Developing (linux)

tap (linux only, root privilidges required) Program opens a TAP interface and assigns an IP address to it and exposes the interface via a HTTP interface. This program is run with root privilidges to facilitate debugging of lneto since no root privilidges are required to interact with the HTTP interface exposed.
- POST http://127.0.0.1:7070/send: Receives a POST with request body containing JSON string of data to send over TAP interface. Response contains only status code.
- GET http://127.0.0.1:7070/recv: Receives a GET request. Response contains a JSON string of oldest unread TAP interface packet. If string is empty then there is no more data to read.
stack Contains stack implementation which can interact with tap program. No root privilidges required.
- Can expose a HTTP server.
