Functions

func TestICMP

func TestICMP(sourceNS netns.NsHandle, protocol nftables.TableFamily, saddr, daddr *nftableslib.IPAddr) error

TestICMP tests icmp connectivity between two namespaces, ping is initiated in source namespace and destination namespace is expected to reply with echo reply packets

Types

type P2PTestEnv

type P2PTestEnv interface {
	Cleanup()
	GetNamespace() []netns.NsHandle
	GetIPs() []*nftableslib.IPAddr
}

P2PTestEnv defines methods to interact with an instantiated p2p test environment

func NewP2PTestEnv

func NewP2PTestEnv(version nftables.TableFamily, ip1s, ip2s string) (P2PTestEnv, error)

NewP2PTestEnv sets up two new net namespaces, builds a link between them and assigns ip addresses to each end of the link. It also checks connectivity by using ping.
