ɹǝddoH

iOS VPN client and Linux server stack for a **multi-hop SSH overlay**: traffic is tunneled as raw IP packets over SSH, routed through a chain of nodes, and NAT’d at the exit. One app, one server daemon (`hopperd`), no legacy relays. Setting up a server Each hop in your chain runs hopperd on a Linux VPS. You need one VPS per hop (a single VPS works for a one-hop chain where entry = exit). Get a VPS For the simplest setup, rent the cheapest Ubuntu VPS you can find (any provider — Hetzner, DigitalOcean, Vultr, etc.). Use a fresh machine with: User: root Auth: root password (SSH password login enabled) Deploy from the app You do not need a Mac or deploy.sh to get started. The app installs and configures the server for you: Open ɹǝddoH → Configure chains → Server library. Tap Deploy. Enter the VPS host/IP, user (root), SSH port (22), and root password. Wait for the deploy log to finish — the server is added to your library automatically (no QR scan needed). Add server to your first chain. Open ɹǝddoH → Configure chains → Add server Go back to main screen. Connect! That's simple.
