------------A snip from the logwatch included at
end-----------------
Summary:
SELinux is preventing netstat (logwatch_t) "search" to <Unknown>
(sysctl_net_t).
Detailed Description:
SELinux denied access requested by netstat. It is not expected that this
access
is required by netstat 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:
Sometimes labeling problems can cause SELinux denials. You could try to
restore
the default system file context for <Unknown>,
restorecon -v '<Unknown>'
If this does not work, there is currently no automatic way to allow this
access.
Instead, 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.
