Description Jeff MacDonald 2011-05-30 13:31:20 UTC
SELinux is preventing /sbin/dhclient from 'read' accesses on the file dhclient-br0.pid.

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

If you believe that dhclient should be allowed read access on the dhclient-br0.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 dhclient /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-05-30 13:40:29 UTC
Execute

# restorecon -R -v /var/run/dhclient-br0.pid

will fix. Please reopen if this happens again. Thank you.
