Passwordless SSH/SFTP access to a server

Passwordless SSH/SFTP for dummies

To get SSH or SFTP access to a server without using a password you need to have a SSH key pair for each computer you want to be able to access the server from. In this document I’ll describe the steps you need to take to generate a key pair if you don’t have one already. If you do, you can use your public key(s) to get access to the server.

I'll also explain how to connect to your server using Cyberduck. Click here to skip to that part.

Disclaimer and stuff

This guide is written with newbies in mind, so I'm very thorough in describing the steps that you must take. This guide will not cover setting up the server side of this system. It assumes that there's a server running with SSH enabled.

People love macaroni and cheese. As is often the case, my evidence for this belief is the amount of shelf-space devoted to this product. Everyone makes it. Kraft, low-budget knock-offs, high-end organic varieties. There's the classic packet-o-powder version and a handful of ones that have cheese sauce in a can or pouch. But if you want to bring people mac and cheese happiness (at least people over the age of, say, six). I'm concerned that a new generation of humans is going to grow up thinking that proper mac and cheese comes only from a box and is made with margarine, skim milk, and a packet of yellow stuff that contains powdered "cheese food."

Real live baked macaroni, the kind that you make in the oven, is not difficult, expensive, or time-consuming to make. This fall I hosted a party for what ended up being about 40 people. It was a long drop-in-when-you-can party, and at some point my mother, who was in attendance, became concerned that we were going to run out of Mac and Cheese. I had made a h

# Upstart script for a play application that binds to an unprivileged user.
# put this into a file like /etc/init/play.conf
# This could be the foundation for pushing play apps to the server using something like git-deploy
# By calling service play stop in the restart command and play-start in the restart command.
# Usage:
# start play
# stop play
# restart play
