Cannot start teamviewer in Fedora 24

Default installation of Teamviewer on Fedora 24 will not start due to SELinux issues.

# systemctl -a | grep teamviewer
  teamviewerd.service  loaded   inactive dead  TeamViewer remote control daemon

# systemctl start teamviewerd.service
Job for teamviewerd.service failed because a fatal signal was delivered to the control process. See "systemctl status teamviewerd.service" and "journalctl -xe" for details.

To fix it you can use SELinux GUI tool:
sealert -b

Or CLI tool:
ausearch -c 'teamviewerd'

Or you can check system logs:
# journalctl -xe

                                      *****  Plugin catchall (100. confidence) suggests   **************************
                                     
                                      If you believe that teamviewerd should be allowed execmem access on processes labeled init_t by default.
                                      Then you should report this as a bug.
                                      You can generate a local policy module to allow this access.
                                      Do
                                      allow this access for now by executing:
                                      # ausearch -c 'teamviewerd' --raw | audit2allow -M my-teamviewerd
                                      # semodule -X 300 -i my-teamviewerd.pp

The solution(shown as a hint in sealert and journalctl), which is to run:
# ausearch -c 'teamviewerd' --raw | audit2allow -M my-teamviewerd
# semodule -X 300 -i my-teamviewerd.pp

 After that you should be able to start Teamviewer service:
 systemctl start teamviewerd.service
[root ~] # systemctl status teamviewerd.service

Custom openvpn port with SElinux enabled

Today I had to setup openvpn client connecting to the server on non-standard port.
Having SElinux enabled always make such things more "interesting".
Openvpn service has started up but in the logs I have found following alerts:

May 22 11:26:30 rhs333 setroubleshoot: SELinux is preventing the openvpn (openvpn_t) from connecting to port 5517. For complete SELinux messages. run sealert -l afe57636-f6d8-4df9-b9c3-1f2d25784025

You can find currently allowed ports by running:

# semanage port -l | grep openvpn_port_t
openvpn_port_t                 tcp       1194, 9997
openvpn_port_t                 udp      1194

Adding non-standard port is easy:

# semanage port -a -t openvpn_port_t -p tcp  5517

Finally restart openvpn service and it should work fine.
