Bug 624440

Summary:

SELinux is preventing /usr/sbin/upsd "connectto" access on
/var/run/nut/usbhid-ups-myups.

Detailed Description:

[upsd has a permissive type (nut_upsd_t). This access was not denied.]

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