我想用

java代码连接我的unix服务器.首先它将连接到我的服务器位置.在里面,它将连接到我的服务器名称.但那时它会要求确认(是/否)和密码我不知道该怎么做？

这是我所做的代码.请帮我解决这个问题

public static void main (String args[]) {

String user = "user";

String password = "password";

String host = "hostName";

int port=22;

//String remoteFile="/home/john/test.txt";

//String yes="yes";

try {

JSch jsch = new JSch();

Session session = jsch.getSession(user, host, port);

session.setPassword(password);

session.setConfig("StrictHostKeyChecking", "no");

System.out.println("Establishing Connection...");

session.connect();

Channel channel = session.openChannel("exec");

// After this it'll ask for confirmation and password

((ChannelExec)channel).setCommand("ssh myServerName");

channel.connect();

InputStream output = channel.getInputStream();

System.out.println("aafter stream");

int readByte = output.read();

StringBuilder outputBuffer = new StringBuilder();

while (readByte != 0xffffffff) {

//System.out.println("read byte" + readByte);

outputBuffer.append((char)readByte);

readByte = output.read();

}

System.out.println(outputBuffer.toString());

channel.disconnect();

} catch (Exception e){

System.err.print("error message" + e);

}

}

最佳答案 您需要获取JSch安全通道的OutputStream并在其中插入密码.

Channel channel = session.openChannel("exec");

((ChannelExec) channel).setCommand("sudo -S -p '' " + command);

channel.setInputStream(null);

OutputStream out = channel.getOutputStream();

((ChannelExec) channel).setErrStream(System.err);

InputStream in = channel.getInputStream();

((ChannelExec) channel).setPty(true);

channel.connect();

out.write((password + "\n").getBytes());

out.flush();
