You may also want to look at RFC 1855 "Netiquette Guidelines". ESR
recommends it. https://www.ietf.org/rfc/rfc1855.txt It's not just a good
idea, it's an RFC. :-)

So were there any errors or warnings in /var/log/Xorg.0.log?

I'd also check for error messages in $HOME/.xsession-errors.

Does your recovery mode have the zfs kernel modules and zfsutil?

Without it, you'll never mount things.

I am unable to find a canonical Debian policy on the subject of posting

Most readers of this list seem to prefer attributed, indented, trimmed,

[Back to the technical discussion.]


I appears that Debian single-user mode does not load the kernel modules 
you need.  I assume this is by design, so that you can boot the system 
when you have a bad module.



Loading modules by hand in single user mode might work, but there is the 
chicken-and-egg question starting with "can you boot into single user 
mode without a /var filesystem?".



I find it is very useful to have a complete Debian installation on a USB 
flash drive with all the software I need to do system administration on 
Debian machines.  Using such, I could easily move /var to ZFS.  But, I 
don't know if the target system would work correctly.



If I wanted /var on ZFS on a Debian system, I would "go the whole way" 
and STFW for a guide on building a Debian system with ZFS-on-root.  Or, 
I would look for a Linux distribution (Ubuntu?) that can do ZFS-on-root 
OOTB.  But, the best answer I have found for ZFS is FreeBSD.

I assume your access point has utilities to determine what channel(s) 
are in use and to survey the radio environment to see how much traffic 
is on each channel.  Run it.  If your access point has the ability to 
dynamically choose a channel with less traffic, enable that feature.  If 
your access point does not, set the channel(s) to those with less 
traffic.  Also, check if the radio(s) have power settings -- it may be 
possible to increase the transmitter power.



How far is your laptop from the access point?  Is there a clear line of 
sight, or are there walls, ceilings, floors, or other objects in 
between; especially objects made of conductive materials and/or 
containing electric circuits?  The ideal situation is to have clear 
line-of-sight between your device and the access point.  In an indoor 
home environment, this is most readily accomplished by mounting an 
access point on the ceiling near the center of every room where Wi-Fi is 
used.  If you use Wi-Fi outdoors, mount an access point to the house 
wall facing the area.  You will want access points that are designed to 
work together.

I've seen the other responses, I just want to throw in my 20 mils: 

I use (to oversimplify) almost plain text files with multiple records in each 
file.  Thus I can have a file named diary (or named something else) and just go 
to that file and start typing.  I can add the record separator (and a title / 
subject, date stamp, and any other meta data I want after (or before) I enter 
the text of the data.

In its current iteration (the 4th by one method of counting) it uses mbox files 
with mbox multiline mail headers as the record separator (and to store the 
meta data).

I can search and modify records in the plain text file, I can also read the 
files in an email client, and my intent is to index them (and and an indexed 
search (using recoll).  (ATM, I'm not actually using recoll, I set it up some 
time ago as a "proof of concept" but when I migrated to the next computer I 
didn't bring it along.

I currently mainly use kate as an editor, with syntax highlighting and folding 
to make it easier to read / access.

Although I'd like to release it some day, it is not yet in the state I'd like 
to have it in if / when released.

If anybody wants more details to try it out for themselves, or to work on it, 
let me know.

The current desire of my work is to migrate to a Scintilla based editor as 
that will give me a wider choice of possible editors, and deal with some bugs 
in the kate implementation (I'd call them kate bugs, but, conceivably, they'd 
say they fixed the bug (after something like 10 years) -- I made a half-hearted 
attempt to adjust my syntax highlighter after they claimed the bug was fixed, 
but it didn't seem to work -- I suspect they did something to undo the fix ;-)

I'd like to get the syntax highligher / folder for Scintilla written in C++,

Most people did not know that there is a feature in the ical that was

Try iperf3.  Install on both machines and start one as a server and one as a

Looks like your BIOS doesn't support Virtualization.


any hints/tips?



I had to enter my computer's BIOS and tell it that Virtualization is allowed.  
(KVM requires Hardware Virtualization.  Qemu by itself doesn't, just in case 
you have a CPU that doesn't support this).



bios claims it's enabled
cpu=amd phenom ii



What does 'kvm-ok' (1) say?


comand not found



The below cmd should do it:

$ apt-get install cpu-checker


Relooking at above, some hints:

Is the command working if you do it as root?

