desde hace varios dias con un progra que se llama flood.tgz, esto lo que me parece es que monta al parecer un robot para mandar mails y otras cosas, el ataques es haciendome syn flood y DDoS. Es lo que parece que hace este programa, se me olvidaba el programa lo montan en : /temp o en /var/tmp y montan otro archivo en /var/spool/crond/ entonces no te están atacando, te están usando el servicdor para atacarte. los ataques a servidores son muy comunes estos días, lamentablemente cierto. Afortunadamente te has dado cuenta de que te han atacado el servidor y ahora te sugiero que determines por dónde entraron, trates de corregir ese problema y de paso procedas a actualizar el servidor si el ataque no fuera tan grave. simplemente reinstalar sin determinar por dónde entraron es llamar a que el atacante entre de nuevo. saludos epe Quisiera saber que puedo hacer para evitar este ataque.

[CentOS] How to copy a system?
Is there a standard way of copying a working system from one machine to another with different partitions? I have two CentOS-5.6 machines, say A and B, and I thought I would copy / on sdb10 on machine A to an unused partition sda7 on machine B with rsync. I made the appropriate changes to /etc/fstab and grub.conf , as well as /etc/sysconfig/network-scripts , but found that there were innumerable errors when I booted machine B into the new system, mostly to do with creating dev's. Also the ethernet connection, which had been eth1 on A, was now eth0 on B, and this did not work. This was only a kind of experiment. There is a problem with the partition table on machine A, and I thought it would be useful to have a backup machine with exactly the same setup.

Best practice?? I don't think so ... You need to choose between two
different virtualization products. And the principal point here is: your
budget and your SLA.
- How many vms supports each one??

- when you use KVM using more KVM VMs then X is not advisable since ...
- How many nodes can install inside a cluster??
- How many ram can I assign to a vm??
As many as appliaction need.
It depends. There isn't a magic formula to accomplish this.
- Hard and soft limits on both platforms???
- What type of storage is supported on both platforms???
In general when you have many OS-es (CentOS) you face following problems:
- how to keep up with package updates ?
Like in physical world...
- how about security - is it easier to manage many CentOS-es or just one with
many KVMs ?
It's the same. But security is another beast You can't control your
virtual infrastructure like you do in physical world ... Virtual
infrastructures are more vulnerable ...
- how to keep up with application maintenance (mysql, postgresql, apache,
dns, etc) ?
Same as you do in physical world.
Which approach would be better/easier ?
Between what?? vmware and kvm?? In your case, KVM is the best option if
all vms are centos.

