Lock files in scripts
by Kenneth Porter 13 Jul '11

13 Jul '11

I was about to ask here how to do proper locking in a bash script when I found a page that addressed my objections to the race conditions I was finding in most sample code: <http://www.davidpashley.com/articles/writing-robust-shell-scripts.html> I just wanted to pass on the link to anyone else that needs this. One thing not addressed is how to deal with an orphaned lock file (eg. if the system crashes with the lock held). He stores the PID in the lock file, so one could look up the matching process and see if it's the script that's expected to create it. Otherwise one should be safe in deleting the lock file and trying again.

Setting hostname and network settings in 6.0 text mode installer
by Joe Mata 13 Jul '11

13 Jul '11

I'm doing my first 6.0 install the same way as I've always done my server installs -- in text mode. But it looks like there's no option to do the following in the 6.0 text mode installer? * Set hostname * Set network settings * Choose packages I really hope I'm missing something because having to use a GUI to install a server is incredibly painful.

EL4 and spamassassin info
by R - elists 13 Jul '11

13 Jul '11

greetings, have been google foo for week or so. used to be super easy to upgrade spamassassin on CentOS dist. just grab the tarball and put in right spot and rpmbuild -tb spamassassin-3.somethingsomething.tar.gz then rpm or yum install and done would take just a few minutes. Yet... in regards to EL4 / CentOS 4 and spamassassin, it appears the end of the road for .spec in SA tarball evidentally some admins had a hard time doing the above for some perl issues. we havent had urgent need to upgrade one of our legacy mail servers that is still on 4. that will change of course with Centos6 out now. this is, did anyone roll a spamassassin 3.3.2 for CentOS4 / EL4 yet? tips or share rpms please? - rh

make install?
by hadi motamedi 13 Jul '11

13 Jul '11

Dear All I downloaded the octave-3.4.2 and tried to install it on my centos 5.6 as the following: #./configure But it prompted for lack of a c compiler, so I tried to install gcc first and then re-executed it and it was successful. #make But it prompts as "No targets specified and no makefile found". #make install But it prompts as "No rule to make target 'install'". I had the same steps for installing applications when I was on my centos 5.0 machine. Can you please let me know what is wrong my case? Thank you

For example, in anaconda there is an install group called "Minimal Desktop" If I look in the comps.xml in the centos repo there is no such group. There is also a Minimal group that does not appear in comps. All I am trying to do is understand the relationship between the groups listed in anaconda and in comps.xml. Does anaconda use a different comps.xml? Regards, -- Tom Diehl tdiehl(a)rogueind.com Spamtrap address mtd123(a)rogueind.com

Using FreeIPA Server V2 and began testing against CentOS6 since it has a better support for SSSD.

Easy switch from Fedora 14 to CentOS 6??
by Beartooth 12 Jul '11

12 Jul '11

Of course I can switch, I know, by brute force : just install CentOS over top of Fedora. But that would require a tedious day (of manually re-tweaking panels, adding & removing software, etc. ad nauseam, *and* transferring a backup copy of my data back onto the machine) -- which I'd prefer to avoid. What I want to do, if I can, is emulate the upgrades I've been doing with each new release of Fedora. I'm hoping, since the like can be done from SL, maybe it can also be done from Fedora. (Minor footnote: if Fedora has any browser I don't run, it's an oversight on my part. I realize most aren't available, or at least not as rpms, for CentOS; I'm willing to make that sacrifice.) -- Beartooth Staffwright, Not Quite Clueless Power User I have precious (very precious!) little idea where up is.

by david 12 Jul '11

12 Jul '11

Dear Gurus Thanks for the responses. I'll summarize what I've learned trying to install Centos6 on a Dell Optiplex GX 240 Review: a) I decried the lack of CD images for Centos6. b) I was informed that it's unlikely they'll be produced due to an upstream decision. c) I pointed out that the machine only had floppy, CD and HD boots capability. d) I got a suggestion to use the network method. Results: 1) PXE boot might work, but it seems that it's a lot of trouble setting up a PXE server. I'm still working on it. 2) The NET-INSTALL indeed did work, with the following gotchas: 2a) The URL to enter is not obvious. 2b) I tried the one at Stanford, and at uidaho, but they failed. 2c) Finally, http://mirror.centos.org/centos/6.0/os/i386 worked. 3) SInce I had only a text install, various interesting and important programs were missing: ssh (which apparently is masquerading under the name "openssh-clients"), ftp and perl, which YUM got for me. 4) The module perl-Digest-MD5 was not in the repository. Was its removal intentional, or is it hiding in some other Centos6 repository? 5) The line-by-line notation during bootstrap is no longer shown. This makes it difficult to detect where hangups occur during the bootstrap process. Is there a way to display those notations in real time? Conclusion: I'm still trying David

Web page creates a temp file saying "update", then cron job runs once a minute looking for that file, kicks off update script, then deletes temp file. If you don't want to wait a full minute you could use 'incron' to monitor the temp directory and kick the update right away.

