Call command through sshj

1. create a maven project
mvn archetype:generate

2. copy sshj's dependency to pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3. create logback.xml

<configuration>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
      <pattern>%d{HH:mm} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

  <!-- appender name="STDOUT"
			class="ch.qos.logback.core.ConsoleAppender">
		<layout class="ch.qos.logback.classic.PatternLayout">
			<pattern>%-4relative [%thread] %-5level %class - %msg%n</pattern>
		</layout>
	</appender -->

  <root level="off">
    <appender-ref ref="STDOUT" />
  </root>
</configuration>

4. coding App.java

package dh;

import java.io.IOException;
import java.util.concurrent.TimeUnit;

import net.schmizz.sshj.SSHClient;
import net.schmizz.sshj.common.IOUtils;
import net.schmizz.sshj.connection.channel.direct.Session;
import net.schmizz.sshj.connection.channel.direct.Session.Command;

public class App {
	private static final String df_command = "df -g|head -3|tail -2";
	private static final String recon_command = "/tmp/xx/pps-recon.sh";
	private static final String user = "root";
	private static final String passwd = "pass3822";
	private static final String wap01fingerprint = "5a:34:f2:12:5f:2b:6c:8a:7d:8e:f0:1b:ca:1a:cb:f7";
	private static final String wap02fingerprint = "2a:97:e4:7b:50:e2:8a:5c:38:ae:d4:bf:fa:8c:ee:01";

	public void diskCheck() throws IOException {
		run("10.13.135.71", wap01fingerprint, df_command);
		run("10.13.135.72", wap02fingerprint, df_command);
	}

	private void restartRecon() throws IOException {
		run("10.13.135.71", wap01fingerprint, recon_command);
		run("10.13.135.72", wap02fingerprint, recon_command);
	}

	private void run(String host, String fingerprint, String command)
			throws IOException {
		final SSHClient ssh = new SSHClient();
		//ssh.loadKnownHosts();

		try {
			ssh.addHostKeyVerifier(fingerprint);

			ssh.connect(host);
			ssh.authPassword(user, passwd);
			final Session session = ssh.startSession();
			try {
				final Command cmd = session.exec(command);
				System.out.println("<<" + host + ">> -- " + IOUtils.readFully(cmd.getInputStream())
						.toString());
				cmd.join(5, TimeUnit.SECONDS);
				//System.out.println("\n** exit status: " + cmd.getExitStatus());
			} finally {
				session.close();
			}
		} finally {
			ssh.disconnect();
		}
	}

	public static void main(String... args) throws IOException {
		App app = new App();
		app.diskCheck();
		app.restartRecon();
	}
}

5. run: mvn compile package

6. file structure as below:

src

├─main

│  ├─java

│  │  └─dh

│  │          App.java

│  │

│  └─resources

│          logback.xml

│

└─test

    └─java

        └─dh

                AppTest.java

 7. run program in command line
run.bat
