A node is a VPN server without a panel. awg-agent on it dials the panel
(core) over an outbound WSS connection and runs the panel's requests on its
own awg-ctrl, which stays on 127.0.0.1 and is unchanged. No inbound port on
the node, works behind NAT.
- awg-ui/nodes.ts: node registry in ui.db, WSS hub on NODE_PORT with a
self-signed cert whose SPKI pin goes into the join string, RPC with
timeouts, health polling, /ui/nodes routes.
- Nodes enroll with a one-time awgjoin:// string (secret stored hashed,
1 hour) and then authenticate by their own Ed25519 key. The agent checks
the pin before sending anything and only forwards /health, /api/*, /awg/*.
- server_id 0 is the panel's own awg-ctrl; LOCAL_NODE=off makes the panel
run without a VPN of its own. The panel picks a server with X-Server-Id,
API keys use their server_id. sen:// still serves one server.
- UI: a card per server in the server bar, switching remounts the tab,
«Добавить сервер» gives the join command.
- CLI: agent service, roles from cli.env, join / unjoin commands.
- Release archives include awg-agent.
Upstream AmneziaWG 3.x is still shifting under active development
(unanswered kernel-module issues around header protection and
handshake-without-data regressions), so give operators an explicit
opt-out/opt-in instead of always auto-selecting 3.1, and pin the
installed package so unattended-upgrades can't swap the module under
a live server. Surface the running module/tools version and protocol
generation through /health, the CLI status command, and the panel's
server card so a mismatch is visible instead of silent.
Protocol generation is now derived from awg1.conf rather than stored: an
interface speaks 3.1 when HeaderProtectionKey is set and 2.0 otherwise. The
3.0/3.1-only keys (HeaderProtectionKey, ContentPaddingAddition, the
Rekey/Reject/Keepalive timers, MaxHandshakeAttempts, RandomTrailers,
DisableCookies) are read from the conf and emitted only when non-empty, so 2.0
output stays byte-identical — verified by diffing both the client .conf and the
full vpn:// string against the previous implementation.
Changing generation invalidates every issued vpn:// key, so add
POST /api/users/reissue. It recovers the client private key from inside the
stored blob (the only place it exists), keeping ip/pub_key/psk_key intact, so
nothing changes on the wire and users only need to re-import. users gains
key_gen and vpn_key_prev, and users.db is snapshotted before the pass.
install.sh gates 3.1 on module 3.x and kernel >= 5.5 (header protection needs
the chacha library API, absent before 5.5) and falls back to writing a 2.0 conf
instead of aborting, so older kernels keep working as before.
HeaderProtectionKey is generated with awg genpsk and preserved on KEEP_DATA.
The panel marks keys issued on a different generation and offers to reissue
them; /api/v1 now returns gen alongside name/ip/vpn_key.
Also add MIT license headers across the awg-ui sources.
