Functions

func FindIPv6Master

func FindIPv6Master() (master string, err error)

FindIPv6Master finds which interface to use as master for NDMZ npub6 interface

Types

type DHCPMon

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

DHCPMon monitor a network interface status and force renew of DHCP lease if needed

func NewDHCPMon

func NewDHCPMon(iface, namespace string, z *zinit.Client) *DHCPMon

NewDHCPMon create a new DHCPMon object managing interface iface namespace is then network namespace name to use. it can be empty.

func (*DHCPMon) Start

func (d *DHCPMon) Start(ctx context.Context) error

Start creates a zinit service for a DHCP client and start monitoring it this method is blocking, start is in a goroutine if needed. cancel the context to start it.

type DMZ

type DMZ interface {
	// create the ndmz network namespace and all requires network interfaces
	Create(ctx context.Context) error
	// delete the ndmz network namespace and clean up all network interfaces
	Delete() error
	// link a network resource from a user network to ndmz
	AttachNR(networkID string, nr *nr.NetResource, ipamLeaseDir string) error
	// Return the interface used by ndmz to router public ipv6 traffic
	IP6PublicIface() string
	//configure an address on the public IPv6 interface
	SetIP6PublicIface(net.IPNet) error
}

DMZ is an interface used to create an DMZ network namespace
