Description Professor W P Jones 2013-01-31 10:53:02 UTC 
User-Agent:       Mozilla/5.0 (X11; Linux i686 on x86_64; rv:14.0) Gecko/20100101 Firefox/14.0.1
Build Identifier: 

Detailed Description:

SELinux denied access requested by ip. It is not expected that this access is
required by ip 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 ./net,

restorecon -v './net'

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.
