similar to: is qemu-kvm really searched for in /usr/bin for KVM?

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 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

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

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

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.

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

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.

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

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

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

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 --

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!'.

just to fix obvious and trivial typoes that i'm running across, like on this page: http://wiki.centos.org/FAQ/CentOS5 "notwithin" "you did not chose to reserve" simple stuff like that. anything more involved, i'll post. rday -- ======================================================================== Robert P. J. Day Waterloo,

absolutely serious question -- i appreciate that it's important to still document how things are done in centos 4, but i have precisely zero interest in that. given how long centos 5 has been out, and that centos 6 is not that far down the road given the alleged release schedule for RHEL 6 (rumoured end of year), i plan on investing my time in centos 5 and 6 exclusively. so while i'm

here: http://wiki.centos.org/HowTos/Network/SecuringSSH the recipe for how to copy your id_rsa.pub file to a remote system is given as: "Copy the public key (id_rsa.pub) to the server and install it to the authorized_keys list: $ cat id_rsa.pub >> ~/.ssh/authorized_keys" i suspect it would be better if that were rewritten in terms of using ssh-copy-id, just to be simpler and
