Intel i7-940, DX58S0 motherboard, Radeon X1950 Pro video card
by Frank Cox 20 Nov '09

20 Nov '09

This computer is my main desktop machine --- an Intel i7-940 CPU and DX58S0 motherboard with a Radeon X1950 Pro video card. It's currently running Fedora 11 and working just fine. However, I have been slowly moving all of my "computer stuff" off of Fedora and onto Centos, and this (and my Acer Aspire One laptop) are the only Fedora installations that I now have left. Does anyone have any experience with this CPU, motherboard and video card on Centos? This hardware (sound, video, ethernet, what-have-you) works fine on Fedora 11; can I expect it to also work fine with Centos 5.4? The ethernet isn't a big deal because I can easily slap another network card into it, but the rest isn't quite so easy to substitute. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

kdump location recommendations?
by Florin Andrei 20 Nov '09

20 Nov '09

I need to make a decision on the configuration of the kdump location for a bunch of new machines. It seems like using a raw partition directly is the safest choice, right? If I configure it to dump vmcore on a filesystem, and the filesystem gets corrupted somehow, then the dump will fail. Same for network-based dumps (the remote end may be unavailable due to a number of reasons). The local storage is a couple SATA drives with hardware-based mirror RAID. The chassis is a Dell PowerEdge. Also, what it the recommended size for a dedicated raw partition for kdump? -- Florin Andrei http://florin.myip.org

Problem with Samba on CentOS 5.3
by Kaplan, Andrew H. 20 Nov '09

20 Nov '09

Hi there -- I am having an issue with the Samba package, release 3.033375, that came bundled with the CentOS 5.3 distribution. It seems that even though I created the smbpasswd file, located at the /etc/samba directory, I am unable to modify the password of the users listed in it. I can run the /usr/bin/smbpasswd -a <username> command as root, and even though there are no errors, a subsequent check of the smbpasswd file indicates the username in question is still listed with the series of X's and NO PASSWORD indicator. I have confirmed through the find command the only instances of smbpasswd are those at the /etc/samba and /usr/bin locations. Has anyone seen this issue, and aside from installing samba from source, have a solution to this problem? Thanks.

CentOS-DS Configuration/Setup Issue

20 Nov '09

All, I'm running CentOS 5.4 and I've installed the CentOS Directory Server by running yum -y install centos-ds* without any errors. But as soon as I attempt to run the setup I get the following: [root@jpdsys3 ~]# /usr/sbin/setup-ds-admin.pl Can't locate Setup.pm in @INC (@INC contains: /usr/lib64/dirsrv/perl /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at /usr/sbin/setup-ds-admin.pl line 24.

High load averages with latest kernel and USB drives?
by Benjamin Smith 20 Nov '09

20 Nov '09

I'm having a server report a high load average when backing up Postgres database files to an external USB drive. This is driving my loadbalancers all out of kilter and causing a large volume of network monitor alerts. I have a 1TB USB drive plugged into a USB2 port that I use to back up the production drives (which are SCSI). It's working fine, but while doing backups (hourly) the load average on the server shoots up from the normal 0.5 - 1.5 or so up to a high between 10 and 30. Strangely, even though the "load is high" the server is completely responsive, even the USB drives being accessed are! Backup script is really simple, run via cron, pretty much just: #! /bin/sh hour=`date +%k`; pg_dump <options> mydatabase > /media/backups/mydatabase.$hour.pgsql; where /media/backups is the mount point for the USB drive. Using top to diagnose, nothing seems to be particularly high! IoWait seems reasonable (10-30%) and CPUs are 0.5%, Idle is 70-90%. Even accessing the USB partition while the load is "high" is responsive! I'm guessing that something changed in how load average is counted? Server Stats: Late model 8-way Xeon, SuperMicro brand. CentOS 4.x / 64 (all updates applied, booted after last kernel update) Kernel 2.6.9-89.0.16.ELsmp 4 GB ECC RAM 300 GB SCSI HDD. Standard Apache/PHP, Postgres 8.4. Any idea how to revert to the old load average tracking behavior short of using a stale and potentially insecure kernel? -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Why swap if there's still physical memory available
by yanagik317 19 Nov '09

