Executing a script

A TelnetScript will begin execution as soon as a connection is established with the telnet server. Therefore it is recommended that your TelnetScript be created and all tasks added before the Telnet#connect method is invoked.

The code example below will demonstrate how to automatically login to a telnet server, execute a command and logout. Some assumptions have been made about the start and end prompts. Your system prompts will likely differ although the process would be the same.

Example

String loginPrompt = "login:";

String passwordPrompt = "Password:";

String shellPrompt = "#";

String username = "jsmith";

String password = "secret";

String command = "ls –al";

// build task to submit username

TelnetTask loginTask = new TelnetTask(loginPrompt,login,passwordPrompt);

// build task to submit password

TelnetTask passwordTask = new TelnetTask(passwordPrompt,password,shellPrompt);

// build task to execute command

TelnetTask commandTask = new TelnetTask(shellPrompt,command,shellPrompt);

// add all tasks to script

script.addTask(loginTask);

script.addTask(passwordTask);

script.addTask(commandTask);

// connect to telnet server … script is executed automatically

telnet.connect();

// wait until last task is complete

while(!commandTask.isComplete()) {

try {          

 Thread.sleep(1000);

 } catch(Exception e) {}

}

// last task completed … disconnect from server

telnet.disconnect();
