Hi is there a way to display TCP handshake in Linux? Like for example this WIKI - TCP handshakeNot exactly like the illustration but at least it would show client has sent SYN, ACK, FIN etcand the servers response as well. Just take note I can't use wireshark, tcpdump or other packet capturing programs, just using internal Linux commands, processes or libraries.ThanksUpdateI know this question is closed but I just want to update this coz I found out what I was looking for.Using this command:/proc/net/ip_conntrackits found here: TCP ConnectionsI need to improve my googling skills :)
