Red Hat NETWORK SATELLITE 5.2 - CLIENT Configuration Manual page 32

Chapter 6. Manually Scripting the Configuration
This script comprises a clean and repeatable process that should fully configure any potential Red
Hat Network client in preparation for registration to an RHN Proxy Server or RHN Satellite Server.
Remember, key values, such as the URL of your RHN Server, its public directory, and your actual
GPG key must be inserted into the placeholders listed within the script. Also, depending on your
environment, additional modifications may be required. Although this script may work nearly verbatim,
it should be used as a guide.
Like its components, this script may be centrally located. By placing this script in the /pub/ directory
of the server, running wget -O- on it, and piping the output to a shell session, one may run the entire
bootstrap process with a single command from each client:
wget -O - http://proxy-or-sat.example.com.com/pub/bootstrap_script | bash
Warning
Running a shell script directly from input piped in over a Web connection obviously has
some inherent security risks. Therefore, it is vital to ensure the security of the source
server in this instance.
This one-line command may then be invoked across all of the systems on a network. If the
administrator has SSH access to all of the systems in question, it would be a simple task to iterate
over a list of these systems and run the command remotely on all of them. This script would also be a
perfect addition to the %post section of an existing kickstart script.
