similar to: how to build a centos kernel?

does anyone here have pointers or access to courseware that could be used to teach centos (5.4, i believe)? publicly-available, free C/W would, of course, be ideal, but if you have some decent training manuals that you're willing to license on a per-manual basis, i'm still willing to chat. rday -- ======================================================================== Robert P.

it's been a while since i've played with filesystem encryption so, on centos 5.4 (and other linux distros), is dm-crypt/LUKS considered to be the state of the art WRT encryption? i remember other solutions like loop-aes and others, but what's considered the gold standard these days? rday -- ======================================================================== Robert P.

ok, given the flurry of responses to my original post, let me see if i have a handle on this as i think i've finally figured it out and, yes, it does make sense. the scenario is that there is a very large software company in the area whose only officially supported linux platform is currently suse. however, they are getting increasing call to have their product run on red hat. for most

someone just pointed out to me that there is a distro called "oracle enterprise linux" which is effectively a re-branded RHEL, so i'm curious -- has anyone here used both centos and OEL and would there be any differences that would be worth caring about? the only thing i can think of that might be worthwhile is that OEL might change some of the default kernel parms thru

at the risk of picking at that scab a bit longer, i'm going to toss out a comment regarding people still waiting for the public availability of centos 5.4. here: http://lists.centos.org/pipermail/centos/2009-October/083743.html we read: "The last status (from twitter) is 2 days old with the '5.4 is baked! centos internal network will start syncing up today. Release ~ soon!'.

i'm reading the lowdown on 3rd party repos with respect to centos here: http://wiki.centos.org/AdditionalResources/Repositories and i have a couple questions and observations. first, the entry for centosplus reads: "Popular packages from this repository include: postfix with database support, a rebuilt kernel with additional drivers & filesystem support, php5 and mysql5."

i'm just curious -- how many people here are using ACLs as a regular and significant part of their sys admin? rday -- ======================================================================== Robert P.

NEWBIE alert: i'm a linux person, not an asterisk person so i'm certainly capable of handling any linux-flavoured solution you can suggest. here's a note i got from a local company i know (some proper names removed): ===== start ===== Now and again our ISP goes down and when it does give us a hicup, the Asterisk system shuts down (not very forgiving). When it shuts down our phone

i zipped over to centos.org to check out the 5.4 manuals, and what i found was: http://www.centos.org/docs/5/ which stops at 5.2. now, i don't really see this as a problem since i can always get what i need here: http://www.redhat.com/docs/manuals/enterprise/ i'm just curious as to whether centos is just not bothering to rebrand the manuals since it's just as easy to get that info

i was looking at options for backing up mysql databases across the net, and ran across this: http://www.zmanda.com/download-zrm.php clearly, there are two rpms for linux: * MySQL-zrm-2.2.0-1.noarch.rpm * MySQL-zrm-client-2.2.0-1.noarch.rpm but on a centos 5.4 system, if i do # yum search zrm i see only "MySQL-zrm.noarch". anyone know why the centos repo would only know about

again, from here: http://wiki.centos.org/FAQ/CentOS5 regarding a newer version of PHP, a number of PHP experts that i know of suggest that, if you truly need an up-to-date version of PHP, you should: rpm -ivh http://rpms/famillecollet.com/enterprise/remi-release-5.rpm while remi collet's repo isn't official, it's accepted by numerous developers as a reliable source of newer PHP

i'm prepping to teach a 5-day intro class in linux starting in about 3 hours, and the courseware is clearly designed around RHEL (apparently 5.1). but since i'm not being provided with RHEL DVDs, i'm just going to hand everyone a centos 5.4 DVD and take it from there. as part of the intro, i want to briefly discuss the varieties of linux related to RHEL, so obviously i want to

is it possible to set up NFS on centos 5.5 so that it uses *only* version 4? i tried this not that long ago on fedora and was surprised to see a complaint when i tried to start the server and was told that i was missing required functionality of NFSv1, or something equally weird. i'll check the /etc/init.d/nfs script, but i think what got me into trouble was trying to use the entire set of

i'm sure there's a simple answer to this -- i already understand that newer kernels than the ones shipped with the official release aren't officially supported but there is the elrepo kernel repository here: http://elrepo.org/linux/kernel/el7/x86_64/RPMS/ with a mixture of long-term (lt) and mainline (ml) kernels. i assume that the mainline kernels pretty closely track the latest

Dear Centos community, I am new to centos/redhat and I would like to know on a centos system, can I use yum alone to do all package management? I don't want to learn two systems and confuse myself, I understand yum is much better than rpm if is the case? Thank you! Jim

any testimonials for some simple wiki software to run on centos 5.4 on an intranet? all i'm after is something uncomplicated that (ideally) yum installs, and that others can start using to start sharing useful info, nothing more. thoughts? rday -- ======================================================================== Robert P.

(note: i asked this a few days ago but it *appears* that that post was tossed due to getting excessive bounces from my account. so i'm posting it again, apologies if you're seeing it a second time.) over the next several weeks, i'm teaching some courses in RHEL admin but (unsurprisingly) i'll be using centos 5.5. it's a decently-written, 3rd party course, all the generic,

as i'm reviewing the courseware for the rhel (centos) course i'm teaching next week, i'm going to ask the occasional question, possibly technical, possibly more policy. first one involves the choice for virtualization. the course has a short section involving virt using xen but everything i've read suggests that red hat is concentrating on kvm for virt. thoughts on that? i

yes, it's OT but just in case folks here know someone who might be interested, i'm writing and publishing a course to introduce people to the joys of linux kernel programming: http://www.crashcourse.ca/introduction-linux-kernel-programming/introduction-linux-kernel-programming and, no, it's not free -- six months worth of course will cost you all of $39 (CAD), but the first four

more a terminology usage question than anything else, but in a couple of weeks, i'll be teaching the first of a few sessions on RHEL admin and, unsurprisingly, i'll be using centos (as i've done in the past). when i asked the organizer to identify the specific version of RHEL that was being used at the client site, i was told 5.3 so i can easily install 5.3 on the classroom
