IMO, allthose question as irrelevant - the problem is the IO. You can try it
easily. get USB 2.0 and put a VM on it - try to start it - you will know
what OP means. Obviously also USB3 are not always USB3 :D

If the problem occurs in multiple distributions, I would suspect a

Re: VMs on external storage CPU overloading

What makes you think so?  Does it overheat?  Is the "load average" too high?
Where is the CPU time spent (i.e. e.g. what does `top` say, is it mostly
in "wait"?  "kernel"?  "user"?)?

Have you tried to install a similar (tho probably smaller) VM on your
internal storage just in order to see if the problem comes from the
external storage or from the VM itself?

This depends on the meaning attached to "support." Debian does not fully
support ZFS. However, the requisite Debian openzfs packages have been in
the contrib repositories for several releases and can be installed
normally, although the file system support has to be built from source
due to license interference between GPL and the CDDL under which ZFS is
released. Behavior is much like the proprietary Nvidia drivers, for example.

Once installed, ZFS can be handled by its relevant utilities much the
same as other file systems. It almost certainly could be used for
storage drives.

Installing an entire system on ZFS is a bit hands on owing to its
absence from the installer. Hand on, here, is to say it is roughly
equivalent to installing early Debian releases or, perhaps, Gentoo. I've
done it four or five times, and after the first is is not painful, but
does take an hour or so longer than a conventional install. Good
instructions are found at

https://openzfs.github.io/openzfs-docs/Getting%20Started/Debian/Debian%20Buster%20Root%20on%20ZFS.html

ZFS is my current default for new installations and I am gradually
upgrading existing installations to it. For a ZFS based NAS, you almost
certainly would be rewarded by increasing memory to the 16 GiB max cited
in the original post.

With respect, Joe is right, in my opinion based on some about 20 as a
DBA and later head of the database branch in a DOD agency.

I quite understand what you are proposing, and over the years the branch
spent a good deal of time and taxpayer resources sorting such
applications developed by accountants to help them in their work. Over
time they grew big and complex beyond their original simple design,
scaled and performed poorly, became infected with data (and formula)
errors that the developers could not fix. All too often the developers
had retired or otherwise moved on and their successors, who had little
understanding of the application beyond its use, were completely at a
loss. It was a mess, and around the time I retired, we did an agency
wide search and found around 500 of them, quite a few critical to
accounting operations yet largely undocumented and often seriously at
variance with accepted accounting rules and standards. The projected
cost of cleaning up was mind-boggling.

Many of those concerns, of course, do not apply to a relatively small
dietary application like you are considering (but consider Joe's size
metrics). A number of them do.

1. Lack of documentation. It takes a lot of discipline to document any
application even to the point where the developer, after a few weeks,
can easily identify its organization and fix or extend it. That is more
difficult with a set of spreadsheets than with a proper relational
database where the defining statements go a considerable way to
documenting themselves.

2. Errors. A decently designed relational database will present fewer
opportunities to insert data errors and make them easier to find and fix
when they do creep in.

3. Work involved. It is entirely possible to design a relational system
based only on CSV or other flat files; Unix, and I suppose Linux even
provides commands for most or all of the fundamental processes, and
desktop machines no more than a decade or so old can perform reasonably
well for small and moderate size databases and straightforward queries,
although performance will fall fairly rapidly with size and complexity,
and designing queries is harder and more labor intensive and error prone
than using a tool - SQL - designed for the job.

I have not looked at recutils, and my opinion is not necessarily worth
much as far as they are concerned. That said, I think it is unlikely
that the learning curve would be lower or less steep than with a proper
DBMS. My preference in a Linux environment is Postgres, but MariaDB and
SQLite are quite up to the task. Any of them can be installed with a
single command, and at least one probably already is installed. Their
configuration for basic use is not difficult, and there are ample web
based and probably public library based sources of "howto" information.

You are the best judge of your situation, but the notion that setting up
and using a proper database is "literally orders of magnitude more than"
a utility based alternative almost certainly is rubbish; it is, at
worst, only slightly more, and the benefits are substantially more.

Tom Dial

Some boards have SATA or eSATA port that would match external USB-drive with
SATA/eSATA. My one did not have it on board, but I added a 2 Port card with
SATA and connect a rather old usb2 box with SATA. It beats even USB3.0,
which I am not sure I have on this PC. Of course it depends also on the
disk and controller in between, but I prefer the external SATA connection
I don't know if it's possible to do on your end.

