debian-cd baking process
Hi all! I'm not quite sure where to address this to, but I'm certain this is a bug: If you download debian installer media, for instance debian-12.4.0-amd64-DLBD-2.iso, they prominenty include the files "README.txt" and "README.html". Those presumably somehow auto-generated README files say, in the case of former example: "this disc is number 2 of a set of 1 discs" Which is obviously false. Could anyone please help me find where to file this bug to? Any ideas much appreciated. Maybe there's a bug already that I didn't find. -- Kevin Price

But "the bug" (#1057967/#1057969) won't only disable the wifi adapter, but would probably make the running computer largely unusable, even unable to shut down. That's confirmed. In that case you still might have access through LAN IOT possibly fix GRUB's configuration, if you find a way to do that without sudo, and working around whatever problems you'll encounter attempting that. But even then, that new GRUB configuration will never come into effect until you forcibly reboot/power cycle the computer. (which has always been a bad thing to do in the first place) Under these circumstances, "the bug" can become a huge problem.

Exactly. Mere presence of wifi adapters will cause debian to load their respective wifi driver modules, that in turn will invoke cfg80211, maybe or not triggering cfg80211's bug. > (Not just Broadcom either; at least one > person reported an issue with Realtek.)

My worst guess is 12.5, in a few months from now. But 12.4 might likely work perfectly fine for you, out of the box. If not, you can make 12.4 work for you right now. Here are some of my findings, assumptions, and educated guesses for you regarding "the bug". Hoping to help you, no guarantees. Any risks are yours, as always. "The bug" (Bug#1057967 & Bug#1057969) occurs only in kernel version 6.1.66-1 (package -6.1.0-15, released with bookworm 12.4). No other debian kernel version has this bug. It might not affect you, and it can be remedied/worked around. If it does affect you, it won't fry your filesystem, but the computer won't run properly under this kernel, causing a lots of problems, making your computer largely unusable during this runtime. I don't see any great danger in giving it a shot, if you're reasonably careful to understand, and prepare for what might go wrong. (The much more dangerous kernel would be its predecessor, 6.1.64-1, package 6.1.0-14, which was briefly released in bookworm 12.3, and very quickly retracted. It might toast your ext4 filesystem. (Bug#1057843) For that very reason, no official 12.3 media were ever publically released. See the latest messages at https://www.debian.org/News/2023/ ) "The bug" (Bug#1057967, Bug#1057969) is within the kernel module cfg80211, which is used for Wifi in general, regardless of your adapter's specific WiFi driver. If your computer has WiFi, even if you don't intend to use it, debian (including installer) will by default try to load the appropriate driver modules, which will pull in cfg80211. In case of the non-free broadcom-sta driver, binary "wl.ko" is known to trigger the bug in cfg80211 in 6.1.66-1/6.1.0-15, which then causes lots of problems during runtime. Whether any other WiFi drivers trigger this bug as well, IDK. The _free_ broadcom driver (see https://wiki.debian.org/bcm43xx ) doesn't seem to trigger this for me, YMMV. Non-free drivers are not shipped in official bookworm media, but if you actively choose non-free during the installation process or later, broadcom-sta might then be installed, triggering "the bug". Don't confuse this with non-free firmware. This is indeed shipped in official bookworm media, but most likely won't trigger "the bug". In your case, I'd try the bookworm 12.4 installer straight. By chance, everything might turn out well. If promblems occur that look like "the bug", I'd try one or more of the following possible remedies/workarounds, each of which _might_ suffice, but might cause some error messages or other issues. As soon as you've updated to 6.1.67-1 (6.1.0-16, about to come), any remedies/workarounds should be safe to be reverted. Maybe try the least inconvenient ones first. I haven't tested all of them. * Avoid "non-free". "non-free-firmware" should be O. K. * Turn off your physical RF kill switch. * Physically remove your WiFi adapter. * Blacklist "cfg80211". * Blacklist "wl". * Use bookworm 12.2 installer media, but not netinst, without internet access. Do not allow kernel updates, until 6.1.67-1/6.1.0-16 is available. Presumably some of the folks in this list/thread might come up with even more possible remedies/workarounds. Again: no guarantees. Some of the above is not confirmed or tested. All you do is at your own risk. But I hope I could help you understand "the bug" and how to possibly avoid it, giving you more confidence in what you're attempting to do. Please feel free to ask any further questions to this list, and any reports I'd welcome here. -- Kevin Price
Re: From which kernel should I upgrade my installed Debian to linux-image-6.1.0-15-amd64?
l. Always have one extra, really. This weekend that little extra carefulness paid for me. Another time, it will for you. Given all the above, in conjunction with autoremove, this might have made some people's computers stranded with only -14 and -15 to boot from. Out of which one might toast all their data, and the other one might go nuts if their computer has wifi, and by chance they're using a driver that cfg80211 can't cope with. Those users would be then out of luck. What a terrible mess. /o\ I strongly believe in debian's honesty, because debian is based upon its social contract.[2] Have you read and understood it? (It's a very pleasant read.) The debian project is designed to be free and open, and to be incapable of covering up anything that might have gone wrong. Much better than that: Debian will publish just that in most detail. Having screwed up twice in a row, debian will confess, big time. Had I mentioned blog posts? (We might need a word with the moon regarding its blue occurrence. Maybe don't do that twice in a weekend, please?) Debian is empowering users. That includes that debian will never accept liability for making anyone's computer unusable. If that ever happens, then it's the user who's done it. Debian focuses on providing a free operating system to anyone, enabling them to make best use of their computers. And debian goes great lengths to help users prevent screwing up. In order to get things straight (get kernels working), debian's Salvatore Bonaccorso has been wonderful in pinpointing the -15's bug to the cfg80211 module, and developing a remedy, which will hopefully be introduced with future 6.1.0-16 maybe, soon to come. Not again hastily: It's ready when it's ready. That's how debian's been excellent for 30 years. So please feel empowered, use debian as much as you like, and if you feel gratitude or appreciation, please feel free to express any of that. Maybe towards the release or kernel teams, who've been working unpaid nightshifts for 12.3, which suddenly became 12.4, and who still are, for the folks who need to solve that -15 wifi bug. What are they doing it for? For the good, expecting nothing in return. Just enjoy! (Since you'd explicitly asked for advice, I hope there was not too much mansplaining.)

