minimalist-pcproxy

Minimalist PCP proxy implementation. No client state and minimal server state.

Goals

• portable C code

• small total LoC count

• few dependencies (libubox)

• minimal state (some per-server things)

• follow the IETF specs ( such as http://tools.ietf.org/html/draft-ietf-pcp-proxy-05 and https://tools.ietf.org/html/rfc6887 ) as closely as possible

• embeddable (just take pcp* and run with it, please)

Non-goals

• server selection draft; we do server selection ENTIRELY based on the client's IP address. we also don't track liveliness of servers.

Usage

cmake .
./minimalist-pcproxy 2000:db8::/32=2000:db8::1 ::ffff:0:0/96=2000:db8::2

The command line arguments are (address prefix) = (PCP server) mappings.
