Which httpd are you using? This may help?

i am following this tutorial, and am on the last 3 steps. I went to the apache2.conf file, but could not find what they had listed there. any ideas on any alternatives of doing this?

If you're using Ubuntu then, perhaps you ought to look for an Ubuntu tutorial?
Arch Linux may be different to Ubuntu so following an Ubuntu tutorial ought to be more efficient.

Try this command:

Can't you simply try find, as:

It didn't find it. Maybe it was not included in this distro.

As I said Ubuntu is not Arch and following a tutorial for the wrong distro can be very inefficient.
Edit: I think this is the correct tutorial for Ubuntu:

how do I know if ssl is now being used with my connections? is there a way to test it?

In Debian-based systems the configuration file for apache is called apache2.conf and is located in /etc/apache2/

Easy, just go to https://<yourdomain> (where <yourdomain> is the IP address or name of your machine) and your browser will tell you. You'll probably get a warning about an unrecognised certificate since it's self generated.

. . . Or look in the Software Center and see whether Apache shows as installed.

Or check to see if its set to listen on port 443 in the conf file.

To make sure Apache is listening on port 443, open the /etc/apache2/ports.conf file and verify the following exist:

Listen 443

If your Apache service is not configured to run SSL, this guide should help you setup SSL with apache2.

Or try this:
