Linux version of Little Snitch

Hello, There is a program on the Apple side of things called 'Little Snitch'. At the point a program tries to connect to the Internet, Little Snitch stops the program at that point tells you what program is trying to connect to the Internet and where it's trying to connect to. Then it allows me to decide if the connection should be made or not. Is there anything on the Linux side I could use to do this? Thanks, Jerome
