If you want security updates, you must do either one of two things:
Always update to the latest service pack, currently 5.9.
RHEL subscriptions normally receive security and bug fix updates against the latest minor release only. However, Red Hat does offer backporting:
Purchase Extended Update Support for the specific minor release you want to remain on.

At least for me, yum is bright enough that if I tell it to install something which is already installed, and for which an update is available, it will just apply the update instead. E.g.:
[root@risby ~]# rpm -qa|grep openvpn
openvpn-2.2.2-7.fc17.x86_64
openvpn is installed.
[root@risby ~]# yum update
[...]
--> Running transaction check

You can install Python 3 alongside 2 as long as it's configured to a different folder. Then it's just a matter of pointing your scripts to the proper install of python.

From here it's stated that you can do it, just follow the recipe guide, changing versions accordingly.
From what I recall, CentOS is a rebuild from source of RHEL, and versions are paired. So if you're on RHEL6.3 your upstream mirror would be the CentOs-6-repos.

That code snippit is from GridFTP. gcp simply needs to be available and in your PATH, but those are specific to your site. Most clusters/Grid systems have a special location for the Grid utilities. Contact your cluster admin or your local GridFTP admin for details.

You should be fine. Red hat subreleases are far more flexible than, say, Solaris U# releases. It isn't uncommon to install off a rev like 5.4, run yum update, and then see the redhat-release file suddenly show that you're at RH 5.8 (in fact, it can be kind of troublesome when you need specific file levels to ensure multiple environments are exactly in sync, ...

Since I just spent my entire morning debugging this same issue. Let me explain what happened above.
/etc/auto.master
## Mount this test share:
/test /etc/auto.test --timeout=60
This means I want to mount something at /test and for the details read /etc/auto.test

RHEV is a product sold by Red Hat, run on top of Red Hat Enterprise Linux 6 (as of this writing) and which comes designated as "enterprise-ready". It is ...

I noticed this new workaround in the redhat KB:
Red Hat Enterprise Linux 6.2
Manually Setting a Preferred Operating System Release
Beginning in Red Hat Enterprise Linux 6.3, Red Hat Subscription Manager could set a preferred operating system version to use to limit automatic updates for a system. This is covered in Section 5.7.4, “Setting Preferences for ...

Slow ssh connection / ssh lag is a symptom of a high load. High load is often caused by io blocking, which is often caused by swapping.
to check your load, run uptime or top you will probably see load numbers over 10 when ssh is not responding. They will probably hover under 2 during normal use.
run free or top to see your memory usage, you will probably ...

You're right, you need to use the old "rhnplugin" to talk to RHN Classic or RHN Satellite.
The "Unable to read consumer identity" message is harmless, it's just the "subscription-manager" plugin saying the system isn't registered via RHSM.
You can disable the "subscription-manager" plugin on your clients if you like.

The chkconfig definition at the start of an initscript determines what S/K number it gets.
Each "runlevel" is actually just a directory (/etc/rc*.d/) full of symlinks to initscripts (/etc/init.d/) and those symlinks are named with numbered S and K entries.
S means start and K means kill. When init enters a runlevel, it starts with S01 and works its way ...

CentOS version number basically matches the RHEL version numbering, so you will want to get a copy of CentOS 5.5 from their vault, as the current release in the 5.x line is 5.9.
I don't recall any special settings that are needed for a CentOS guest on VirtualBox, if only to get the thing running. A plain vanilla install should work. You will, of course, ...

Get into the habit of using GNU Screen. Install it with yum install screen.
Screen is a "terminal multiplexer". What does that mean? It's like a terminal within a terminal, which you can leave and come back to.
You start a screen session by running screen. You can have multiple terminals within the one session. You create a new terminal using Ctrl+A then ...

You can do this, but whether you should or not is another matter.
Red Hat will not support packages from third-party sources, including the CentOS repositories.
If you're expecting this system to be supported by Red Hat, then don't add the CentOS repos and update from them, just register the system to RHN.
If you want to use CentOS repositories, then run ...

When running the spacewalk-create-channel command, you get a static channel with packages based on the options you provide. You can always then manually clone or push in packages and security errata from other channels to it, but then you might end up having a hard time keeping track of what's in the channel...
Does that mean a created channels with the ...

I think that python.org has this covered quite nicely on their wiki.
For most part, python 2 is feature frozen, but should be supported for quite a while. A lot of stuff relies on it, and some major software needs it. Python 2 is the status quo, and you are VERY likely to find this on almost any major distro.
Python 3 has a lot of new shiny stuff, and a ...

The auditd(8) daemon provides the functionality you request in your question. It is configured in the /etc/audit/auditd.conf file, and its syntax is described in the auditd.conf(5) manual page.
You need to install and enable the daemon, and configure the /etc/audit/audit.rules to audit those events you consider relevant. And example from the audit.rules(7) ...
