You might not be able to see and access the entire 4GB on a 32-bit system because part of your system memory (up to 512MB) will be reserved for periperal use.

Funnily enough it's only KDE3 that doesn't accept my self-compiled kernels. With Gnome I can suspend and hibernate from the System menu while KDE3 doesn't offer me any option to do so. This means there must be something compiled into these kernels, or some option ticked or not ticked, that makes KDE3 realize it's capable of suspending and hibernating. I'll try the wireless module next. Could you tell me what exactly is different about a realtime kernel compared to a non-realtime kernel? Is it just the scheduling?

Sorry, it's not at all clear to me. The machine in question is running all the time. Are you saying that anacron should be turned off in this case, presumably by "chkconfig anacron off"? 1) I didn't turn it on, so presumably anacron runs by default under CentOS. 2) As far as I can tell, the duplication only started recently, when I noticed that I was getting logwatch messages twice a day. I have another CentOS-5.4 machine, which is also running all the time, and as far as I can see there is no duplication on that machine. To repeat my question, is one meant to turn anacron off if the machine is running all the time? Or is anacron meant to determine this in some way? And if so, how? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I read about that on libvirt.org but chose not to make any changes since the Xen server already works with the same config I have on the KVM server. I understood libvirt to be a layer that lets one compatible tool work with many different hypervisors, so I didn't think I'd need to change my libvirt config to work with KVM if it already works with Xen.

So in this case cron could not perform tasks like logwatch. logwatch will miss in such a case, *if* there wouldn't be anacron which takes over the task to run after the machine is up again (i.e. at 05:00am). There is no need to deactivate or remove anacron. If your system runs all the time, then anacron will not come into play. If you got actions by anacron on one of your systems, then it either was off while cronjobs should have run or it was in single user mode. How anacron handles jobs is documentend in "man 8 anacron". It uses timestamp files in /var/spool/anacron/ to control, when a job was last performed and whether it is pending.

But you only need one or the other. Generally cron on a 24x7 machine and anacron on a laptop. One or the otrher is mormally disabled. cron is a fixed time schedular. I wakes up every minute and checks if there are any jobs to be run. It checks /etc'/crontab for system crons to run and also in /var/spool/cron for individual crons to be run. e.g from my /etc/crontab file 22 4 * * 0 root run-parts /etc/cron.weekly says At 22 minutes past 4am run /etc/cron.weekly anacron is for machines that are not up 24x7 so they could miss some of the times when "cron jobs" were to be run. So anacron wakes up and checks the /etc/anacrontab file. Then it runs any jobs after a certain delay period ( not at a fixed time ) e.g from my /etc/anacrontab file 7 20 cron.weekly nice run-parts /etc/cron.weekly says 20 minutes after waking up every 7 days run /etc/cron.weekly Hope this helps, Tony -- Chief Technical Officer.

Ooops, indeed, sorry for that :-) That leaves, at least, two possibilities 1) the BMC is flaky (power cycle machine or maybe even replace the BMC) 2) kernel driver messed up. If it's the driver then, assuming you havn't already, try to unload the ipmi stuff. Essentially "lsmod | grep ipmi" and the rmmod those. A "service ipmi restart" should probably automate this for you. Since you're focusing on the "in system" approach I assume you lack an ethernet connection to the BMC? ...if not try to reach it that way. /Peter > The > server's still up, though I haven't been into the data center to see if the > idiot red led "fault light" is blinking on (and that has no blink code, > just "there's a problem" is what the docs say). > > mark signature.asc Description: This is a digitally signed message part. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thanks for your response. Actually, I wouldn't mind in the slightest if cron.daily failed to run because the machine was down at the nominated time. It is not as though my world depends on cron.daily running every day. I certainly would not run another program in case that happened. > How anacron handles jobs is documentend in "man 8 anacron".

It says "Anacron records the date in a special timestamp file", but it doesn't say where that file is. I see that there are actually files /var/spool/anacron/cron.daily , etc, on my machine listing the last day anacron ran (20100311) But it seems that this information is not used, in my case, I don't know why. As I said, this duplication seems to have started recently, and I have taken no action on this machine for months apart from running "sudo yum update", so I assume some update had this effect.

[CentOS] drbd-kmdl packages question
Dear collegues!
I've got one question about drbd-kmdl packages.
As I can see at
$ rpm -qp --qf "%{DESCRIPTION}" kmod-drbd-8.0.16-5.el5_3.i686.rpm
This package provides the drbd kernel modules built for the Linux
kernel 2.6.18-128.4.1.el5 for the i686 family of processors.
So, the question is - kmod-drbd is for kernel 128.4.1 (or build for this
kernel version), but current kernel is 164.11.1. Does that means that
kmod-drbd should be rebuild for each kernel or it works vell without
rebuild?

