thanx a lot,for this upto the mark reply.
for the ans 2) that u gave.
does the TTL decrement at the sender level,or at the receipent level.i.e,is it
decremented and sent,or sent and then at the other side decremented????
for the ans 3) that u gave,
if my packet is not fragmented,if i fill identification field with random bits
then wud that make a difference???
for the ans 4) ,
do u think raw sockets will help me in anyway for my purpose???n also
at which layer r the sockets formed??
well for 2 i assume the ttl is decremented as it is sent on to the next hop, as if it were addressed for itself it wouldn't decrement.
for 3 and 4 i have no idea... read the tcp/ip standards and ttl is an IP attribute, so would be checked at the layer equivalent to IP. i'm sure you can find which one that is yourself.
