Re: [CentOS-virt] VirtIO disk 'leakage' across guests?
On Mon, January 16, 2012 13:05, James B. Byrne wrote: How is it even possible for an application running under a httpd service on one guest to see anything at all besides the VirtIO storage assigned to that guest? Has anyone else encountered this anomaly? I just cloned a guest instance. The clone prototype was set up with a single VirtIO disk of 8Gbs, divided into a 500 Mb boot and a ~7.1Gb root partition. The root partition was entirely assigned to the basic vg and two lv were created, one for swap and one for the actual root partition. When the guest was cloned there was only one VirtIO disk of 8 Gb assigned to it and this was cloned and given a new name.

Re: [CentOS-virt] VirtIO disk 'leakage' across guests?
This behaviour has to be related to the fact that the volume group name does not change when guests are cloned. I do not know where the confusion originates but doing xmldumps from virsh shows that all of the guests only have their own VirtIO disks assigned to them so the cross linking is happening elsewhere and the vg name seems the likely place. However, I am at a loss as to how to avoid this. It does not appear that an option to rename the volume group is given when cloning from virt-manager. Is there a way to do this when the guest is cloned? -- *** E-Mail is NOT a SECURE channel *** James B.

All of the guests, without exception, have been cloned brom a prototype guest using virt-manager. All of the additional VirtIO disks assigned to some of the guests have been added through virt-manager as well. Recently I have encountered a situation with the development copy of Webmin where I can see an additional VirtIO disk assigned to one guest instance, but not yet added to the lvg of that guest, as an unknown device on different guest. Further, I can see an lv assigned to one guest instance as an lv on a difference guest. The webmin author is aware of this problem and is assiduously trying to determine its cause. My difficulty is answering the question: How is it even possible for an application running under a httpd service on one guest to see anything at all besides the VirtIO storage assigned to that guest? Has anyone else encountered this anomaly? Can you share the (vg|lv|pv)display on two such guests that allegedly share a disk? A dumpxml and lvdisplay of the host side of there two guests would be useful too. The only case where I have seen stuff like this was when someone was using unpartitioned virtual disks as physical volumes in the guests which resulted in the host picking up the metadata and discovering the vg/lv/pv data of the guests on the host side. What a mess that was. Regards, Dennis ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

Tengo actualmente 2 líneas contratadas y tengo un servicio dns que apunta a una de ellas. Digamos que la linea 1 es la que resuelve el dominio dominio.com. Mi duda surge, cuando quiero que por ejemplo si se cae la linea 1, automáticamente el dns apunte a la linea 2 y por lo tanto sigan funcionando los servicios. Alguiene tiene alguna idea o se ha topado con éste problema? No sé si habrá proveedores de internet para dns que lo hagan.

Re: [CentOS-es] Resumen de CentOS-es, Vol 61, Envío 14
Yo alguna vez tuve que resolver algo así! Pero antes de poder resolver el problema del dns hay que aclarar unas dudas. ¿El servicio DNS que tienes ... lo presta un equipo que opera dentro de tu red local? De ser así, hay un inconveniente, por que de caerse tu linea 1, ya nadie podra resolver nombres con tu servicio a menos que el servicio DNS que entrega el ISP este configurado de tal forma que las consultas se puedan transmitir tambien por la linea 2; el punto es el siguiente. Si ambas lineas te las suministra el mismo proovedor, estamos seguros de que si se cae la linea 1, la linea 2 tambien estara abajo. Lo ideal seria que ambas lineas pertenecieran a diferentes proovedores y ademas contratar un servicio ADSL o si tienes mas recursos un enlace dedicado para tu propio Servidor DNS con un proovedor tambien diferente, y en este servidor, modificar la configuración del servicio agregando las direcciones IP que corresponden a cada proovedor del servicio con tiempos de refresco intermitentes. Un ejemplo: Usando Bind (servidor DNS Linux) para el mismo dominio con dos proovedores diferentes: dominiox xxx.xxx.xxx.xxx (direccion IP entregada por el proovedor 1) 0.5 seg de refresco dominiox yyy.yyy.yyy.yyy (direccion IP entregada por el proovedor 1) 0.5 seg de refresco de esa forma tu servidor dns responderá con la direccion del equipo al que llega cada peticion. es una forma un tanto tediosa de realizarse pero así aseguras tu servicio a nivel de disponibilidad y tu mantienes el control absoluto de las configuraciones para casos de emergencia y no dependes de que tu proovedor deba modificar parametros en sus servicios (que de por si son considerados una larga espera que puede costar unas cuantos miles de dolares si estas entregando un servicio). Espero haber sido de ayuda.

If you add a

gen_requires(`

role system_r types xauth_t;
It should fix the first problem, not sure the other two are important.

[CentOS] bounties for exploits against CentOS?
With companies like Facebook and Google offering cash prizes for people who can find security holes in their products, has there ever been any consideration given to offering cash rewards to people finding security exploits in CentOS or in commonly bundled services like Apache? (Provided of course they follow responsible disclosure and report the exploit to the software authors and get it fixed.) Obviously the benefit would be that it would increase the chance of a white hat finding and fixing an exploit, before a black hat discovered the same one and used it to attack people's servers. Would there be any other downsides, other than the cost of paying out the prize? I've heard some objections from companies over the years who didn't want to institute a prize program, but I thought some of those objections didn't make much sense (and indeed some of those companies ended up instituting a prize program after all, a few years later). For example, some people said, This just encourages people to find exploits and then they might use those exploits to do harm. (The problem with this is if someone has sufficient black-hat incentives for finding an exploit -- either to do malice, or more likely to sell it on the black market -- those incentives *already* exist, so the prize program wouldn't create any additional incentive to use an exploit illegally.) Would you feel safer using CentOS if a bounty program encouraged people to report exploits to the project? Why or why not? I think I would, for the stated reason -- newly discovered exploits are more likely to get reported and fixed, than to be used in the wild. But I'd be curious why anyone might feel less safe if such a program existed. On a related question, suppose that instead of paying for generic exploits against the operating system, you as a webmaster had the option of adding your website to a directory of bounty sites, where you would have to put up a bond of $100 to join. Then anyone who could prove that they broke into your server (let's say the proof is that they read a world-readable file in the root directory) would collect the $100 prize, if they can describe exactly how they did it and what you need to fix to prevent the attack in the future. That way, if there's ever a weakness in your server, it's more likely to be found by a white hat and reported to you directly so you can fix it, before a black hat finds the same weakness. Would you sign up your webserver? I think I would, and I believe I'd be reducing the risk of a black-hat breakin as a result, but there may be counter-arguments that I'm not thinking of.

The root partition was entirely assigned to the basic vg and two lv were created, one for swap and one for the actual root partition. When the guest was cloned there was only one VirtIO disk of 8 Gb assigned to it and this was cloned and given a new name.

Re: [CentOS] VirtIO disk 'leakage' across guests?
This behaviour has to be related to the fact that the volume group name does not change when guests are cloned. I do not know where the confusion originates but doing xmldumps from virsh shows that all of the guests only have their own VirtIO disks assigned to them so the cross linking is happening elsewhere and the vg name seems the likely place. However, I am at a loss as to how to avoid this. It does not appear that an option to rename the volume group is given when cloning from virt-manager.

It would be nice to experiment, but I am out of time. I did fdisk -l /dev/sda file and I can do dd to image file, but how about resizing/repartitioning?

There are so many firewall distros to choose from. FireStarter, IPCOP, etc. The box I was going to use is a P4, 3GB RAM, 3 GB NICS. I could always use a beefier box also if there was really a need to for such a task. I am used to some Cisco PIX boxes and they just seem fast on hardly any specs.

[CentOS] Mic Plugged into sound card not working
Hey guys, I have a mic plugged into my sound card. It worked late last night but not today. When I try to select the mic using System/Preferences/Sound I'm provided with several options to choose from. On the Hardware tab I choose the Internal Audio device and set it to Analog Stereo Duplex. On the Input tab I choose Internal Audio Analog Stereo there are two Analog Microphone Inputs, 1 and 2, to choose from. Each of those inputs has Microphone 1 and 2 to choose from. When I try to record from the mic in Audacity I get a flat signal if I choose Input 1 no matter which Microphone, 1 or 2, I choose. If I choose Input 2, no matter which Microphone I choose, the wave form freezes until I return the selection to Input 1. alsamixer -c0 does not indicate any input settings being muted. In fact its indications change in response to changes in Sound Preferences and Sound Preferences indications change in response to changes in alsamixer -c0.

Others have already pointed out that CentOS is multiarch and that you can install i?86 packages in parallel to the basic x86_64 arch packages. If the script you are running is hardcoded to require ia32-libs, then that install method is not compatible with CentOS. You probably will have to read the script's code to see whether it fits CentOS.
