find latest version of rpms from a mirror
by john blair 10 Dec '09

10 Dec '09

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?

ntp update version
by Ron Yorston 10 Dec '09

10 Dec '09

I noticed that although I'd fetched the latest update to ntp from the mirror it wasn't being installed. It seems that the version numbers have got out of step. According to the changelog the update that was released in August should have had the version number 4.2.0.a.20040617-8.el4_7.2, whereas in CentOS it's actually 4.2.0.a.20040617-8.el4_8.2. The changelog says the latest update is 4.2.0.a.20040617-8.el4_8.1, which is what CentOS has, but that's a lower version than the August update. Ron

Linux router with CentOS
by Alvaro Schneider Guevara 10 Dec '09

10 Dec '09

Hello everybody. I'm wondering here if is it possible to setup a CentOS machine as a router for two Internet connections in a LAN. This _router_ would work as the gateway for the workstations using DHCPD. The purpose of this is to optimize the broadband "joining" both connections, and given the case, do not lose the Internet access. ¿is this possible? ¿too much complicated? Searching the Net i found something simliar: http://linux-ip.net/html/adv-multi-internet.html but, I would like to read a second opinion. Thank you very much. Cheers.

how to find last updates for Centos 5.3?
by Paul Johnson 10 Dec '09

10 Dec '09

I'm setting up a Rocks Cluster Linux system <http://www.rocksclusters.org> using Centos 5.3 as the OS. Rocks is an organizing framework for multi node systems, it tries to orchestrate kickstart installs across many systems and interaction among those many systems as a compute cluster. One problem with administering these systems is that the OS updates can break the Rocks framework. I've tried Rocks with Centos5.4, but there is some incompatability. The Rocks system is based on Centos 5.2, it tolerates 5.3, but not 5.4. The Rocks experts seem to discourage us from making any RPM package updates, but I'm adventuresome enough to think that I can at least try to make some selective updates. I wish I had access to a Centos update folder AS IT EXISTED before Centos 5.4 was released. The last update set that applied to 5.3,in other words. But I can't figure how to get that, because Centos servers just have the current updates under a folder marked 5. If I try to update against the current 5 server, it will pull in lots and lots of new RPMS from the Centos base, and I don't want that. I can't afford the risk of updating against the current Centos offerings because Rocks might not work anymore, or so I'm told by the Rocks experts. Any ideas about how to go back in time and get the last 5.3 update batch?? pj -- Paul E. Johnson Professor, Political Science 1541 Lilac Lane, Room 504 University of Kansas

Cent5 SELinux impacts on home exports when restoring from older systems are?
by Todd Denniston 09 Dec '09

09 Dec '09

I am working on moving some nfs shares from an older Linux system to CentOS5 server. some are used by the machine and its clients as $HOME (but not mounted at /home) and working directories. using selinux-policy-targeted. Are there any selinux policy additions (so restorecon keeps them each time it is ran) I should be looking to make before trying to slip the new system in under the users noses? that is besides setting to permissive, which I do not want to do. I am finding http://wiki.centos.org/HowTos/SELinux and http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-selinux.html of mild use.

Any way to initiate a kickstart from shell prompt?
by Spiro Harvey 08 Dec '09

08 Dec '09

Hi all, I've set up a CentOS flash stick using the LiveCD tools, then dumping that onto flash with a persistent overlay - instructions here: http://wtf.geek.nz/?blog/2009/12/08/how-to-make-a-useful-centos-utility-fla… This gets me to a prompt in which I can do recovery stuff, but I'm curious to know if it's possible to initiate a kickstart install onto the local disks from that prompt. I've got a separate stick that appends ks= lines to boot different kickstart files, but I'd really like to have the ability to do this on the non-auto-install stick too. Is this possible? Is there a command that kicks this off? Cheers -- Spiro Harvey Knossos Networks Ltd 021-295-1923 www.knossos.net.nz

