Iptables configuration

[Padiyath Sreekumaran]

   Hello,
   I saw that a number of ssh login attepts has been done on my linux
   machine without success. I want to configure the firewall on the machine.
   I have taken over this machine from another person. OS version is
2.6.4-52-smp.
   How I have to configure the machine so that users have access only from
129.129.*.*
   and only ssh access. One should be able to use NFS inside this network. I
know that
   I can use host.deny and host.allow files for user access. But I want to
use
   iptables sw for this. Any help is appreciated. I would like to have an
example 
   if possible.This machine is a production machine. I cannot do any tests
on the 
   machine.

   With regards,
    Kumar
