Re: WiFi Not Working After System Reinstallation

[Marko Randjelovic]

Both systems are fully updated Bullseye on a laptop. I have two access  
points, let's call them A and B. When I connect to A, DHCP does not  
work. When I connect to B, DHCP works, laptop gets an IP address and  
internet works without problems. On the other hand, my mobile phone  
can successfully connect to both. Both APs have enabled DHCP server  
and I made sure the IP ranges do not overlap.

WiFy Not Working After System Reinstallation

[Marko Randjelovic]

Hi all,

my wireless network interface is not working after system  
reinstallation. Before it was working perfectly. It cannot get an IP  
address from DHCP. Also, when I assign to it and IP address manualy,  
it's not working. The wired interface is working perfectly. Itried  
with both ordinary and backported versons of the driver available in  
Debian repos (broadcom-sta-dkms).


I hope someone will have an idea on what's going on.

To help us find the cause of your problem, it would be nice if you
could provide us more information: 
- your sound setup (do you use alsa, pulseaudio, jack...)
- which mic device/driver is in question (mic connected to your sound
card which is X, mic from your webcam which is Y...)
- what program do you use for communication (Zoom, Teams, Meet, Skype,
Telegram...)

I had such a problem and solved it by installing firmware for the

I meant 'input source'. On my machine it can be:

'Rear Mic' 'Front Mic' 'Line' 'CD'

You are member of audio group, so that's fine. By 'recording enabled I
meant on/off switch.

In fact, unless you have only one sound device, the command should
be 'amixer -cN' where N is the number of your sound card and can change
after reboot. So first you have to type 'cat /proc/asound/cards' to
find your card number.

Did you make sure:

1. correct device is set to record from 
2. recording is enabled
3. input volume is large enough

If you are not sure send the output of command 'amixer' so we can check.

Maybe you need to install a firmware. What is the model of your
wireless card? Use lspci or lsusb to find out, depending on how your
card is connected. Also you can use

# dmesg | grep -i firmware

to see messages related to firmware (if there are any).

Of course, Mozilla cannot solve Debian bugs and it looks like the bug
is from Debian. It is possible the bug is from Thunderburd (not
Mozilla as Thunderbird is not part of Mozilla anymore), but still if you
don't know it the correct way is to report the bug to Debian and if they
determine the bug is upstream they will forward it.

There is a program named 'flashrom' in Debian, but I don't know how
reliable is it as BIOS flash is quite a dangerous operation. I decided
to risk several years ago on an AMD system with MSI motherboard and was
successful.

The essential fact is that APT always looks any disk in /media/cdrom.
If you want to add another disk, it's possible, but first you have to
mount it somewhere and make /media/cdrom point to that dir. The same
trick you use when you are asked to insert another disk during
install/upgrade packages.

As of my experience, th only solution is this:

Insert the flash.
# mkdir /media/usb0
# mount /dev/sdb /media/usb0 # (replace sdb with device node of your
flash)
# rm /media/cdrom
# ln -s usb0 /media/cdrom

Hi local10,

Launch juk from terminal to be able to see its debugging messages. Also
you can reboot with the old kernel to see if juk works, maybe your new
kernel introduced some bug.

You can download only parts of libreoffice that you need, e.g.

apt install libreoffice-writer libreoffice-calc

Also, you can use --no-install-recommends option:

apt-get --no-install-recommends install libreoffice-writer libreoffice-calc

You have DENIED entries where apparmor prevents qemu-system-x86 to
access files /sys/devices/system/node/ and /sys/devices/system/cpu/.
Try to edit apparmor profile for qemu-system-x86 and reload it
afterwards. Profiles are located in /etc/apparmor.d. There are guides
on the web how to do it.

Hi Ryan,

Check if your video card needs a firmware. Also check if it needs a

Use reportbug tool to file a bug.

Try this to list all packages that are installed and have acpi in
either package name and description:

apt-cache search acpi | while read package_name rest; do if dpkg -l 
$package_name &>/dev/null; then echo $package_name; fi; done

Also, kernel has support for ACPI.

And it's not necessary to know exact package which is to blame, as
package maintainers can reassign a bug report to another package.

Maybe your flash plugins are different, or totally missing from the

flash?

Because linux-image-4.19.0-4-amd64 and linux-image-4.19.0-5-amd64 are
two different packages, not two versions of a package. Install 
linux-image-amd64 package which depends on newest kernel version and it

setenforce 0 works, there is no need to reboot the whole system. On the

no selinux-policy-default in jessie, although there is in testing.