Currently the prime suspect is cfg80211 (WiFi). So there _might_ be a debian 12.4.1 coming up, who knows. I'd _not_ universally recommend 12.4.0, which uses the faulty kernel 6.1.0-15.

What happens, at a first glance: 1. Bootup to the gdm greeter works, but there I get an unusal keyboard layout. And everything takes longer. 2. There seems to be no network connectivity. (no WiFi icon) 3. Launching Firefox apparently does nothing. 4. Launching gnome-teminal works, but many commands just stall, such as "sudo dmesg" or "ip a". 5. Shutting down takes ages, with systemd waiting for a bunch of services to terminate, most of which seem to be network-related. After much more that 10 min I used hard power-off. I'm uncertain whether such an unstable system is even capable of going through the reportbug script. Any ideas, which logfiles might be useful to debug this issue, and whom to address this to, IOT to prevent similar experiences from many more users?

You are very welcome. Thanks a lot for this conversation, which felt very pleasant to me, and kind, productive, and helpful, even though especially my initial reply was quite tight-lipped. Thanks to our well-working cooperation. We've successfully and quite quickly pinpointed the cause of a real-world problem that likely affects many others. ^5 IMHO, this is a good example of how I wish the Debian/FLOSS community to always be. Or any good community, for that matter. If I may: Very well done, Casey. *shoulder tap* What caught my initial attention was the possibility of the kernel broadly changing its behavior within a stable release, which in itself would pose a huge problem, which to prevent is the very purpose of stable. Glad that turned out to be false. Your appreciativeness encouraged me to follow up on this, which rewarded me with quite some fun in helping to solve this little puzzle with you, and with the bonus of a few decoys in our way. ;D Out of curiosity I've subscribed to your bug #1018999. Very well written. Its outcome we'll see. As to if, when, and how it might get fixed, I'm not all that optimistic, so you might want to stick with any workarounds for a while. (maybe a tailored deb package that _Conflicts_: connman and _Recommends_: network-manager, or else maybe a kernel boot command line parameter "ipv6.disable=1", which completely overrides sysctl, or whatever may suit your needs) Although connman is actively being maintained upstream and in Debian right now, it's far from granted this bug will be acknowledged as such at all, either in Debian or upstream. Otherwise it might be dismissed as connman's "expected behavior". Although I'm not in favor of that in this case, I do understand the argument that a program designed for the sole purpose of managing network interfaces, actually manages network interfaces. Maybe not in the way we'd like. Maybe it could manage them to more satisfaction by asking permission before overriding the user's preference to disable_ipv6, which it doesn't. Thus #1018999. In case your bug gets acknowledged, (which is a huge if) I'd expect any resolution to appear in stable no sooner than in Bookworm, whenever that may be released. (...very purpose of stable...) Also, in case bug #1018999 is not going to be fully resolved to your needs, we might consider filing a wishlist "bug report" against lxde to at least change their recommendation into something less troublesome, such as network-manager maybe. Which does not interfere with the user's preferences in the same way. Oh BTW, I ought to file another bug report against connman (if not already pending) for not being able to be installed via ssh in a DHCP environment. (because during postinst it reconfigures the network interfaces, failing to use the proper FQDN in DHCP requests, thus getting a new IP address assigned and cutting off the ssh session) Not quite certain, but I guess this violates some existing Debian policy, or else a new Debian policy to come into place rather soon.

