Package Exports

expect-telnet

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (expect-telnet) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

  {expect: "Password", send: "password\r"},
  {expect: "#"       , send: "command\r" },
  {expect: "#"       , out: console.log, send: "exit\r"}
], function (err) {
  if (err) console.log(err);
  // sequence done
});

// connect, log in and start an interactive session.
et("1.2.3.4", 23, [
  {expect: "Username", send: "username\r"},
  {expect: "Password", send: "password\r"},

  if (err) console.log(err);
  // sequence done
});

API

expect-telnet(host, port, seq, cb)

host string: Target host.
port number: Target port.
seq array : Array of expect steps (objects).

Expect step object

expect string : String to expect.
send string : String to send when expect is found.
out function : Output function, receives the output since the previous step.
interact boolean: Enter interacive mode with stdin/stdout. There's currently no way out of this mode, so this should be last.
