Re: [CentOS] Why slapd dying?
by Jun Salen 19 Jan '07

Thanks Johnny. My Slapd are now running after start thru service start command. One of the reason why the daemon is dying before is that the dbd database was corrupted probably by sudden power off due to lose power socket connection. I follow your advise and now enable logging thru it.

Apache 2.2 under CentOS?
by Peter Serwe 19 Jan '07

19 Jan '07

We've been going through some growing pains fumbling through porting some custom C modules that used to live under apache 1.3 into the 2.0 spec, even though none of us really considers ourselves a 'C developer'. We've basically got them all working now under the 2.0 API, and the question was posed about whether or not we should consider attempting to upgrade everything to run under httpd-2.2. I noticed the httpd2 port is only 2.0.53 under CentOS, and I was wondering why that is? Is there a 2.2 port? Is there plans to do one? Was it tried and found that there are significant obstacles in the way of getting 2.2 to run under CentOS 4.4? Is there a port of 2.2 planned for 5.0? Is it a question of resources, and should we undertake it, do you guys want the resulting i686 RPM's? Comment Karanbir?

centos driver disk?
by Steve Huff 18 Jan '07

18 Jan '07

the recent discussion of support for Promise SATA drives reminded me that a while back i remember reading about a project to assemble a driver disk to provide wider hardware support than just stock CentOS. how's that coming along? i don't see anything in the wiki about it... as i have a vested interest in this project (since i'm still relying on old MegaRAID controllers), i'd be willing to help out with it. what's the current status, and what needs doing? thanks, -steve -- If this were played upon a stage now, I could condemn it as an improbable fiction. - Fabian, Twelfth Night, III,v

I have a machine with many file system errors. I booted into rescue mode - I tried to run "e2fsck -p /dev/hda1" but it says something about inconsistency and cannot run with -p. So then I just run "e2fsck /dev/hda1" and I have to answer MANY fixes with a "y". How can you just tell it to fix it and dont ask? I'd hate to say how many 'y' I have answered. The filesystem is ext3, I was surprised this even happened. Jerry

centos version numbers
by Melinda Odom 18 Jan '07

18 Jan '07

Hi, I am running centos 4.2 version on my server. The /etc/redhat-release file lists centos 4.4 (final). In my Plesk server administration it also shows centos 4.2. I need to upgrade plesk and am suppose to have centos 4.3 to do this upgrade. In the past I have run "yum update" and the OS was always updated to the next version but this no longer works on my server. When I try yum update or yum upgrade there is nothing to update. I have checked some of the files from the centos mirror site for version 4 and it seems I have the same versions on my server. http://mirror.centos.org/centos/4/os/i386/ So would I have the most recent centos version?

Machine all of a suddens freezes. Any suggestions?
by Theo Band 18 Jan '07

18 Jan '07

This is a A8N32-SLI Deluxe motherboard with a AMD Athlon(tm) 64 X2 Dual Core 4400+ Processor. It freezes and cannot be accessed from the network. Keyboard/mouse/display, everything just stuck. It had an uptime of 17 days after I re-connected all cables and boards after a similar crash. My feeling is, this must be a hardware related problem. I inspected the logs under /var/log, but nothing. What would be the best approach to debug this problem? What can be the most likely cause? Or should I just accept it (it's a single user desktop machine). The machine has FC4 installed. Is there a chance that it becomes more stable with Centos (as said, I actually don't suspect the OS). For new machines I started installing Centos (and I'm happy with it, especially the fact that my EDA software vendors support it well). I monitor the machine with Zabbix, but no weird things there. Just before the freeze the machine had a processor load of 1 running a user simulation. Any suggestions would be welcome. Thanks, Theo

Temperature could indeed be the case. The last time it happened was during heavy load. The fans are spinning, that I checked already. I will add temperature monitoring as well to the logs.