Re: Homebuilt NAS Advice

Instead of using old hardware, another solution could be to invest in a
small Raspberry Pi and a USB disk.

A year back I created such a NAS solution.
Raspberry Pi3 + 1 TB USB disk

Raspberry Pi OS is based on Debian.

Filesharing by NFS.

I use it as backup media for my servers.
Very cheap to buy, and it all use very little power.

There's at least one US database in spreadsheet form, I found it a
couple of years ago. The problem for me was that the numbers aren't the
same for the UK, even with basic foodstuffs, and the proprietary foods
are formulated for local market preferences. I'm mostly using a UK
database with about 3000 entries.

I wasn't keen on the idea of tapping an Internet database directly.
Firstly, the Net is a lot more ephemeral than we like to think, and
things do just disappear, but also these databases are of variable
quality, often containing alphabetic characters where numbers are
expected. I preferred to make my own databases, cleaning up information
where necessary and dropping most of the nutrients. I also often need
to create entries, both from the sides of packets for packaged foods
and ingredients lists for home-cooked dishes.

If you have been paying attention, you'd know why /in this case/ an UTC
clock makes just a lot of sense.

BTW, many moons ago (as of Windows 3.1, go figure), I was part of a
programming shop. Our boxes had dual boot, Linux and Windows.

To avoid all that stupid problems: among them files "magically"
changing their time stamp at each DST transition -- yes, really!
imagine the fun with Makefiles -- we set Windows to a time zone
on the Greenwich meridian and with no DST. I think it was Liberia
or something. We lived with Windows displaying a funny time.

But hey. Industry standard.

You're looking for a device that has UASP support rather than

I agree, but what with Microsoft and Windows being (almost) ubiquitous,
but swathes of companies developing on that platform conforming to
standards of their own, things aren't too rosy in that regard.

As another example, look at all the bending over backwards developers of
various MUAs go through just to accommodate google's (very) broken
interpretation of email.

Sometimes, whether we like it or not, *we* have to conform to a broken
world.   :-(

VMs on external storage CPU overloading

[john doe]

Hi Debians,

I have limited space on my box, so I would like to install VMs onto an
external storage (usbkey 3.0) using Libvirt.

In the below command '/mnt/usbkey01' is the mountpoint for my usbkey:

virt-install --name=try01 --ram=1024
--disk=path=/mnt/usbkey01/machines/try01,size=6


My CPU overloads like crazy.

The overloading is related by the use of this usbkey but I don't
understand why?:
- Is this a Debian issue
- Is this a Libvirt issue
- Is this expected because I'm using virtualisation with KVM enabled


Other then increasing the size of my internal storage, can I do
something about it?


If I change the path to '/var/lib/machines/try01' (internal storage) it
works flowlessly and my CPU does not overload.


Any input is appriciated.

view you find online) were available in directory `sub/recutils`.

If it is just about offline reading and less about the HTML: Seems the
complete documentation is shipped as part of Debian package recutils
(access it via `info recutils`).



As I'm already familiar with it, I'll use WebHTTrack to get a local copy

Since Windows 7 it's possible to tell Windows that RTC is UTC. IMO,
setting RTC to UTC time is the right thing to do, messing around with
Debian settings to accommodate Windows is not.

Your posts are sometimes nearly... whimsical.

By how much is "Debian time" off? In what timezone do you live?

Background (as another poster has already hinted at in this thread):
Windows is totally naive wrt time: it expects the BIOS clock to
reflect the local time (DST included). Therefore, the BIOS clock
has to be massaged twice a year (if your timezone does the DST
thing).

There is a way to tell hwclock to interpret the BIOS clock at boot
time: you set HWCLOCKPARS in /etc/default/hwclock (CAVEAT: UNTESTED!)
like so:

HWCLOCKPARS=-l

("-l" is for "local", the default being "-u" for UTC). In the default
config file, this line is commented out with a '#' at the beginning;
make sure to remove that.

Should HWCLOCKPARS be set to something, just add the "-l" at the end,
separated by some whitespace.

Note that this localtime thing is discouraged, there are some ways
for it to go wrong (notably, local times are ambiguous in the Spring
change).

Microsoft and time. They didn't miss any opportunity to get it wrong.
Each time.

It's more or less a layer model with different entry points into different
layers.

A GUI login performs a login type with more graphical features. Therefore,
when starting a shell is a subprocess of an already performed login, and a
.*login isn't required anymore.

