This system is not registered with RHN.

Perhaps you should either register or use a free (as in beer) RHEL clone like Scientific Linux or CentOS?

You could change your yum configuration to look for updates in the CentOS and related repositories.

[scathefire]

the first error was you did the command wrong, should be:

yum install packagename

the second error is an obvious failure to resolve a name. Perhaps you should try:

/etc/yum.repos.d/rpmforge.repo
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge

When you use 3rd party repositories, it is highly recommended that you also use yum-priorities.

base, plugins, updates should be given like 1 or 2. third party repos like rpmforge should be assigned a number like 10, to keep package overlapping from occuring

for you install apache as below

yum install httpd*


it should take you to repositories as mentioned in /etc/yum.repos/***.repo
