Functions

func RunShim

func RunShim(fd int, tunif string, mtu uint16, addr string, domain string, dnsServer string) error

func WithMTU

func WithMTU(mtu uint16) func(*newParams)

WithMTU sets the MTU for the tunnel interface in the namespace.

func WithShimBin

func WithShimBin(shimBin string) func(*newParams)

WithShimBin sets the path to the netns_shim binary. Used for testing - normal users do not need this.