You might want to look up why that is: * DFSG #1 https://www.debian.org/social_contract#guidelines Further reading, two other attempts to define basically the same idea: * freedom 2. https://www.gnu.org/philosophy/free-sw.html * 1. https://opensource.org/osd -- Kevin
Linux Kernel 5.16 from Backports Warnings

Chromium GPU sandbox error
Hi all, When opening chromium 99 I'm seeing the following error in the logs: ERROR:sandbox_linux.cc(364)] InitializeSandbox() called with multiple threads in process gpu-process. I've tried following the advice of setting the environment variable : export MESA_GLSL_CACHE_DISABLE=true And I'm still getting the same error. Anything else I can try? - Kevin
Re: Simple and secure blogging software for nginx
Static site generators are very nice to use. Gives you a simple text editor for writing and then you just let the generator link all the pages and add the pre-defined styling. Never have to run down broken links again. They take a little configuring to get it right initially though so you need a little patience right in the beginning. - Kevin On Fri, Mar 11, 2022, 8:39 AM Christian Britz wrote: > > > On 2022-03-10 22:16 UTC+0100, Dan Ritter wrote: > > > nginx is just a web server, apache is just a web server.

Wayland vs X
I tried Wayland some years ago now (might have been when they first trialled it in Ubuntu) but decided not to stick with it. Since more desktop environments are beginning to choose Wayland as the default display protocol, I was wondering if others think there's significant user benefits to making the change? - Kevin
Hardware Acceleration on Chromium 99
Hi all, I'm running chromium 99 on Bullseye: Version 99.0.4844.51 (Official Build) built on Debian 11.2, running on Debian 11.2 (64-bit) And I can't get hardware acceleration working. I've followed the instructions here: https://wiki.debian.org/Chromium#Video_acceleration As well as a variety of other online sources of increasingly dubious quality, so I've decided to come to the mailing lists and plea for help. I'm running an Intel i5-5300U processor (so quite old I suppose): - Intel(R) Core(TM) i5-5300U CPU @ 2.30GHz with Intel Integrated graphics: - Intel(R) HD Graphics 5500 (BDW GT2) I've tried running it both with and without vulkan drivers enabled. I'm runnin Vulkan Instance: Vulkan Instance Version: 1.2.162 and some of the errors logs I'm getting particularly at startup look like this: *** stack smashing detected ***: terminated [32829:32829:0100/00.428969:ERROR:sandbox_linux.cc(377)] InitializeSandbox() called with multiple threads in process gpu-process. [32829:32829:0100/00.432878:ERROR:vulkan_device_queue.cc(227)] Vulkan: Intel(R) HD Graphics 5500 (BDW GT2) I'm checking to see if hardware accelerated video decoding is working by viewing this video in 1080p HD: https://www.youtube.com/watch?v=HmZKgaHa3Fg and looking at the output of intel_gpu_top, where the row for Video/0 stays at 0%. Anyone got any ideas? - Kevin <https://www.youtube.com/watch?v=HmZKgaHa3Fg>
Re: Offensive variable names [was: Cool down ...]
Right, and I myself have lodged a ticket to ban bar after foo because it might lead to blithe attitudes concerning alcohol in our vulnerable youth. Don't get me wrong: like many other things, offensive languages is a serious one. But, instead of helping, I think that you are in fact minimizing its gravity with such exaggerated actions. I guess my sense of humor may be a little too dry. Well, online communication can be easily misunderstood. That's why I added the "I still hope that you were joking though :)" part ;) Cheers, K.
Re: Offensive variable names [was: Cool down ...]

