Summary: selinux alerts about rabbitmq server ("access on the
tcp_socket")
Product: Fedora
Version: 20
Component: rabbitmq-server
Assignee: hubert.plociniczak(a)gmail.com
Reporter: pavel.nedr(a)gmail.com

Description of problem:
I've seen flood in journalctl from SEalert about that error.
It begins from startup of the system (rabbitmq is enabled in systemctl)
There is a lot of error messages. They causes "audispd[643]: queue is full -
dropping event" error :)

$ sudo sealert -l 82db9030-74db-4e60-97ab-6aef447e582d
SELinux is preventing /usr/lib64/erlang/erts-5.10.3/bin/beam.smp from name_bind
access on the tcp_socket .
***** Plugin bind_ports (92.2 confidence) suggests ************************
If you want to allow /usr/lib64/erlang/erts-5.10.3/bin/beam.smp to bind to
network port 10097
Then you need to modify the port type.
Do
# semanage port -a -t PORT_TYPE -p tcp 10097
где PORT_TYPE может принимать значения: amqp_port_t, couchdb_port_t,
jabber_client_port_t, jabber_interserver_port_t.
***** Plugin catchall_boolean (7.83 confidence) suggests ******************
If вы хотите выполнить следующее: разрешить NIS
Then you must tell SELinux about this by enabling the 'nis_enabled' boolean.
Дополнительная документация на 'None' ман странице.
Do
setsebool -P nis_enabled 1
***** Plugin catchall (1.41 confidence) suggests **************************
If вы считаете, что beam.smp следует разрешить доступ name_bind к tcp_socket
по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
чтобы разрешить доступ, выполните:
# grep beam.smp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
