# lws minimal secure streams
|
||||
|
||||
The application goes to https://warmcat.com and reads index.html there.
|
||||
|
||||
It does it using Secure Streams... the main code in minimal-secure-streams.c
|
||||
just sets up the context and opens a secure stream of type "mintest".
|
||||
|
||||
The handler for state changes and payloads for "mintest" is in ss-myss.c
|
||||
|
||||
The information about how a "mintest" stream should connect and the
|
||||
protocol it uses is kept separated in policy-database.c
|
||||
|
||||
## build
|
||||
|
||||
```
|
||||
$ cmake . && make
|
||||
```
|
||||
|
||||
## usage
|
||||
|
||||
Commandline option|Meaning
|
||||
---|---
|
||||
-d <loglevel>|Debug verbosity in decimal, eg, -d15
|
||||
-f| Force connecting to the wrong endpoint to check backoff retry flow
|
||||
-p| Run as proxy server for clients to connect to over unix domain socket
|
||||
--force-portal|Force the SS Captive Portal Detection to feel it's behind a portal
|
||||
--force-no-internet|Force the SS Captive Portal Detection to feel it can't reach the internet
