El sitio al que realiza la peticion es: 1260365456.470 122021 172.16.0.123 TCP_MISS/500 1424 GET http://bosnjaci.net/ - DIRECT/98.131.190.168 text/html imaginen esa linea en su access.log pero 500 mil veces en solo unos minutos La pregunta es hay alguna manera de evitar que alguna maquina infectada pueda causar la saturacion del squid, por que ya esta hecha la recomendacion a los usuarios pero nunca faltara alguna marciano que se cuele por ahi con ese virus. Quiero ver si del lado del servidor hay alguna manera de proteger de dicho ataque, por que en realidad lo que se satura es el squid, por que probe un equipo directo al modem y si habia respuesta a cualquier pagina...

[CentOS] XFS and LVM2 (possibly in the scenario of snapshots)
Hi list, during the last days there was a discussion going on about the stability of XFS; though I myself used XFS heavily and didn't run into issues yet, I'd like to ask something *before* we create our next generation data storage backend... Les Mikesell wrote in [0] about issues in the combination of XFS and LVM -- however, it was being discussed in context of using 32bit kernels. What I specifically need is to run XFS (or something similar, I am *not* forced to use XFS, but it was my preference for some years now, and I didn't have any issues with it yet) on top of LVM to be able to create snapshots. We're talking about several file systems of a size at about 4TiByte each. On another place [1] I read that there were issues with that. Can anyone shed some light on this? Would be very appreciated.

Re: [CentOS] VirtualBox and CentOS
I tried everything in that post as well, and nothing worked for me. Finally I found the process I laid out and it worked. The link to it is here which is an old ticket: http://www.virtualbox.org/ticket/705 I've tested it and it works! Presumably, it might have worked in some of my previous attempts, but I only now figured out that I need to manually attach the device via device menu or USB icon. Not exactly plug and play, but workable. The mount command itself is sufficient here, no need to stop vboxdrv (or vboxnet, which doesn't exist), or chmod g+rw /dev/vboxdrv.

Les Mikesell wrote in [0] about issues in the combination of XFS and LVM -- however, it was being discussed in context of using 32bit kernels. What I specifically need is to run XFS (or something similar, I am *not* forced to use XFS, but it was my preference for some years now, and I didn't have any issues with it yet) on top of LVM to be able to create snapshots. We're talking about several file systems of a size at about 4TiByte each. On another place [1] I read that there were issues with that. Can anyone shed some light on this? Would be very appreciated. There is no problem if it is done on x86_64 with it's 8k stack frames, but on i386 with it's 4k stack frames you could run into a stack overflow when doing it on top of stackable block devices (md raid, lvm, drbd, etc). Also since the current LVM on CentOS doesn't support barriers (next release I believe) journalling isn't safe on LVM unless you are using a storage controller with BBU write-back cache. I have heard anyways that the current implementation of barriers isn't very performant and doesn't take into consideration controllers with BBU cache, so most people will end up mounting with nobarriers which just means they are in the same boat as they are now. Better make sure your machine is bullet proof as a power outage or a kernel panic can spell disaster for XFS (or any other file system really). It is better to invest in a good hardware RAID controller until the whole barriers stuff is ironed out. It should really perform better then it does. Thanks for your detailed explanation, that really clears things up; however, I was intending to build a software RAID10 as we had really not so good experiences on hw RAID controllers int the past (for all kinds of phenomena). Would barriering here still be a problem then? So long as LVM isn't involved it will use barriers, but I can tell you you will be less then impressed by the performance. Go for hardware RAID with BBU write-cache, go for a good hardware RAID solution, look to spend $350-$700 get one that supports SAS and SATA. I like the LSI MegaRAID cards with 512MB of battery backed cache. Some cards allow you to run in JBOD mode with battery backed write- back cache enabled, so if you really want software RAID you can run it and still have fast, safe performance (though you spread the cache a little thin across that many logical units). -Ross ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

