First I thought you spelled it wrong, but you continuously have used the
  wrong syntax. Check the command "man iptables" for

-I INPUT (uppercase I) insert rule to the top of chain INPUT
-i eth0 (lowercase i) name of interface packets are received
-A INPUT (uppercase A) append rule to the end of chain INPUT
-a (lowercase a) not a valid option to iptables
