Description Wolfgang Rupprecht 2013-08-07 10:55:54 EDT
Description of problem:
this happened when I enabled ipv6 pings in smokeping.

*** Probes ***


 binary = /usr/sbin/fping6 


*** Targets ***

 probe = FPing6 

see: http://oss.oetiker.ch/smokeping/probe/FPing6.en.html

SELinux is preventing /usr/bin/perl from using the 'signal' accesses on a process.

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

If you believe that perl should be allowed signal access on processes labeled smokeping_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 perl /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
