# RVPN Server
|
||||
|
||||
## branch: passing-traffic
|
||||
## branch: load-balancing
|
||||
|
||||
- code now passes traffic using just daplie tools
|
||||
- this will require serve-https and node-tunnel-client to work
|
||||
- the system supports round-robin load balancing
|
||||
|
||||
|
||||
### Build RVPN
|

|
||||
```
|
||||
|
||||
- this set of code works great if I am running the node-tunnel-client on a different machine with apache as a web server.
|
||||
- need to work through why serve-https thinks the traffic is inecure.
|
||||
### Check Results
|
||||
- you should see traffic going to both node-clients hitting the single webserver on the back end.
|
||||
- Browse: https://rvpn.daplie.invalid:8443/api/com.daplie.rvpn/servers
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||

||||

||||

||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
## restructured-http
|
||||
|
||||
- connection handling has been totally rewritten.
|
||||
- on a specific port RVPN can determine the following:
|
||||
- if a connection is encrypted or not encrypted
|
||||
- if a request is a wss_client
|
||||
- if a request is an admin/api request
|
||||
- if a request is a plain (to be forwarded) http request
|
||||
- or if a request is a different protocol (perhaps SSH)
|
||||
|
||||
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.
|
||||
It is possible now to meter any point of the connection (not Interface Level, rather TCP)
|
||||
|
||||
There is now a connection manager that dynamically allows new GenericListeners to start on different ports when needed....
|
||||
|
||||
```go
|
||||
newListener := NewListenerRegistration(initialPort)
|
||||
gl.register <- newListener
|
||||
```
|
||||
|
||||
A new listener is created by sending a NewListenerRegistration on the channel.
|
||||
|
||||
```go
|
||||
|
||||
ln, err := net.ListenTCP("tcp", listenAddr)
|
||||
if err != nil {
|
||||
loginfo.Println("unable to bind", err)
|
||||
listenerRegistration.status = listenerFault
|
||||
listenerRegistration.err = err
|
||||
listenerRegistration.commCh <- listenerRegistration

|
||||
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.