Don't get me wrong: like many other things, offensive languages is a serious one. But, instead of helping, I think that you are in fact minimizing its gravity with such exaggerated actions. I for one, have never in my life thought of alcohol when I saw a variable named "foobar". That is ... until I saw your post today :) . What's next? Should we also file a ticket to ban "chocolate bar". Or maybe we should ban mathematics completely from computing, since the "bar" symbol is a frequently used one there? https://mathworld.wolfram.com/Bar.html https://mathworld.wolfram.com/Macron.html Give today's youth a bit of credit. You might discover that they are smarter than you think. I still hope that you were joking though :) Cheers, K.

Debian switchable MTA mechanism
Hello Debian Users. Why Debian does't have a switchable MTA mechanism to allow install multiple MTAs at the same time? Fedora, Centos etc. allow users to install multiple MTAs at the same time. There's a "alternatives --config mta" command to allow to choose between alternative MTA. -- kevin

Looking for ratings of all-in-one printers for Linux (Ubuntu in particular)
I know there are probably multiple places where such ratings can be found. Not knowing which are reliable, I'm sort of asking for ratings of the ratings, I guess. Mostly, though, I want ratings of recent models, from a Linux/Debian/Ubuntu perspective as opposed to the usual Windows slant. I'm presuming the few machines that I dual-boot will be able to work with whatever printer I have. So, where to look? ++ kevin -- Kevin O'Gorman #define QUESTION ((bb) || (!bb)) /* Shakespeare */ Please consider the environment before printing this email.

Je ne sais pas si ce sera utile à la liste, mais je viens quand même de vérifier précisément : voici le menu lorsqu'on choisit le mode « expert install » : --- Menu principal du programme d'installation Debian : Choisir la langue Access software for a blind person using a braille display Configurer le clavier Détecter et monter le CD Charger des composants d'installation à partir du CD Détecter le matériel réseau Créer les utilisateurs et choisir les mots de passe Configurer l'horloge Détecter les disques Partitionner les disques ==>Installer le système de base Configurer l'outil de gestion des paquets Choisir et installer des logiciels Installer le programme de démarrage GRUB sur un disque dur Installer le programme de démarrage lilo sur un disque dur Continuer sans programme de démarrage Terminer l'installation Changer la priorité des questions de configuration Contrôler l'intégrité du(des) CD Sauvegarder les journaux de débogage Exécuter un shell (ligne de commande) Ejecter le CD du lecteur Interrompre l'installation --- Durant la 11e étape « Installer le système de base » lorsqu'on arrive à 72% de réalisation de cette étape, la ligne en bas de la fenêtre indique : « Configuration des sources d'APT ... ». Mais lorsque l'installation se déroule normalement, l'installeur *ne s'arrête pas* à ce moment-là --- l'arrêt suivant est celui du choix du noyau à installer--- même lorsqu'on est en « expert install ». Et on est bien toujours dans l'étape « Installer le système de base ». Dit autrement, « Configuration des sources d'APT ... » n'est ni un item du menu principal d'installation, ni même un des points d'arrêt à l'intérieur de l'tem « Installer le système de base » ; et durant une installation qui se déroule normalement, on ne voit cette étape que durant peu de temps. Donc je ne m'étais pas trompé dans ce que j'ai dit ; aucun mérite, j'ai eu maintes fois l'occasion de contempler longuement ce sous-titre : - ) Ce n'est pas très naturel --- au moins pour moi --- que la configuration des sources d'APT ne fasse pas partie de l'item suivant du menu, l'item « Configurer l'outil de gestion des paquets », avec lequel je suppose que tu as confondu, d'où ta question, non ? Merci pour tes explications et merci aux autres contributeurs qui m'ont répondu.

