There's only what you know, how you can adapt what you know and how well you can make it work for you and how much time you are willing to give to learning something new. If I may expound a tad, and I will endeavor to keep this brief, it goes one step farther than this. It becomes a balance of how much time and effort will it take to adapt what you know to your task? against how steep is the learning curve for something you aren't proficient in, but is already known to do your desired task? And sometimes, if not most of the time, it's a three-way balance with what is the cost, monetary or otherwise, to get someone else to do it? As an example, I have four relatively nice SGI Altix IA64 systems here. I would prefer to run CentOS on them, since I can't afford RHEL for them, nor is RHEL 6 available for them. I have the knowledge to rebuild EL6 on the boxes, but I honestly don't have the time to work through all the details, even though the geek packager in me desperately wants to try. The latest Debian Stable works quite well on the boxen, but my knowledge of Debian is somewhat limited. So, I have a three-way balance between: 1.) Pay the cost of RHEL, with the knowledge that RHEL 5 is the last for IA64; 2.) Maintain my own private or semiprivate rebuild for IA64 of EL 6; 3.) Install Debian and get the boxen doing something (and potentially generating revenue), and climb yet another learning curve. I chose 3 at the moment.

Re: [CentOS] Redhat vs centos vs ubuntu
Just to throw out the background on the thread... It was started questioning whether redhat is going to actively try and make it harder over time to clone it, thus making any derivatives of it untenable. I tried ubuntu and that is what this sub thread is about. I tried ubuntu from the standpoint of a non-developer, non-it-worker, hobbyist web site owner putting together a stand alone webserver. Ubuntu vs centos in this regard goes fully to centos. Having to get a degree in grub, iptable scripts, etc just to do a out of the box install of a virtual host is rather much in that regard. Centos had a much easier and somewhat more intuitive installer and installed a firewall that limited input to a bridged device and port 22. Ubuntu opened the virtual host to the entire lan, all ports, and added forwarding to non existent virtual bridge that had not been built yet. Ubu had forced me during the install to download packages and get on the net. Centos did not. From what I now understand of debian derived ubuntu is they are quite an excellent desktop system and are working on an interesting cloud infrastructure. I understand now that ubuntu command line stuff (non desktop) is for someone with much more knowledge of linux and all its programs than a person using centos would need to know. In that regard, not coming from a bank of servers and knowledgeable university background, ubuntu is a massive learning curve far beyond the pre-set-up nature of centos. I did want the ability to get newer programs in regards to web stuff like php. I may try to install some ubu as web servers, but not as the virtual host. It seems to require too much time and knowledge to properly secure it. With centos I can lock the virtual host down and access solely through the ipmi interface ensuring that as the only fail point. Right out of the box. Easily. I like the security and ease of it. As a virtual host, I found ubu install tedious, slow, and demanding way too much knowledge and skill to just simply start adding guests and go. Ubu virtual host is definitely requires much more configuration skills than centos. Something I do not feeling like having to learn when centos comes with it set to go. If you are from a university background or have worked with many types of linux for a long time, then maybe it is simple for you to take a few minutes out and configure the scripts for network, iptables, secure the box, check all the pre-installed stuff. But for me it would take much longer and I would never know what I missed. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Le 11/11/2011 10:39, Bob Hoffman a écrit : Ubuntu opened the virtual host to the entire lan, all ports, and added forwarding to non existent virtual bridge that had not been built yet. This is simply false for Ubuntu Server. After first install, there is simply no single port opened, even 22, you need to install openssh for that. So there is no need for a firewall with the basic install. It is this philosophy that is not unsderstood by RHEL.CentOS users. You don't need a firewall when there are no ports opened. The first release was even delayed because it remained one open port ! Meanwhile, you can access the Internet (it does not open ports on the external), and update your machine. I am using Ubuntu Server for VMs, and I like this behavior. It is very light, and a fast installation. Then I install and open only the required services and ports, and control the ports that can reached from Internet with a site firewall.