19 Nov '09

Dear CentOS people, This is just a general question related to memory management, and there may have been a thread or two about it before, but I'd like to post anyway. A user was looking at top, whereby he found out that his two processes were 10.2g and 4836m in VIRT. They were 6.4g and 4.6g in RES respectively. 3445964k was free still. He was wondering why the system didn't use all of the physical memory available (16300960k total) before swapping out parts of the processes. Over time, the 10.2g process had about 8g of it in SWAP. The 4836m process only had about 100m in SWAP. Much of the physical space is now used. I guess the answer may not be that simple and I most likely haven't described everything that could have influenced the kernel's decision-making, but how does Linux decide how much of a process to be swapped out? I guess I could read the documentations on the Linux kernel, but does anyone have more general answers ready to be dispensed? I haven't done anything with sysctl, if that comes into play at all. Thank you, --Koji

serial console config package?
by Jiann-Ming Su 19 Nov '09

19 Nov '09

I've been installing CentOS via PXE and using a serial console interface. The installation works great. I notice that during the install process, the following line gets added automatically to /etc/inittab: co:2345:respawn:/sbin/agetty ttyS0 9600 vt100-nav Which package does this? Is it kudzu? Thanks for any insights. -- Jiann-Ming Su "I have to decide between two equally frightening options. If I wanted to do that, I'd vote." --Duckman "The system's broke, Hank.

stupid Centos-DS questions
by Alan McKay 19 Nov '09

19 Nov '09

OK, I'm mostly through everything up to and including Chapter 5 in http://www.redhat.com/docs/manuals/dir-server/8.1/install/Installation_Guid… And looking through the ToC for the rest, I do not see that my questions will be answered by this doc. So please feel free to point me to other docs. This manual seems to assuming I already know what it is I want to do, and what "Directory Services" are all about. Invalid assumption. For example, right now I am reading about how to set up different instances of this-or-that (Admin Server, Directory Server, yadda, yadda). What it does not tell me is why I would want to do that. It does not even tell me "what is an 'instance'" . I've never done any sort of DS, so this is all new stuff to me. Suggested reading is very welcomed. What is even more welcome is pointers to case studies or template examples. We are a very small company with only about 30 people right now. Though we do have a convoluted network with 3 distinct network areas separated by VPNs. I'm new here (and put in charge), and we are not even running DNS yet (eeep! for REALZ!!!). To me it makes sense to have 3 different DNS subdomains because of some quirks they have in their product architecture here. I'm thinking "office.example.dom", "production.example.com" and "rc.example.com". And from the bit I've read so far on DS, it seems to be recommended to have your DS mirror your DNS. So we are small enough where I do not think we need more than 1 server to run it all. And I can make all the machines talk to that server through the firewalls separating the 3 zones. That is not an issue at all. I'm not sure how this affects my DS. Would these be "instances"? So many questions ... please suggest reading material. thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

New install RAID 1+0
by Craig White 19 Nov '09

19 Nov '09

I have a new server to setup. 4 hard drives and I had intended it to be hardware raid but that's a long story. Does it make sense to set up the first two hard drives with RAID-0 partitions and then get through the install and then go back later and then create identically sized RAID-0 partitions on the other two drives and finally create the RAID-1 mirror from the first to the second?