Il me semble qu'on n'a pas vraiment plus d'infos au sens strict, mais plutôt des choix plus détaillés. Mais les options « graphique » et « expert install » ne permettent pas de s'arrêter juste avant le blocage, ie avant la phase « configuration des sources d'apt », ce qui aurait été bien intéressant. Mon idée aurait été alors de sauter la configuration d'apt, installer grub, puis faire booter la machine sur cette install. Il y a peut-être une piste dans cette direction-là ? > - si ça ne suffit pas à résoudre ton problème: recommencer > l'installation puis tant que le CDROM est reconnu, basculer sur une > console (il me semble que par défaut la 2ème par CTRL-ALT-F2 est dispo > pour ça), taper mount pour voir où est monté le CDROM, poursuivre > l'installation jusqu'au problème puis rebasculer dans une console et > tenter de monter le CDROM là où il était monté précédemment) et en cas > de succès terminer l'install >
Re: blocage installeur debian : "please insert the disc"
Bonjour > > Je ne sais pas mais pourquoi ne pas tenter le dist-upgrade de squeeze > vers jessie puis jessie vers la version voulue? > > La liste exacte est squeeze < wheezy < jessie < stretch. J'aurais pu, dès le départ, dist-upgrader depuis la wheezy, en 2 étapes successives. De manière générale, je préfère les réinstallation à partir de rien. Depuis la squeeze, il fallait 3 étapes. Et d'autre part, l'installeur squeeze partitionne en ext3 et non pas en ext4 comme le font les distributions plus récentes. Je ne pense pas que l'installeur squeeze aurait accepté d'installer sur des partitions ext4 (que j'aurais créées au préalable), si ? J'ai l'impression qu'en partant de la squeeze, une piste intéressante serait, comme on me l'a suggéré, de modifier grub, d'installer l'iso de la stretch sur le dd (à la place du home ?), puis faire booter sur cette iso.

blocage installeur debian : "please insert the disc"
Bonsoir, tentative d'install de stretch sur un machine pas récente, un portable ACER Aspire 1641WLMi. Install par cdrom netinst (le bios de cette machine ne propose pas d'option de boot sur USB). Début d'install normal, accès au dhcp, accès à internet pour le serveur de temps ; vers la fin de l'étape « installer le système de base », alors que 72% de cette phase se sont déroulés sans pb (récupération, décompression, configuration de tout un tas de paquets), blocage sur le message : - [!!] Installer le système de base /media/cdrom: Please insert the dis labeled 'Debian GNU/Linux 9.3.0 -Stretch- -Official i386 NETINSNT 20171209-13:03' in the drive '/media/cdrom' ans press [Enter]. Media change - Appuyer sur l'un ou l'autre des boutons ne change rien. Le cdrom est bien dans son lecteur depuis le début de l'install. Même comportement avec des cd « netinst » pour buster, jessie, wheezy (gravés à vitesse lente) ; idem avec wheezy cd1 d'installation sans réseau Sortir le cdrom du lecteur avec un trombone (pas possible autrement), puis le réinsérer ne change rien. Changer de schéma de partitionnement ne change rien donc il semble que ce ne soit pas un problème de partition saturée. Juste avant tentatives de réinstall, la machine tournait très bien sous wheezy. Un vieux cdrom netinst de squeeze installe sans problème (tout en i386 si précision utile). Une idée de l'origine de ce blocage ?

Re: Re : RE: Re : Re: Ne trouve plus mon clavier
Bonsoir, je suggère de tenter de te logger sur ta machine debian HS (bootée) depuis une autre machine sur le même réseau, via ssh. Ce qui nécessite : => qu'un serveur ssh ait été installé sur ta debian HS (ce qui est, à mon avis, toujours à faire quand on installe, quitte à le désactiver après) => que tu connaisses l'ip de ta debian HS : si tu as une box, elle comprend un serveur dhcp qui attribue automatiquement une ip aux machines que tu lui connectes, donc : --> soit accéder à l'intérieur du serveur dhcp de la box pour voir quelle ip il a attribuée à qui,. (*) --> soit essayer en tâtonnant (si tu n'as que 2 ou 3 machines dans ton réseau local, ce sera vite fait). Par exemple, sur ton autre machine, sous linux, tu tapes « /sbin/ifconfig » dans un xterm et tu vas voir que l'ip de cette machine est, disons, 192.168.0.3. Il y a de grandes chances que ta box soit alors en 192.168.0.1 et tu cherches l'ip de ta machine plantée en pingant au hasard : « ping 192.168.0.2 », « ping 192.168.0.4 ». « ping 192.168.0.5 ». Si tu as une réponse, c'est qu'il y a une machine à cette adresse-là. Cherche une adresse voisine de celle de ta machine (si ta machine ok est en 192.168.0.32, alors essaie 31, et 33 par exemple. Pour te logger, attention, ne tente pas de te logger directement en root, logge-toi d'abord en utilisateur simple, puis passe en root (les connexions directement en root par ssh sont dangereuses donc probablement désactivées par défaut). Par exemple, supposons que tu aies eu une réponse positive au ping sur la 192.168.0.2, alors essaie : « ssh ton_nom_de_user@192.168.0.2 ». Pour la 1ere connexion, il va te demander de confirmer avant de te demander le mdp. (*) en général, c'est une manip du style : ouvrir ton navigateur (quel qu'il soit) taper dans la barre d'url l'ip que tu supposes être celle de ta box (ip sur ton LAN, bien sûr, pas celle attribuée par Orange ou ton fournisseur), disons avec mon exemple ci-dessus tu essaies l'ip 192.168.0.1 Si c'est la bonne ip, tu accèdes alors à la page d'accueil du petit serveur web qui est inclus dans ta box et tu cherches dans les pages.

