CurveCP — Message-handling programs


curvecpmessage [-q (optional)] [-Q (optional)] [-v (optional)] [-c (optional)] [-C
(optional)] [-s (optional)] [prog]


This manual page documents briefly the CurveCP commands.

A traditional UNIX-style server such as ftpd handles just one network connection, reading
input from stdin and writing output to stdout. A "superserver" such as inetd or tcpserver
listens for network connections and starts a separate server process for each connection.

The CurveCP command-line tools have an extra level of modularity. The curvecpserver
superserver listens for network connections. For each connection, curvecpserver starts the
curvecpmessage message handler; curvecpmessage then starts a server such as ftpd. Then
ftpd sends a stream of data to curvecpmessage, which in turn sends messages to
curvecpserver, which encrypts and authenticates the messages and sends them inside network
packets. At the same time curvecpclient receives network packets, verifies and decrypts
messages inside the packets, and passes the messages to curvecpmessage; curvecpmessage
sends a stream of data to ftpd. The same curvecpmessage tool is also used by

curvecpserver and curvecpclient can use programs other than curvecpmessage. Those programs
can directly generate messages in the CurveCP message format without talking to separate
tools such as ftpd; or they can support a completely different protocol that reuses
CurveCP's cryptographic layer but transmits different kinds of messages.


How to use curvecpmessage:

-q optional

-v optional
print extra information

-c optional
program is a client; server starts first

-C optional
