@microsoft/dev-tunnels-ssh-tcp
Advanced tools
Includes SshClient
and SshServer
convenience classes for establishing SSH
sessions over TCP, and the PortForwardingService
class that enables forwarding
TCP ports between client and server.
// Port-forwarding is not enabled by default. It must be added to the session configuration
// on both client and server sides.
const config = new SshSessionConfiguration();
config.addService(PortForwardingService);
const client = new SshClient(config);
const session: SshClientSession = await client.openSession(host, port);
// Handle server and client authentication.
session.onAuthenticating((e) => { ... });
if (!(await session.authenticate(credentials))) {
throw new Error('Authentication failed.');
}
// Start port-forwarding.
const pfs = session.activateService(PortForwardingService);
const forwarder: RemotePortForwarder = await pfs.forwardFromRemotePort('::', remotePort);
// Connections to the port on the server will now be forwarded to
// the same port on the client.
forwarder.dispose();
// New connections to the server port are no longer forwarded.
// (Existing forwarded connections may remain alive until the session is closed.)
const session: SshClientSession = ...
const pfs = session.activateService(PortForwardingService);
const stream: SshStream = await pfs.streamToRemotePort('localhost', remotePort);
// The stream data is forwarded to/from the port on the server.
This package has limited capabilities when running in a browser. Obviously a browser
cannot access local TCP ports. However, it is possible to stream to/from
server ports. The streamFromRemotePort()
and streamToRemotePort()
methods are
validated working in a browser environment.