Hard disk installation
by Timothy Murphy 11 Jul '11

11 Jul '11

Has anyone installed CentOS-6 from the hard disk? I just tried this without success. I should say that I asked the question before about CentOS-5.6, and while I got many suggestions in reply, no-one actually said that they _had_ installed CentOS this way. What I did was to "mount -o loop" the DVD iso (which I checksum-ed) and copy isolinux/vmlinuz and isolinux/initrd.img , as well as the images/ directory, to /boot , and then added a simple stanza ------------------------ title CentOS-6 root (hd0,1) kernel /vmlinuz text askmethod initrd /initrd.img ------------------------ The machine - I should have said that it is an HP MicroServer - boots fine, until it gets to "Waiting for hardware to initialize", at which point the screen goes blank and nothing appears to happen. I should say that the machine is running under CentOS-5.6, which I installed with a USB stick. I'm trying to install CentOS-6 on another partition. I shall try the USB stick method shortly. But I would be interested to know if anyone has actually installed CentOS-6 from the hard disk, and if so how. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

I won't repeat what first entered my head, but I couldn't help but laugh and think, "How the hell can there be updates already for an OS that just got released?" -- Mark Weaver Computer Information Systems & Services, Inc. mweaver(a)compinfosystems.com (717) 512-9718

11 Jul '11

Hi List, This morning while setting up C6 on my laptop this morning I attempted to download and install Yumex, but the repos returned no results for this package. Has this been discontinued and if so, what package manager should I be looking for? thanks, Mark

Deleting a KVM virtual machine from the command line
by Sean Carolan 11 Jul '11

11 Jul '11

I am working on a sandbox machine that will allow users to play around with building virtual machines, then blow them all away each night with a cron job. I wrote a small script that uses the virsh command to destroy the VMs, then remove the storage. For some reason the vm name still shows up in the virt-manager GUI. Anyone have an idea how you delete it from there as well, without using the GUI? thanks Sean

CentOS 6 and pxeboot
by m.roth＠5-cent.us 11 Jul '11

11 Jul '11

Well, I started the install, got pxeboot to get to the kickstart file, formatted the drive... and then it failed, telling me "unable to read group information from repositories. This is a problem with the generation of your install tree." A quick google gives me the first hit from a year ago, bug 4372 <http://bugs.centos.org/view.php?id=4372>, which says there's a metadata problem. Has anyone else run into this today? mark

how to enable Flow Control on CentOS?
by Rudi Ahlers 11 Jul '11

11 Jul '11

Hi, I have an interesting situation with one of our switches. It's a D-Link DGS-3100, 24 port 10/100/1000 Layer 2 Managed switch with some CentOS servers connected to it. On many of the servers I need to disable Flow Control on the switch's ports otherwise the CentOS server's doesn't connect to the switch. i.e. the Switch indicates that the LAN cable is unplugged and CentOS can simply not connect to any host on the LAN. As soon as I disable Flow Control, CentOS "breaks". Does anyone know why this would happen, or how / if I can enable Flow Control in CentOS as well? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

When i boot my HP ProLiant DL380 G4 from the stick, the CentOS boot screen comes up and and the message "Automatic boot in xx seconds..." appears. * When i do not hit any key, the seconds are counted to zero an then it starts again at 10 seconds - again and again. * When hitting return, a boot menu appears: 1) Boot 2) Boot (text mode) 3) Network Installation 4) Memory-Test 5) Boot from local drive Only Options "Memory-Test" and "Boot from local drive" work. When choosing Option 1,2,3 i'm always pushed back to the menu. How to install CentOS vom the stick? Please help me to find my mistake. Please tell me, if i can provide any information. Bye, Florian

