Seeking translators
by Ralph Angenendt 23 Jan '09

23 Jan '09

Hi, anyone here who wants to really help out with the CentOS project? Then please check if you speak a language which is not yet on <http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.2> and help us translate the Release Notes for 5.3 (and 5.4, 5.6, 6.0 and whatever comes next). If you want to help out, please contact me *off* list. I have a slight timing issue (some parts have to be done by next Thursday, but that really is only a small part) and I'm sorry for not contacting this list earlier :) So if you can and want to help - send me a mail! Cheers, Ralph

OT: Looking for a timer/counter script
by Thomas Dukes 23 Jan '09

23 Jan '09

Hello, Was hoping someone could help me find a script for a website that increments at a specified rate over a specified period of time, something similar to the US National Debt site. I searched hotscripts but not really sure what this type script would be called. TIA PS I looked at the code for the national debt script but I can't make head or tails of it.

libpython2.4.so.1.0 i386
by Ed Donahue 23 Jan '09

23 Jan '09

I am running Kernel 2.6.18-92.1.18.el5 x86_64. I need /usr/lib/libpython2.4.so.1.0 for virtualbox. I have python-2.4.3-21.el5.i386.rpm installed which is supposed to provide it. Can I just grab the rpm and take out libpython2.4.so.1.0 and just put it in /usr/lib ? Not sure how to do that. I figured a sym-link would have the app not compile correctly (if at all) with the 64-bit lib. Tried yum with no luck: yum localinstall -y --nogpgcheck VirtualBox-2.1.2_41885_rhel5-1.i386.rpm --> Running transaction check ---> Package VirtualBox.i386 0:2.1.2_41885_rhel5-1 set to be updated --> Processing Dependency: libpython2.4.so.1.0 for package: VirtualBox --> Finished Dependency Resolution Error: Missing Dependency: libpython2.4.so.1.0 is needed by package VirtualBox rpm -qa|grep python|sort ... python-2.4.3-21.el5 python-crypto-2.0-1.2.el5.rf python-elementtree-1.2.6-5 python-game-1.8.1-1.el5.rf python-iniparse-0.2.3-4.el5 python-khashmir-4.4.0-1.el5.rf python-ldap-2.2.0-2.1 python-numeric-23.7-2.2.2 python-sqlite-1.1.7-1.2.1 python-urlgrabber-3.1.0-2 python-xdg-0.17-1.el5.rf rpm-python-4.4.2-48.el5

Question on upgrading hardware
by Bob Hoffman 23 Jan '09

23 Jan '09

For centos 5.x Two questions regarding upgrading hardware or system. 1- If I were to shut off the server and add more ram, switch out ram, remove one of the two cpus, or replace the two cpus with bigger or smaller ones.....Would I just be able to restart the server or would I have to do something with the configuration somewhere? 2- If I built another system, slightly different motherboard but most of the rest the same as far as hardware, would taking a drive from the old system and adding it to the new system work correctly and recognize what it needs? Thanks for any advice on the upgrading.

where did all the nonfree rpms go? Nvidia? xine-lib-mp3?
by Paul Johnson 23 Jan '09

23 Jan '09

I installed Centos on some machines that need long term support. I'm running up against some simple user convenience issues. How to play MP3? I've been really puzzled today that the addon rpm sites like livna, rpmforge, rpmfusion, epel, don't seem to have something like amarok-mp3 or xine-lib-mp3. What am I missing? It can be done in Ubuntu, Debian, and Fedora Linux. In the worst case scenario, what must be done? get the xine source code and build an rpm that includes the mp3 components? Do you have Nvidia cards? Then I noticed there is a new Nvidia proprietary driver on www.nvidia.org, and I can't find an rpm package for it, or for the previous 2 releases of the nvidia driver. The place to get those packages used to be rpm.livna.org, but that is now moved to rpmfusion, but on the rpmfusion site, the nonfree folders are empty. Oh, well. Just singing a complaining song. pj -- Paul E. Johnson

start network installation with HP 8530w with Intel ethernet card
by MOKRANI Rachid 23 Jan '09

