what is the meaning of "loopback" in there?

These two commands have (-A) appended two ACCEPT rules. The OUTPUT rule
(05) allows any packet to (-o) leave via the "loopback" device and the
INPUT rule (04) allows packets to re-enter (-i) via the "loopback".


04- [bash]# iptables -A INPUT -i lo -j ACCEPT
05- [bash]# iptables -A OUTPUT -o lo -j ACCEPT

thanks!

These are needed as some system calls use this address which is 127.0.0.1
You need not be worried about this.
