This tool lives in `combined/perftest/` and is compiled into a standalone binary.\n\n## Approach\n\nUse the **`client/embed` package** (`client/embed/embed.go`) which provides a clean API for programmatically creating NetBird clients. It handles:\n- Userspace WireGuard via netstack (no root needed, no kernel interfaces)\n- In-memory config generation (unique WG keys per peer)\n- Auth + registration with setup key\n- `Dial()`, `ListenUDP()`, `ListenTCP()` for tunnel traffic\n- `Status()` for peer connectivity checks\n\n## New File\n\n### `combined/perftest/main.go`\n\nSingle-file Go program (~400 lines).

Init phase**\n- Parse flags\n- If `--force-relay`, set `os.Setenv(\"NB_FORCE_RELAY\", \"true\")`\n- Set `os.Setenv(\"NB_USE_NETSTACK_MODE\", \"true\")` (embed does this but we set it early)\n\n**2.

Traffic phase**\n- Each peer starts a UDP echo listener via `client.ListenUDP(\":9000\")`\n- For each peer pair (i, j) where i < j:\n  - Peer i sends UDP packets to peer j's tunnel IP via `client.Dial(ctx, \"udp\", \"<peer_j_ip>:9000\")`\n  - Measure round-trip time (echo response) and throughput\n- Run for `--duration` time\n- Collect stats: packets sent, received, lost, avg/min/max RTT, throughput\n\n**5.

However, the `embed` package re-exports `PeerStatusConnected` and `PeerConnStatus`. Let me use those instead.\n\nLooking at embed.go:\n```go\ntype PeerConnStatus = peer.ConnStatus\n\nconst (\n    PeerStatusConnected = peer.StatusConnected\n)\n```\n\nSo I can use `embed.PeerStatusConnected` and `embed.PeerConnStatus` instead. But the `State` type is from `peer.State`... I need to check if `FullStatus` is also re-exported by embed.\n\n\nActually, I realize that in Go you can receive values of internal types from exported functions even if you can't import the package directly—the caller just can't name the type explicitly. So `Status()` returning `peer.FullStatus` is fine; I can work with the returned value and access its fields like `ConnStatus` without needing to import `peer`. you just can't import the internal package directly. But you CAN use the value. The fields are accessible.\n\nWait, actually that's not entirely correct. Let me think more carefully...\n\nThe `embed` package is at `github.com/netbirdio/netbird/client/embed`. The `perftest` is at `github.com/netbirdio/netbird/combined/perftest`. The `internal` package is at `github.com/netbirdio/netbird/client/internal/peer`.\n\nGo's internal package rule: a package can only be imported by code rooted at the parent of the `internal` directory. So `client/internal/peer` can only be imported by packages rooted at `client/`. The `combined/perftest` package is not rooted at `client/`, so it can't import `client/internal/peer`.\n\nHowever, I can receive values of type `peer.FullStatus` from `embed.Status()` and access the struct fields directly, even though I can't name the type. Since `embed` re-exports the constants like `PeerStatusConnected` and `PeerConnStatus`, I should use those instead of trying to reference the internal `peer` package directly.","signature":"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"}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":309,"cache_read_input_tokens":50612,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":309},"output_tokens":8,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYDU91SnMzzbsHfGGmDrR","type":"assistant","uuid":"4db2d947-efd7-4c25-a312-e01425907a6e","timestamp":"2026-02-17T10:17:29.334Z"}

The simplest approach: set the log level to \"panic\" (effectively silent) regardless of the `--log-level` flag, or better, redirect the client's log output to `io.Discard` via the `LogOutput` option in `embed.Options`.\n\nLooking at the embed.Options struct:\n```go\n// LogOutput is the output destination for logs (defaults to os.Stderr if nil)\nLogOutput io.Writer\n```\n\nSo I can set `LogOutput: io.Discard` on each client to suppress all client logs. This is cleaner than messing with log levels since the user might still want `--log-level` for debugging purposes later.\n\n\nI'm thinking the cleanest solution is to always discard client logs by default with `LogOutput: io.Discard`, and if the user needs client debug output in the future, that's an easy change to make. I should probably remove the `--log-level` flag since it was only controlling the client's verbosity anyway.","signature":"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"}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":78,"cache_read_input_tokens":58843,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":78},"output_tokens":13,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYDUk6HiB7zTFk7JYK9NM","type":"assistant","uuid":"f00d04f4-a973-4b77-9b9c-bf808c18824d","timestamp":"2026-02-17T10:25:21.309Z"}

The problem is in `server.NewServer(ctx, dexConfig)` — when Dex initializes, it reads connectors from storage and tries to open/validate them. For OIDC connectors, this means fetching `.well-known/openid-configuration` from the issuer URL. If that IdP is unreachable, `NewServer` fails and the whole management server can't start.\n\nThe key call chain:\n1. `NewProviderFromYAML` → `initializeStorage` → `ensureStaticConnectors` (writes connectors to storage)\n2. `NewProviderFromYAML` → `server.NewServer(ctx, dexConfig)` (Dex reads connectors from storage and initializes them)\n\n\n3. Dex's `NewServer` opens all connectors, which is internal to the library.\n\nI'm considering two approaches: either pre-check if the IdP is reachable before storing the connector in `ensureStaticConnectors`, skipping unreachable ones with a warning, or defer adding OIDC connectors to storage entirely during initialization.\n\nBut there's a complication — connectors are persisted in SQLite, so even if we skip adding them on startup, they'll still be there from previous runs and cause the same issue on restart. The real solution needs to handle connectors that are already in storage but currently unreachable, either by removing or disabling them before calling `server.NewServer`. I think the clearest path forward is to validate connectors in two places: filter out unreachable ones during the static connector setup, and remove any stored connectors that are unreachable before the server starts. Then I can walk through these options with the user to see which approach fits their needs best.","signature":"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"}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":13269,"cache_read_input_tokens":94489,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":13269},"output_tokens":8,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYDhuV6ReDpvTN4mKJnHe","type":"assistant","uuid":"857d71e4-4321-43c1-9ff9-7da9a8dc21f8","timestamp":"2026-02-17T13:18:06.966Z"}
