Description Anass Ahmed 2018-05-02 18:30:22 UTC
Description of problem:
Trying to connect to SSH Tunnel using GNOME Network Manager SSH plugin.
SELinux is preventing ssh from read, write access on the chr_file tun.

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

If you believe that ssh should be allowed read write access on the tun chr_file 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 'ssh' --raw | audit2allow -M my-ssh
# semodule -X 300 -i my-ssh.pp
