centos 5.1 kickstart CD and intel 82576 driver
by aurfalien＠gmail.com 21 Aug '09

21 Aug '09

Hi all, I've got a Centos 5.1 kickstart that I must continue to use. How can I update the kick start image so that it recognizes Intel gigabit 82576 nic? BTW, I compiled the driver I need and have this igb.ko file. How do I incorporate that into my initrd.img file that I see on the kickstart CD that is probably my kickstart boot OS. Thank you very much in advance. aurf -

Arg... jdk problem on centos 5

I have downloaded the EE JDK 5.07 for Linux from Sun. If I try and run java_ee_sdk-5_07-linux.bin as a normal user it works fine and I get the gui installer to appear. However if I run it as root, I get this output and then if hangs indefinitely ultimately requiring a kill -9 to stop: [root@canthus Downloads]# ./java_ee_sdk-5_07-linux.bin Checking available disk space...

DNS Server Recommendations
by Hugh E Cruickshank 20 Aug '09

20 Aug '09

Hi All: I am looking for some possible recommendations on the handling of our internal DNS services. First some background... Until recently our entire network was located within a single facility with internal DNS services provided by our CentOS 4.7 (using BIND). While I had problems with DHCP/DNS communications it was basically working. At the beginning of the month we moved the production servers (a couple of RHEL5.3 boxes with a Windows 2008 server) to a new facility connected to the old facility via a VPN. We are still running with our DevSys as the DNS server but I would like to make the two locations at least partially independent. I have been doing some research (probably enough to be really dangerous to myself<g>) and it looks like I need to setup a master/slave setup. Here are my questions... 1. Is the BIND master/slave the appropriate approach? 2. Can I have each subnet be a master for itself and a slave for the other subnet? 3. Any pointers to applicable docs/examples? 4. Can you recommend a "front end" for BIND (we have webmin installed but I have yet to start working with it)? Any and all thoughts, suggestions, criticisms gladly accepted. TIA Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com

what is RAID "background initialization" ??
by mcclnx mcc 20 Aug '09

20 Aug '09

we have DELL server (CENTOS 4.X) with MD1000 connect on it. One of Raid5 (internal 4 disks) has hard disk bad and I replace it. I saw /var/log/messages have following entry: ======================================= Aug 18 15:33:20 host1 Server Administrator: Storage Service EventID: 2049 Array disk removed: Array Disk 0:11 Controller 1, Connector 0 Aug 18 15:34:09 host1 Server Administrator: Storage Service EventID: 2052 Array disk inserted: Array Disk 0:11 Controller 1, Connector 0 Aug 18 15:34:09 host1 Server Administrator: Storage Service EventID: 2065 Array disk Rebuild started: Array Disk 0:11 Controller 1, Connector 0 Aug 19 00:42:58 host1 Server Administrator: Storage Service EventID: 2124 Redundancy normal: Virtual Disk 0 (Virtual Disk 0) Controller 1 (PERC 4e/DC) Aug 19 00:42:58 host1 Server Administrator: Storage Service EventID: 2092 Array disk Rebuild completed: Array Disk 0:11 Controller 1, Connector 0 Aug 19 00:45:53 host1 Server Administrator: Storage Service EventID: 2127 Background Initialization started: Virtual Disk 0 (Virtual Disk 0) Controller 1 (PERC 4e/DC) ============================================= My questions are: 1. why after "disk rebuild" there have "background initialization"? 2. is all kind of configuration (e.g. RAID0, RAID10, ...) need perform "background initialization"? 3. if I run heavy application, will it hurt "background initialization" and "disk rebuild"? Thanks. ___________________________________________________ 您的生活即時通－溝通、娛樂、生活、工作一次搞定！ http://messenger.yahoo.com.tw/

Funny stuff in SELinux -- /usr/lib/libGL.so.1.2.#prelink#.4GxqM1
by David McGuffey 20 Aug '09

