Section 2.3:Registering a User Account 19
Figure 2–4 Error: Username Already Exists
Note
If you are already a member of redhat.com, you can use the same user name
and password. However, you will still need to continue with the registration
process to create your System Profile.
Your user name and password have the following restrictions:
• Must be at least four characters long
• Are case-insentitive
• Can not contain any spaces
• Can not contain any tabs
• Can not contain any line feeds
• Can not contain the characters &, +, %, or ’
If you have already registered your system and try to register it again, the dialog box shown in Figure
2–5, Warning: This System Already Registered will appear. If you continue, it will overwrite your ex-
isting systemid 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 .
