Please leave all security words beside.
I'm the only one who has access to Ubuntu server and I login to it only when I have something to work with system administration. So I know what I'm doing and I'm aware of it. Now my system works with sudo without asking for password. Is it possible that it runs (system) programs without typing sudo?
And once again - I understand that someone can see this as security mistake, but please, don't write about it.
