Last modified: 2010-06-23 13:48:48 EDT
Summary: SELinux is preventing /bin/bash "signal" access . Detailed Description: SELinux denied access requested by ifdown-eth. It is not expected that this access is required by ifdown-eth 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.