Xorg goes bonkers, bazillion NVIDIA errors...
by fred smith 08 Dec '09

08 Dec '09

on one of my Centos 5.4 boxes, a machine that's around 5 years old and has always run Centos and X, and has had the same Nvidia card in it for its entire life, I'm suddenly getting these lines in the xorg log file: (WW) NVIDIA(0): WAIT (2, 6, 0x8000, 0x00000000, 0x000003c0) (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** followed by millions more like them. it's currently sitting mostly unused, except that it's running a Folding At Home client. it'll run for a day or a week then I'll note the screen is in powersave mode, will attempt to wake it up by moving the mouse or touching a key and nothing happens. (for purposes of this testing I've disabled the screensaver, so the screen should never shut off.) I can SOMETIMES ssh into it, if it hasn't completely died yet, and if I can, top shows that Xorg is consuming about 99% of the CPU instead of the folding at home client which should be consuming most of it. I guess it's busy spewing errors to the Xorg log file, or something. The last time I found it like this I tried to kill xorg. kill -15 wouldn't kill it so I tried kill -9, then the whole box seized up, requiring a reset. sometimes it's already unresponsive, even to ssh or ping, by the time I notice the problem. it's running an old Nvidia Geforce 4 MX400 card and the Nvidia proprietary driver NVIDIA-Linux-x86-96.43.01-pkg1.run, downloaded directly from the nvidia web site. the date on that file is Oct 2007, so that means that's the one that it has been using since then. but it's only the last 6 weeks or so it's started doing this. other than some vaguely-defined "nvidia driver problems", what may be going on here? (I can buy an nvidia conflict with the stock centos kernel, but I'd be dubious, since it's been running this driver for two years and earlier versions for 4 or 5. any such conflict would seem likely a kernel issue, to me, since it's newly exhibited.)

Hi - I updated firefox-3.0.5 from firefox-3.0.15on CentOS 4 this weekend and now I can't start it because it has the wrong version of NSS and I can't update NSS to the correct version. Does anyone know where I can find the RPM for CentOS 4 version of firefox-3.0.5? Or how I can tell yum to install version firefox-3.0.5 instead of firefox-3.0.15?

how to do startup scripts?
by Roland Roland 07 Dec '09

07 Dec '09

Hello, I've just finished installing Atlassian's bamboo it comes with two ways to start it up one through a bash shell script bamboo.sh and another through java script (this one is better as it has the ability to start up the service if it got shutdown for any reason) so I'm wondering how can I set this service to start on boot.. I know how to set a script on login in my profile though not on boot.. any suggestion? I've looked around about none interactive shells and so on.. so if I did a symbolic link from bamboo.sh script to /etc/init.d would that work? what about variables inside the script would they b read ? obviously a newbie here so appreciate any detailed explanation if possible about interactive/ none interactive shells and of course if theres an advice about how to solve this issue.. PS: trying to educate myself about linux along the way so any explanation would be greatly appreciated...

lvm monitoring
by Karanbir Singh 07 Dec '09

07 Dec '09

Hi, At the moment, I am monitoring my lvm resources on a machine with the usual 'pvs;vgs;lvs' output and comparing with whatever is a known good state. But this has a few problems: 1- I need to setup a known good state per machine, which can look quite different from each other : specially when machines are getting dynamic vm builds and teardowns dozens of times per day, or when disk resource allocations are spread over more than one machine. 2- Its hard to work out what is really going on with bits that are not mounted ( like snapshots ). 3- its hard to tie down to physical media ( I screen scrape at the moment, which is dirty and exceptionally prone to nose! ) I am sure there are plenty of people who are monitoring lvm setups on their machines, just wondering what it is that you guys are doing. - KB

I guess I forgot to include that some of those Linux systems I've used XFS on were 32 bit OS installs. However, lvm was not used on them, md & NFS were, but not lvm.

XFS is the most stable file system I've seen or used. I've seen it survive power failures and disk problems with out a problem. It is the ONLY file system I trust. It is stable, reliable, dependable, and practically bullet proof. I've been using XFS almost since it came into existence on SGI's (IRIX) and we've been using it under Linux for years too, also with out problems.

