simple tcp re-engineering tool
TCPreen is a simple tool to monitor and analyze data transmitted between a client and a server via a TCP connection, it supports both IPV4 and IPV6. This tool focuses on the data stream (software/socket layer), not on the lower level transmission protocol as packet sniffers do.
