possibility to run sudo commands

[solancer]

Is it possible to run sudo commands? sending in password to the pty?

[steelbrain]

Hi @solancer

You can either use a pty to send the password or you can provide the password in stdin to exec/execCommand for example

ssh.exec('sudo', ['ls /'], { stdin: 'mypassword\n' })

\n is important after the password

That worked like a charm, thanks for taking time to develop such an awesome lib. If you ever come down to Bangalore beer's on me mate ;)

Thanks for the offer, glad you like it :)

Hi @steelbrain
I've tried your suggestion, however, I got "sudo: no tty present and no askpass program specified" error
What have I done wrong?

[steelbrain]

@SlavikVostretsov You have to pass pty: true in ExecOptions.options so it looks something like

ssh.exec('sudo', ['ls /'], { stdin: 'mypassword\n', pty: true })

[v-vostretsov]

@steelbrain Still got the same error :(
Here is my code
ssh.exec("sudo", ["mv file /home/path/"], { pty: true, stdin: "mypass\n" } )

@SlavikVostretsov In that case, it's an ssh server config issue.

Try googling with that error message to see if that helps

There's a typo, pty should in the options property

ssh.exec("sudo", ["mv file /home/path/"], { options: { pty: true }, stdin: "mypass\n" } )

As of now for version 10.0.2, the above solution is not working. Since changes in options keyword as execOptions. Below is working for me.

ssh.exec("sudo", ["mv file /home/path/"], { execOptions: { pty: true }, stdin: "mypass\n" } )

I have tried this with execOptions and stdin as the password and still getting back the prompt to enter admin's password.

    ssh.exec("sudo", ["useradd -m -s /bin/rbash userID"],
        {
            execOptions: { pty: true }, stdin: "useradmin_password\n",
            onStdout(chunk) {
                console.log(`STDOUT: ${chunk.toString('utf8')}`);
            },
            onStderr(chunk) {
                console.log(`STDERR: ${chunk.toString('utf8')}`);
                ssh.getConnection().end();
            }
        });

The response is:
STDOUT: [sudo] password for useradmin:
