# 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.