20 Aug '09

Received this SELinux warning: Summary: SELinux is preventing ld-linux.so.2 from loading /usr/lib/libGL.so.1.2.#prelink#.4GxqM1 which requires text relocation. Detailed Description: The ld-linux.so.2 application attempted to load /usr/lib/libGL.so.1.2.#prelink#.4GxqM1 which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests (http://people.redhat.com/drepper/selinux-mem.html) web page explains how to remove this requirement. You can configure SELinux temporarily to allow /usr/lib/libGL.so.1.2.#prelink#.4GxqM1 to use relocation as a workaround, until the library is fixed. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package. Allowing Access: If you trust /usr/lib/libGL.so.1.2.#prelink#.4GxqM1 to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/usr/lib/libGL.so.1.2.#prelink#.4GxqM1'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t textrel_shlib_t '/usr/lib/libGL.so.1.2.#prelink#.4GxqM1'" Fix Command: chcon -t textrel_shlib_t '/usr/lib/libGL.so.1.2.#prelink#.4GxqM1' Additional Information: Source Context unconfined_u:system_r:prelink_t:s0 Target Context unconfined_u:object_r:lib_t:s0 Target Objects /usr/lib/libGL.so.1.2.#prelink#.4GxqM1 [ file ] Source ld-linux.so.2 Source Path /lib/ld-2.9.so Port <Unknown> Host desk.mcguffeyfamily.net Source RPM Packages glibc-2.9-3 Target RPM Packages Policy RPM selinux-policy-3.5.13-68.fc10 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name allow_execmod Host Name desk.mcguffeyfamily.net Platform Linux desk.mcguffeyfamily.net 2.6.27.29-170.2.79.fc10.i686 #1 SMP Fri Aug 14 21:11:41 EDT 2009 i686 i686 Alert Count 1 First Seen Wed 19 Aug 2009 08:43:01 PM EDT Last Seen Wed 19 Aug 2009 08:43:01 PM EDT Local ID 194f2933-b29d-4605-9248-a056af793e4d Line Numbers Raw Audit Messages node=desk.mcguffeyfamily.net type=AVC msg=audit(1250728981.756:551): avc: denied { execmod } for pid=7313 comm="ld-linux.so.2" path="/usr/lib/libGL.so.1.2.#prelink#.4GxqM1" dev=sda2 ino=1733603 scontext=unconfined_u:system_r:prelink_t:s0 tcontext=unconfined_u:object_r:lib_t:s0 tclass=file node=desk.mcguffeyfamily.net type=SYSCALL msg=audit(1250728981.756:551): arch=40000003 syscall=125 success=no exit=-13 a0=bd0000 a1=6a000 a2=5 a3=bf974f60 items=0 ppid=7297 pid=7313 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts0 ses=84 comm="ld-linux.so.2" exe="/lib/ld-2.9.so" subj=unconfined_u:system_r:prelink_t:s0 key=(null) A few minutes later I got the same warning but it was about SELinux is preventing ld-linux.so.2 from loading /usr/lib/libGL.so.1.2.#prelink#.1brWwM which requires text relocation.

Updated livecd building tool
by Patrice Guay 19 Aug '09

19 Aug '09

I updated the livecd-tools package from version 013 to 014. This update introduces new interesting features like : - support for Xen kernel - built-in md5sum into the resulting LiveCD ISO - a new API See https://projects.centos.org/trac/livecd/wiki/GetToolset for instructions on how to get this updated toolset. Since it is a major update, I expect some bugs. I am looking for feedback from people interested in respining their own LiveCD kickstart files with the new tool. As usual, if you encounter a bug or would like to submit a patch, create a ticket from the CentOS LiveCD project page: https://projects.centos.org/trac/livecd -- Patrice Guay patrice.guay(a)nanotechnologies.qc.ca

replacing permissions on uploaded windows files
by Dave 19 Aug '09

19 Aug '09

Hello, I've got a CentOS box and users are putting Windows long files on it, files with " " and " - " in their filenames. I'm trying to adjust the permissions as well as user and group membership and i'd like the changes to be sticky. On the tld i've set permissions of 2755 and am trying to batch convert the files and subfolders in it. I've done this: find tld -type f |xargs chmod 644 {} \; find tld -type d |xargs chmod 755 {} \; Both of these are failing due to the spaces and dashes. I've tried enclosing those {} in quotes, no good. Has anyone done this with shell or perhaps perl? Thanks. Dave.
