Summary: SELinux is preventing /usr/sbin/pppd "read write" access on noz0. Detailed Description: [pppd has a permissive type (pppd_t). This access was not denied.] SELinux denied access requested by pppd. It is not expected that this access is required by pppd 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.

This access seems to make sense. I was surprised it did not already have it. Miroslav, add dev_rw_modem(pppd_t)
