Functions

func IsBuiltinQEMU

func IsBuiltinQEMU(network string) bool

IsBuiltinQEMU returns if network is builtin or the legacy value user.

func ParseAddr

func ParseAddr(addr string) (net.IP, *net.IPNet, error)

ParseAddr will try to parse an ip or a cidr address

Types

type Interface

type Interface struct {
	IfaceName string
	IfaceIPv4 string
	IfaceMTU  int
	IfaceMAC  string
}

Interface contains main network interface parameters.

type Parameters

type Parameters struct {
	IP        string // IP address of network
	Netmask   string // dotted-decimal format ('a.b.c.d')
	Prefix    int    // network prefix length (number of leading ones in network mask)
	CIDR      string // CIDR format ('a.b.c.d/n')
	Gateway   string // taken from network interface address or assumed as first network IP address from given addr
	ClientMin string // second IP address
	ClientMax string // last IP address before broadcast
	Broadcast string // last IP address
	IsPrivate bool   // whether the IP is private or not
	Interface
	// contains filtered or unexported fields
}

Parameters contains main network parameters.

func FreeSubnet

func FreeSubnet(startSubnet string, step, tries int) (*Parameters, error)

FreeSubnet will try to find free private network beginning with startSubnet, incrementing it in steps up to number of tries.
