Java - Jsch sudo command.
I am using Jsch and my task is to login to server and run command as following
sudo su - bumboo
Using following code i am successfully able to connect but when i try to run command it gives me error sudo: sorry, you must have a tty to run sudo
Following is my code
public static Channel sudoBamboo(Session session, String sudo_pass) throws Exception {
ChannelExec channel = (ChannelExec) session.openChannel("exec");
//SUDO to bamboo user
String command = "sudo su - bumboo";
channel.setCommand(command);
//InputStream in = channel.getInputStream();
channel.setInputStream(null, true);
OutputStream out = channel.getOutputStream();
//channel.setErrStream(System.err);
channel.setOutputStream(System.out, true);
channel.setExtOutputStream(System.err, true);
//Test change
//channel.setPty(false);
channel.connect();
out.write((sudo_pass + "\n").getBytes());
out.flush();
return channel;
}
jsch in sudo.java available example they advised to use
// man sudo
// -S The -S (stdin) option causes sudo to read the password from the
// standard input instead of the terminal device.
// -p The -p (prompt) option allows you to override the default
// password prompt and use a custom one.
((ChannelExec)channel).setCommand("sudo -S -p '' "+command);
but when i run command like "sudo -S -p - su bamboo" still gives me the same error
any help appreciated.
