Types

type Agent

type Agent struct {
	ID           uuid.UUID // ID is a Universally Unique Identifier per agent
	Platform     string    // Platform is the operating system platform the agent is running on (i.e. windows)
	Architecture string    // Architecture is the operating system architecture the agent is running on (i.e. amd64)
	UserName     string    // UserName is the username that the agent is running as
	UserGUID     string    // UserGUID is a Globally Unique Identifier associated with username
	HostName     string    // HostName is the computer's host name
	Ips          []string  // Ips is a slice of all the IP addresses assigned to the host's interfaces
	Pid          int       // Pid is the Process ID that the agent is running under

	Version       string        // Version is the version number of the Merlin Agent program
	Build         string        // Build is the build number of the Merlin Agent program
	WaitTime      time.Duration // WaitTime is how much time the agent waits in-between checking in
	PaddingMax    int           // PaddingMax is the maximum size allowed for a randomly selected message padding length
	MaxRetry      int           // MaxRetry is the maximum amount of failed check in attempts before the agent quits
	FailedCheckin int           // FailedCheckin is a count of the total number of failed check ins
	Skew          int64         // Skew is size of skew added to each WaitTime to vary check in attempts
	Verbose       bool          // Verbose enables verbose messages to standard out
	Debug         bool          // Debug enables debug messages to standard out
	Proto         string        // Proto contains the transportation protocol the agent is using (i.e. h2 or hq)
	Client        *http.Client  // Client is an http.Client object used to make HTTP connections for agent communications
	UserAgent     string        // UserAgent is the user agent string used with HTTP connections
	// contains filtered or unexported fields
}

Agent is a structure for agent objects. It is not exported to force the use of the New() function

func New

func New(protocol string, verbose bool, debug bool) Agent

New creates a new agent struct with specific values and returns the object

func (*Agent) Run

func (a *Agent) Run(server string)

Run instructs an agent to establish communications with the passed in server using the passed in protocol
