If you're accessing Linux servers or automating tasks between servers, rather than having to enter your user password every time, you can also use SSH public key authentication. This is a simple process that involves creating a local key and storing it within the *authorized_keys* file on the remote server.
|
|
|
|
1. Check if you already have a SSH key.
|
|
`$ ssh-add -L`
|
|
2. If you don't have one, create one.
|
|
`$ ssh-keygen`
|
|
2. Upload the key onto the server. Replace *myserver* with the hostname or IP address of your remote server.
|
|
`$ ssh-copy-id myserver`
|
|
|
|
If you're using Mac OS X and you don't have ssh-copy-id installed, download and install [Homebrew](http://mxcl.github.com/homebrew "Homebrew") and run the `brew install ssh-copy-id` command.
|
|
|
|
If successful, you should now see a message like:
|
|
|
|
> Now try logging into the machine, with "ssh 'myserver'", and check in:
|
|
>
|
|
> ~/.ssh/authorized_keys
|
|
>
|
|
> to make sure we haven't added extra keys that you weren't expecting.
|
|
|
|
Now the next time that you SSH onto the server, it should log you in without prompting you for your password.
