I have two HP dc7800 convertible minitowers that are exhibiting the following issue: every 5-10 minutes, they will "freeze" for about 30 seconds, and then pick right back up again. During the freeze, it seems that nothing at all happens on the system; the clock doesn't even advance (it just picks up again with the next second, and that 30-or-so seconds are lost). I've tried both

Using CentOS 5.5 x86_64. I am trying to install software that comes on two discs. I can start the install just fine, but when it comes to taking out the first disc and putting in the second, the system won't let me eject it. I remember reading something on the internet once about something needing to be enabled to allow this to work, but I can't find it now. Does anybody have a clue as

Hi all, I've installed CentOS 4.4 in a box which previously had dual boot (XP SP2 and Ubuntu) I can run CentOS without problem but I can't boot XP SP2. When I try it the system simply hangs...

I have been trying to multiboot centos 4.1 and the current solaris express build 15. I have two hard drive s, the first one ( hd0 ) devoted to CentOS 4.1 and windows xp (no problems). The second drive (hd1) for Solaris 10 only. I tried to boot solaris from CentOS grub and got the following error messages: Booting Solaris 10 root(hd1,0) Filesystem type unknown, partition type 0Xbf kernel

Installing CentOS 6 on a lab full of workstations, and I want to disable fast user switching. With CentOS 5, I simply made sure that the "user_switch_enabled" entry in /etc/gconf/schemas/gnome-screensaver.schemas was set to false. However, that doesn't work with CentOS 6. I've found various proposed solutions to this issue, such as gconftool-2 --direct --config-source

I'm confused as to how to install updates for CentOS 5.6 without upgrading to 6.0. When I do a "yum check-updates", the new *-release packages for 6.0 are listed, so I don't think I want to do a simply "yum update". Is there a way to update 5.6 without going to 6.0? --- Mike VanHorn Senior Computer Systems Administrator College of Engineering and Computer Science

I am using CentOS 5.7. I have an /etc/security/access.conf file which has the following: + : root : LOCAL + : @mynetgroup : ALL - : ALL : ALL I thought this is supposed to restrict access to the system to only root and the accounts in the mynetgroup netgroup; however, anyone NIS account is still able to login. It appears that the access.conf is being ignored completely, so I'm thinking

Using CentOS 5.8: Currently on my workstations, when I press the power button the computer immediately does a 'shutdown -h now' (per /etc/acpid/events/power.conf). Is there a way to change it so that a confirmation dialog comes up, rather than an immediate shutdown? I assume that I am going to need to change that power.conf file to tell some program that the power button's been

I have a set of CentOS 5.7 workstations, on which I have turned of iscsid using 'chkconfig iscid off'. However, when some of them reboot, iscsid starts anyway. Also, when I do an 'service --status-all", iscsid is listed twice (this is true on both the workstations where iscsid starts and the ones where iscsid doesn't start), which seems to indicate, I think, that it is

According to all of the documentation I can find, an /etc/printcap file (or whatever filename is specified with the Printcap directive) is generated by cupsd ever time a printer is added or removed. On all of my CentOS 6.7 systems, this is NOT happening. I can restart cups and add or remove printers over and over and it still doesn't generate the printcap file. Is this a known issue, or is

Hello everybody, I installed Centos 6.2 on a computer with an older version of it in order to dual boot both of them. I managed to install the new OS on a physically seperated hard drive, and configured grub to make the newly installed OS the default one. Now the older OS won't boot and this error message shows: *"error 13: invalid or unsupported executable format"*. I attached

OK todays problem. I have a HP N54L Microserver running centos 6.5. In this box I have a 3x2TB disk raid 5 array, which I am in the process of extending to a 4x2TB raid 5 array. I've added the new disk --> mdadm --add /dev/md0 /dev/sdb And grown the array --> mdadm --grow /dev/md0 --raid-devices=4 Now the problem the resync speed is v slow, it refuses to rise above 5MB, in general

This is weird. As in, *deeply* weird. I ssh as root from one box to another (there are keys involved), and I go to vi a file, such as # line 1 # # line 2 # # line 3 # line 4 And what I see in vi is # line 3 # line 4 BUT, if I scroll the cursor over each line with the arrow key... I see all four lines. I've also looked at another file, and same thing. Just checked it out on the server I

Hello listmates, I have discovered a very strange SFTP problem which I can not connect to anything but NIS thus far. See here: http://www.linuxquestions.org/questions/linux-server-73/sftp-seems-to-fail-for-nis-accounts-under-openssh-5-x-816020/ http://readlist.com/lists/suse.com/suse-linux-e/38/193419.html Hence the question: is NIS (YP) still in use much anywhere for authentication? Thanks.

As I understand anaconda uses parted to partition (starting from centos 6), using this as example (kickstart configuration file): clearpart --all --drives=sda --initlabel part /boot --asprimary --size=200 --fstype=ext2 --ondisk=sda part swap --asprimary --size=16384 --fstype=swap --ondisk=sda part / --asprimary --size=512000 --fstype=ext4 --ondisk=sda part /scratch --asprimary --size=1 --grow

I don't know if this additional information helps. Looking at he efibootmgr output, is the centos entry pointing to the right place? Also, any idea why the update isn't being make permenant?

Hello, I have a Dell 1850 with dual Xeon procs and two u320 36Gb drives. I would like to set this up as dual boot system with 4.2 on disk 0 and 3.6 on disk 1. I imagine that I would install 4.2 first and then 3.6. Would I need to remove the other hard drive while installing a given version? Any gotchas? How about setting up GRUB? Anything special or does the install take care of it? Thanks,

Very Dumb Question : I have tried about four times now, using an old pentium2 with two hard drives (20 GB and 30 GB) to install both CentOS 4.4 and Fedora Core 6 in such a way as to enable dual-boot between them. I've tried it by installing 4.4 first, and then FC6. I've tried it by installing FC6 first, and then 4.4. I've tried it with and without giving the installer permission to
