This PR enhances the version checker to send a custom User-Agent header when polling for updates, and configures both the management CLI and client UI to use distinct agents.
- NewUpdate now takes an `httpAgent` string to set the User-Agent header.
- `fetchVersion` builds a custom HTTP request (instead of `http.Get`) and sets the User-Agent.
- Management CLI and client UI now pass `"nb/management"` and `"nb/client-ui"` respectively to NewUpdate.
- Tests updated to supply an `httpAgent` constant.
- Logs if there is a new version available for management
* add additional metrics
we are collecting active rosenpass, ssh from the client side
we are also collecting active user peers and active users
* remove duplicated
Adds backward compatibility for clients with versions prior to v0.48.0 that do not support port range firewall rules.
- Skips generation of firewall rules with multi-port ranges for older clients
- Preserves support for single-port ranges by treating them as individual port rules, ensuring compatibility with older clients
* Avoid recalculating next peer expiration
- Check if an account schedule is already running
- Cancel executing schedules only when changes occurs
- Add more context info to logs
* fix tests
This PR addresses potential ID collisions by switching the setup key ID generation from a hash-based approach to using xid-generated IDs.
Replace the hash function with xid.New().String()
Remove obsolete imports and the Hash() function
This PR adds persistence for peer feature flags when updating metadata, including equality checks, gRPC extraction, and corresponding unit tests.
- Introduce a new `Flags` struct with `isEqual` and incorporate it into `PeerSystemMeta`.
- Update `UpdateMetaIfNew` logic to consider flag changes.
- Extend gRPC server’s `extractPeerMeta` to populate `Flags` and add tests for `Flags.isEqual`.
With the lazy connection feature, the peer will connect to target peers on-demand. The trigger can be any IP traffic.
This feature can be enabled with the NB_ENABLE_EXPERIMENTAL_LAZY_CONN environment variable.
When the engine receives a network map, it binds a free UDP port for every remote peer, and the system configures WireGuard endpoints for these ports. When traffic appears on a UDP socket, the system removes this listener and starts the peer connection procedure immediately.
Key changes
Fix slow netbird status -d command
Move from engine.go file to conn_mgr.go the peer connection related code
Refactor the iface interface usage and moved interface file next to the engine code
Add new command line flag and UI option to enable feature
The peer.Conn struct is reusable after it has been closed.
Change connection states
Connection states
Idle: The peer is not attempting to establish a connection. This typically means it's in a lazy state or the remote peer is expired.
Connecting: The peer is actively trying to establish a connection. This occurs when the peer has entered an active state and is continuously attempting to reach the remote peer.
Connected: A successful peer-to-peer connection has been established and communication is active.
Fixes panic occurring when body is nil (this usually happens when connections is refused) due to lack of nil check by centralizing response.Body.Close() behavior.
