Wondering about CentOS 5.1 functionality

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, I'm giving serious thought to loading 5.1 on my Inspiron 1501 laptop, but I'm wondering about certain hardware support such as the following: - - Broadcom Wireless Adapter - 1390 Wlan (bcm43xx) - - USB (Pny Memory Stick - everytime on previous version CentOS has eaten the damned things) - - pptp vpn client(s) Any comments? thanks, Mark -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4-svn0 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFHfwl4AHUWFbtwPigRAvYRAJ9rPLV4QndZfauCtT2NaRVNgxxO+gCfVOD6 gzum1eGG/6Bxa22CIU2zDl8= =zTJx -----END PGP SIGNATURE-----

/etc/passwd aand /etc/shadow out of sync on 4.6 box
by Joe Klemmer 07 Jan '08

07 Jan '08

Fellow list members, I recently tried to add a user to a little used server that hadn't see a change in users for quite a while. When I use system-config-users I get an error alert that says - The user database cannot be read. This problem is most likely caused by a mismatch in /etc/passwd and /etc/shadow. The program will exit now. I awk'ed out the user ID's and ran diff. That came back with the shadow file having two more users than the passwd file. Ok, fine, whatever. But the trick now is how to fix this. Can I just use vi and delete the offending lines from the shadow file? Is there a utility or script that will sync them in a less potentially destructive way? Any pointers to info on this are greatly appreciated. Thanks, Joe -- Boring Home Page - http://www.webtrek.com/joe See my blog, sumo game ranks and other interesting junk

PXE problem after CentOS reboot
by Andrey Slepuhin 07 Jan '08

07 Jan '08

Dear folks, We are installing a large diskless cluster using CentOS 5.1. The hardware is pretty new - Supermicro X7DWT boards with Harpertown CPUs. Unfortunately we have some PXE-related problems described by the following scenario: 1) Set up DHCP, TFTP and NFS on a server, prepare PXE kernel and initrd - fine. 2) Start up the node using PXE for the first time - fine. 3) Reboot the node - PXE boot fails for all next attempts. We see that a server gets DHCP requests and answers them, but a node doesn't response with DHCP ack. The typical DHCP log is: Jan 5 09:14:34 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:34 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:36 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:36 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:40 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:40 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:48 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:48 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to 00:30:48:7e:24:a6 via eth1 4) Anything like DHCP server restart, node reset, node power on/off doesn't help 5) The only thing that will enable system to boot again over PXE is to perform "bmc reset cold" command on a node using ipmitool - yes, we have IPMI card sharing the same Ethernet interface. After that we can boot CentOS again. 6) When Linux is loaded, if we reboot a node using "bmc power cycle" instead of reboot or shutdown, a node will boot for the next time without problems 7) There are no problems with a second GbE interface (without IPMI) 8) So our guess is that Linux on a reboot leaves Ethernet device in some state that cause brain damage for IPMI+PXE combination. We tried to play with some e1000 driver options, we are also tried latest Intel driver - nothing helps. Do you have any idea what goes wrong? Any help will be much appreciated.

tomcat still sees jvm version 1.4.2 in Cent OS 5
by Isaac Gonzalez 07 Jan '08

07 Jan '08

i chose to install tomcat during the OS install as well as java....however, since I needed to use a different jvm, i used the method described in http://wiki.centos.org/HowTos/JavaOnCentOS for Sun jdk 1.5.0_13 and it worked fine as I can tell, as using the alternatives --config java command, i see both 1.4.2 and 1.5.0 versions and choosing the 1.5.0 version yields the right version when doing a "java -version" command....also doing a "which java" also points to the right location for the java 1.5.0 install...everything appears fine except that tomcat still sees java 1.4.2 as its jvm version... I have tried setting the path to JAVA_HOME in the tomcat5.conf as well as set the JAVA_HOME & JRE_HOME environment variable as a script under /etc/profiles.d....its as if tomcat is ignoring this and still using java 1.4.2! # /etc/init.d/tomcat5 version Server version: Apache Tomcat/5.5.20 Server built: Sep 27 2007 12:16:07 Server number: 5.5.20.0 OS Name: Linux OS Version: 2.6.18-8.1.15.el5 Architecture: i386 JVM Version: 1.4.2 JVM Vendor: Free Software Foundation, Inc. # java -version java version "1.5.0_13" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05) Java HotSpot(TM) Client VM (build 1.5.0_13-b05, mixed mode) # alternatives --config java There are 2 programs which provide 'java'.

