[OFF-TOPIC] Proxmox vmbr0 sobre bond0 problema interfaz veth openvz
Hola muy buenas y feliz año a todos antes de nada. Quería comentaros un problemilla que aunque está fuera un pelín de la lista de Debian, no deja de ser interesante y además proxmox está basado en debian.. El caso es que he creado una interfaz bonding con el algoritmo round robin con 4 tarjetas: Bonding Mode: load balancing (round-robin) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: c4:34:6b:b6:5c:d0 Slave queue ID: 0 Slave Interface: eth1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: c4:34:6b:b6:5c:d1 Slave queue ID: 0 Slave Interface: eth2 MII Status: up Speed: 100 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: c4:34:6b:b6:5c:d2 Slave queue ID: 0 Slave Interface: eth3 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: c4:34:6b:b6:5c:d3 Slave queue ID: 0 Con esta configuración de red: # network interface settings auto lo iface lo inet loopback iface eth0 inet manual iface eth1 inet manual iface eth2 inet manual iface eth3 inet manual auto bond0 iface bond0 inet manual slaves eth0 eth1 eth2 eth3 bond_miimon 100 bond_mode balance-rr auto vmbr0 iface vmbr0 inet static address 192.168.0.33 netmask 255.255.255.0 gateway 192.168.0.1 bridge_ports bond0 bridge_stp off bridge_fd 0 Como véis tengo creado la interfaz bridge vmbr0 sobre bond0 para compartir vmbr0 a las máquinas virtuales KVM u openvz. Openvz tiene 2 maneras de crear interfaz de red, usando venet y usando veth. Usando venet es prácticamente enrutamiento y no hace falta tocar ni si quiera en el container el fichero /etc/network/interfaces , pero necesito una interfaz veth. Cuando creo una interfaz veth para el container o una interfaz para KVM usando el bridge vmbr0, configurando la red y demás, soy incapaz de tener tráfico en la máquina KVM u openvz... No sé por qué puede ser la verdad. En teoría lo estoy haciendo bien. Al hacer un vmbr0 sobre una sola interfaz, por ejemplo eth0, funciona sin problemas. He mirado en la documentación de proxmox antes de postear aquí y no he visto nada adicional que tenga que meter para tener tráfico usando vmbr0 en las VMs sobre bond0. Alguien sabe si he realizado algo mal o por qué no tengo red? No sé si me puede estar faltando alguna famosa regla de iptables...

Raid por hardware intel rapid storage technology en Debian
Hola buenas, recientemente he adquirido este portátil de segunda mano: http://www.sony.es/support/es/product/VPCZ21C5E En la web de sony de ese modulo por supuesto no hay nada de soporte para linux. Me he fijado y tiene dos discos duros ssd de 128 GB. Mi idea era crear un raid 0 usando la utilidad intel rapid storage technology, y desde linux ver un solo disco duro e instalar el SO ahí pero la verdad me está volviendo un poco loco...Veo el volumen que creo de raid0 en /etc/mapper/Volume0 pero no me deja hacer nada con él. Si hago un fdisk -l me aparecen los 2 discos duros ssd... Creo que estoy obligado a borrar el raid y a usar mdadm... Qué opináis?