Unless I missed something, your last advice posted here was to stick to 5.x. What's the official support position on that today? There is no official position. I personally use 5.x for almost everything because there are still more than 2.5 years of support for 5.x, 5.x is very stable, and 6.x is still very new. However, just from a security perspective either 5.x or 6.x is fine now if you are using CR. There are 2182 6.1 or newer RPMS in the x86_64 CR repo right now. I certainly use 6.x on my workstation machines ... admittedly they are not normally directly Internet facing.

If you don't like CentOS, fine, this list, however, isn't the venue to rattle on about it. This thread and others like it are not about people not 'liking' CentOS all of a sudden and everyone know that. It is about what the people who expected a reasonably current CentOS to be available may be forced to use instead. If you are unhappy with CentOS then you need to think that perhaps you should be using something else. And if you _are_ using something else why bother taking up my time and that of the thousands of other list members complaining about CentOS or expressing your various displeasures here? We are pretty much all in the same boat here. If someone can authoritatively say that CentOS will never be more than a few weeks (even months, whatever...) behind upstream, then such discussion will end of its own accord. Otherwise everyone needs a plan B. What is older than that now if you look at 6.x CR? The only thing lagging right now is the building of new install media. But if you install 6.0 and use CR, you are in good shape. There are even updates in there that are newer than 6.1 (it also contains the updates TO 6.1). I can never say how long it will take to build something that we have not built yet ... if we have to redesign a system from scratch, it will take time. You are correct, if CentOS does not work for you then move on. Move on to a new OS and move on to a new list. So I ask you, and all the others, to _please_ consider that the _vast_ majority of active readers of this list don't care one way or another about opinions of CentOS vs Ubuntu or hearing, yet again, about your displeasure with whatever is irritating you today about CentOS. Sorry, but I don't believe that there is any such vast majority that isn't concerned about the situation. This list is for the community to use to get and provide support for CentOS ... not for constant bellyaching and non stop whining.

One day with ubuntu server and you will look at centos install and setup as a god! I'm assuming your refering to ubuntu 10.04 LTS. Like every distribution it's got it's quirks. I routinely use both CentOS/Redhat and Ubuntu for different purposes. Both distributions have things that I like and things that I don't like so much. If you've been running Ubuntu or other debian based distribution, you could install CentOS/Redhat and spend quite a bit of time becoming familiar with Redhat. My responses in this message are NOT meant to be an attack on redhat CentOS, but simply to share some of my experiences with Ubuntu. Where do I begin? 1- you download the iso, burn a cd. But guess what? It is only a small boot setup (about 600mb). The install actually sets up your eth port and then SLOWLY downloads a base set of packages. Then when you are done with your drive set up, you get to pick a package. Then it downloads and installs, asking you a few questions as it does. Then it upgrades itself. About 40 minutes due to the downloads for me... The package management tools in Ubuntu/Debian are small and fast. I've come to like them, though I fought with them at first. I like their handling of dependencies. The package repositories for Ubuntu/Debian are huge. I've rarely had to go outside of the Ubuntu repositories looking for software that I needed to run. I've spent much more time compiling software and messing with outside repositories for CentOS. My understanding is that Linux in general is moving towards a common package management and package format that will be shared by most linux distributions. 2- uses a really lame 1980 DOS version of a text installer. It does not and will not use a basic vid driver install which means your setting up of lvms and such during the install is really fun. I believe the standard desktop uses Ubuntu's own installer. The Ubuntu server and the 'alternative' distribution use the debian installer. I fought with it at first, but it is much more flexible than the redhat installer. You can build arbitrary LVM/raid configurations with it and you can also go into the shell from the installer and customize things that you can't with the redhat installer. 3- I don't know about having a server being forced to connect to the internet before you can even begin to secure it up. But the only way to really install it is to do that. Wait til you see the insecure firewall setup if gave me too.. I've not experienced any distribution to provide a great default firewall setup. What I do notice about Ubuntu server is there are very few services running in the default install, so if you probe a newly installed machine, it's not very vulnerable. I usually run new installs behind my Internet firewall anyway. I like doing a basic install and then adding the services that I want to enable, rather then a server install that comes up with dozens of services that you may not need and you have to turn them all off to secure the machine. 4- I picked the virtual host package, as the machine will hold guest OS's (presumably ubuntu). I do like CentOS/Redhat 6 better as a virtualization server. Thing to realize here is that Redhat is leading the development effort for KVM, libvirt etc, so Ubuntu's code lags behind redhat. For the current stable Ubuntu 10.04 LTS release Ubuntu lags behind redhat 6 and since 10.04 LTS is a stable release it doesn't just get arbitrary updates unless they are security fixes. One thing I like about Ubuntu/debian is the /etc/network/interfaces file over /etc/sysconfig/network-scripts /etc/sysconfig/network. 5- booted up fine. 6- uses upstart and init, mixed up a bit. Upstart, BY DESIGN AND ACCORDING TO DOCUMENTATION is new and still being built so they do not want to put any documentation out on it yet. This makes chkconfig and things like that useless. Hence, if you want to know what is running, set to run, etc, you need to dig in multiple folders and read the scripts. There is no other way. What a horror. Redhat 6 uses a similar hybrid mess between the old startup format and upstart. Like many things in Linux, finding good documentation is not always easy, but it can be found. It takes a bit of time to master upstart, but it does let you create dependancies in the startup process which is nicer than having to add sleep commands and doing other things to muck with daemons that have dependancy on other services. Upstart is going to be replaced in future Redhat releases. http://bazaar.launchpad.net/~upstart-documenters/upstart-cookbook/trunk/revision/30 http://bazaar.launchpad.net/%7Eupstart-documenters/upstart-cookbook/trunk/revision/30 I do find apparmor a whole lot easier to master than selinux. 7- The install, of the virtual host, added libvirt.

