Types ¶
type DropCommand ¶
type DropCommand struct {
// contains filtered or unexported fields
}
DropCommand is a subcommand for dropping packets.
func (*DropCommand) Execute ¶
func (pc *DropCommand) Execute(context.Context, *flag.FlagSet, ...any) subcommands.ExitStatus
Execute implements subcommands.Command.Execute.
func (*DropCommand) Name ¶

func (*DropCommand) Usage ¶
func (*DropCommand) Usage() string
Usage implements subcommands.Command.Usage.
type PassCommand ¶
type PassCommand struct {
// contains filtered or unexported fields
}
PassCommand is a subcommand for passing packets to the kernel network stack.
func (*PassCommand) Execute ¶
func (pc *PassCommand) Execute(context.Context, *flag.FlagSet, ...any) subcommands.ExitStatus
Execute implements subcommands.Command.Execute.
func (*PassCommand) Name ¶
func (*PassCommand) Name() string

Usage implements subcommands.Command.Usage.
type RedirectHostCommand ¶
type RedirectHostCommand struct {
// contains filtered or unexported fields
}
RedirectHostCommand is a subcommand for redirecting incoming packets based on a pinned eBPF map. It redirects all non-SSH traffic to a single AF_XDP socket.
func (*RedirectHostCommand) Execute ¶
func (rc *RedirectHostCommand) Execute(context.Context, *flag.FlagSet, ...any) subcommands.ExitStatus
Execute implements subcommands.Command.Execute.
func (*RedirectHostCommand) Name ¶
func (*RedirectHostCommand) Name() string
Name implements subcommands.Command.Name.
func (*RedirectHostCommand) SetFlags ¶
func (rc *RedirectHostCommand) SetFlags(fs *flag.FlagSet)
SetFlags implements subcommands.Command.SetFlags.
func (*RedirectHostCommand) Synopsis ¶
func (*RedirectHostCommand) Synopsis() string
Synopsis implements subcommands.Command.Synopsis.
func (*RedirectHostCommand) Usage ¶
func (*RedirectHostCommand) Usage() string
Usage implements subcommands.Command.Usage.
type TcpdumpCommand ¶
type TcpdumpCommand struct {
// contains filtered or unexported fields
}
TcpdumpCommand is a subcommand for capturing incoming packets.
func (*TcpdumpCommand) Execute ¶
func (pc *TcpdumpCommand) Execute(context.Context, *flag.FlagSet, ...any) subcommands.ExitStatus

SetFlags implements subcommands.Command.SetFlags.
func (*TcpdumpCommand) Synopsis ¶
func (*TcpdumpCommand) Synopsis() string
Synopsis implements subcommands.Command.Synopsis.
func (*TcpdumpCommand) Usage ¶
func (*TcpdumpCommand) Usage() string
Usage implements subcommands.Command.Usage.
type TunnelCommand ¶
type TunnelCommand struct {
// contains filtered or unexported fields
}
TunnelCommand is a subcommand for tunneling traffic between two NICs. It is intended as a fast path between the host NIC and the veth of a container.
SSH traffic is not tunneled. It is passed through to the Linux network stack.
func (*TunnelCommand) Execute ¶
func (tn *TunnelCommand) Execute(context.Context, *flag.FlagSet, ...any) subcommands.ExitStatus
Execute implements subcommands.Command.Execute.
func (*TunnelCommand) Name ¶
