i want to implement smtp protocol on the same machine.i have a libpcap trace file..in which i have captured mail traffic..(single session).and i want to develop a program which can read this trace file..and communicate with the smtp server... first packet is Sync packet in trace file..so i want to send it to smtp server...and then i want my progrem to handle the reply sent by server..(say it sent Syn-Ack) anf then my prgm should reply accordingly.. for doing this i am using PF_PACKET , SOCK_RAW and using sendto function...i am sending the packet..im able to see it through tcpdump...but theserver is not replying...why??i am wrking with linux Redhat 9 kernel 2.4.20-8
(...if u r familiar with flowreplay tool..i want to do something similar ...but mine is single session..so less complicated...)
