Don't know about GUI program, can't remember of any that was able to do
it. But, console settings are in /etc/default/console-setup. You can
edit those by hand, or run dpkg-reconfigure console-setup. That worked
for me.

Hi Mark, while multi-booting I use the device name in fstab,

It is not always reliable with multiple drives, because device names 
are not stable across reboots. So it is advised to use persistent 
identifiers such as UUID or LABEL instead.


Yes, what you say is true, but not very often and from what I've seen 
is due to mainboard setup or defects in the mainboard causing the bad 
setup due to mainboard SATA connection being mislabeled.


No, it is due to the asynchronous nature of device probing and module 
loading by the kernel and udev in modern Linux systems.


Could be but I've only seen that problem on two computers out of easily 
more than 1000 and one of those was a mislabeled main board under 
warranty and the computer was replaced with another model and the other 
computer has taken out of service.


  But if everything is correct and you are using lets say sda1 as root 
in your fstab your system will use sda1 as the LABEL, I've seen this 
over and over.


Nonsense. sda1 is the block device name and does not have anything to do 
with the LABEL which is a filesystem metadata field.


But all this is advanced setup for people running more than one Linux 
system and having to edit UUID on all systems because you install a 
new system is undesirable.


No it does not have anything to do with multiple Linux systems.


In fstab a label is used as a device name, a uuid is used as a device 
name and /dev/sda1 is a device name, you are just trying to make 
nonsense out of nothing.


And editing multiple fstab config files because I've installed a new 
system is, like I said undesirable and why I use device names in both my 
fstab and grub boot menu.  As you know when a new system is installed 
swap is formatted and it's uuid gets changed every time it's formatted.


I do use labels on external plug and play drives though.

System hardening: adding hidepid to /proc?

[Brent Clark]

Good day Guys

I came across this document:

https://linux-audit.com/linux-system-hardening-adding-hidepid-to-proc/

The idea is to increase security by hiding the display of running
processes, and their arguments, which belong to other users. This helps
avoid problems if users enter passwords on the command-line, and similar.

Its suggesting mount /proc with the option hidepid=2.

I would like to ask:

1) is it safe?

2) did you incur any issues?

3) what are your thoughts


The security audit tool, Lynis, also checks to see if /proc is mounted
hidepid?

[+] File systems

  - Checking mount points

snippet

  - Testing /proc mount (hidepid) [ OK ]

Many thanks

Brent

P.s. I see its not suggested in the ''Securing Debian Manual"

A label or a UUID are not really used as device names, they are used 
*instead* of a device name.


Anyway, this is not the same as what you wrote earlier and is pure 
nonsense :


"your system will use sda1 as the LABEL"

Unless you meant "define 'sda1' as the filesystem/swap label and use 
LABEL='sda1' in /etc/fstab", which is a really bad use of labels leading 
to confusion between labels and device names. Labels are meant to be 
explicit about the contents, not the container.


And editing multiple fstab config files because I've installed a new 
system is, like I said undesirable and why I use device names in both my 
fstab and grub boot menu.  As you know when a new system is installed 
swap is formatted and it's uuid gets changed every time it's formatted.


The Debian installer does this, but I am not sure that all other distro 
installers do the same. Moreover, the Debian installer will format an 
existing swap only if that swap is marked for use (the trick is that all 
existing swaps are automatically marked for use by default, so you have 
to pay attention and unmark them if you do not want them to be 
formatted). IMO this is a real bug in the installer.


So my general policy when installing Debian is to mark any existing swap 
as "not used", and if I want to share an existing swap, I add the line 
manually in /etc/fstab in the new system after the installation.


To address this swap sharing issue you may be interested in the GPT 
partition scheme : among other advantages, it supports partition labels 
and UUIDs (PARTLABEL and PARTUUID) which are independent of the contents 
of the partition, so they do not change when the partition is formatted.

Debian supports them in /etc/fstab since Jessie.

