Description Sven Kieske 2013-09-12 10:11:41 UTC
Description of problem:
SELinux is preventing /usr/sbin/ifconfig from 'getattr' accesses on the file /proc/<pid>/net/dev.

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

If sie denken, dass es ifconfig standardmässig erlaubt sein sollte, getattr Zugriff auf dev file 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 ifconfig /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