Entourage X and Sendmail STARTTLS on CentOS 4.4
by Paul R. Ganci 18 Jan '07

18 Jan '07

I have a user who has Mac OS 10.4.8 with Entourage X. The email server is sendmail 8.13.8 and is setup to use STARTTLS on a CentOS 4.4 system. It appears from everything I have googled that only Entourage 2004 will properly function with STARTTLS. Has anybody any experience with Entourage X ... specifically is there something I am missing regarding the CentOS server setup or are all Entourage prior to the 2004 version indeed broken in regards to STARTTLS? I have just done the usual stuff that seems to work for Thunderbird, Evolution, Outlook, Mac Mail and the latest Eudora. On the sendmail server side: define(`confAUTH_OPTIONS', `A p y')dnl TRUST_AUTH_MECH(`LOGIN PLAIN')dnl define(`confAUTH_MECHANISMS', `LOGIN PLAIN')dnl (purposely not showing the certificate config) On the Entourage X client side: Checked the box "SMTP service requires secure connection (SSL) Checked the box "SMTP server requires authentication Checked the box "Use the same settings as receiving mail server" Entourage X returns an error indicating: "The SMTP server for "MRIC" does not recognize any of the authentication methods supported by Entourage." Can anyone verify that Entourage X does not work with STARTTLS and/or suggest a work around? I am hoping that upgrading to Entourage 2004 is not the only answer. Thanks for you rhelp. -- Paul (ganci(a)nurdog.com)

syslog strangeness
by exilemenot 18 Jan '07

18 Jan '07

I'm setting up a server and noticed syslog has stopped putting messages into secure, maillog, and messages. syslog.conf is stock, and both it and klogd are running. This occurred around the same time I put the IPTables config in the box, but disabling iptables doesn't seem to make any difference. I'm doing things that should generate traffic to those files. Cron jobs have also appeared to stop running as well. Reinstalling the box would be difficult, so any advice would be appreciated on where to look. Thanks

Changing the contents of installation cd so as to include a new kernel
by Janice D'Sa 18 Jan '07

18 Jan '07

Hi, I have CentOS 4.4 with me. I want to change the default kernel during installation, from 2.6.9 to 2.6.15. I got myself a copy of vmlinuz and initrd.img from the RHEL AS 4.0 installation cd and copied it as vmlinuz-rhel and initrd-rhel.img respectively into the isolinux folder on the CentOS cd. I changed isolinux.cfg so that it would boot into my kernel. I then made a fresh new ISO and tried to boot off it. However, when I boot I get the following error "Cannot find kernel image: vmlinuz-rhel". I cant figure out where the boot loader is looking for vmlinuz and initrd (besides the islinux directory) and if there are any other norms that Im not sticking too. Thanks, Janice. __________________________________________________________ Yahoo! India Answers: Share what you know. Learn something new http://in.answers.yahoo.com/

Centos 4.4 install on ASUS A8V-VM does not find SATA drives
by Don Levey 17 Jan '07

17 Jan '07

Yes, I know someone last week asked a similar question (Problem with ASUS P5VD2-X X SATA II) but the only answer I saw on that thread was the equivalent of "I've heard it's bad so I won't do it." Unfortunately, that doesn't help me much. The BIOS does indeed recognise my two SATA hard drives, and I've got the BIOS set to "IDE" (which disables "hardware" RAID but not the SATA but itself). The install routine for Centos, however, does not seem to recognise that the drives are there (or even that the VIA bridge exists via auto search); if I try to manually select it I'm told it found a VIA VT86c100A Rhine-II PCI (via-rhine). Setting to AHCI does not seem to have an effect. I was hoping to use software RAID, and so didn't want to enable RAID on the motherboard. Does anyone have any suggestions as to how to either nudge the installation, or configure the hardware, to find the SATA drives so I can configure RAID? This is a NEW install on new drives, so it's not as if I've got an existing configuration I'm trying to augment. Thanks in advance, -Don

dhcpd errors
by Kanwar Ranbir Sandhu 17 Jan '07

17 Jan '07

Hello Everyone, I'm running a dhcp server on CentOS 4.4. It's providing IPs and remote booting for a number of thin clients. I've recently had problems rebooting a few thin clients. Here is the error I've been seeing: Jan 16 14:16:45 at01 dhcpd: DHCPRELEASE from 00:40:63:e5:71:4f specified requested-address. Jan 16 14:16:45 at01 dhcpd: DHCPRELEASE of 10.1.1.150 from 00:40:63:e5:71:4f via eth0 (not found) Depending on the thin client, the MAC and the IP changes. Otherwise, the errors are all the same. The effect on the thin client end is that it doesn't get an IP, and so it doesn't boot. The usual remedy is to unplug/plug-in the cat5 cable at the thin client, or to move the thin client to another network drop. This has me thinking there's a problem with the cat5 cabling (the office is going through a major renovation). But, I'm not 100% that is the case. It could be a problem with the dhcp server. I don't have easy access to that office - it's remote, and I'm only out there once every few months. It's why I want to make sure it's not a software problem first. At the moment I have no clue what's going on. My searching with google hasn't turned up anything useful. I'd appreciate any comments/suggestions.

