Variables

var Error = errs.Class("contact")

Error is the default error class for contact package.

Types

type Config

type Config struct {
	ExternalAddress string `user:"true" help:"the public address of the node, useful for nodes behind NAT" default:""`
}

Config contains configurable values for contact service

type Endpoint

type Endpoint struct {
	// contains filtered or unexported fields
}

Endpoint implements the contact service Endpoints.

func NewEndpoint

func NewEndpoint(log *zap.Logger, service *Service) *Endpoint

NewEndpoint returns a new contact service endpoint.

func (*Endpoint) CheckIn

func (endpoint *Endpoint) CheckIn(ctx context.Context, req *pb.CheckInRequest) (_ *pb.CheckInResponse, err error)

CheckIn is periodically called by storage nodes to keep the satellite informed of its existence, address, and operator information. In return, this satellite keeps the node informed of its reachability. When a node checks-in with the satellite, the satellite pings the node back to confirm they can successfully connect.

func (*Endpoint) GetTime

func (endpoint *Endpoint) GetTime(ctx context.Context, req *pb.GetTimeRequest) (_ *pb.GetTimeResponse, err error)

GetTime returns current timestamp

type Service

type Service struct {
	// contains filtered or unexported fields
}

Service is the contact service between storage nodes and satellites. It is responsible for updating general node information like address, capacity, and uptime. It is also responsible for updating peer identity information for verifying signatures from that node.

architecture: Service

func NewService

func NewService(log *zap.Logger, self *overlay.NodeDossier, overlay *overlay.Service, peerIDs overlay.PeerIdentities, dialer rpc.Dialer) *Service

NewService creates a new contact service.

func (*Service) Close

func (service *Service) Close() error

Close closes resources

func (*Service) Local

func (service *Service) Local() overlay.NodeDossier

Local returns the satellite node dossier

func (*Service) PingBack

func (service *Service) PingBack(ctx context.Context, address string, peerID storj.NodeID) (_ bool, _ string, err error)

PingBack pings the node to test connectivity.
