Missing Packages.gz file in debian-6.0.7-amd64-DVD-8.iso image
Hi, In debian-6.0.0-amd64-DVD-8.iso image the file Packages.gz exist but in debian-6.0.7-amd64-DVD-8.iso it doesn't! This cause an apt-get update error.

Daemon program that runs scripts when a service become available.
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 This is my network situation, recently I bought a 3G router providing internet connection to my network (an amd64 Desktop PC with Wheezy and a Linksys NSLU2 de-underclocked with armel Squeeze). I would like to run some scripts when 3G router gets connected to the Internet. Using nmap program I notice that a TCP/IP service become available as soon as 3G router gets connected so I thought to use it as a trigger for a daemon program that checks an IP address for available services then automatically it runs scripts. Does it exist such a daemon program out there? Should I write a shell script using some network utility? Thanks in advance for any answer.

Debian on raspberrypi: failed to configure wlan0
Hi everybody,
Following the instructions reported on the Debian unofficial port
home-site [1] I successful installed Debian on raspberrypi 3B 2016 all
works fine for my needs but configuring the built-in wi-fi interface
apparently it works but reporting errors:
~# ip addr show dev wlan0

~# ifup wlan0
RTNETLINK answers: File exists

the ifup command reports that it fails to bring up but the interface is
configured:
~# ip addr show dev wlan0
3: wlan0: mtu 1500 qdisc

inet 192.168.0.9/24 brd 192.168.0.255 scope global wlan0

if I try to de-configure the interface it fails:
~# ifdown wlan0
ifdown: interface wlan0 not configured
How can I de-configure wlan0 and why do I get errors when I bring up
with ifup command?
Some useful information about my configuration:

Linux source 6.1.38 with Debian patches
Hi, I've trouble with the 6.1.55 kernel version, my system had become unstable, I suspect that firefox-esr doesn't work properly with nouveau driver or vice-versa. I've compiled the kernel of the 6.1.38 time ago and I've installed the resulting package so now I have the kernel installed but no longer the package (I deleted it after installation... big mistake). The system seems rock solid with 6.1.38 so I'm looking for the Linux source packages of the kernel 6.1.38 that is a previous kernel release of the current stable distribution (maybe 12.1) does anybody know where can I find it?

Custom kernel 6.1.55 almost unusable cause nouveau
Hi, I compile the kernel for many years, I optimize the kernel compile process using the bdver1 gcc optimization option applying a patch to "arch/x86/Makefile" in the Linux source tree path. Sadly with the 6.1.55 things went wrong it freeze many time, the 6.1.52 is much more stable with nouveau driver, I don't know why. I attach two files, the kernel log and the .config used for compile the 6.1.55 kernel version. The log file is very large, I suggest to filter it with "grep -v" command in order to avoid duplicate entries. I notice that in the kernel configuration program (make menuconfig) for nouveau driver there are four debug options: CONFIG_NOUVEAU_DEBUG, CONFIG_NOUVEAU_DEBUG_DEFAULT, CONFIG_NOUVEAU_DEBUG_MMU and CONFIG_NOUVEAU_DEBUG_PUSH. If you want I can set/enable those options to have more debug information. Does anybody have any clue to make 6.1.55 reliable on my system?

You can either redirect stdout only, or redirect them both into the same file. It has *nothing* equivalent to >file1 2>file2.

At least several years ago some python scripts (unrelated to Debian upgrade however) failed trying to log e.g. non-ascii file paths, etc. I would reset LANGUAGE as well otherwise some programs may use localized messages. Finally, some users might have LC_ALL (despite it is not recommended) or LANGUAGE set in a file like ~/.bashrc. That is why the following approach may be more reliable. Run commands within the "script" session LANG=C.UTF-8; LANGUAGE=; export LANG LANGUAGE with a note concerning csh. To affect messages generated by shell itself, "export" is separated from setting of the variables. Doesn't LC_ALL=C setting override LANG or LANGUAGE settings? On my system I have: ~$ env | grep LANG LANGUAGE= LANG=it_IT.UTF-8 and LC_ALL=C override the LANG setting when used inline of the command.

