Description Amit Shah 2011-05-27 09:17:07 UTC
SELinux is preventing /usr/sbin/pppd from 'unlink' accesses on the file LCK..ttyUSB3.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that pppd should be allowed unlink access on the LCK..ttyUSB3 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pppd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