No, it is a kernel version independent, kABI-tracking kernel module.
So, it should survive each kernel update. No need for rebuilding. (It
is different from drbd-kmdl)

In fact, it's not that simple; anacron isn't a persistent daemon.
The way it works is that the rc script calls anacron to catch up on
missed jobs. When anacron has finished this then it exits.
Now from regular cron you'll see /etc/cron.{daily,weekly,monthly}/0anacron
which calls "anacron -u". This simply tells anacron to update the
timestamp and does nothing else.
And that's how the boot version determines if there's work to do; if the
timestamp file is too old at boot time.
During normal operation anacron shouldn't run (except for the timestamp
updates). If it is then either it's been running since boot time
(lots of work to catchup? hung?) or else it's been incorrectly started.
So
$ chkconfig --list anacron
anacron 0:off 1:off 2:on3:on4:on5:on6:off
$ service anacron status
anacron is stopped
$ grep anacron /var/log/cron

Re: [CentOS] Kernel Panic with wl.ko (Broadcom wireless driver) [CentOS 5.4]
Bad news. Just like my self-compiled 2.6.25 and 2.6.27 kernels my laptop froze with your kernel and the wl.ko module, too. It didn't kernel panic and it lasted significantly longer than with 2.6.18 but it still froze in the end. I'm back to 2.6.18-164-11-bug4139.4192.4196 now. Instead of Broadcom's proprietary wl.ko module I'm now using bcm43xx with an extracted Broadcom firmware that I extracted via b43-fwcutter. That one has been running perfectly fine for the entire day now without freezing, crashing, or anything. And both standby and hibernation seem to work just fine.

Thanks a lot Rex. I had to delete wicd again because it failed to save my password too. It actually saved the wrong password - for whatever reason it was stored something completely different not even remotely similar to my WPA key. I'll try that workaround next.

I just wanted to let you know (in case you are not aware) that the kernel 2.6.18-164-11-bug4139.4192.4196 is a test base for the centosplus kernel. When the next kernel update comes out, it will be "promoted" to the official cplus kernel. If you would like to continue using this kernel, please be sure to configure your .repo appropriately ( http://wiki.centos.org/AdditionalResources/Repositories/CentOSPlus ).

In that case feel free to disable anacron, but it really makes little
difference. As Stephen has pointed out, in CentOS 5 anacron runs once
when you enter any of the runlevels where it is active, runs any
overdue {daily,weekly,monthly} jobs, and then exits. If there are no
overdue jobs, anacron exits immediately.
BTW, don't try to apply this knowledge to more recent releases, such
as Fedora 12. There, the interaction between cron and anacron is
more complex. The standard setup there is for cron to run only the
hourly jobs and for anacron, started each hour as one of those jobs,
to run any needed {daily,weekly,monthly} jobs.

The machine stops and then starts again (if it doesn't then it doesn't matter whether anacron is running or not). In my experience the probability of this occurring is close to zero, and it wouldn't really matter if logrotate or something like that was put off for one night. What are you running through cron.daily on your 10's of servers that is so vital? >> I see that there are actually files /var/spool/anacron/cron.daily , etc, >> on my machine listing the last day anacron ran (20100311) >> But it seems that this information is not used, in my case, >> I don't know why. ... >> As I said, this duplication seems to have started recently, >> and I have taken no action on this machine for months >> apart from running "sudo yum update", >> so I assume some update had this effect. > On my laptop > > # rpm -qa --last | grep anacron > gives > cronie-anacron-1.4.3-4.fc12 Sat Feb 27 11:05:52 2010 In my case, [...@helen ~]$ rpm -qa --last | grep anacron anacron-2.3-45.el5.centos Fri 07 Mar 2008 08:36:23 PM GMT Note the year (2008). It seems anacron has not been updated for ages, although I run "yum update" every day. I'll try turning off anacron on the first machine, and see what happens. The duplication issue is not really a problem - I just wondered (and wonder) why it is happening. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

On one machine at least it must have been running since CentOS was installed. > By the way I run centos on several of my laptops and they're not up 24x7 Seems a strange distribution to me to run on a laptop. Don't you find you are missing some things? In any case, surely CentOS is intended basically for servers, which are unlikely to be turned off very often? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

That's how the "Internet Worm" spread.
As a general principle, machines on the "periphery" or what one
might call "firewall machines" should have nothing installed
which they don't need in order to perform their primary intended
function. That means both hardware and software, IMO.
The less which is there, the fewer potentials for compromise exist.
No services should run which aren't necessary for the functioning
of the machine. Don't even install them unless you have to, but
don't enable/start them if you install them.
I would install rkhunter and tripwire, and I would peruse their
logs.