Dual Heads?
by Peter Serwe 17 Jan '07

17 Jan '07

I decided to blow out the FC2 installation I inherited on my workstation when I started here and installed CentOS-4.4-i386. Server side stuff I pretty much have down cold, but getting two heads on two seperate video cards doesn't seem to work for me. I'm using the built in Intel 865/810 card as primary, and an ATI Radeon 9200 PCI card as secondary. Initially, my system bios on this Dell 4600 was set to Auto for which card is primary. That made the ATI card primary. Configuring the 865 card as secondary, and I have the same monitor on both heads, didn't seem to do anything for me. Then, I set the onboard video as primary, went back into system-config-display and configured the ATI card as secondary, logout/login still nothing changed. I'm trying to get it to configure as 'spanning desktops', so I just have twice as much real estate, and ideally can drag in between. Anyone have suggestions? Also, in general, the wm is pretty bland, so suggestions to make it a little more fun would be good too. :) Peter -- Peter Serwe <peter at infostreet dot com> http://www.infostreet.com "The only true sports are bullfighting, mountain climbing and auto racing." -Earnest Hemingway "Because everything else requires only one ball." -Unknown "Do you wanna go fast or suck?" -Mike Kojima "There are two things no man will admit he cannot do well: drive and make love." -Sir Stirling Moss

Naive suggestions for (kinda) funding
by Radu-Cristian FOTESCU 16 Jan '07

16 Jan '07

First of all, don't shoot me if I got some things wrong. I personally recommend (without much success :-)) to buy from www.cheeplinux.com (Definite Software), because I believe this is of some help to the CentOS project. At least, to some people involved in it (please correct me if I'm wrong). §1. Anyway, as PayPal is _not_ an option for some countries, donations to CentOS.org can't be done by PayPal. I suggest to add an item "donate to CentOS: GBP 1" to www.cheeplinux.com, the same way Slackware has an item of $1, so you can "buy" as many of these to donate. Moving on: www.cheeplinux.com is by no means "the cheepest", on the contrary. From the three virtual stores I trust (and I have used), we have e.g. (shipping is extra): * 2 CDs on cheeplinux.com US$14.75, and they're paper-printed on the face; * 2 CDs on thelinuxstore.ca US$7.70, and they're ink-printed(!) on the face; * 2 CDs on linuxcd.org US$3.50, and they still work :-)) (plus they constantly have new items); Again, I am "pro-cheeplinux.com" in the hope this helps the CentOS project. §2. For that price, to have a real success, Cheeplinux should try ink-printing on the CD/DVD surface, like the Canadians do. Properly adverstised, sales should increase noticeably, and they should compensate the increased production costs. §3. Cheeplinux is also the only place where one can find such cute things like the CentOS PC badge #2: http://www.cheeplinux.com/product_info.php?products_id=210 My suggestion is to try to add some more CentOS-specific/uniquely-branded stuff. Take a look at some interesting products made in Brazil, carrying Red Hat's branding (most likely, illegally): -- a superb pin, 23 x 23 mm: http://www.linuxmall.com.br/index.php?product_id=982 -- a great rollerbal: http://www.linuxmall.com.br/index.php?product_id=2421 You could try to cut a deal with these Brasilieros to produce _CentOS-branded_ stuff of the same quality. They could ship bulk quantities to the UK, for sale through Cheeplinux.com. A good thing is that LinuxMall.com.br does NOT sell to Europe (except for Portugal), and... their site is in Portuguese only!!! So no, no real competition :) So, should you get such a pin for GBP 1 (R$ 3.90 make GBP 0.93), you might sell it with something like GBP 3; the rollerball at ~GBP 3.30 could sell at GBP 10, and these are only for the specified items. That is, similar items, CentOS-branded! Ask me in private for the e-mail of a contact person at LinuxMall.com.br who can speak English (well... sort of, but good enough). Maybe they will cooperate. (Ach! please note how cute their CDs/DVDs are printed!) R-C F aka Béranger --------------------------------- All new Yahoo!

Server Install Eth0 & Eth1 not working
by Ed Morrison 16 Jan '07

16 Jan '07

Hi Everyone: I installed CentOS 4.4 on a new Dell 2950 using the server cd. No errors during the installation and no errors on bootup when loading the Eth0 or Eth1 interfaces. I currently have iptables stopped and selinux disabled. The interfaces have been given a static ip (192.168.1.x). the subnet is 255.255.255.0 and the gateway is 192.168.1.1. I can not ping any device on my network including the gateway. I can ping 127.0.0.1 and the 192.168.1.x. After trying to ping another device ifconfig will show that on ifcfg-lo transmit and receive packets of 389 or some other number depending on how many ping packets were sent. Ifcfg-th0 or Ifcfg-eth1 will not show any TX or RX packets. The box was ordered to support RH from Dell. The NIC is an embedded dual port Broadcom NetXtreme II5708 GigabitEthernet NIC. I've replaced all network cables and the ports to where they connect into the switch and even a different switch and it still will not show me any love. Any ideas would be welcome! Thanks Ed

