I don't think up2date has been used since RHEL4 or thereabouts. It basically got replaced with yum.

As btmiller said, yum is a replacement for up2date as of RHEL5, (but it was backported to later versions of RHEL4; v4.7 iirc).
RHEL4 is on Extended life support https://access.redhat.com/site/suppo...pdates/errata/, so go with the latest RHEL6.5 if possible and in any case don't worry about it.
Whatever is the default for your system, it will be part of the std install.

Thanks btmiller and Chrism01..

I needed to know this because I'm planning to deploy update server in my environment. But I'm getting confused as I'm not very much clear about what exactly a RHN Satellite server or RHN proxy will do? I know about YUM and I can use it to update systems but I don't ant to give internet access to all the systems. So I'll deploy an update server ( Planning to use spacewalk.). But I'm nogt clear on exactly how it functions. Is it an replacement to YUM server?

the difference
About 9 years

as above
there is NO choice
up2date died with RHEL 4.5
yum was backported to rhel4.5

and RHEL4.9 went "End of Production 3" in Feb of 2012
and is on "EXTRA extended life-support" that ends next year

there are basically NO supported operating systems that use it any more
rhel4.9 is in basically medical ICU on a respirator
and 4.5 is not still supported



install RHEL 6.5
buy the required support contract for the number of server installs
( not cheep so talk to redhat sales )
and talk to them about a satellite server for offline updates of the servers in your LAN

or
use CentOS 6.5 and set up your own update server

BUT
if you have to ask questions then buying the redhat support contract will be a VERY GOOD investment
over being your own tech support using CentOS

People are not willing to spend money. So I have to go for CentOS.. And there would be servers with different versions of OS. So single YUM repo would not help. I have to create multiple repos. Different for different versions on OS. And there a lies a problem. So I have to go for update server that serves my purpose. But then I'm still not clear about the concepts of RHN Proxy/satellite/spacewalk. I mean I'm not able to figure out how would I make clients to contact update server to check for updates. Also will i need a YUM server if I deploy different update server?

be warned
CentOS ONLY !!! supports the current minor version
right now that is 5.10 and 6.5

the third party repos STAY UPDATED!!!!!!!!!!
the old and unsupported minor versions are moved to the historical archive "The Vault"
http://vault.centos.org/

and it ONLY!!!!!!! has the cent base and update repos for that minor version
Warning:
they are INCOMPATIBLE!!! with the updated thirdparty repos


Redhat will support older minor versions
this is one of the VERY BIG benefits of the paid for support contract

Basically, RH Proxy means just the Proxy server has internet access and all the rest go through that.

RH Satellite means completely off the net (although you need some method to update it of course).
Spacewalk is basically the free / upstream version of Satellite.

Theoretically you could custom build something using https://code.google.com/p/iredmail/w...Yum_Repository.


HOWEVER, as JohnVV said (and please don't take this the wrong way), if you're asking this sort of qn, you REALLY should come up with the money for one of the RH solns, at least for 1 year, whilst you get yourself up to speed on the technology.
This is not a trivial exercise, especially as you're implying this is for Prod servers, where you cannot afford to mess up.

Thanks Chris.. I'm able to configure local YUM repositories. But then I also want to keep them updated with the latest updates. That is why I was going for spacewalk. Last time I tried to create repositories for RHEL6 and RHEL 5 on same server where host server was RHEL6. RHEL 5 clients were not able to read data from repo as the was some mismatch in the YUM repo configuration file formats. So i think a non-YUM server that handles multiple OS platforms is something i need.
