Summary: SELinux is preventing /bin/bash "write" access . Detailed Description: SELinux denied access requested by dhclient-script. It is not expected that this access is required by dhclient-script 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.

Paul, looks like the bug #562338. We added a new boolean dhcpc_exec_iptables So just try to execute setsebool -P dhcpc_exec_iptables 1 Should fix for you.