Today's Topics: 1. Release for CentOS-6.0 i386 and x86_64 (Karanbir Singh) ---------------------------------------------------------------------- Message: 1 Date: Sun, 10 Jul 2011 19:51:21 +0100 From: Karanbir Singh <kbsingh(a)centos.org> Subject: [CentOS-announce] Release for CentOS-6.0 i386 and x86_64 To: CentOS Announcements List <centos-announce(a)centos.org> Message-ID: <4E19F4A9.1050204(a)centos.org> Content-Type: text/plain; charset=ISO-8859-1; format=flowed We are pleased to announce the immediate availability of CentOS-6.0 for i386 and x86_64 Architectures. CentOS-6.0 is based on the upstream release EL 6.0 and includes packages from all variants. All upstream repositories have been combined into one, to make it easier for end users to work with. There are some important changes to this release compared with the previous versions of CentOS and we highly recommend reading this announcement along with the Release Notes at http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.0 There are no CD images being released with CentOS-6, however we have some CD variants in the pipeline. Details for these are mentioned below. Since upstream has a 6.1 version already released, we will be using a Continous Release repository for 6.0 to bring all 6.1 and post 6.1 security updates to all 6.0 users, till such time as CentOS-6.1 is released itself. There will be more details about this posted within the next 48 hours. +++++++++++++++++++++++ Upgrading from CentOS-4 or CentOS-5: We recommend everyone run through a reinstall rather than attempt an inplace upgrade from CentOS-4 or CentOS-5 +++++++++++++++++++++++ LiveCD and LiveDVD LiveCDs and LiveDVDs for i386 and x86_64 will be released within the next few days. These will bring in the ability to directly install from the livemedia. +++++++++++++++++++++++ Minimal Install CD We have also created a minimal install CD, that would bring up a base machine with just enough content to have a usable platform. This CD image will be released in the next few days. +++++++++++++++++++++++ The LightWeightServer (LWS) CD In order to bring back the CentOS-4 Server CD style single iso image, we are creating a LWS varient of the main distro. Details for this will be posted in the next few days with release happening after the live media and the minimal cd editions. +++++++++++++++++++++++ Downloading CentOS-6.0 for new installs: When possible, consider using torrents to run the downloads. In most cases you will find its also the fastest means to download the distro. There are currently over a thousand people seeding CentOS-6 and it's possible to get upto 100mbps downloads via these torrents. Torrent files for the DVD's are avilable at : http://mirror.centos.org/centos/6.0/isos/i386/CentOS-6.0-i386-bin-DVD.torre… http://mirror.centos.org/centos/6.0/isos/x86_64/CentOS-6.0-x86_64-bin-DVD.t… You can also use a mirror close to you : http://www.centos.org/modules/tinycontent/index.php?id=30 Most mirrors will allow direct DVD downloads over http, ftp and rsync. Please keep in mind that not all mirrors are currently updated, some might take upto another 24 hours before they have all the content. +++++++++++++++++++++++ sha1sum for the CentOS-6.0 ISOS: i386: fcf49e875cd4494f2af68cf257ab9e93523c9427 CentOS-6.0-i386-bin-DVD.iso 862815623d2e7990207dd78a281837c7eb719e83 CentOS-6.0-i386-netinstall.iso x86_64: 9de87b0c696ebd72b952edb4cc06c24cbdc37d81 CentOS-6.0-x86_64-bin-DVD1.iso 5e3834621f11fbcca78cf7d70625c647045f45f5 CentOS-6.0-x86_64-bin-DVD2.iso 23f9e606cbcbd52d2e5df3716a85cdde336f7bfe CentOS-6.0-x86_64-netinstall.iso +++++++++++++++++++++++ Sources and Debuginfo packages: SRPMS and debuginfo packages are still making their way to the CentOS mirrors and should be available within the next 24 to 48 hours. We are prioritising the centos modified packages. +++++++++++++++++++++++ Getting Help: The best place to start when looking for help with CentOS is at the wiki ( http://wiki.centos.org/GettingHelp ) which lists various options and communities who might be able to help. If you think there is a bug in the system, do report it at http://bugs.centos.org/ - but keep in mind that the bugs system is *not* a support mechanism. +++++++++++++++++++++++ Contributing and joining the project: We are always looking for people to join and help with various things in the project. If you are keen to help out a good place to start is the wiki page at http://wiki.centos.org/Contribute . If you have questions or a specific area you would like to contribute towards that is not covered on that page, feel free to drop in on #centos-devel(a)irc.freenode.net for a chat or email the centos-devel list (http://lists.centos.org) +++++++++++++++++++++++ Thanks to everyone who contributed towards making 6.0 Enjoy! -- Karanbir Singh <kbsingh(a)centos.org> The CentOS Project {http://www.centos.org} irc: z00dax(a)irc.freenode.net ( #centos, #centos-devel ) ------------------------------ _______________________________________________ CentOS-announce mailing list CentOS-announce(a)centos.org http://lists.centos.org/mailman/listinfo/centos-announce End of CentOS-announce Digest, Vol 77, Issue 4 **********************************************

Congratulations to the Centos Team for the hard work on Centos 6
by Philip L Pinto 11 Jul '11

11 Jul '11

I just wanted to say Congratulations and thank you to the Centos Team for all of the work on Centos 6 - I know the last few months have not been easy - but the real benefit will be that Centos 6 will be as good and as stable as Centos 5 has been for me and everyone who has been using it for the past 4 years. It has never a matter of just getting it done - but getting it done right. Thank You Phil -- This message has been scanned for viruses and dangerous content.