Does "LC_ALL=C" work on all shells?
Hi, If I want English output of an application I set the environment variable LC_ALL to "C" inline of the command e.g.: ~# LC_ALL=C apt install Reading package lists... Done Building dependency tree... Done Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. If I don't set the variable the apt command return output localized: ~# apt install Lettura elenco dei pacchetti... Fatto Generazione albero delle dipendenze... Fatto Lettura informazioni sullo stato... Fatto 0 aggiornati, 0 installati, 0 da rimuovere e 0 non aggiornati. This is useful when it's needed to submit a bug report or to speak with other people in one international mailing list like this :) (apropos sorry for my English).

The defective kernel module cx23885: it doesn't support suspend and resume. It's a module for a DVB-T PCIe card. If I'm using kaffeine to watch DVB-T channels, I have to close it before suspending. If I leave it opened, kernel module comes up in a broken state. Closing and opening again kaffeine doesn't help, I have to -close kaffeine -rmmod cx23885 -modprobe cx23885 -open kaffeine This happens suspending with pm-suspend. Using systemctl, kernel module is broken after every suspend, even if kaffeine is not running. My system, if I don't restart Picom, freeze after a resume from suspend.

But with setpriv kaffeine was complaining it couldn't find .config/,

Adding the parameter --reset-env seems to fix, kaffeine restarts.
But, after some minutes, it closes. I don't understand why.
My first guess would be that you also need $HOME to be set, or perhaps
the current working directory, or both. --reset-env sets HOME, SHELL,

I have no idea why it crashes later.

mdam: email when re-syncing
Hi everybody, I've mdadm that is running on Debian bookworm that it scans my RAID 5 array. It happened that after a cycle of hard reboot due to system freeze, mdadm starts resync the array. I noticed this looking at the red LED of the HDD activity almost always fired up and the "top" utility that it showed mdadm at 100% of cpu usage. I dunno if all it's OK, here my /proc/mdstat output: ~# cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] [linear] [multipath] [raid0] [raid1] [raid10] md0 : active raid5 sda1[0] sdc1[2] sdd1[3](S) sdb1[1] 1953258496 blocks super 1.2 level 5, 512k chunk, algorithm 2 [3/3] [UUU] unused devices: I was amazed that mdadm doesn't warn me of the re-syncing process had started via an email. If I run: ~# mdadm --monitor --scan --test --oneshot I've the email test-message in my inbox regularly. So is it possible to be warned via email when an array resync process has started? Of which RAID array failures does mdadm warn the user by sending an email? Thanks in advance Cheers -- Franco Martelli

Other criticisms are that the stroke widths (and even the size) later in the table (eg 0x256–1312) are thicker or larger, and many single-width characters are slightly oversize and get truncated at the top & right (eg Ŵ at 0x372, Lj 456).

I backup files and directories stored in the filesystem not raw data. If an error occurs in the RAID, mdadm takes care to warn me via email... I hope! I think he scanned his disks for copies of the superblock but didn't find any and then somehow with a lot of hassle eventually figured out what the partition tables were. So in a catastrophe, partition tables are one more obstacle to cross before you can start actually recovering your data. Me too ran into a catastrophe scenario, I had lost /dev/md0, the reason was using hibernate (suspend to disk) in a logical volume placed inside the RAID. I think it was damaged the RAID metadata. I got rid of this using Debian-installer, I thought that I had loosed everything and I prepared for reinstall, when Debian-installer asked me to create the new RAID I specify all the four partitions, I saved, and magically the logical device and all my logical volumes, embedded in the old RAID, reappeared. To partition was not a trouble in those circumstances. My only mdraid was on raw partitions but that never had any issues. I think zfs effectively does the same, no partitions. Which raw partitions? Maybe did you mean without partitions? I never used zfs it's full featured, I prefer to keep the things simple: RAID -> LVM -> ext4 Cheers, -- Franco Martelli

1620 is the PID of the parent process, the command returns the date when
the parent process had started and the elapsed time as I expected. But
if I do the same command for the its child process (PID 3507):
~$ ps -eo pid,lstart,etime | grep 3507
the command returns nothing.
So, is it possible to have the starting time and the elapsed time of a
child process?