After rebooting with 'selinux=0' I reinstalled dpkg with success:

dpkg -i /var/cache/apt/archives/dpkg_deb

However, then I wanted to install reportbug and during install received
the same error.

If you are working from remote machine, the problem might be restarting
services which kills your connection.

without skipping frames, there is no way to correct a/v desync and in
my case after a few minutes it becomes (too) noticable.

This is my standard command which always worked perfectly and now it

How many times I have to say till reinstall everything worked fine. I
have two files from April that are perfect. It's long time ago because
I didn't use this feature of my computer. It's possible it was broken
even before reinstall as I didn't use this feature since April 2015,
but nothing big changed since than. Maybe one or two security updates
, but maybe none. I use standard packages. 

In April I used version of mencoder from squeeze-backports and now I
tried both the same version and wheezy version and they both work bad.

And I never standardly used ffmpeg for x264.

Marko

The problem disappears with noaudio option so I doubth this article

With 'noaudio' option, messages about skipped/duplicate frames do not
appear anymore and recorded file plays smoothlty, so appears that the
problem is in mixing audio and video frames. I use default container
(AVI). I tried to switch to Matroska and MPEG but got even more
problems.

I also tried to lower video quality to make sure it's not because of
slowness of hard drive and it isn't (frames are still dropped).

I eliminated all but essential options, but nothing changed. I can further try
only without audio to see if the problem is related to mixing audio and video.

Regarding hardware, I've said before reinstall everything was working, and
nothing changed in hardware. I use libx264 and preset=ultrafast which is quite
easy for my CPU. According to 'top', my CPU is 89% idle and mencoder is taking
only 14% of my CPU.

mencoder - Skipped and duplicate frames when recording from TV

[Marko Randjelovic]

I use Squeeze on this machine. It has TV card:
Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder

When recording from this TV card with mencoder, every 0.15s on average,
a message is output from mencoder:

1 duplicate frame(s)!

or

Skipping frame!

When playing recorded file, picture and sound are very loosely
synchronized.

Everything worked fine until I reinstalled system. After that, I tried
to change relevant packages' versions hoping that will resolve the
issue, but it didn't.

For some reason, Emil did respond only to me. In addition to most
notable software from Debian, GnuMed, FreeMedForms, Clinica, I
recommended him also GNU Health, which is officialy part of GNU.
Features for veterinary he needs are not supported bu these peaces of

Suspicious file found in /dev/shm with Rkhunter

[Marko Randjelovic]

While trying to find out how to eliminate messages:

Warning: Hidden directory found: /etc/.java
Warning: Hidden directory found: /dev/.udev
Warning: Hidden directory found: /dev/.initramfs

which are made by rkhunter every morning as cron job, one more message
appeared (when ran /etc/cron.daily/rkhunter manualy).

Warning: Suspicious file types found in /dev:

You can find the file attached. Besides editing /etc/rkhunter.conf,
man rkhunter, run rkhunter from command line and
run /etc/cron.daily/rkhunter, I was reading https://lists.debian.org

The best solution I see is to edit your /etc/cron.daily/apt and set
COLUMNS and LINES environment variables manualy, but
since /usr/lib/perl5/Term/ReadKey.pm belongs to libterm-readkey-perl
package, I would check if this package is installed and if you need it.

On wheezy, this package is not needed for dnsutils. What distro are you
running?

First, to make things clearer, did you check system requirements for
the driver, such as libc version? 

I didn't find web page for this driver. Can you post it's address?

Boot from Install CD/DVD and choose rescue mode. Than you can review

Yes, the card is Radeon R7 240, but I'm not sure about Sapphire.
According to Wikipedia this chipset is lauched Oct 8 2013, so not
strange drivers are still not supporting it (well).

With FGLRX driver computer resets when I press power button to wake it
up, so I am back at vesa.

I'll try PM_DEBUG=true. There is an options in BIOS regarding VGA
integrated on board (which is currently disabled) so I'll try it as
well.

It's an ordinary PC. There is nothing special in Xorg.log, except that
the card is not detected.

It could be, I answered to your previous topic, if you cannot remove
gnome-disk-utility then try to disable it or configure from it's own
interface (from GNOME), but I never used it.

It could be gnome-disk-utility. Do dpkg --configure -a to see if the
package was installed correctly and then type

apt-get remove gnome-disk-utility 

and look at REMOVED section and if other packages would be removed
answer 'n' to cancel (or 'y' if you are sure you won't make damage).

