Also, change the used queue and Qos by "ovs-vsctl -- set Port s1-eth1 qos=@newqos .....". But when returning to the monitored flow I found that collision and Tx/Rx drop/error were always zero and did not change. The traffic generates using continuous ping, Iperf3, and python server and clients script.

This includes a client, a server and an eavesdropper (middle-man attacker), which can apply MitM attack to the authentication mechanism. Unix tools like netcat and telnet can help test your program. To limit the workload, we provide a simplification on the original SMTP and SMTP-CRAM protocols. We assume all programs are supposed to be run and tested locally and they are not required to be extensible to support TCP connection via the Internet or to be used in real world. No actual data should be sent and received from the Internet, and everything should be contained in the local loopback. We also assume any syntactically valid message under the protocol can be accepted. E.g., No actual che...
