Description Till Maas 2012-12-14 17:08:14 UTC
Description of problem:
This happened after I installed munin-cgi and started httpd.
SELinux is preventing /usr/bin/perl from 'search' accesses on the directory /var/lib/munin.

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

If sie denken, dass perl standardmässig erlaubt sein sollte, search Zugriff auf munin directory zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# grep munin-cgi-html /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-12-17 11:21:30 UTC
Try to label munin-cgi-html CGI script using

# chcon -t httpd_munin_script_exec_t PATHO/munin-cgi-html

Also what does

# rpm -qf PATHO/munin-cgi-html
