sudo access with no password

If you need to enable sudo access on a remote server (or any machine for that matter) but really don’t want to have to enter your password everytime, you can disable the password prompting. I combine this with adding my public ssh key so I can just get on with things, and not have to remember a million and one passwords.

rob@mail:~$ sudo cat /etc/sudoers 
# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#

# User privilege specification
root   ALL=(ALL) ALL
rails  ALL=(ALL) ALL
rob    ALL=(ALL) NOPASSWD: ALL

You can also fine grain this to disable the password prompt only for particular scripts if your user only really performs a few actions.
