SshWrapper ssh = new SshWrapper();
try {
ssh.connect("10.206.19.80", 22);
ssh.login("*****","*****");
ssh.setPrompt("c898vqz:~");
ssh.waitfor("#");
System.out.println("PWD**********"+ssh.send("pwd"));
ssh.disconnect();
System.out.println(ssh.getClass());
} catch (java.io.IOException e) {
e.printStackTrace();
}
getting nullfrom ssh.send("pwd")

You could use SSHcomponent JCraftfor remote connection and shell commands invocations:
您可以使用SSH组件JCraft进行远程连接和 shell 命令调用：
import com.jcraft.jsch.*
Exerp from my old code:
Exerp 来自我的旧代码：
JSch jsch = new JSch();
String command = "/tmp/myscript.sh";
Session session = jsch.getSession(user, host, 22);
session.connect();
Channel channel = session.openChannel("exec");
((ChannelExec)channel).setCommand(command);
channel.setInputStream(null);
((ChannelExec)channel).setErrStream(System.err);
InputStream in = channel.getInputStream();
channel.connect();
byte[] tmp = new byte[1024];
while (true) {
while (in.available() > 0) {
int i = in.read(tmp, 0, 1024);
if (i < 0) {
break;
}
System.out.print(new String(tmp, 0, i));
}
if (channel.isClosed()) {
if (channel.getExitStatus() == 0) {
System.out.println("Command executed successully.");
}
break;
}
}
channel.disconnect();
session.disconnect();
You can also easily transfer files via session.openChannel("sftp").
您还可以通过session.openChannel("sftp").
ooph.. in javait is too wordy, than e.g. in rubyor python:)
哎呀.. injava太罗嗦了，比 inruby或python:)

JSch js = new JSch();
Session s = js.getSession("username", "ip", port);
s.setPassword("password");
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
s.setConfig(config);
s.connect();
System.out.println("connection ");
Channel c = s.openChannel("sftp");
ChannelSftp ce = (ChannelSftp) c;
ce.connect();
System.out.println("connection ");
ce.disconnect();
s.disconnect();
