What I would love to find a way to do is this: yum --disablerepo=* --enablerepo=csgfs update ...and still allow yum to use the base and update repos to satisfy dependencies. What I did instead was this: yum --disablerepo=* --enablerepo=csgfs check-update I then grabbed the list, extracted the package names and fed them back to "yum update". The idea was that I wanted to update the csgfs packages and the required kernel (and other) packages, but I wanted to hold off on the rest of the 4.3 updates. -- Bowie

device-mapper multipath
by Eric Lee 13 Apr '06

13 Apr '06

I am attempting to get multipath working with device-mapper (CentOS 4.2 and 4.3). It works on EVERY install of mine from RH (also v4.2, 4.3), but the same multipath.conf imported to all my installs of CentOS do not work. Note that I have tested a working 4.2 configuration file from RH on CentOS 4.2 and a working 4.3 configuration (it changed slightly) on CentOS 4.3. Neither worked. Our production systems are RH 4.2 so the 4.2 configuration file is below. Configuration: Promise vTrak 300i iSCSI iscsi-initiator-utils from 4.2/4.3 device-mapper-multipath from 4.2/4.3 Procedure: 1. Configure iscsi.conf and multipath.conf 2. Start iscsi: service iscsi start 3. Start multipath: service multipathd start 4. Make sure no stale paths exist: multipath -F 5.

Update of CentOS 4.0 to 4.3
by Barry Brimer 13 Apr '06

13 Apr '06

I need to update a CentOS 4.0 system to CentOS 4.3. In my opinion, I should start out with a "yum update yum centos-yumconf" and then follow that with a "yum update". Does anyone have any other input as to what other packages might be needed to be updated with yum and centos-yumconf before the mass upgrade? Thanks, Barry

apache permission problems
by Nick Smith 13 Apr '06

13 Apr '06

Well i finally got CentOS 4.3 booting, apache is installed, and im trying to setup some virutal hosts, i want the main site to be my default virtual host (which i had on my gentoo server) but i keep getting permission denied errors: Forbidden You don't have permission to access / on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. and in the logs i get: (13)Permission denied: access to /favicon.ico denied (13)Permission denied: access to /favicon.ico denied (13)Permission denied: access to / denied i have even tried chmod 777 on the /home/user/public_html dir and that still didnt resovle the issue. What user do the files have to be owned by? i would assume the user, but i have also tried apache:apache and root:root, since the original htdocs dir was owned by root:root. everything ive tried just gives me the same permission denied error. here is my vhosts.conf file (i created it under conf.d) NameVirtualHost *:80 <VirtualHost *:80> ServerAdmin webmaster(a)domain.com ServerName domain.com ServerAlias www.domain.com DocumentRoot /home/nick/public_html ErrorLog /home/nick/logs/error_log CustomLog /home/nick/logs/access_log combined <Directory "/home/nick/public_html"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> </VirtualHost> It DID work with the default install, i got the default page, but for some reason when i switch to virtual hosts i started getting denied. I also have this in my httpd.conf file: <IfModule mod_userdir.c> UserDir public_html # # Control access to UserDir directories. The following is an example # for a site where these directories are restricted to read-only. # <Directory /home/*/public_html> AllowOverride FileInfo AuthConfig Limit Indexes Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec <Limit GET POST OPTIONS PROPFIND> Order allow,deny Allow from all </Limit> <LimitExcept GET POST OPTIONS PROPFIND> Order deny,allow Deny from all </LimitExcept> </Directory> <Directory /home/*/public_html/cgi-bin> Options ExecCGI SetHandler cgi-script </Directory> </IfModule> any ideas? any other info you need to help me out? thanks Nick

horde updates and config files

Horde RPMs got updated last night. However, the way configuration files were handled wasn't probably the best.

Building external modules on 4.3
by James Fidell 13 Apr '06

13 Apr '06

I'm trying to build the zaptel (v1.2.5) modules on a 4.2 machine upgraded to 4.3, but running into a kernel version problem. The kernel I'm running is 2.6.9-34.ELsmp and I have the kernel-devel-2.6.9-34 RPM installed. I believe the problem is that the modules are being built as if for the uniprocessor kernel (the default for kernel-devel?) leading to the error: zaptel: disagrees about version of symbol struct_module when I try to load the module. I *think* I probably need to grab the kernel sources, take the config file for the SMP kernel from that and drop it into kernel-devel, edit the kernel-devel top-level makefile to get the version name correct and then rebuild the kernel config to get the right kernel version set in the zaptel modules. Is that correct, or have I missed something obvious? James

