We're going to dive out now and take a look at a
graphical build of openSUSE 15.2.
Both SUSE and openSUSE have great graphical tools for managing the
system, so let's take a look at some of the tools on offer.
Now, of course, the command line does work very well when you're used to it,
but when you're just getting started,
it is nice to know there are some great graphical tools around.
Here we've got a graphical install of openSUSE.
If I go through and look at all of my applications, we see all of the icons.
If I go onto the second page, I'll be able to access the YaST utility,
yet another setup tool.
If we fire this up,
it becomes a very good way that we can access almost a
control panel to manage our system.
Of course, I need to elevate my privileges to go in,
but as we then look at it,
we've got separate modules that we can use to manage
different parts of the system.
They're grouped together on the left.
So, for example, I can then move into Security and Users,
and I'll be able to see how we could, let's say,
create users and groups.
I can look at the sudo configuration management.
We can look at the firewall management.
We can move into network services where we can see that we can
configure many of our networking services,
which is really useful when we're getting into Linux management,
and we're not quite confident at working with the command line.
Now we used to have a certificate authority module under Security and Users,
but that's no longer included by standard.
There is, though,
a third‑party utility in the standard repositories that we can use.
If I move to Activities and I can just search for my terminal,
it's still just easier for me to install software through the command line.
If I go through and just expand the font a little bit,
we're able then to go through and use the graphical command line in
the same way as we would within our SSH connection.
So here I'm going to elevate my privileges,
and we're going to use zipper, the software installer,
to install tinyca2, that's the package that we want.
We can go ahead and search for the package,
and whilst there finding it in our standard repositories,
and we can just use y to accept, and then allow the process to run through.
Having installed it,
we're going to be able to access it through our graphical tools.
So again, Activities, and it's probably just easier to search for it, TinyCA2,
which then gives me a nice graphical interface to
managing my certificate authority.
The name for local storage is just setting up a directory to put the files in.
I can set up my common name.
I'm just going to call that myca.
Our country code, it wants a country code,
we don't normally need to put one in, but this insists on a country code.
Of course, setting our password so we can confirm our security.
And we can see we've got the same basic configuration as we saw before,
and then just go through and click OK.
So it's as easy as this creating our certificate authority,
and we don't need to worry about learning the command‑line tools.
However, of course, long term,
we're probably going to want to manage it from the command line,
but again, gives me an easy access to it when I'm just learning.
So let's now move back to our slides so we can summarize a little of what we've seen.
