NetChat is a combination of NetCat and ppp's "chat", put on steroids for high performance. It is meant as a network exercise tool. Using simple "say this, expect this reply" scripts, NetChat can be made to easilly speak most text-based protocols (such as SMTP, HTTP, POP3 etc.), and many binary protocols, very easilly.
In addition to the above, NetChat is built to perform a large number of concurrent connections. This makes NetChat an ideal network protocol stress-test tool.
Current code is limited to client only and simple send/receive matching. Future extensions will include the ability to work in listen mode, as well as use random elements in the replies and requests.