my local mirror stopped working
by Alan McKay 19 Nov '09

19 Nov '09

Hey folks, I've had a local mirror set up for some time now and it has always worked, but suddently stopped. I don't think the fact that it stopped work has anything to do with when I blew away that machine and changed it from Centos 5.3 to a Fedora Core 11 box. But I'm not sure how that could make any difference since it is just serving that stuff over the web. It still works great for Kickstart installs. I still have a nightly cron job to update from my closest mirror thusly : rsync -avSHP --delete --exclude "local*" --exclude "isos" rsync://mirror.csclub.uwaterloo.ca/centos/5.3/ /var/www/html/ks/centos/5.3/ Here is the error I get when trying to run yum now. Note that I check for the file it is complaining about and it exists but is .gz format and not .bz2. I guess I could gunzip then bzip to fix the problem? But I'd really like to understand why this started. http://yum/ks/centos/5/updates/x86_64/repodata/filelists.sqlite.bz2: [Errno 14] HTTP Error 404: Not Found Trying other mirror. Error: failure: repodata/filelists.sqlite.bz2 from updates: [Errno 256] No more mirrors to try. As I've reported before to the list, here is how I've set it up : * On my PC I've created /var/www/html/ks for doing kickstart installs, and it shows up at http://192.168.0.222/ks/ * the Centos 5.3 DVDs got downloaded - both 32 bit and 64 bit mkdir /mnt/C5.3_{32,64} chmod 0777 /mnt/C5.3_{32,64} mount -ro loop /home/amckay/Desktop/CentOS-5.3-i386-bin-DVD.iso /mnt/C5.3_32 mount -ro loop /home/amckay/Desktop/CentOS-5.3-x86_64-bin-DVD.iso /mnt/C5.3_64 mkdir -p /var/www/html/ks/centos/5.3/{os,updates}/{i386,x86_64} pushd /var/www/html/ks/centos/ ln -s 5.3 5 popd rsync -avHPS /mnt/C5.3_64/ /var/www/html/ks/centos/5.3/os/x86_64/ rsync -avHPS /mnt/C5.3_32/ /var/www/html/ks/centos/5.3/os/i386/ rsync -avSHP --delete --exclude "local*" --exclude "isos" rsync://mirror.csclub.uwaterloo.ca/centos/5.3/ /var/www/html/ks/centos/5.3/ chown -R apache:apache /var/www/html/ks/ And when I do a Kickstart install, it works just fine. AFter the install in the %post I change the Centos-Base.repo to point to my local repo thus : [base] name=CentOS-$releasever - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os baseurl=http://yum/ks/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 #released updates [updates] name=CentOS-$releasever - Updates #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates baseurl=http://yum/ks/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 Note that the name "yum" does properly resolve to my box. -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

php config security concern for c5
by Joe Pruett 18 Nov '09

18 Nov '09

a recent post on bugtraq hilighted an issue with how upstream has configured apache to invoke php, namely using addhandler, which has the behavior of matching the extension anywhere in the file. this means that foo.php.jpg will be run as php. where this becomes an issue is web apps that allow uploads into the webspace for images, pdfs, etc. if the app assumes that anything.jpg is safe, this addhandler feature will surprise it. a fix is to replace two lines in /etc/httpd/conf.d/php.conf: AddHandler php5-script .php AddType text/html .php with: <FilesMatch \.php$> SetHandler php5-script ForceType text/html </FilesMatch> i have reported this upstream. hopefully they will see it as a problem and address it.

Well, there's a bug in the globbing for the tcsh with 5.4, and my boss has filed a bug report. Meanwhile, I downgraded tcsh on those systems whose users use that as their shell. Until it's resolved, he wants me to pin the version. Googling, I see someone a few years ago, answering someone's question, suggested adding exclude=openoffice* near the top of /etc/yum.conf. I also see, more recently, several additional yum-related rpms, such as yum-versionlock. Will the first solution work (editing yum.conf), and, if so, for tcsh, would I need the asterisk, or would exclude=tcsh work? Alternatively, is that deprecated, and if so, which additional yum-related package is recommended for this? mark

OT: Using rdesktop as terminal client to Windows 2008 R2
by carlopmart 18 Nov '09

18 Nov '09

Hi all, I am using rdesktop as a terminal client to connect to Windows Terminal Server over years without problems until now. I have a problems with five Windows 2008 R2 servers: point cursor turns black when I connect to them. But this problem disappears if I turn on windows 7 theme on these servers, but performance it is very very bad. This problem only appears with windows 2008 R2 and not on Windows 2008 SP2 or Windows 2003 R2 servers. I have tried to add: Option "SWcursor" "true" (nvidia graphics card using native nvidia drivers), on my xorg.conf without luck. My laptop is centOS 5.4 fully updated with rdesktop-1.6.0-3. Any ideas?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

Removing respawning process from inittab w/o killing it
by Timo Schoeler 18 Nov '09

