Si con el CD te ha resultado, baja la ISO en CD y con ella has la instalación, claro que tendrás que hacer la instalación básica y después desde internet instalar lo que te falta, yo recomiendo esta opción ya que instalo un sistema base, y luego desde repositorio instalo lo que necesito, me queda muy limpia la instalación y es perfecta para trabajar en servidores :P Acá esta la lista de mirror donde puedes encontrar las isos: http://mirror.centos.org/centos/5/isos/ Saludos.- El 24 de noviembre de 2010 17:14, Eduardo Fuentes eduardofu...@gmail.comescribió: Hola, nuevamente Hice lo que indicaron, al parecer es el DVD, no puedo instalar desde ese DVD sea configurando las particiones manualmente o instalando en las particiones que por defecto pone el Centos.

[CentOS] CentOS vs. RHEL vs. Oracle Linux ?
Hi, I've been contacted by a local training center specialized in Oracle databases, to train a group of four administrators to use Linux. They're supposed to use Oracle Linux (more exactly OL5), which I understand is some specialized version of Red Hat Enterprise Linux. I'm reasonably proficient with CentOS. I've been using it exclusively on desktops and servers since 2007 (version 4.3 if I remember correctly), after a few years on Slackware and Debian. I've setup CentOS-based networks in small town halls, public libraries and schools, my dedicated webserver is running the latest CentOS, and I've published a book about basic Linux concepts entirely based on CentOS 5.3. On the other hand, I've never got to work on the real thing, so to speak. The only time I put my hands on a Red Hat Enterprise Linux server was to retrieve the root password for a distracted client (add init=/bin/bash to the kernel line in GRUB, mount -o remount,rw /, passwd :oD). And I never came near a machine running Oracle Linux. What differences can I expect between a server running Oracle Linux and my average server running CentOS ? As far as I can guess, their unbreakable Linux kernel will still be some package called 'kernel' (with the according 'kernel-devel' and 'kernel-headers' packages). Probably Yum will be used as a dependency resolver (will it?), only with different repositories. And for the rest, I except it to work the same, in that I can still use chkconfig, ntsysv, rpm, etc. (what about system-config-securitylevel-tui or similar tools?) In short, what differences/similarities can I expect? Is there some document stating these?

Hi, I've been contacted by a local training center specialized in Oracle databases, to train a group of four administrators to use Linux. They're supposed to use Oracle Linux (more exactly OL5), which I understand is some specialized version of Red Hat Enterprise Linux. I think they offer you a choice of kernels. Their own kernel has performance enhancements. It's also supposed to be cheaper in maintenance than RHEL. But AFAIK, it's a re-engineering of RHEL in the same way CentOS is. Just with commercial support (and geared towards running Oracle stuff). I just looked and at the most basic level (patches only) it costs 94/year/system.

[CentOS] DisplayPort output with intel graphics driver?
Hi. We've installed CentOS 5.5 on a mini PC with an onboard Intel graphics chip, which has both VGA and DisplayPort output. This works reasonably well, except that I'd like to connect the monitor to the DisplayPort, and I only seem to get a signal on the VGA connector. This is the case even if I boot with the DisplayPort (only) connected, in which case console output during boot goes to the DisplayPort, but the graphical output does not. On the other hand, . DisplayPort display did work when booting from a live Ubuntu CD. Is there anything I can do to get the correct display setup? Note that the driver used is intel, not i810.

Thanks. I believe I missed that file because I searched for operating system independent components (because firmware doesn't use the OS, right?), but apparently I should have chosen some Linux variant instead. I should perhaps mention that I found a solution, sort of: It seems like the problem is that the system simply won't boot from a single hard disk set up as just that - a single, separate drive. I suspect this has something to do with the disk/RAID controller firmware, but updating it did not help. If, on the other hand, I define (from within the controller setup screen) a RAID containing only one drive, everything works just fine... Try nodmraid on the kernel line in grub - I needed this after one of the upgrades in the 5.x series. The problem is that the system never gets to the grub stage, i.e. it fails to boot from hard drive at the BIOS level, so as to speak. Of course, this probably means the problem isn't related to CentOS at all, but I didn't quite realise that when I posted the original question... - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.

