mlsmaycon 5720c33be9 [management] Fix what a second review found in the credential check
Four defects and two pieces of wording, from cubic's pass over the branch.

A provider that asks the proxy to skip TLS verification was checked with a
client that verifies it, so a self-hosted endpoint behind a self-signed
certificate was refused for the one reason its operator had already declared
they accept. Those records now save unchecked, alongside the other cases this
cannot speak for. Sending the credential over a connection management declines
to verify was the other way out, and a worse one.

A key pasted with surrounding whitespace passed its check and then failed every
request: the vendor call trims before building the auth header, the synthesiser
substitutes the stored value verbatim. The key is now stored in the form it
will be sent, so what was checked is what runs.

The proxy-guard test resolved api.openai.com for real before reaching its own
transport, and on a runner with no egress that lookup failed as an
UnreachableError too — so it passed while never exercising the socket guard it
is named for.

A DNS timeout said only that the lookup failed. It now says so as a timeout,
without borrowing the wording of a connection that was never attempted.

The create description promised more than the check delivers: for Bedrock the
runtime host is resolved but never contacted, so a public host that does not
answer is still stored. It says that now, and names the TLS exemption above.
The invalid-upstream message no longer quotes the URL back, which was the one
path in this feature that echoed what the operator typed.

The live suite's single-vendor scope and its dependence on vendor availability
are now stated where the tests are, rather than left to be rediscovered.

🤖 NetBird Agent Network (Beta)

Identity-aware access control for AI agents — keyless access to LLM APIs and private resources over the encrypted NetBird tunnel. See agent-network/ or read the docs at netbird.ai.

NetBird combines a configuration-free peer-to-peer private network and a centralized access control system in a single platform, making it easy to create secure private networks for your organization or home.

Connect. NetBird creates a WireGuard-based overlay network that automatically connects your machines over an encrypted tunnel, leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.

Secure. NetBird enables secure remote access by applying granular access policies while allowing you to manage them intuitively from a single place. Works universally on any infrastructure.

Quickstart with NetBird Cloud

Quickstart with self-hosted NetBird

This is the quickest way to try self-hosted NetBird. It should take around 5 minutes to get started if you already have a public domain and a VM. Follow the Advanced guide with a custom identity provider for installations with different IdPs.

Infrastructure requirements:

  • A Linux VM with at least 1 CPU and 2 GB of memory.
  • The VM should be publicly accessible on TCP ports 80 and 443 and UDP port 3478.
  • A public domain name pointing to the VM.

Software requirements:

Steps

  • Download and run the installation script:
export NETBIRD_DOMAIN=netbird.example.com; curl -fsSL https://github.com/netbirdio/netbird/releases/latest/download/getting-started.sh | bash

A bit on NetBird internals

  • Every machine in the network runs the NetBird agent, which manages WireGuard.
  • Every agent connects to the Management Service, which holds network state, manages peer IPs, and distributes updates to agents.
  • Agents use ICE (via pion/ice) to discover connection candidates for peer-to-peer connections.
  • Candidates are discovered with the help of STUN servers.
  • Agents negotiate a connection through the Signal Service, exchanging end-to-end encrypted messages with candidates.
  • When NAT traversal fails (e.g. mobile carrier-grade NAT) and a direct p2p connection isn't possible, the system falls back to a Relay Service and a secure WireGuard tunnel is established through it.

Support acknowledgement

In November 2022, NetBird joined the StartUpSecure program sponsored by the Federal Ministry of Education and Research of the Federal Republic of Germany. Together with the CISPA Helmholtz Center for Information Security, NetBird brings security best practices and simplicity to private networking.