Is your regular user able to interact with Libvirt?

Any firewall filtering 127.0.0.0/8?

Pelican is a static site generator. You write your content in
MarkDown or RST, and then Pelican compiles it into a website by
applying a theme and CSS styles.

Performance is high, because your webserver is only handing out
existing files. Security is high, because your webserver isn't
allowing any writes to anything.

My personal blog is at https://blog.randomstring.org 

You can see many examples at http://pelicanthemes.com

Pelican is packaged for Debian. Although we are a few releases
behind mainline, the difference is all in new features, not 
security.

Thanks A LOT for this really instructive answers, Andrei.

In fact, at last, "Is the bug relevant for you?" was the pertinent
case. (The bugs resulted, after some research, no relevant for my
actual use.)

In the line of the mail-subject:

$ sudo gdebi package_name.deb

$ sudo apt install package_name.deb

Which would be the more appropriate/recommended way/method to install
a .deb file already downloaded?

Thanks again.

Your home directory is not writable by you, so no new files can be created
there.  Run "chmod 755 /home/john" to fix that.

Greg Wooledge on 1st September very kindly gave me a detailed reply to my
cry for help.

I tried to follow his reply but I have lost all my memory following a
stroke.
So it took me some time to do so as I had to relearn the basic file
commands. I got as far as the following:-

" - bash: home/john: Is a directory
  john@john-PC:/$ ls -ld home/john /home/john/.ICEauthority
  dr-xr-xr-x 26 john john 4096 Aug 31 11:46 home/john
  -rw---1 john john 9016 Aug 31 11:21 home/john/.ICEauthority "

This takes me no further forward.

What puzzles me is that the login worked at least 30 times without the
error message and I cannot understand why it stopped.





This takes me no further.

Slow SSH over WLAN? How to check?

[riveravaldez]

Hi,

I'm under the impression that one of my LAN-SSH connections is working
poorly. When I SSH from a wired desktop machine (generic) to a
Wi-Fi-ed notebook (ThinkPadX220) things take irregular and seemingly
excessive amounts of time to happen (you type and the text appears a
moment later, etc.). This is just a
desktop→cable→router→Wi-Fi→notebook (W)LAN scheme.
Issue appears also logging from notebook to desktop.

Also I've been having some apparent poor performance in simple
web-navigation with that notebook (always through Wi-Fi), so, I'm
suspecting: maybe some issue with the firmware-iwlwifi?

$ lspci | grep "Network controller"
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205
[Taylor Peak] (rev 34)

Both machines run Debian testing (updated).

What could I do to check/test the health/performance of the connection
in order to diagnose if there's effectively a problem?

Thanks a lot!

Crack open your favorite terminal and punch in the following commands.

mkdir -p ~/diary/`date +"%Y"` (once)
nano ~/diary/`date +"%Y"`/`date -I`.txt (daily)

The first command will create a "diary" directory in your home directory
and then create a subdirectory for the current year. The second command
will create a text file named for the current date in the current
year's directory and open it in a command-line text editor.

There's no need to install anything, it'll be compatible with any
software that can read plain text and when you want to search for
particular entries you can use grep.

Hey Joe,

Just take a look at Emacs . It can take 
care of everything you need. No kidding, everything or most of the things lol 
;).

With ORG mode , it’s just the perfect tool to keep a 
diary.

Sometimes it’s the only tool I need to get lots of stuff done, like my journal 
(with ORG mode), system administration, any SQL database (I usually use 
postgresql), email management, etc. All of it with just one tool. So good and 
it’s very old, it’s got already a lot of tests and until now it’s as solid as a 
software can be. Give it a try, you will not regret. I love it.

Sincerely,

If you want to publish a blog, I recommend Pelican. If you don't
want to publish anything, I recommend using your text editor of 
choice in a directory structure, with one file per day or week
or month depending on your desire.

Looks like your BIOS doesn't support Virtualization.


any hints/tips?



I had to enter my computer's BIOS and tell it that Virtualization is allowed.  
(KVM requires Hardware Virtualization.  Qemu by itself doesn't, just in case 
you have a CPU that doesn't support this).



bios claims it's enabled
cpu=amd phenom ii



What does 'kvm-ok' (1) say?


The Libvirt mailing list is also friendly.
