Hey, hello, and welcome back.
We're ready now to summarize both this module, but also to congratulate you
on completing the module, but also completing the course.
Really well done.
That's a big, big task that you've done, and you should be very,
very proud of yourselves.
Hey, hey, that's enough.
Don't get carried away.
We've been taking a look at using systemd inside of our troubleshooting. We
saw that we could go through, and this was so powerful,
wasn't it, such a simple command, but seeing how long the boot process actually
took. But we didn't stop there, we were able to go through and add in that extra
option, blame, so we're able to see the speed at which each individual service
started, with the slowest ones being listed first, because obviously that's
where our attention needs to be.
We then went back and looked at some of our very basic tools,
so using systemctl and cat to be able to look inside of our service unit file.
Now if there's anything we didn't understand from that service unit file, we
could go through and take a look in our man page, so our man systemd.service.
But one of the things that we saw within the SSHD unit file is that it was
making reference to a variable $SSHS_OPTS.
Now that then made us start thinking that if we needed to
start up with different options, we just need to find out
where those option files are.
So we made an edit to our default file, and we could put our service very,
very easily into a debug mode to understand more about
what's going on with our SSHD service.
And honestly, we didn't have any issues at the time,
but it gives you just the idea of how you can start troubleshooting by
reading information that we have inside of our unit files.
But as I say, that's it, and a big well done to you for getting
through this module, but most importantly,
if you are now finished with the course,
congratulations on finishing the course.
I really want to give you my heartfelt thanks for both watching this and
all of the other modules that made up this course. Thank you so much for your support now and your continued support in the future.
