Description Aleksander Morgado 2011-04-28 21:53:17 UTC
SELinux is preventing /usr/sbin/pppd from 'write' accesses on the file ppp0.pid.

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

If you believe that pppd should be allowed write access on the ppp0.pid 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

Comment 1 Miroslav Grepl 2011-04-29 05:39:46 UTC
The pid file is mislabeled. Did you run pppd directly. I mean without using a service script.

You need to run restorecon

# restorecon -R -v /var/run/ppp*

Will fix.