The link you posted it shows rather outdated fixes, it talked about Jackd

daemon misconfiguration
My understanding is that pulseaudio uses alsa for kernel interface and
that speaker-test uses alsa directly. So if one cannot get speaker-test
to sound right, it cannot work with pulseaudio. That why I suggest workarounds
in alsa conf (asoundrc).
I tried several configurations of ~/.asoundrc in these days but nothing
works with "speaker-test". Well some configurations let "aplay" to use
rear-left, rear-right, front-center speakers but "speaker-test" never
sends sound to front-center, rear-left, rear-right and LFE with this

Just now, checking the ALSA configuration in /etc/alsa/conf.d/ I found
the 99-pulse.conf file:

[1] https://alsa.opensrc.org/SurroundSound The link you posted it shows rather outdated fixes, it talked about Jackd daemon and surround, but I have pulseaudio daemon, maybe I've pulseaudio daemon misconfiguration, I tried what suggested here: https://askubuntu.com/a/1304054 but unluckily it doesn't work, this is what's enabled in /etc/pulse/daemon.conf: ~$ grep -v "^#\|^;\|^[[:space:]]*$" /etc/pulse/daemon.conf remixing-produce-lfe = yes remixing-consume-lfe = yes lfe-crossover-freq = 80 and this is what's in the log after a reboot: ~# journalctl -b | grep pulseaudio mag 01 14:57:28 itek systemd[1254]: Listening on pulseaudio.socket - Sound System. mag 01 14:57:28 itek systemd[1254]: Starting pulseaudio.service - Sound Service... mag 01 14:57:32 itek systemd[1254]: Started pulseaudio.service - Sound Service. mag 01 14:57:48 itek pulseaudio[1273]: Hole in stream, cannot fast forward LFE filter mag 01 14:57:48 itek pulseaudio[1273]: Hole in stream, cannot fast forward LFE filter mag 01 14:57:54 itek plasmashell[1390]: org.kde.plasma.pulseaudio: No object for name "alsa_output.pci-_00_14.2.analog-surround-51.monitor" any clue?

(I could live with / aka vg1/root not using dm-integrity, as long as the data/docker/etc volumes are integrity-protected) ? Or how to make grub 100% compatible with a vg1/root using dm-integrity (that would be obviously the final goal!) Thank you for any pointers! I can only recommend you to read carefully the Wiki: https://raid.wiki.kernel.org/index.php/Dm-integrity HTH kind regards -- Franco Martelli
[SOLVED] Re: speaker-test: no correct sound output on LFE and others speakers

I'm using Debian 12 Bookworm, I've no ~/.asoundrc file. My /proc/asound/cards returns: ~$ cat /proc/asound/cards 0 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xfe40 irq 16 1 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xfe08 irq 57 I've 5.1 speakers the LOGITECH Z906 audio system plugged to the PC via 3 jacks (left/right), (Center/Subwoofer), (Rear left/ Rear right). I assume your cabling is right and your SB soundcard has surround out (3 jacks as you describe it, and not mic and line out for instance). The labels on the jacks would confirm that, so would the user manual of your motherboard or sound card. The issue is that speaker-test doesn't play sound to the correct speaker. If I run: ~$ speaker-test -Dplug:surround51 -c6 -s3 -f75 The sound comes from (Center), (Front right), (Rear left) and (Rear right) speakers instead (Front right) only. What's bothering me is that you get sound from multiple speakers while instructing out on only one. The usual issues of these setups with surround analog out are: - channel mapping issues (driver/hardware mismatch) - software downmixing to stereo There are other usual issues with surrount digital out but this is not your setup. You can have a look at [1] for software fixes on this. [1] https://alsa.opensrc.org/SurroundSound I solved by buying a Toslink (S/PDIF) optical cable, and using thus the "Surround 5.1 Digital output" and unplugging the three jacks analog cable. Now speaker-test works nicely: ~$ speaker-test -c6 -l1 -twav speaker-test 1.2.8 Playback device is default Stream parameters are 48000Hz, S16_LE, 6 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 32 to 349525 Period size range from 10 to 116509 Using max buffer size 349524 Periods = 4 was set period_size = 87381 was set buffer_size = 349524 0 - Front Left 4 - Center 1 - Front Right 3 - Rear Right 2 - Rear Left 5 - LFE Time per period = 8,720806 maybe it was a hardware issue with the DAC of my Logitech Z906, it seems that with the three jacks analog cable it downmix to stereo, thanks anyway.

Booting is only possible with Debian rescue, disabling the dm-integrity on the above volume and rebooting. Note that you still can see the rimage/rmeta sub LVs (lvs -a), they are not deleted!

When you booted in rescue mode which ISO image have you used? Thank for your patience, kind regards. -- Franco Martelli
