Configuring SSH

To stop having to log in each time with ssh there are some things you can do.

Vi/vim ~/.ssh/config and add:

Host *
    UseKeychain yes

Or you can be more specific:

host 20.30.40.*
  user myuser
  identityfile ~/.ssh/custom_id

To add to your keychain:

ssh-add -K ~/.ssh/custom_id

The -K means when adding identities, each passphrase will also be stored in the user's keychain.
