You must use Python 1.5.2-24 or later with Secure Sockets Layer (SSL) support. If not, the infor-
mation you transfer will not be encrypted. If you have an earlier version of Python, you will see the
message shown in Figure 5-2. To determine the version of Python on your system, use the command
rpm -q python. It is strongly recommended you use Python 1.5.2-24 or later.

If you have already registered your system and try to register it again, the dialog box shown in
Figure 5-3 will appear. If you continue, it will overwrite your existing Digital Certificate file
(/etc/sysconfig/rhn/systemid), and you will create a different System Profile. You will no
longer be able to use your previous System Profile — be sure this is what you want to do before you
choose Yes.
If you overwrite an existing system registration, you can delete the unused profile via the website at
https://rhn.redhat.com.