Login on console instead executes the login shell.

Same is for a remote login like SSH (and for the old men: rsh).

And: a .profile (or .rc) is always executed, as it isn't related to
the circumstance, if it's a login process or a subprocess of a login.

Note: I'm starting a tcsh not a bash as my (login) shell. Therefore I'm
writing the file names in a more abstract way to fit for both.

Klaus.

Honestly, it never was.  Even in the old days, users had different login
shell options, so if you wanted a consistent environment for csh and sh
users, for example, you had to write two different sets of changes.  And
then there were xdm logins, and remote shell logins, and so on.

Every type of login follows a completely different set of steps for
configuring your environment.  Reconciling these and achieving a uniform
environment across all possible login types is *extremely* difficult,
if not impossible.

With a console login, your session consists of a login shell, with some
variables pre-populated by the login program, and by PAM.  The login
shell then reads various configuration files (in the case of bash, these
include /etc/profile and ~/.profile or possibly others; for other shells,
other files are read).

With a "regular" Display Manager login (lightdm, xdm, and so on), your
session is *not* a login shell, nor does it ever at any time include
a login shell, so files like /etc/profile and ~/.profile are never read.
At all.

With a GNOME (gdm3) login, you have *two* different session types: Wayland
or X11.  When gdm3 runs an X11 session, it's similar to the "regular" DM
from the previous paragraph.  However, when it runs a Wayland session,
a whole different set of configs is used.  I've never run Wayland in my
life, but people have said that the Debian Wayland session reads login
shell config files.  I don't know whether that's true, or which shell is
reading them, at what time, or anything.  You'll have to figure that out.

But you said lightdm and i3, not GNOME.  So we can skip all of the GNOME
horror for now.  And please believe me, there are *more* layers of GNOME
horror that I'm omitting here.  It's so much worse than you thought.

A lightdm login running a standard Debian X session reads one additional
file that is unique to Debian: ~/.xsessionrc .  You can configure
environment variables like PATH here, and they will be read and respected
by anything that runs a standard Debian X session.

See also .


Now, after all of that, you still need to consider what your Desktop
Environment does to your environment.  You may go through all of these
steps to set your environment *just* how you like it, only to find out
that in the end, your DE takes over, wipes out some variables, and
changes others.

I suspect i3 is much more traditional and hands-off about it, but I've
never used i3, so I can't say for sure.  You may be totally fine with
just the knowledge contained in this post.  But if you find that some
variables work and others simply do not, it might be because i3 is
resetting them.  It's just a thing to keep in mind.

Linux *is* reading the RTC;  The problem is that Windows expects that
time to be in the local time zone, and sets it so, rather than to UTC,
which Debian (and most Linuxes) expects.  You have to tell Debian that is
the case, and all should be well.

While you're waiting for others to chime in, this is what I do k/t
debootstrap'ing on regular occasion. One of the very first steps in
the debootstrap process is to:

# editor /etc/adjtime

Then fill it with these three lines:

0.0 0 0.0
0
UTC

After that, the next (terminal command line) step is:

# dpkg-reconfigure tzdata

Where we pick from those first choices and then next the more
localized spot that echoes our own local times. When the second step
completes, the feedback I receive looks like this:

Current default time zone: 'America/New_York'
Local time is now:  Thu Jul 30 07:27:23 EDT 2020.
Universal Time is now:  Thu Jul 30 11:27:23 UTC 2020.

Just learned something new myself here after all this time. If I page
down on that second screen (which I NEVER do), it offers "US" as an
alternative to "America". When dpkg-reconfigure completes with that
option selected, the slightly altered feedback says this instead:

Current default time zone: 'US/Eastern'

There may be some professional, universal benefit to using one of
those versus the other so there they are. Right offhand, I can see
where more people around the globe might recognize the geographical
location of New York a lot easier than they might be able to
distinguish between the United States' usage of Eastern and Central
time zones, etc. :)

Hope that helps someone out here. Have fun!

Re: BIOS time fine, Linux/Debian's isn't! ...

[Andrew Cater]

hwclock --hctosys will do it - run a batch file?

Or have ntpdate run automatically as the system boots?

