Can not modprobe acpi-cpufreq.ko in CentOS 5.2
by Ian jonhson 03 Aug '09

03 Aug '09

Dear all, The cpufreq modules have been distributed in Centos. But recently, I met a problem when I tried to test the power-related applications. The module can not be modprobed in kernel notwithstanding releated with Centos distribution. The messgae thrown out is: ------------- dump of screen ------------ # modprobe p4-clockmod.ko FATAL: Module p4_clockmod.ko not found -------------------------------------------------- However, the module is there. If I search the kernel path: ------------------ dump of screen ---------------------- # ls /lib/modules/`uname -r`/kernel/arch/*/kernel/cpu/cpufreq acpi-cpufreq.ko # find /lib/modules/ -name "*cpufreq*" /lib/modules/2.6.18-92.el5/kernel/drivers/cpufreq /lib/modules/2.6.18-92.el5/kernel/drivers/cpufreq/cpufreq_powersave.ko /lib/modules/2.6.18-92.el5/kernel/drivers/cpufreq/cpufreq_ondemand.ko /lib/modules/2.6.18-92.el5/kernel/drivers/cpufreq/cpufreq_conservative.ko /lib/modules/2.6.18-92.el5/kernel/drivers/cpufreq/cpufreq_stats.ko /lib/modules/2.6.18-92.el5/kernel/arch/x86_64/kernel/cpufreq /lib/modules/2.6.18-92.el5/kernel/arch/x86_64/kernel/cpufreq/acpi-cpufreq.ko /lib/modules/2.6.29.3/kernel/drivers/cpufreq /lib/modules/2.6.29.3/kernel/drivers/cpufreq/cpufreq_powersave.ko /lib/modules/2.6.29.3/kernel/drivers/cpufreq/cpufreq_ondemand.ko /lib/modules/2.6.29.3/kernel/drivers/cpufreq/cpufreq_conservative.ko /lib/modules/2.6.29.3/kernel/drivers/cpufreq/cpufreq_stats.ko /lib/modules/2.6.29.3/kernel/arch/x86/kernel/cpu/cpufreq /lib/modules/2.6.29.3/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko # cat /etc/issue CentOS release 5.2 (Final) Kernel \r on an \m # uname -a Linux hdt0.mycompany.com 2.6.29.3 #1 SMP Thu May 28 13:34:23 CST 2009 x86_64 x86_64 x86_64 GNU/Linux ------------------------------------------------------------------ I have googled the internet for a long time, but not got any solution.

things weirdly different in new installation
by fred smith 02 Aug '09

02 Aug '09

I've just built a new system and installed latest Centos 5.3 on it. My old box also has an up to date Centos 5 on it. Some things are just plain different between the two installations, and it's stumping me why that would be. Example: on the old box, the shutdown dialog offers restart, cancel, shutdown, and also standby and hibernate. and the standby and hibernate options work, too. The new box, it only offers restart, cancel, or shutdown. Oddly, the main "System" dropdown offers "suspend" as well as "logoff" and "shutdown" submenus. Since it's a desktop, I won't often want to suspend or hibernate, but it may occasionally be nice to have the option to hibernate (e.g., power is off, UPS is about dead, hibernate could save my work.) Ideas, anyone?

Embedded Question
by Joseph L. Casale 02 Aug '09

02 Aug '09

A friend asked me to setup an embedded appliance with an RO root for minimal maintenance to primarily stream shoutcast out to an amp. The only thing I knew that might do this is iMedia Linux, but the project is practically dead with little to no activity. Is it possible to do something like this with CentOS? Doesn't seem to be much info on the /etc/sysconfig/readonly-root file. Anyone know a good place to get info on this? I would rather use CentOS if possible as I also want to use this a firewall/vpn for them and that would be easy and reliable w/ CentOS. Thanks! jlc

Centos convert to rhel?
by Bob Hoffman 01 Aug '09

01 Aug '09

Hate to ask, but after reading the last few months of centos history online I am worried. And to learn the lead guy seems to have absconded with the cash and left all the hard working devs high and dry..well that is scary. They all worked so hard and who knows what will happen now. If centos falls I have no choice but to go to redhat. I am wondering if the conversion will be easy or a complete reinstall. I ponder the worries I think we are all faced with here. I think all of us would follow a fork... Whatever they end up calling it. But I am worried about the immediate future for the project. None of those guys deserve what is happening to them and all of us are affected. If anyone lives near Lance, perhaps a good call to the local news station and some you tube stuff may get him to release the project to the team who wants to continue. But an option to go full redhat is one I am now considering.. Discuss?

