Ganymed SSH2 analog putty Remote Interactive Execution Command tool

Then the introduction of the previous article http://blog.csdn.net/doctor_who2004/article/details/47322105:

We simulate interactive execution of remote commands such as the following putty:

Import Java.io.bufferedreader;import Java.io.ioexception;import Java.io.inputstreamreader;import Java.io.printwriter;import Java.nio.charset.standardcharsets;import Java.util.scanner;import Java.util.concurrent.executorservice;import Java.util.concurrent.executors;import Java.util.concurrent.TimeUnit; Import Org.apache.commons.io.ioutils;import Org.slf4j.logger;import Org.slf4j.loggerfactory;import Ch.ethz.ssh2.connection;import Ch.ethz.ssh2.session;import ch.ethz.ssh2.streamgobbler;/** * Analog Interactive terminal * * @author doctor * * @time August 6, 2015 * * @see Http://www.programcreek.com/java-api-examples/index.php?api=ch.ethz.ssh2.SCPClient * */pub LIC final class SSHAgent2 {private Logger log = Loggerfactory.getlogger (GetClass ());p rivate Connection Connection; Private Session session;private bufferedreader stdout;private printwriter printwriter;private bufferedreader stderr; Private Executorservice service = Executors.newfixedthreadpool (3);p rivate Scanner Scanner = new Scanner (system.in); public void INitsession (String hostName, String userName, String passwd) throws IOException {connection = new connection (hostName); con Nection.connect (); Boolean authenticatewithpassword = Connection.authenticatewithpassword (UserName, passwd); Authenticatewithpassword) {throw new RuntimeException ("Authentication failed. Please check hostName, userName and passwd ");} Session = Connection.opensession (); Session.requestdumbpty (); Session.startshell (); stdout = new BufferedReader (new InputStreamReader (New Streamgobbler (Session.getstdout ()), standardcharsets.utf_8)); stderr = new BufferedReader (new InputStreamReader (New Streamgobbler (Session.getstderr ()), standardcharsets.utf_8));p rintwriter = new PrintWriter ( Session.getstdin ());} public void ExecCommand () throws IOException {Service.submit (new Runnable () {@Overridepublic void run () {String Line;try { while (line = Stdout.readline ())! = null) {System.out.println (line);}} catch (IOException e) {e.printstacktrace ();}}}); Service.submit (New Runnable () {@Overridepublic void Run () {while (true) {try {TimeUnit.SECONDS.sleep (1)} catch (Interruptedexception e) {e.printstacktrace ();} System.out.print ("Input:"); String nextline = Scanner.nextline ();p rintwriter.write (nextline + "\ r \ n");p Rintwriter.flush ();}});} public void Close () {ioutils.closequietly (stdout); ioutils.closequietly (stderr); ioutils.closequietly (PrintWriter) ; ioutils.closequietly (scanner); Session.close (); Connection.close ();} /** * @param args * @throws ioexception */public static void Main (string[] args) throws IOException {SSHAgent2 sshagent = New SSHAgent2 (); Sshagent.initsession ("127.0.0.1", "Doctor", "xxxx"); Sshagent.execcommand ();//Sshagent.close ();}}

Here read and write stream I separately in different threads, to prevent the blocking between read and write streams, simple simulation of the interactive environment. Of course, the login is the local system, no virtual machine installed, and so on.