Re: [OT] Raid por hardware
El Mon, 12 de Jan de 2015, a las 02:39:28PM +, Camaleón dijo: Mucho esperas... Me extrañaría que tuviera memoria flash con capacidad suficiente para albergar los datos más allá de los que necesita (firmware y metadatos). Salvo que la controladora sea buena (pero de las buenas de verdad que tienen un batería y todas esas gaitas) y aún así tendría mis dudas. Pues creo que llevas razón. He comprobado el driver que hay cargado en el ordenador suplente temporal, que no lleva ninguna controladora RAID, y se carga el driver mptctl. Entiendo que es este driver el que me oculta que el disco tenga metadatos del RAID y que haciendo una consulta a las particiones y demás parezca un disco normal, ¿no? Es que no tienes más que una controladora de disco sata y es la LSI. He estado consultado la BIOS del servidor desmantelado. La controladora se puede poner como: + IDE, que era como estaba. + ACHI. + RAID y dentro de esta categoría: - Intel no se qué (entiendo que será un fake-raid) - LSI, que utilizará la controladora RAID pinchada. Lo he puesto en ACHI y con el segundo disco he probado a instalar un paquete. No ha parecido demorarse como antes, pero no me fío mucho. No sé si probar a ponerlo en ACHI o en RAID-LSI y probar. Lo que me escama es que la BIOS estuviera en IDE y no en LSI: yo no he tocado nada. A lo mejor se desconfiguró cuando actualicé la BIOS (aunque tampoco sé cuál era su valor antes de la actualización). El problema que tengo ahora es que no sé cómo narices identificar uno de otro disco para que el disco que ha estado esta semana trabajando sea el disco primario del RAID. Debería haber una forma, pero soy incapaz de verla. Al menos mientras el RAID estuvo montado: a lo mejor sí se puede ver al crear el RAID. Como ya he visto que el sistema en el ordenador funciona sin problemas, lo haré la semana que viene. Con suerte ha desaparecido el problema, aunque no sé muy bien cuál podría ser. La memoria la testeé y estaba bien. :/ Saludos, Saludos. -- El amor es como los columpios, porque casi siempre empieza siendo diversión y casi siempre acaba dando náuseas. --- Enrique Jardiel Poncela --- -- To UNSUBSCRIBE, email to debian-user-spanish-requ...@lists.debian.org with a subject of unsubscribe.

Re: fail2ban
Les règles sont réenregistrées autant de fois qu'il y a de RETURN. Et ça enfle. J'ai relancé fail2ban hier soir, ce matin, j'ai déjà quatre RETURN par règle. Ce soir, j'en aurais certainement une bonne quarantaine... L'augmentation se fait bien un par un. La logique tient peut-être au fait que f2b doit écrire une nouvelle règle pour chaque IP bannie.

Hi Kevin, If you copy the whole partition, byte-for-byte, as with the 'dd' command, you copy everything, including the free space. If you copy via the filesystem, e.g. using rsync, you just pay for what you use, and all the files are immediately available. Restoring a file is a matter of copying. My big files are video, which don't compress well, and I backup to disk, not tape, so I see no benefit from using tar. btw, like many others, I've written various backup scripts over the years. Lately, I've just done full backups, one for /home, one for everything else. My case is simple, because everything is in one partition. I exclude some directories, and after making the backup, create them in the backup directory. #!/bin/sh RSYNC=rsync -avx CMD=$RSYNC \ --exclude /dev \ --exclude /proc \ --exclude /sys \ --exclude /home \ --exclude /tmp \ --exclude /var/cache/apt/archives \ --exclude /var/run \ / /mnt/$1/root echo $CMD /var/log/backup.log for dir in dev proc sys home tmp var/run var/cache/apt/archives ; do mkdir /mnt/$1/root/$dir; done This script doesn't address permissions. (/tmp usually gets 1777.) I haven't tested it lately. However you can see to work if /dev /proc and /sys get populated on boot, you should have everything you need. The most likely booting issues for me are usually something in /etc/fstab.

problem that prevents aplay from running when the PCM device is specified and
the above solution may still help you.

