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

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