Application Server Access

Typing out ssh -o "IdentitiesOnly yes" -i ~/.ssh/id_series admin@45.55.209.211 is annoying. Very annoying.

We'll see how to make this easier!

Add the following configuration to your local workstation user's SSH configuration file:

# Add/Edit local user's ssh config
vim ~/.ssh/config

Add the following to log into our previous created user with the SSH key we created.

Host series-admin
    HostName 45.55.209.211
    User admin
    IdentitiesOnly yes
    IdentityFile ~/.ssh/id_series

We can use many options there - just about all the ones you see if you use the man ssh command.

After that configuration is added, we can now simply log in using the following:

ssh series-admin

More Users

We can add an additional configuration to log in as our "serial" application user as well!

Make the configuration file look like this:

Host series-admin
    HostName 45.55.209.211
    User admin
    IdentitiesOnly yes
    IdentityFile ~/.ssh/id_series

Host series-app
    HostName 45.55.209.211
    User serial
    IdentitiesOnly yes
    IdentityFile ~/.ssh/id_series

Now we can quickly use SSH to log in (and copy files!) to our production server without having to re-type all the various options you might need to connect.
