Description Alexei Panov 2013-03-30 12:16:10 UTC
Description of problem:
SELinux is preventing /usr/bin/python2.7 from 'getattr' accesses on the file /proc/sys/net/ipv4/ip_forward.

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

If вы считаете, что python2.7 следует разрешить доступ getattr к ip_forward file по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
чтобы разрешить доступ, выполните:
# grep firewalld /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