18 Nov '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I need to remove an entry of inittab which is used to (re)spawn a process: mydemon:2345:respawn:/usr/sbin/mydemon >/dev/null 2>&1 So, I would comment out that entry and reload init running ``telinit q''. IIRC, this would lead to the currently running daemon being killed. I don't want to /try/ whether I'm right, as those are production systems. Is there any possibility (given that ``telinit q'' kills the running process) to 'keep the process alive' _and_ reload init?

openvpn server: one client works; one fails.
by Mike - email ignored 18 Nov '09

18 Nov '09

I installed an openvpn-2.0.9 server on my new CentOS 5.4 box from using the same parameters I used on a Fedora box I retired. Now I have a dual boot laptop that has WinXP and Fedora FC8. Both of these partitions have openvpn clients installed that have worked well in the past. After adjusting these for new IP addresses, I find: WinXP: connects and contacts boxes on the same LAN as the server. FC8 appears to connect but will not contact anything. Since I have nested routers, I was able to disconnect from the real WAN, and use an emulated WAN. I then shut off iptables on both Linux boxes. The behavior was not altered. BTW, I use TAP rather than TUN. I have run out of ideas. Suggestions would be most welcome. Thanks, Mike.

Keeping iptables in sync across multiple machines
by Karanbir Singh 17 Nov '09

17 Nov '09

hi, Just wondering what people use / recommend to keep multiple machines in sync with their iptables policy. What I use at the moment: 1) Puppet, to setup and manage a fairly complex per service type ruleset that is then maintained on the remote machines by puppet ( in that it brings together all the various bits of iptables snippets based on what manifests and roles are deployed to a machine, then builds a firewall locally on the mchine ). We also use something similar, but at a much simpler level within the .centos.org infrastructure. Problem with this is that unless one is familliar with the whole stack of machine state/policy management, its quite intimidating. Which then means that there is plenty of breakage, which in turn then means I need to maintain and run a complete set of VM's that emulate the production environment ( including their IP's ) and run cross VM tests before stuff gets rolled out. So yes, large hole and lots of potential for non-related issues to impact release. Some people even argue that having a release based workflow for firewall's is not good, I'd like to disagree :) 2) In another setup, I use puppet to basically just manage static /etc/sysconfig/iptables files. Pretty low tech, and very easy to cause damage since testing-rollout-deploy is impossible. But the other guy who also needs to manage these seems to find it easy. 3) Yet another setup I've used in the past was with a svn repo and using a post-commit hook, run some tests followed by clusterssh! to deploy the iptables files and restart services. Finally replaced that with a slack based deployment, since that allowed me to atleast run some santity tesing and rollback if I ended up locking 'core' host. The problem ofcourse was that its not easy to test remote inbound connections this way ( without using a proxy, but then the proxy creates another layer of problems and flakyness ). 4) Physically logging into machines to make policy changes(!) I do this for my laptop's :) 5) Using a 'git pull' from cron on a bunch of machines, and using a central git repository. Each machine would then do a iptables reload, the only advantage of this over (3) is that I can use metainfo like TAG's and ROLE's in the commit log's, and have only specific machines react to specific changes. Flip side: needing to track and build a knowledgebase around these TAG's meant that I almost never ever use this, and prefer to just have firewall policy that mostly works for the whole set of machines I run this on. So, what I am looking for really is feedback on what people are using in the wild on multiple machines, and bonus points for people who only use tools and mechanisms already built into the CentOS [base] repo. - KB

Um, yes. Is "advanced graphing class" a package, like mediawiki, or is it a php module? A php class is something that's part of the language and code, so asking how to set it up doesn't make sense here, that's programming. mark

Adaptec SCSI Card 2930LP supported by CentOS 5.x?
by Frank Thommen 17 Nov '09

Hi, for a specific application we need a low-profile SCSI card (PCI) with external 50pin connector. I thought about getting an "Adaptec SCSI Card 2930LP". However I was not able to find any usable information about wether this card is supported by Linux/CentOS 5.x or not. Does anyone have this card working with a CentOS 5.x machine? Alternatively: Are there any linux-supported low-profile PCI SCSI cards with 50pin connector which are supported by CentOS 5.x and which you can recommend?

