Speed up access via SSH by making aliases. This means that typing something like:
ssh -i '~/.ssh/your-private-key' firstname.lastname@example.org

1. Navigate to ~/.ssh . and create a config file.
2. Open the file in nano and for each server alias required, add a block like below.
# Example Host example HostName example User user1 IdentityFile ~/.ssh/example-key
3. Then so long as the key exists and has suitable permissions, ssh to your server as simple as:
This saves a lot of time when dipping in and out of multiple machines on a daily basis. If there is a permission warning shown the keys permission can be updated:
chmod 600 ~/.ssh/example-key
