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

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

Setup Some Entries

/etc/hosts:

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

Start Up Webserver

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

# For .env
TELEBIT_SECRET=abcdef1234567890

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

Browse via tunnel

https://hfc.rootprojects.org:8443

Test Load Balancing

In a new terminal

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
