Locust slave will not start when attempting to start via Node.js SSH2 connection.

[vital101]

Description of issue / feature request

Whenever I attempt to start a slave via an SSH session created via the Node.js ssh2 package Locust never starts. Adding --logfile and --loglevel arguments don't yield any useful information. In fact, the logfile is never created.

I have the locust command wrapped in a simple bash file. When I log in to the slave and execute the bash script things work as expected.

Expected behavior

Locust slave starts and stays started.

Actual behavior

Locust does not start. More information at https://stackoverflow.com/questions/52745003/locust-slave-wont-star-running-when-executed-via-bash-script-when-using-node-ss

Environment settings (for bug reports)

• OS: Ubuntu 16.04
• Python version: Python 2.7
• Locust version: 0.9.0

Steps to reproduce (for bug reports)

Command being executed inside of bash script:

locust --slave --master-host=<masterIpAddress> --logfile=/root/locustlog.log --loglevel=debug &

Node.js code for executing bash script:

await ssh.connect({
    host: ipAaddress,
    username: "root",
    privateKey,
});
const command = "/bin/bash /root/start.sh";
await ssh.execCommand(command, { options: { pty: true } });

It is worth noting that the bash script has +xrw privileges.
