[CentOS] 6.3 installer keeps cycling in a 10 second countdown to boot
Hi. I've been running CentOS 5 for ages. (Thanks!) I went to install 6.3 - I downloaded the 64-bit DVD 1 image, and put it on a USB drive. Booted into a screen that said boot will start in 10.. 9... 8.. 7.. 6.. 5.. 4.. 3.. 2.. 1.. 10.. and so on, infinite loop, the boot never starts. I tried booting in text mode, but it doesn't boot, just goes back to the menu. Is there some way to find out why the centos installer refuses to start? I used to have CentOS 5 on this system. I'd expect 6 to work. Thanks, Aleksey ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS-docs] Update to CentOS FAQ: I installed the x86_64 version, so why do I have i386 packages, and can I get rid of them?
Hi, thank you for maintaining the CentOS FAQ at http://wiki.centos.org/FAQ/General it is very helpful. I used to follow the procedure outlined in 22. I installed the x86_64 version, so why do I have i386 packages, and can I get rid of them? ( http://wiki.centos.org/FAQ/General#head-357346ff0bf7c14b0849c3bcce39677aaca528e9 ) but it recently stopped working. the last step, yum reinstall \* now throws errors about missing dependencies. (This is starting from CentOS 5.4) However if I run yum -y update as the very first step, and then do the procedure, it works beautifully. I don't know what is the cause of this, but in the course of troubleshooting it, I've learned that rpm -Va | grep ^missing will tell me if any files are missing, and if yum reinstall \* is even necessary. It is faster to run the package verification and skip the reinstall, as reinstall involves re-downloading all the packages over the network. I'd like to suggest the FAQ be updated with: Run rpm -Va | grep ^missing to see if any files are missing. If there are, reinstall with yum reinstall \* Best, -at ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs

which I think will allow the httpd access to read and write from shared memory?
Is that right? What are the risks involved in opening this? I notice it is

using /usr/sbin/setseebool, but I don't see an sebool that deals with shm...

Re: [CentOS] system stuck with 2.6.18-128 kernel. how to move to 2.6.18-194.17?
Thank you very much for your replies and suggestions! Turns out I have a broken RAID. I checked the failed out drive by mounting read-only the /boot partition, and it is configured to boot the older kernel version (the one the system actually boots). Like Phil said, the OS is seeing one thing, and GRUB another. Questions: 1. How do I fix the array? (How do I put the failed out drive back in? (I hope it is a small failure that the software RAID can recover from, like a few bad blocks or something. Otherwise I am willing to replace the drive.) # mdadm /dev/md0 --add /dev/sda1 mdadm: Cannot open /dev/sda1: Device or resource busy # Maybe it's busy because the system really booted off it? Maybe I can edit grub.conf to change hd(0,0) to hd (1,0) and reboot. Where do I do that, in /dev/sda1 or /dev/sdb1? I guess I could do it in both places. What do you think? Note: I was able to add /dev/sda3 to /dev/md1, and it is resync'ing the array now. # mdadm /dev/md1 --add /dev/sda3 mdadm: re-added /dev/sda3 # 2. Is there a different configuration I should adopt, so that OS and GRUB agree on what device to boot from? Or is this the price I pay for using software RAID rather than HW RAID? Data: The /etc/grub.conf sym link is set up correctly: lrwxrwxrwx 1 root root 22 Mar 17 2009 /etc/grub.conf - ../boot/grub/grub.conf My /boot filesystem lives on a RAID 1 array: /dev/md0 on /boot type ext3 (rw) /proc/mdstat shows only /dev/sdb is still in the RAID 1 mirror: Personalities : [raid1] md0 : active raid1 sdb1[1] 104320 blocks [2/1] [_U] md1 : active raid1 sdb3[1] 275964480 blocks [2/1] [_U] unused devices: none For some reason, it does not show F for disk failure.

[CentOS] system stuck with 2.6.18-128 kernel. how to move to 2.6.18-194.17?
Hi. I just noticed I had a CentOS 5.3 system that I updated to CentOS 5.5 a few days ago, and I just ran yum -y update again to get the latest kernel, and I just noticed it still has the old 2.6.18-128 kernel instead of the new 2.6.18-194.17. What gives? /etc/grub.conf points at 2.6.18-194.17, but when I reboot, 2.6.18-128 comes up. Any suggestions?

I read up on prelink as suggested; and used ldd /sbin/mkfs.ext3 to see what the dependencies (libraries) are. There are 13 dependencies; file size is the same between servers but md5sum's are different! Most of these libraries have other libraries they call; I finally drilled down to ld-2.5.so which is statically built. Same thing: same file size, same datestamp, same package version; but the binary is actually different; yet rpm -V does not complain. Why?

Re: [CentOS] Pause time
2010/4/19 cahit Eyigünlü cahit.eyigu...@gmail.com: i want to pause my cent os time and date in a spesific date :D is it possible ? You can set your clock back a minute every minute from cron using the date command. Try: date -s now - 1 minute If that's not good enough, you can write a loop that resets your clock back a second every second, again using the date command. while true do date -s now - 1 second sleep 1 done That should make time appear to stand still at the HH:MM:SS level. Another possible method is to pause time itself. However your computer won't work any more, and will remain frozen without any changes.