Kickstart wrong swap size
by Lars Hecking 07 Dec '09

07 Dec '09

All machines kickstarted here consistently have a swap partition with the wrong size. According to the RHEL5 manual: | To determine the size of the swap partition automatically, use the | --recommended option: | | swap --recommended | | The recommended maximum swap size for machines with less than 2GB of RAM is | twice the amount of RAM. For machines with 2GB or more, this recommendation | changes to 2GB plus the amount of RAM. However, the swap partition on all kickstarted machines is 2GB, regardless of RAM size. This is the relevant portion of the kickstart file: bootloader --location=mbr selinux --disabled reboot clearpart --all --initlabel part /boot --fstype ext3 --size=102 part / --fstype ext3 --size=20480 part swap --recommended part /var --fstype ext3 --size=1 --grow The kickstart setup is currently based on CentOS 5.2 (and I cannot move to 5.4 yet as this is a corporate setup affecting hundreds of machines). Hardcoding swap size isn't a good idea either because there's a range of different memory configurations. I could however confirm that a manual, graphical install from the 5.4 DVD with recommended settings creates 10GB swap on a 8GB RAM machine.

Resizing / partition ?
by armann 07 Dec '09

07 Dec '09

Hi. I know this has probably been discussed a lot so I'm sorry, noob here. I found a good tutorial here: http://fedorasolved.org/Members/zcat/shrink-lvm-for-new-partition My only problem is understanding this. "To calculate the new End sector, ADD the partition Start sector to the PV PSize, and then add a safety margin of around 131072 sectors (64MB) to that." If anybody has another way of doing this or any comments that would be great. Thanks. Armann Jakob Palsson

Name Resolution Broken for One Address

centos vs rhel vs scientific linux
by Robert P. J. Day 07 Dec '09

07 Dec '09

i'm prepping to teach a 5-day intro class in linux starting in about 3 hours, and the courseware is clearly designed around RHEL (apparently 5.1). but since i'm not being provided with RHEL DVDs, i'm just going to hand everyone a centos 5.4 DVD and take it from there. as part of the intro, i want to briefly discuss the varieties of linux related to RHEL, so obviously i want to mention what centos is all about. in a nutshell, it's simply RHEL with any RH-proprietary branding removed, yes? what's the simplest way to sum up the difference in a sentence or two? and i've never used SL but, again as i understand it, it's also RHEL unbranded but, IIRC, SL is more open to producing updates, whereas centos is rigourous about tracking the corresponding RHEL version. does that sound about right? rday -- ======================================================================== Robert P.

CentOS/RHEL's build of firefox hardwired to evolution -- how to change this
by Robert Heller 05 Dec '09

05 Dec '09

For some awful reason (can someone explain why?), the RHEL/CentOS build of firefox is hardwired to use evolution as its mailto client. With FF 2.<mumble> this was fixable with an about:config setting. With 3.0.<mumble>, it seems not. What is the proper way of fixing this? *I* ended up doing a 'sudo rpm -e evolution' and then doing a 'sudo ln -s <myfirefoxmailtohandler> /usr/bin/evolution'. This is a truely ugly/bad solution, but it is the only one I know of. Please tell be of a better solution. (Hopefully not one that requires me to download the firefox SRPM and hacking the .spec file -- re-building building firefox from sources is non-trivial -- I'd *rather* drop random symlinks into /usr/bin, bad as that is.) *I'm* tempted to report this as a serious *bug* (I really consider it so). -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/

if I: ssh -fND localhost:6000 somebody(a)192.168.56.5 -p PORTNUMBER from computer "A" to computer "B" [B = 192.168.56.5] then I can set the SOCKS proxy for e.g.: Firefox to use "localhost:6000" on computer "A". Ok. I can surf the web through "B". But: - Can anyone sniff the traffic of "A"? [e.g.: computers on same subnet as "A"] Like DNS requests? - I think no, but I'm not sure :O - Can anyone sniff the traffic of computer "B"? e.g.: B computer is at a server farm [others in the farm can see the traffic?] - I think yes, but I'm not sure :O

centos 5.4, firefox and adobereader plugin, disabled input fields
by Waldemar Gorus 04 Dec '09

