* fix(hbbs): bound the punch-request record store PUNCH_REQS grew without limit; its dedupe scan only covers the newest 30 entries, so cycling 31 online peer ids from one source appended a record per request for the lifetime of the process. Keep at most 10,000 entries, evicting the oldest.

Reject longer ids in RegisterPk and RegisterPeer, the same bound the Pro server uses.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PkpVy2ufxgEjKd3SjXPnJ8 * test(hbbs): assert which punch-request records survive eviction The length check alone passed if the newest record were evicted or new records were dropped once full. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PkpVy2ufxgEjKd3SjXPnJ8 * test(hbbs): cover MAX_PUNCH_REQUESTS=0 in the punch-request test At zero capacity the loop never ran and the new front/back asserts unwrapped an empty queue. Make at least one request so the disabled path is exercised, and only check eviction order when records are kept.

RustDesk Server Program
Configuration & environment variables
Self-host your own RustDesk server, it is free and open source.
Important
Need more features? RustDesk Server Pro might suit you better.
Want to develop your own server? Start with rustdesk-server-demo, a simpler starting point than this repository.
How to build manually
cargo build --release
Three executables will be generated in target/release.
- hbbs - RustDesk ID/Rendezvous server
- hbbr - RustDesk relay server
- rustdesk-utils - RustDesk CLI utilities
You can find updated binaries on the Releases page.
Configuration
hbbs and hbbr can be configured with command-line flags, environment
variables, or an .env / config file. Run hbbs --help or hbbr --help to see
the available flags.
The most common options:
| Option | Flag | Env var | Applies to | Purpose |
|---|---|---|---|---|
| Key | -k |
KEY |
hbbs, hbbr | hbbs loads/generates one by default |
| Bind address | -b |
BIND |
hbbs, hbbr | Local IP address to listen on (default: all interfaces; requires 1.1.17+) |
| Port | -p |
PORT |
hbbs, hbbr | Listening port (hbbs 21116, hbbr 21117) |
| Relay servers | -r |
RELAY-SERVERS |
hbbs | Override when the relay uses a different address or a non-standard port |
| Force relay | — | ALWAYS_USE_RELAY |
hbbs | Y disables direct connections |
| Log level | — | RUST_LOG |
hbbs, hbbr | e.g. debug (default info) |
See docs/environment-variables.md for the full list of variables, the file/flag/env precedence rules, database and relay bandwidth tuning, Docker image variables, and examples.
