Summary

We just scratched the surface of what we can actually do with SSH. There are so many things such as ssh-agent, ssh-add, and ssh-keyring, and so many complex and tricky things to do that a chapter cannot hold everything. Anyway, this is a starting point; and once we get familiar on the usage of both the server and the client, we can start a journey in the esoteric world of encrypted connections, jumphosts, proxies, and whatever we need or we want to know. As of now, we need to step further to another topic that will show us how to set up scheduled jobs to execute our script in a timely manner and how to properly log their execution so that we will be always able to understand what is going on with our creations. It's time for timed jobs, time to explore the at, cron and logging facilities.
