Packets do not contain instructions, only data. If your TCP/IP
implementation doesn't have vulnerabilities any packet shouldn't be a
problem.
Firewall prevents technically legal packets from reaching software that
shouldn't be accessible from the Internet.
In most cases a hacker finds an opened port (port listened to by some
daemon) and connects to it.
Firewall prevents hacker from doing it.
I have wondered since ages ago, likely on windows, I wanted to know
about something, I forget what, and there was one result in Alta Vista
or something.
Go to website there is a message "GO AWAY".
I go away but then curious go back and my computer crashes.