Latest update was bad news for me!
I've got an ASRock motherboard with AMD AM3 CPU and Giga PHY RTL8211CL ethernet, running Wheezy. Had no joy getting the network port running (forcedeth module would kill the whole system as soon as tried to use or even unload it!), so I used an old (faithful) DEC Tulip card (de2104x module). And so it ran for months (or a year or more, through a number of linux updates) without problems. Last week I happened to find a reference in an Ubuntu forum to successfully getting the RTL8211 working - after consultation with ASRock. It involved removing the forcedeth module and reinstalling it with certain parameters. So I tried it, and it worked (without killing the system!); I put the necessary fix in a file in /etc/modprobe.d, and that I used until this morning. I presumably had rebooted in that time to test the fix. This morning the latest Linux security update (DSA3128) arrived and I installed that. It involved a restart, after which I had no network connection - not even with the Tulip card. In fact I was back to rmmod forcedeth killing the system (with a familiar pattern on screen - but locked SOLID). No, I have not been able to get the Tulip working in Wheezy, but I know it is not dead - Puppy Linux (tahr) gets it going just fine (but has other problems apparently from the RTL8211 which it can't connect to the network). After some hours of frustration, I have got the RTL8211 working in Wheezy, but it seems to involve manual loading of the forcedeth driver after every restart. One thing to take from this - ASRock, AMD AM3, and Linux don't play well together. Another is that today's de2104x module doesn't work my card. /vent Bruce Ward -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

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. Skip these. /sys and /proc are pseudo-filesystems in that they are representations of kernel settings in a file system format. Some of these files are read only (for example the contents of /proc/net/dev are statistics on all your network devices; in this case, it makes no sense for userspace to be telling the kernel how many packets have been recieved, so you can't write to the file), some of the files are write only (for example /proc/sysrq-trigger which can be used to simulate pressing SysRq+something). And besides, neither of these filesystems is persistent (the contents are lost at shutdown and recreated when the filesystem is mounted). /dev, similarly, is (since the days of devfs) a dymanic filesystem containing only communication end-points to your devices. You could back up the device nodes, but because the kernel autodiscovers hardware and creates the devices nodes at boot, you'll either have exactly the same thing (if the autodetection happened in exactly the same manner) or the WRONG device nodes.

I haven't investigated that far. I'm just stating a fact.
I don't know what's the purpose of pulseaudio nor what are the benefits of
having installed it. I don't know if it would break something to remove it.
I believe it was installed at some point as part of a routine system update
and may have been the cause of the sound failure in the first place.

Hi Kevin, If you copy the whole partition, byte-for-byte, as with the 'dd' command, you copy everything, including the free space. If you copy via the filesystem, e.g. using rsync, you just pay for what you use, and all the files are immediately available. Restoring a file is a matter of copying. ... #!/bin/sh RSYNC=rsync -avx CMD=$RSYNC \ --exclude /dev \ --exclude /proc \ --exclude /sys \ --exclude /home \ --exclude /tmp \ --exclude /var/cache/apt/archives \ --exclude /var/run \ / /mnt/$1/root echo $CMD /var/log/backup.log I can confirm that the above works. I recently used rsync to copy my live system to another partition, excluding /dev /proc /sys /tmp and /home. After setting grub to boot the new partition, it works fine.

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. -Rob signature.asc Description: Digital signature

Sleep but no resume
Running stable 64bit with the 3.2.65-1+deb7u1 kernel. This macbook will go to sleep but will not resume, requiring a hard reboot. When s2ram is run, the acivity light blinks- a sign that the machine is really asleep. However, when I hit a key, the light goes out and no resume. I booted into OSX and sleep/resume was flawless, so it’s not hardware. Resume worked before the recently updated proprietary nvidia driver. So, uninstalled it and ran with nouveau, but still nogo. I then installed a newer proprietary from backports. No resume still, so it doesn’t seem to be a driver problem. I've googled a lot and looked through files I never heard of before but couldn't find anything helpful. Bug #774461 refers to a fix for a similar but really different problem, and says that sleep/resume is fixed with the kernel I’m already running. I’ve run s2ram wth different parameters but got nowhere. Finally, s2ram --test returns Machine unknown This machine can be identified by: sys_vendor = Apple Inc. sys_product = MacBook5,1 sys_version = 1.0 bios_version = MB51.88Z.007D.B03.0904271443 I’m at a loss here.

