You should learn a bit about TCP protocol.
S is for SYN (synchronize)
P is for PUSH
F is for FIN
. is for nothing
Pakets are:
3 way hand shake initiate TCP connection
client > server SYN
sever > client SYN ACK
client > server ACK
client > server send data
server > client ACK and send data
client > server ACK
tTermination
client > server FIN
server > client ACK
server > cient FIN
client > server ACK
ACk means acknowledge.
