Hrmmh, it appears I didn't pay much attention to the subject.

It really depends on how deep you want to dig into the topic. For
security purposes, you should definitely learn basics of networking
(ports, IP addresses, routing etc). This knowledge is generally
indepentend of the operating system. You can then go ahead and learn
about iptables which is used in the Linux kernel for packet filtering
and manipulation

For the purpose yo described you don't need to know anything about that.
Only that apparently nobody on this list knows a program that can do
what you know from Windows.

If you don't rely on them as security tools, they may help, yes.

But I still don't completely understand your situation. You said you are
on dialup and want to prevent unnecessary traffic. Can't you just
disable auto-dialling? Which specific programs use the network without
your consent?

I have been manipulated and permanently distorted.
