Ganymed SSH-2 for Java series 3 execution remote shell command __java

Connect to the remote server using ganymed SSH-2 for Java, and then execute the shell command;

First, we add a method to execute the shell command in the previous Commandrunner class, as shown in the following example:

public static string Execshellscript (string host, string username, string password, string cmd, int port) throws IO

		Exception {if (logger.isinfoenabled ()) {Logger.info ("running SSH cmd [+ cmd +]");

		} Connection conn = null;

		Session sess = NULL;

		InputStream stdout = null;

		BufferedReader br = null;
		StringBuffer buffer = new StringBuffer ("exec result:");  Buffer.append (System.getproperty ("Line.separator"));/newline try {conn = getopenedconnection (host, username, password,

			Port);

			Sess = Conn.opensession ();

			Sess.execcommand (CMD);

			stdout = new Streamgobbler (Sess.getstdout ());

			br = new BufferedReader (new InputStreamReader (stdout)); while (true) {//Attention:do not comment this block, or you'll hit//NullPointerException/when

				are trying to read exit status String = Br.readline ();
				
				if (line = = null) break;
				Buffer.append (line); Buffer.append (System.getproperty ("Line.separator);//NewLine if (logger.isinfoenabled ()) {logger.info (line);

			}}} finally {Sess.close ();

		Conn.close ();

	return buffer.tostring ();
 }

Test code:

public static void Main (string[] args) {
		
		String cmd = "uname-a";
		
		try {
			String info = commandrunner.execshellscript ("172.16.18.141", "root",
					"123456", cmd,22);
			
			SYSTEM.OUT.PRINTLN ("info is:" +info);
		} catch (IOException e) {
			e.printstacktrace ();
		}

	}

Execution results

Log4j:warn No Appenders could is found for logger (Com.ssh2.shell.ganymed.CommandRunner).
Log4j:warn Please initialize the log4j system properly.

At this point, the simple method of connecting the remote server to execute the shell command is implemented.