Is bundled flash with chrome secure?
So I noticed the vivaldi thread said the latest flash version is 20.0.0.228 which is bundled with chrome and downloaded by the pepper downloader packages. I have had 267 appear in the home folder though but it cannot run. Since the time adobe dropped support, I only have had flash enabled on my myth tv box in google-chrome in /opt. I have home noexec and don't care for any comments as to WHY!!! and actually suggest script interpreters should respect noexec like the grsecurity patch enables!! Though I admit it can be handy to run a quick script and noexec still offers protection against non targetted attacks. What I would simply like to know (when I last checked google were keeping it secure) is whether the bundled 20.0.0.228 is secure. My hunch is currently not. Is an update due shortly and so I have just hit an insecure window? does it download a new version (267) to /home and can that location be changed can I check it's signature or does the browser do so at runtime, so I needn't check it and just copy it to /opt It always seems flash finds a way to be insecure... ahem out of date (it's always insecure) on all systems, I thought linux was different but maybe not?

Bonjour, Si ça peut aider... ces jours-ci, sur des machines installées en stretch, j'avais un problème avec LibreOffice base avec un fichier qui pourtant fonctionnait bien jusqu'à récemment --- quand exactement ? --- : lorsque je tentais d'ouvrir le formulaire, j'avais un message d'erreur : aucun pilote SDBC n'a été trouvé pour l'URL 'sdbc:embedded:hsqldb' -- Réinstaller le paquet « libreoffice-sdbc-hsqldb » n'a pas corrigé le problème. D'autre part, je voyais sur www que la version LibreOffice pour stretch est actuellement la 5, alors que mes machines sous stretch utilisaient toujours la 4 ; et une mise à jour classique (aptitude update / safe-upgrade) n'installait pas la 5. J'ai désinstallé le méta-paquet « libreoffice », puis je l'ai réinstallé (après avoir lancé un clean), et la réinstallation lance en réalité l'installation de la version 5 ; phénomène un peu curieux, que je suppose être lié à cette période de transition dont parle le post précédent. => et l'installation de la version 5 corrige mon problème d'accès à la bdd. Après la « réinstallation » du paquet libreoffice, un nouvel update/upgrade met à jour d'autres paquets (plutôt curieux aussi, puisque juste avant de désinstaller LO, j'avais lancé un update/upgrade).
Re: the State of Linux Audio
I read this with great interest because I lost sound some time ago and don't know anything about it, or how to control it. I'm running Xubuntu 14.04.4, on a brand-new ASUS Z97 Deluxe mobo, with both HDMI monitors and onboard Intel sound chips. The monitors have no speakers, so the HDMI channel is useless, but there are speakers connected to the mobo and /proc/sound/cards reports them as device 1. I hadn't heard a peep in ages unless I boot into Windoze, which plays sound just fine. So I ditched every installed package with pulse in the name where doing so did not threaten to remove the world. I tried an old mp3 file with the command aplay -D hw:1 -f S16_LE -c 2 -r 48000 longfilename.mp3 and got white noise -- the first peep I've heard in ages under Linux. It also reported Playing raw data 'longfilename.mp3' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo Can I do something to make this sound not white noise? What should I do next to get sounds to play normally? I'd be happy just to get system sounds to begin with.

McCormick a écrit : The only reason I put pulseaudio on here was way back when I was running lenny and had no /dev/dsp. Someone suggested installing pulseaudio. I did. /dev/dsp came back and life marched on. This was a bad suggestion. /dev/dsp is obsolete on Linux, has been for years. Not having is perfectly normal, having it back is possibly a sign that you are on the path of breaking things. In my opinion, PulseAudio is only good for messing things up. The features it brings are of doubtful usefulness for most users and the brittleness and complexity it introduces are very real. My advice is to get rid of PulseAudio as much as possible. You will not be able to get rid of the libraries if some packages use them, but make sure you purge the package with the daemon: in the past, just having it was enough to prevent sound playback from working. Then use low-level tools. To know if the cards are correctly detected, look in the file /proc/asound/cards. To hear if they work, use aplay -D hw:0 (or hw:1 for the second card). If the cards do not appear in /proc, this is a kernel problem and it must be resolved or there is no point of trying further. The aplay command I quoted does not do automatic conversions, that is on purpose. You will need to give it parameters supported natively by the hardware. With modern cards -f S16_LE -c 2 -r 48000 does the trick; aplay will give you hints. If you do not manage to get sound out of aplay, there is no point in trying anything else. If you do get sound out of aplay, then sound works. If anything fails to work and does not print any useful error message, try looking at the end of the dmesg output. Good luck.

