proof of what is going on should things not go as planned/promised.
To that purpose, I am looking for a way to reliably/consistently measure throughput to compare to what the 'box' says it 'contains'.
While looking around, I have come across this:
https://www.speedtest.net/apps/cli
Anyone used something similar or home brewed?
Thanks in advance.
Best,
A.