RAIDs and JBOD?
by James Bensley 17 Nov '09

17 Nov '09

Hey Guys, I have some questions regarding a new home server I am going to build in the hopefully very near future (ASAP, I just need to finish planning everything and this is the penultimate hurdle), I will be creating a software RAID... Lets say I have three drives "knocking" around which are all 1TB SATA II drives but each made by a different manufacturer. I am going to guess that these couldn't be used in a RAID 5? Or could they? However could a similar result of 2TBs of data with redundancy be achieved with JBOD? Also regarding RAID 5, three drives of data to one for parity is the max ratio I believe? I.e. to expand this by adding another data drive, the original parity drive would no longer cover this and another would be required, is this correct? One more question about hot swappable drives, I understand that you can create RAID arrays with and without hot swappable drives but I am confused by this concept. I'm my experience with RAIDs I have only every delt with a RAID 1 that has degraded. I simply set the drive as offline, replaced it, set it to online and the RAID rebuilt itself all without restart the server and operation was never interrupted. So we can presume the server had hot swappable drives enabled yes? (It was a hardware RAID). With a software RAID is this still achievable? Thank you for reading.

Hallo I submitted this as a bug several weeks ago, but I wanted to ask around & see if anyone else has come across this.... I have a USB Buffalo Drivestation Quattro, with 4 1TB disks configured in raid5 as one 2.8TB (or so) disk, attached to a Cent 5.4 64 bit server (completely yum'd up to date) The disk is labeled as GPT, and formatted as a 2.8 TB ext3 partition (this issue also happens with xfs).

Problem with Yum on CentOS 5.4
by Niki Kovacs 16 Nov '09

16 Nov '09

Hi, I recently downloaded and burned the 5.4 DVD ISO. All my machines are now running 5.4, but these are installs I performed with 5.0, 5.1, 5.2 etc. and then progressively upgraded. Now I had to use 5.4 because a friend's laptop, a brandnew Fujitsu Esprimo Mobile, refuses to boot anything under 5.4. After a fresh install of the base system, first thing I do is 'yum update' with the default setup... only this time, nothing happens. I stays about a minute or two on 'Determining fastest mirror'... and then tells me : "Could not retrieve mirrorlist..." On the other hand, 'yum update' on all the other installs (from older CentOS disks) works correctly. What's wrong? Niki

Hi all, I'm having a strange problem in which a certain box won't boot any kernel newer than 2.6.18-53. I have a kickstart setup that installs a CentOS 5.1 base (which comes with kernel 2.6.18-53), and then I do a "yum update" to 5.3. However, when 2.6.18-164 gets installed, the box is rebooted, and it dumps me in a grub prompt. If I manually enter root, kernel, initrd and boot commands and point it at the -164 kernel, I am given "Error 13: invalid or unsupported executable format." But I can manually enter the -53 kernel and that boots fine. I tried backing down to the -128 and same problem. (all our updates come from our own mirrored repos and we only sync i386 directories) I enabled the menu and selected -164, and it gave me Error 13 the first time, and subsequent selects of the menu item resulted in Error 15: File not found. Now all of the above was with a separate /boot partition. Box is a dual core Xeon (E8500) with hardware SATA RAID on board. I'm pretty sure the old boxes were the same spec (but I don't have them onsite so can't verify that) and they successfully booted the -128 kernel. I've since rebuilt it with a single / partition. I then did all the updates, and updated my grub.conf to the following: default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz #hiddenmenu title CentOS (2.6.18-53.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-53.el5 ro root=LABEL=/ initrd /boot/initrd-2.6.18-53.el5.img title CentOS (2.6.18-164.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-164.el5 ro root=LABEL=/ initrd /boot/initrd-2.6.18-164.el5.img The menu came up but only showed the -53 option. The most common answer I seem to find with Grub's Error 13 is that a different architecture kernel was installed, but they're all the same; ie; i686 kernel from i386 repo.

Does anyone know if the program stunbdc, which prints one's IP address, is available in CentOS-5? It comes with the libnice package in Fedora-11. ------------------------------ [tim@rose ~]$ stunbdc -4 stun.ekiga.net Server address: 75.101.138.128 port 3478 STUN transaction started (timeout 600ms).
