# RVPN Server

## branch: load-balancing

-   code now passes traffic using just Root tools
-   this will require serve-https and node-tunnel-client to work
-   the system supports round-robin load balancing

### Build RVPN

```bash
go build -mod vendor ./cmd/telebit/
go build -mod vendor ./cmd/telebitd/
```

### Setup Some Entries

`/etc/hosts`:

```txt
127.0.0.1 tunnel.example.com rvpn.rootprojects.invalid hfc2.rootprojects.org hfc.rootprojects.org
```

### Start Up Webserver

```bash
tmp $ cd /tmp
tmp $ vim index.html --- Place some index content
tmp $ serve-https -p 8080 -d /tmp --servername hfc.rootprojects.org --agree-tos --email henry.f.camacho@gmail.com
```

### Start Tunnel Client

```bash
# For .env
TELEBIT_SECRET=abcdef1234567890
```

```bash
node-tunnel-client $ bin/stunnel.js --locals http://hfc.rootprojects.org:8080,http://test1.hfc.rootprojects.org:8080 --stunneld wss://localhost.rootprojects.org:8443 --secret abcdef1234567890
```

### Execute RVPN

```bash
./telebitd
```

```

### Browse via tunnel

https://hfc.rootprojects.org:8443

### Test Load Balancing

In a new terminal

```bash
node-tunnel-client $ bin/stunnel.js --locals http://hfc.rootprojects.org:8080,http://test1.hfc.rootprojects.org:8080 --stunneld wss://localhost.rootprojects.org:8443 --secret abc123
```

### Check Results

-   you should see traffic going to both node-clients hitting the single webserver on the back end.
-   Browse: https://rvpn.rootprojects.invalid:8443/api/org.rootprojects.rvpn/servers