If you mean that Debian shows a different time to Windows consistently -
check that one OS isn't resetting the other's clock. You can persuade
Windows _not_ to reset the clock on daylight saving time changes, for
example - or you can make sure that they both run in the same timezone and
change at the same time.The Debian-specific command:

ntpdate-debian

will run to the ntp pool set by Debian so that you don't have to specify an
NTP server

Yes, I configured it for that in the end, but it still wasn't working.
I'm not even sure why it's working now.

I don't have much recent experience with networking between local computers 
(back in the day (15 to 25 years ago, I used SAMBA) (e.g., NAS), but recently 
started digging into it again.

For my current purposes, I'm finding ssh (sshfs) pretty convenient, partly 
because I recently set up ssh for other reasons and then the leap to sshfs is 
quite small.

I've always had a "learning disability" with respect to NFS, and sort of a 
religious objection to SAMBA (and also some problems with it, but I forget 
what those were, they were annoying things, and just to make up something, 
maybe it had to losing connectivity without being notified or something 
similarly aggravating).

sshfs seems to be outperformed (speedwise) by SAMBA and NFS, but it is hard to 
imagine that being a real problem with modern (fast) computers and 100MB or 
better Ethernet.

If you have sshfs set up, you have nothing more to do on the server.

On the client, you install the sshfs client.

Re: Epson WF-C5290 printer - connection issues.

[rhkramer]

Top posting because this is sort of "off the wall" and may not be directly 
relevant to anything previously mentioned as possible solutions.

I use a Canon BJC-3000 printer (on the order of 20 years old).  It worked 
absolutely fine until 2 or 3 (or maybe even 5 years ago).  

(Aside: I keep the printer turned on all the time, but it does sometimes go off 
due to brief power glitches.  It is connected directly to my everyday driver 
via a USB port.)

Now, about half the time (maybe more often), when I try to print something 
nothing happens.  What I've found that I have to do is turn the printer off and 
then back on again.  Then it goes through it's power on cycle and afterwards 
prints (I ususally have to resend the print job.)

Sometimes it seems to depend on what application I print from, but I don't 
print very often so I haven't pinned this down.

I assumed that it has something to do with some deterioration in the printer, 
but maybe it has to do with some revision in the driver or CUPS software.

Hmm, now I have to check if I'm actually using CUPS ... yeah, cupsd is running 
and I'm pretty sure that is the mechanism of printing.

Maybe it is worth recycling the printer power just before your next attempt at 
printing?

The short (but sometimes inaccurate) answer: ~/.xsession --  this is
(very roughly) the X Session equivalent to your ~/.profile and its
ilk.

The longer answer: man Xsession (5). Depending on whether you use a
desktop environment (and on how badly it has brutalised your X setup),
you'll have to find out what is missing where.

Look around /etc/X11/Xsession.options and /etc/X11/Xsession.d/* --
there is the machinery which decides whether and how to load your
personal X session stuff in ~/.xsession.

Sigh. It /used/ to be simple.

Need help with PATH variable (i3/debian buster)

[Benedikt Tuchen]

Hello,

I got some strange behavior with my PATH variable and maybe somebody
here can help me with this.

When I use no display manager like lightdm, I start i3 via startx in
the console. If I do this dmenu and rofi are using my personal $PATH
variable. For example it includes "$HOME/.local/bin". But when I
use a display manager, dmenu and rofi do no longer have my personal
$PATH entries. How can I change this behavior?

I've tried to find a solution for this but didn't found one. Maybe
someone here know exactly what to do.

Uh it's been a while since
https://wiki.debian.org/InstallingDebianOn/Lenovo/ideapadS205/wheezy

But lately I repurposed that for some test and had
Alpine installed, so in general it's still well supported by
Linux. Maybe I managed some time next week to give it a try with
Debian again.

Ok so the grub issues are still there one way or another.
Maybe you can take a look at what got generated in

The netinstall used a approx mirror here in my LAN.  I did an expert

I am not using IPV6; the LAN gateway address is 192.168.1.1.

Inasmuch as I used the approx mirror, re-installation would be easy,

I am finding that Debian and/or Linux have issues on my older hardware.


If you have a machine with a working installation of:

debian-bullseye-DI-alpha2-amd64-netinst.iso


Boot it and see what message follows the message:

IPV6: ADDRCONF(NETDEV_CHANGE): enp2so: link becomes ready


My guess is that whatever follows is the problem on the Lenovo S205. 
Perhaps you can boot the installer into a rescue shell, mount the root 
partition read-write, and fix or work-around the problem.



What happens if you install current Debian Stable?


What if you install older versions of Debian?