23 Jan '09

Hi, I have an HP 8530w laptop. I need ti instal it under CentOS 5.2 x86_64 - kernel 2.6.18-92. The network card is not recognized. I have add the driver e1000e-0.5.11.2 (dowload from Intel site). After compiled and installed the driver, all work fine! But I need to make a network installation and the Intel network card should be recognized before. I found the following script on the net and try it. ------------------------------------------------------------------------ ------------------------------ wget http://my_web_server/CentOS/5.2/x86_64/images/diskboot.img cp diskboot.img diskboot.orig.img mkdir diskboot_mnt mount -o loop diskboot.img diskboot_mnt mkdir initrd_extracted cd initrd_extracted gunzip < ../diskboot_mnt/initrd.img | cpio -i --make-directories cd .. mkdir modules_extracted cd modules_extracted gunzip < ../initrd_extracted/modules/modules.cgz | cpio -i --make-directories cd 2.6.18-92.el5/x86_64 rm e1000e.ko wget http://my_web_server/e1000e.ko # Now put humpty back together again cd ../../ find . -print |cpio -o -Hnewc | gzip -c9 > ../modules.cgz cd .. cp -fp --no-preserve=all modules.cgz initrd_extracted/modules/ cd initrd_extracted find . -print |cpio -o -Hnewc | gzip -c9 > ../initrd.img cd .. cp -fp initrd.img diskboot_mnt/ # cleanup umount diskboot_mnt rm -rf diskboot_mnt/ initrd_extracted/ initrd.img modules.cgz modules_extracted/ mv diskboot.img diskboot.mod.img dd if=diskboot.mod.img of=/dev/sdb ------------------------------------------------------------------------ ----------------------------------------- After trying to start on a USB key, the network card is not recognized again :-( Something is missing ... how to add this network driver for starting a network installation ? Anybody do this before ?

Yes, using an rpm package is better, as the packaged drivers do not remove libGL.so, for example, like the nvidia driver does. Cheers, Ralph

Re: [CentOS] Antivirus for CentOS? (yuck!)
by Les Bell 22 Jan '09

Adam Tauno Williams <awilliam(a)whitemice.org> wrote: >> CLAMAV, or any package, isn't THE answer, it is part of an answer. And PCI/DSS requires a server be scanned on a regular basis. Fighting against that directive just makes no sense. You should scan an entire system on some interval regardless of OS. << It's worth noting that the type of scan required by PCI DSS is not a filesystem scan by an antivirus product. It is a vulnerability scan performed by an Approved Scanning Vendor. Some other miscellanous points triggered by posts in this thread that I've read this morning: According to the Verizon 2008 Data Breaches Report, in over 90% of cases where a successful attack exploited a vulnerability, there was a patch available for at least six months prior to the breach. So the first thing we can say is that there is good reason to patch your system - it's definitely an effective activity. While the most popular attack methods of cybercriminals are hacking and malcode (again, the Verizon report confirms this), malcode is much more popular in the Windows world and hacking is the method of choice against Linux boxes, imho (SSH brute-forcing worms notwithstanding). This means that anti-virus products will be less effective in safeguarding the data on a Linux box, and host intrustion detection systems are correspondingly more effective. Most attacks against servers are conducted against the application layer code (PHP vulnerabilities, especially, but also SQL injection, etc.) Again, anti-virus products are not effective here, particularly since the original poster seems to be running custom code (internally-developed or outsourced). The best controls here will be HIDS like AIDE and Tripwire, as well as network IDS. An attacker who exploits a server might upload some recognisable malware, and an anti-virus scanner might pick it up, but I'm not sure whether (e.g.) ClamAV has signatures for stuff like eggdrop IRC servers, phishing sites and other stuff sometimes turns up on compromised hosts. The bulk of the signature database is undoubtedly Windows malware. However, a determined attacker, who knows what the server hosts, is much more likely to either use SQL injection or command injection techniques to extract credit card info (use NIDS to detect this) or to install a rootkit to allow him to come and go more easily (and HIDS will detect this). Remember, there are two problems to be solved here: a) Get the systems past the PCI-DSS Assessor b) Do something useful to actually protect the systems It would be great if both problems had the same solution, but that depends on how clueful the Assessor is (and how artfully the original poster can "manage" him). Right now, the original poster's employer is paying him to solve a), and will probably only worry about b) much later, should the excrement actually hit the fan. If installing ClamAV is what it takes to solve a), just do it and then get to work on b).

lvm metadata recovery
by Brian Krusic 22 Jan '09

22 Jan '09

Hi all, I am looking for a way to recover my primary VolGroup00 that has my root partition. Here is my scenario; 1 - I add an external drive to my VolGroup00 which is sdc1. 2 - I make that external drive a snapshot of my / 3 - After I remove that new volume of sdc1 using lvremove, all os fine. 4 - When I turn off the sdc1 drive, I loose my VolGroup00. If by chance, the sdc1 breaks in such a way that the system doesn't se it any more and the system happens to reboot, it will longer recognize a VolGroup00 and therefore not boot. I backed up my original /etc/lvm to /etc/lvm.backup and would like to know how I can restore it from booting to a LiveCD and simply restoring the files located in /etc/lvm.back/backup/VolGroup00 which is my original metadata config. - Brian
