TCP port 25 traffic Traces

TCP port 25 traffic Traces This is traffic related to TCP port 25 generated by clients inside the network of University of Napoli, Federico II - UNINA - reaching the outside world (i.e. src host from UNINA and dst port tcp 25 OR dst host from UNINA and src port tcp 25). The link observed is a link at 200Mbps connecting the University of Napoli "Federico II" network to the rest of the Internet. These traces are in tcpdump format. Packet lenghts are variable because, for each packet, we stored full TCP headers including optional headers (e.g. MSS). Because of privacy concerns, IP addresses have been replaced preserving network membership. These traces constitute a subset of many traces we started collecting since year 2004.
