Description gaganis 2011-05-02 09:38:28 UTC
SELinux is preventing /usr/sbin/openvpn from 'name_connect' accesses on the tcp_socket port 2501.

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

If you believe that openvpn should be allowed name_connect access on the port 2501 tcp_socket 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:
# grep openvpn /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-05-02 10:40:40 UTC
Why is openvpn connecting to this port?


If you want to allow it you need to add a local policy

# grep openvpn /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 2 gaganis 2011-05-02 10:54:45 UTC
The server that I am trying to connect to is using a custom port number that I have configured through NetworkManager. 
Since I could connect with no denial from selinux before it seemed like a bug. 

Sorry about the inconvenience.

Though now that I better understood why this happened I would like to note that I believe that this seems to me to be to strict. Many providers configure openvpn on different ports that the default and this could break non interactive installations.
