    hello, 
    
    I am trying to figure out a problem i have seen with a 
    tcp/ip stack of an equipement, but i need some help in 
    order to finish my C code :) I read this mailing-list 
    for quite a long time and i am sure there are some 
    gurus here :)) 
    
    I successfully emulate a tcp client for the three 
    handshake with raw-ip socket (with all the tcp options, 
    seq num etc.. i wanted ), but when i received the 
    second packet the system send also a RST back to the 
    host i am trying to connect to, which is for my system  
    point of view an unsollicited SYN/ACK packet. 
    
    so i have 
    -> SYN 
    <- SYN/ACK 
    -> RST ( system part )  :( 
    -> ACK ( my prog ) 
    ...
    
    Does anybody have a mean to prevent the system to send 
    this RST ? 
    
    Any help will be appreciated :) 
    
    Quentin.
