Python: How do I set the password on an ubuntu user account using Fabric

I'm trying to create a user account on a remote Ubuntu system using Fabric. I want the account to have a strong password. I can use the following to create the account:

 sudo('useradd -m test -s /bin/bash')

The problem is I'm not sure how to set the password. The useradd -p options requires an encrypted password. How do I set the password? How does the salt get passed to the remote system?

Example code would be appreciated.

Thanks

I do it like this:

sudo('useradd %s' % username)
sudo('echo %s | passwd %s --stdin' % (username, username))
sudo('chage -d 0 %s' % username)

The password will match the username and the user will be prompted to change their password at first login.

Try chpasswd. Unlike passwd, you can pass the username and password in the command's standard input. So you can for example upload a file containing the password and put this line in your fabfile: 

sudo('chpasswd < my_password_file')

From man chpasswd:

The chpasswd command reads a list of user name and password pairs from standard input and uses this information to update a group of existing users. Each line is of the format:

user_name:password

The supplied passwords must be in clear-text.
