Description of problem:
[root@wolff bruno]# sealert -l 34e7d796-b147-4deb-9455-a3f021d8f328
SELinux is preventing /usr/sbin/arping from using the setcap access on a process.

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

If you believe that arping should be allowed setcap access on processes labeled netutils_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep arping /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