Re: [CentOS] Router for SOHO network - hardware considerations
Niki Kovacs ha scritto: Hi, Last week I finished installing a small network in a private school : one server (an old IBM X225), seventeen desktops (Fujitsu Siemens PIV 2.4 GHZ, 512 MB RAM, 40 GB HD), all running CentOS 5.5. One extra machine is acting as a router, in that it is installed between the DSL modem and the network, with two Ethernet cards, and it's taking care of DHCP, DNS, NTP and also acts like a proxy (with Squid). It seems quite big and noisy and electricity-consuming to me, so I wonder if there is any small device that could possibly do the job as good, but which would me more adapted : small, solid and cheap (if possible). I imagine some tiny box just with a CPU and a small harddisk, a little RAM and two network interfaces (one out, one in), where I could install a very stripped-down CentOS, and then just forget about it. So far, I've googled a bit, and I've found two things: 1) Pyramid Soekris boards, where I can put something like Pyramid Linux on it. And 2) The Linksys WRT54GL, for which there are Linux firmwares like OpenWRT and DD-WRT. Is there anything you could especially recommend for this job? (I'm not afraid of getting my hands dirty, BTW :oD) Cheers, Niki ___ Hi Niki, I would like to suggest the Tp-Link TL-WR1043ND; it could be a little more expensive than the Linksys, but it has a more powerful cpu, more ram and an usb port (and more or less same power consumption) for around 50 Euros. I'm using it with the original firmware, and I tested OpenWRT on it; next I will try endian, but I have to say that I'm very satisfied with it and I would recomend it: the system is fast and responsive, and the usb port adds really a lot of flexibility (eg. file sharing, usb dongle backup, squid with cache and so on...).

Look through some of the other scripts to see how they work. Sorry for the stupid question here, but does the /etc/initd./scriptname file know about these symlinks because of a particular comment in there? Copied from the man file for chkconfig: RUNLEVEL FILES Each service which should be manageable by chkconfig needs two or more commented lines added to its init.d script. The first line tells chkconfig what runlevels the service should be started in by default, as well as the start and stop priority levels. If the service should not, by default, be started in any runlevels, a - should be used in place of the runlevels list. The sec- ond line contains a description for the service, and may be extended across multiple lines with backslash continuation. For example, random.init has these three lines: # chkconfig: 2345 20 80 # description: Saves and restores system entropy pool for \ # higher quality random number generation. This says that the random script should be started in levels 2, 3, 4, and 5, that its start priority should be 20, and that its stop priority should be 80. You should be able to figure out what the description says; the \ causes the line to be continued. The extra space in front of the line is ignored. Basically, create your file by taking one of the files as a sample and place it in /etc/init.d. For example, I've copied /etc/init.d/vncserver to /etc/init.d/sample and ran [r...@hakan init.d]# chkconfig --add sample [r...@hakan init.d]# chkconfig --list|grep sample sample 0:off 1:off 2:off 3:off 4:off 5:off 6:off Now my sample is there but won't run at all but it's all there. [r...@hakan init.d]# chkconfig sample on [r...@hakan init.d]# chkconfig --list|grep sample sample 0:off 1:off 2:on3:on4:on5:on6:off Now it's on for all of the levels in the comment included in the file. Nevertheless, I could have overriden that with the ckconfig --level levels name on command options to run on other levels. [r...@hakan etc]# find rc* -iname *sample*|sort rc.d/init.d/sample rc.d/rc0.d/K35sample rc.d/rc1.d/K35sample rc.d/rc2.d/S91sample rc.d/rc3.d/S91sample rc.d/rc4.d/S91sample rc.d/rc5.d/S91sample rc.d/rc6.d/K35sample and the file comment looks like below which matches the above, startup priority is 91, kill priority is 35. It will run on all normal levels since it's not defined, excluding 1 (single user), 0 (shutdown) and 6 (reboot). # chkconfig: - 91 35 I better remove this sample from my startup :) -- Hakan (m1fcj) - http://www.hititgunesi.org ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Unfortunately, contrary to CentOS, this way of doing things doesn't get me Yum, and a manual install of Yum apparently requires some packages that are not on the first CD. So I'll simply wait for the other ISOs to download and go for something less minimal. I'm especially curious to know about the default Yum repos config : where does Oracle Linux have its repos and its updates ? Do I have to subscribe to something to get them or are they free ?

What we need is a What would a good sysadmin think? list where one of the criteria for being a good sysadmin would obviously be that you know something about Centos but the rest of the scope covers applications, conversions, product comparisons, legal issues, etc. The kind of stuff most of us do every day...

[CentOS] New list ?
Hi, Taking this to a new thread. Thoughts on getting a new list started up ? Should it be centos-sysadmin or centos-infra ? Are we going to then restrict it to admin/infra related chatter ? in which case, does the eyeball density on this list reduce for that sort of content ?

