I would like to try running an Apache Web server with WebDav so I can offer 'Web Folders' to a Windows XP user. How do I tell if I have Apache? How can I get it if I don't? If I am already running another HTTP server how can I tell and turn it off? Thanks.

Look it up in your package manager, and install it if you don't have it.

What distro are you running? Most of the ones I can think of do not include apache running as default, so I'm pretty sure you don't have it. To check type:
ps -A | grep apache

This will list all the processes running and then give you the results which have that process name. If nothing shows up, then you aren't running apache. Depending on your distro, you may be able to use its package management (like apt-get, emerge, rpm) to install apache for you. Otherwise you can go to the apache site and get the files you need.

FYI, apache only make source available, I've been ubale to find binary tarballs yet.

You could try a few things from the command line:

1. go to /etc/ and look for an apache.conf file or httpd.conf file. If you see either of these you have apache installed.

2. type ps -aux | less and look for something that says apache or httpd. If you see either of those then apache is running.

3. type apachectl stop and then apachectl start. If you get corresponding messages that don't look like errors then you've stopped and started apache.

4. YMMV - depending on the distro it could be installed different places. Mine, or instance are in /usr/local/apache2 so I need to type /usr/local/apache2/apache2ctl stop, etc.

Hope this helps.

Well I have Apache running and get the test page to appear. I want to let someone remotely use Web Folders from an XP machine. How can I make Apache use SSL and know that my password security is in place.
Thanks - Scott