04 Dec '09

Hello, we are using firefox-3.0.15 from the CentOS-Repository and the adobereader plugin from the adobe-repository. We have a curious problem with adobereader-plugin in firefox. When a pdf document is displayed via the plugin, i.e. within a tab in firefox, all input fields are disabled. I cannot enter a search string or fill in fields. The cursor and page up/down keys are also disabled. But when I configure firefox to open pdf documents with the external acroreader, everything works fine. Additional notes: * We are just migrating from SuSE. Some user profiles are working as expected without problems. Unfortunately, I was not able to figure out the important files: I traced all of firefox' file operations on the user profiles, but there are no significant differences between working and non-working profiles (I just compared filenames, not content). * the same adobe-plugin works with firefox 3.0.15 from mozilla.org * I also set up a clean i386-Centos 5.4 from original CD, SELinux disabled, updated and created standard user. I only added the adobe-repository. The same effect, no search avaible. I would be grateful about a solution (of course :-), but also for ideas on how to debug this problem. bye Waldemar

measuring iops on linux - numbers make sense?
by Amos Shapira 04 Dec '09

04 Dec '09

Hello, When approaching hosting providers for services, the first question many of them asked us was about the amount of IOPS the disk system should support. While we stress-tested our service, we recorded between 4000 and 6000 "merged io operations per second" as seen in "iostat -x" and collectd (varies between the different components of the system, we have a few such servers). A couple of hosting providers told us that this (iostat and collectd "merged operations per second") is a not so bad way to get IOPS. A partner of ours doubts that this is possible with the current hardware - a 3ware 9690SA-4I4E (http://www.3ware.com/products/sas-9690SA.asp) with 512Mb battery backed up cache and 8 SAS 15k rpm disks (SEAGATE ST3300656SS) in RAID 1+0. They calculate 750 IOPS per spindle and say that the maximum they ever saw from any 15k disk was 350 iops on RAID 0. Am I measuring the numbers correctly? Is there a better way to measure IOPS on CentOS? The OS is CentOS 5.3 x86_64, the rest of the hardware is 64Gb RAM, 2 quad-core 3GHz Intel Xeon CPU's. Thanks, --Amos

proper protocol for installing a *really* new package?
by Robert P. J. Day 04 Dec '09

04 Dec '09

what is the proper approach to install on centos 5.4 a package that's newer than the currently supported one? at the moment, AFAICT, the latest "poppler-utils" package for centos is 0.5.4. however, the source is up to version 0.12: http://poppler.freedesktop.org/ which matches the current fedora version, but that's not surprising since, naturally, fedora zips right along keeping up with that sort of thing. however, i have a case where it's important that a newer version of poppler-utils (and, consequently) poppler be installed on a centos 5.4 box. someone has claimed he's done it by (gack! choke!) installing the fedora package. that just creeps me out. in any case, what would be the proper solution under centos? is there a "rawhide"/dev equivalent for centos? thanks. rday -- ======================================================================== Robert P.

Centos 5.4 on Acer Aspire One
by Frank Cox 04 Dec '09

04 Dec '09

I currently have my Acer Aspire One netbook set up with Fedora 11. I would like to change it over to Centos 5.4 if I can. I downloaded the Centos 5.4 i386 livecd image and made a bootable USB flash drive out of it. Unfortunately, when I boot off of that flash drive, Grub (I guess) immediately turns the screen entirely white. If I hit a key I can faintly see the outline of "Press tab to change options" or words to that effect. (It's very faint and hard to read against the white background.) That bit of text rapidly scrolls off of the top of the screen, so I assume that the rest of the boot-up messages are being printed. Hitting Ctrl-Alt-anyFkey does nothing for a while, then every keystroke beeps. I can't get to a text terminal and I never see anything other than a completely white screen. Am I doing something wrong? Fedora 11 works fine on this machine, and I installed that from a livecd. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

Getting EXTERN.h, perl.h, etc
by Charles E Campbell Jr 04 Dec '09

04 Dec '09

Hello: I have a Fedora Core 11 system at home (Centos 5.2 at work). I'd like to build vim with huge and perl. This works under Centos, but fails at home: no EXTERN.h or perl.h (and, presumably, other things). So: is there a yum package I should be downloading, and if so, which one? (both the home computer and the work computer are 64-bit systems) Thank you, Chip Campbell -- someday I'll have a good signature, I'm sure of it...