That's normal. Anaconda does a bit of magic during the install in detecting the hardware and setting things up for it. Within limits, running kudzu will adjust some of them and sometimes it will kick off automatically when hardware differences are detected. Also the ethernet connection, which had been eth1 on A, was now eth0 on B, and this did not work. That will always happen even what you think is identical hardware, but if you are at the machine you can fix it manually. If kudzu runs it will set up the interfaces for dhcp and discard your old settings. This was only a kind of experiment. There is a problem with the partition table on machine A, and I thought it would be useful to have a backup machine with exactly the same setup. Is this a hopeless enterprise, or can it be done easily? Neither. It isn't easy and I think that is a real deficiency in Linux distributions because most people probably think they can have their backups working quickly if their machine dies. But, it also isn't hopeless - you just have to know as much about hardware and drivers as anaconda does. Or you can cheat and do an install on the new machine first and keep at least the initrd or all of /boot and perhaps modprobe.conf and a few other things. In general it is better to plan for a new install and have backups that don't overwrite the system part but there is not a clean separation between system files and you own, so plan to spend a lot of time sorting out things from your backups of /etc and /var and merging them. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I do dd imaging quite frequently, and as long as everything is LBA48 capable and setup, I don't have problems copying partitions or whole drives between multiple drives of different sizes and manufacturers; even in instances between different interface technologies. This gets better once you're on an OS rev that treats ATA drives as SCSI, and CHS is no longer in play at all, which is the case in EL6 and Fedora revs around EL6. (At least I think that's correct; but it has been an awfully long time since I've done a CentOS 4 or 5 install on an ATA/IDE system, as all of my server systems are either SCSI or FibreChannel, physical or virtual). Having said that, I quarterly rotate two identical drives in this laptop; each quarter, I clone the currently operating drive to the secondary and to a dated whole-disk image file, and then swap the drives, putting the previous primary back into the fire safe for storage. This both wear-levels and tests the backups drives. I use a three-tiered approach to backups of my own laptop: 1.) Quarterly swapping drive clones as described above, using dd (which is faster than the slightly more friendly ddrescue, unless a bad sector is found) booted from rescue or live media of the OS that's installed (this provides a fast bare-metal base recovery that I can then update and restore from the rolling rsync in item 3); 2.) Three quarters of kept images along with the partition mapping (I use GPT, and thus use gdisk for this, which works better in my particular case than parted does (parted puts an inappropriate partition type on one of my partitions when recreating the partition map)) on multiple disks; 3.) Frequent rsyncs of /home and /etc to multiple drives, in rotation. This does mean an SELinux relabel might be required on a restore, but that's ok. For servers I do the same, but with annual images and more rigorous scheduling of tarballs of important files, along with rolling rsyncs (I've looked at rsnapshot, and backing up the backup can be somewhat interesting in that case). Dump/restore has its advantages, too, however. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The drives must be identical manufacturer and model, down to the firmware revision. dd is not a backup tool in the general sense. I do dd imaging quite frequently, and as long as everything is LBA48 capable and setup, I don't have problems copying partitions or whole drives between multiple drives of different sizes and manufacturers; even in instances between different interface technologies. This gets better once you're on an OS rev that treats ATA drives as SCSI, and CHS is no longer in play at all, which is the case in EL6 and Fedora revs around EL6. (At least I think that's correct; but it has been an awfully long time since I've done a CentOS 4 or 5 install on an ATA/IDE system, as all of my server systems are either SCSI or FibreChannel, physical or virtual). Clonezilla-live is a handy, faster way to do this. It boots from cd/usb into a menu and generally uses partclone to do the work so on most filesystems it only copies the blocks that are actually used. It also has a mode to resize the partitions on the new disk but it isn't all that useful because you can't control them individually. Having said that, I quarterly rotate two identical drives in this laptop; each quarter, I clone the currently operating drive to the secondary and to a dated whole-disk image file, and then swap the drives, putting the previous primary back into the fire safe for storage. This both wear-levels and tests the backups drives. Besides disk-disk, clonezilla can save/restore compressed image copies over the network to space mounted via nfs/samba/sshfs so if you are making the copy as a backup or the source for future clones you can drop it on some other filesystem instead of needing a matching disk. I use a three-tiered approach to backups of my own laptop: 1.) Quarterly swapping drive clones as described above, using dd (which is faster than the slightly more friendly ddrescue, unless a bad sector is found) booted from rescue or live media of the OS that's installed (this provides a fast bare-metal base recovery that I can then update and restore from the rolling rsync in item 3); 2.) Three quarters of kept images along with the partition mapping (I use GPT, and thus use gdisk for this, which works better in my particular case than parted does (parted puts an inappropriate partition type on one of my partitions when recreating the partition map)) on multiple disks; 3.) Frequent rsyncs of /home and /etc to multiple drives, in rotation. This does mean an SELinux relabel might be required on a restore, but that's ok. For servers I do the same, but with annual images and more rigorous scheduling of tarballs of important files, along with rolling rsyncs (I've looked at rsnapshot, and backing up the backup can be somewhat interesting in that case). Dump/restore has its advantages, too, however. I always recommend backuppc for scheduled backups. It's pretty much configure and forget and it compresses and pools all identical content so you can keep much more history online than you would expect. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It's been around for years, is lightweight (in terms of minimal dependencies), and is absolutely solid. I've had good success in moving dump images to new hardware as long as your hardware is similar (ie: not mixing Intel/AMD), and those aren't problems with dump/restore but rather the OS that you're copying. For a straight clone, the recovery steps would generally be: - partition your new drive and create the new filesystems - use restore to extract your data - reinitialize your boot blocks (MBR or whatever) - boot the system I don't know of any UNIX that doesn't ship with it (although there are variations among the UNIX flavours). The assumption is that your're backing up on a per-filesystem basis, as file exclusion for dump is rudimentary. With file-based copy schemes like tar, rsync, cpio, etc, you have better control for file exclusions, but you need to make sure you're paying attention to how you handle symlinks, hard links and other unusual file setups.

