- this set of code works great if I am running the node-tunnel-client on a different machine with apache as a web server.
|
### Check Results
|
||||||
- need to work through why serve-https thinks the traffic is inecure.
|
- you should see traffic going to both node-clients hitting the single webserver on the back end.

"domain_name": "test1.hfc.daplie.me",
|

- if a connection is encrypted or not encrypted

To accomplish the above RVPN uses raw TCP sockets, buffered readers, and a custom Listener. This allows protocol detection (multiple services on one port)
|
}],
|
||||||
If we expose 443 and 80 to maximize the ability for tunnel clients and south bound traffic, the RVPN is able to deal with this traffic on a limited number of ports, and the most popular ports.

A Poor Man's Reverse VPN written in Go
|
|
||||||
|
|
||||||
Context
|
|
||||||
-------
|
|
||||||
|
|
||||||
Even in the worst of conditions the fanciest of firewalls can't stop a WebSocket
|
|
||||||
running over https from creating a secure tunnel.
|
|
||||||
|
|
||||||
Whether at home behind a router that lacks UPnP compliance, at school, work,
|
|
||||||
the library - or even on an airplane, we want any device (or even a browser or
|
|
||||||
app) to be able to serve from anywhere.
|
|
||||||
|
|
||||||
Motivation
|
|
||||||
----------
|
|
||||||
|
|
||||||
We originally wrote this in node.js as
|
|
||||||
[node-tunnel-server](https://git.daplie.com/Daplie/node-tunnel-server),
|
|
||||||
but there are a few problems:
|
|
||||||
|
|
||||||
* metering
|
|
||||||
* resource utilization
|
|
||||||
* binary transfer
|
|
||||||
|
|
||||||
### metering
|
|
||||||
|
|
||||||
We want to be able to meter all traffic on a socket.
|
|
||||||
In node.js it wasn't feasible to be able to track the original socket handle
|
|
||||||
all the way back from the web socket authentication through the various
|
|
||||||
wrappers.
|
|
||||||
|
|
||||||
A user connects via a websocket to the tunnel server
|
|
||||||
and an authentication token is presented.
|
|
||||||
If the connection is established the socket should then be metered and reported
|
|
||||||
including total bytes sent and received and size of payload bytes sent and
|
|
||||||
received (because the tunnelling adds some overhead).
|
|
||||||
|
|
||||||
### resource utilization
|
|
||||||
|
|
||||||
node.js does not support usage of multiple cores in-process.
|
|
||||||
The overhead of passing socket connections between processes seemed non-trivial
|
|
||||||
at best and likely much less efficient, and impossible at worst.
|
|
||||||
|
|
||||||
### binary transfer
|
|
||||||
|
|
||||||
node.js doesn't handle binary data very well. People will be transferring
|
|
||||||
gigabytes of data.
|
|
||||||
|
|
||||||
Short Term Goal
|
|
||||||
----
|
|
||||||
|
|
||||||
Build a server compatible with the node.js client (JWT authentication)
|
|
||||||
that can meter authenticated connections, utilize multiple cores efficiently,
|
|
||||||
and efficienty garbage collect gigabytes upon gigabytes of transfer.
