system-config-*

I also tried to install system-config-* package through yum but getting the error message that,

cannot open file: system-config-*
cannot open file: system-config-*

Any responce will be appreciated.

Have you installed X window system and some desktop environment like Gnome, KDE, XFCE or other else? If not, then you will not be able to use any package that needs X.
If you have RHEL5, then you can add epel repositories and then install packages you want.
For installing X and desktop

yum groupinstall "X window system"
yum groupinstall KDE

I am getting the message that there is no X window package available.

Thanks

install X

See, you are using RHEL5, which is a paid subscription distribution. You need to pay for the updates, upgrades and using red hat repositories. You will need to add the extra repositories. Please check the EPEL repositories for RHEL5. Add those to yum and update yum and then install the packages. And also give the exact commands that gave you errors and if possible screen shots or images of what you did that produced errors.

The IT managers have create a local repository local.repo:
I don't have de RHN serial number, the It managers don't give it to me and don't make what i need, the server is my responsability, i am the owner of them, but internel politics in my work are made not for users, but for "some people" commodity.

If i install EPEL repo, rpmforge or simply put the centOS repos ... will that work?

The local repository is a local media which could be any optical drive like cd or dvd on your system. And if you do not have that, it would not work. Like said in the earlier posts, you will need to add extra repositories. Read through the thread to understand how to add repos.