CentOS-6, isos and release
by Karanbir Singh 11 Jul '11

11 Jul '11

hi guys, I appreciate that the visibility of centos-6 content is highly tempting and many people are going to be jumping in to get on there asap - however, I just want to point out that till its released, its liable to change. And I can *confirm* that content presently visible is going to change. So hang in there, give it another day or so - dont do the installs till the mirror system is online, till the sha sum's for content is published, till the torrents are available. - KB

More on CentOS autotools bug
by John J. Boyer 11 Jul '11

11 Jul '11

Below is a repost of the message I sent about the strange error message I was getting when trying to build my project on CentOS. I am a software developer and don't have time to compare distros. I am also not an autotools expert. The autotools files in my project were lmade by others. It builds on everything except CentOS. I also don't have the time to build a simple test case. That would probably be time-consuming. The only thing I can do is explain how to reproduce the error. However, this would be time-consuming for anyone trying to do so. Sorry, I think I will just have to move to another distro, even Cygwin, for C development. That is a shame, because Centos is great in other respects. ----- Forwarded message from "John J. Boyer" <john.boyer(a)abilitiessoft.com> ----- Subject: Strange autotools error From: "John J. Boyer" <john.boyer(a)abilitiessoft.com> Date: Thu, 7 Jul 2011 00:08:09 -0500 To: centos(a)centos.org I am using CentOS 5.6, autoconf 2.59 and automake 1.9.6. I run an autogen script which cleans all autotools files and then installs new ones. If the appliction has no dependencies running configure, make and make install works fine. However if it has dependencies I get the messages "Creating Makefile" and "Could not find input file Makefile". I've herd that I need another development package. What is it? Or what causes these contradictory messages? I must say that I have encountered this sort of problem only on CentOS. Thanks, John -- John J.

Translate Centos Release Notes into your own non-English Language
by Always Learning 11 Jul '11

11 Jul '11

Centos 6.0 Release Notes are here http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.0 Volunteers whose native (or first language) is not English are invited to translate the Release Notes into their own language. There are probably other useful translation tasks to make Centos understandable to people all around the world. Should the Centos Mailing List diversify into non-English language versions ? For example, Chinese (which version?) , Spanish, Portuguese, Russian, Serbian etc. etc. ? For example: chinese(a)centos.org -- With best regards, Paul. England, EU.

centos 6 (what else? :) :)
by fred smith 11 Jul '11

11 Jul '11

Hi all! My thanks to the Centos team for continuing to slave away on C6 even with all the distractions!!! Just did a test install on my eeepc 901 (on an external drive, til I'm comfortable with it) and find that it doesn't seem to know how to talk to the ralink 2860 wireless chipset. A few months back I did a test install of Scientific Linux 6 and as I recall it (I may be mis-remembering) it "just worked". So I enabled EPEL and RPMFUSION but they don't seem to have the driver either. Clues appreciated. Thanks again to all to work on this! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- "For the word of God is living and active.

Upgrade from CentOS 5.x to 6.0
by Trey Dockendorf 10 Jul '11

10 Jul '11

Great news about CentOS 6.0 being available, and I figured I'd ask the most obvious question, what can I expect when upgrading from CentOS 5.6 to 6.0? I have not had to go from one major version of CentOS to another so this is new territory for me. Is the processes just like an install except there's an "Upgrade" option? Does an upgrade do a "yum update" of everything installed? Most of my systems use EPEL and some the IUS repos...is there a way during the upgrade to just upgrade system components and leave things like PHP, httpd and MySQL alone for now? Any suggestions on monitoring the upgrade progress via syslog or some other method so I can see exactly what is being done during the upgrade? Thanks - Trey

CentOS and Bandwidth
by Michael Peterson 10 Jul '11

10 Jul '11

I am looking forward to using CentOS 6 soon. I have the torrent running to download and help others download it. I am trying out Scientific Linux 6 while awaiting the arrival of CentOS 6. It took a lot of work to get it installed and configured on a system. I plan to run them both on 2 systems and see what happens. I look forward to the release of CentOS 6.1 soon also. Let me know where I can browse to see if I can help in any areas other than the torrent. If I have a T1 size pipe going out what is my max possible kB out? I have the torrent turned up to 100kB and my VPN still seems responsive. Thanks for all the hard working in getting this release ready. Good job on getting CentOS 5.6 out first however.
