Functions

func TunnelLoop

func TunnelLoop(rpc rpcpb.SliverRPCClient) error

TunnelLoop - Parses incoming tunnel messages and distributes them

to session/tunnel objects

Types

type ChannelProxy

type ChannelProxy struct {
	Rpc     rpcpb.SliverRPCClient
	Session *clientpb.Session

	BindAddr        string
	RemoteAddr      string

	DialTimeout     time.Duration
}

ChannelProxy binds the Sliver Tunnel to a net.Conn object one ChannelProxy per port bind.

Implements the Target interface from tcpproxy pkg