Multiple LUN support
by Mark Elam 13 Apr '06

13 Apr '06

Hi all... I have a scsi Tape library. Centos only sees the tape drive portion of the library. I need to enable Multiple LUN support to get the library and tape drive recognized. I am looking for some help enabling multiple lun support in Centos 4. I had a procedure on how to do this in the 2.4 kernel but it doesn't seem to work in the 2.6. Any help would be appreciated. Config: Standard intel server board. p4 processor (3) 3-ware controllers Lsi Logic u320 scsi card External SCSI tape library. Worked before on a Whitebox linux 2.4 kernel, just added: options scsi_mod "max_scsi_luns=16" to /etc/modules.conf and rebuilt the initrd image, then reboot. All worked fine. But Whitebox is crap and was giving me probs and also want everything standardized on CentOS! Thanks!

Robust Search Solution (with CentOS 4.3)
by Mike Stankovic 13 Apr '06

13 Apr '06

I've got about 10,000 docs I'd like to devise a search/index for. I found a perl script called Perlfect that can do that on an old P3 but at the astronomical time of 7 hours. Another script(cgi/perl) at hotscripts can do the same but allows the "rm -rf /" exploit. DoH!? Is there anything perl/flatfile that can search/index faster? This is a nice job for an aging P3 in the corner so php/MySQL is not an option. Don't suggest beagle/windows solutions as this is a CentOS 4.3 system. __________________________________________________ Improve the mailing list by performing a simple search before posting and reading the faq/etiquette.

Centos 4.x, gnome & key "repeating"
by Finnur Örn Guðmundsson 13 Apr '06

13 Apr '06

Hi, I have a strange problem with Centos 4 (all kernels so far). When i am running gnome (havent tried KDE) and i go into a browser or even just a console window and type something a letter repeates it self 10-20 times (likeeeeee thhhhhhissssss). I can turn this of the the keyboard settings (repeating keys) but then i cant hold down backspace and so on ....I think this is some kind of software error but cant really figure it out :| My hardware is: Nvidia NFORCE4 chipset AMD X2 4200+ 2Gb Memory SATA harddrive SMP kernel (all of the Centos kernels seem to have this problem...havent tried the uni processor onces tho) I've also ran Fedora Core 4 & Fedora Core 5 on this box and have no problems there. Anyone knows a solution for this (except for turning off Repat Keys). Thanks, Finnur Guðmundsson

kernel: Page has mapping still set - continues
by Alan Sparks 12 Apr '06

12 Apr '06

Been having this problem, and posted about it before. Thinking it was a memory issue, I've replaced all memory on the server. However, the problem has continued. Server is a Proliant DL380 (8GB RAM, 2 Xeon CPU), running CentOS 3.6, all patches up-to-date. Kernel is 2.4.21-40.ELsmp (problem seems to have first manifested on kernel 2.4.21-37.0.1.ELsmp). Disk is CCISS hardware RAID-5, straight partitioning (no LVM). This server runs an Oracle 10g instance, async I/O enabled to a NetApp filer where most data is stored. Traceback of latest failure follows (two crashes this morning). Anyone read these things well enough to tell me if there's any insight in this? There are no nVidia drivers loaded, only stock kernel modules. Thanks in advance for any insight. -Alan Apr 10 05:32:22 db01-01 kernel: page not mapped. erroring out.

bootup error - undefined symbol: lvm_snprintf after yum update
by Bowie Bailey 12 Apr '06

12 Apr '06

This is an x86_64 system that I just updated from 4.2 to 4.3 (including the csgfs stuff). When I watch the bootup on the console, I see an error: lvm.static: symbol lookup error: /usr/lib64/liblvm2clusterlock.so: undefined symbol: lvm_snprintf This error comes immediately after the "Activating VGs" line, so it appears to be triggered by the vgchange command in the clvmd startup file. I have another, identically configured, server which I have not updated yet. This server does not give this error. Everything seems to be working fine, so is this something I need to worry about? -- Bowie

crond not starting on reboot since U7
by Ugo Bellavance 12 Apr '06

12 Apr '06

Hi, Just updated a few servers to U7, and rebooted them. I found out that crond would not start at boot even if it is configured to: crond 0:off 1:off 2:on 3:on 4:on 5:on 6:off I have tested another reboot, same thing: I had to start crond manually. I don't see anything in the logs, and I don't have direct access to the console right now. Anyone seen the same thing?

mediawiki-1.4.7-1.2.el4.rf.i386.rpm requirements.
by Will McDonald 12 Apr '06

12 Apr '06

Guys, I'm migrating an internal Mediawiki over to a new CentOS 4 system. The old server's running FC3 and has a tarball install, ideally I want to stick to properly packaged software as far as possible. [wmcdonald@willspc ~]$ yum deplist mediawiki Finding dependencies: Setting up repositories Reading repository metadata in from local files package: mediawiki.i386 1.4.7-1.2.el4.rf dependency: tetex-latex provider: tetex-latex.i386 2.0.2-22.EL4.7 dependency: tetex-dvips provider: tetex-dvips.i386 2.0.2-22.EL4.7 dependency: ImageMagick provider: ImageMagick.i386 6.0.7.1-14 dependency: mysql-server >= 3.2.0 provider: mysql-server.i386 4.1.12-3.RHEL4.1 dependency: php >= 4.3.11 Unsatisfied dependency Looking at the RPMForge mediawiki package, it requires php >= 4.3.11 which isn't available either from RPMForge or CentOS 4 base. php-4.3.9-3.9 seems to be the latest. What's the best way to proceed here then? I noticed there are PHP5 packages in the centosplus repo, but those wouldn't be available to an RHEL system. Will.

I'am running CentOS 4.3 on an (Intel) with one SATA disk (/dev/sda). The output of fdisk -l: Disk /dev/sda: 81.9 GB, 81964302336 bytes 255 heads, 63 sectors/track, 9964 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 19 152586 83 Linux /dev/sda2 20 2569 20482875 83 Linux /dev/sda3 2570 2700 1052257+ 82 Linux swap /dev/sda4 2701 9964 58348080 5 Extended /dev/sda5 2701 9964 58348048+ 83 Linux So, I have an identical second disk (sdb) connected...

Multiple ISPs
by Neil Jolly 12 Apr '06

12 Apr '06

I have a situation where I need, what I'll call, a high availability router to provide fail over between a cable service, and adsl service, from 2 separate ISPs. There is no requirement for outside access just high uptime requirements for internet access from the lan to the internet. At present I'm looking at just running a perl, or shell, script to ping the gateway and then fail over to the opposite interface, and vice-versa. Anybody know of a better way to do this, or have any experience with a similar situation? Thanks, Neil Jolly

Thanks for the help guys. To resize my screen I had to go through the GUI part and change it but unlike Microsoft it makes me reboot in order for it to take affect which sucks. The Ctrl Alt +/- does not work. As for adding a printer someone finally gave me the link to the correct document which showed how to do it. I received a link where you can download the CentOS manual in PDF format: http://www.centos.org/docs/4/pdf/ but the guy didn't tell me which manual I'm suppose to download. I cant tell what's what by the name so unless someone here can point me in the right directions I'm still waiting on their response.

SMP kernel on old Asus CUV4X-DLS motherboard
by Aleksandar Milivojevic 11 Apr '06

11 Apr '06

Just wondering if anybody managed to get SMP kernel to boot properly on an old Asus CUV4X-DLS motherboard (older dual P-III)? I had this problem only with this specific motherboard and 2.6 kernels. First time couple of years ago. And again today (I've just installed CentOS4 on a box that used to run RH7.3). Previously those machines were running Red Hat 7.3 (2.4 kernels), and with 2.4 SMP kernel all worked fine. The issue I'm having is that when device driver modules are loaded from initrd's init script, insmod doesn't wait until each driver it loads is completely loaded and initialized. It just exits with right away and init script goes on and starts loading next device driver. It looks like bang, system loads all of them in parallel. Of course, this doesn't work really well. Before RAID and SCSI drivers have time to scan the bus and detect disk drives, vgscan is already done, and of course it doesn't find any volume groups, since previous device drivers haven't yet detected any drives. All I can see on console is interleaved messages from various device drivers intializing with messages from LVM, followed by kernel panic because it couldn't mount root file system. All completely out of order. The output on console looks something like this: Loading scsi_mod.ko module Loading sd_mod.ko module Loading 3w-xxxx.ko module Loading scsi_transport_spi.ko module Loading sym53c8xx.ko module Loading dm-mod.ko module Loading jbd.ko module Loading ext3.ko module Loading dm-mirror.ko module Loading dm-zero.ko module Loading dm-snapshot.ko module Here goes output from loaded modules, in no particular order, all totally mixed up, couple of lines from 3w-xxxx, then couple of lines from sym53c8xx, then couple of lines from 3w-xxxx again and so on... By the time vgscan is run, even the jbd and ext3 modules are not yet completely loaded in kernel. If I boot single processor kernel, all is fine. Device drivers are loaded one by one, insmod waits for device driver to initialize properly. Just as it should be. The output on console looks like: Loading scsi_mod.ko module Loading sd_mod.ko module Loading 3w-xxxx.ko module Otuput of 3w-xxxx detecting RAID volumes Loading scsi_transport_spi.ko module Loading sym53c8xx.ko module Output of sym53c8xx detecting SCSI devices Loading dm-mod.ko module Loading jbd.ko module Loading ext3.ko module Loading dm-mirror.ko module Loading dm-zero.ko module Loading dm-snapshot.ko module The workaround I have to get system to boot using SMP kernel is to modify init script from initrd, and insert bunch of sleeps after each insmod to give device driver ehough time to initialize before next device driver (wich might depend on one or more previous device drivers) is loaded. This kind of works, but it's just an ugly hack to hide underlying problem. Of course, there is also this nasty feeling that something inside kernel doesn't really work well and that other things might break or that data might get corrupted. When I was Googling around, I also found suggestion to turn off MPS 1.4 in BIOS, but it made no difference in my case. Of course, turning ACPI off can't be done on SMP kernel (and system works fine with ACPI using single-processor kernel). I'm still not sure if this is problem with kernel (things worked fine with 2.4 SMP kernels), or some strange bug in (new) insmod executable that surfaces only when using this particular motherboard. Anyhow, to conclude this lenghty email... Any success/failure story with running 2.6 SMP kernel based distro (particuallary CentOS4) on this motherboard is more than welcome. -- See Ya' later, alligator! http://www.8-P.ca/

