All ports blocked, but iptables not installed
I have done an absolute minimal install of redhat 9. Iptables and ipchains are not installed. And yet there are no open ports on this machine. I can ping other machines on the network from this machine, but I can not ping this machine from the other machines on the network. Running netstat -vat returns an empty list.
What is it that is blocking ports, or what package might be missing that would enable the ports?
