Description of problem: SELinux is preventing /opt/teamviewer8/tv_bin/teamviewerd from 'name_bind' accesses on the tcp_socket . ***** Plugin bind_ports (92.2 confidence) suggests ************************* If you want to allow /opt/teamviewer8/tv_bin/teamviewerd to bind to network port 21876 Then you need to modify the port type. Do # semanage port -a -t -p tcp 21876 ***** Plugin catchall_boolean (7.83 confidence) suggests ******************* If you want to allow system to run with NIS Then you must tell SELinux about this by enabling the 'nis_enabled' boolean. You can read 'None' man page for more details. Do setsebool -P nis_enabled 1 ***** Plugin catchall (1.41 confidence) suggests *************************** If you believe that teamviewerd should be allowed name_bind access on the tcp_socket by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

The problem is there is no policy for /opt/teamviewer8/tv_bin/teamviewerd and you run with disabled unconfined module. Either you can make init_t as unconfined or we can create an initial policy for teamviewerd. # sepolicy generate --init -n teamviewerd PATH_TO_EXECUTABLE # sh teamviewerd.sh

(In reply to Miroslav Grepl from comment #14) > we can create an initial policy for teamviewerd. Yes can you make an initial policy for teamviewerd? I am not a security expert so it is best you make the policy just to make sure it is not trying to do something it should not.
I am reading more about teamviewerd which is not a part of Fedora. Could you try to execute # chcon -t unconfined_exec_t PATH_TO_EXECUTABLE
