WebThis did trigger hostA to send a tcp ecn enabled packet to hostB, but since scapy works in user space and not particularly with Linux Kernel TCP I could not extract the the congestion window parameters . I then used StraemSocket() module of scapy to tie scapy connection to linux TCP socket. Hosta = server(a.a.a.a), HostB =client(b.b.b.b) WebHello! I am looking for some helping writing a python code for a TCP 3 way handshake between me and a server. I have specific source (a spoofed one) and destination IPs and also ports. The goal is to use scapy instead of sockets. We could discuss further details over discord. Any help is appreciated!
