in reply to Simple Construction of a RAW TCP/IP Packet.

Just to share, the code above working properly after updating TCP checksum generation parameter to:

my ($tcp_pseudo) = pack('a4a4CCnnnNNH2B8nvn', $src_host,$dst_host,0,$tcp_proto,$tcp_len, $src_port,$dst_port,$syn,$ack, $tcp_head_reserved,$tcp_all,$tcp_win,$null,$tcp_urg_ptr);

    Hello, I am trying to use this code to send TCP/IP packet but looks like it is not compiling correctly...the protocol field in IP header is 255 (same as one mentioned in socket(RAW,.....). Has anyone run into this issue?
