any significant differences between centos and OEL?
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

why no centos 5.3 or 5.4 online manuals?
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

what is the centos/elrepo policy toward LTS kernels?
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

centos courseware?
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.

dm-crypt/LUKS the state of the art for block device encryption?
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.

RHEL, centos and seeing if i now understand this
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

possible additional comment regarding newer PHP
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

can i run NFS *exclusively* off of v4?
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

should trixbox system hang when ISP drops connection?
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

suggestion for HOWTO: bonding multiple NICs
a student in my RHEL admin class this week specifically asked how to use multiple NICs to add fault tolerance. a good question, i thought. perhaps adding a short HOWTO on that wouldn't be out of line, something like this: http://www.how2centos.com/how-to-set-up-network-bonding-with-centos-5x/ i could even add that as a lab for future classes, where i simply add two USB network adapters to

couple questions about initrd.img
here's hoping this is on topic. as part of the extra goodies i'm going to give my RHEL/centos basic admin class this week, i'm going to get them to open up the standard initrd.img file and see what's inside. i just did that myself and have a couple simple questions. first, while the cpio archive physically contains a number of basic /dev special files, the top-level

does ssh-copy-id not use "id_rsa.pub" file by default?
yesterday, i was demoing how to use ssh-copy-id on centos 5.5 to copy one's public key to another machine and account so you don't need to type the password anymore. i used "ssh-keygen" to create the standard RSA-format files, then checked the man page for ssh-copy-id, which reads: ssh-copy-id [-i [identity_file]] [user@]machine ... If the -i option is given then

the ongoing wait for centos 5.4
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!'.

should i (theoretically) be able to boot a "git clone"d kernel on 5.5?
toward the end of a class on friday, just for fun, i showed the students how to install git, clone the latest kernel source, and build and install a new kernel. since it was getting close to end of day, i wanted to keep it simple and directed them to just "make defconfig" to see what would happen. the configuration and build of the kernel and modules worked fine, they installed the

looking for cool, post-install things to do on a centos 5.5 system
(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,

why does automounting removable media always have options nodev, noexec, nosuid?
i'm experimenting with some basic removable media mounting exercises for an upcoming class, and i read that, while you can use gconf-editor to change some of the mount options in cases like that, there is no way to override the mount options of nodev, noexec and nosuid. for example, that claim is made here (admittedly for fedora, but it appears to be true for centos as well):

where is MySQL-zrm-client rpm package?
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

how to build a centos kernel?
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 --

xen vs kvm for virtualization on centos/rhel?
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