How do I blank or overwrite DVD-RW disks in CentOS 5?
by Robert Nichols 07 Jan '08

07 Jan '08

I'm trying to use DVD-RW ("minus RW") disks in my LG GSA-4040B drive. I can write a new disk just fine, but can't find any way to blank or re-use a disk. When I run xcdroast and click on the "Blank CD/DVD+-RW" button, I get "Error while blanking." Here is last part of the dialog: Using generic SCSI-3/mmc DVD-R(W) driver (mmc_mdvd) Driver flags : SWABAUDIO BURNFREE Supported modes: PACKET SAO Drive buf size : 1245184 = 1216 KB Drive DMA Speed: 11772 kB/s 66x CD 8x DVD cdrecord.prodvd: Success. set streaming: scsi sendcmd: no error CDB: B6 00 00 00 00 00 00 00 00 00 1C 00 status: 0x2 (CHECK CONDITION) Sense Bytes: F0 00 05 00 00 00 00 10 B6 00 00 0D 21 00 00 00 Sense Key: 0x5 Illegal Request, Segmant 0 Sense Code: 0x21 Qual 0x00 (logical block address out of range) Fru 0x0 Sense flags: Blk 0 (valid) cmd finished after 0.004 s timeout 40s Current Secsize: 2048 cdrecord.prodvd: Cannot set speed/dummy. ATIP start of lead in: -150 (00:00/00) I've had similar lack of success trying to blank or overwrite using cdrecord or growisofs. The disks I'm using are Sony 2X DVD-RW 4.7GB, which _should_ be compatible with the drive AFAICT. The drive is happy to write to a new disk. I'm not using KDE, so I'd prefer a command-line or Gnome tool. -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.

Weird crash with CentOS 5.1
by Jean-Yves Avenard 07 Jan '08

Dear all. I'm experiencing a weird crash with one of our desktop running CentOS 5.1 We have 5 machines identical, onle one has this problem. Right after it starts, it will kernel panic. Unfortunately, from the backtrace this is all I've managed to get : serial port isn't working. So it's a manual copy of what the screen show.

Windows has no problem and will run just fine (so I believe this is not a hardware issue). Interestingly, this machine worked fine for several weeks and one day decided to crash within the first few seconds of boot. I have tried with several kernel, including the latest one as of today: not working any better. If I boot the CentOS DVD, when it comes to searching for existing CentOS installation, it will crash just the same. If I format the linux partition, I can then re-install CentOS, update it just fine... Then a few days later it will crash just the same right after booting. This machine is running a Gigabyte P35-DS3P motherboard, with 2GB of DDR2-667MHz RAM, an Intel core-duo quad: Q6600. It has two 250GB hard drive in RAID1 using the bios RAID support (so I can have RAID on both Windows and Linux). It's running the 32 bits version of CentOS 5 Any ideas what the problem could be? Any help will be greatly appreciated. Thank you Jean-Yves

nForce 630i Chipset, unable to get integrated nic working
by David Levinger 07 Jan '08

07 Jan '08

Hello everyone, I've also posted this onto the Network support forums but figured I'd shoot it to the mailing list as well. I recently purchased a ECS GF7100PVT-M motherboard and now I'm wishing I'd investigated driver support a little better before I did! I was able to get Centos 5.1 XEN Kernel installed but have been having a helluva time getting the on board NIC going. The MB is running a nForce 630i chipset and has the nic card listed as a Realtek 8111B. I've downloaded what I believe to be the latest Realtek drivers and if I do an lsmod I can see the r8168 module present. I've tried adding the line alias eth0 r8168 to my /etc/modprobe.conf file but it hasn't gotten me anywhere, I've also tried with Nvidia's forcedeth module to no avail. Does anyone have some ideas of what I could try next? Do I need a newer version of the forcedeth driver? Is this chipset not going to work with Centos 5.1? Is it a Xen related issue? lspci shows "Ethernet controller: nVidia Corporation Unknown device 07dc (rev a2)" Any thoughts/pointers would be much appreciated. Thanks in advance, David
