Summary: SELinux is preventing /usr/bin/perl "getattr" access on /usr/bin/lpstat.cups. Detailed Description: SELinux denied access requested by lpstat. It is not expected that this access is required by lpstat 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.

We have a policy for munin plugins in F13 that allows it. I will backport this policy to F12. You can add a custom local module for now # cat > mymunin.te << _EOF policy_module(mymunin, 1.0) require { type munin_t; } lpd_exec_lpr(munin_t) _EOF # make -f /usr/share/selinux/devel/Makefile # semodule -i mymunin.pp
