# lws minimal secure streams server raw

The application sets up a raw tcp server on localhost:7681

It does it using Secure Streams... information about how the server should
operate is held in JSON policy in main.c

Connecting to the server using `echo "hello" | nc --no-shutdown 127.0.0.1 7681`
will send "hello" which is hexdumped to console by the rx function, then
will receive an incrementing message at 100ms intervals.

Note there are two incomaptible versions of netcat around, this is from Fedora's
nmap-ncat, the --no-shutdown is needed to stop it hanging up itself after it
has sent its stdin.

## build

```
 $ cmake . && make
```

## usage

Commandline option|Meaning
---|---
-d <loglevel>|Debug verbosity in decimal, eg, -d15
