When I run this command on centos 5.2 it just sets there nothing ever happens. Any ideas? I have ran it on two centos 5.2 machines. I can control C out. I am running it as root and a normal user both. Same thing - just sits there. jerry

Unable to install CentOS 5.2 on New HP Intel Core 2 Quad
by Michael Peterson 28 Aug '08

28 Aug '08

Our new lab has HP Intel Core 2 Quad systems with DVD/CDRW and SATA. I can provide the model number if needed. They stop on kernel startup when trying to boot the CentOS 5.2 boot CD. It is during ACPI. I have tried linux noprobe and linux pci=noacpi and linux noprobe pci=noacpi. I still cannot get to the first install screen. Fedora 10 Live will not but up either. I am using Fedora 9 from Live and DVD Install to teach a fall class and it works fine. Would CentOS 5.3 possibly work once it is released?

Strategy for using CentOS on laptops in an NIS environment
by Alfred von Campe 28 Aug '08

28 Aug '08

We use NIS (ypbind) and Kerberos at work for all our Linux and Unix systems. Home directories are mounted via autofs from an NIS map. Everything works just fine as long as all network resources are available (however, things turn ugly when the NIS servers are not reachable). Some users also want to start using laptops and bring them home or on trips to continue working while not at the office. Of course, their home directories won't be available and neither will other network resources. Creating local accounts with the same UIDs and local home directories solves most of the problems. However, I can't create a local account with useradd while ypbind is running because it complains that that account already exists. Is there a better way to create a local account then "service ypbind stop; useradd...; service ypbind start"? What are other strategies that you use to deal with off- network use in an NIS environment? Alfred

Centos 5.2, Firefox 3, and IPv6
by Robert Moskowitz 28 Aug '08

28 Aug '08

I am doing some testing and it almost seems as if Firefox 3.0.1 that comes with Centos 5.2 is NOT working with IPv6. Anyone know for sure? I am getting weird hang behaviours and other just not working things.

nsswitch.conf, ldap, local groups problem
by Mark Hennessy 28 Aug '08

28 Aug '08

I'm using CentOS 5.0,5.1, and 5.2 on several systems where I'm seeing this problem. Hello, I'm seeing a weird problem that perhaps someone has run into with groups. First, a little background. I was made aware of a problem with CentOS 5 where if the nscd password cache is clear and someone tries to log in if there is no network connection with an LDAP account that it just hangs. Even worse, if the machine is rebooted and it continues to have no network connection, even root login doesn't work. I messed around with nsswitch.conf to fix this problem. I altered these lines as so: passwd: files [!NOTFOUND=return] ldap shadow: files [!NOTFOUND=return] ldap group: files [!NOTFOUND=return] ldap and the problem seemed to go away. But now, here's the weird stuff: I have defined in my local /etc/groups file this line: group1:x:100:apache group2:x:101:apache 'getent group groupname' shows the right info: # getent group group1 group1:x:100:apache # sudo -u apache bash $ groups apache I revert back to my old config: # sudo -u apache bash $ groups apache group1 group2 Also, something else that's interesting. If I do this: passwd: files [!NOTFOUND=return] ldap shadow: files [!NOTFOUND=return] ldap group: ldap [NOTFOUND=continue] files and reboot, udev segfaults and the system freezes up after a few more seconds. Starting udev: /sbin/start_udev: line 43: 519 Segmentation fault "$@" $ARGS /sbin/start_udev: line 201: 523 Segmentation fault /sbin/udevd -d Wait timeout. Will continue in the background.[FAILED] Any advice?

System goes into read only mode - not the same as posted earlier
by Stephen Moccio 28 Aug '08

28 Aug '08

Hello all, I’m at my wits end trying to resolve this. We are running centos 4.5 on Intel hardware. Dual SCSI disk drives mirrored on an LSI Logic controller. Every once in a while and not always on the same server and not only on the local SCSI Drives. System A – Dual internal drives on /dev/sda System B – Dual internal drives on /dev/sdc with a DAS on /dev/sda. Each of these systems experienced a kernel mptbase error and placed /dev/sda into read only mode. Note again the /dev/sda isn’t always local. For system A – remounting in ro mode didn’t work and the system had to be rebooted. File system check and bad block checks showed nothing and when the system was rebooted – it was fine. A portion of the messages log is below. I would appreciate any ideas or directions.

RADVD address timeouts
by Robert Moskowitz 27 Aug '08

27 Aug '08

I am using RADVD to assign IPv6 addresses. It works for 'static' devices. I want it to work for devices that move to different networks without having to restart the network on those devices. So if I have a notebook on network Lab1 getting prefix 2607:7:4:1::64 and moves to network Lab2 where RADVD advertises prefix 2607:7:4:2::/64, I want the host to switch to the new address. This is NOT for MobileIP. Right now I get the new global address, but the old address never goes away. I have tried setting AdvPreferredLifetime, but that has not helped.

OT - Offline uncorrectable sectors
by Lorenzo Quatrini 27 Aug '08

27 Aug '08

I have few disk that have offline uncorrectables sectors; I found on this page how to identify the sectors and force a write on them to trigger the relocation of bad sectors on the disk: http://smartmontools.sourceforge.net/BadBlockHowTo.txt My question is: since I'm too lazy to follow all the procedure, do you think that a force rewrite of the full disk would work? Eg. "dd if=/dev/sda pf=/dev/sda bs=512" Shoudl this be done at runlevel 1 or offline or I can do it without too many worries, since I'm reading and rewriting the same data on the disk? TIA and sorry for the OT Lorenzo Quatrini

restarting static-routes-ipv6
by Robert Moskowitz 27 Aug '08

27 Aug '08

I want to change the contents of my /etc/sysconfig/static-routes-ipv6 and NOT restart the network. Is there a way to do this??? I know about ifup and ifdown for interfaces, but what about routing (and IP6 at that).