Re: [CentOS] Open Letter to Lance Davis
by James B. Byrne 01 Aug '09

01 Aug '09

Since 2004 or so, I have donated each year to the CentOS project, at the requested rate, for each of our servers. While I never really gave the matter any thought (fool that I am) I presumed that any organisation that solicited funds would, at a minimum, be incorporated, have a board of directors, duly appointed officers and hold all corporate identity elements such as internet domain names, brand trademarks and such as corporate property. Evidently, my beliefs in this matter were sadly unfounded. Now, I appreciate that whilst somewhat embarrassing, the immediate matter is easily resolved, turning as it does on retention or depreciation of the centos.org domain. Presumably those who donated bandwidth and servers to the CentOS.old project will in the main continue to support the CentOS.new project. Equally, unless some injury that has not yet come to light has been done to them, it seems likely that most of the current maintainers will move their loyalties and future technical contributions to CentOS.new. However, having been bitten once, I feel that I must ask this more formal question. What steps, if any, have been taken to establish the CentOS project as a separate legal entity distinct from any individual contributor? What protections are being put in place to prevent future misappropriations of donations and advertising revenue, even if it turns out that no such thing has as yet happened? Sincerely,

how to disable scim
by Charles E Campbell Jr 31 Jul '09

31 Jul '09

Hello: I keep getting these An IOException occurred at scim_bridge_client_imcontext_set_cursor_location () messages -- and I'd like to turn them off. I won't mind having scim just plain turned off. However, in using Google, I find a hint such as "right click on the tray, ..." -- so where's the tray? A second part of that hint suggested using System:Administration:Language Support -- there's a "Language" (which allows me to select my default language) but nothing about scim. So, any hints about how to nuke scim? Regards, Chip Campbell -- someday I'll have a good signature, I'm sure of it...

Upgrade fm 4.7 to 5.3: mptscsi module?
by Curt Mills 31 Jul '09

31 Jul '09

First issue: I did an upgrade from 4.7 to 5.3 on an HP DL380G3 box. I got yum working again and upgraded 160+ packages. During that process I saw: ------------------------------------------- Installing : kernel-PAE [157/322] WARNING: No module mptscsi found for kernel 2.6.18-128.2.1.el5PAE, continuing anyway Installing : kernel [158/322] WARNING: No module mptscsi found for kernel 2.6.18-128.2.1.el5, continuing anyway ------------------------------------------- Since I'm running with SCSI drives on that box and lsmod shows me this: ------------------------------------------- # ./lsmod | grep mpt mptctl 31301 1 mptsas 37193 0 scsi_transport_sas 30529 1 mptsas mptspi 23625 0 scsi_transport_spi 26305 1 mptspi mptfc 21829 0 mptscsih 36929 3 mptsas,mptspi,mptfc scsi_transport_fc 37449 1 mptfc mptbase 76901 5 mptctl,mptsas,mptspi,mptfc,mptscsih scsi_mod 141589 17 mptctl,ib_iser,iscsi_tcp,libiscsi,scsi_transport_iscsi,scsi_dh,st,sg,mptsas,scsi_transport_sas,mptspi,scsi_transport_spi,mptfc,mptscsih,scsi_transport_fc,cciss,sd_mod ------------------------------------------- I'm a bit worried about rebooting the system. Should I be? Did some other driver take over the responsibilities of the mptscsi driver? Second issue: I also had to remove some repositories from yum, do a "yum clean all", and still manually remove a few more packages before yup update would work. There are still quite a few "el4" packages left on the system even now. History: # history 1006 yum update;date 1007 yum clean all 1008 yum update;date 1009 yum remove freetype-utils cyrus-imapd-murder cyrus-imapd-nntp 1010 yum update;date 1011 yum remove seamonkey 1012 yum update;date 1013 rpm -qa | grep -i el4 Some of the el4 packages that are left are probably one's that I installed by hand outside the yum repository scheme, but certainly not all of them are. I expected the upgrade off DVD and then the "yum update" to take care of most of those. -- Curt Mills, WE7U hacker at fluke dot com Senior Methods Engineer/SysAdmin "Lotto: A tax on people who are bad at math!"

LDAP howto using ds-base and ds-admin and related consoles
by Rob Kampen 31 Jul '09

31 Jul '09

Hi, I have previously used openLDAP and read many of their howto documents for establishing an LDAP server. RH and CentOS provide <brand>-ds-base and related rpms and I like what I see and read about the product. I found the wiki article on installing the rpms and getting it running on a server - so far so good. Then I fall into a big hole. What are the key items that need to be put in place to actually make it useful for my domain? Is there a document somewhere for those of us that want to bridge from openLDAP to the RH based product? I have read many hundreds of pages, have purchased O'reilly's LDAP System Administration but cannot seem to get my dirsrv based LDAP to function. I do understand that ds uses LDIF files to store and set things up, but seem unable to grasp the arcane entries that need to exist so I can access it with a basic LDAP client to load my users etc. Also I guess there are certain schemas that need to be used to allow basic functions to work. My wish list: linux user authentication and authorization windows user authentication and authorization (via samba?) customer contact list (name, address, company, phone numbers, email addresses) - this last one to be used by Thunderbird and my SIP phone system - both of which profess to speak LDAP I'm sure there are many small business folk that would like something like this, however I cannot find a template with all my searches, so for those of you with better LDAP and or google skills - please point me in the right direction. Thanks Rob