[CentOS] How to get Bugzilla working on CentOS 5.2 with SELinux turned on?
Hi. Has anyone figured out how to get Bugzilla working on CentOS 5.2

I've run
chcon -R --reference=/var/www/html /path/to/bugzilla
and added the following module (generated by audit2allow), but am
still getting errors in my Web browser tryinig to use Bugzilla:
Software error:
Can't connect to the database.
Error: could not connect to server: Permission denied
Is the server running on host localhost and accepting
TCP/IP connections on port 5432?
Is your database installed and up and running?
Do you have the correct username and password selected in localconfig?
And there is an AVC denial as well:
type=AVC msg=audit(1225832104.970:405): avc: denied { connect } for
pid=30831 comm=index.cgi
scontext=user_u:system_r:httpd_sys_script_t:s0
tcontext=user_u:system_r:httpd_sys_script_t:s0 tclass=tcp_socket
Here is the module I added:
module local 1.0;
require {
type httpd_sys_script_t;
class tcp_socket setopt;
}
#= httpd_sys_script_t ==
allow httpd_sys_script_t self:tcp_socket setopt;
[EMAIL PROTECTED] selinux]#
httpd_sys_script_t ==
allow httpd_sys_script_t self:tcp_socket setopt;
I've tried running the AVC denial message through audit2allow again,
but it just produced the same module that I already have loaded.
Any suggestions?

Dear Sean,
No, there isn't. You'd have to parse the df output to get that

with multi-line output per filesystem.
The following will return kilobytes of disk space used (third column
in the df -kP output):
df -kP |grep -v ^Filesystem |awk '{sum += $3} END { print sum; } '

Re: [CentOS] CentOS 5.2 -- how do I choose a wireless network?
Any suggestions on how to make this work under CentOS? I'd prefer to have CentOS on my laptop, to keep it the same OS as our servers.I don't want to learn two flavors of Linux... Thanks, -at ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] how to install BackupPC on CentOS 5.2 -- use Testing repository
Hi. I just installed CentOS for the first time, to make a BackupPC server. However, when I try to install BackupPC using yum, I get the error: No package backuppc available. I searched the Testing, Extras and CentOS Plus repositories, and found a BackupPC package only in Testing, at http://dev.centos.org/centos/5/testing/x86_64/RPMS/backuppc-3.1.0-1.el5.centos.x86_64.rpm which I downloaded directly. Just posting this in case somebody else has a similar issue. Best, Aleksey ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Re: how to install BackupPC on CentOS 5.2 -- how do I use Test repository?
Ok, downloading the BackupPC RPM directly did not work to myriad dependencies and sub-dependencies. How do I add the Test repository to my yum config, please?

Re: [CentOS] how to install BackupPC on CentOS 5.2 -- use Testing repository
What's a protect base? I added the Test repository to my yum.conf and then I was able to just yum it in. I bet you already had the Test repository in your yum config, dnk. Thanks for your reply! Aleksey Here is what I added to /etc/yum.conf: [c5-testing] name=CentOS-5 Testing baseurl=http://dev.centos.org/centos/5/testing/x86_64 enabled=1 On 7/31/08, dnk [EMAIL PROTECTED] wrote: Do you have any sort of protect base installed?

[CentOS] BackupPC 3.1.0 on CentOS 5.2 triggers SE Linux denial
Hi. I've installed BackupPC 3.1.0 from Testing repository, to Cent
OS 5.2 x86_64, and I am hitting an SE Linux denial - the httpd cannot
talk to the BackupPC socket:
type=AVC msg=audit(07/31/2008 17:18:53.623:410) : avc: denied {
connectto } for pid=11767 comm=httpd
path=/var/log/BackupPC/BackupPC.sock
scontext=user_u:system_r:httpd_t:s0
tcontext=user_u:system_r:initrc_t:s0 tclass=unix_stream_socket
type=AVC msg=audit(07/31/2008 17:18:53.623:410) : avc: denied {
write } for pid=11767 comm=httpd name=BackupPC.sock dev=md0
ino=39813253 scontext=user_u:system_r:httpd_t:s0
tcontext=user_u:object_r:var_log_t:s0 tclass=sock_file
Is there an easy way to fix this, like setting the BackupPC.sock file
universally writeable? I don't know SE Linux and right now my
objective is to get BackupPC up and running.
I've turned SE Linux off for now, but that's temporary until I get a
more targeted fix.
Thanks,
Aleksey

Re: [CentOS] Remounting a USB flash drive
Yes. mount diskid where diskid is your disk device id, e.g. /dev/sdg1 You can find out what it is by running mount while the disk is mounted, or by checking /var/log/messages, to see what disk ID was assigned to it when the device was first plugged in. You might need to specify a mount-point (where the device should be mounted), e.g. : mount /dev/sdg1 /media/flashdrive Hope this helps, Aleksey On 7/31/08, MHR [EMAIL PROTECTED] wrote: I've noticed that once I right click on my flash drive icon and umount it, in order to remount it I have to unplug it and then plug it back in. Is there a command that will accomplish the same task without the unplug and plug back in physics?
