It’s annoying having to copy & paste a password every time you want to log into your favourite Linux machine. Thankfully, it’s quite easy to set up SSH keys between two Linux machines.
Here’s a quick little process that I do when I know I’ll be either using a certain machine a lot, or when I need to rsync between two machines in an automatic fashion.
Please note: it is not the most secure of methods, and anyone that gains access to your machine will be able to access those machines you have authenticated with. I can’t take any responsibility for anything untoward that comes as a result of this.
$ ssh-keygen -t dsa -f /tmp/key # (Leave a blank passphrase) $ ssh-copy-id -i /tmp/key.pub firstname.lastname@example.org $ rm /tmp/key /tmp/key.pub
And that should be it. Next time you attempt to log into
email@example.com, you’ll be logged in straight away, without any prompt for a password. This works on Ubuntu and its derivatives (as far as I’m aware).
Hope this helps :)
