Name etcproxy - a TCP proxy in Erlang for various testing purpose. Description This proxy is useful for various network-related tests. It's capable to listen to a local port and relay all traffic on it to certain remote/local address/port. The advanced functionalities includes: * Split upstream packet into packet-per-byte before relaying and vice versa. * Specify delays in forward/backward traffic relaying (delays are inserted every N bytes). * Force connection closing after forward/backward relaying traffic reached certain threshold (in bytes). Synopsis You should first install Erlang which can be obtained from here: http://www.erlang.org/download.html Then you can run etcproxy by running it directly: $ ./etcproxy <local port> [<remote addr>:]<remote port> If <remote addr> is ignored, etcproxy will default to 127.0.0.1. Advanced options can only be turned on by modifying macros in etcproxy script for now, a more convinent command-line interface will be added soon.
