Hello Ged and all other
Thank you very much.
Here is my first question:
The iptables configuration is as follows:
$ sudo iptables -L
Output:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
I have read that with this configuration, my browser only accepts data
from the Internet, if it has requested the data. This means that all
packets that the browser has not requested are dropped.
Question 1:
Which programme now ensures that data acceptance of unrequested packets
is dropped with the above iptables configuration? Is it Netfilter? In
this case, does Netfilter filter out these unrequested packets?
Question 2:
If Netfilter is filtering out these packets: I assume that if we would
switch off or uninstall Netfilter, then the browser would also accept
packets from the Internet that the browser has not requested. Right?
Very interested in this. Thank you.
