I've just started using selinux in the last 6 months and am getting to grips with it. However, using sealert on a new CENTOS 6 server, Im not getting the level of detail I was with CENTOS 5. To illustrate:

Running sealert -a /var/log/audit/audit.log

On CENTOS 5 I get:

Summary:

SELinux is preventing postdrop (postfix_postdrop_t) "getattr" to /var/log/httpd/error_log (httpd_log_t).

Detailed Description:

SELinux denied access requested by postdrop. It is not expected that this access is required by postdrop 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 /var/log/httpd/error_log,

restorecon -v '/var/log/httpd/error_log'

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.

but on CENTOS 6 I just get:

Im running exactly the same command. Does anyone have any idea why Im not getting the "Additional information" that I do with CENTOS 5?

Thanks in advance Dylan
