The server was intended to be simple and with low performance demands, as one of our use-case is to have a Raspberry Pi or a similar embedded system near the antenna and access it over the network. text/html 2018-05-19T17:58:43+00:00 Anonymous (anonymous@undisclosed.example.com) http://jenda.hrach.eu/w/kukuruku/guide?rev=1526752723&do=diff User guide git clone <https://jenda.hrach.eu/p/kukuruku> We test the client on Debian 9 and the server on Debian 8, Debian 9 and Ubuntu 14.04. Howeverer, it should run on any distribution and probably on other UNIX systems too.

Each message in the stream is encapsulated with a 8-byte header, of which 4 bytes are message length and 4 bytes message type (int32_t). Available message types are defined in server/client_parser.h. Protobuf payload is defined in server/c2s.proto.