Recent kernel emulates partition UUIDs with legacy MBR/DOS partition 
scheme, but they are less reliable because these PARTUUID contain the 
partition number, and logical partitions may be renumbered after 
creating or removing another logical partition. That is another reason 
not to use logical partition device names in /etc/fstab.

How to use zram ?

I have found no howto for zram under debian,  nor even the word "zram"

I have tried to use zramctl but it refuses with :

zramctl: no free zram device found

I suppose I should init something somewere, but what ?

On the contrary ubuntu has a dedicated zram-config to make the job.

I didn't even know what it is -- but the zram(8) man page and a little
guesswork at least leads in some direction.

I assume you'd want to load the zram kernel module (sudo modprobe zram,
I'd guess) to be in in the fun.

There's some doc about the Linux kernel module itself (just follow the
link in the above man page).

Let us know how it works out and... make a backup first!

I use 'setfont' from the kbd package. It sets it for the current

sessions: edit /etc/default/console-setup. 


The fonts themselves (from which you can derive your specific list of

See the setfont(1) and console-setup(5) manual pages for more

I suppose it is possible that the sensing circuitry or switch (?) in the
headphone jack is faulty or failing so that when you pull the headphone plug
out of the jack socket the audio signal isn't being switched to the speakers,
the plug's absence failing to be detected (or its presence continuing to
be).

I wonder if this hypothesis could be tested in software; it seems you can
do something like

 cat /proc/asound/card1/codec#0 | grep Pin-ctls
(if your sound card is card1 as mine is)

and look for values of "Pin-ctls=in" or "Pin-ctls=out" 

I obtain these values:


  Pin-ctls: 0x40: OUT
  Pin-ctls: 0x20: IN
  Pin-ctls: 0x20: IN
  Pin-ctls: 0x24: IN VREF_80
  Pin-ctls: 0x24: IN VREF_80
  Pin-ctls: 0x20: IN
  Pin-ctls: 0xc0: OUT HP VREF_HIZ
  Pin-ctls: 0x20: IN
  Pin-ctls: 0x20: IN
  Pin-ctls: 0x40: OUT

But they remain the same whether I have my headphones plugged in or not
(I have no speakers).

Anyhow, this is probably a very wild goose chase and a waste of our
precious time.

All my free -th results looked the same.
Could it be it was already there?

Assuming there is an advantage to this, how does one get it going on startup. 
I HAD a sysinit script for it at one time, before the new days of systend.

By default journalctl sends its output to a pager. Most likely that

search-forward-from-point command, adhering to the convention you have

Also, 'more' or 'less' behave like 'cat' when you redirect their
output to something not a terminal (like to a file, or when it's piped
to 'grep', etc).[1]

That last bit probably has something to do with this:

Security updates for Chromium on Debian Jessie

[Daniel Bareiro]

Hi all!

In the last DSA for the chromium-browser package (DSA-3985-1) I noticed
that the updates were released for stable, testing and unstable but not
for oldstable. I think the same thing happened with the previous update.

Maybe I'm missing something and Chromium on Jessie is no longer getting
security updates?


Thanks in advance.

Kind regards,
Daniel

Maybe that will turn up extra information.  I am sceptical about
that though, but see below.

If you want to use SANE on Debian GNU/Linux, all you really need to do
is install the sane-utils package.  Next make sure that your users are
members of the scanner and you should be able to use the `scanimage`
command-line utility.

# That's assuming your scanner is supported, of course.

If you have sane-utils installed already (quite likely if you installed
a graphical desktop environment), could you also provide the output of
running `sane-find-scanner`?

# Normally I see rather little value in running this command, but seeing
# that the Irisscan Express 2 is Plustek manufactured and supported by
# the gt68xx backend, it might give a clue as to the chipset which might
# be of use determining how easy/difficult adding support would be in
# case someone is interested in doing so.
#
# That's a lot of "if"s, so don't hold your breath waiting for support

Hope this helps,

I missed that detail. Dual boot, is that it? Turn the volume way up in
Windows and use the function keys to make sure the speakers are turned
on and functioning before booting into Debian. Turn off hybrid shutdown,
or fast startup, or whatever it's called, as I've heard that can leave
hardware components in a hideous state. I'm not sure what you've tried
so far and I'm not going back to reread the entire thread so good luck.

