Kernel Debugging

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Dear Sirs,
I tried to modify code for TCP in linux kernel-2.2.14. My purpose was to
make it stateless during connection establishment, so that it's free from
SYN-attacks. 
At present this is what happens when any other machine tries to open a
connection with this host :

	this host	any other host
	        <--------- SYN
	SYN+ACK  ---------> 
                <--------- ACK
	RST      --------->    (despite the fact that ACK is a valid one)

I wish to debug this. How can I go about it ? Is there some way I can go
thru the stages that the packet goes thru, making the kernel display some
message at each stage during tcp_rcv_msg ?

Thanks and regards,
Priyank.
