ssh提示输入密码回显

/*1、启动外部进程*/
Process process = new ProcessBuilder("bash").redirectErrorStream(true).start();

/*2、执行ssh登录命令*/
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
bw.write("ssh -o PubkeyAuthentication=no -o StrictHostKeyChecking=no -t -t root@192.168.1.11");
bw.newLine();
bw.flush();

/*3、试图获取回显*/
//Thread.sleep(3000);

int len = 0;
while ((len = br.read(ch)) > -1) {

}

linux:/app # java -classpath . SSHClient
root@192.168.170.64's password:

ssh -o BatchMode=yes root@192.168.1.11

If set to “yes”, passphrase/password querying will be disabled. This option is useful in scripts and other batch jobs where no user is present to supply the password. The argument must be “yes” or “no”. The default is “no”.