You have to build your own firewall file and add scripts to make it over ride the stock one via the eth you want to use it forwtf? 9- here is the firewall, for a virtual host, that should not have anything but port 22 open as far as the initial install should (at least in my opinion).Ubuntu starts with this (remember, ubuntu forces you to be online to install and this is how it protects your server) I was not blocked on a single port going from my desktop to my server via my router. ALL PORTS were accessible. This is out of the box. Shell 22 was open from all my computers. Not listed in the firewall as open.

From http://0pointer.de/blog/projects/systemd.html : A central part of a system that starts up and maintains services should be process babysitting: it should watch services. Restart them if they shut down. If they crash it should collect information about them, and keep it around for the administrator, and cross-link that information with what is available from crash dump systems such as abrt, and in logging systems like syslog or the audit system. Status All the features listed above are already implemented. Right now systemd can already be used as a drop-in replacement for Upstart and sysvinit (at least as long as there aren't too many native upstart services yet.

Of the PC things, SLS was probably the most fun to do, but that's primarily because that was so long ago and even Windows 95 was available on floppies and it was just so cool to run a *nix on the 386SX box the coolness factor has definitely worn off. So I'm in somewhat of a position to comment on what I want and don't want from an install, be it text or GUI. Regardless of ease of install, I very much want/desire/need something that once the initial no-internet-connection install is complete the box comes up with things pretty well locked down by default. CentOS/SL/upstream EL does this, by default, and that is good, updates or no updates. Updates are no more of a panacea than firewalls are. If you doubt the speed at which a non-locked-down system can be exploited, take a 1990s vintage copy of, say, RHL 6.2, go ahead and pre-download the last set of updates for that distribution, do the install on a public IP with no firewall appliance in front of you, and see if you can get the updates installed before you're pwned. This is the world we live in, especially with advanced persistent threats gaining internal network access; firewalling, even on the inside, is no longer optional for a server install. The firewall of course is but one layer in the security of the system; MAC helps immensely, as do proactive NAC/IDS/IPS setups.

