# lws minimal ws server raw proxy
|
||
|
|
|
||
|
|
This demonstrates how a vhost can be bound to a specific role and protocol,
|
||
|
|
with the example using a lws plugin that performs raw packet proxying.
|
||
|
|
|
||
|
|
By default the example will proxy 127.0.0.1:22, usually your ssh server
|
||
|
|
listen port, on 127.0.0.1:7681. You should be able to ssh into port 7681
|
||
|
|
the same as you can port 22. But your ssh server is only listening on port 22...
|
||
|
|
|
||
|
|
## build
|
||
|
|
|
||
|
|
To build this standalone, you must tell cmake where the lws source tree
|
||
|
|
./plugins directory can be found, since it relies on including the source
|
||
|
|
of the raw-proxy plugin.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cmake . -DLWS_PLUGINS_DIR=~/libwebsockets/plugins && make
|
||
|
|
```
|
||
|
