Description Fabian Affolter 2010-04-09 18:11:59 EDT

SELinux is preventing /usr/bin/python "getattr" access on /usr/bin/certmaster.

Detailed Description:

SELinux denied access requested by cobblerd. It is not expected that this access
is required by cobblerd 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

allow cobblerd_t certmaster_exec_t:file getattr;
Comment 1 Daniel Walsh 2010-04-11 08:21:19 EDT
Does cobblerd actually need to execute certmaster?