As Mark Twain once said, I didn't have time to write a short letter, so I wrote a long one instead. And I type (and read) relatively quickly But on-topic, hopefully, I would say that there are more similarities between CentOS and Debian Stable than between Ubuntu LTS and CentOS, primarily due to the way security and version upgrades are handled in terms of process, but that's my opinion because my use cases are better served by the CentOS way of doing things, at least for now. And I would add Scientific Linux to the comparison mix partially due to the difference from CentOS in the way SL handles security-only updates even for older point releases. To see a very clear example of SL's way of doing it, please look at the timestamps of the packages in: ftp://ftp.scientificlinux.org/linux/scientific/50/x86_64/updates/security/ which is the security updates directory for SL 5.0.

I noticed upon a new datacenter install with new ips a large number of very strange traffic hits my firewall logs are full of it.

Ubu and centos, different animals. However, the ubu server is touted as an enterprise ready system with commercial support. I found the initial install lacking in that regards and the commercial support sales never answered my mails. I think ubu is all about the desktop and really getting into the cloud. But for a standalone webserver the initial setup is not ready for prime time. I think a company with some good techs can build a nice system that can then be passed along to their servers.

- Original Message - | This is a continuation of the thread about redhat vs centos and the | thought of moving from centos | due to redhats new business model. Forgive the length, but I had to | share. | | I went ahead and downloaded the 5 year supported version of ubuntu | server. | You think centos/redhat is a bit tough or not polished? | One day with ubuntu server and you will look at centos install and | setup | as a god! Let me start out by saying that I totally agree with you here. Ubiquity is a really crappy installer! I've fought with it for many years. However, like RHEL/CentOS you can use kickstart to install the machine. It's called kickseed in Ubuntu/Debian and maps a subset of the Kickstart features to the debian-installer equivalent. | Where do I begin? | | 1- you download the iso, burn a cd. But guess what? It is only a small | boot setup (about 600mb). | The install actually sets up your eth port and then SLOWLY downloads a | base set of packages. This, like the RHEL/CentOS installer can be changed if you are using kickstart. If you are are installing from CD it will install packages *that have not been updated* from the CD. However, the installer does check security.ubuntu.com and downloads updates during installation for those packages. This would be the equivalent to including the updates and CR repos during a kickstart. | Then when you are done with your drive set up, you get to pick a | package. | Then it downloads and installs, asking you a few questions as it does. | Then it upgrades itself. | About 40 minutes due to the downloads for me... See above statement. If you are kickstarting, it's no big deal. | 2- uses a really lame 1980 DOS version of a text installer. It does | not | and will not use a basic vid driver install | which means your setting up of lvms and such during the install is | really fun. Then you downloaded the alternative, netboot or server installer. The desktop installer is fully graphical, however, is lacking many features such as LVM and RAID support selections. This is *entirely* different than Anaconda which actually works the same whether using the text, VNC or standard graphical install. | 3- I don't know about having a server being forced to connect to the | internet before you can even begin to secure | it up. But the only way to really install it is to do that. Wait til | you | see the insecure firewall setup if gave me too.. And during installation of RHEL/CentOS how to do secure the box before installing? How about applying updates before putting it in production? Let's be fair here. | 4- I picked the virtual host package, as the machine will hold guest | OS's (presumably ubuntu). Would be covered by a kickstart and a virtual host package is the equivalent to the package group in RH speak | 5- booted up fine. | | 6- uses upstart and init, mixed up a bit. Upstart, BY DESIGN AND | ACCORDING TO DOCUMENTATION is new and | still being built so they do not want to put any documentation out on | it | yet. This makes chkconfig and things like | that useless. Hence, if you want to know what is running, set to run, | etc, you need to dig in multiple folders and | read the scripts. There is no other way. What a horror. You are arguing that something is misunderstood by you and thereby horrific. As a person who manages several UNIX UNIX-like operating systems, I would agree that it is horrific to have to understand the differences about how to enable / disable services on each platform. | 7- The install, of the virtual host, added libvirt. It did not however | install things like virt-install or any other virt software. | Infact, no guest installation tools were added, though things like | virsh | were installed. Sigh. That is correct, those packages are provided as extra tools. They are not needed for virtualization to work. | | 8- The firewall and network do not have the scripts folder. You have | to | build your own firewall file and add scripts | to make it over ride the stock one via the eth you want to use it | forwtf? Is it that you don't understand where they are or that it's just not possible? There's a difference. Yeah, on RH there is an /etc/sysconfig/network-scripts. On Debian/Ubuntu there is a /etc/network/interfaces file that controls all. What's wrong with that. Personally, I can think of lots of things, but it's my opinion. I'm trying to show that you are making assumptions about how this should be compared to how things are before learning the why things are the way they are. | 9- here is the firewall, for a virtual host, that should not have | anything but port 22 open as far as the initial install | should (at least in my opinion).Ubuntu starts with this | (remember, ubuntu forces you to be online to install and this is how | it | protects your server) | | I was not blocked on a single port going from my desktop to my server | via my router.

