This PR aims to integrate Rosenpass with NetBird. It adds a manager for Rosenpass that starts a Rosenpass server and handles the managed peers. It uses the cunicu/go-rosenpass implementation. Rosenpass will then negotiate a pre-shared key every 2 minutes and apply it to the wireguard connection. The Feature can be enabled by setting a flag during the netbird up --enable-rosenpass command. If two peers are both support and have the Rosenpass feature enabled they will create a post-quantum secure connection. If one of the peers or both don't have this feature enabled or are running an older version that does not have this feature yet, the NetBird client will fall back to a plain Wireguard connection without pre-shared keys for those connections (keeping Rosenpass negotiation for the rest). Additionally, this PR includes an update of all Github Actions workflows to use go version 1.21.0 as this is a requirement for the integration. --------- Co-authored-by: braginini <bangvalo@gmail.com> Co-authored-by: Maycon Santos <mlsmaycon@gmail.com> |

netbird Signal Server
This is a netbird signal-exchange server and client library to exchange connection information between netbird peers
Command Options
The CLI accepts the command management with the following options:
start Netbird Signal Server daemon
Usage:
netbird-signal run [flags]
Flags:
-h, --help help for run
--letsencrypt-domain string a domain to issue Let's Encrypt certificate for. Enables TLS using Let's Encrypt. Will fetch and renew certificate, and run the server with TLS
--port int Server port to listen on (e.g. 10000) (default 10000)
--ssl-dir string server ssl directory location. *Required only for Let's Encrypt certificates. (default "/var/lib/netbird/")
Global Flags:
--log-file string sets Netbird log path. If console is specified the the log will be output to stdout (default "/var/log/netbird/signal.log")
--log-level string (default "info")
Running the Signal service (Docker)
We have packed the Signal server into docker image. You can pull the image from Docker Hub and execute it with the following commands:
docker pull netbirdio/signal:latest
docker run -d --name netbird-signal -p 10000:10000 netbirdio/signal:latest
The default log-level is set to INFO, if you need you can change it using by updating the docker cmd as followed:
docker run -d --name netbird-signal -p 10000:10000 netbirdio/signal:latest --log-level DEBUG
Run with TLS (Let's Encrypt).
By specifying the --letsencrypt-domain the daemon will handle SSL certificate request and configuration.
In the following example 10000 is the signal service default port, and 443 will be used as port for Let's Encrypt challenge and HTTP API.
The server where you are running a container has to have a public IP (for Let's Encrypt certificate challenge).
Replace with your server's public domain (e.g. mydomain.com or subdomain sub.mydomain.com).
# create a volume
docker volume create wiretrustee-signal
# run the docker container
docker run -d --name netbird-signal \
-p 10000:10000 \
-p 443:443 \
-v netbird-signal:/var/lib/netbird \
netbirdio/signal:latest \
--letsencrypt-domain <YOUR-DOMAIN>
For development purposes:
The project uses gRpc library and defines service in protobuf file located in:
proto/signalexchange.proto
To build the project you have to do the following things.
Install golang gRpc tools:
#!/bin/bash
go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.26
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.1
Generate gRpc code:
#!/bin/bash
protoc -I proto/ proto/signalexchange.proto --go_out=. --go-grpc_out=.
