Ha I didn't realise that ... So there's no way to test if RHN Proxy is
suitable or not ? Doesn't CentOS have a RHN Proxy configured for CentOS
yum servers ?
No. CentOS uses proper Yum repositories. In the old days, CentOS 4
replaced up2date with Yum. Now RHEL5 also uses Yum for package management.
RHN Proxy actually speaks roughly the same protocol for RHEL3/4/5, but
on RHEL5, rather than using the up2date client, yum has something called
rhn-plugin which translates the RHN api to something Yum understands.
What you'll notice is that on RHEL5, /etc/yum.repos.d/ is pretty much
empty - and definitely doesn't contain information about the RHN
Channels you are subscribed to. On CentOS /etc/yum.repos.d/ will list
the repositories for your updates.
To do what you want, you have a couple of options:
1) Configure your own Yum repository(s) and populate it with RHEL
updates (google for this, there are people who have done it before).
http://dag.wieers.com/ has some good tools for creating and updating Yum
repos - I think Dag also provides a method to download updates from RHN.
You then need to retrofit Yum to your rhel4 and rhel3 hosts...
2) Buy RHN Proxy - this will definitely work and is supported by Red Hat.
We use both - we have an RHN proxy for updates, but we also have some
Yum repositories (to make installations faster and reduce reliance on
RHN for installs) - for you RHN Proxy sounds a good fit.