Tip 1:
Your files and directories can have different permissions. Rather than
your original setup, try:
chown -R apache:contenteditors /var/www/html
find /var/www/html -type f -exec chmod 0464 {} +
find /var/www/html -type d -exec chmod 2575 {} +

find /var/www/html -type f -exec setfacl -m g:contenteditors:rw {} +
find /var/www/html -type d -exec setfacl -m g:contenteditors:rwx {} +
Tip 2:
Don't install drupal in /var/www/html. Generally, /var/www/html should
be used only for static content. Web applications should be installed
outside the document root to prevent a misconfiguration from allowing
remote clients from downloading files that might contain configurations,
passwords, or other sensitive information. See the rpm packaged drupal
for an example of how this is done.
Tip 3:
If your application says that it needs write access to
sites/default/files, then add write access only for that directory.

I have been working wit the Relax and Recover project for the past few months together with a colleague and it now covers a lot of situations: - HWRAID (SmartArray), SWRAID, DRBD, partitions, encrypted partitions, LVM - It supports bootable tapes (OBDR), ISO images and USB media - It supports backup software for restoring (like Bacula, TSM, rsync and others) - And it can also take care of backups (using rsync, tar) using different solutions (NFS, USB, Samba, ...) - It's modular, so with little effort you can implement your own workflow or use-case However I would stress to test a complete disaster recover scenario for your systems (different technologies) in order to understand if everything is supported. You don't want to realize a problem in disaster-mode :) But for the use-cases we have, the current trunk is very usable and flexible to support restoring on different hardware.

[CentOS] centos friends?
Hello All, I want to ask about CentOS and money. Please do not start some kind of shitstorm over this, it isn't productive. I have just been looking at archive.org to see when the paypal option went missing from the donate menu at centos.org. I can't pin it down, but it was there on October 16, 2010 and isn't now, so that's the information I have on that point. There was a great deal of argy-bargy on this list when the 5.6 update was slow arriving. I don't want to go there, I was happy to see it when it arrived, as I always am when there's an update. The impression I got was that the maintainers and packagers were working as hard as they could and were tetchy about being nagged, being unable to do more. Fair enough, but we need not adopt the status quo entirely. The donate menu on the web site has this to say, (and more) ... The CentOS team would like to remind you that the primary means of substaining the development of CentOS is via contributions by CentOS users. CentOS is now, and will continue to be totally free; however, it takes money and resources to make CentOS available. If you are able, please consider donating to the CentOS Project. Donations of promo material, public mirrors and dedicated servers are all vital to our contined operations. Monetary CentOS is currently reviewing our cash donation program. In the mean time we are not accepting any financial donations. We do appreciate though, if you want to - for example - help out with promo material. See our Wiki page on donations for more up to date information.

We rely on contributions and donations from CentOS users as well, for: * Logistics related to promotion and infrastructure * Specific hardware needs * Bandwidth and connectivity * Promotion material at conferences and exhibitions * Organizing CentOS-related events I don't see anything there about money except in the first line and I'm really curious why. Internally it is clear that if the team hasn't put in place some cash donation basis probably the capacity isn't there. But the current team need not go into areas where they have no time or (perhaps) expertise. There are lots of capable money folks in the free software world who can and do accept donations and deal with administrative infrastructure and channel support to projects. So the name apache-friends is suggestive. Without necessarily using that model I wonder why there isn't a CentOS Friends group or fund to which I and others can donate. I can't help but believe that if there were, say, a couple of paid staff with CentOS as the day job, things would not be so burdensome to the devs we have now and maybe we could build on that.

