splitproxy

Reverse TCP proxy server for Linux, used for piping requests and responses to a secondary server without copying data into user space.

usage

splitproxy <port> <remotehost:port> <logginghost:port>

ex: splitproxy 80 10.0.1.1:80 10.0.1.2:80 listens on port 80, tees the incoming request to 10.0.1.1:80 and 10.0.1.2:80, then tees the response to the client and 10.0.1.2:80.

testing

make test creates

1. testclient <host:port> - a client that pipes stdin to a socket with connected to host:port
2. testserver <port> which listens on and pipes socket data to stdout

./test/test.sh

1. pipes data from ./test/in.txt to tcpclient
2. tcpclient connects to splitproxy
3. splitproxy connects to two testservers and streams the proxy's incoming data to the testservers
4. diffs the files and prints either the diff, or a success message if the diff is empty.