Re: [CentOS] CentOS vs. RHEL vs. Oracle Linux ?
I'm especially curious to know about the default Yum repos config : where does Oracle Linux have its repos and its updates ? Do I have to subscribe to something to get them or are they free ? Well, I guess I'll have to wait for my download to finish to get the answer. http://public-yum.oracle.com/ The yum repo is public but just contains the releases, no intermediate update packages. Those require an account on the ULN. See too http://www.oracle.com/us/technologies/027617.pdf The ULN is used by up2date, not yum. https://linux.oracle.com/uln_faq.html Cheers, Niki Alexander ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Generally speaking it's best to stick with rpm installs on a Centos system but if something consists of, for example, one single executable file, then you can just copy that anywhere that's convenient and run it from there. (Put it in /usr/local/bin if you want multiple users to have access to it, put it into ~/bin if you just want to use it yourself. That way it's on your default path.) 2/ Can I use fedora12 fping rpm to install on it? Some Fedora srpms can be recompiled for Centos. Sometimes it's a simple matter of rpmbuild --rebuild whatever.srpm, sometimes you have to edit the .spec file to make it work. And sometimes it doesn't work at all, depending on other factors like dependencies. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Whereas, if there is a centos-offtopic list or similar, which is very likely a high proportion of centos readers, you don't have any of these concerns (well, unless you go completely nuts like how do I find an SM club in Sochi?).

One potential proposal: centos-admin: tech topics that are not directly related to CentOS (Niki's Oracle Linux question would fit here) centos-offtopic: any other random runaway threads or non-tech topics We on the centos list need to be disciplined to move threads to the appropriate list when they get offtopic for centos (this means not relying on KB to intervene, but suggesting a move ourselves if we see it before someone else does) if we do go ahead with new lists that are not directly on-topic. --keith -- kkel...@wombat.san-francisco.ca.us pgpoHGWTT7z7l.pgp Description: PGP signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

And sometimes it doesn't work at all, depending on other factors like dependencies. It's not as easy as one might hope: There are new guidelins for writing Fedora RPM's, such as the use of '%global' instead of '%define', that can be very confusing. Also, the SRPM's from RHEL 6 and from Fedora 14 often have a 'docs' package that is compiled with the BuildArch: noarch option, which breaks the living tar out of compiling it unde CentOS 5.x or RHEL 5.x due to scattered debugifo debris which is not correctly bundled. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I've never been able to get IPSec and OpenVPN working together on a Linux box. Perhaps it's brain-fade on my part, but I have spent quite a bit of time trying. I have read that the original arguments about kindergarten cryptography from Microsoft in PPTP are not as valid as they once were, and we're not running it from Windows clients in any case, they're all using OpenVPN clients. The only place I'm currently running PPTP is from my iPad with iSSH to connect to our network. Any other connections I might need to make from the iPad are done with another ssh connections that originates from our LAN, not direct from the iPad. Other connections via the PPTP VPN are encrypted IMAP/SMTP connections to servers on the private side of our network.

You might test the program on a 64 bit OS. The 64 bit version of CentOS should be able to run many 32 bit programs. It would depend on dependencies in the program whether it would have issues or not. In fact, other changes since 3.9 may be more of an issue than the 64 bitness of the OS. It is possible to limit the amount of RAM that the OS will recognize by passing options to the kernel in grub. You also may be able to run a 32 bit version of the OS in virtualization under a 64 bit OS, leaving the rest of the RAM available for the main system. 2 computers in 1. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Unless you can't use virtualisation, you can run any 32 bit app on 64 bit platform provided that you have the 32 bit dependencies installed. The other way around is not possible. if you are compiling it from source, 32 bit and 64 bit libraries install in separate directories and thus you can point to the correct path in any configure script. I regularly compile Apache PHP for 32 bit on CentOS, thanks to 32 bit binary modules only available on that platform. -- Hakan (m1fcj) - http://www.hititgunesi.org ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You can run 32-bit applications with a 64-bit kernel. CentOS / RHEL installs the 32-bit shared libraries along with the 64-bit libraries. You can also install xen (or kvm) and run 32-bit slave (virtual) processes, with reasonable amounts of memory. If I take some RAM out of server (for example take out 32 GB RAM and left 32 GB RAM on server), will problem fix?

If I take some RAM out of server (for example take out 32 GB RAM and left 32 GB RAM on server), will problem fix? 16GB was the maximum recommended for PAE all along. PAE was a crutch to get above the inherent x86 32bit architectural limitation of 4GB. 32GB would likely work, and just use half the kernel address space, instead of most all of it. Have you tested this 32bit application on x86_64 ? you may simply need to install the correct 32bit dependencies. The only absolute unsolvable problem would be if this application included binary custom kernel drivers which aren't available in 64 bit, and if this was the case, I would hammer on the application vendor. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