On 05/05/2011 09:09 AM, Pasi Kärkkäinen wrote: It sounds like your hardware does not have HVM support, which means you can only run PV VMs. Thanks for the reply. You are correct. I have two P4 32-bit machines that I just picked up and wanted to use them for testing until I can afford to upgrade to the 12-core MB/Processors that I bought these 2u chassis into which I plan to install. I have never used xen, and it just seems kind of odd that you cannot simply install from the hard drive, like on virtualbox. Anyhow, I could only figure that was the outlying factor. I could not locate that aspect of the virt-manager docs, so I will check again. Anyhow, now I am fighting with SL-Linux's installation media for i386, having the ability to be seen, and booted, but inside their own boot menue, it forces you to re-verify that you have install media. (Even though it is running from the media in the first place. Then Xen magically can't see the iso that SL linux is running from.) Are there any good (I guess dated, now that everything is mulit-core) docs on how to work with paravirtualization, since I have to deal with this weird network install setup? It seems that I can put in the explicit path to the local-disk-installed ISO image, but the second it boots, nothing can be found, and it asks me to put in a url, etc... I know this sounds incoherent, but I am burnt out from exams. Installation for PV (paravirtualized) VMs is only supported by using netinstall in virt-manager. HVM (fully virtualized) VMs can be installed from ISO image. Thanks for the input, and would appreciate any further direction on reading further on real-world installs, not the docs where they assume you have a quad 12-core processor super server so everything thing just works in virtualmode... ) I guess this is more for virt-manager, but I think you will understand what I mean if you check the doc site for virt manager. They don't even mention that there is a limitation such as what you have described, except to say there is a limitation. Sorry for the ramble.

But if backuppc has a client, or a configuration, it's very easy to make ReaR aware of it. And then to only configuration you would need to do is: BACKUP=BACKUPPC Backuppc usually doesn't need anything on the client side. The server can run rsync or tar over ssh or use smb or talk to rsync in daemon mode. It's basically a couple of perl programs to do the scheduling and provide a web interface wrapped around standard tools. But, if you haven't used it, the thing it does better than any of the similar programs is that it compresses the files and pools all duplicate content with hardlinks so you can keep a much longer history of more hosts online than you would expect. It has an rsync-in-perl implementation to deal with local compressed files while chatting with a stock remote version. And it has a nice web interface to browse/restore files. Or you can use a command line tool to generate a tar image. and it would automatically create a bootable image with your system's layout and the backuppc software/configuration, and even the necessary commands to automatically recover your system when doing: I don't really want a separate copy of an 'image' built. I want something to do the grunge work of partitioning and creating the necessary filesystems, then pull the tar image from the backuppc server with an appropriate ssh command. rear recover on the rescue prompt. That's how it is done with Bacula, TSM, and others. You could probably do something very similar by generating the tar image(s) ahead of time from the backuppc server and storing them in your recovery setup. And that would be useful for archiving, offsite, or cloning purposes, but the main thing I want is the ability to boot something that can mindlessly reconstruct a machine from last night's backuppc run straight out of that compressed/pooled storage. I already trust backuppc on the 'save a copy' side. I'd rather not replace that part. Does backuppc take care of restoring HWRAID, SWRAID, DRBD, LVM, paritions, filesystems ? If so, then ReaR may not be for you, because ReaR takes care of those items. No, backuppc just saves files and can give you what looks like a tar image (or put them back if the target is working well enough to accept them). That's why I'm interested in something else to do the work up to where you would restore a tar backup. It's not extremely difficult to do by hand from a livecd boot, but automation is always better. Backuppc does handle the more common case of someone wanting a few files back that they accidentally erased very nicely and I don't want to do a whole different backup to cover rebuilding the machine. If you need more help, feel free to join the ReaR mailinglist on sourceforge and ask your questions :) Would a backuppc adapter be feasible? Definitely, join the list and we can help you implement it. OK, I'm interested... It's probably just a matter of generating whatever description of the underlying storage it needs and plugging in an ssh command to get the data at the right point. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
