]]> A while ago I wrote a tip that showed you how to copy your public SSH key to a remote server to allow you to login without entering a password every time. I’ve since put this into a script that I use, and today I got sick enough of copying that script onto yet another machine that I packaged it up as a gem, so now we can all use it.

It works just like the plain old ‘ssh’ command, but this time you’ll never have to enter your password again:

ssh-forever username@yourserver.com

Your key will be generated (if necessary), copied to your server, and you’ll be logged in as normal.

Installation

gem sources --add http://gemcutter.org
gem install ssh-forever

Example:

[matt@bowie ssh-forever (master)]$ ssh-forever mattwynne@mattwynne.net
You do not appear to have a public key. I expected to find one at /Users/matt/.ssh/id_rsa.pub
Would you like me to generate one? [Y/n]y
Copying your public key to the remote server. Prepare to enter your password for the last time.
mattwynne@mattwynne.net's password:
Success. From now on you can just use plain old 'ssh'. Logging you in...

Why?

Because I can never remember how to do it by hand. Now I don’t have to, and nor do you.
