How to block all outgooing traffic and specific program?

Post by CNoob » 2018/03/17 15:50:35

i am new on Linux and have few questions.
How can i block all outgoing traffic to the internet? Only specific programs like Firefox should be able to go in the internet.

and....
is this possible with the gui firewall-config? Or with any other Tools?

Thank you...

It might be that you have to venture into SELinux:

Thank you but it seem to complicated for me as Linux noob.. Is there no other way to block Traffic by program?

Why is this not working:

Code: Select all

iptables -A OUTPUT -m owner --cmd-owner "firefox-bin" -j ACCEPT
Do i need another Kernel?
