I have many different centos machines that are hanging regulary. I believe this is due to something our application is doing - not a centos specific problem. When the machines hang, there is no access to the console or remote access(ssh, rsh, etc). Any tips on debugging this issue? It is becoming quite a show stopper as we migrate our product from Solaris to Linux. tia, FYI - The

I have an rpm I've created that has a dependency on a library provided by a third party. This dependency is not specified anywhere in my spec file yet the package seems to know about when I run: # rpm -qip --requires MyPackage.rpm The third party rpm is installed and uninstalled via a vendor-supplied script so that they can prompt you to accept licenses and so on. Problem is, the vendor

I have a dell precision 380: http://catalog.us.dell.com/CS1/CS1Page2.aspx?br=6&c=us&cs=555&fm=11210&l=en&s=biz with an Intel Matrix Storage Manager ICH7R RAID Controller http://www.intel.com/support/chipsets/imsm/sb/cs-020663.htm I need to get CentOS 3 installed on this thing but can't due to the fact that the controller is not supported in 2.4 kernels. There is a patch

Given that I have a machine with possibly multiple disks, each of which is bootable(has an MBR).... Is there a command that will query the BIOS and tell me which disk is the default boot disk. BTW - this is x86. The goal is to remotely reboot the workstation into the desired disk(which contain different centos versions). tia, -Mark -- Mark Belanger LTX Corporation

I have a user that is running centos on many machines. At each machine, the users is logged into a common account that is located elsewhere on the network. Meaning that everyone is logged on as user_x and accessing the home directory via NFS. All users are running gnome. On some of the machines, the nautilus process is pegging the cpu. At this time, I have no strace or other info to

I see in CentOS 3.6 - the release notes state that it has "improved support for dual-core processors" I got that from http://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/release-notes/as-x86/RELEASE-NOTES-U6-x86-en.html Where might I get more details about this improved support. Specifically I'd like to see if problems I'm having in 3.5 could be related to the kernel

Is it possible to take a Centos 3.7 machine - that was installed with the 32 bit version of CentOS, and update it to a 64 bit kernel? In other words - convert an i386 to ia64. I don't care about the applications, just the kernel. -Mark

Our very large and very complex application is running on CentOS 3.5 and Solaris. The CentOS machines are hanging about once per day. By "hanging" I mean the system is completely unresponsive either from the console or remotely via ssh. Totally locked. Does anyone have any tips for troubleshooting this sort of problem? -Mark -- Mark Belanger LTX Corporation

I've create a script and associated links(via chkconfig). The script runs in the expected runlevels at boot time, but does not run at all during shutdown(halt, reboot, etc). I swear I've done this a million times. What am I overlooking? # cat /etc/issue CentOS release 3.5 (Final) Kernel \r on an \m # chkconfig --list chnghst chnghst 0:off 1:on 2:off 3:off 4:off

The sys-unconfig script does not really work as advertised. For one thing it doesn't change the hostname. Is there an documentation about how to do the following: - Change the hostname, IP, networking etc for a currently networked machine - Change the hostname, IP, networking etc for a currently non-networked machine - Turn a networked machine into a non-networked machine. On a

Is there an equivalent command to nfsstat -m on Centos 3.4? On solaris it reports statistics for each NFS mounted file system i.e.: /mount/point from host:/some/path Flags: vers=3,proto=tcp,sec=sys,hard,intr,link,symlink,acl,rsize=32768,wsize=32768,retrans=5,timeo=50 Attr cache: acregmin=3,acregmax=60,acdirmin=30,acdirmax=60 On a related topic, how can I make a Centos3.4 nfs server

Can anyone recommend an flash mp3 player with around a 1 gig of memory that will work easily with linux. I had a a RAVE-MP that I was fairly happy with .... until I stepped on it :(. TIA, -Mark

Our large and complex build system is having very sporadic failurs as we try to update to CentOS 4.5. This takes the form of files that exist - and have existed for some time - not being found: file.whatever: No such file: No such file or directory This happens both with source files, .o's - meaning that the errors come from both the compiler and linker. The build storage is on NFS and the

Does sys-unconfig work as advertised in 4.x? Meaning that if I have a fully configured box on my internal net and run sys-unconfig, will I be able to power up the node on a totally different network and have things work providing I answer the questions properly. Most typically this will mean taking a box that is using NIS in DNS domain A, NIS domain B, and static IP addr and move it to DNS

For reasons I'd rather not go into, I need to get CentOS 3.anything on a Dell T3400: http://www.dell.com/content/products/productdetails.aspx/precn_t3400?c=us&l=en&s=bsd&cs=04 The hard drive is not seen at install time. Can someone point me in the right direction to see if this is possible and how to proceed? Regards, -mark

Is there a list somewhere of available updates for a given CentOS release? Something like this: https://rhn.redhat.com/errata/rhel4ws-errata.html Ideally I would like a something like: Bug Description Link to update 1111 kernel blah,etc http://some.rpm.com/1111.rpm -Mark -- Mark Belanger LTX Corporation
