How I block internet access for a concrete program?
I need block internet access for a program but i don't know why I can configure the firewall for it can do it
I didn't add the info because I'm not aware of a standard way of doing this. More often than not you need to read the documentation which may or many not list the required ports. Some applications also use dynamic ports when required, in which case it's much harder to pin down one port. :(
Please give more detail on what exactly you want to achieve: deny outgoing connections to a program? Which program? Who will run this program? The firewall is probably not able to do what you need, but "unshare -n <program>" may fit your need, or maybe you need to create a SELinux module for this.</program>
What's the thing, @tonioc? LOL
