Hello!

I am new to this forum.
I have the pirated redhat 5 in my notebook. Now I need to do yum configuration. But for this we need the baseurl.
I don't know the baseurls for downloading some important packages.

So please help me.

No such thing - read the license terms. you are entitled to copy, distribute, modify and distribute modified copies of the software covered by GNU GPL. The only way you can steal from free software is if you distribute a modified copy under incompatible terms.

We try to avoid using the propaganda term "pirate" in connection with copyright infringement since it risks equating normal social sharing with activities properly associated with stealing ships.
RHEL is a commercial distro - to gain access to the RHN yum repos, you are expected to pay for a support contract with Redhat.

If you do not want to do this, then you should change to a non-commercial distro. The closest to RHEL is CentOS (it is software-identical, only the pictures are different).

Technically you could support RHEL by hand, or using repos from fedora or centos - but this is not recommended.

You are encouraged to support free software companies by purchasing their services or support community distributions by contributing to their knowledge-base as a user or more.

why you are using Redhat than??? you should go for CentOS 5.x, its absolutely free, its 99.99% same as RedHat, and there are number of freely available mirrors for Centos updates, so i suggest you to not using RedHat if you are not using RHN.

There are a number of reasons someone may feel they must use RHEL but are unable to pay for RHN support. As you point out, they are almost always better off with CentOS.

OP use of the word "pirate" suggests that there are deeper issues - it is a sign of someone who has bought into a lot of the marketing stuff that infects the proprietary markets. Myths like: "pro" or "commercial" editions are better than the others. Like "copyright infringement is theft".