What's going on here? Should I force the upgrade in this case, or is there a better solution? -- Bowie

SATA Raid 5 and losing a drive
by Andy Green 11 Apr '06

11 Apr '06

Hi Folks - Using CentOS on a server destined to have a dozen SATA drives in it. The server is fine, raid 5 is set up on groups of 4 SATA drives. Today we decide to disconnect one SATA drive to simulate a failure. The box trucked on fine... a little too fine. We waited some minutes but no problem was visible in /proc/mdstat or in /var/log/messages or on the console. I ran mdadm --monitor /dev/md0 and no problem was shown. We rebooted still without the drive and finally mdadm --monitor reported that the array was running in a degraded state. We reconnected the SATA drive and still nothing was reported and nothing happened with the raid state according to /proc/mdstat. I expected the box to keep on trucking but to become freaked out with warnings all over the shop. What should I have expected in this case and what should I do to become aware of evil events like the drive melting remotely? -Andy

Postfix on VLANs
by Andrew Vong 11 Apr '06

11 Apr '06

Hi All, I'm having some problems getting postfix to relay mail. I'd appreciate any tips. Perhaps there are some settings which I may have missed, somewhere. The postfix mail server is on VLAN 250 (192.168.250.0) whilst I have several other users on other VLANs (e.g. 91, 92, 93, etc... 192.168.91.0, 192.168.92.0, 192.168.93.0, etc...). So, if I had a PC sitting on VLAN 91 with IP 192.168.91.1, I am unable to relay mail BUT checking mail via POP3 works fine. In /etc/postfix/main.cf, I have set the following:- mynetworks_style = subnet mynetworks = 168.168.91.0/28, 127.0.0.0/8 Do you know what setting I may be missing? Thanks. Best Regards, Andrew

I can see the aacraid module in the list but as soon as I choose it. Then I get a screen saying "Do you wish to load more Driver Disks?" I can see in the logging that it can't find the driver it also gives a "Can't find a valid FAT filesystem on dev fd0". I have dd'ed the image ... it is a ext2 Filesystem and used RAWRITE. Is there more that I can try ? Any Suggestions ? Thanks Karl -- ----------------------------------------- Karl Fischer Drone, Human and Gnome User I support 10x10.

Or anyone knows of another graphical ACL editor with more conservative dependancies. Thanks Yanik

yum repository conflict resolutions
by Dave 11 Apr '06

11 Apr '06

Hello, I'm setting up a test mailserver on centos4. I want to use stable rpm packages but ones that don't have conflicting lib requirements. I've got the standard yum configuration with one excdeption i've enabled the centosplus yum repository. I've read that dag's repository has a package i'm going to need courier so i figured to set that up. Here's my problem, if i then do a yum update on this box and more than one repository has a package say kernel which does it get? Or, if a package has a library dependency and that is installed and it conflicts with another, how would this be resolved? Sorry about the confusion any help appreciated. I'm also going to possibly have a need to roll out custom-made rpms not sure yet on that one, and it's been a while since i did them, rh7 i think was the last time. Does anyone have a Centos-specific howto on this not for modifying an existing srpm, but for creating an rpm from tarball? Thanks. Dave.

