# RVPN Server
2017-03-03 03:32:53 +00:00
## branch: load-balancing
2017-03-03 03:32:53 +00:00
2020-04-28 06:26:00 +00:00
- 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
2017-03-03 03:32:53 +00:00
### Build RVPN
```bash
2020-04-28 06:26:00 +00:00
go build -mod vendor ./cmd/telebit/
go build -mod vendor ./cmd/telebitd/
2017-03-03 03:32:53 +00:00
```
2020-04-28 06:26:00 +00:00
2017-03-03 03:32:53 +00:00
### Setup Some Entries
2020-04-28 06:26:00 +00:00
`/etc/hosts`:
```txt
127.0.0.1 tunnel.example.com rvpn.rootprojects.invalid hfc2.rootprojects.org hfc.rootprojects.org
2017-03-03 03:32:53 +00:00
```
### Start Up Webserver
2020-04-28 06:26:00 +00:00
2017-03-03 03:32:53 +00:00
```bash
tmp $ cd /tmp
2020-04-28 06:26:00 +00:00
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
2017-03-03 03:32:53 +00:00
```
### Start Tunnel Client
2020-04-28 06:26:00 +00:00
2017-03-03 03:32:53 +00:00
```bash
2020-04-28 06:26:00 +00:00
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
2017-03-03 03:32:53 +00:00
```
### Execute RVPN
```bash
2020-04-28 06:26:00 +00:00
./telebitd
```

### Browse via tunnel
2017-03-03 03:32:53 +00:00
2020-04-28 06:26:00 +00:00
https://hfc.rootprojects.org:8443
### Test Load Balancing
In a new terminal
```bash
2020-04-28 06:26:00 +00:00
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
```
2017-02-02 03:30:15 +00:00
### Check Results
2020-04-28 06:26:00 +00:00
- 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
