Re: [CentOS] 1333/8GB Intel motherboard for C5.1

Current applications are built to access up to 4Gb RAM at a time only. For machines with RAM of more than 4Gb you need to verify that the CPU comes with Physical Address Extensions (PAE). Call Intel to verify this CPU is with PAE. So, now its the Linux kernel that you need to turn to. CentOS 5.1 64 bit should not have this limitation. However, the following method allows up to 64Gb out of box for CentOS 5.1 32bit (u can try this if the 64bit didnt work out). Do the following in runlevel 3 as root user; # yum install kernel-PAE # reboot # free But all this needs to come with distributed swap and use of appropriate file system type to ensure performance. -- Nicholas A.

Re: [CentOS] 1333/8GB Intel motherboard for C5.1
your 'bug' is issue A).I think its more a design feature or side effect, not an outright bug, but thats a nomenclature thing. Seems like it is the way Intel chips are designed. One solution would be to ensure that 64bit is used. However, due to cost I am sure many would have gone for the 32bit machines with AHCI mode.

Re: [CentOS] is CentOS an LSB certified product?
Herrold, I meant RH, in terms of the RHEL distro. I look forward to have centos gain the LSB, what is needed for the pass thru? is the main CentOS community interested? As for the rest, thank you for the sharing of info. The LSB should be concern to encourage developers to built stuff that can be used across distros. LSB should reduce problems of desktop users who have been finding difficulty in getting stuff like printer drivers and other paraphernalia. The more distros adopting LSB then more developers/manufacturers will be encouraged on the use of LSB.

Re: [CentOS] Re: is CentOS an LSB certified product?
Its not a matter of licensing. Since the days of various Linux distros, coming up with diff schemes made it difficult for developers to target a Linux.

This way when they write software they can be rest assured that if the system is LSB certified that it will contain the 'bash' utility, that utility will be in /usr/bin, man pages will be in /usr/share/man, etc. This way they only have to write 1 set of installation packages and not a separate package for each Linux distribution they wish to develop for. -Ross __ Cool, thanx for the explanation :) I suppose it doesn't change the licensing at all. -- Nicholas A.

I believe that there is a perceived convergence of "needs" between (call it...) more-mobile personal linux and _virtualised_ server linux. If we can create a linux VM in under 5 minutes, "we" expect that it will boot-up without the sys admin's intervention. Then "we" expect that we can migrate it to newer hardware without manual reconfiguration. But returning to PHP: If apps are developed without real separation between user interface and back-end, then the back-end will be victimised by the relative and inherent instability of the front-end. The web servers then really become part of the front-end and must be handled as such. I would argue that this lack of separation between front-end and web server is a feature of the WWW and its protocols, we cannot escape it. So no surprise that most data centers leave the web servers outside or mostly-outside the network perimeter. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] Need firewalld clue
I don't really understand the intent behind firewalld. The RHEL7 Security Guide states "A graphical configuration tool, *firewall-config*, is used to configure firewalld, which in turn uses *iptables tool* to communicate with *Netfilter* in the kernel which implements packet filtering". So is the goal for firewalld to implement a GUI for iptables? What is the "value added" by firewalld?

Re: [CentOS] hostname service?
>The service you are referring to is hostnamed [1]. hostnamed is >designed to start on request and terminate after an idle period. >Programs on your computer are probably querying the service to >determine if your hostname has changed. I see that I couldn't previously find it with systemctl because it is a "static" service, neither enabled nor disabled. What is "static" really intended to mean here? The other static services seem to be boot-time related for the most part, eg anaconda, pvscan Man for hostnamectl (also new to me) indicates some potential uses for the hostnamed-maintained names, yet I see nothing obvious making use of that info. Can you give me an example?

[CentOS] packagekit yumBackend question, perhaps
Periodically I find the yumBackend python script of packagekit really slows down my CentOS 7 system. I don't invoke anything myself which starts it and I find nothing in crontab which does either, except perhaps /etc/cron.hourly/0yum-hourly.cron. But I can't be sure that is the culprit. I don't find anything at http://www.freedesktop.org/software/PackageKit which helps me to debug this. Would someone point me in a useful direction so that I can find out what /usr/share/PackageKit/helpers/yum/yumBackend.py is doing, why it is doing it, and how it can be controlled?

[CentOS] hostname service?
On CentOS 7, I find in /var/log/messages several times daily messages "localhost systemd: Started Hostname Service.". However I can't seem to find such a service using the systemctl command. What is the "Hostname Service", what does it do and why is it being restarted frequently? Many thanksNick ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] nsswitch.conf question
I find the passwd, shadow and group lines in my CentOS 7 /etc/nsswitch.conf file specify "files sss". I'm not familiar with the "sss" source, would someone please give me an idea what that is? Many thanksNick ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] ifenslave vs. /etc/sysconfig/network-scripts
How does the ifenslave command relate to "normal" network slave configuration in /etc/sysconfig/network-scripts? Does config-file-based setup use ifenslave or is it more complicated than that? ThanksNick ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] Cloud image_index: is 1801-01 a release?
I load CentOS cloud images into our infrastructure for our users to use, and I have a script that looks at https://cloud.centos.org/centos/7/images/image-index, picking what has the highest revision, to find the new hotness. Up until the most recent image, they've all appeared in there; is this changing going forward? How can I automatically find the newest one and its revision tag? The untagged "latest" ones (linked to by the https://wiki.centos.org/Download page) don't appear in the sha256sums file, so I couldn't even compare sums. Can I petition for keeping the cloud image-index up-to-date? -- Nick Timkovich | Software Engineer | Computation Institute, University of Chicago | n...@uchicago.edu ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[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?

Re: [CentOS] drbd-kmdl packages question
OK, thank you!
One more question.
Does anyone have the same problem - when installing drbd-kmdl package via
yum, madwifi packages needs to remove. May be I missed something, but I also
need madwifi packages =)

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)
Oh, and yes, that description should be changed to reflect the fact. :-D
Ralph? Are you the dev in charge of the maintenance?