redirecting some addresses with sendmail
by Tony 11 Apr '06

11 Apr '06

I have a fully working cyrus+sendmail mail server hosting all users for foo.com. Company foo has been acquired by company bar and it has been decided that bar.com is the new domain of choice. The administrator of bar.com has added a pile of redirects to send various user(a)bar.com addresses so they come up to my server at foo.com. My users have changed their From: addresses to user(a)bar.com and we have a basic working system. However, if one user in former company foo mails another user in the same office their mail now goes offsite to bar.com's mail server and is then redirected back in again, which works but is bad for bandwidth. Ideally I'd like to teach sendmail that a subset of bar.com users are now local. However if I try this in the /etc/aliases file, I get the warning "cannot alias non-local names". Has anyone got any better ideas how to do this- or a better suggestion as to where I should ask this question again? -- Cheers, Tony

athlon64/opteron 8GB per CPU
by David Thompson 10 Apr '06

10 Apr '06

I'm putting together a spec for a big(ger) memory x86_64 host, and I hope some of you-all can help. I'm looking for success stories of hardware that folks are using in production environments, preferably with CentOS 4, with more than 4GB of memory per CPU. I know there are lots of mobos out there that can do this, but I'm looking for what folks really have running. Call me paranoid. The target is SATA + n*GigE + 1CPU + 8GB memory, and I can consider other configurations. The incumbent system is a Xeon 8GB system running i686 CentOS 4.3 (what else?), with light CPU loading and very heavy IO loading (WD raptors are our friends). Folks with deep(er) knowledge of x86_64 architecture, I'd also be interested in the trade offs between 1CPU w/8GB and 2CPUs each with 4GB. (E.g. what's the real cost of shipping data back and forth between the memory spaces of the two CPUs? How does the 2.6 kernel deal with the split memory space? etc...) The memory is all going to be used up in kernel buffers keeping bits of files in kernel memory. Also, trade offs between Opteron and Xeon architectures, i686 vs. x86_64, bounce buffers, etc., for an application like this would be helpful. The application is enhancement to a mirror server (mirror.cs.wisc.edu) here at UW-Madison. Many thanks to all in advance. Private or public replies welcome. Dave Thompson UW-Madison

What speed will the network be running at? The traffic is rsync (out; we have another box that grabs content for us), http, and ftp. It's all GigE locally, and BIG pipes to the internet. Before linux distros exploded in size and number, we pushed several hundred gigabit for several days when someone did a release. Dave

Looking at their web site, it's like they have disavowed any knowledge of having built anything Opteron. Did they back out of Opteron, or do you have to be a member of a secret society to get to their information? >One caveat with these Supermicro boards is the the onboard SATA (some >sort of Adapted branded Marvell thingy) isn't supported.

The newer SM boards have HT2000/HT1000 based SATA which centos 4.3 >should support, but I've no experience with 'em. Yeah, I've been there also. We also use alot of threeware in these applications. The other add-in sata that I've used in 3112, but that hasn't always worked. >I don't know how deep my knowledge is, but we run a lot of memory >intensive code on these nodes and get a 2X speedup with dual CPUs.

But the CPUs aren't going to be loaded (at all), so I'm concerned of hurting throughput by splitting the memory space. Tyan is working on a mobo with 8 slots per CPU (S3892), but my favorite vendors aren't carrying it (yet). Dave

P3Scan support
by Jens Abraham 10 Apr '06

10 Apr '06

Hello, I want to ask if CentOS will support P3Scan (http://p3scan.sourceforge.net/) as RPM delivered with the distribution? For explanation: P3Scan is an transparent mailproxy. It uses ClamAV and SpamAssassin to distinguish between Spam- Virus- and normal Mail. Its more usefull to get an update via the repos instead of compiling it by myself. I hope you understand my englisch. ;) Greets Jens -- http://core.pnode.de/wordpress/ - Core Blog (offline) "Bis zum Meer für einen Bruder, durch das Meer für eine Geliebte" -Bulgarisches Sprichwort Echte DSL-Flatrate dauerhaft für 0,- Euro*!

Network and default route
by Scott Silva 10 Apr '06

10 Apr '06

I have had this problem on and off since RedHat 6, and I always worked through it, but I thought I would ask. When you have multiple network interfaces, how does the system determine the default route? Or is it the first, (or last) interface that comes up? On the problem systems I have to add a "route add default..." statement in some systems in the rc.local to get them to work right. -- MailScanner is like deodorant... You hope everybody uses it, and you notice quickly if they don't!!!!