If you don't mind the wait, this is much cheaper than buying from, say, Newegg. Since you specifically mention HBA preferably non-RAID, I'm not sure why you are asking for management software. I believe that's only useful if you're using the card's RAID functionality, which I don't. I use Linux md software RAID, with good results. Also, it is my understanding that all modern cards support drives larger than 2TB, it's the old DOS-style partition table that has the 2TB limit, and to create a partition greater than 2TB, you need to use GPT instead of MBR partition tables. That being said, I don't have direct experience with drives larger than 2TB. All the drives in my RAID are WD Red 2TB drives.

The key is getting a card that has chip(s) that are well supported by Linux. Deducing what chips are on a given card, and whether or not they are supported by Linux, for any given piece of hardware is something that I've yet to have much success with. So, I asked a similar question in July 2013: https://lists.debian.org/debian-user/2013/07/msg00310.html Basically, there were two choices: 1. 2 @ SATA2 host bus adapter ($20). 2. 4 @ SAS/SATA3 RAID controller ($200). I ended up going with the first option -- Syba SD-SA2PEX-2IR: http://www.sybausa.com/productInfo.php?iid=536 I'm not using it now, but don't recall any problems with Debian GNU/Linux, Windows XP, and the various free DOS versions used with Norton Ghost and hard drive manufacturer bootable diagnostic discs. I prefer PCIe x1 over PCI because PCIe should have faster access to the CPU/ chipset/ memory and because newer ATX/ microATX motherboards usually have at least one PCIe x1 slot; some don't even have PCI. As for SATA 1/2/3 speed differences on my SOHO network with LUKS encrypted drives, the bottleneck is usually the CPU (non-AES-NI) or the drive itself. At one point, I had a ZFS on Linux mirror on two 3 TB Seagate ST3000DM001's with LUKS on an Intel DQ67SW motherboard and Core i7-2600S processor, with one drive on a motherboard SATA3 port and the other on a motherboard SATA2 port. I recall that the drive on the SATA2 port had higher busy time than the SATA3 port, but the bottleneck was seeks. Thanks. I looked up Syba and found that board is now legacy, and I'm using only SATA III drives these days, so I found the current similar boards. I chose SI-PEX40062 which was the best fit for my drive needs and available PCIe slots (4 internal drives, 2x PCIe). Amazon had a board with the same model number and specs, but its brand name is IO Crest. I ordered it and it arrived today. It's working 50%. Ugh. Two of the four ports work fine. It happens that's all I _need_ to keep working, and I've started an RMA and order for a replacement, so that's okay -- it's time that's most important to me right now. At least there was no fooling around figuring it out. I can hot-swap the cables so long as no partition is mounted, so it was quick to determine that two ports work and two don't. My wife has Amazon Prime anyway, so the shipping is free and the replacement is coming even before the return has been sent (I'm using it in the meantime). I even get deliveries on Sunday because the USPS is trying harder. BTW, I'm interested in bus speeds this much because the drives are going to be doing huge sequential file accesses, and seeks are not an issue. I'm a lot happier than I was a week ago.

How to recover a damaged partition
I'm working with new 4TB drives, and one of them just had a bad spot in a fairly awkward place. The very first block of an ext4 partition was unreadable, and caused problems in booting, as well as anything else that wanted to scan partitions. I overwrote the first 4K with zeroes, deleted the partition (with gdisk) and created a new unformatted partition to cover the area. Now that partition passes a read test, and I'm checking the other partitions. The damaged partition has been inactive for a while, so I'm quite sure I have adequate backups. But now seems to be a time for me to learn -- lots of things have been going wrong, and I've been learning how to cope. So I wonder if there's a way to get that partition back, at least in part, without using my backups. Any hints, pointers, tutorials, or opinions welcome. -- Kevin O'Gorman #define QUESTION ((bb) || (!bb)) /* Shakespeare */ Please consider the environment before printing this email.