"csh -v" show history at end of batch job (CENTOS 5.4)???
by mcclnx mcc 03 Dec '09

03 Dec '09

I have some batch JOBs migrate from CEBTOS 5.3 to CENTOS 5.4 server. Those batch files start on "#!/bin/csh -v". Those batch files run good under CENTOS 5.3. on CENTOS 5.4 batch jobs still run good but end of batch priocess it will show "history". Does anyone know why? Thanks. ___________________________________________________ 您的生活即時通－溝通、娛樂、生活、工作一次搞定！ http://messenger.yahoo.com.tw/

Kerberos + NFSv4 difficulties
by Dan Burkland 03 Dec '09

03 Dec '09

Hey All, I recently have been trying to setup an NFSv4 share that utilizes Kerberos. My experience in general with NFS is very slim however I feel like I am very close to getting this project completed. Currently I have the following things in place: 1) NFS server nfs.example.net (VM#2) - Running CentOS 5.4 with all of the latest updates and NFS-related packages 2) Kerberos KDC running on Kerberos.example.net (VM#1) - Running CentOS 5.4 with all of the latest updates 3) NFS client nfs-client.example.net (VM#3) - Running CentOS 5.4 with all of the latest updates Before I give you the error message I receive when I enable NFS, I'll first describe my setup process. 1) Verified Kerberos works on all machines by attempting a kinit testuser which worked properly. 2) Verified that the clocks on all machines represent the same time (synced using a local NTP server) 3) Created a service principle for nfs.example.net by performing the following commands on the nfs.example.net machine: - (Performed on NFS server) a. kadmin (Logged in as an admin principle) b. addprinc -randkey nfs/nfs.example.net c. ktadd -e des-cbc-crc:normal nfs/nfs.example.net d. quit e. kinit nfs/nfs.example.net -k -t /etc/krb5.keytab f. klist to verify 4) Edited /etc/idmapd.conf with the following changes: - (Performed on NFS server) a. changed Nobody-{User,Group} to nfsnobody b. changed Domain to nfs.example.net 5) Mkdir /nfs/ - (Performed on NFS server) 6) Added the following to /etc/exports - (Performed on NFS server) a. /nfs gss/krb5p(rw,sync,fsid=0) 7) exportfs -rv - (Performed on NFS server) 8) Verified all relevant nfs services were stopped - (Performed on NFS server) 9) Uncommented and made the following changes to /etc/sysconfig/nfs - (Performed on NFS server) a. MOUNTD_NFS_V1="no" b. MOUNTD_NFS_V2="no" c. RPCNFSDARGS="-N 2 -N 3 -U" d. SECURE_NFS = "yes" 10) /etc/init.d/portmap start; /etc/init.d/rpcidmapd start; /etc/init.d/nfs start - (Performed on NFS server) 11) And I receive the following output when the nfs service starts: a. Starting RPC svcgssd: FAILED b. Starting NFS Services: OK c. Starting NFS quotas: OK d. Starting NFS daemon: NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory e. NFSD: starting 90-second grace period f. Starting NFS mountd: OK 12) I then checked /var/log/messages to find the following log entries: a. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: ERROR: GSS-API: error in gss_acquire_cred(): Unspecified GSS failure. Minor code may provide more information - No principal in keytab matches desired name b. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: Unable to obtain credentials for 'nfs' c. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: unable to obtain root (machine) credentials d. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: do you have a keytab entry for nfs/<your.host>@<YOUR.REALM> in /etc/krb5.keytab? I seem to be stuck at this point and would appreciate your insight. Thank you, Dan
