Functions

func AddNS

func AddNS(tb testing.TB) string

AddNS adds a randomly named network namespace

func SetupCrossNsDNAT

func SetupCrossNsDNAT(tb testing.TB) (ns string)

SetupCrossNsDNAT sets up a network namespace, a veth pair, and a NAT rule in the specified network namespace. Redirecting port 80 to 8080 within the namespace.

func SetupCrossNsDNAT6

func SetupCrossNsDNAT6(t *testing.T) (ns string)

SetupCrossNsDNAT6 sets up a network namespace, along with two IPv6 addresses fd00::1 and fd00::2 to be used for namespace aware tests. fd00::2 is within the specified namespace, while fd00::1 is a peer in the root namespace.

func SetupCrossNsDNATWithPorts

func SetupCrossNsDNATWithPorts(tb testing.TB, dport int, redirPort int) (ns string)

SetupCrossNsDNATWithPorts sets up a network namespace, a veth pair, and a NAT rule in the specified network namespace. Redirecting `dport` to `redirPort` within the namespace.

func SetupDNAT

func SetupDNAT(t *testing.T)

SetupDNAT sets up a NAT translation from: * 2.2.2.2 to 1.1.1.1 (OUTPUT Chain) * 3.3.3.3 to 1.1.1.1 (PREROUTING Chain)

func SetupDNAT6

func SetupDNAT6(t *testing.T)

SetupDNAT6 sets up a NAT translation from fd00::2 to fd00::1

func SetupSNAT

func SetupSNAT(t *testing.T) string

SetupSNAT sets up a NAT translation from: * 6.6.6.6 to 7.7.7.7 (POSTROUTING Chain)

func SetupVeth6Pair

func SetupVeth6Pair(t *testing.T) (ns string)

SetupVeth6Pair sets up a network namespace, along with two IPv6 addresses fd00::1 and fd00::2 to be used for namespace aware tests. fd00::2 is within the specified namespace, while fd00::1 is a peer in the root namespace.

func SetupVethPair

func SetupVethPair(tb testing.TB) (ns string)

SetupVethPair sets up a network namespace, along with two IP addresses 2.2.2.3 and 2.2.2.4 to be used for namespace aware tests. 2.2.2.4 is within the specified namespace, while 2.2.2.3 is a peer in the root namespace.