slow system
by Craig White 16 Jan '07

16 Jan '07

I have a server that is running slowly and I think it's because of my stupidity - it's running CentOS 3.8 I have software RAID level 1 and the mirrored drives are the master & slave on the primary controller and I'm thinking that is my mistake. Is there a simple method for changing the configuration of md before I switch the slave drive to be the slave on the secondary controller? Craig

Hi, I've got a couple of machines acting as directors with service=lvs Is there something similar to 'clustat' for pulse+lvsd? I need this in order to make our monitorization scripts "cluster-aware", or else one node will have critical status when there are less nannies than it expected because the services ran over to the other node.

CentOS 4.4 on mini-itx
by Tom Diehl 15 Jan '07

15 Jan '07

Hi, I have a EPIA mini-itx board that I have been running Fedora 4 on. I want to install CentOS 4.4 on it since FC4 is no longer supported. The install goes fine but when I reboot the machine after the install I get errors like the following: hda:<4>hda: dma_timer_Expiry : dma status == 0x21 There are other errors about not being able to access the disk and eventually the kernel panics. The disk is a 4 gig compact flash. I used a 1 gig chip for FC4 so I know the thing will run from a flash chip. Does anyone have any idea how to get this to work? Is there a way to turn off dma? Has anyone else tried this? Regards, -- Tom Diehl tdiehl(a)rogueind.com Spamtrap address mtd123(a)rogueind.com

RHCS on CentOS4 - 2 node cluster problem
by Alexander Dalloz 15 Jan '07

15 Jan '07

Hello fellows, I have a problem with a 2 node RHCS cluster (CentOS 4) where node 1 failed and node 2 became active. That happened already last year and due to holidays the customer didn't recognize it. The cluster is just a failover for Apache and has no shared storage space. Customer now saw the situation, tried to fix it by rebooting node 1, which then failed to come back up. As service ccsd started but couldn't get full cluster information the followup service cman hangs forever - bootup hangs in this state. Omitting cluster service starts at boot time by being selective (boot parameter confirm) brings up the box. ccsd starts up (by service or by hand and with parameter -n), but syslogs that it fails to get cluster infrastructure information. So the cluster is in inquorate state. Anyone experienced with the RHCS knows whether I can avoid switching down node 2 and the Apache service for which the cluster runs? Documentation (manual and FAQ) is silent about this. I verified that there is no network / NIC problem. How to get the 2 node cluster back into quorate state? Thanks for helping. Cheers Alexander

VMWare GSX Server and CentOS
by Joshua Gimer 15 Jan '07

15 Jan '07

Has anyone had experience (good or bad) with VMWare GSX Server running CentOS as a VM under high load? Here is the situation. We are planning on rolling out some new boxes to replace an existing box. Currently this box (Sun V860) is running web services, database services, mail for students, and is an instructional box for compiling code, and web scripting among other things. We are planning on doing one of two things, either using VMWare and splitting up the services or using Solaris Zones. The box(s) has to be able to access data stored on the SAN (Fiber Channel HBA's). The boxes(VM's), or Zones would be split up accordingly: Database box: Oracle, Postgres, and MySQL Mail: Sendmail, POPS, and IMAPS (roughly 25,000 mailboxes) Web: Apache, PHP, mod_ssl Interactive Logins: Compilers and such. Any information about any experiences with VMWare and CentOS, under similar load would be helpful. I will probably make this same post on the Sun Solaris Mailing List, and VMWare's forums. Thanks in advance! -- Thx Joshua Gimer

Gnome-terminal $PATH
by Jordi Espasa Clofent 14 Jan '07

14 Jan '07

Hi all, Usually I work in X environment (XCFE) with extensive use of x terminal; concretely, I use Gnome-terminal. Sometimes I change to root to do some admin tasks. But often it seems a few commands are not availables. The key is in the $PATH value: echo $PATH (in login shell, interactive ): /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/local/sbin:/sbin:/bin:/usr/bin:/usr/sbin:/usr/X11R6/bin:/root/bin echo $PATH (in gnome-terminal, no-login interactive shell): /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/jordi/bin The last path in $PATH variable shows me that the problem would be the gnome-terminal doesn't update correclty the $PATH when I change to root through "su" command. ¿What do you think about? TIA.
