TCPreen - TCP network re-engineering tool - LinuxLinks
TCPreen listens on a TCP port and wait for incoming connections to come in. Then, it forwards data sent by the connecting client to another server port (possibly on another computer) and forwards server responses back to the client.
TCPreen can display data on your console in real-time and/or save it to log files for later reference. Various display formats are available. While it was originally meant to help developers reverse-engineer TCP-based protocols, it can also be very useful to debug network server or client software or for a system administrator to monitor a TCP service.

Sane Break aims to strike a balance between respecting your workflow and ensuring you take the breaks you need.
