The

/var/www/html/pub/bootstrap/bootstrap.sh

Server installation program and available to both Satellite and RHN Proxy Server customers through

the use of RHN Bootstrap provides the ability to reconﬁgure client systems to use the RHN Server

easily. After modifying for your particular use, it can be run on each client machine.

Review the sample and its comments, beginning with a hash mark (#), for additional details. Follow

the steps in Chapter 5 Using RHN Bootstrap to prepare the script for use.

#!/bin/bash

echo "RHN Server Client bootstrap script v3.6"

# This file was autogenerated. Minor manual editing of this script (and

# possibly the client-config-overrides.txt file) may be necessary to complete

# the bootstrap setup. Once customized, the bootstrap script can be triggered

# in one of two ways (the first is preferred):

(1) centrally, from the RHN Server via ssh (i.e., from the

RHN Server):

cd /var/www/html/pub/bootstrap/

cat bootstrap- edited_name

...or...

(2) in a decentalized manner, executed on each client, via wget or curl:

wget -qO- https:// hostname

...or...

curl -Sks https:// hostname

# SECURITY NOTE:

Use of these scripts via the two methods discussed is the most expedient

way to register machines to your RHN Server. Since "wget" is used

throughout the script to download various files, a "Man-in-the-middle"

attack is theoretically possible.

The actual registration process is performed securely via SSL, so the risk

is minimized in a sense. This message merely serves as a warning.

Adminitrators need to appropriately weigh their concern against the

relative security of their internal network.

# PROVISIONING/KICKSTART NOTE:

If provisioning a client, ensure the proper CA SSL public certificate is

configured properly in the post section of your kickstart profiles (the

RHN Satellite or hosted web user interface).

# UP2DATE/RHN_REGISTER VERSIONING NOTE:

This script will not work with very old versions of up2date and

rhn_register.