Assuming there is an advantage to this, how does one get it going on startup.

I have decided to use the following script and it seems to work :

git  clone https://github.com/Jiab77/systemd-zram

You can the remove systemd-zram directory.

Here you can modify /etc/systemd/zram.conf from 33% to 50 for next

Re: How to use zram ?

[Nicholas Geovanis]

I'm trying to wrap my head around what the performance implications (or
advantages) of zram might be in the virtualized environments. Currently for
me that means mostly VMware and a little Xen. There are at least two
aspects, namely its potential use in the hypervisor and use in the VMs.
Does anyone have any guidance on this issue?
Second question: Do we know how the AWS-branded linux AMIs make use of zram
if at all?

Yes, not fondly though, it was NOT a stable utility.

This sounds handy on a memory starved machine. And at 8GB in this 
machine, I'm still using swap, with a 13 hour uptime, 22megs almost as 
soon as I'd rebooted, and still 22. Which I don't fully grok, htop says 
22 megs used for swap, and only about 60% of that 8GB in use. 2258M for 
actual programs. Linux's memory management does not impress me, I have a 
couple machines with only 2GB of ram that can do what this box is doing, 
albeit slower because they are, and I really have to push then hard to 
make them use any swap. Only the pi-3b with only 1 GB is into swap, but 
I've moved its swap out of the sd to rotating media and its much better 
behaved, and feels faster at 5 megs into swap than it ever was using the 
32GB sd card for swap. Well worth the $50 for a 1/4" thick seagate 
terrabyte with a usb-2 cable sticking out of it.

Now wallies has it with a usb-3 cable, I've put one on the rock64, and 
with 2+ days uptime it hasn't touched its 8GB of rotating swap. But its 
also not yet running x, having locale problems that apt and dpkg can't 
fix.

You have configured your system to look for packages on a CD or
DVD.

The configuration is in /etc/apt/  in the sources.list file or
the sources.list.d directory.

You must configure at least one reachable apt repository to get
this to work.

For example:


deb http://ftp.us.debian.org/debian/ stretch main contrib non-free
deb http://ftp.us.debian.org/debian/ stretch-updates main contrib non-free

Freeing up the memory used by idle daemons and other layabouts lets the
system devote more memory to disk caching.

It seems that the maintainer is overworked and cannot provide Jessie
updates for chromium anymore[1].  Somebody else said he might be looking
at it[2], but that was six weeks ago and nothing happened so far.

So while it is not clear when chromium in jessie will be EOL'ed, it
seems advisable to switch to some other browser for now (if you want a
package from Debian, firefox-esr is the only option).

I don't know if this will help, but I read a post somewhere (don't
remember where) of someone who had troubles with the Ideapad 110S
-- sound, touchpad, suspend, etc. -- after replacing Windows 10 with
Stretch.  Installing a newer kernel from Stretch-Backports rectified
those issues along with non-free firmware in the Stretch Repos and/or
proprietary drivers.

I'm interested in any solutions you discover.  I'm looking at the 110S
as a light, compact "travel" notebook.

Thanks for the observation and the references. I was not aware of this.

Here I am using both Firefox and Chromium since sometimes I need to test
some things in both browsers (for example some WebRTC application such
as Jitsi Meet).

Debian v9 it's a stretch

[tony mollica]

Been off the mailing list for a short time but I found something that's 
probably common knowledge by now, but I'll post it anyway.


After a fresh install of Stretch my networking, especially my wifi 
networking, took a turn for the worse, neither NM nor wicd working to 
any degree of connection reliablility.  There were some other problems, 
too.


