Description Steve Traylen 2010-05-30 16:44:45 UTC
Summary:

SELinux is preventing /usr/lib64/nagios/plugins/check_ping "sigkill" access .

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

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