执行带有“sudo”命令的linux shell命令。使用java，无需输入所需的密码 [英] Execute a linux shell command with "sudo" using java, without entering the required password

问题描述

您好我使用ganymed-ssh2 java库在linux工作站执行远程命令成功。

但是现在有一种情况，我需要执行命令，但这需要我给一些密码...像：

  sudo / usr / bin / some_process 
输入您的密码：
  

我用这种方式实现远程cmd执行：

 会话sess = conn.openSession（）; 
 
 sess.execCommand（uname -a&&&&&&&&&& who）; 
 
 System.out.println（这是有关远程主机的一些信息：）; 
 
 InputStream stdout = new StreamGobbler（sess.getStdout（））; 
 
 BufferedReader br = new BufferedReader（new InputStreamReader（stdout））; 
 
 while（true）
 {
 String line = br.readLine（）; 
 if（line == null）
 break; 
 System.out.println（line）; 
} 
 
 
 System.out.println（ExitCode：+ sess.getExitStatus（））; 
 
 sess.close（）; 
 
 conn.close（）; 
  

恐怕不可能执行需要此库的密码的命令。 p>

有人可以给我一个解决方案或替代方案来允许这个

Thx！

解决方案

假设有一个 sess.getStdin（），你应该能够管道sudo命令的密码。

Hi I'm using ganymed-ssh2 java library to execute remote commands in linux workstation with success.

But now there is a situation where I need to execute a command but this require that i put some password...like:

sudo /usr/bin/some_process
please enter your password:  

I used to implement remote cmd execution in this way:

Session sess = conn.openSession();

sess.execCommand("uname -a && date && uptime && who");

System.out.println("Here is some information about the remote host:");

InputStream stdout = new StreamGobbler(sess.getStdout());

BufferedReader br = new BufferedReader(new InputStreamReader(stdout));

while (true)
{
  String line = br.readLine();
  if (line == null)
  break;
  System.out.println(line);
}


System.out.println("ExitCode: " + sess.getExitStatus());

sess.close();

conn.close();

I'm afraid that it's not possible to execute commands that require a password with this library.

Someone could give me a solution or alternative to allow this ???

Thx!

解决方案

assuming there is a sess.getStdin(), you should be able to pipe in a password to the sudo command.
