https://libwebsockets.org/pipermail/libwebsockets/2019-April/007937.html thanks to Bruce Perens for noting it. This doesn't change the intention or status of the CC0 files, they were pure CC0 before (ie, public domain) and they are pure CC0 now. It just gets rid of the (C) part at the top of the dedication which may be read to be a bit contradictory since the purpose is to make it public domain. |

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
usage
| Commandline option | Meaning |
|---|---|
| -d | Debug verbosity in decimal, eg, -d15 |
| -r ipv4:address:port | Configure the remote IP and port that will be proxied, by default ipv4:127.0.0.1:22 |
