hi,

  in the case of segment arrives ( rfc 793 pg. no 64 ),  when tcp is in the closed state, if a reset packet has to be sent out,
  the rfc specifies the cases when the ack flag is set in the incoming packet. 
  
  what happens if a syn flag is set or a fin is set along with ack in the incoming packet... what should be the sequence number in that case of the outgoing reset packet ?? 

  to elaborate my doubt,

  suppose for an incoming packet of tcp length 60 and ack num is 500, let us suppose, and the flags set are ack, and syn. what should be the sequence number of the reset packet that has to be sent out.  since the syn occupies one sequence number, should the seq. no be 60 + 500 + 1 or just 60 + 500.

thanx in advance,
uday.