File system -- e.g. a copy of the files and directories on an mounted and operating drive. 2. Raw binary image -- e.g. a copy of the bytes on a drive taken when the drive is powered, but the partitions, volumes, file systems, etc., are not mounted. For system drives, the former won't work; you need the later. I connect a large hard drive (to hold the images), boot Debian installation media into rescue mode, and use 'dd' to backup/ restore system drive raw binary images. I was hoping for some details on why this won't work on system drives, or conditions under which it just might. Another user has suggested I read https://help.ubuntu.com/community/BackupYourSystem/TAR which suggests that it actually should work. Image backups are definitely easier for doing disaster recovery of an entire machine. And when you have that kind of problem, you may really appreciate having to do less work / make fewer decisions. But filesystems backups can be used for disaster recovery. I've done it. One potential problem is that on a running system, things change. So at the start of your backup, you backup file A. At the end of the backup, you backup file Z. But in the middle of the backup, both file A and file Z have changed. And some software requires that file A and file Z be in sync. When you restore, those files are not in sync and you could have a problem. In practice, I haven't seen this be a problem much on home desktop machines. But that's not to say it couldn't be a problem. Another thing to consider is hardware changes. This can make certain devices be named differently when you restore. eth0 becomes eth1, and /etc/network/interfaces doesn't have a stanza for eth1. /dev/dvd becomes /dev/dvd1, and your cd burner was set to look for /dev/dvd which no longer exists. These things can be fixed in the /etc/udev/rules.d directory. UIDs of disk partitions will change. If /etc/fstab references UIDs, you need to update it. Same for /boot/grub/grub.cfg, although for that you run update-grub2 from the restored system (you'll need to boot with a live cd and chroot, or you'll need to boot with Super Grub Disk or similar). You will also need to install the bootloader on the new hard disk. 'grub-install /dev/sda' The UUID and Grub issues don't show up when restoring from an image backup, but the network card and cd burner issues can. There are a lot of free software backup solutions available. I would recommend using one of those, unless this endevour is more for learning experience than anything else. Backuppc may be overkill for your case, but it's pretty good. It will do file pooling and compression, so keeping multiple backups of one or more machines doesn't take up much disk space. This is partly a learning experience, and partly to take control of what's happening. I have plenty of backup capacity. Aside from using compression I see no need to worry about optimizing storage. Instead, I like having each backup be self-contained and easily identifiable. I have roughly 32TB of 2-TB disks dedicated to backups (!) plus smaller older ones. My three machines are quite modest in size. Except for one with a huge stripe array for temporary stuff related to a hobby of mine, not subject to backups. I have backups running back for years, covering machines I recycled as much as a decade ago. All my drives are such that I have a USB drive dock for them, or they come with a USB interface. USB seems likely to stick around for a while. My hardware is stable enough I'm not worried about naming confusions. Almost everything is GPT partitions. Everything is identified by UUIDs -- those have no need to change and I know how to set them on an existing partition to match anything in /etc/fstab. I back up the GPT itself (both copies) and every partition other than swap. Just in case I want it later. I've not tried other solutions. I worry that the ones folks seem to like most do more than I need or want in terms of management. I want my stuff where I can see it, so to speak, and where I can use the ancient tools (tar, dd, gzip and so on) to work with it. I have already spent too much of my life dealing with incompatibilites, problems with software and format changes and a whole raft of other stuff. I want it simple, and I want it to be obvious. I use directory and file names to help make it so, and every backup includes the scripts that were used to make it. It's all bash script and tools that were known at the time I started using Linux -- roughly 1993. I'm a bit ashamed I've never tried (or needed) a system restore before. So whatever this problem is, it's probably lurking in all of my
An experiment in backup
I'm trying to develop a reliable backup method that does not use proprietary tools or formats, and is free as in beer. I thought I had it, but i just tried a restore, and it's a miserable failure. I wonder if anyone here can point out the error of my ways. I have a tar backup of the entire system, excluding /sys, /proc and /dev. I have a tar backup of a bind-mount of /dev. These were taken while the system was running, but quiet. I did it this way because I cannot get the system to boot into single user mode. Putting single on the end of the linux like results in a black screen. I restored these, created /sys and /proc, and tried to boot the resulting partition. It boots, but X does not come up, or even seem to try. I can do a console login to my usual account, and stuff is there. I'm quite clueless as to why this is happening. I could sure use some help. -- Kevin O'Gorman #define QUESTION ((bb) || (!bb)) /* Shakespeare */ Please consider the environment before printing this email.
