Overheating on laptop as compared to RHEL
by Krishnan V 16 Oct '13

16 Oct '13

Hi, I have an acer 5738g laptop on which i tried out the centos6.4 live CD. The laptop feels noticable hotter and i check the temperature using something like cat /proc/acpi/thermal_zone/. The temperatures are around 57-60 degrees when the laptop is just idling, ie, just the desktop and the terminal window open. I install lm_sensors using yum and it installs successfully, but there is no noticable reduction in temperature. I have faced this same problem using different varities of gnu/linux distributions: slackware, lubuntu, mandriva and now centos. By a freak chance, i had a chance to run RHEL 5.4 and to my great surprise, the temperature at idling was 43, similar to Windows(which came as default). In fact, the temperature control by rhel was what made me think of trying centos. I tried the lm_sensors configuration on rhel and it was not even able to load the correct modules, yet the temperature control was better. Now, i am not sure if lmsensors are for detecting temperatures only but also for cotrolling temperature. I am also aware that this particular model is notorious for heating problems, and there are suggestions for cutting case for better air flow. However, i do not want to try this solution, but the temperature control by rhel gave me some hope! Posibly i am wrong. If anyone has a suggestion, or needs more information, pl. let me know. Thanks!

hung nfs mount
by Les Mikesell 16 Oct '13

16 Oct '13

What is the best approach when an nfs mount hangs on a client but the server is OK? I have mount options of: rw,bg,soft,intr,rsize=32768,wsize=32768 but whatever it did was not interruptable and would not shut down. There were some: Oct 15 09:08:32 dev-ngf-l-01 kernel: INFO: task gnome-settings-:19169 blocked for more than 120 seconds. Oct 15 09:08:32 dev-ngf-l-01 kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. messages on the console and /var/log/messages. Is this a bug or there a way to avoid it? -- Les Mikesell lesmikesell(a)gmail.com

Correct? @Terre: I don't know how VIA C7 CPUs stack up against the Intel Atom CPUs in terms of performance, but they're low power consuming x86 processors.

xorg updates hose GUI with Nvidia driver
by B.J. McClure 16 Oct '13

16 Oct '13

Just a heads up that once again an xorg update has removed the link in /usr/lib64/xorg/modules/extensions that points to libglx.so.325.15 in /usr/lib64/xorg/modules/extensions/nvidia thus breaking X. This should only effect those with nvidia proprietary driver. One of the following packages is the culprit but I have not tried to narrow it down. I have done updates and downgrades several times and it is quite reproducible. Oct 15 17:53:01 Updated: xorg-x11-server-common-1.13.0-11.1.el6.centos.1.x86_64 Oct 15 17:53:03 Updated: xorg-x11-server-Xorg-1.13.0-11.1.el6.centos.1.x86_64 Oct 15 17:53:03 Updated: xorg-x11-drv-mga-1.6.1-8.el6_4.x86_64 Oct 15 17:53:04 Updated: xorg-x11-drv-synaptics-1.6.2-11.el6_4.1.x86_64 Oct 15 17:53:04 Updated: xorg-x11-drv-mach64-6.9.3-4.1.el6_4.x86_64 Cheers, B.J.

Re: [CentOS] no group package selection via PXE network installation

You need more than 512 MB of RAM to do a graphic installation, I've forgotten the exact requirement. As for text install, RedHat has crippled it--you cannot choose packages or disk layout. Apparently Anaconda developers decided to focus upon the graphic install, and so, the only way to customize a text based install is to use a kickstart file. So, your options are to increase the RAM so you can get a GUI installation, use a kickstart file, or use an operating system where the developers still think like system administrators rather than smart phone users.

installing on second drive
by Steve Clark 15 Oct '13

15 Oct '13

Hello list, I have two drives - the first drive currently has F14 on it. The second drive is empty. If I select custom partition and only partititon and format the second drive, will CentOS install on the second and not touch the first drive? This is using the installer from the CentOS 6.4 Live DVD. Thanks, -- Stephen Clark *NetWolves* Director of Technology Phone: 813-579-3200 Fax: 813-882-0209 Email: steve.clark(a)netwolves.com http://www.netwolves.com

setuid or other ideas
by Gregory P. Ennis 15 Oct '13

15 Oct '13

Everyone, I am working on a Centos 5.9 system. I have an need to be able to activate a piece of software from /etc/smrsh that is activated when sendmail delivers the e-mail to this piece of software. I would like this piece of software to take on the user and group identities that are different than 'mail' which is what happens now. I want to use a user and group that is not root), so that the piece of software will be able to write (concatenate) to a file. I have never used setuid, but it appears that this will only allow a piece of software to be set to root. I really do not want to give that kind of privilege to this piece of software. Any ideas? -- Greg Ennis PoMec Corporation www.PoMec.Net

no group package selection via PXE network installation
by Riccardo Castellani 15 Oct '13

15 Oct '13

I'm trying to install centos 6.4 on my server A (which has 512 MB ram and no cdrom) by PXE. I exported installation tree 'CentOS-6.4-i386-bin-DVD1.iso' via http on server 'Z', all according to Centos howto (copied vmlinuz, pxelinux.cfg, initrd.img , started tftpd+dhcpd services) Boot process is OK (in text mode! I think it's a memory problem); it's required keyboard type, time zone, network parameters, disk partitions, ... but no installation type is required (basic, minimal, server, ...) and no packages selection ! Installation goes on installing the packages but without choosing them! I'd like to choose type of installation and the details of packages, any options as I used directly installation dvdrom1. I don't want to use kickstart file ! My 'pxelinux.cfg/default' file: timeout 9000 default menu.c32 menu title ########## PXE Boot Menu ########## label 1 menu label ^1) Install CentOS 6 kernel centos64/vmlinuz append initrd=centos64/initrd.img repo=http://a.b.x.y/centos6 devfs=nomount ramdisk_size=152000 label 2 menu label ^2) Boot from local drive localboot What do you think ?