Hi Ric, it's getting weirder: I installed pavucontrol, started it, and started mplayer in some other window. No sound on my headphones, but the little VU bar flashing. Unplugged headphones, sound came from the built in speaker. Plugged headphones back in, pavucontrol sees it and changes from unplugged tp plugged in, still no sound on headphones. With aplay -D hw:0,0 it still works. OK, now trying to remove all pulse-related stuff. You're shooting yourself in the foot. IF alsa won't work, pulse will not either. IF you used pavucontrol, set up your sound sources, then selected playback while the file was playing, you should have seen the volume bar twitching. If it was, did you check to see if the volume was scrolled up to 100%, unmuted, and that the headphone was selected?? Or, is this some headphone plugged into the soundcard audio-out jack? Maybe you're plugged into audio-out (which is non-amplified) instead of the headphone jack, which is? OR if there is just one output jack, which relies on some sort of hardware magic to determine if it should act like audio-out/headphone out, there in lies the problem. PLugging in the headphone, removing it and pugging it in, multiple times might get it to switch correctly. They don't always work right. Get a cheap set of USB headphones and suffer no more. Leave the sound card to drive speakers, which worked, as you mention. That must be the problem as I had that happen trying to plug in some earbuds. The audio-out expects the plugged in device to have it's own amplifier. Headphone out uses the sound card amplifier to drive a non-amplified device, like old headphones. No sound indicates you're in the wrong jack or it fails to auto-select/switch between the two states if there is only one out jack. I bet this is the problem. Refer to your manual if you have it.

How would an application that wants to play sound figure out which system to use? There are several people more knowledgeable than me around here, but, AFAIK, alsa is the lowest level sound manager. If I am not wrong, pulse audio is built on it. Note that I never tried PA: alsa always worked just fine for me, so why should I try it? I understand the linux Audio stack like this: Alsa == OSS ^ | ^ / \ PA J Alsa is better (why? No idea, just what people says...) than OSS, and then you have 2 frameworks which works over Alsa. PulseAudio (PA, which seems to be POSIX and windows compatible), and Jack (J, which seems to be used by professional applications, for real-time stuff and other. If you simply want sound from flash-player, iceweasel and mplayer... well, removing PA may help you, and it will remove something you do not necessarily need. And, in my opinion, less code running on my computer means less surprises (on my computer), so it's the way I choose. But, I am a minimalist lover (well, at least in computing... for beers per example I have different tastes ;) ). Note that I have no opinion about the quality of pulse audio and jack. Plus, in some cases, I had problems with microphones with Alsa. Maybe in those situations PA or jack would have helped me. Never tried, it was not important enough for me. Maybe if the OP mv;d that file to another name, rebooted and ran alsamixer first, then add pavucontrol along with pulse, he might have a better experience, IMHO. I'll try that (have to install first). If it works, can I then purge all ALSA-related stuff from my system? Or could I also remove all pulse-related stuff and keep ALSA? If you purge alsa-related stuff, you will end with no sound at all. Alsa means Advanced Linux Sound Architecture. It seems to be a driver replacement for OSS. In short, it would be like removing your nouveau/nvidia/intel/whatever driver and trying to run Xorg or weston... Xorg and weston would be PA and Jack, the driver would be alsa. That's what I understand, at least. Jack confuses the heck out of me, and I think it relies on a realtime kernel. I leave that to the true audiophiles who need that degree of response for mostly sound only applications. You are right, alsa is a must have installed.

Greetings, back on the old 10.04.4 LTS LUCID drive. Ric, installing that mesa library for firefox made firefox work better, no squawking about the missing file. But, it pulled in 19 other packages either for additional deps, or whatever, then finished up on a rescan, wanting to update about 100 other packages. Which I didn't let it do. However, when I went to reply to the mail, I fond that in addition to wanting to remove kmail without replacing it with an even newer version, whatever it pulled rather instantly removed kmails ability to send mail, claiming the address was bogus. But it never had time to ping the mail server, it was an instant rejection. So now I am back on the old LUCID based install. Where hopefully I can send an email. With kmail.

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.