Thanks for your informative answer, it did solve my problem, after
enabling implicit_ssl option in vsftpd (and btw after disabling
ssl:verify-certificate in lftp), I could transfer a test file.

vsftpd with ssl

[Marko Randjelovic]

I installed vsftpd on Wheezy and am trying to make it work with ssl (ftps
protocol).

This is my config file:

listen=YES
anonymous_enable=NO
local_enable=YES
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
nopriv_user=ftpsecure
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
rsa_cert_file=/etc/ssl/private/vs.pem
ssl_enable=YES
debug_ssl=YES
log_ftp_protocol=YES

/etc/ftpusers does not contain user vsftp.

I connect with:

lftp ftps://vsftp@127.0.0.1:21
Password: 
lftp vsftp@127.0.0.1:~> ls
ls: Fatal error: gnutls_handshake: An unexpected TLS packet was received.

In /var/log/vsftpd.log appears:

If I were you I would download kernel source to experiment with
relevant kernel options, but first try:
1. use hdparm to see if your hard drives support DMA and if it is
activated;
2. change IO scheduler to 'deadline' by adding to kernel boot line
"elevator=deadline".

I don't know what Debian release do you use, but since Squeeze, /bin/sh

From Linux configuration:

config SCSI_IPS
tristate "IBM ServeRAID support"
depends on PCI && SCSI
---help---
  This is support for the IBM ServeRAID hardware RAID controllers.
  See 
  and 

  for more information.  If this driver does not work correctly
  without modification please contact the author by email at
  .

  To compile this driver as a module, choose M here: the
  module will be called ips. 


So, your module is called ips. Verify if proper devices are created
in /dev and mounted on your filesystem.

Read some basic introduction about basic networking terms. Then you
could read some basic introduction to Linux networking.

For your current problem, you didn't provide us enough information. We
don't even know if your network cable is pluged in or you expect to be 
cnnected by wireless.

First, it displays an empty line in place of base dir. This can be
solved by modified sed expression:

"?" is in place of character codes which correcspond to

I use LILO, but make sure you install GRUB on your new (300GB) drive,
use fdisk -l /dev/sd[a-z] to find what is what.

Pin php packages to a=oldstable, 500 < Pin-Priority < 990. But to
receive security support for squeeze past this month, you have to
include squeeze-lts repo.

No upgrades (changes) will be performed, but you can pin package to
e.g. "version 1.0*". But if your package in repo gets upgraded to 1.1
then all security upgrades will be based on 1.1 and again you loose
security upgrades. It can make sense only if both versions are
parallely supported but it's usualy not so in same repo, but if you
enable e.g. deb-multimedia, and deb-multimedia has newer version, but
you want version from standard repo, then you can pin to version from
standard repo with wilecard to ensure security upgrades from standard
repo and block major upgrades (other repo).

Kind regards

No one knows it :)

On Wheezy, you can use:

invoke-rc.d  
service  
/etc/init.d/ 

But Jessy will use systemd - systemctl.

Apparently, firmware-ralink is non-free and is required, so looks like
you can't get your card working from installation. You must download
the package from another machine or temporarily use another network
card.

Then install selinux-policy-doc because it should automatically install
modules to allow actions so your installed software works. You can
allow individual rules with audit2allow. If you don't need SELInux,
look at your boot loader configuration and remove "security=selinux"
kernel option.

Re: Updating not working as expected

[Marko Randjelovic]

Use "apt-cache policy" to see what are your repositories' priorities,
and than adjust them in /etc/apt/preferences. That synaptic option
probably changes Default-Release in apt.conf[.d/], but, I don't
recommend it because I think it's simpler to specify everyting in
/etc/apt/preferences.

You can always install syslog-ng, which will replace rsyslog, and which
I believe is Gentoo default.

It looks to me like you use Tor Browser Bundle, while at the same time
debian tor package is installed (and running)?

Use APT pinning. From man page of apt_preferences:

   0 < P <=100
   causes a version to be installed only if there is no installed
   version of the package

So, try something like this:

Package: *
Pin: release a=unstable
Pin-Priority: 50

It's also from the same man page :).

Take a look at mount man page for mount options you can use. You have
general options and filesystem specific options (most probably vfat).

I'm not sure what is your problem, but I guess you don't want to start
X automatically. Do you use a display manager (GDM, KDM...)? Take a
look at your startup sequence and disable relevant service.