Or, to be explicit, let me invent an example: suppose that I have leased virtual hardware from some 3rd party, and have obtained a virtual machine with 6 vCPU's. I want to buy RHEL licences to install on that machine. AFAIK, RH counts licences in sockets. How many licences should I buy? Or, iow, how many sockets is equal to 6 vCPU's? Does RH have a formula for the number of sockets as a function of the number of vCPU's (and vice versa)? Best, :-) Marko Socket != vCPU. There is no need for a formula. The licensing is done based on the hosting hardware. That does not mean it has to be a RHEL hypervisor. When I got my quotes it was to put 4 guests on a 2-socket VMware ESXi server. That would be a single license for 2-socket w/ 4 guests. That wouldn't change no matter how many vCPUs I used. It's much easier to ensure license compliance on the hosting hardware than on something as dynamic as the vCPU count.

There is no need for a formula. The licensing is done based on the hosting hardware. What gives? Let me stress again: there is *no* *information* about the hosting hardware! It is in the cloud, on some mainframe or cluster of the cloud provider. That hardware is potentially subject to change over time and at provider's discretion, without me even knowing about it. There are no sockets for me to count anywhere, only vCPU's. Damn, that's why it' called s a *virtual* machine! RH licence model is based on the assumption that I own or otherwise have physical access to the hardware on which I am to install RHEL, and can consequently count the physical sockets of that hardware. This assumption is *false* for the situation discussed above. The hardware is *not* available for counting sockets, and in addition is a moving target (subject to changes). If RH does not have that case covered at all, I can understand, and that's OK. It's probably best to contact a RH representative and discuss what to do on a case-by-case basis, which is also OK. What is *not* OK is people on this list authoritatively telling me that everything is clear and that I have difficulty understanding what they are saying. When in fact it is the other way around.

I can't understand the licensing model of RHEL because a VM doesn't have a socket.

Well, what I don't understand is how many vCPU's are equal to one socket. Or, to be explicit, let me invent an example: suppose that I have leased virtual hardware from some 3rd party, and have obtained a virtual machine with 6 vCPU's. I want to buy RHEL licences to install on that machine. AFAIK, RH counts licences in sockets. How many licences should I buy? Or, iow, how many sockets is equal to 6 vCPU's? Does RH have a formula for the number of sockets as a function of the number of vCPU's (and vice versa)?

Best, :-) Marko ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos Socket != vCPU. There is no need for a formula. The licensing is done based on the hosting hardware. That does not mean it has to be a RHEL hypervisor. When I got my quotes it was to put 4 guests on a 2-socket VMware ESXi server. That would be a single license for 2-socket w/ 4 guests. That wouldn't change no matter how many vCPUs I used. It's much easier to ensure license compliance on the hosting hardware than on something as dynamic as the vCPU count. I'd recommend contacting Red Hat to get a definitive answer as I am basing what I know on my talks with my campus' Red Hat rep several months ago. - Trey ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
