# lws minimal ws server raw vhost
|
||
|
|
|
||
|
|
This demonstrates setting up a vhost to listen and accept raw sockets.
|
||
|
|
Raw sockets are just sockets... lws does not send anything on them or
|
||
|
|
interpret by itself what it receives on them. So you can implement
|
||
|
|
arbitrary tcp protocols using them.
|
||
|
|
|
||
|
|
This isn't very useful standalone as shown here for clarity, but you can
|
||
|
|
freely combine a raw socket vhost with other lws server
|
||
|
|
and client features and other vhosts handling http or ws.
|
||
|
|
|
||
|
|
Becuase raw socket events have their own callback reasons, the handlers can
|
||
|
|
be integrated in a single protocol that also handles http and ws
|
||
|
|
server and client callbacks without conflict.
|
||
|

|

|
## build
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cmake . && make
|
||
|
|
```
|
||
|
|
|
||
|
|
## usage
|
||
|
|
|
||
|
|
-s means listen using tls
|
||
|
|
|
||
|
|
```

Connect one or more sessions to the server using netcat... lines you type
|
||
|
|
into netcat are sent to the server, which echos them to all connected clients.
