Question about differences in RHEL 4.1 and CentOS 4.1 organization. Does CentOS follows same organization as RHEL? I don't see separate directory for 4.1 on Red Hat's ftp server (well, the public part of it, with SRPM packages), seems like all the updates were simply dumped into the 4.0 updates area, so basically doing normal system upgrade will bump all RHEL 4.0 systems to 4.1.
On the other hand, on CentOS site, there is a separate directory for 4.1, with distinct set of packages for 4.1 that are not present in 4.0 update area. So basically, one would need to manually point yum to 4.1 directory tree to fully update system with latest bug fixes.
Is this difference in approach intentional? Or the acutal update process (for those with RHEL subscriptions) is actually like the one for CentOS? How do you determine what packages were "regular" updates, and which packages were part of U1?

As I understand it, this is temporary, and that in a certain amount of time (is there an exact date for this?) the 4.1 tree will replace the 4.0 one.

There is no such thing as RHEL 4.1. Red Hat keeps the version the same and just provides updates. Every so often, a new set of ISOs is spun, and called RHEL 4 Update x (where x increments).

For RHEL, they are all "regular" updates.

For RHEL, they are all "regular" updates.
And for CentOS as well ... the x in 4.x relates to the update number.
There is a 4/ symlink that points to the current tree (4.0) ... the 4/ symlink will shift from 4.0 to 4.1 when all the 4.0 arches (ia64, x86_64, i386) have a fully functional (and tested) 4.1 tree.
We release the Security (RHSA) updates for update X as soon as they come out, then we take the Enhancement (RHEA) updates and Bugfix (RHBA) updates and build the new trees, test them, then release them. When all the trees for the whole release are done, we shift the symlink.
That should happen in the next couple days for both 3.5 and 4.1.
So CentOS 4 is the release and 4.1 means update 1.
So, you can manually point to 4.1 now (if you use ia64 or i386) or wait until we shift the link later after the x86_64 tree is live.
I tried to explain in the availability announcement: http://lists.centos.org/pipermail/centos-announce/2005-June/000310.html
(maybe not such a good job of explaining) :)

Does it mean that if I installed CentOS 4.0, I have to do a yum upgrade on the 4.0 tree in order to have the last version of all installed packages then a yum upgrade on the 4.1 tree ? Or is it possible to do a yum upgrade directly on the 4.1 tree and it will upgrade all the installed packages ?
If it is the first question which list the correct steps, how are made the updates if I install after a period a package from my CentOS 4.0 iso and then do a yum upgrade on the 4.1 tree? (Perhaps that there was an update in the 4.0 updates tree. Or do I miss something?)
One more question : Is it better to do yum update or yum upgrade if I want only the already installed packages to be updated ?
Thank you for your help,
Jean LEE.

update. Using upgrade may replace obsoleted packages with their replacements.

If you install 4.0 and regularly 'yum update' your systems, it will automatically move from 4.0 to 4.1 to 4.2 to 4.3 to 4.x, as they are released. There is no manual intervention required from your side for this purpose.

Hello all,
I 'm new in CentOS 4. I was working before with WBEL 3.0 but I think that I was hacked (I'm not sure) so I install a new server.
I want now to be as secure as possible :
- I disabled every services and the command netstat -taupn returns nothing.
- I setup a firewall with iptables which allows only related and established connections to the intrenal LAN. I'm sure of this firewall. Is it better to use ip6tables ?
- I will now update this server. I want to use yum. Where are placed the CentOS mirrors ( I need it in order to configure yum.conf) ? Is there a way to verify automatically the packages integrity with yum ?
Thank you for your answers

The centos-yumconf package automatically configures yum for you. This package is installed by default.

Yum uses GPG by default to verify the packages.
Hi Jean,
I recognise you from the WBEL list. Hope all is going well with the new reinstalation now. I, too, am new to CentOS.
I've been trying to use yum to perform updates for my freshly installed server and am having problems updating my server using yum. This is the error I keep getting:-
[root@omega]# yum update Setting up Update Process Setting up Repos update 100% |=========================| 951 B 00:00 base 100% |=========================| 1.1 kB 00:00 addons 100% |=========================| 951 B 00:00 extras 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files update : ################################################## 230/230 base : ################################################## 1404/1404 addons : ################################################## 2/2 extras : ################################################## 30/30 Resolving Dependencies --> Populating transaction set with selected packages.

So, I always manually d/load it and update it manually.
Can anyone tell me how to get it working?
Thanks in advance.
Best Regards, Andrew

Because it makes it hard to follow the conversation. Why shouldn't you top post?
Your ISP may very well use one, it wouldn't be the first.
If you can, change your yum repositories from HTTP to FTP and that should fix it. Or, try doing the yum update from a different network.

Cool. Glad to hear you've got a fresh rebuild.

I can understand that.

Wow! Good job! What does this machine do that does not require any network daemons? I usually at least leave SSH up so I can remotely administer the machine.
- I setup a firewall with iptables which allows only related and
established connections to the intrenal LAN. I'm sure of this firewall. Is it better to use ip6tables ?
ip6tables is used for IP version 6. Most of the world has not transitioned over to IPv6 yet (I know I haven't). If you don't know what I'm talking about, you're using IPv4 like the rest of us, which is what iptables is used for.
- I will now update this server. I want to use yum.
Where are placed the CentOS mirrors ( I need it in order to configure yum.conf) ? Is there a way to verify automatically the packages integrity with yum ?
I think someone beat me to answering this question.
