Getpass error(s)

Question

The following fabric script is open source which I need to use, unfortunately I'm not familiar with this stuff. The fabric file starts with:

from fabric.api import *
import time

env.user = 'aegir'
env.shell = '/bin/bash -c'

# Download and import a platform using Drush Make
def build_platform(site, profile, webserver, dbserver, makefile, build):
  print "===> Building the platform..."
  run("drush make %s /var/aegir/platforms/%s" % (makefile, build))

The fabric file is run by a Jenkins server when a new build is triggered by a Git push. When this file is executed this first remote action (last line) results in the following error.

/usr/lib/python2.6/getpass.py:83: GetPassWarning: Can not control echo on the terminal.
  passwd = fallback_getpass(prompt, stream)
Warning: Password input may be echoed.

Do I have to specify a password for the aegir user or so? I tried to include env.password = '' (I deleted the Aegir's user password with passwd --delete aegir on my remote machine) under env.user = 'aegir', but that didn't solve anything.

Answer 1

Ssh service forbid remote access for users without password. You can just set password for aegir user, on machine and in a fabfile.

Answer 2

Login required. To avoid interactivity, you can copy the public key from the FABRIC machine and paste in the TARGET machine's ~/.ssh/authorized_keys

Make sure that: Not to include or exclude anything that's not the key (like introduce linefeeds), the key must be copied exactly as is.

and do this:

chmod 600 ~/.ssh/authorized_keys
chmod 700 ~/.ssh/*