However, and this is a big but: $ sudo rpm -ivh google-chrome-beta_current_x86_64.rpm Password: warning: google-chrome-beta_current_x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 7fac5991 error: Failed dependencies: lsb = 3.2 is needed by google-chrome-beta-4.0.249.30-33928.x86_64 xdg-utils is needed by google-chrome-beta-4.0.249.30-33928.x86_64 $ yum list | grep -i lsb redhat-lsb.i3863.1-12.3.EL.el5.centos installed redhat-lsb.x86_64 3.1-12.3.EL.el5.centos installed I'm not that familiar with lsb, but from what I can find, it does not seem like it would be a good idea to install a more recent version of lsb than the official release, or am I way off base here? I can get xdg-utils easily enough, but it doesn't seem relevant if I can't use the newer lsb. So, is it possible to use lsb 3.2+ on CentOS 5.4 without breaking anything? Is there anything else I'd need to do, other than convert to Fedora (not going to happen)? Thanks. mhr ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] find latest version of rpms from a mirror
I want to write a script to find the latest version of rpm of a given package available from a mirror for eg: http://mirror.centos.org/centos/5/os/x86_64/CentOS/ Is there any existing script that does this? Or can someone give me a general idea on how to go about this? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Les Mikesell wrote in [0] about issues in the combination of XFS and LVM -- however, it was being discussed in context of using 32bit kernels. What I specifically need is to run XFS (or something similar, I am *not* forced to use XFS, but it was my preference for some years now, and I didn't have any issues with it yet) on top of LVM to be able to create snapshots. We're talking about several file systems of a size at about 4TiByte each. On another place [1] I read that there were issues with that. Can anyone shed some light on this? Would be very appreciated. There is no problem if it is done on x86_64 with it's 8k stack frames, but on i386 with it's 4k stack frames you could run into a stack overflow when doing it on top of stackable block devices (md raid, lvm, drbd, etc). Also since the current LVM on CentOS doesn't support barriers (next release I believe) journalling isn't safe on LVM unless you are using a storage controller with BBU write-back cache. I have heard anyways that the current implementation of barriers isn't very performant and doesn't take into consideration controllers with BBU cache, so most people will end up mounting with nobarriers which just means they are in the same boat as they are now. Better make sure your machine is bullet proof as a power outage or a kernel panic can spell disaster for XFS (or any other file system really). It is better to invest in a good hardware RAID controller until the whole barriers stuff is ironed out. It should really perform better then it does. Thanks for your detailed explanation, that really clears things up; however, I was intending to build a software RAID10 as we had really not so good experiences on hw RAID controllers int the past (for all kinds of phenomena). Would barriering here still be a problem then? So long as LVM isn't involved it will use barriers, but I can tell you you will be less then impressed by the performance. Go for hardware RAID with BBU write-cache, go for a good hardware RAID solution, look to spend $350-$700 get one that supports SAS and SATA. I like the LSI MegaRAID cards with 512MB of battery backed cache. Some cards allow you to run in JBOD mode with battery backed write- back cache enabled, so if you really want software RAID you can run it and still have fast, safe performance (though you spread the cache a little thin across that many logical units). Thanks for your eMail, Ross. So, reading all the stuff here I'm really concerned about moving all our data to such a system. The reason we're moving is mainly, but not only the longisch fsck UFS (FreeBSD) needs after a crash. XFS seemed to me to fit perfectly as I never had issues with fsck here. However, this discussion seems to change my mindset. So, what would be an alternative (if possible not using hardware RAID controllers, as already mentioned)? ext3 is not, here we have long fsck runs, too. Even ext4 seems not too good in this area... -Ross Timo ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Well, for me the recommended LSI is okay as it's my favorite vendor, too. I used to abandon Adaptec quite a while ago and my optinion was confirmed when the OpenBSD vs. Adaptec discussion came up. However, the question on the hardware RAID's vendor is totally independent from the file system discussion. I re-read XFS's FAQ on this issues, seems to me that we have to set up two machines in the lab, one purely software RAID driven, and one with a JBOD configured hardware RAID controller, and then benchmark and stress testing the setup.

If you use hardware raid, you do not need barriers and can afford to turn it off for better performance or use LVM for that matter.
