# 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 ``` ```txt INFO: packer: 2017/03/02 19:16:52.652109 run.go:47: startup -=-=-=-=-=-=-=-=-=-= INFO: genericlistener: 2017/03/02 19:16:52.652777 manager.go:77: ConnectionTable starting INFO: genericlistener: 2017/03/02 19:16:52.652806 connection_table.go:67: ConnectionTable starting INFO: genericlistener: 2017/03/02 19:16:52.652826 manager.go:84: &{map[] 0xc420072420 0xc420072480} INFO: genericlistener: 2017/03/02 19:16:52.652832 connection_table.go:50: Reaper waiting for 300 seconds INFO: genericlistener: 2017/03/02 19:16:52.652856 manager.go:100: register fired 8443 INFO: genericlistener: 2017/03/02 19:16:52.652862 manager.go:110: listener starting up 8443 INFO: genericlistener: 2017/03/02 19:16:52.652868 manager.go:111: &{map[] 0xc420072420 0xc420072480} INFO: genericlistener: 2017/03/02 19:16:52.652869 conn_tracking.go:25: Tracking Running ``` ### 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 ```javascript { "type": "servers/GET", "schema": "", "txts": 1490473843, "txid": 8, "error": "ok", "error_description": "", "error_uri": "", "result": { "servers": [{ "server_name": "0xc42014a0c0", "server_id": 1, "domains": [{ "domain_name": "hfc.rootprojects.org", "server_id": 1, "bytes_in": 4055, "bytes_out": 8119, "requests": 12, "responses": 12, "source_addr": "127.0.0.1:55875" }, { "domain_name": "test1.hfc.rootprojects.org", "server_id": 1, "bytes_in": 0, "bytes_out": 0, "requests": 0, "responses": 0, "source_addr": "127.0.0.1:55875" }], "duration": 182.561747754, "idle": 21.445976033, "bytes_in": 8119, "bytes_out": 4055, "requests": 12, "responses": 12, "source_address": "127.0.0.1:55875" }, { "server_name": "0xc4200ea3c0", "server_id": 2, "domains": [{ "domain_name": "hfc.rootprojects.org", "server_id": 2, "bytes_in": 1098, "bytes_out": 62, "requests": 2, "responses": 2, "source_addr": "127.0.0.1:56318" }, { "domain_name": "test1.hfc.rootprojects.org", "server_id": 2, "bytes_in": 0, "bytes_out": 0, "requests": 0, "responses": 0, "source_addr": "127.0.0.1:56318" }], "duration": 65.481814913, "idle": 23.589609269, "bytes_in": 62, "bytes_out": 1098, "requests": 2, "responses": 2, "source_address": "127.0.0.1:56318" }] } } ```