Aftera another fresh install to a new hdd with all the mods I like in 
place (nvidia) and a new motherboard, processor (4.5Ghz FX) and video 
the network problems persist.  BUT, found one email to a list that 
indicated the problem was likely the persistent network naming being 
incompatible (read 'names too long') with some of the firmware/drivers, 
especially for USB wifi adapters.


Killed the persistent network interface naming and all the network stuff 
now works perfectly.


If the 'old' naming conventions are going away with Debian 10 then maybe 
someone should let the driver folks know this, if not already.

In the past I have used the VC2 shell to swapon immediately the
partitioner has formatted the partitions (but not swap), ie just
before "Install the base system". This has never caused a problem
for me, but the Installation Guide says:

"In particular, you should always use [sic] let the installer activate
your swap partition and not do this yourself from a shell." (§6.3.8.2)

Any idea why?

You can generate somewhat better file names from the preferences or
-much better- you could use a tagging tool like exfalso or easytag to
create metadata and mp3splt will do the naming from these. There's also
an option to generate metadata (i.e. tags) from the filename but I have
never tried that.

Debian 9 bluetooth fails worked on Debian 8 (firmware) bluetooth hci0: firmware: failed to load brcm/BCM20702A1-0b05-17cf.hcd

[Len Berman]

I copied firmware from Deb8 to Deb9; however, the file name needed to
change from BCM20702A1-0b05-17cf.hcd to BCM20702A0-0b05-17cf.hcd, so
when I copied the file, it still didn't work.  It took a while to see
that the file mentioned in dmesg >>really<< wasn't present.

Don't let it happen to you.

The Debian package management system uses a configuration file and a 
configuration directory to determine where to obtain software packages. 
These are:


/etc/apt/sources.list

/etc/apt/sources.list.d


The Debian installer will create a default package management 
configuration file and an empty package management configuration 
directory for you during installation.



This is what the default package management configuration file looked 
like after I did a fresh install of Debian 9.1.0 amd64 XFCE on the 
machine I am using:


2017-09-28 19:20:33 dpchrist@tinkywinky 
~/tinkywinky.tracy.holgerdanske.com/etc/apt

$ cvs update -r 1.1 -p sources.list | nl

 2	# deb cdrom:[Debian GNU/Linux 9.1.0 _Stretch_ - Official amd64 
xfce-CD Binary-1 20170722-11:29]/ stretch main


 3	deb cdrom:[Debian GNU/Linux 9.1.0 _Stretch_ - Official amd64 
xfce-CD Binary-1 20170722-11:29]/ stretch main

 5  deb-src http://approx:/debian/ stretch main

 6  deb http://security.debian.org/debian-security stretch/updates main
 7	deb-src http://security.debian.org/debian-security 
stretch/updates main


 8  # stretch-updates, previously known as 'volatile'
 9  deb http://approx:/debian/ stretch-updates main
10  deb-src http://approx:/debian/ stretch-updates main


Lines 1, 2, and 8 are commented out; they have no effect.


Line 3 is an entry for the installation media.  While it says "cdrom", I 
installed from a USB flash drive.  This is why apt-get(8), or whatever 
package management tool you are using, is asking you to change media 
when you try to install a package -- the media was mounted during 
installation, the package management system is still expecting the media 
to be mounted, but the media was not mounted when you tried to install a 
package.  So, the package management system told you to change media and 
mount the installation media.



Lines 4, 5, 9, and 10 were created by the Debian installer per my 
"Debian archive mirror country" and "Debian archive mirror hostname" 
choices during installation -- I choose "enter information manually" and 
entered "approx:", respectively.  (My local Approx server -- 
https://en.wikipedia.org/wiki/Approx .)



Lines 6 and 7 were created by the Debian installer automatically.


You have at least two choices:

1.  Insert and/or mount the installation media before you install a package.

2.  As root, comment out the "cdrom" line in sources.list, run 'apt-get 
update', and then install a package.



HTH,

David

These are initrd doing.

These are mounted by whatever init you're using (e.g. /etc/fstab,
sysvinit, systemd).
