Hello Friends, 
 
	 I have recently started working on NETGRAPH  .  Even
I am planning to write program for a netgraph node  in
which I could  connect my node to the Ether node and
read the packets  , capture them and  make changes in
the packet fields . 
 
	I have tried out a few things and I have faced
problems in few things such as : 
1)  How to print the packet information on the konsole
when the packet passes through the node. 
2)  How can I make changes in the Packet header 
3)  What are the different types of errors which we
can induce in  TCP/IP connection  
     to test the reliability of TCP/IP 
 
 These are few of my doubts . I will be very grateful 
if someone could help me out with my difficulty.  I
would  definitely be looking forward for some help.