We already have: skeleton, /etc/default. I agree it's poor, but 
as I said, and at least for me, the right way is to extend existing software:

(1) add new features to sysvinit
(2) add new software in addition to sysvinit
(3) make init scripts more correct (abstraction)
(4) extend configurability (more options in /etc/default/*)

(3) makes (4) easily possible

And if sysvinit is in accord with UNIX philosophy,
and as they say it is, than I don't see why (1) and (2) would not be
possible, too, and with not to much effort. About what they say as
disadvantages of sysvinit (lack of features), is not really to blame
sysvinit, because it does one thing and do it right[1]. Other features
could be implemented as additional software. On the other hand, what
actually was done was writing new software that make old software
obsolete and that do *many* things, which is not in accord with UNIX
philosophy (and is in accord with authoritarian philosophy).

Every complex software has bugs, including complex init system.

It depends, but if you could do it then I don't see why couldn't you do
anything that is needed later. Besides, configuration files can also
change, just like init scripts. A don't have a feeling that
upstart/systemd configuration is so simple (not so much about syntax,
I was looking at their documentation and there are things such as
'events' and such things have to be properly defined), so it can
also make problems, not just change in init scripts.

We are talking about Debian init system. init scripts do not need to
support Red Hat because they are on systemd and Solaris is not a
Linux distro and it's not realistic to expect scripts could be
portable between Debian and Solaris.

We already moved to a different default shell.

It's because scripts are not correctly done. All scripts that use the
same resource should not reference that resource directly, but instead
by a common function. That way, when resource location change, you need
to change only relevant function. We could just correct such errors,
and make other corrections/improvements/enhancements instead of 
going into vendor lock-in.

If Debian wants to take care about it's init scripts, I would
really be motivated to be involved. That's why I am not sure 
makers of alternative init systems really very much care about users'
real benefit. They could add additional features as additional
software, not replacement software. Or they could work to improve
existing sysvinit. E.g. they could extend start-stop-daemon to return
only when service is ready, or if timeout exceeds to return with error
status. I'm sure it would be much simpler than making all that. I
primarily mean about systemd and upstart, I didn't have enough time to
learn about OpenRC, but at first glance it looks to me significantly
better. If it's development continues in good direction, Debian could
take OpenRC as replacement for sysvinit, so the worst mistake would be
if we now, without enough vision about eventual consequences, take
systemd or upstart as default init system.

Then it's again a lack of feature in server software (lack of initd
support), and not init system.

I didn't write it quite well. I meant about non-standard configuration.

I am sure this is not urgent, Gnome should not be default DE and even
they could easily just make two (or more) DE options in installer.
XFCE4 is on Wheezy DVD-1. 

Decisions like changing such an essential part of OS should not be made
in rush.

With systemd, your system cannot start without DBus to coordinate
processes. This makes early system startup to complicated. You cannot
start your system w/o DBus installed and working. This can also make
problems to small/embedded systems because of increased storage/memory
consumption.

SysVInit simply works. Symbolic links are a simple and natural way to
control system startup. We have update-rc.d. And LSB tags provide
protection for order of services.

We should just improve our startup scripts, instead of adapting
everything to systemd. We would have to learn syntax and way of usage
of systemd, and for additional flexibility we would have to use shell
scripts anyway. 

I do not see enough reasons for Gnome to depend on systemd, other than
forcing us to switch to systemd for interests of big corporations.

I find shell scripts the most efficient way to automate system adin
tasks. It could be because I am a programmer, but at least init scripts
are already provided, and small modifications should not be a problem
even for non-programmers. For new scripts you have 'skeleton' file that
can be easily adjusted for a particular work.

There is nothing more standard/portable in Unix-like systems then POSIX
shell.

I do not see 'start daemons when they are first used' is quite an
important benefit and start in parallel is already supported by
sysvinit (startpar).

I'd say the problem is in the lack of real effort to solve programming

I don't think UNIX philosophy is not so important. First of all, the
principle of all-might is by nature authoritarian. All-in-one
"solutions" are a characteristic of big companies that want to impress
their users, while not giving them enough real benefit. Systemd makes
system startup more complicated and you need to know not only shell
scripts but also systemd syntax. This will make many people unable to
solve their system startup problems and force them pay money to big
companies, which is in essence what big companies want. Debian should
not put interests of big companies above interests of its users.

I do not think UNIX philosophy is not wrong, I think users are
wrong. Users want false impression of power and that only makes them
dependent on the software that makes them such an illusion, similar to
effect of narcotics. Look what RMS says about companies want to
control their users with software.
