hi,
I seen some examples allowing all traffic (in INPUT and OUTPUT) from lo
interface. Why is it so? Is it becos of the local XWindow connection?
pls advise...

X requires this, yes; there are also certain other applications which use
things like rpc calls or ident lookups. A simple way to find out what
traffic goes across the lo interface is to log it for a while:
iptables -A INPUT -i lo -j LOG --log-prefix="In-lo: "
iptables -A INPUT -i lo -j ACCEPT
