similar to: another small glitch regarding 3rd party repos -- samba sernet link broken

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."

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.

a couple folks on the local mailing list were asking about the mechanics of building a kernel for a centos system, and they seemed to suggest that there were some intricacies involved as opposed to other distros. i've never tried it -- is there a trick or something? got a pointer to the canonical web page that has the directions? thanks. rday --

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!'.

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

i may be in the position of recommending that a sizable client take a look at centos as a supported platform in the near future, but if one goes to the "Support" -> "Commercial Support" page, it reads: This Section or Page is coming soon. that is *not* going to give this client any warm fuzzies. from a promotion perspective, either that page should get some actual

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

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

it's all about the open source, baby. http://candyandaspirin.blogspot.com/2009/09/next-adventure-in-ecm-begins.html DISCLAIMER: the lady in question is a good friend of mine. but don't let that scare you off. :-) rday -- ======================================================================== Robert P.

what is the proper approach to install on centos 5.4 a package that's newer than the currently supported one? at the moment, AFAICT, the latest "poppler-utils" package for centos is 0.5.4. however, the source is up to version 0.12: http://poppler.freedesktop.org/ which matches the current fedora version, but that's not surprising since, naturally, fedora zips right along

being used to mysql 5.1 on my fedora system, i'm suddenly looking after a centos 5.4 box with mysql 5.0.77. before i start digging into the mysql 5.0-5.1 changelog, do i have a lot to worry about in terms of mentally backing up one version? or is simply upgrading the centos box to mysql 5.1 an option? (i realize that mysql 5.1 is *not* officially supported in centos 5.4.) rday --

perhaps an open-ended request, but i'm looking for (if it even exists) some centos 5.4 software that will let me completely simulate the sending and reception of MMS messages on a local network which (AFAICT) would require the simulation of the MMS centre as well (MMSC). so far, i've run across (yum-installable) gammu and i'm just starting to take a look at it. but if anyone out

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.

just to follow on my earlier post, i have pointers to a couple commercial C/W manuals for RHEL administration, but both of them use an entire chapter discussing virtualization using Xen. i'm under the impression that RH is firmly in the KVM camp (at least for now), and that learning Xen on red hat/centos wouldn't be as useful as learning KVM. thoughts? rday --

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

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
