}

Config a Tunnel

type Proxy

type Proxy struct {
	*cio.Logger
	// contains filtered or unexported fields
}

Proxy is the inbound portion of a Tunnel

func NewProxy

func NewProxy(logger *cio.Logger, sshTun sshTunnel, index int, remote *settings.Remote, tlsConf *tls.Config, isClient bool) (*Proxy, error)

NewProxy creates a Proxy

func (*Proxy) Run

func (p *Proxy) Run(ctx context.Context) error

Run enables the proxy and blocks while its active, close the proxy by cancelling the context.

Tunnel represents an SSH tunnel with proxy capabilities. Both chisel client and server are Tunnels. chisel client has a single set of remotes, whereas chisel server has multiple sets of remotes (one set per client). Each remote has a 1:1 mapping to a proxy. Proxies listen, send data over ssh, and the other end of the ssh connection communicates with the endpoint and returns the response.

func New

func New(c Config) *Tunnel

New Tunnel from the given Config

func (*Tunnel) BindRemotes

func (t *Tunnel) BindRemotes(ctx context.Context, remotes []*settings.Remote) error

BindRemotes converts the given remotes into proxies, and blocks until the caller cancels the context or there is a proxy error.

func (*Tunnel) BindSSH

func (t *Tunnel) BindSSH(ctx context.Context, c ssh.Conn, reqs <-chan *ssh.Request, chans <-chan ssh.NewChannel) error

BindSSH provides an active SSH for use for tunnelling
