Summary:
SELinux is preventing dhclient (dhcpc_t) "read write" unconfined_t.
Detailed Description:
SELinux denied access requested by dhclient. It is not expected that this access
is required by dhclient and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.
Allowing Access:
You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Summary:
SELinux prevented kde4-config from writing .kde.
Detailed Description:
SELinux prevented kde4-config from writing .kde. If .kde is a core file, you may
want to allow this. If .kde is not a core file, this could signal a intrusion
attempt.
Allowing Access:
Changing the "allow_daemons_dump_core" boolean to true will allow this access:
"setsebool -P allow_daemons_dump_core=1."
Fix Command:
setsebool -P allow_daemons_dump_core=1

I appreciate any help I can get. It has been a while since NetworkManager gives me a successfull connection. I have to become root and use dhclient to get internet access. If I need to file bug reports, please let me know against which components and I will do it.
Thanks,
Antonio
